1. Field of the Invention
This invention relates to a treatment support system for emergency patients in a hospital.
2. Description of the Related Art
Eye-opening innovations have been appearing in medical scenes. Many high-tech medical instruments such as MRI and CT equipment are used for diagnosis of broad range of diseases. Application of IT (information technology) has been also rapidly advancing. For example, medical information transfer via a network to remote medical service providers has been proposed, as well as computerized diagnosis where a disease name is presumed by a computer to which information about a patient's condition is input. One of those techniques is disclosed in Japanese Publication No. 2004-280807.
However, utilization of IT in medical scenes has been insufficient for treatments of diseases, particularly for treatments of emergency patients in serious condition. In treating an emergency patient, a diagnosis and decision of a treatment plan must be done shortly after the patient has arrived to the hospital by an ambulance. An investigation and test are often required for the diagnosis. Depending on the result thereof, additional ones are sometimes required.
One particular problem in treating an emergency patient is that diagnosis cannot be established immediately. For example, a head X-ray, CT and MRI scans are carried out initially for an emergency patient complaining of headache. However, it is often impossible to establish the diagnosis from those diagnostic images. In cerebrovascular diseases particularly, sometimes it cannot be judged whether it is a cerebral infarction or hemorrhage. Even if the disease is identified, it is often difficult to decide immediately what is the best treatment option for it. For a cerebral aneurysm such as subarachnoid hemorrhage, for example, there are two treatment options: clipping and coiling. In clipping, the neck of the aneurysm is obliterated by a clip, while in coiling, a catheter is inserted into the artery carrying the lesion and the aneurysm is filled inside with specially designed coils. From a diagnostic image, it is sometimes impossible to judge which option is better.
As known, on the other hand, the survival rate of cerebrovascular disease patients would decrease more and more, when it takes a longer time from onset of disease to initiation of treatment and surgery. It is necessary that diagnosis and treatment are done in a quite short period. In ischemic stroke, for example, it was reported that the rehabilitation rate was 30 to 40% if tPA (tissue Plasminogen Activator) was administered within three hours from the occurrence, although the rate dropped off sharply if it was over three hours (Moira K. Kapral et al., Registry of the Canadian Stroke Network Progress Report 2001-2005). In such emergency medical situations as described, physicians are making decisions and performing treatments, considering them the best, relying only on their own knowledge and experience, in the battles against time.
In treating an emergency disease, however, sometimes it would be better to request an opinion of another physician specialized in the field of the disease in consideration to obtain an optimal treatment result, not relying only on decision made by the emergency physician in charge. In this case, if the other physician is on duty in the hospital, it is possible to ask him/her directly for an opinion, showing the diagnostic images. However, that is impossible if no other specialist physician is on duty in the hospital. Even there may be the case that no specialist physician in the field of the presumed disease belongs to the hospital. In such cases, there is no other way but relying solely on the knowledge of the physician in charge.
The above description is upon the premise that the physician in charge is specialized in the field of the disease. In emergency medical scenes, however, a not specialized physician often has to attend an emergency patient. For example, when a patient having a cardiovascular disease is brought to a hospital by an ambulance, it could happen that only a physician specialized in gastroenterology is on duty. In hospitals and clinics in depopulated or remote rural areas, moreover, only a physician without specialization in any medical field, the so-called “general physicians”, might be on duty. In this case, it is impossible to carry out diagnosis and treatment requiring a highly specialized judgment. In this case, because the patient cannot be treated in the medical facility, the ambulance must transfer the patient to another medical facility. In such a case, the problem of so-called “tarai-mawashi”, meaning that an emergency patient in an ambulance is rejected admission by one hospital after another, could happen.
Furthermore, even in a hospital with higher level of specialization, in which a specialist physician is always on duty, it is sometimes difficult for him/her to establish the diagnosis alone for a rare condition. Even if the diagnosis is established by his/her own knowledge and experience, sometimes it would be better to have another specialist physician's opinion. Actually, physicians manage emergences only on their own because of time constraint.
To have another physician's opinion about a disease has been done so far. A physician often tells a patient to see another physician, writing a referral letter. A patient him/herself often asks another physician for an opinion, i.e., second opinion. However, those are other-opinion requests via patients, not being that a primary physician in charge asks directly another physician for an opinion. In emergency medical situations as described, on the other hand, it is frequently desired by a physician in charge to ask another specialist physician for an opinion directly.
This invention was made considering the above problems in emergency medical services, and presents a treatment support system making it easy for a physician in charge to ask another specialist physician, especially another expert physician, for an opinion. The support system by this invention is much useful in providing an optimal treatment for an emergency disease, reviewing an expert-physician's opinion.
To accomplish the object, the invention presents a support system for a treatment of an emergency patient in a hospital, comprising
a database server including an expert-physician database file in which information of expert-physicians belonging to institutions other than the hospital is recorded, the expert-physicians being recognized as those having special knowledge and experience in specific clinical fields of diseases;
a recorder to record the information of the expert-physicians in the expert-physician database file;
a primary terminal handled by a physician in charge of treating the emergency patient in the hospital;
each secondary terminal handled by each expert-physician, the information recorded in the expert-physician database file including addresses of the secondary terminals;
a primary transmitter for transmitting an initial disease data to each secondary terminal, the initial disease data including a disease image of the emergency patient and time when the image was taken;
a received information displayer to display the initial disease data on each secondary terminal after the initial disease data is received thereon;
a secondary transmitter to transmit an opinion to the primary terminal, the opinion being input by one of the expert-physicians on one of the primary terminals;
an opinion displayer to display the opinion on the primary terminal after the opinion is received thereon, and
an alarmer to generate an alarm by sound, light, vibration or any combination thereof to each expert-physician when the initial disease data is transmitted to each secondary terminal.
In the invention, the opinion is concerning to necessity of an additional test and investigation for the emergency patient, a diagnosis for the emergency patient, or a treatment plan for the emergency patient, and the primary transmitter transmits the initial disease data with a time period for transmitting the opinion.
A preferred embodiment of the invention will be described as follows.
Although the hospital is usually designated as emergency medical facility, application of the invention is not limited only to such facilities, because an emergency patient could be occasionally admitted to a hospital not designated as emergency medical facility. The support system described below is suitable especially for treating a serious disease such as cerebrovascular diseases. The hospital is supposed to be able to admit such a serious emergency patient. Nevertheless, its use is not limited only to such hospitals.
In the following description, “terminal” means a computer capable of inputting, outputting, transmitting and receiving information via the network, and displaying the received information, and is typically a personal computer, cell phone, PDA (personal data assistant) or the like. A cell phone can be so called smart phone. “Person in charge” handling the primary terminal 1 is typically a physician in charge of treating an emergency patient. Nevertheless, “person in charge” could be another person than the physician in charge, e.g., a nurse, assistant, secretary, clerk or the like, because these persons could handle the primary terminal 1 according to the instruction by the physician in charge.
“Expert-physicians” means physicians recognized as having high-level special knowledge and experience in a specific medical field. “Experience” in this could be experience of diagnosis, experience of treatment, or the both.
Currently each academic society in each medical field qualifies a physician having special knowledge, skill and experience as “specialist physician”. A physician can initially become a “board certified specialist” after certification by an academic society or the appropriate national Board for a certain medical field. And then the physician can become a sub-specialist in a certain more narrow area of medical knowledge and practice after the required training, apprenticeships, examination and so on.
“Expert-physicians” in this embodiment are those having specialties higher than the above-described “sub-specialist”. More specifically, they are assumed to be teaching physicians or physicians on a similar level. “Teaching physicians” generally mean physicians having knowledge, skill and experience of higher levels than board certified physicians and sub-specialist physicians, and are in positions to teach even board-certified specialists. In this embodiment, physicians on the same level as the teaching physicians or on a higher level are assumed as expert-physicians. The expert-physicians in this embodiment are the partners who provide opinions as described later. What level of knowledge, skill and experience is required for the expert-physicians to participate may be decided adequately depending on situations. Therefore, even physicians at lower levels than the teaching physicians may be asked for the opinions.
The support system of this embodiment comprises a group of servers in addition to the primary terminal 1 and secondary terminals 2. The primary terminals 1 and the servers are provided on an intranet 10. The intranet 10 is connected to the Internet via a firewall (not shown) to prevent unauthorized accesses.
One of the servers is a communication server 3 acting as a communication agent between the primary terminals 1 and secondary terminals 2. Another one of the servers is a database server 4 managing database files including an expert-physicians database file (hereinafter shortly, “EP-DBF”). As other servers, a recording server 5, PACS server 6 and electronic chart server 7 are provided on the intranet 10. These servers may be provided individually. Otherwise one computer server may provide two or more server functions. In the latter case, more than one server programs are installed to one server computer in a way to play two or more different server roles.
A number of primary terminals 1 are provided for a number of hospital staff members. Each primary terminal 1 may be a desktop or notebook computer, workstation, or a mobile type such as cell phone or PDA. The computers as primary terminals 1 are connected to the intranet 10 via a wired LAN interface. Although mobile type terminals as primary terminals 1 are connected to the intranet 10 usually via a public wireless network and the Internet, those may be connected directly to the intranet 10 via a private wireless network provided in the hospital.
The hospital is equipped with a variety of equipment for tests and investigations. Some of them output images as results, such as X-ray images, CT and MR', which are hereinafter called “imaging equipment”. Although the images are often taken at diseased parts of patients, those may be at other parts related to diseases. The images are referred as “disease images” or “diagnostic images” in this specification.
A PACS (picture archiving communication system) is provided on the intranet 10, including the PACS server 6. Each primary terminal 1 can capture an image data in the PACS server 6 via the intranet 10. Moreover, an electronic chart system, which includes the electronic chart server 7, is provided on the intranet 10. Electronic chart data in the electronic chart server 7 can be acquired at each primary terminal 1 via the intranet 10 as well. Such a PACS system and electronic chart system can be available from some medical system providers. Therefore, detailed description is omitted.
Before detailed description of each part in the support system of this embodiment, a work flow of an emergency patient care utilizing the support system will be roughly described as follows.
Receiving the inquiry, the hospital decides whether the patient is admitted or not, after checking up whether any physician is able to attend, treatment equipment such as ICU is vacant, and so on. In such circumstances, when a physician specialized in the medical field of the presumable disease is off duty, a contact is made to his/her cell phone, asking whether he/she is able to get to the work with the arrival of the patient. If able, the hospital makes a reply that the patient is admissible.
When the patient arrives, condition of the patient is evaluated, and any required emergency test and investigation are carried out immediately. That may be an imaging investigation, such as X-ray, MRI or CT. The image obtained is hereinafter called “initial disease image”. Some simple evaluation and tests such as body temperature and blood pressure may be carried out in the ambulance during the delivery.
After the initial tests and investigations or in parallel with it, a new electronic chart is created for the patient. If the patient has had any medical care in the hospital so far, the chart of the patient is updated, not creating new one, with adequate timing of the progress of diagnosis and treatment.
Then it is decided whether the support system is used or not in treating the emergency patient. It means to decide whether a diagnosis or treatment is carried out asking expert-physicians belonging to other medical facilities for opinions. It is considered first if the physician in charge can make decisions on the diagnosis (diagnostic details) and treatment (treatment plan) by him/herself, whether any additional investigation and test is necessary, and so on. This support system is used, if the decisions cannot be made by the physician in charge, or if opinions of the expert-physicians should be referred to anyway.
When the support system is not used, the physician in charge by him/herself establishes diagnosis and then treats the disease as any additional investigation and test is carried out if necessary. When utilization of the support system is decided, one of the primary terminals 1 sends inquiry information to inquire in advance of each appropriate expert-physician whether he/she will be available to provide an opinion, after deciding the specialization level of the expert-physicians to inquire of.
If no expert-physicians reply “available”, it is considered to lower the specialization level of them. If not lowered, utilization of the support system is abandoned, and the diagnostic work-up and treatment are carried out only by the physician in charge. If lowered, the specialization level is set again, and then the inquiry information is sent from the primary terminal 1 again.
If at least one expert-physician replies “available”, clinical data at this moment, which include an initial disease image and is hereinafter referred as “initial disease data”, is sent to the expert-physician(s), inquiring for an opinion. The opinion is concerning the diagnosis, how it should be treated (treatment plan), or whether any additional test and investigation are necessary. The opinion could include two or more points. The opinion is the information transmitted to the support system. In the following description, the word “opinion” is used in this meaning.
The initial disease data is sent to each secondary terminal 2. Displaying the initial disease data on each secondary terminal 2, each expert-physician considers it, and then transmits the opinion from each secondary terminal 2. The opinion is received at the primary terminal 1, and confirmed by the physician in charge. Depending on the situation, a real-time communication such as chatting conference is carried out among the expert-physicians having provided the opinion and the physician in charge. Based on those steps, the physician in charge carries out a treatment after finalizing the diagnosis, an additional test (if necessary), and a treatment plan decision.
Each part of the support system of this embodiment utilized in carrying out the above work flow will be described in detail as follows. First of all, the database server 4 will be described. The database server 4, on which a database managing program is installed, has a storage, e.g., hard-disk storage. Various database files are stored in the storage. One of the database files is the EP-DBF referred before. As other files, there are an in-hospital physician database file (hereinafter, “IHP-DBF”) in which information of physicians working in the hospital is registered, a temporary case DBF in which information is registered temporarily for managing the usage of the system, and a temporary receiver DBF in which information about the secondary terminals 2 is registered temporarily on each case for managing usage of the system as well.
“Specialty Field” in the EP-DBF is the information about a clinical field in which a physician is expert. “Specialty Field Code” is the code information assigned to each specialty field for a search or other purposes. “Specialization level” is the information about how high the expertise level of the expert-physician is in the specialty field. In this embodiment, three ranks, “AA”, “A” and “B”, are given as the specialization levels. “AA” is highest, and “B” is lowest. For example, “B” may be the level of a sub-specialist physician, and “AA” may be the level of a teaching physician who is famous as authority in a clinical field, whereas “A” may be a middle level between them.
In addition, information about medical institutions to which the expert-physicians belong is registered in the EP-DBF. Although not shown, the fields “Profile” and “Number of Operated Cases” are provided in the EP-DBF as referential information to presume the specialization level, “Number of Operated Cases” is the information about how many times the expert-physician has carried out surgeries. Of course, it means how much experience the expert-physician has. Although not shown either, the field “Terminal Type” is given in the EP-DBF. This is where the kind of each secondary terminal 2 is registered, e.g., “3G cell phone”, “smart phone”, “personal computer” or the like. This information is used for selecting the compression level of an image data as described later.
The support system of this embodiment comprises a register registering the above described information about the expert-physicians. One of the primary terminals 1 is provided as an administration terminal which a secretary in the hospital handles. The above described information of the expert-physicians are input at the administration terminal and recorded in the EP-DBF for registry. Therefore, the register is composed of the administration terminal, the database server 4 and other components.
Advance agreements to record the information on the database server 4 are provided from the expert-physicians, who are receivers of the inquiry information described later. Each expert-physician sends the information via E-mail, facsimile or regular mail. The secretary handles the administration terminal to access the database server 4, inputs the information sent by each physician, and records it in the EP-DBF.
The terminal identification information or other information may be obtained by a secondary terminal 2 when it makes an access to the communication server 3 via the Internet, because of convenience. For example, an E-mail in which access information to the communication server 3 (e.g., URL) is written is sent to a secondary terminal 2, and then makes the secondary terminal 2 access to the communication server 3. The communication server 3 reads out the terminal identification information and E-mail address from the session information in the access, and sends them to the database server 4 to record thereon. Because this part of the system can be the same as in many web sites having membership registrations, detailed description is omitted.
The IHP-DBF will be described as follows. Although a figure is omitted, the IHP-DBF is the database file having the fields of “In-hospital Physician ID” given to each in-hospital physician, “In-hospital physician Name” and “Clinical Department”. A password has been issued to each in-hospital physician. Each password is also recorded in the IHP-DBF.
The temporary case DBF and temporary receiver DBF will be described in detail as follows.
The communication server 3 will be described next in detail. The communication server 3 is to implement a server-client environment in relation to the terminals 1, 2, thereby providing various services and information. One of these important services is being an agent in exchanging information among the terminals 1, 2. Because the information exchange is in many cases done by E-mail transmissions, a server-side program for E-mail transmissions (i.e., MTA) is installed on the communication server 3, for example, sendmail, qmail or the like. In addition, the communication server 3 is capable of providing web pages via HTML protocol and forwarding files via FTP. Because those are the same as in usual web servers, detailed description is omitted.
The support system of this embodiment comprises an initial transmitter to transmit the initial disease data. As components of the initial transmitter, the support System comprises the communication server 3 and an initial transmission program installed on the communication server 3. In addition to the initial transmission program, some special programs for services using the support system are installed on the communication server 3. These programs are related to each other and integrated. For convenience of description, “project” is introduced as the generic word for programs. The group of the integrated programs on the communication server 3 is hereinafter referred simply as “support project”.
Each program in the support project is written in an object-oriented programming language such as Java or VB (Microsoft Visual Basic). In the storage of the communication server 3, files for displaying form windows (hereinafter simply “forms”) on the terminals 1, 2 are memorized. The files for displaying forms are hereinafter referred simply as “form files” In each form file, a button to start a program in the support project (command button) may be embedded. In the forms displayed by the form file, the inquiry information and the initial disease data are input. A form file is sent to a terminal 1, 2 from the communication server 3 when requested, and then the form is displayed on the terminal 1, 2. Each program in the support project is installed at a predetermined URL (e.g., http://www.99medical.gr.jp/project/). Information transmissions among the terminals 1, 2 are carried out via this URL. When one of the terminals 1, 2 is accessing this URL, a variety of information is stored to session variables, thereby exchanging information among the terminals 1, 2 and among forms.
Many programs in the support project are to make each primary terminal 1 in the hospital carry out treatment support works. A menu form for executing those programs is provided. A form file of the menu form, hereinafter, “menu form file”, is stored in the storage of the communication server 3.
As shown on
As shown on
The support system of this embodiment comprises an inquiry information transmitter to transmit the inquiry information from a primary terminal 1. As components of the inquiry information transmitter, the support system comprises the communication server 3 and an inquiry information transmission program. More concretely, a command button 33 with the title “Inquiry Information Transmission”, hereinafter, “inquiry transmission button”, is provided in the menu form as shown in
The patient arrival time input box is the box in which date and time when the emergency patient has arrived at the hospital are input. By clicking a command button with the title “time/calendar”, time and a calendar are shown by pulldown lists, so that the delivery time and date can be input easily by choosing items in the lists. The patient sex input box is a radio button, where either one is selected. The patient age input box comprises a pulldown list showing the numbers of age, where any number is selected.
The patient ID input box is filled in if the ID is known at this stage. If an emergency patient is brought to the hospital with his/her family or having a medical insurance card or a patient ID card issued by the hospital, the patient ID is input. If only the medical insurance card is held, the patient ID is acquired by searching the electronic chart server 7.
The initial observation input box 34 is a textbox, in which initial observation about the condition of the emergency patient is input in text. The initial observation is informed the expert-physicians in inquiring whether they can provide opinions on this case or not. For example, text information such as “he arrived complaining of a severe headache” or “xx is suspected” is entered. If the disease is neurological, some specific neurological observation and data (such as consciousness level or neurological condition of the patient) are often included.
The clinical field input box comprises a pulldown list of clinical fields. In this box, a clinical field selected from the list is input. This is the field where the expert-physicians, whom the physician in charge would like to ask to provide opinions, have specialties. The clinical field is determined or presumed from the patient's condition at the time of the initial observation.
The specialization level input box is where the expertise level of the expert-physician who is asked to provide the opinion is input. Because it is chosen from “AA”, “A” and “B” in this embodiment, the box comprises a pulldown list of those. If “AA” is chosen, it means that the physicians on the AA level are chosen. If “A” is chosen, it means that the physicians on the levels of A or higher, i.e., AA and A levels, are chosen. If “B” is chosen, it means that the physicians on the levels of B or higher, i.e., AA, A and B, are chosen.
The reply period input box is where the period to reply the opinion availability is input. For example, it is set as a time period from an inquiry information transmission, such as “within one hour”, “within three hours”, “within five hours” or “within seven hours”. Instead of this, the period may be set as the time and date as a limit, such as “by 19:00 today”, “by 21:00 today” or “by 23:00 today”.
The box with the title “Physician in Charge” is automatically filled in, according to the in-hospital physician ID input in a certification window which is displayed prior to the inquiry information input form. The in-hospital physician ID input in the certification is stored to a memory variable. In displaying the inquiry information input form, it is read out and used as a search key to search the IHP-DBF. By this, the name of the in-hospital physician is acquired and filled in the box of the form.
If any corresponding record exists, the expert-physician ID, the expert-physician name and the terminal address are read out therefrom and memorized in memory variables temporarily. After finishing the search through all the records in the file, the program creates a new case ID and adds a new record in the temporary case DBF. The new case ID, the in-hospital physician ID and the inquiry information transmission time are recorded in the added new record in the temporary case DBF. Then the program creates a new temporary receiver DBF under the filename of the case ID. The information of the expert-physician ID, the expert-physician name and the terminal address, which have been read out from each corresponding record in the EP-DBF, is recorded in each new record of the new temporary receiver DBF. Afterward, the program reads out an E-mail form stored in the storage of the communication server 3, and lays the information input in the inquiry information input form. And then the program sends the E-mail to each terminal address in order.
The support system of this embodiment comprises a means for receiving and displaying the information transmitted from the communication server 3. As components of the means, the support system comprises each secondary terminal 2 and a receiving displaying program, hereinafter, “RD program”. Because information is sent via E-mail in this embodiment, the RD program is an E-mail program, i.e., mailer, installed in each secondary terminal 2.
The E-mail in which the inquiry information is laid, hereinafter, “inquiry E-mail”, is transmitted to each secondary terminal 2 via the Internet as described. The inquiry E-mail is received and displayed at each secondary terminal 2 by the RD program.
As shown in
The support system of this embodiment comprises an availability information transmitter to transmit availability information from a secondary terminal 2 to a primary terminal 1. The availability information is regarding if an opinion can be provided or not. As components of the availability information transmitter, the support system comprises availability transmission buttons laid in the inquiry E-mail, the communication server 3, and an availability information transmission program.
As shown in
The availability information transmission program is a server-side program. That is, the program is installed in the communication server 3 and executed by the availability information transmission buttons. The created case ID and a code meaning availability are embedded in each availability information transmission button. In the available button, more concretely, there is an embedded command to execute the availability information transmission program with the case ID, a code meaning “available” and a sender address (i.e., the address of a secondary terminal 2) as arguments. In the unavailable button, more concretely, there is an embedded command to execute the availability information transmission program with the case ID, a code meaning “unavailable” and the sender address as arguments.
The availability information transmission program opens the temporary receiver DBF where the case ID is the filename, and record the availability information (i.e., available or unavailable) in the field “Availability” of the corresponding record according to the terminal identification information acquired from the sender address or a session variable.
The availability information transmission program then transmits an E-mail to the primary terminal 1. This transmission is done only when the availability information is “available”, that is, only when the available button 21 is clicked, in order to immediately inform the physician in charge that the expert-physician replies “available”. Hereinafter, this E-mail is referred as “availability mail”.
The support system of this embodiment comprises a primary transmitter to transmit the initial disease data to formally request provision of an opinion. This request is transmitted only to each secondary terminal 2 handled by each expert-physician having replied “available”. The primary transmitter is a means to make the initial disease data input at a primary terminal 1, make the primary terminal 1 transmit the input data to the communication server 3, and forward it to each secondary terminal having replied “available”. The initial disease data includes a disease image of the patient and the time it was taken.
More concretely, as components of the primary transmitter, the support system comprises the primary terminal 1, the communication server 3 and a primary transmission program installed on the communication server 3. A form file for displaying a form to transmit the initial disease data, hereinafter, “initial disease data transmission form”, is stored in the storage of the communication server 3. As shown in
What is major in the initial disease data is an image. In the example shown in
Although the file information of the image is automatically acquired as described, it also can be confirmed in advance. The image confirmation button 25 shown in
As shown in
The initial transmission program is executed by clicking the transmission button 26 shown in
In the example shown in
In this, the image displaying program makes an access to the EP-DBF, and acquires the information in the filed “Terminal Type”. After determining the compression level according to the terminal type and compressing the image file at the determined level, the image file is sent to the secondary terminal 2. The image file may be sent without any compression if the secondary terminal 2 is a desktop computer or workstation. Because the compression level is adequately chosen according the type of the secondary terminal 2, the image can be displayed in an optimal condition according to the performance of the secondary terminal 2. After displaying the image on the secondary terminal 2 as shown in
As shown on
Points featuring this embodiment in the image restructuring are that such a restructuring program can be executed by a secondary terminal 2 located outside the hospital, and that only an expert-physician having replied “available” is authorized to do such processing.
As shown in
In another case, the initial image may be a movie. That is, a movie may be displayed by clicking the image browsing button 41. In this case, the movie is not only one taken in the past, but may be a real time picture. For example, the output data of a continuing investigation device, such as electrocardiographic device, may be sent by a streaming transmission. For this, a streaming transmission program is installed on the communication server 3, which is executed by clicking the image browsing button 41. The streaming transmission of a movie is particularly desirable, considering that it is used in treating an emergency disease. A treatment option for a seriously ill emergency patient must be decided urgently. In this, if an expert-physician watches a real time diagnostic movie, he/she can provide an opinion on site, the probability that a more adequate treatment is carried out without being too late would increase. A movie may be directly included in the initial disease data mail.
Transmission of an opinion will be described next, returning to
In the image displaying forms shown in
As shown on
A form file for a form to display an opinion on a primary terminal 1 is stored in the storage of the communication server 3. In this embodiment, because the opinion is transmitted via E-mail, the form is a mail form. Hereinafter, this form is referred as “opinion displaying form”, and the mail is referred as “opinion mail”. After recording the information in each DBF as described, the secondary transmission program lays the opinion sent from the secondary terminal 2 in the opinion displaying form, and forwards it to the primary terminal 1 handled by the physician in charge, according to the in-hospital physician ID recorded in the temporary case DBF. The program is ended with this.
The opinion mail shown on
As shown on
In the example shown on
A form file for an integrated answer displaying form is stored in the storage of the communication server 3. In the inquiry result displaying form shown in
As shown on
The batch-type initial transmission program lays the initial disease data input in the initial disease data transmission form, and transmits it to the terminal addresses in order via E-mails. Those terminal addresses are of the secondary terminals 2 which have replied “available” for the case ID, and to which no initial disease data has been transmitted (i.e., the terminal addresses for which the field “Initial disease data Transmission Time” is null). By transmitting the E-mails to all the corresponding terminal addresses, the batch-type initial transmission program is ended.
In the batch-type initial disease data transmission as described, it may be possible to automatically capture the image file information as same as in the form for the immediate-type initial disease data transmission shown on
Integral display of opinions will be described next. As shown on
As understood from
A real-time communicator will be described next. The real-time communicator is what the support system of this embodiment comprises to carry out a real-time communication after the initial disease data is transmitted, making a group of the terminals 1, 2. The group is made of the primary terminal 1 having sent the inquiry information for a case, and all of the secondary terminals 2 having replied “available” to the inquiry information. The support system can choose to carry out the real-time communication by the real-time communicator when any one of the secondary terminal 2 transmits an opinion after the initial disease data are transmitted.
As shown on
The initial RTC program first creates a temporary database file for managing the real-time communication, hereinafter, “RTC-DBF”. The name of the RTC-DBF is given in a predetermined way using the case ID, for example, “10-a1111-rtc.dbf”. The initial RTC program next reads out the case ID from the session variable, and opens the temporary receiver DBF. Then the program reads out the information of the fields “EP ID”, “EP name”, “Terminal Address” and “Terminal Identification Information” in all the records in the temporary receiver DBF where the field “Availability” is the true value, and records it in each new record added in the RTC-DBF, i.e., copies the records. After copying all the records, the program adds another new record in the RTC-DBF, and records the information of the primary terminal 1 (i.e., terminal address or terminal identification information) therein. As a result, the terminal group is made of all the secondary terminals 2 having replied “available” for the case and the primary terminal 1 handled by the physician in charge for the case.
Afterward, the initial RTC program reads out a RTC mail form stored in the storage of the communication server 3, pastes the opinion (text) in the RTC mail form, and automatically forwards it to all the terminals 1, 2 of the group via E-mails. The RTC button 57 shown on

A progress information transmitter will be described next. The support system of this embodiment comprises the progress information transmitter to transmit progress information to each secondary terminal 2. “Progress information” means information on condition of a patient, additional test and investigation, diagnosis, or treatment after transmitting an initial disease data. As components of the progress information transmitter, the support system comprises the primary terminal 1, the communication server 3 and some programs installed in the communication server 3. One of the programs is the first progress information transmission program to make the progress information input, process the progress information displaying form, and distribute an alarm mail to each secondary terminal 2. Another one of the programs is the second progress information transmitting program to transmit the processed progress information displaying form, responding to an access from each secondary terminal 2.
Even after receiving the opinion transmitted, responding to the initial disease data, the patient's condition could change by the minutes and hours. An additional test and medication are often carried out if necessary. Therefore, the information about such subsequent progresses should be transmitted to the expert-physicians. The progress information transmitter is in consideration of this point.
Similar to the transmission of additional observations in transmitting the initial disease data, the progress information may be input at the primary terminal 1, and transmitted to each secondary terminal 2 via the communication server 3. Nevertheless, the support system of this embodiment comprises a special component, considering the object of this system, i.e., supporting an emergency patient treatment. That is, the support system comprises a component to include time information in the progress information, and transmits the progress information so that it is displayed with a time bar. The time bar is a line showing a time scale.
In the menu form shown on
When the image selection button is clicked, the first progress information transmission program captures an image taken subsequently, and lays it at a predetermined position in the progress information displaying form. In this, information of the time and date it was taken is also acquired from the PACS server 6 and laid in the progress information displaying form.
When the numerical data selecting button is clicked, the first progress information transmission program incorporates data directly from a monitoring device (e.g., blood pressure monitor) connected to the intranet 10, or inputs it on the primary terminal 1. The numerical data is laid at a predetermined position in the progress information displaying form. In this, the extraction time and date of the numerical data are acquired, and laid in the progress information displaying form.
When the medication selecting button is clicked, the first progress information transmission program makes the medication information (e.g., name and quantity of a administered medication, administration time and date) input on the primary terminal 1, and lays the input information at a predetermined position in the progress information displaying form.
Distribution of the progress information to each secondary terminal 2 is done by sending an E-mail from the communication server 3 to each secondary terminal 2 and embedding in the E-mail a command executing the progress information programs. Those E-mails urge the expert-physicians to download the progress information, by informing that it has been uploaded to the communication server 3. Those E-mails are hereinafter referred as “progress information reminder mails”. A form file for a progress information displaying form is stored in the storage of the communication server 3. The first progress information transmission program updates the progress information displaying form by laying therein the input progress information, stores the updated form file, and sends the progress information reminder mails for executing the second progress information transmission program. By this, the first progress information transmission program is ended.
On the progress information displaying form shown in
The processed progress information displaying form is stored in the storage of the communication server 3 under a filename using the case ID. In transmitting the progress information displaying form second time or more, the first progress information transmission program reads out the stored form and adds a new piece of progress information with a new balloon, and updates the form file. By the second progress information transmission program, the updated form is transmitted to the secondary terminal 2.
Recording of history information will be described next. The support system of this embodiment comprises a history recorder. As components of the history recorder, the support system comprises a recording server 5 and history information database file (hereinafter, “HI-DBF”) stored in a storage of the recording server 5. As shown in
The management ending program opens the temporary case DBF according to the input in-hospital physician ID, and displays a list of the information in the record(s) where the in-hospital physician ID is correspondent. This part is almost the same as on
The management ending program searches the temporary case DBF by using the case ID as search key, and cuts out the corresponding record. With that, all the information in the fields is stored to a memory variable, and the record is deleted from the temporary case DBF. Then the program adds a new record in the HI-DBF on the recording server 5, reads out the information from the memory variable, and records it in the added new record of the HI-DBF. The structure of the HI-DBF may be the same as of temporary case DBF.
Afterward, the management ending program cuts out the temporary receiver DBF for the case, according to the case ID. After storing the temporary receiver DBF to a memory variable, the program deletes it from the storage of the communication server 3. Then the program reads out the temporary receiver DBF from the memory variable, and stores it in the storage of the recording server 5. By this, the program is ended. The files in the storage of the recording server 5 are preserved permanently or for a predetermined long term. The recording server 5 has the role of the preservation place of the system usage history.
In the described support system of this embodiment, an opinion is preferably transmitted with an digital signature of the expert-physician who is sending it. E-mail transmissions with digital signatures are possible as regular functions in almost all mailers for desktop or notebook computers. Therefore, if a secondary terminal 2 is a desktop or notebook computer, it is utilized. To expert-physicians, it is requested in advance to transmit opinions with digital signatures.
As for mobile-type terminals, there are few types having functions of sending E-mails with digital signatures. The support system of this embodiment, therefore, comprises a special contrivance where retransmissions of opinions with digital signatures are requested to expert-physicians later on. As shown in
A transmission button is provided in the signature request form. The acquired mail address is embedded in this transmission button. The signature request form includes a message that retransmission of the opinion, which is displayed for confirmation, with a digital signature is requested. By clicking the transmission button, the signature request form is transmitted to the mail addresses via E-mails. The expert-physicians reply to it, retransmitting the opinions with digital signatures. The communication server 3 comprises a program to check whether a digital signature is attached to an E-mail (e.g., the opinion mail and the above reply mail) transmitted from a secondary terminal 2, according to the header information of the E-mail. If a digital signature is attached, the program acquires the digital signature information therefrom and preserves it. The digital signature information can be preserved in a field named “Digital Signature Information”, which is provided in, for example, the temporary receiver DBF. Otherwise it can be preserved in another database file. The digital signature information, which includes a digital signature itself and information thereof, is preserved in the HI-DBF in the recordation server 5 as well as the opinions.
An alarmer will be described next. The support system of this embodiment comprises the alarmer to generating alarms when the initial disease data is transmitted from a primary terminal 1. The alarms are to inform the expert-physicians that the initial disease data has been transmitted, and prompts them to transmit their opinions. Because transmissions of the opinions are for a treatment of an emergency patient, those are is very urgent. If receipts of the initial disease data are not recognized, the opinions could not reach at adequate timings, resulting in that those could not be referred in deciding a treatment plan. Considering this, the support system comprises the alarmer. The alarmer is a means to generating alarms made of sound, light, vibration or any combination thereof.
In the support system of this embodiment, as described, the inquiry information and initial disease data are transmitted via E-mails. Therefore, the alarmer is the means to give notice of arrivals of the E-mails to the expert-physicians. Because almost all mailers currently used have functions of alarming arrivals of E-mails, those functions are used for the alarmer in this embodiment. It is requested in advance to the expert-physicians to preset the secondary terminals 2 so that the alarming functions can work.
If the inquiry information and initial disease data are not transmitted via E-mails, the alarmer has to be modified. For example, if the system is modified to be one where a secondary terminal 2 actively accesses the communication server 3 and acquires the initial disease data after it is transmitted from the primary terminal 1, the alarmer has to prompt the secondary terminal 2 to access the communication server 3. As an example for this, the alarmer may make a single ring call to each cell phone held by each expert-physician. That is, the alarm makes a call of single or several rings to each cell phone from a phone number allocated to this system. The calls are done under the condition that the caller number notification is valid, so that the caller number can be known as of the support system at the secondary terminals 2. Each cell phone number of each expert-physician is registered in the EP-DBF, and a program to make such calls in order is installed in the communication server 3.
In the described embodiment, the inquiry information and initial disease data may be transmitted via downloads from the communication server 3. In this case, an E-mail including a brief text as shown in
By the above-described support system of this embodiment, the initial disease data including an image is transmitted to multiple expert-physicians with the reply period thereto. Then the opinions based on reviewing the initial disease data are transmitted from the expert-physicians. Therefore, the physician in charge can establish a diagnosis and decide a treatment plan referring to the opinions. Accordingly, the probability that a more adequate treatment is performed increases, compared to the case the physician in charge does all that alone.
In addition, the inquiry information is transmitted to the expert-physicians before transmitting the initial disease data. The initial disease data is transmitted to only the expert-physicians who have replied that the opinion can be provided. Therefore, the initial disease data are not transmitted wastefully and indiscreetly to expert-physicians who cannot respond to. On the side of the expert-physicians, there is no uneasiness, because the initial disease data for a case to which he/she cannot commit is not reaching him/her. Because the initial disease data includes a diagnostic image, it is preferable to transmit it only to the expert-physicians having replied “available”, in view of the privacy information protection.
The support system of this embodiment can select the expert-physicians with a specific level of specialization, and transmit the initial disease data only to them. Therefore, provisions of opinions can be requested only to those expert-physicians with the adequate specialization level, considering the particularity of a disease, difficulty of diagnosis and treatment, and the like. Accordingly, it leads to obtaining much more adequate opinions, which contributes to a much more adequate treatment.
Moreover, because the support system of this embodiment comprises the real-time communicator, it is possible that many of the expert-physicians provide their comments on one emergency disease or one opinion, thereby making a discussion. Therefore, it is possible to reach a more adequate conclusion by accumulating many comments and opinions on the disease, which enables a more adequate treatment.
Because the support system of this embodiment comprises the progress information transmitter, it is possible to request an additional opinion depending on a situation after transmitting the initial disease data. Therefore, a more adequate treatment is enabled in this respect. In this, because the progress information is displayed time-related on a secondary terminal 2 with the time bar showing all events in the established time-frame, it is possible for the expert-physicians to know easily the evolution of diagnosis and treatment in time. Therefore, opinions can be provided with more adequate timings in the treatment of the emergency disease, which is the “battle against time”.
Moreover, the support system of this embodiment comprises the image restructurer which enables the expert-physicians to freely restructure an image by themselves. Therefore, they can give their opinions more adequately reviewing the restructured image. In the HI-DBF on the recording server 5, this support system records and preserves the fact that opinions were requested transmitting an initial disease data as well as provided opinion(s). The preserved information can be utilized later on as evidences showing a treatment was done adequately. That is, if it is questioned whether the diagnosis and treatment plan were adequate (e.g., if any malpractice lawsuit is brought), the hospital can reply by asserting that opinions were requested appropriately to the expert-physicians on the basis of the initial disease data, and that the diagnosis and treatment were accomplished according to the provided opinion(s). In this defense, because this system receives an opinion with a digital signature, and the opinion is preserved in the history information file with the digital signature, credibility i.e., evidential value, for the receipt and contents of the opinion can be enhanced. The system has advantage in this respect.
In the described support system, an image transmitted form the communication server 3 may be a movie taken during a surgery. For example, a movie taken during a surgery could be transmitted to the secondary terminals 2 in real time as the progress information. The streaming distribution technique is used for this real time transmission. Otherwise an Internet video phone service can be used. Therefore, detailed description is omitted. A form in which a surgical movie is displayed may include a command button to transmit an opinion. An expert-physician clicks the button and transmits the opinion when he/she notices anything to comment on the movie. A surgical movie may be transmitted as the initial disease data. For example, the inquiry information is transmitted to expert-physicians when starting a surgery. In this inquiry, it is informed in advance that a surgical movie will be transmitted, and each expert-physician is asked to provide his/her opinion while watching the movie.
In the described support system, it is preferable that the progress information is transmitted not only to the secondary terminals 2 but to other primary terminals 1 in the hospital. In a situation where several physicians and nurses are in charge of an emergency disease treatment as a team, for example, each member of the team carries a mobile-type primary terminal 1. When any progress information takes place, it is transmitted to each primary terminal 1 in the team immediately. By this, the progress information can be shared by all members of the team in real time. This enables that the diagnosis and treatment of the emergency disease are performed faster and more effectively.
In the description of this embodiment, although cerebrovascular diseases such as cerebral infarction and cerebral hemorrhage were taken as examples, the invention can be used for supporting treatments of diseases in other clinical fields. For example, the invention can be used for cardiovascular diseases such as myocardial infarction and aortic aneurysm. The invention also can be used for an emergency such as injury (e.g., by a traffic accident), and for an obstetric emergency, such as imminent premature birth and perinatal cerebral hemorrhage.
