This invention generally relates to training support systems and, more particularly, to training support systems based on user behavior.
Medical personnel or the like frequently interact with software and various medical devices. Learning how these medical personnel interact with these software platforms and devices, as well as their expectations of new technologies, may be helpful in creating more effective software platforms and medical devices.
It is often difficult, however, to gather helpful information regarding these medical personnel interactions. Current techniques to gather this type of information may involve interviews with medical personnel. However, conducting these interviews may be time consuming, labor intensive, and takes medical personnel away from their medical duties.
There are also typically variations in usage among personnel employed by different healthcare institutions and treating different kinds of patients. Collaborating with or interviewing a subgroup of professionals can yield biased results that are not representative of all healthcare institutions and medical personnel. On the other hand, interviewing larger groups of medical personnel and tracking their daily workflows may be difficult if not impossible.
Even with close collaboration, efficient communication with medical personnel and healthcare institutions still cannot be guaranteed. For example, existing clinical decision support (CDS) tools inevitably generate noise or redundant information that can be distracting rather than helpful. Also, there may be areas not recognized (i.e., not currently monitored) where CDS tools could intervene to support patient care.
A need exists, therefore, for improved clinical decision support systems.

Accordingly, the present disclosure is intended to be illustrative, and not limiting, of the scope of the concepts discussed herein.
Having knowledge of how medical personnel interact with medical devices and software may help design more effective and user-friendly medical devices and software. This may in turn lead to higher quality patient care. A variety of patient care-related applications may benefit from the features of the invention.
For example, deterioration detection tools typically monitor patients' vital signs and other physiological parameters, calculate a score using the monitored parameters, and trigger an alarm if the score exceeds a certain threshold. Having an in-depth understanding of the medical problem and the healthcare institution workflow (e.g., how medical personnel react to certain patient symptoms and patient physiology) may also be used to improve deterioration detection.
Alarm systems are another important component of deterioration detection. These systems may generate a score based on physiological parameters, and an indicator (e.g., an alarm) may be issued if the score is above (or below) a predetermined threshold. For system designers, it may be important to know how to balance the sensitivity and specificity of the alarm system. Having an in-depth understanding of the users' experiences, their tolerance to false alarms, and their preferences as to how the system should be integrated into their workflow may therefore improve alarm management.
Another application may involve the integration of multiple deterioration detection methods to provide decision and navigation support (e.g., steps to be taken by medical personnel). For system designers, it may be important to know how medical personnel interact with each other, the particular tests they order for particular medical conditions, the medications they typically prescribe for certain conditions, and the like.
Features of the present invention therefore analyze individual users' behavior as it relates to multiple medical devices and/or software platforms. The ways users respond to alarms, how they treat certain patient conditions, and their sequential movement across multiple platforms all reflect their medical expertise. Mining this behavior data, along with patients' physiological data, may lead to a better understanding of users' medical knowledge which can be leveraged to train new CDS methods.
It is also contemplated that embodiments of the present invention may be used in other types of applications, such as those in the military, retail, e-commerce, finance, transportation, or any type of data-driven application that may benefit from the features of the present invention. For the sake of simplicity, however, the features of the present invention will be described as being implemented in healthcare institutions. The term “user” may refer to any type of medical personnel such as doctors, physicians, nurses, physician assistants, caregivers, receptionists, or any other interested party providing healthcare.
Information regarding the user's behavior and actions while interacting with the I/O devices 102 may be stored in at least one records database 106 and analyzed by an analyzer module 108 when appropriate. Information regarding the user's behavior may also be communicated directly to the analyzer module 108.
Information regarding patient physiological parameters may be stored in at least one parameter database 110. The integrator module 112 may integrate information regarding thousands of users' behavior with patients' physiological parameters from the parameter database 110.
Outputs of the integrator module 112 may then be used train various CDS platforms, such as, e.g., a deterioration detection module 114, an alarm management module 116, a decision and navigation support module 118, etc.
The I/O devices 102 illustrated in
With continued reference to
The user tracker module 104 may be any configured processor or the like that can monitor, record, and communicate information regarding the user's behavior. The user tracker module 104 may, for example, monitor medical interventions taken by the user(s). If the user is using a software-related platform, for example, the user tracker module 104 may monitor the buttons or tabs clicked by the user, the pages viewed, the amount of time the user remains on a particular page, messages sent and received regarding a patient, etc.
Information regarding the user's behavior may be stored in at least one records database 106 until ready for analysis by the analyzer module 108. Or, information regarding the user's behavior may be communicated directly to the analyzer module 108 by the user tracker module 104.
The analyzer module 108 may be configured to perform calculations or other processes on the data regarding the user's behavior. In some embodiments, the analyzer module 108 may be configured to calculate various derivatives of the measured behavioral data, including but not limited to simple averages (i.e., a mean(s)), weighted averages, standard deviations, etc. In some embodiments, the analyzer module 108 may be implemented as a single pole filter, a multipole filter, a Kalman filter, etc.
The system 100 may also include at least one parameter database 110. The parameter database 110 may store information relating to physiological parameters of thousands of patients. This information may relate to patient medical history, patient test results, vital sign measurements, etc.
The parameter database 110 may also be in communication with the analyzer module 108. The analyzer module 108 may therefore process or otherwise analyze parameter-related information prior to integration by the integrator module 112. For example, in some embodiments, the analyzer module 108 may be configured to calculate various derivatives of the parameter-related information, including but not limited to simple averages (i.e., a mean(s)), weighted averages, standard deviations, etc.
The output(s) of the analyzer module 108 (or databases) may be communicated to the integrator module 112. The integrator module 112 may integrate the behavior-related information with parameter-related information to evaluate or otherwise train CDS tools. That is, the modules and databases 104-12 can be implemented in or otherwise used to train CDS tools such as the deterioration detection module 114, the alarm management module 116, and/or the decision and navigation support module 118.
The user tracker module 104 may monitor or otherwise keep track of the user's behavior when they are treating a patient. As mentioned previously, this may include medical orders placed by the user and/or other user actions interacting with various platforms such as EMR and various CDS tools.
For a particular patient, at any given episode t0 the analyzer module 108 analyzes the actions taken by the user(s) (e.g., physicians, nurses, or other medical personnel) in a small time window [t0−δ, t0+δ] (Step 300). In this particular embodiment, δ represents the time window preceding/following t0 in which we assume a user takes actions to treat the patient's condition. These actions could be reviewing certain information, prescribing medications, conducting certain procedures or interventions, or placing any comprehensive medical orders. The variable δ may of course vary based on different applications (and/or may of course vary depending on the particular episode, patient, or condition).
Based on a set of (e.g., predetermined) criteria, the analyzer module 108 may determine if the collection of actions taken in the window [t0−δ, t0+δ] indicate whether a particular patient is at risk of deterioration (or some other health-related condition, depending on the application) at t0 (Step 304). This determination may result in a “yes” or “no” determination, and may be referred to as behavior-based risk categorization. That is, the categorization is based on the user's behavior.
The integrator module 112 may then obtain physiological parameters in a time window before t0 [t0−Δt, t0] from the parameter database 110 (Step 308). Δt represents the time window preceding t0 in which vital signs and other parameters are measured that may be predictive of the patient's condition at t0. These physiological parameters may be gathered by a plurality of vital sign sensors (not shown) and, collectively, may relate to physiological parameters of thousands of patients over thousands of episodes. The variable Δt may of course vary depending on the application (and/or depending on the particular episode). The integrator module 112 could be programmed to utilize various types of data mining techniques, such as regression, decision trees, random forest, vector support machine, Bayesian methods, or the like.
The risk categorization made by the analyzer module 108 is used as ground truth to separate patients into a positive group (patients with a particular condition) and a control group (patients without the particular condition) (Step 312). The integrator module 112 integrates the risk categorization and the information regarding the physiological parameters for future iterations of the deterioration detection module 114 (Step 316). The integrator module 112 could be programmed to utilize various types of data mining techniques, such as regression, decision trees, random forest, vector support machine, and Bayesian methods.
For example, the deterioration detection module 114 can be configured to target specific user actions so that the outcome of the system could be an algorithm trained to use a combination of physiological parameters to detect a certain condition (e.g., respiratory illness). Or, the deterioration detection module 114 can be configured to target more actions, so the outcome of the system can be an algorithm used to detect general deteriorations.
For this method 400, assume at least a one patient is experiencing a health condition-related episode. Step 402 involves retrieving records of medical personnel actions preceding and following the episode from at least one records database. As stated previously, these actions may include tests performed by the medical personnel, notes taken by the medical personnel, procedures or interventions conducted by the medical personnel, etc.
Step 404 involves using at least some of the retrieved action records to determine whether the condition of the at least one patient is at risk of deterioration. For example, if these records show that medical personnel ordered a series of medications and/or performed certain procedures, it may be determined that the condition of the at least one patient is at risk of deterioration. This step may result in a “yes” or “no” determination.
Step 406 relates to at least one other patient experiencing a similar episode. Step 406 involves retrieving records of physiological parameters preceding and following the similar episode for the at least one other patient from at least one parameter database 110. These may be certain vital sign measurements, for example, and may vary depending on the application.
Step 408 relates to the at least one patient of step 406. Step 408 involves categorizing this patient into a control group or a positive group using at least some of the retrieved action records. Categorizing the patient into the positive group may indicate the condition of the patient is at risk of deterioration. Categorizing the patient into the control group may indicate the condition of the patient is not at risk of deterioration.
Step 410 involves training at least one algorithm for deterioration detection utilizing the retrieved physiological parameters for at least one patient in the positive group. This could be an algorithm trained to use a combination of physiological parameters to detect a certain condition, for example, respiratory illness.
Alarm management strategies are an important component of deterioration detection and providing healthcare. As discussed previously, deterioration detection models may often generate a score based on patients' physiological parameters. Very essential to these types of models are alarm management strategies that determine whether to present the score as a risk indicator or an alarm. Additionally, the sensitivity and specificity of the alarm must be appropriately tailored to best serve the users. Variables in the alarm management system may include the user's work patterns, their tolerance to false alarms, and how they would like the alarm management system to be integrated into their workflow.
Presently, medical devices and software can generate various types of alarms in healthcare institutions. These alerts may be issued if, for example, it is determined that a patient has a health-related condition. Features of the present invention may monitor and record how users respond to these alarms and their sequential actions.
When an alarm is signaled by a device or other software, the user tracker module 104 may record when (i.e., t0) and how the user responds to the alarm. For example, the user may accept or dismiss the alarm.
The alarm(s) may be communicated in a variety of ways. For example, if the user is carrying a mobile device such as device 102b of
A series of criteria may be programmed to determine if the collection of actions taken in the time window [t0, t+δ] indicate if the patient is at risk of deterioration (or some other health-related condition) (Step 504). For example, ordering a certain dosage of a particular medication may indicate that the patient is at risk. On the other hand, conducting no further tests or ordering no medications may indicate that the patient is not at risk.
A false negative occurs when no alarm is signaled but there are medical interventions that indicate risk. A true negative occurs when no alarm is signaled and there are no actions that indicate or otherwise suggest there is a risk.
As in the deterioration detection module 114, the integrator module 112 may obtain physiological parameters in a time window before t0 [t0−Δt, t0] (Step 512). Collectively, data from thousands of episodes of thousands of patients may be integrated.
In this application, the alarm management module 116 may use the behavior-based categorization as ground truth to separate alarms into different categories (i.e., true positive, false positive, true negative, and false negative). The alarm management module 116 also uses the physiological parameters as input to train new alarm management strategies.
As seen in
Step 604 involves using at least some of the retrieved action records to determine whether the condition of the at least one patient is at risk of deterioration. This may be determined by the analyzer module 108 of
Step 606 involves, for at least one other patient that experiences a similar indicator, retrieving records of physiological parameters preceding and following the similar indicator from at least one parameter database. These records of physiological parameters may be obtained from the parameter database 110 of
Step 608 involves categorizing the similar indicator as a true positive, false positive, true negative, or false negative using at least some of the retrieved action records. This categorization may be made using the analyzer module 108 of
Step 610 involves training at least one algorithm utilizing the categorized indicator.
This may be accomplished by the integrator module 112 after integrating information regarding the categorization and the physiological parameters.
In this embodiment, there are no alarms in the form of sound or light. However, the non-alarm indicator may be displayed as a curve on a screen, for example. For example, the various I/O devices 102 of
As with the previously-discussed applications, the system tracks users' actions in a time window [t0, t0+δ] after the non-alarm indicator passes a certain threshold. Similar to the embodiment illustrated in
This application can also learn more from users' specific behaviors. Non-alarm indicators are often based on continuous scores and do not force users to take action. The users' behavior therefore may reflect their judgment as to when is the best time for medical intervention.
For example, information such as the exact score when users start to take actions, along with the difference between the time when the score enters a certain “zone” and the time when users intervene may be analyzed. These parameters may be used to train a new non-alarm indicator and a new set of alarm management strategies. For example, an alarm may be communicated only when a score reaches a user-specific score (i.e., a score at which point a specific user normally takes action). These features may also be implemented in the applications and methods illustrated in
A third application is behavior-trained decision and navigation support. In this application the system 100 may again track users' movement across multiple platforms, such as EMR, imaging software, and various other CDS tools. The information obtained by tracking users' movements may be used to train the system 100 to assist in future patient treatment episodes.
They type of information analyzed may of course depend on the specific page the user is viewing and interacting with. For example, the user tracker module 104 may track diagnosis key words when physicians review reports 808 (e.g., progress reports, imaging reports). It may also track key values and trends of lab tests 812 when the user is viewing the EMR, vital signs and trends 816 when the user views/interacts with the vital sign tab, and combinations of medications 820 when the user views/interacts with the medication administration record tab.
The user tracker module 104 may also track medical orders placed by users 824, and the analyzer module 108 may categorize the orders by behavior-based risk categorization 828. Different types of information, collectively, from thousands of patients and users may be integrated by the integrator module 112. The system 100 thus learns the mutual relationship (e.g., timing logic relationship, physiological relationship, etc.) between various types of information and may link them to train a new decision and navigation support tool. This, among other things, may more quickly provide users with relevant information and suggest possible courses of action.
Step 904 involves providing guidance to medical personnel using at least some of the retrieved action records. This guidance may be presented to users or other interested parties via interfaces of devices 102 of
Section 1004 essentially represents information extracted by the various modules of the system 100 during the steps outlined in section 1002. In other words, the system 100 learns from users' actions from this particular scenario outlined in section 1002. This section 1004 summarizes, e.g., key words of symptoms, key words of history, actions taken, and types of imaging viewed.
Section 1006 illustrates the outcome of the decision and navigation support module 118. Specifically, section 1006 outlines a series of automated steps that assist users in treating a patient in future patient-treatment episodes. For example, say a user (nurse) notices a patient having several symptoms and typed “shortness of breath” and “chest pain” into an I/O device 102. The decision and navigation support module 118 (i.e., a CDS platform) may recognize these symptoms as indicative of a potentially serious condition that requires further attention based on the scenario outlined in section 1002.
The decision and navigation support module 118 may then automatically pull the physician's number and present a “call” button. The nurse can then quickly call the physician and update the physician regarding the observed symptoms. The decision and navigation support module 118 may also present recommendations of a 12-lead EKG via an interface of an I/O device 102, as these were the same orders that the physician made in 1002. The nurse or physician can then place the order by just one click.
When the physician opens this particular patient's EMR, a navigation bar may present the physician with tabs so the physician may quickly access to Labs, Vitals, Meds, or the like. Any test results may be uploaded (e.g., manually or automatically) to the patient's EMR, and the decision and navigation support module 118 may recommend several new medical interventions. The decision and navigation support module 118 may suggest that the physician place the patient on different medications, for example. The physician can choose form the list of suggestions depending on their judgment of the patient's condition.
The methods, systems, and devices discussed above are examples. Various configurations may omit, substitute, or add various procedures or components as appropriate. For instance, in alternative configurations, the methods may be performed in an order different from that described, and that various steps may be added, omitted, or combined. Also, features described with respect to certain configurations may be combined in various other configurations. Different aspects and elements of the configurations may be combined in a similar manner. Also, technology evolves and, thus, many of the elements are examples and do not limit the scope of the disclosure or claims.
Embodiments of the present disclosure, for example, are described above with reference to block diagrams and/or operational illustrations of methods, systems, and computer program products according to embodiments of the present disclosure. The functions/acts noted in the blocks may occur out of the order as shown in any flowchart. For example, two blocks shown in succession may in fact be executed substantially concurrent or the blocks may sometimes be executed in the reverse order, depending upon the functionality/acts involved. Additionally, or alternatively, not all of the blocks shown in any flowchart need to be performed and/or executed. For example, if a given flowchart has five blocks containing functions/acts, it may be the case that only three of the five blocks are performed and/or executed. In this example, any of the three of the five blocks may be performed and/or executed.
A statement that a value exceeds (or is more than) a first threshold value is equivalent to a statement that the value meets or exceeds a second threshold value that is slightly greater than the first threshold value, e.g., the second threshold value being one value higher than the first threshold value in the resolution of a relevant system. A statement that a value is less than (or is within) a first threshold value is equivalent to a statement that the value is less than or equal to a second threshold value that is slightly lower than the first threshold value, e.g., the second threshold value being one value lower than the first threshold value in the resolution of the relevant system.
Specific details are given in the description to provide a thorough understanding of example configurations (including implementations). However, configurations may be practiced without these specific details. For example, well-known circuits, processes, algorithms, structures, and techniques have been shown without unnecessary detail in order to avoid obscuring the configurations. This description provides example configurations only, and does not limit the scope, applicability, or configurations of the claims. Rather, the preceding description of the configurations will provide those skilled in the art with an enabling description for implementing described techniques. Various changes may be made in the function and arrangement of elements without departing from the spirit or scope of the disclosure.
Having described several example configurations, various modifications, alternative constructions, and equivalents may be used without departing from the spirit of the disclosure. For example, the above elements may be components of a larger system, wherein other rules may take precedence over or otherwise modify the application of various implementations or techniques of the present disclosure. Also, a number of steps may be undertaken before, during, or after the above elements are considered.
