WIRELESS MOBILE DEVICE ACCESS TO NURSE CALL SYSTEM ALERTS AND DATA

BACKGROUND

The present disclosure relates to healthcare information systems and particularly, to healthcare information systems in which caregivers carry wireless mobile devices such as mobile phones. More particularly, the present disclosure relates to healthcare information systems having nurse call system connectivity to wireless mobile devices carried by caregivers.

Nurse call systems that send messages regarding nurse calls and alerts to wireless devices carried by caregivers are known. For example, the COMLINX® nurse call system, available from Hill-Rom Company, Inc., was operable to send nurse calls and alert messages to pagers carried by caregivers. See, for example, U.S. Pat. No. 6,462,656 in this regard. U.S. Pat. No. 5,319,355 also contemplates sending nurse calls to pagers carried by caregivers. U.S. Pat. No. 7,319,386 contemplates a system in which nurse calls and alerts are sent to various wireless communication devices such as pagers, VOCERA® badges, and telephone handsets, including ASCOM® or SPECTRALINK® handsets, via infrastructure located within a healthcare facility. U.S. Pat. No. 11,257,588 discloses a system of a healthcare facility in which nurse calls and alert messages are sent to touch screen based mobile phones of caregivers using infrastructure of the healthcare facility.

In the modern-day healthcare setting, caregivers oftentimes carry more sophisticated wireless mobile devices, such as mobile phones (aka “smart phones”), during their shifts. These more modern mobile phones are touch screen based and have a large amount of computing power for running a multitude of software applications. However, a full integration between nurse call systems and these types of modern day mobile phones, such as iOS™ and ANDROID™ mobile phones, has not yet been satisfactorily implemented. What is needed therefore, is a software application and/or an overall infrastructure system that makes the full scope of alert and status data resident in a nurse call system available on caregivers' wireless mobile devices, such as modern-day smart phones, while at the same time providing integration with other healthcare system and third party supplier functionality.

DETAILED DESCRIPTION

A healthcare information system 10 according to the present disclosure includes a nurse call system 12 that is communicatively coupled to connected service architecture (CSA) 14 which is, in turn, communicatively coupled to a mobile app gateway 16 as shown in FIG. 1. Mobile app gateway 16 is communicatively coupled to a plurality of wireless mobile devices, illustratively mobile phones 18, that are carried by caregivers in a health care facility but only one mobile phone 18 is illustrated in FIG. 1 for the sake of economy of illustration. Each mobile phone 18 receives alerts, nurse calls, and other messages from nurse call system 12 via first path that includes the CSA 14 and via a second path that excludes the CSA 14.

Still referring to FIG. 1, nurse call system 12 communicates with mobile app gateway 16 by way of a hypertext transfer protocol secure (HTTPS) link or infrastructure 20. The HTTPS link sends encrypted messages from nurse call system 12 to mobile app gateway 16 which, in turn, sends encrypted messages by way of HTTPS WebSocket Secure (wss) links or infrastructure 22 to mobile phones 18 assigned to the rooms or patients from which the messages originated. More particularly, a nurse call application services portion 24 of nurse call system 12 communicates via link 20 with a nurse call interface 26 of mobile app gateway.

Nurse call system 12 also includes applications or services for handling action requests 28 which are preconfigured calls that caregivers can use to alert other staff of situations that require their attention; staff key performance indicators (KPI's) 30 which are metrics calculated for staff as it pertains to their job duties; and staff/asset locations 32 which involves receiving location data from a locating system 34 to determine the whereabouts of staff and assets within the healthcare facility. The locating system 34 includes locating tags 36 that are worn by caregivers and other staff and/or that are attached to equipment so that locating data transmitted from the tags and received by receivers at fixed locations in the healthcare facility can be mapped to locations by a locating server of the locating system 34. The locating system 34 and nurse call system are communicatively coupled by an Ethernet link or infrastructure 38.

Further applications or services of nurse call system 12 include reminders 40 which is a microservice that manages nurse call reminders such as rounding, turns due, medication due, temperature check due, and the like; and patient safety 42 which is a microservice that monitors nurse call states and generates alerts pertaining to patient safety. Such patient safety alerts include, for example, one or more bed siderails being lowered, a patient getting out of bed or moving toward getting out of bed, an upper frame of a patient bed being moved out of lowest position, and bed caster brakes being unbraked. Another application or service of nurse call system 12 is a session initiation protocol (SIP) server application 44 which is a service that manages voice communications between staff and patients or between staff members. In some embodiments, the SIP server application 44 uses FREESWITCH™ open source software.

Nurse call system 12 also includes a message bus service or application 46 which is an event bus used to announce changes of interest to subscribing clients and is used for asynchronous passing of messages between service applications. Message bus 46 of nurse call system 12 is communicatively coupled to a message bus 48 of the CSA 14 by way of a bidirectional communication link or infrastructure 50. Nurse call system 12 further includes a CSA integration service 52 which synchronizes nurse call data with the CSA 14. This enables the CSA 14 to replicate the nurse call data within a proxy server of the CSA 14. CSA integration service 52 is communicatively coupled to the CSA 14 by way of a bidirectional communication link 54. In general, each of the applications or services of nurse call system 12 are executed in software stored in memory of one or more nurse call servers of nurse call system 12.

In addition to message bus 48, CSA 14 has applications or services including a real-time communications (RTC) service 56 which enables voice and chat communications and that is communicatively coupled to SIP server application 44 by way of a bidirectional communication link 58; an alert manager 60 which is a service that handles alerts according to the Integrating the Healthcare Enterprise (IHE) protocol and routes the IHE alerts to the intended recipients; and a tenant service 62 which is a service responsible for managing information between multiple customer locations. CSA 14 also has a directory 64 which, in turn, has sub-directories for patients 66 (e.g., data pertaining to patient name, date of birth, risks, etc.), practitioners 68 (e.g., data to caregivers and other staff), assignments 70 (e.g., mapping between staff, patients, roles, and wireless devices 18), locations 72 (e.g., organizational units, such as division, campus, nursing units, and rooms configured for a healthcare facility); beds 74 (e.g., data pertaining to patient beds); and roles 76 (e.g., job functions that are assigned to practitioners).

With continued reference to FIG. 1, system 10 further includes a digital health platform 78, such as the Baxter Digital Health Platform available from Baxter International Inc. of Deerfield, Illinois, U.S.A. Digital health platform 78 includes an authentication application or service 80 which is responsible for authenticating login clients by verifying credentials against an identity provider 82 which is communicatively coupled to authentication application 80 via a bidirectional communication link 84. Authentication application 80 is also communicatively coupled to each mobile phone 18 by way of bidirectional HTTPS links or infrastructure 86. Additionally, in the illustrative example, digital health platform 78 is communicatively coupled to CSA 14 by a unidirectional communication link 85 and to nurse call system 12 by a unidirectional communication link 87. CSA 14 and digital health platform 78 are located geographically distant from the healthcare facility at one or more third party facilities in the illustrative example.

Referring once again to CSA 14, the RTC service 56 is communicatively coupled to each mobile phone 18 by way of bidirectional HTTPS wss links or infrastructure 88. As shown in FIG. 1, nurse call interface 26 of mobile app gateway 16 is communicatively coupled to message bus 48 of CSA 14 by way of an Advanced Message Queuing Protocol Secure (AMPQS) link or infrastructure 90. Furthermore, message bus 48 of CSA 14 is communicatively coupled to a core interface 92 by another AMPQS link or infrastructure 94. Links 90, 94 are unidirectional in that link 90 has messages going from nurse call interface 26 of mobile app gateway 16 to message bus 48 of CSA 14 whereas link 94 has messages going from message bus 48 of CSA 14 to core interface 92 of mobile app gateway 16. CSA 14 further has a GRAPHQL™ application or service 96 which is communicatively coupled to core interface 92 of mobile app gateway 16 via a bidirectional HTTPS link or infrastructure 98. GRAPHQL™ application 96 enables mobile app gateway 16 to access the CSA services using an open source query language protocol. In general, each of the applications or services of CSA 14 are executed in software stored in memory of one or more CSA servers of CSA 14.

Still referring to FIG. 1, mobile app gateway 16 includes an alert communicator application or service 100 which is a service that receives IHE alert dissemination messages from the alert manager 60 of CSA 14 and sends dissemination alert status messages to the alert manager 60. The alert communicator service 100 also forwards and receives dissemination alert status messages to and from the mobile phones 18. Mobile app gateway 16 also has a preferences/user management application or service 102 in which preferences are settings for the mobile applications of the various mobile phones 18 of caregivers and other staff that are configured for logged-in staff and in which user management handles the login process and manages authentication and authorization. Mobile app gateway 16 further includes a user satisfaction application or service 104 which is a microservice responsible for managing data collected from user (e.g., caregivers and other staff) feedback.

Mobile app gateway 16 includes a configuration service or application which is a web application used to configure settings for the mobile application of each mobile phone 18. In this regard a configuration computer 108 is coupled to mobile app gateway 16 by way of a bidirectional HTTPS link or infrastructure 110 and executes another configuration application to enable a user, such as an administrator, to configure the settings for the mobile application of mobile phone 18. Mobile app gateway 16 also includes a GRAPHQL™ service or application 112 that is used to send GRAPHQL open source query language messages to CSA 14. Illustrative mobile app gateway 16 additionally has a push notification service or application 114 which is a microservice used to initiate push notification requests to each mobile phone, which may be an iOS™ or ANDROID™ mobile device, for example. In general, each of the applications or services of mobile app gateway 16 are executed in software stored in memory of one or more gateway servers of mobile app gateway 16. Mobile app gateway 16 is located at a healthcare facility in some embodiments and is located geographically distant from the healthcare facility at a third party facility in other embodiments.

Push notifications are sent from service 114 of mobile app gateway to a push notification server 116 via a unidirectional HTTPS link or infrastructure 118. Push notification server 116 has software for implementing APPLE™ push notifications (APNs) 120 and FIREBASE™ cloud messaging (FCM) 122. APNs 120 are the only currently available means of delivering asynchronous events to an iOS-based application and FCM 122 is the only currently available means of delivering asynchronous events to an ANDROID-based application. APNs 120 and FCM 122 are used to wake the mobile application of the mobile phones 18 as part of the initiation of voice communication over SIP in addition to event notifications related to alert request status and other events. Push notification server 116 is communicatively coupled to each mobile phone 18 via unidirectional HTTPS links or infrastructure 124.

As shown in FIG. 1, system 10 optionally may include one or more products analytics servers 126 which implements a third party service that is used to track users' interactions with the mobile applications of the mobile phones such as screen views, button clicks, usage of other user inputs, etc. Server 126 communicates with the mobile phones 18 by way of HTTPS links or infrastructure 128. Illustrative system 10 further includes one or more mobile device management (MDM) servers 130 which are locally hosted systems at healthcare facilities and which are used to provide a reference version of the mobile application for mobile phones 18 along with configuration information required for use of mobile phones 18 in the facility. Configuration information includes, for example, the server and port associated with the reverse proxy. The one or more MDM servers 130 communicate with mobile phones 18 by way of unidirectional HTTPS links or infrastructure 132.

The HIPAA compliant format is, for each patient, the first two letters of the patient's last name, a set of ellipses, and the first letter of the patient's first name (e.g., in the last row of screen shot 134, the patient's name is shown as “Mi . . . M”). A header block 141 at the top of screen shot 134 indicates that the unit associated with status board 136 is “Cardiology ICU N Tower.”

Continuing from left to right in FIG. 2, screen shot 134 includes a notes column 142 which shows notes that caregivers have entered about various patients. Examples of some of the notes in screen shot 134 include, “Hard of hearing, Latex allergy;” “Contact precaution, droplet precaution;” “Open chest, Airborne plus, Family only, No . . . ;” “C diff, TB;” “Confused, Latex allergy, Can't speak, Can't hear;” and “Neutropenic, No outside . . . .” Thus, while the notes may include anything caregivers have entered about the patient, it can be seen from the illustrative examples that the notes generally relate to the corresponding patient's medical conditions, physical limitations, allergies, contagion risk, and visitor limitations.

The next column in FIG. 2 is a risks column 144 which has icons to indicate a corresponding patient's medical risks. Up to three icons can be shown in column 144 for each patient in the illustrative embodiment. More particularly, in the illustrative example, the three icons includes a falls risk icon 146 to indicate that the corresponding patient is a falls risk, a pulmonary risk icon 148 to indicate that the corresponding patient is at risk of developing pulmonary complications such as ventilated assisted pneumonia (VAP), and a skin risk icon 150 to indicate that the corresponding patient is at risk of developing pressure ulcers (aka bed sores or decubitus ulcers).

To the right of column 144 in screen shot 134 is an out-of-room column 152 that includes an out of room icon 154 if a corresponding patient has left their patient room, such as for therapy, x-rays, etc. or to be discharged from the healthcare facility. Column 152 also includes a bed exit alarm call icon 156 if the corresponding patient has gotten out of bed when the patient position monitoring (PPM)/bed exit system of the associated patient bed has been armed (e.g., turned on) to monitor for patient bed exit or movement toward bed exit.

The next column in screen shot 134 of status board 136 is a calls column 158 which shows all the active calls for the various patient rooms and also shows the wait time, in minutes, subsequent to the occurrence of the respective call. Such calls in column 158 are based on alerts or alarms from equipment in the room, such as the patient beds, or based on a patient pressing a nurse call button on the corresponding patient bed or a pillow speaker unit or based on a caregiver or other staff action in the patient room. For example, in row four 160 of screen shot 134, a caregiver has pulled a code blue lever on a room station (e.g., a GRS or a standard room station) in the corresponding patient room and a “+ Code Blue” message appears in column 158. This same message appears in header block 141 along with the room “1203N-A” corresponding to the room in which the code blue is occurring. The term “code blue” means that the corresponding patient has gone into respiratory or cardiac arrest and likely requires cardiopulmonary resuscitation (CPR).

In the illustrative example of FIG. 2, other calls appearing in column 158 include the following: “Bed Disconnected Call” to indicate that the patient bed in the corresponding room has become unplugged from power or from the nurse call system 12; “Too Few Rails Up” to indicate that one or more siderails of the patient bed have been lowered for a patient who is a falls risk, for example; “Bed Exit Off Alert” to indicate that the PPM/bed exit system of a patient bed in a room of a patient who is a falls risk has been disarmed (or turned off so as not to monitor the patient's position or bed exit); “Normal” to indicate that the patient has pressed a nurse call button to speak with or summon a caregiver; “Staff Call” to indicate that a staff member in a particular patient room is placing a call to another staff member using a room station, a badge or tag with communication capability, or the associated mobile phone 18; “Staff Emergency” to indicate that one staff member has placed an emergency call using a staff locating tag/badge, or using a room station to summon one or more other staff members, or using the associated mobile phone 18 to summon one or more other staff members; “Bed Exit Alarm Call” to indicate the corresponding patient has gotten out of bed when the patient PPM/bed exit system of the associated patient bed has been armed (e.g., turned on) to monitor for patient bed exit or movement toward bed exit; and “Bed Brakes Alert” to indicate that caster brakes of the corresponding patient bed have been unbraked or released.

Continuing from left to right in FIG. 2, an assigned staff column 162 shows the staff members who are assigned to each of the patient rooms in the unit. In the illustrative example, there are two staff members (e.g., caregivers) assigned to each patient room. The format for showing the assigned caregivers in column 162 is full first name followed by first letter of last name. To the right of the name designation in column 162 is a role designator, typically an acronym, for each staff member. In the illustrative example of FIG. 2, the role designators include “RN” for registered nurse and “CNA” for certified nursing assistant. To the right of the role designators in column 162 are the phone numbers or extensions for each staff member, which are the phone numbers of the associated mobile phones 18 in some embodiments.

The next column of screen shot 134 of status board 136 is a bed rails column 164 that shows a patient and bed siderails icon with color coding to indicate the status of the siderails of each patient bed in each of the corresponding patient rooms. The icon is a simplified view from above the patient such that four line segments around the patient icon portion are representative of the four bed siderails. The patient icon portion has a small circle indicative of the patient's head such that the two line segments adjacent the small circle of the patient icon portion represent the head end siderails of the corresponding patient bed and the other two line segments are the foot end siderails of the corresponding patient bed.

With regard to the color coding of the icons appearing in column 164 for siderail status, green indicates that the corresponding siderail is in a raised position inhibiting patient exit from the respective bed; yellow indicates that the corresponding siderail is lowered but does not result in an alert or alarm condition, such as if a caregiver is in the patient room and has assisted the patient in getting out of bed or the PPM/bed exit system is not armed such that patient position and bed exit is not being monitored, or if no patient is assigned to the corresponding bed; and red indicates that the corresponding siderail is lowered and results in an alarm condition which, in turn, results in a call being placed and appearing in calls column 158. The patient portion of the icons appearing in column 164 is also color coded such that green indicates that a patient is sensed to be in the corresponding patient bed and gray indicates that no patient is sensed to be in the corresponding patient bed.

To the right of column 164 in screen shot 134 is a bed status column 166 which includes three sub-portions including sub-portion 166a to indicate bed exit status for each patient bed in the corresponding unit, sub-portion 166b to indicate bed low status for each patient bed in the corresponding unit, and sub-portion 166c to indicate brake on status for each patient bed in the corresponding unit. In sub-portion 166a of column 166 a check mark means the PPM/bed exit system is armed; an X mark means that the PPM/bed exit system is not armed; an empty triangle means the PPM/bed exit system it not armed but should be for a falls risk patient, or that a patient is absent from the room or not assigned to the room; a dash indicates that no patient bed is currently transmitting bed status data from the corresponding room; and a filled in triangle means that the PPM/bed exit system is armed and is alarming because the corresponding patient has exited the bed or has moved toward exiting the bed by a threshold amount (e.g., depending the mode of the PPM/bed exit system).

With regard to sub-portion 166b of column 166, a check mark means that an upper frame of the corresponding bed is in its low position, an X mark means the upper frame of the corresponding bed is not in its low position, and a dash indicates that no patient bed is currently transmitting bed status data from the corresponding room. With regard to sub-portion 166c of column 166, a check mark means that casters brakes of the corresponding bed are braked (e.g., locked or “on”), an X mark (not shown in FIG. 2) means that the caster brakes of the corresponding bed are unbraked (e.g., unlocked or “off”), an empty triangle means that a bed brakes alert is occurring such as for a corresponding falls risk patient, and a dash indicates that no patient bed is currently transmitting bed status data from the corresponding room.

To the right of bed status column 166 is a head of bed (HOB) column 168 that contains an angle at which a head section of the corresponding bed is raised relative to the upper frame of the corresponding bed or relative to horizontal depending upon the type of angle sensor used (e.g., potentiometer or accelerometer). Some patient beds permit a HOB alarm to be turned on which results in an alarm being sent if the HOB angle drops below a threshold angle, such as 30 or 45 degrees, for example. In such patient beds, a HOB alarm message appears in calls column 158 for the corresponding bed. To the right of HOB column 168, a scroll bar 170 and is movable vertically to reveal additional patient rooms and patients in the unit along with corresponding information of the type just discussed with regard to screen shot 134 of FIG. 2.

Still referring to FIG. 2, screen shot 134 of status board 136 includes a first window 172 that lists the names, phone number, and location of a charge nurse and a unit clerk for the associated unit. Beneath first window 172 is a second window 174 that lists the names, phone numbers, and locations of the located staff of the unit. The locations shown in windows 172, 174 are based on information transmitted to nurse call system 12 from locating system 34. The names shown in windows 172, 174 are in the same format as the names shown in assigned staff column 162. That is, full first name followed by first letter of last name. In some embodiments, the phone numbers shown in windows 172, 174 are the phone numbers of mobile phones 18 that are carried by caregivers and other staff.

Referring now to FIG. 3, an example of a bed board screen shot 176 which appears on the display of the mobile phone 18 is shown. The information shown in screen shot 176 is based on selection of a My Patients button 178 near the top of screen shot 176. Thus, the information shown in screen shot 176 is associated with the patients that have been assigned to the particular caregiver in possession of the corresponding mobile phone 18. As shown on screen shot 176, windows 180a, 180b, 180c, 180d are provided for four of the caregiver's six assigned patients. To see the information for the other two patients assigned to the caregiver, the caregiver simply swipes upwardly or downwardly on the display of mobile phone 18, as appropriate. If a Unit button 182 is selected by the caregiver in lieu of My Patients button 178 then additional windows, similar to windows 180a, 180b, 180c, 180d, are viewable on the display of mobile phone 18 for the additional patients in the unit, and the caregiver swipes upwardly or downwardly on the display of mobile phone 18, as appropriate, to see the information for the other patients in the unit.

Beneath the My Patients button 178 a text string 184 is provided on screen 176 indicating that the caregiver's unit is “Duke: Tower One.” A drop down menu arrow 186 is situated adjacent to text string 184 and is selectable to bring up a drop down menu of other units of the caregiver's healthcare facility. Selection of a different unit results in the caregiver's assigned patient list and unit patient list to be updated, as appropriate (e.g., the caregiver may not have any assigned patients in other units). Beneath the Units button 182 is a text string 188 which states “Sort by Time” to indicate that the list of patients is sorted by the time since an alarm occurred or a call was other detected or placed. However, as shown in window 180a, a code blue call takes precedence over all other calls regardless of time since occurrence. For other calls, they are listed such that the oldest call is first, the second oldest call is second, and so on. In screen shot 176, window 180b shows a wait time of 5 minutes, window 180c shows a wait time of 4 minutes, and window 180d shows a wait time of three minutes. The wait times are shown in the upper right corner regions of windows 180a, 180b, 180c, 180d.

Next to text string 188 is a drop down menu arrow 190 which is selectable to sort the My Patients list and the Units list in some other manner, such as alphabetically by patient name or in room number order. Selection of a different sort methodology results in the My Patients list and Units list being updated accordingly. Each of windows 180a, 180b, 180c, 180d includes each patient's full name, the room number for the respective patient, a text description of any alarms or alerts (these terms are used interchangeably herein), and any icons associated with the alarms or alerts. The icons match the icons appearing on the bed status board 136 for the particular alert or call. In window 180d, a locating icon is provided to indicate that a medical doctor (MD) is located in the corresponding patient room and the associated text indicates there is an additional person (i.e., “+1”) in the room as well.

An indicator box is provided beneath the foregoing information to indicate with the call or alert is new, waiting, or updated. Each window 180a, 180b, 180c, 180d includes a field 192 at the bottom region thereof with information regarding, from left to right, the patient's weight, whether the patient is sensed as being in bed, any reminders (e.g., rounding reminders or turn reminders) and the amount of time before the reminded action is due, and whether any bed alarms for the corresponding patient are occurring. Risk icons for any patient risks of the corresponding patient are shown above the right side of fields 192. The risk icons match those appearing in column 144 of status board 136 in some embodiments. At the bottom screen 176 of FIG. 3, a menu 194 of navigation icons are provided. Menu 194 includes a bed board icon 196 which is shown to be the currently selected navigation icon, a calls icon 198 which is selected to navigate to calls information, a to do icon 200 which is selected to navigate to the associated caregiver's to do list, a reports icon 202 to navigate to various reports and staff metrics, and a location icon 204 to navigate to location information for the healthcare facility.

Based on the foregoing, it should be appreciated that the present disclosure contemplates that all information appearing on status board 136 is viewable on the mobile devices 18 assigned to the respective caregivers of the corresponding unit of the healthcare facility. For example, in some embodiments, the caregiver is able to tap within a selected window 180a, 180b, 180c, 180d to bring up more information from status board 136 regarding the corresponding patient for viewing on the display of the associated mobile phone 18. The present disclosure also contemplates that the caregivers can provide user inputs on their mobile phones 18 to add and remove notes from column 142; to designate and de-designate patient risks from column 144, thereby causing icons 146, 148, 150, as the case may be, to appear in column 144 for selected patients or to disappear from column 144 for selected patients; and to place staff calls and staff emergency calls which appear in column 158; and to indicate that calls appearing in column 158 have been taken care of and can be cleared from column 158.

Referring now to FIG. 4, a reminders screen shot of a graphical room station (GRS) 208 of the nurse call system 12 of FIG. 1 is show with a list of reminders or tasks, in the form of buttons, that an assigned caregiver is to perform for a patient in the room having the GRS 208. In the illustrative FIG. 4 example, screen shot 206 includes a 60-minute recheck reminder 210, a 30-minute recheck reminder 212, a turn due reminder 214, and a round due reminder 216. A timer 218 is provided at the upper right corner of reach reminder 210, 212, 214, 216 indicating the amount of time, in hours: minutes format, before the particular reminder or task is due. Thus, reminder 210 is due in 60 minutes, reminder 212 is due in 30 minutes, reminder 214 is due in one 1 hour and 60 minutes (aka 2 hours), and reminder 216 is due in 60 minutes.

After a caregiver completes the task associated with a particular reminder 210, 212, 214, 216, the caregiver selects the button or the particular reminder 210, 212, 214, 216 by touching or tapping the button on the display of the GRS 208 which clears the reminder from system 10 or provides a subsequent screen with an input for the caregiver to select to clear the reminder. Above the reminders 210, 212, 214, 216 on screen shot 206 are a bed button 220 which is selected to view reminders associated with the corresponding patient's bed, a complete all button 222 which is selected to clear all of the reminders 210, 212, 214, 216 as being completed by the caregiver, a hold specific button 224 which is selected to indicate that a particular one of reminders 210, 212, 214, 216 is to be paused from being completed, and a hold all button 226 which is selected to indicate that all of reminders 210, 212, 214, 216 are to be paused. When some or all of reminders 210, 212, 214, 216 are paused, the associated timer 218 ceases from continuing to count down during the pause period. If hold specific button 224 is selected, then the specific reminder 210, 212, 214, 216, as the case may be, is subsequently selected to indicate which specific reminder is to be paused.

At the bottom of screen shot 206, from left to right, are a menu button 228 which is selected to navigate to a main menu of the GRS 208, an emergency button 230 which is selected by a caregiver to summon other caregivers to come to the associated room due to an emergency (e.g., a combative or uncooperative patient), an assist button 232 which is selected by a caregiver to place a call to another staff member, and a cancel button 234 which is selected to cancel a call or alert that originated in the patient room in which the GRS 208 is fixed in place. The present disclosure contemplates that some or all of the features and functions concerning reminders 210, 212, 214, 216, 216 and buttons 220, 222, 224, 226, 228, 230, 232, 234 of GRS 208 are also able to be performed using mobile phones 18 of system 10.

Referring now to FIG. 5, an example of a to do screen shot 236 of the mobile phones 18 of FIG. 1 is provided. Portions of screen shot 236 of FIG. 5 that are similar to like portions of screen shot 176 of FIG. 3 are denoted with like reference numbers and the descriptions are not repeated. As shown on screen shot 236, a list of reminders, in the form of windows 238a, 238b, 238c, 238d, 238e, are shown for the patients assigned to the caregiver associated with the mobile phone 18. In the example of FIG. 5, window 238a shows a pain reminder indicating that pain medication delivery is overdue by 6 minutes, 45 seconds (indicated by “−06:45); window 238b shows a turn reminder indicating that a corresponding patient's turn in bed is due in 3 minutes, 25 seconds (indicated by “03:25”); window 238c shows a temperature reminder indicating that a corresponding patient's temperature is to be taken in 4 minutes, 25 seconds (indicated by “04:25”); window 238d shows a medication reminder that is due in 7 minutes (indicated by “07:00”); and window 238e shows that housekeeping has been summoned to a corresponding patient room less than 1 minute ago.

Windows 238b, 238c, 238d have text above the reminder names to indicate that the corresponding task is a recurring task. In the illustrative example, the reminders of windows 238b, 238c, 238d each recur or repeat every 60 minutes. Window 238e includes a slider 240 that is selected to toggle between on and off positions to indicate whether housekeeping is needed in the corresponding patient room, when in the on position, or not needed in the corresponding patient room, when in the off position. As is apparent in the preceding paragraph, the time left before a particular task associated with a reminder is due is provided in minutes: seconds format, with a negative sign indicating that the particular task is overdue.

Each of windows 238a, 238b, 238c, 238d includes a right arrow icon 242 which is selectable to view more information (e.g., room number and patient name) regarding the particular reminder and to view user inputs, such as icons or buttons, for managing the respective reminders (e.g., clear the reminders, reset the reminders, and pause the reminders). In response to use of the user inputs of the mobile phones 18 by caregivers to clear, reset, or pause the reminders, messages are transmitted back through mobile app gateway 16 and/or CSA 14 to nurse call system 12 which updates status board 136 and GRS 208 accordingly. At the bottom of screen shot 236, to do icon 200 is highlighted to indicate that the to do information of the corresponding caregiver is to be provided on the display of mobile phone 18 (note that the bed board icon 196 should not be highlighted in FIG. 5).

Referring now to FIG. 6, an example is shown of a caregiver metrics graph 244 that is viewable on a screen of the mobile phone 18 of the respective caregiver in response to selection of reports button 202 of menu 194. Graph 244 is a bar graph showing the time in hours on the y-axis of the graph 244 that the caregiver spent with each of the caregiver's assigned patients during a particular shift. The bars of the bar graph 244 are shown generically as corresponding to Patient 1, Room A; Patient 2, Room B; Patient 3, Room C; and Patient 4, Room D along the x-axis. In an actual implementation, the names of the patients are shown in graph 244 (e.g., full patient name or HIPAA compliant version of patient name) along with the corresponding room number.

In graph 244, a first horizontal dotted line 246 shows the target amount of time that caregivers should endeavor to spend with each of their patients during a shift and a second horizontal dotted line 248 shows the average amount of time that caregivers in the unit spent with their assigned patient's during the shift. Also in graph 244, a dashed horizontal line 250 shows the average amount of time that the respective caregiver spent with the caregiver's assigned patients during the caregiver's shift. Graph 244 also includes, in the upper right corner region, a share button 252 for selection by the caregiver of the mobile phone 18 on which graph 244 is displayed to send a copy of the graph to other staff members.

Referring now to FIG. 7, an example of a share graph screen shot 254 is shown. Screen shot 254 appears on the touchscreen display of the respective caregiver's mobile phone 18 in response to selection of share button 252 of graph 244. As shown in FIG. 7, a duplicate graph 244′ is displayed and contains the same information as graph 244 except that graph 244′ does not include display button 252. The present disclosure contemplates that, in response to selection of share button 252, the caregiver's mobile phone 18 launches another application for sending secure text messages to other caregivers in the healthcare facility. An example of such an application is the VOALTE® communication application available from Hill-Rom Company, Inc. of Batesville, IN, U.S.A. At the top of screen shot 254 is a back button 256 the selection of which returns the caregiver back to the mobile application for linking the mobile phone 18 with nurse call system 12.

Beneath back button 256 of screen shot 254 is a text message recipient field 258 in which recipients of the text are listed. In the illustrative example, field 258 includes the text “To: Mary Strong Dale Andrews” to indicate that two recipients are to receive the text message having graph 244′. Just above graph 244′ of screen shot 254 is a text message field 260, which in the illustrative example includes two lines of text. The first line of text is, “Look how needy this patient was!” and the second line of text is “Can I get a witness for meds?” A keyboard 262 is provided on the display of the caregiver's mobile phone 18 for use to type the text message(s) in field 260. Screen shot 254 also has a send arrow 264 to the right of field 260 for selection to send the text message(s) and graph 244′ to the recipients listed in field 258.

Based on the foregoing, it will be appreciated that the present disclosure contemplates that mobile phones 18 of system 10 are usable for at least the following functionality, some of which have been discussed hereinabove: View patient, room, & bed data; Answer Nurse Calls; submit Action Requests (ARBs); handle Reminders (View, Pause, Reset, Complete); Staff Locator (from RTLS 34); Asset Locator (from RTLS 34); Interapp Linking such as to the VOALTE® communication application and EMR system linking; Updating Risks; Patient Safety Alerts (including toggling); and Shift metrics & reporting.
