The present disclosure relates generally to healthcare communication systems such as patient-nurse communication systems, and more particularly to implementing safety protocols that include alerts of the healthcare communication system being set based on conditions of a patient.
Healthcare communication systems typically include information and communication technologies to support health services conducted in a healthcare facility setting. For example, some healthcare communication systems include patient-nurse communication systems or “nurse call” systems that facilitate communication among members of a nursing staff and other persons dispersed throughout the healthcare facility. The nurse call systems generally provide information about the present status or condition of patients in the healthcare facility, and may additionally provide information regarding status information pertaining to patient supports (e.g., hospital beds, chairs, lifts, stretchers, etc.) throughout the healthcare facility. Examples of such prior art nurse call systems are Hill-Rom's COMposer™ communication system and Hill-Rom's COMLinx™ communication system.
Typically, a member of the nursing staff sets which alerts the nurse call system will provide based on a safety protocol, such as a fall risk safety protocol assigned to a patient that has been identified as a fall risk, and maintains compliance with the safety protocol. Under the fall risk safety protocol, it may not be desirable for the fall risk patient to get out of bed unless a caregiver is present in the room to assist the fall risk patient. Accordingly, an alert may be set to trigger an alert, or notification, at the nurse call system when the fall risk patient exits a hospital bed, for example. Additionally, sensory indicators (e.g., visual, audible, etc.) are often associated with the nurse call systems to notify the hospital staff of the present state of the alerts, such as whether they are alarmed, or triggered. For example, a sensory indicator may be alarmed to indicate that an alert was violated, such as when the falls risk patient has exited the hospital bed.

The detailed description refers to the following figures in which:
Aspects of the present invention are described with reference to certain illustrative embodiments shown in the accompanying drawings and described herein.
In general, a healthcare communication system includes one or more staff or nursing computers or computing devices, which may be referred to as stations or consoles. The stations or consoles, in cooperation with various computers, networks, and supporting equipment and services, enable nurses and other staff to receive, view, manage, and route, output, or respond to electrical and wireless signals from a variety of communication, call, monitoring, detecting, and/or signaling devices. Some communication, call, monitoring, detecting, and/or signaling devices are activated by patients, staff, or visitors. Others are activated by the occurrence of an event or alarm condition detected by signal receivers, patient monitoring equipment, or patient supports (e.g., hospital beds) located throughout a healthcare facility, such as from sensors integrated into hospital beds. For example, when the healthcare communication system receives a signal from a communication, call, monitoring, detecting, and/or signaling device, one or more indicator assemblies may be activated to alert hospital staff (e.g., nurses, caregivers, etc.) of the condition or event being signaled by the communication, call, monitoring, detecting, and/or signaling device. Accordingly, the hospital staff may respond based on the alert condition (i.e., an alarmed alert) or event signaled by the communication, call, monitoring, detecting, and/or signaling device. Additionally, the healthcare communication system is configured to log patient data, which the hospital staff may rely upon when treating patients at the healthcare facility.
One such embodiment of a healthcare communication system 100 to manage communications throughout the healthcare facility is diagrammatically illustrated in
As such, an analysis can be performed at the hospital information system 102 on the patient data and the care asset data. For example, as will be described in further detail below, the care asset data may be compared against patient outcomes that can be used to determine whether a correlation exists between a particular negative patient outcome and one or more care assets that are either presently in use by a patient or available to be assigned to a patient. Accordingly, a present safety protocol can be adjusted based on whether the correlation exists. In other words, the safety protocol implemented for a particular patient can be modified to reduce or altogether eliminate a health risk identified for that patient based on the identified negative patient outcome resulting from the one or more care assets. Further, the modifications to the safety protocol may trigger a care asset 120 affected by the modifications to take measures to ensure the modification is being adhered to, such as by ensuring other care assets 120 are present in accordance with the adjusted safety protocol and/or activating additional/or alternative alerts in accordance with the adjusted safety protocol. Still further, a particular safety protocol may be activated or modified based on a detected use of a particular care asset 120, if that care asset 120 part of the active safety protocol, the usage of which therefore indicates that the patient's status has changed.
The safety protocol includes one or more protocols, such as care protocols, therapy protocols, preventative protocols, etc., that are each associated with a patient care action or care asset 120. Further, each of the protocols of the safety protocol may also include one or more sub-protocols. For example, a patient may be identified as a falls risk and a pressure ulcer risk. Accordingly, the safety protocol may include a falls risk safety protocol and a skin safety protocol for that patient. Further, because the patient is a pressure ulcer risk, which is a particular skin safety concern, a pressure ulcer prevention sub-protocol may be implemented. As such, the care assets 120 associated with the more specific pressure ulcer prevention sub-protocol may be assigned to the patient, rather than the care assets 120 associated with the more broad skin safety protocol, which may include care assets 120 that are not necessary or that may not directly address the pressure ulcer risk. For example, a particular patient support surface/mattress may be sufficient for a skin safety protocol, while a different, more specialized patient support surface/mattress is indicated for a patient with a pressure ulcer risk. Further, settings of the care assets 120 relevant to the pressure ulcer prevention sub-protocol may be changed (e.g., frame controls set to prevent a head-of-bed angle greater than one of 30 or 45 degrees, as defined by the pressure ulcer prevention sub-protocol) and/or alerts relevant to the pressure ulcer prevention sub-protocol may be changed (e.g., a chair pressure pad and chair sensing system set to alert if a patient is on the chair and the pressure reducing chair pad is not in use).
To perform the analysis, as well as to facilitate the transfer of data and other network communications across the hospital information system 102, the hospital information system 102 includes a number of computing devices 104. Each of the computing devices 104 may be embodied as any type of computation or computer device capable of performing the functions described herein, including, without limitation, a server (e.g., stand-alone, rack-mounted, blade, etc.), a network appliance (e.g., physical or virtual), a high-performance computing device, a web appliance, a distributed computing system, a computer, a processor-based system, a multiprocessor system, a smartphone, a tablet computer, a laptop computer, a notebook computer, and/or a mobile computing device. The illustrative computing device 104 of
The processor 106 may be embodied as any type of processor capable of performing the functions described herein. For example, the processor 106 may be embodied as a single or multi-core processor(s), digital signal processor, microcontroller, or other processor or processing/controlling circuit. The memory 110 may be embodied as any type of volatile or non-volatile memory or data storage capable of performing the functions described herein. In operation, the memory 110 may store various data and software used during operation of the computing device 104 such as operating systems, applications, programs, libraries, and drivers. The memory 110 is communicatively coupled to the processor 106 via the I/O subsystem 108, which may be embodied as circuitry and/or components to facilitate input/output operations with the processor 106, the memory 110, and other components of the computing device 104. For example, the I/O subsystem 108 may be embodied as, or otherwise include, memory controller hubs, input/output control hubs, firmware devices, communication links (i.e., point-to-point links, bus links, wires, cables, light guides, printed circuit board traces, etc.) and/or other components and subsystems to facilitate the input/output operations.
The data storage device 112 may be embodied as any type of device or devices configured for short-term or long-term storage of data such as, for example, memory devices and circuits, memory cards, hard disk drives, solid-state drives, or other data storage devices. In use, as described below, the data storage device 112 and/or the memory 110 may store security monitoring policies, configuration policies, or other, similar data. The communication circuitry 114 may be embodied as any communication circuit, device, or collection thereof, capable of enabling communications between the computing devices 104 and/or between one of the computing devices 104 and the care assets 120. The communication circuitry 114 may be configured to use any one or more communication technology (e.g., wired or wireless communications) and associated protocols (e.g., Ethernet, Bluetooth®, Wi-Fi®, WiMAX, etc.) to effect such communication.
The computing devices 104 of the hospital information system 102 may be configured into separate subsystems for managing data and coordinating communications throughout the hospital information system 102. For example, in an illustrative hospital information system 200 shown in
The nurse call system 210 is configured to operate and manage many of the primary nurse call functions of the hospital information system 102. For example, the nurse call system 210 may be configured to receive and manage messages from various connected devices (e.g., the care assets 120), coordinate assignment of patients to hospital supports, and/or to synchronize connected devices within the healthcare communication system 100 that are in network communication with the nurse call system 210. Additionally or alternatively, the nurse call system 210 may be configured to answer, control placement of, and cancel calls, as well as generate alarms, acknowledge and cancel alarms, and/or manage location information for staff and the care assets 120. Accordingly, the illustrative nurse call system 210 includes a care asset state database 214 in which to store care asset state information. The care asset state information may include any type of data indicative of a present state of a care asset and/or an alert associated with, or triggered by, a care asset (e.g., whether an alert is in an alarmed state).
It should be appreciated that the nurse call system 210 is configured to interface with the various care assets 120 at the structure 118, such that the alerts, described in further detail below, may be triggered by the care assets 120 and an indication of such triggered alerts may then be transmitted to the nurse call system 210 for reconciliation. As such, a communication interface (not shown) of the network 116 for facilitating network communications across the network 116 may be present within the structure 118 (e.g., an Ethernet port on a wall in a hospital room of the structure 118, a wireless access point accessible to a ward of the structure 118, etc.). Additionally, the care assets 120 may include a communication interface (see the communication circuitry 300 of
To support the interactions between the staff and the nurse call system 210 (i.e., to indicate the state of the alerts for a particular patient and/or care asset 120), the illustrative nurse call system 210 includes a user interface (UI) 212. In some embodiments, the user interface 212 may include a display (not shown) that is operable to generate or display a graphical user interface (GUI) to enable the staff to interface with the nurse call system 210. Additionally or alternatively, in some embodiments, the user interface may include visual indicators (e.g., light emitting diodes (LEDs)) that represent different states of the care assets 120 and/or the alerts representative thereof, and/or audible indications (e.g., via a speaker) that indicate the different states of the care assets 120 via tone and/or spoken language (e.g., via a voice generator). Further, in some embodiments, the nurse call system 210 may be additionally configured to activate/deactivate staff, manage staff-patient assignments, assign and manage roles and responsibilities to staff and devices, as well as manage patient information and patient discharges/transfers.
In use, the EMR system 220 aggregates and stores the medical and clinical data of the healthcare communication system 100 of
The care asset management system 230 is configured to manage care assets of the healthcare communication system 100. To do so, in some embodiments, the care asset management system 230 may store information relative to the care assets 120 of the healthcare communication system 100 in a care asset information database 232. The care asset information stored at the care asset information database 232 may include any type of data that is indicative of a state of a care asset 120, such as a component usage history, a maintenance history, an assignment history, an illness exposure history, etc. Additionally, the illustrative care asset management system 230 includes a care environment database 234 in which to store care environment information. The care environment information may include any type of information indicative of the environment of a care asset 120 assigned to a patient, such as a location, a temperature level, a lighting condition, a pressure reading, a position setting, an alert setting, etc.
The safety protocol management system 240 is configured to manage the safety protocols of the healthcare communication system 100. As described previously, each of the safety protocols includes a number of various protocols (e.g., care protocols, therapy protocols, preventative protocols, etc.) and sub-protocols that are typically based on the present conditions of a patient and/or expected conditions of the patient, as well as the care assets 120 assigned to the patient. Accordingly, the illustrative safety protocol management system 240 includes a safety protocol database 244 for storing the safety protocols.
In some embodiments, the safety protocol may be based on a patient scoring system to determine a risk score determined from a set of established risk factors or arise from a doctor's order, for example. Illustratively, the safety protocol includes a set of defined procedures (i.e., instructions) that, when executed, prompt members of the hospital staff to ensure certain precautions are taken. Additionally, the safety protocol includes a set of alerts to be set relative to the presently implemented safety protocol. For example, a falls risk protocol may be implemented for a patient identified as a falls risk. In such an embodiment, the falls risk protocol may activate an alert that will alarm (i.e., provide a notification) when a falls risk patient exits a patient support apparatus 122, such as a hospital bed, a chair, a toilet, etc. In other words, an exit alarm may be activated at one or more of the patient support apparatuses 122 assigned to the patient, or in the hospital room in which the patient is assigned, based on the implemented safety protocol.
Further, in some embodiments, elements of the care environment (e.g., lights, sensors, etc.) may be adjusted based on the safety protocol. Accordingly, the safety protocol may include one or more care environment settings. The care environment settings may include a minimum illumination (e.g., lumens) level, a light (e.g., mounted on the floor, wall, ceiling, hospital bed, etc.) setting, a sensor (e.g., motion detection) setting, and/or the like. Additionally, in some embodiments, a sensory (e.g., audible and/or visible) designation may be provided based on the safety protocol, such as a message on a display component (e.g., on electronic patient signage) placed in a location that is visible by the hospital staff and/or one or more other care assets 126 that can be assigned to the patient based on the safety protocol (e.g., red socks to indicate the patient is a falls risk). Accordingly, in such embodiments wherein the visible designation requires one or more of the other care assets 126, the other care asset 126 may be automatically ordered when the safety protocol is designated for that patient, such as by an instruction from the safety protocol management system 240 (e.g., via the safety protocol module 242) to the care asset management system 230.
The illustrative safety protocol management system 240 additionally includes a safety protocol module 242 that may be executed on one or more of the computing devices 104. The safety protocol module 242 may be embodied as, or otherwise include, any type of hardware, software, and/or firmware capable of performing the functions described herein. As will be described in further detail below, the safety protocol module 242 is configured to manage the safety protocols. To do so, the safety protocol module may be configured to retrieve the care asset state information of the care asset state database 214, the patient information of the patient information database 222, the care asset information of the care asset information database 232, and/or the care environment information of the care environment database 234.
Based on the retrieved data, the safety protocol module 242 can perform an analysis to determine whether a condition exists such that a care asset 120 or a current condition of a care asset 120 presents a health risk (e.g., a potentially adverse event) to a particular patient. For example, the safety protocol module 242 may analyze the retrieved data (e.g., care asset state information, patient information, care asset information, patient outcomes, etc.) and determine that a care asset 120 is a potential carrier of a health risk (e.g., a bacteria known to cause an infection) upon detecting that the care asset 120 came into direct or indirect contact with one or more patients whose outcomes resulted in development of the health risk (e.g., the infection). Similarly, the safety protocol module 242 can perform an analysis to determine whether a condition exists at a rate higher than a predicted rate, and identify a root cause (e.g., a care asset 120, a care activity, etc.). For example, a particular surface of a patient support 122 may have been used to support multiple patients, of which a higher than predicted rate experienced a particular health risk (e.g., a sacral pressure ulcer).
As a result of identifying a health risk, in use, the safety protocol module 242 can adjust the safety protocol (i.e., additional and/or alternative care assets 120 and/or alerts) based on the identified care asset 120 that has been determined to pose the health risk. For example, in the embodiment wherein use of the particular surface of a patient support 122 results in higher than the predicted rate as described above, the safety protocol module 242 may enact a particular protocol related to defective patient support 122 surface. In such embodiments, the safety protocol module 242 may reduce a maximum head-of-bed angle to 10%, reflecting the surface's inability to support the pelvic section, increase air flow to trade increased noise and decreased efficiency for optimized pressure management, and/or perform automated or manual local and/or remote communication the surface's compromised status, such as by warning a caregiver that the surface is not appropriate for high-risk patients or scheduling for maintenance, for example. It should be appreciated that any additional and/or alternative therapy may result based on the analysis. In other words, the safety protocol adjustment may be made based on a determination that a particular therapy is projected to result in an outcome that is less likely to introduce a health risk than another therapy.
In some embodiments, the safety protocol is adjusted by the detection of an action by a member of the hospital staff, such as the use of a particular care asset 120 and/or the setting of an alert. For example, in an embodiment wherein a patient is not identified as a falls risk patient, the activation of an exit detection system on a patient support apparatus 122 may cause the safety protocol module 242 to modify the patient's status to reflect that the patient has transitioned to become a falls risk. In another example, during compliance with the safety protocol, use of (e.g., opening, prepping, administering, etc.) a care asset 120 associated with the safety protocol may determine whether one or more additional care assets 120 associated with the safety protocol are assigned and/or whether one or more care activities associated with the safety protocol are scheduled, or being performed. In such embodiments, one or more care assets 120 relevant to the safety protocol may be sensed to determine whether the one or more care assets 120 relevant to the sub-protocol are in a desired state (e.g., assigned to the patient, in proximity to the patient, scheduled for delivery to the patient, at a desired position, etc.). For example, in an embodiment wherein a caregiver initiates a continuous lateral rotation therapy (CLRT) in compliance with a sub-protocol of the ventilator associated pneumonia (VAP) prevention protocol, a head-of-bed alarm may be set to sound if the head-of-bed angle is less than 30°, a sensory receivable message (e.g., “High infection risk—gloves and mask required!”) may be initiated, and a respiratory therapy device automatically dispatched from a central supply to the patient's room, such as via the care asset management system 230.
Referring again to
As noted previously, the care assets 120 include patient support apparatuses 122, as well as other care assets 126. The patient support apparatuses 122 may be embodied as, but are not limited to, a hospital bed, a chair, a toilet, a lift, a sling, and/or a stretcher. The other care assets 126 may include, but are not limited to, an article of clothing (e.g., gloves, socks, masks, gowns, etc.), a pad for a patient support apparatus 122 (e.g., a mattress pad for a hospital bed, a cushion for a chair, etc.), a bedding item for a patient support apparatus 122 (e.g., a sheet, a blanket, etc.), a catheter, a central line kit, and/or a ventilator. Still other care assets 126 may include monitors such as blood pressure monitors, EKG monitors, EEG monitors, SpO2 monitors, heart rate monitors, respiration monitors, scales, thermometers and/or telemetry systems, etc. Still other care assets 126 may include therapy delivery systems including infusion systems, sequential compression devices, and/or exercise equipment, etc. While the illustrative healthcare communication system 100 includes a single patient support apparatus 122 contained within the structure 118, it should be appreciated that any number of patient support apparatuses 122 may be located in a healthcare communication system 100 of a healthcare facility. As such, any number of patient support apparatuses 122 may be communicatively coupled to the hospital information system 102 along with a combination of care assets 126.
As shown in
Further, due to the differences associated with each of the patient support types (e.g., a hospital bed versus a chair), each of the patient support apparatuses 122 may include fewer, additional, or alternative electronic components to the illustrative patient support apparatus 122 of
In another example, a hospital bed embodiment, a chair embodiment, or a toilet embodiment may have load cell sensors to detect a weight of a patient; however, the chair embodiment and/or the toilet embodiment likely do not have brakes, siderails, and/or adjustable height positions like that of the hospital bed embodiment. As such, the chair embodiment and the toilet embodiment would likely not include sensors and/or actuators typically associated with such features. Some of those similar components are shown in
The communication circuitry 300 is capable of establishing connections and facilitating communications to and from the patient support apparatus 122. The control system 124 is further configured to provide, or relay, status indications to a remote location, such as the nurse call system 210 of
The controller 302 of the control system 124 (i.e., an electronic control unit (ECU)) is connected to various sensors capable of being monitored and interpreted by the controller 302, and various actuators capable of being controlled by the controller 302. The controller 302 is configured to receive data (i.e., electrical signals) from the various sensors and components of the patient support apparatus 122, and control the operation of the components of the patient support apparatus 122 relative to the received data, as is known in the art. To do so, the controller 302 includes a number of electronic components commonly associated with controllers utilized in the control of electromechanical systems. For example, the controller 302 may include, amongst other components customarily included in such devices, a microprocessor 304 and a memory device 306. The memory device 306 may be, for example, a programmable read-only memory device (“PROM”) including erasable PROM's (EPROM's or EEPROM's). In use, the memory device 306 is capable of storing, amongst other things, instructions in the form of, for example, a software routine (or routines) which, when executed by the microprocessor 304, allow the controller 302 to control operation of the features of the patient support apparatus 122.
The patient support apparatus 122 may include various settings for adjusting certain components of the patient support apparatus 122. For example, in some embodiments, such as in a hospital bed embodiment, the patient support apparatus 122 may include an actuator interface 308 and/or a pump interface 310, which the controller 302 may use to adjust certain components of the patient support apparatus 122. The patient support apparatus 122 may include a number of actuators (not shown) capable of being controlled by the control system 124 to control various actuator-based components (e.g., motors, valves, power control units, etc.) via the actuator interface 308. For example, a designated angle of a headrest portion of the patient support may be adjusted relative to a deck of the patient support via the actuator interface 308. Similarly, the patient support apparatus 122 may include a number of pumps (not shown) capable of being controlled by the control system 124 to control various pump-based components (e.g., fluid-housing mattress pads, hydraulics, etc.). For example, a designated pressure level of a component of the patient support apparatus 122 (e.g., a bladder of a mattress) may be controlled by the control system 124 via the pump interface 310. It should be appreciated that additional and/or alternative component interfaces may be present in other patient support apparatuses 122.
The sensors 312 may include various position sensors 314, actuator sensors 316, pressure sensors 318, and/or brake sensors 320, depending on the type of patient support apparatus 122 and the functionality supported by the patient support apparatus 122. The position sensors 314 may be configured to sense a position of a particular component of the patient support apparatus 122, such as a height of a deck of the patient support apparatus 122, a position of a of the patient support apparatus 122 (e.g., raised or lowered position), and/or a position of an upper frame of the patient support apparatus 122 (e.g., in a raised or lowered position relative to a base frame of the patient support apparatus 122).
The actuator sensors 316 may be configured to sense a state (e.g., open/closed, on/off, etc.) corresponding to each actuator component of the patient support. The pressure sensors 318 may be configured to sense a pressure (e.g., a fluid pressure) of a pump-based component of the patient support apparatus 122. The brake sensors 320 may be configured to sense whether brakes (e.g., casters) of the hospital bed embodiment are braked or released. It should be appreciated that the sensors 312 may include additional and/or alternative sensors, such as, but not limited to, motion sensors, temperature sensors, level sensors, other position sensors, etc.
Additionally, in some embodiments, the patient support apparatus 122 may include a user interface (UI) 322 for setting various alerts that are capable of alarming, such as through the nurse call system 210, based on detected events that correspond to the sensor data. The UI 322 may include a display, such as a touchscreen display capable of generating input data in response to being touched by the user. Accordingly, in some embodiments, the control system 124 may additionally include additional circuitry to convert between analog and digital signals, such as an analog-to-digital (A/D) converter (not shown) or the like. The UI 322 may include various input and output devices capable of receiving input from a user (e.g., a patient, hospital staff, caregiver, etc.) and/or providing output to the user related to various sensor and/or configuration data of the patient support apparatus 122.
Additionally or alternatively, in some embodiments, the UI 322 may include a light configuration and/or a speaker to provide status indications of the patient support to the patient and/or the hospital staff. Accordingly, in some embodiments, the UI 322 may include a keypad (e.g., a keyboard, a touchpad, etc.) for receiving user touch-based inputs and/or a microphone for receiving audible-based inputs. In some embodiments, one or more of the input and/or output devices may be mounted on a siderail of the hospital bed embodiment, connected to a control pendant of the hospital bed embodiment, etc. It should be appreciated that, in some embodiments, the UI 322 may additionally or alternatively include a communication port, or wireless access control panel, that may be accessed via a connected device (e.g., via universal serial bus (USB)) or an application running on a remote computing device in network communication (e.g., Bluetooth®) with the patient support apparatus 122.

The process 400 then proceeds to step 410, wherein a safety protocol is determined, such as by the safety protocol module 242 the safety protocol management system 240 of
As described previously, various sub-protocols of the safety protocol may be triggered by the care assets 120, such as by use and/or proximity to a patient or of a care asset 120 assigned to the patient. For example, if the patient is assigned a central line kit via the care asset management system 230, a central line infection prevention protocol may be activated upon detection of the central line kit being in proximity to the patient. Accordingly, other care assets 120 may be sensed or otherwise confirmed to be assigned, such as via the care asset management system 230, as directed by the set of defined procedures (i.e., instructions) associated with the safety protocol that, when executed, prompt staff members of the hospital to ensure certain precautions are taken. Further, additional or alternative alerts may be set to active, based on the activated protocol(s).
For example, upon detection of the central line kit, the triggered central line infection prevention protocol may provide (e.g., via the safety protocol module 242 of
The process 400 then proceeds to step 412 wherein the safety protocol module 242 assigns the available care assets 120 identified in step 408 to the patient. To do so, for example, the safety protocol module 242 may provide an instruction to the care asset management system 230, which may further process the instruction and provide an indication to the hospital staff of which care assets 120 to be assigned to the patient. For example, in the example embodiment wherein the central line infection prevention protocol is implemented, a countdown alert for removal of the central line may be activated.
Further, the safety protocol includes a set of alerts that are to be set to ensure the safety of the patient. As such, the process 400 proceeds to step 414 to set one or more alerts based on the safety protocol. For example, in an embodiment wherein the patient has been identified as a falls risk, a falls prevention alert may be activated, or enabled. Activation of the falls prevention alert may further activate, or enable, a subset of alerts associated with the falls prevention alert, such as a toilet exit alert or a chair exit alert. To set, or activate, the alerts (i.e., to put the alerts into a monitoring state such that they can be alarmed if certain conditions are detected), at step 416, alerts can be set at a nurse call system, such as the nurse call system 210 of
The process 400 further proceeds to step 420 to monitor the health and outcomes of the patient. From step 420, the process 400 proceeds to step 422 to determine whether an alert was triggered. In other words, to determine whether a condition was detected such that the alert is in an alarmed state. If not, the process 400 returns to step 420 to continue to monitor the health and outcomes of the patient. Otherwise, if an alert has been triggered into an alarmed state, the process 400 proceeds to step 424, where alarms, or notifications, associated with the triggered alerts are activated. To do so, at step 426, the alarms may be activated at the nurse call system 210. Additionally or alternatively, at step 428, the alarms may be activated at the care asset 120. From step 428, the process 400 returns to step 420 to continue to monitor the health and patient outcomes.

In some embodiments, the process 500 may proceed from step 506 to step 508 to track care activities for the patient based on the safety protocol. The care activities may include any type of activity that is assigned to a staff member of the hospital based on the safety protocol. For example, a sub-protocol of a skin safety protocol may be a pressure ulcer prevention sub-protocol that may require a member of the hospital staff to regularly reposition the patient and/or perform a skin assessment, for example. In such embodiments, the care activities may be automatically tracked during rounding, or documented manually, such as by the hospital staff member in the EMR system 220 of
The process 500 then proceeds to step 510 to associate the care assets assigned to the patient with the patient. It should be appreciated that, in some embodiments, this functionality may be performed automatically, such as by the care asset management system 230 of
From step 514, the process 500 proceeds to step 516 to perform a statistical analysis between each of the patient outcomes and each of the care assets assigned to the patient. The statistical analysis may be used to determine whether a correlation and/or causation exist between the assigned care assets and the patient outcome. The process 500 then proceeds to step 518 to store the results of the statistical analysis before the process 500 proceeds to and terminates at step 520. In some embodiments, the results may be stored in the safety protocol database 244 of

From step 602, the process proceeds to step 604, wherein the safety protocol module 242 determines care asset information for those care assets 120 that are presently assigned to the patient in accordance with the safety protocol. As described previously, the care asset information may include a component usage history, a maintenance history, an assignment history, an illness exposure history, and the like. At step 606, the safety protocol module 242 determines care environment information relative to the patient. As also described previously, the care environment information may include any type of information indicative of the environment of the care assets 120 assigned to a patient, such as a location, a temperature level, a lighting condition, a pressure reading, a position setting, an alert setting, etc. Accordingly, the safety protocol module 242 may determine a location of the patient based on information relative to one of the care assets 120, such as based on a weight sensor of a hospital bed or a tracking device embedded on a wristband worn by the patient, for example.
For example, in an embodiment, the safety protocol module 242 may determine that the patient is presently under a particular prevention sub-protocol, is located in a particular room, and is being cared for with a particular model of hospital bed with a certain type of mattress on the hospital bed. It should be appreciated that, in some embodiments, the care environment information and/or the care asset information may be automatically transmitted to the safety protocol module 242; while, in other embodiments, the care environment information and/or the care asset information may be retrieved by the safety protocol module 242.
The process 600 proceeds to step 608, wherein the safety protocol module 242 determines whether the patient is exposed to a potential health risk. To do so, in some embodiments, at step 610, the safety protocol module 242 may compare the present safety protocol to the care asset information and/or the care environment information. Additionally or alternatively, in some embodiments, at step 612, the safety protocol module 242 may compare the care asset information and the care environment information to historical outcome information, such as the results of the statistical analysis performed by the safety protocol module 242 (see
The process 600 then proceeds to step 614 to determine whether the safety protocol module 242 has determined that the patient is exposed to a potential health risk. For example, in furtherance of the example embodiment with the patient under a pressure ulcer prevention protocol as described above, the patient may be compared to any number of other patients susceptible to pressure ulcers who also used the same model of hospital bed and/or the same type of mattress or sheets on the hospital bed. Accordingly, a percentage of the other patients that developed a pressure ulcer may be determined and compared to a threshold percentage. In such an embodiment, if the percentage of the other patients that developed a pressure ulcer exceeds the threshold percentage, the safety protocol module 242 may determine that the patient is exposed to a potential health risk.
Further, the safety protocol module 242 may determine a relationship between the patients that developed a pressure ulcer and the model of hospital bed, type of mattress, and/or type of sheet. In such an embodiment, the safety protocol module 242 may determine what woven sheets were assigned to a majority of the patients that developed a pressure ulcer. Accordingly, as will be discussed in further detail below, the woven sheets may be removed, or replaced with knit sheets, for those patients with an active skin care protocol to address pressure ulcers. In other words, the pressure ulcer prevention sub-protocol may be changed from assigning woven sheets to knit sheets and the existing pressure ulcer prevention sub-protocol patients that are assigned woven sheets scheduled to receive knit sheets, for example.
In another example, the safety protocol module 242 may determine the present safety protocol to be insufficient based on the comparison performed at block 610. In such an embodiment, the presence and/or use of (e.g., opening, prepping, administering, etc.) a care asset 120 may trigger one or more additional and/or alternative sub-protocols to be activated, thereby rendering the present safety protocol insufficient. For example, if a patient is determined to be in need of a lift after an existing safety protocol was enacted, one or more sub-protocols corresponding to care of the patient with respect to the lift may be activated. Similarly, for example, in an embodiment wherein a patient has not been identified as a falls risk and a member of the hospital staff sets an exit alarm for a patient support 122 (e.g., a hospital bed), one or more additional and/or alternative sub-protocols, such as the falls risk protocol, may be activated. Accordingly, as will be described in further detail below, alerts and/or care assets 120 may be adjusted based on the additional and/or alternative sub-protocols.
It should be appreciated that additional and/or alternative data may be used to further refine the results. In other words, the percentage of the other patients that developed a pressure ulcer may be further restricted by additional information consistent with the care assets presently assigned to the patient. For example, the percentage of the other patients that developed a pressure ulcer may increase if a portion of the other patients are removed based on one or more criteria, such as an age of the hospital bed or a number of uses of the mattress. Accordingly, the refined percentage may provide a more accurate representation of the health risk exposure. Similarly, certain alerts and/or care activities that were tracked for previous patients may influence the determined health risk exposure.
If the safety protocol module 242 has determined that the patient is not exposed to a health risk, the process 600 proceeds to step 628, wherein the process 600 terminates. Otherwise, if the safety protocol module 242 has determined that the patient is exposed to a potential health risk, the process 600 advances to step 616 to identify corrective actions based on the potential health risk exposure. To do so, in step 618, the safety protocol module 242 identifies available adjustments that can be made to the safety protocol, such as by changing alerts, care activities, a security level, etc., of the safety protocol. Additionally, in step 620, the safety protocol module 242 identifies which of the care assets 120 presently assigned to the patient can be changed based on the health risk and the care assets 120 that are available to be assigned to the patient. For example, the statistical analysis of the patient outcomes may determine a particular care asset 120 was assigned to several different patients, a percentage of which contracted an infection after coming into direct or indirect contact with that particular care asset 120.
From step 620, the process 600 proceeds to step 622 to make adjustments to the safety protocol based on the identified corrective actions at step 616. At block 624, the safety protocol module 242 adjusts the safety protocol based on the adjustments identified at step 618. To do so, the safety protocol module 242 may adjust the alerts at the nurse call system 210 and/or one or more of the care assets 120 that are capable of supporting alerts. It should be appreciated that the adjustments may be implemented manually or automatically, depending on the supported functionality of the care assets 120 affected by the adjustment to the safety protocol.
Additionally, at block 626, the safety protocol module 242 marks one or more assets to be changed that were identified at step 620. To do so, the safety protocol module 242 may provide an instruction to the care asset management system 230 that indicates that one or more care assets 120 to be changed. The process 600 then proceeds to step 628, wherein the process 600 terminates. Referring again to the particular care asset 120 that was assigned to several different patients, a percentage of which contracted an infection, may be marked as “out of service,” or otherwise scheduled for maintenance. Further, in some embodiments, the particular care asset 120 may be disabled, if the particular care asset 120 supports such a feature, such as in an embodiment wherein the particular care asset 120 is a pump that is not presently in use.
