Caregiver Availability Routing via Location Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In healthcare facilities, existing systems fail to efficiently route alert calls to available caregivers, often resulting in response delays due to the inability to accurately determine caregiver availability in real-time.
Innovation Solution
A system comprising locating tags worn by caregivers, transceivers, and a server that determines caregiver availability by tracking their location and status, allowing alert calls to be routed to the nearest available caregiver based on their proximity and role, while also considering the type of patient and room assignments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If alert calls are routed to caregivers without availability determination, then routing simplicity is maintained, but response time increases due to calling unavailable caregivers
Solution Approach 1:
The system performs preliminary determination of caregiver availability by tracking their current location and status before routing alert calls. The nurse call server queries the locating server to check if caregivers are available (not in patient care activities) before sending alert calls, preventing wasted calls to unavailable caregivers and reducing overall response time
Solution Approach 2:
The patent introduces an intermediary availability determination mechanism between the alert placement device and the caregiver. The nurse call server acts as a mediator that receives alert calls, determines caregiver availability through the locating server, and then routes calls appropriately, adding complexity but ensuring calls reach available caregivers
2Measurement precision
If caregiver availability is tracked using location data only, then system simplicity is maintained, but accuracy of availability determination deteriorates due to inability to distinguish actual availability status
Solution Approach 1:
The system merges location tracking data with caregiver status information from multiple sources (portable communication devices, nurse call system) to comprehensively determine availability. The nurse call server combines location data indicating caregiver presence in patient rooms with status data from portable devices where caregivers can designate themselves as unavailable, creating a more accurate availability determination
Solution Approach 2:
The system implements feedback mechanisms where caregivers can actively provide status information through portable communication devices, and the system continuously monitors location data to update availability status. This feedback loop ensures the availability determination reflects current conditions, with the nurse call server using this feedback to make informed routing decisions
3Productivity
If all caregivers are notified of alert calls, then ensuring coverage is maintained, but notification efficiency decreases due to unnecessary alerts to unavailable caregivers
Solution Approach 1:
The system applies different notification strategies based on local conditions - specifically the availability status of individual caregivers. Available caregivers receive alert call notifications, while unavailable caregivers are excluded from notifications. This localized approach to notification routing maintains reliability for available caregivers while improving overall efficiency by avoiding unnecessary notifications
Data Source
AI summary
A system and method to determine availability of caregivers to respond to nurse calls or other alerts originating in patient rooms is provided. Caregivers are designated as unavailable depending upon room types in which they are located, or depending upon patient types in the rooms in which they are located, or depending upon how long they have been present in certain rooms, or depending upon whether the caregivers have designated themselves as unavailable, or any combination of the foregoing. A system and method to escalate alerts to other caregivers if a primary caregiver is unavailable includes escalating first to a designated secondary caregiver and then to a caregiver who is closest in proximity to the room from which the alert originated if the secondary caregiver is also unavailable.
