Skilled nursing facility patient triage system
The present disclosure pertains to a system for facilitating computer-assisted care for patients, including, for example, skilled nursing facility (SNF) patients at risk of clinical deterioration and/or in need of medical intervention relative to a larger SNF patient population. In some embodiments, the system determines care information scores for SNF patients using a first set of severity weights associated with individual components of the care information. The system determines SNF enhancement scores for the individual patients using a second set of severity weights associated with individual components of collected SNF enhancement information, wherein the second set of severity weights are heavier than the first set of severity weights such that the enhancement scores are weighted more heavily than the care information scores. The system combines the care information scores with the enhancement scores for patients to determine a combined score indicating risk of clinical deterioration and/or need for medical intervention. |

Integration of a point-of-care blood analyzer into a prehospital telemedicine system
A prehospital telemedicine system comprises a physiologic monitor; an electronic patient care reporting system (ePCR) system; and a point-of-care blood analyzer communicatively coupled to the physiologic monitor and the ePCR system. The point-of-care blood analyzer is configured to perform an analysis of a blood sample based on an indication of a need for a specific blood analysis provided by one of the physiologic monitor and the ePCR system, and to automatically transmit a result of the analysis to a remote data receiving system. The indication of a need for a specific blood analysis may be based upon any one of the following: vital signs data obtained for a patient by the physiologic monitor; and/or current documentation or past medical history captured on or available through the ePCR system. |

Converting pump messages in new pump protocol to standardized dataset messages
Various techniques for facilitating communication with and across a clinical environment and a cloud environment are described. For example, a method for converting infusion pump messages having one format into standardized dataset messages having another format is described. When a connectivity adapter in the clinical environment detects a new pump protocol, the connectivity adapter may generate a message converter that can convert pump messages into standardized dataset messages. The message converter can be used to convert pump messages into standardized dataset messages. The standardized dataset messages may include information additional data or metadata not included in the pump messages. |
