For many years, the process of abstracting patient data after Sentinel Events has been challenging. Say for instance, an adverse patient event occurred, but despite the patient being on telemetry monitoring, the only physiological data available might be ECG strips, if those had even been captured. Most modern patient monitoring systems rarely record more than 144 hours of data. Excel Medical Systems came out with the “Bedmaster” platform several years ago to allow hospitals to save patient monitoring data indefinitely, (or to the limit of disk capacity on an allocated network drive). With their proprietary zero-loss compression algorithm, they can store 24 hours of patient data in just ~200 MB of disk space per day. The software sits on a physical or virtual server and just “listens” to the data passing by on the network and saves it to a database, where it can be mined via SQL, or simply played back like a DVD.
The saved data can be replayed, along with alarms and any peripheral data stored from ventilators, and infusion pumps etc., so that you can recreate the entire scenario, or use for research purposes. The system also supports real-time high-resolution video. It’s a useful tool for re-creating what happened leading up to a Sentinel Event, as you can view retrospective including waveforms and alarm events. The system works with either GE or Philips patient monitoring systems and can embed the waveform view directly in an EMR system contextually.
Such a system completely eliminates the guesswork of what happened as it can replay the entire event months and even years later. The SQL back-end allows for Root Cause Analysis and development of powerful multivariate analysis tools which can include waveforms for Heart Rate Variability that can further be used for sepsis or patient degradation analysis.
