Sorting it by department shows where the problems may be. Any fall is cause for concern, but note how different it is to see falls in Rehab compared to falls in X-ray. Virtually any fall in X-ray is a major event. It becomes evident that an effective Incident Reporting system is complex, receiving data, and producing various reports on a monthly basis. The last datum needed to fully exploit the incident data is the cause' of the events.
Causes are so diverse that a small number of cause categories is inadequate.
Finding causes is actually the major purpose of any investigation. Causes are multifaceted, deriving from complex systems that enable incident to occur. Only an investigation will sort out the contributing factors that often cross department lines. It is interesting that only a small percentage of the serious events result in legal action. I tracked major events by patient name for many years.
