Abstract
For many years the classical approach to healthcare incident investigation has been Root Cause Analysis (RCA). However, healthcare has faced increasing criticism for failing to learn from when things go wrong and for investigations that are ineffective. There is a need to better support healthcare staff, who may have limited training and experience in investigation, to undertake more effective patient safety investigations. The authors aimed to identify an appropriate and usable patient safety investigation method for use by healthcare staff. The result of a literature review and engagement with experts led the authors to focus on the Human Factors Analysis and Classification System (HFACS) and AcciMap. Prior to evaluating the methods, HFACS was adapted to the acute hospital context by developing a coding set based on the original codes. Through workshops the authors identified a clear preference for HFACS. Its prescriptive nature appealed to investigators in that it considered all aspects of their systems and highlighted the potential contributory factors; it was felt to have face and content validity. HFACS presents a much-needed prescriptive model for investigators from varying backgrounds and experience. It is usable, appropriate, valid and reliable. The HFACS codes may require further development for different contexts, having been developed here for acute hospitals.
