Retrospective medical record evaluation: Reliability in assessing causation, preventability, and disability of adverse events

Purpose – The purpose of this article is to assess the reliability of an in‐depth analysis on causation, preventability, and disability by two separate review teams on five selected adverse events in acute hospitals: pressure ulcer, postoperative pulmonary embolism or deep vein thrombosis, postoperative sepsis, ventilator‐associated pneumonia and postoperative wound infection.Design/methodology/approach – The analysis uses a retrospective medical record review of 1,515 patient records by two independent teams in eight acute Belgian hospitals for the year 2005. The Mann‐Whitney U‐test is used to identify significant differences between the two review teams regarding occurrence of adverse events as well as regarding the degree of causation, preventability, and disability of found adverse events.Findings – Team 1 stated a high probability for health care management causation in 95.5 per cent of adverse events in contrast to 38.9 per cent by Team 2. Likewise, high preventability was considered in 83.1 per cen...
