Hypothesis: Health care failure mode and effect analysis identifies critical processes prone to information transfer and communication failures and suggests interventions to improve these failures.
Design: Failure mode and effect analysis.
Setting: Academic research.
Participants: A multidisciplinary team consisting of surgeons, anesthetists, nurses, and a psychologist involved in various phases of surgical care was assembled.
Main Outcome Measures: A flowchart of the whole process was developed. Potential failure modes were identified and evaluated using a hazard matrix score. Recommendations were determined for certain critical failure modes using a decision tree.
Results: The process of surgical care was divided into the following 4 main phases: preoperative assessment and optimization, preprocedural teamwork, postoperative handover, and daily ward care. Most failure modes were identified in the preoperative assessment and optimization phase. Forty-one of 132 failures were classified as critical, 26 of which were sufficiently covered by current protocols. Recommendations were made for the remaining 15 failure modes.
Conclusions: Modified health care failure mode and effect analysis proved to be a practical approach and has been well received by clinicians. Systematic analysis by a multidisciplinary team is a useful method for detecting failure modes.
