Critical failures in the use of home ventilation medical equipment

A multidisciplinary team performed an extended version of Failure Mode, Effect and Criticality Analysis (FMECA) to analyse the home ventilation service provided by the Local Healthcare Unit of Naples (ASL NA1) that assisted 60 homebound ventilator dependent patients. The failures were identified in three risk areas: device, electrical system & fire hazard, and indoor air quality. The corrective actions were formulated with two extra steps: identification of critical failures with a threshold applied to the risk priority number and analysis of causes by means of contributory factors (Organization, Technology, Information, and Structure) based on Reason's theory of failures.

Home ventilation involves the use of medical devices at patient's home by personnel who are not healthcare practitioners. This implies new potential risks not fully addressed by current standards and guidelines. A methodological approach to investigate potential failures and define improvement actions to address the dangerous potential situations in HV is required.
