An Audit of Level Two and Level Three Checks of Anaesthesia Delivery Systems Performed at Three Hospitals in South Australia

Abstract

Anaesthetists may subject patients to unnecessary risk by not checking anaesthetic equipment thoroughly before use. Numerous adverse events have been associated with failure to check equipment. The Australian and New Zealand College of Anaesthetists and anaesthetic delivery system manufactures have made recommendations on how anaesthetic equipment should be maintained and checked before use and for the training required for staff who use such equipment. These recommendations are made to minimise the risk to patients undergoing anaesthesia. This prospective audit investigated the adherence of anaesthetic practitioners to a selection of those recommendations. Covert observations of anaesthetic practitioners were made while they were checking their designated anaesthetic machine, either at the beginning of a day's list or between cases. Structured interviews with staff who check the anaesthetic machine were carried out to determine the training they had received. The results indicated poor compliance with recommendations: significantly, the backup oxygen cylinders’ pressure/contents were not checked in 45% of observations; the emergency ventilation device was not checked in 67% of observations; the breathing circuit was not tested between patients in 79% of observations; no documentation of the checks performed was done in any cases; and no assessment or accreditation of the staff who performed these checks was performed. It was concluded that the poor compliance was a system failing and that patient safety might be increased with training and accrediting staff responsible for checking equipment, documenting the checks performed, and the formulation and use of a checklist.

Development, implementation and impact of simple patient safety interventions in a university teaching hospital

“…It has been documented that checks are not always conducted with the recommended protocol (Sweeney et al. ). Finally, the changes in proportion of incidents may be due to another variable which was not recorded, such as increased communication among students, staff, and clinicians (Haynes et al.…”

Clinical Audit on Current Practice of Anesthesia Machine Check and Equipment Preparedness Before Use in Debre Berhan Comprehensive Specialized Hospital, North Shewa, Ethiopia, 2020

“…Anesthesia services are performed in diverse and complex settings which need per case preparation and checking of equipment before use. 1,10 Anesthetists accomplish many tasks rapidly during induction of anesthesia, so the intense environment of the operating room, preparatory steps may be missed either unintentionally or possibly even intentionally to save time during emergency surgical procedures. 2 A Prospective study on anesthesia machine fault identification demonstrated that anesthesia machine check and equipment preparation before use continues to be a problem in the most operation room.…”

Revalidation: Implications for Australian Anaesthetists

“…However, there is only a limited literature on the care provided by specialist anaesthetists, with much of it limited to small, single-centre studies focused on process outcomes rather than patient ones. For example, the quality of documentation by Australian anaesthetists varies 61 , as does adherence to guidelines for checking the anaesthesia machine 62 , sampling from arterial lines 63 and perioperative management of anticoagulant and antiplatelet drugs 64 .…”
