Development and implementation of veterinary anesthesia medical quality standards for primary care

Objective: The provision of general anesthesia is common in veterinary hospitals and procedures include some level of risk, up to and including mortality. A quality initiative was introduced with a focus on reducing canine and feline anesthesia mortality. This paper describes the development and implementation of risk-based medical quality standards (MQS) and resultant impacts on anesthesia mortality.

Study design: This was a qualitative observational study. MQS focused on the provision of anesthesia were researched, developed and implemented. Anesthesia mortality rates, captured via an automated process based on the electronic medical record, were recorded before and after implementation. Compliance to standards was determined via hospital auditing.

Animals: Client-owned dogs and cats presenting to Banfield Pet Hospital (a national network of primary care hospitals) for elective and nonelective general anesthesia procedures. Over the course of the study, 2,038,318 dogs and 350,410 cats had a general anesthesia event.

Methods: Literature reviews and analysis of veterinary patient medical records identified risk factors associated with anesthesia mortality. Risk factors informed the development of MQS. Evidence-based standards focused on the provision of general anesthesia were written, reviewed, evaluated and edited. Implementation occurred over 6 months via a robust communication plan. Anesthesia mortality rates were continuously monitored before, during and after the introduction of standards. Compliance with all quality standards was assessed via hospital-based auditing performed on an annual basis.

Results: Prior to quality standards implementation, anesthesia mortality rates for dogs and cats combined was 7.4 deaths/10,000 procedures. At 6 months after implementation, the mortality rate was 6.24 deaths/10,000 procedures, representing a 16% decrease. Compliance with standards improved over time with continued focus and education.

Conclusions and clinical relevance: Development, implementation and continued focus on MQS can improve anesthetic safety and reduce anesthesia mortality in primary care veterinary hospitals.
