Procedural errors and clinical mistakes are frequently reported in veterinary medicine. Such can have detrimental effects on patient safety, trust between caregivers, and client confidence. The severity of the event may also cause professional, financial, and legal outcomes. Frequently, negative events can be reduced to common risks that predisposed the error; and sometimes it is just a “perfect storm of events” which by themselves were harmless. This session examines those etiologies and how they affect the practice’s culture. Learning Objectives: 1. How to recognize the early sentinels of mistakes yet to occur. 2. To understand the scope of potential consequences of negative events 3. How to proceed once the team recognizes the incident.
