PurposeChronic pain is a common condition affecting almost one in five Canadians. One of the methods used to treat chronic pain is injection therapies. While they are considered relatively safe procedures, they do carry inherent risk that can result in adverse events. Our goal was to investigate these patient safety events to identify themes that could be used to shape practice guidelines and standards and improve patient safety.MethodsWe looked at closed civil legal actions and regulatory college complaints associated with injection therapies for chronic pain in the Canadian Medical Protection Association database from 2015 to 2019. Injury was defined as that arising from, or associated with, plans or actions taken during the provision of health care, rather than an underlying disease or injury.ResultsOf the 91 cases identified, the most common reported complications were neurologic-related symptoms, injury, and infection. Fifty-eight percent (53/91) of patients experienced health care-related harm that had a negative effect on their health or quality of life. Peer experts were critical of the clinical care provided in 74% (67/91) of the cases. Provider-related (60%, 40/67), team-related (75%, 50/67), and system-related factors (21%, 14/67) were identified as contributing factors in these cases. Common examples of provider-related factors were deficiencies in clinical decision-making (48%, 19/40), failure to follow established procedures (43%, 17/40), and situational awareness (38%, 15/40). Common examples of team-related factors were deficiencies in medical record keeping (80%, 40/50) and communication breakdowns (56%, 28/50). All system-related factors were related to inadequate office procedures.ConclusionWe recommend that clinicians conduct appropriate physical examinations, keep up-to-date with clinical standards, and ensure their documentation reflects their assessment, the patient's condition, and the treatment rationale.© 2023.
