AMBULATORY ANESTHESIA: Edited by J. Lance Lichtor

Purpose of review: To summarize the currently available data on malpractice claims related to ambulatory anesthesia and provide an insight into the emerging patterns of anesthesia liability in this practice setting.

Recent findings: At present, studies are mixed about how the continued growth of outpatient surgery will impact liability for anesthesiologists. Data derived from the ASA Closed Claims Project suggests that malpractice claims for major damaging events are less common in the outpatient settings than in inpatient settings. Correspondingly, the payment amounts for outpatient claims are significantly lower than those for inpatients. Nevertheless, nondisabling adverse events are common and involve respiratory, cardiac, equipment-related, and drug errors. In addition, the vast majority of injuries in outpatient claims was the result of substandard care and judged preventable by better monitoring. Although major incidents leading to malpractice suits are less, new liability exposure may be on the horizon, due to the changing landscape of ambulatory practice that permits care for sicker patients who require more complex surgeries. The areas of potential concern include postoperative discharge criteria, care for the obstructive sleep apnea patient, and the choice of anesthetic techniques such as neuraxial blocks and monitored anesthesia care.

Summary: With steady increase in outpatient surgery, anesthesiologists are confronted with new areas of liability. More data are needed to identify these risks and reduce exposure to malpractice claims.
