Patient outcomes following ambulatory anesthesia.

As the number and type of surgeries performed in the ambulatory setting have increased, outcomes research has allowed for better analysis of the safety and efficacy of care given to patients. Though this once involved measures of clinical morbidity and mortality alone, researchers have begun to focus their attention beyond these end points and take into account patients' postoperative functional status and satisfaction as a way to assess the overall quality of patient care. Also key in this move to a more global assessment of health care interventions has been an increased focus on economic outcomes. As new anesthetic drugs and techniques continue to develop, outcomes research will continue to evolve in new directions, providing further information for improvements in patient care.
