['Many institutions have organized specialized groups of ambulatory surgery anesthesiologists with the aim of improving ambulatory surgery patient care and efficiency. We hypothesized that specialized ambulatory anesthesia teams produce better patient outcomes such as lower postoperative nausea and vomiting (PONV) rates, lower postoperative pain scores, and shorter postanesthesia care unit (PACU) lengths of stay (LOS).', 'In this prospective observational study, we collected outcomes data on 1,299 patients including incidence of PONV, PACU LOS, maximum and average pain scores, amount of postoperative opioid use, and rescue antiemetic use.', 'Ambulatory anesthesiologists had statistically shorter phase 2 PACU LOS times (P < .05) and overall recovery times (P < .01). The PONV incidence odds ratio for ambulatory versus nonambulatory anesthesiologists was 1.31 (95% CI 1.01-1.72). We found no significant difference in the amount of postoperative opioid use, maximum postoperative pain scores, or PACU phase 1 LOS time.'] Do specialized ambulatory anesthesia teams contribute to decreased ambulatory surgery recovery room length of stay?
