A cross-sectional study of preoperative medication adherence and early postoperative recovery

This study taken together with accruing evidence suggests that preoperative medication omission remains an ongoing issue that can influence complication rates in the PACU. Patients with preoperative conditions stay longer in PACU, and medication omission was associated with higher rates of certain postoperative complications in PACU. This identifies patients likely to require more interventions and greater recovery resources. Further research into the impact of medication omission on recovery parameters after discharge from the PACU is warranted.
