The Standardization of Outpatient Procedure (STOP) Narcotics after anorectal surgery: a prospective non-inferiority...

Prescription of opioid medication after ambulatory anorectal surgery may be excessive and lead to opioid misuse. The purpose of this study was to evaluate the efficacy of a multi-modality opioid-sparing approach to control postoperative pain and reduce opioid prescriptions after outpatient anorectal surgery.

A prospective non-inferiority pre- and post-intervention study was completed at three academic hospitals. Patients included were 18-75 years of age who had outpatient anorectal surgeries. The Standardization of Outpatient Procedure (STOP) Narcotics intervention was implemented, which is a multi-pronged analgesia bundle integrating patient education, health care provider education, and intra-/postoperative analgesia focused on multi-modal pain control strategies and opioid-reduced prescriptions. The primary outcome was patient-reported average pain in the first 7 postoperative days. Secondary outcomes included patient-reported quality of pain management, medication utilization, prescription refills and medication disposal.

Ninety-three patients had outpatient anorectal surgery (42 pre-intervention and 51 post-intervention). No difference was seen in average postoperative pain in the pre- vs. post-intervention groups (2.8 vs. 2.6 on an 11-point scale, p = 0.33) or patient-reported quality of pain control (good/very good in 57% vs. 63%, p = 0.58). The median oral morphine equivalents (OME) prescribed was significantly less [112.5 (IQR 50-150) pre-intervention vs. 50 (IQR 50-50) post-intervention, p < 0.001]. In the post-intervention group, only 45% of patients filled their opioid prescription and median opioid use was 12.5 OME (2.5 pills).

While pain control after anorectal surgery must consider the individual patient's needs, a standardized pain care bundle significantly decreased opioid prescribing without an increase in patient-reported postoperative pain.
