Enhanced recovery after elective spinal and peripheral nerve surgery: pilot study from a single institution

Restricted access

OBJECTIVE

Enhanced recovery after surgery (ERAS) protocols address pre-, peri-, and postoperative factors of a patient’s surgical journey. The authors sought to assess the effects of a novel ERAS protocol on clinical outcomes for patients undergoing elective spine or peripheral nerve surgery.

METHODS

The authors conducted a prospective cohort analysis comparing clinical outcomes of patients undergoing elective spine or peripheral nerve surgery after implementation of the ERAS protocol compared to a historical control cohort in a tertiary care academic medical center. Patients in the historical cohort (September–December 2016) underwent traditional surgical care. Patients in the intervention group (April–June 2017) were enrolled in a unique ERAS protocol created by the Department of Neurosurgery at the University of Pennsylvania. Primary objectives were as follows: opioid and nonopioid pain medication consumption, need for opioid use at 1 month postoperatively, and patient-reported pain scores. Secondary objectives were as follows: mobilization and ambulation status, Foley catheter use, need for straight catheterization, length of stay, need for ICU admission, discharge status, and readmission within 30 days.

RESULTS

A total of 201 patients underwent surgical care via an ERAS protocol and were compared to a total of 74 patients undergoing traditional perioperative care (control group). The 2 groups were similar in baseline demographics. Intravenous opioid medications postoperatively via patient-controlled analgesia was nearly eliminated in the ERAS group (0.5% vs 54.1%, p < 0.001). This change was not associated with an increase in the average or daily pain scores in the ERAS group. At 1 month following surgery, a smaller proportion of patients in the ERAS group were using opioids (38.8% vs 52.7%, p = 0.041). The ERAS group demonstrated greater mobilization on postoperative day 0 (53.4% vs 17.1%, p < 0.001) and postoperative day 1 (84.1% vs 45.7%, p < 0.001) compared to the control group. Postoperative Foley use was decreased in the ERAS group (20.4% vs 47.3%, p < 0.001) without an increase in the rate of straight catheterization (8.1% vs 11.9%, p = 0.51).

CONCLUSIONS

Implementation of this novel ERAS pathway safely reduces patients’ postoperative opioid requirements during hospitalization and 1 month postoperatively. ERAS results in improved postoperative mobilization and ambulation.
