Systematic Review of Enhanced Recovery After Surgery in Patients Undergoing Cranial Surgery

Enhanced Recovery after Surgery (ERAS) pathways are increasingly being integrated in neurosurgical patient management. The full extent of ERAS in cranial surgery is not well studied. We performed a systematic review examining ERAS in cranial surgery patients to 1) identify the extent to which ERAS is integrated in cranial neurosurgical procedures and 2) assess effectiveness of ERAS interventions for patients undergoing these procedures.

A systematic review of MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, Scopus, PsychInfo, and Google Scholar was conducted according to PRISMA guidelines (CRD42020197187). Studies eligible for inclusion assessed patients undergoing any cranial surgical procedure using an ERAS or ERAS-like pathway, defined by ≥2 ERAS protocol elements per the ERAS Society's RECOvER Checklist and the recommendations of Hagan et al. 2016 (not including patient education, criteria for discharge, or tracking of postdischarge outcomes).

Nine studies were included in qualitative synthesis, 2 of which were randomized controlled trials. All studies showed a moderate risk of bias. The most common ERAS elements used were screening and/or optimization and formal discharge criteria. The least common ERAS elements used were fasting/carbohydrate loading and antithrombotic prophylaxis. Complication rates were similar in studies comparing ERAS with non-ERAS groups. ERAS interventions were associated with reduced length of stay, with comparable and/or improved patient satisfaction.

ERAS is a safe and potentially favorable perioperative pathway for select patients undergoing cranial surgery. Future studies of ERAS in cranial surgery patients should emphasize postoperative optimizations and patient-reported outcome measures as key features.
