Applications of enhanced recovery after surgery protocols for unruptured anterior circulation aneurysms in tertiary-level healthcare institutions: a national study.

OBJECTIVE: Enhanced recovery after surgery (ERAS) protocols are standardized perioperative care that reduce patients' stress response during hospitalization and improve hospitalization time, complication rates, costs, and readmission rates. This study aimed to investigate the application rate of protocols for elective craniotomy in the surgery of unruptured anterior circulation aneurysms (AnCAs) at tertiary-level healthcare (TLH) institutions in Türkiye and its effect on the outcomes of the patients. METHODS: An electronic survey was sent to all Turkish TLH institutions (n = 127) between May and June 2023. The number of institutions participating in the survey was 38 (30%). The institutions were subdivided according to three main factors: institution type (university hospital [UH] vs training and research hospital [TRH]), annual case volume (low [≤ 20 aneurysms] vs high [> 20 aneurysms]), and institution accreditation status (accredited vs nonaccredited). RESULTS: Overall, 55.3% (n = 21) of the institutions participating in the study were UHs. The rates of those that were accredited and had a high case volume were 55.3% (n = 21) and 31.6% (n = 12), respectively. It was determined that the accredited clinics applied preoperative protocols at a higher rate (p = 0.050), and the length of stay in the postoperative period was shorter in the clinics that used the intraoperative protocols (p = 0.014). CONCLUSIONS: The length of stay in the postoperative period is lower in TLH institutions in Türkiye that highly implement intraoperative protocols. Furthermore, this is the first study in the literature evaluating protocols for elective craniotomy in unruptured AnCAs.
