Analysis of Unplanned Return to the Operating Room Within 30 Days of Initial Neurosurgery: A 3-Year Experience at a Single Center

Abstract

Objective: The goal of this study was to evaluate the reasons and prognosis of unplanned return to the operating room (URTOR) and to help improve neurosurgical service quality.

Methods: Medical records of URTOR within 30 days of initial surgery were reviewed at a single neurosurgical center for a period of 3 years. Out of 4516 neurosurgeries, 62 URTOR cases were included to analyze patients' age, sex, initial surgery code, seniority of the performed surgeon, interval between the reopening procedures and initial procedures, reason for reopening, prognosis, and complications.

Results: The 62 patients underwent 70 URTORs. Out of 1445 primary operations performed by junior surgeons, 40 experienced URTOR, whereas 22 of 3071 craniotomies initially performed by senior surgeons resulted in URTOR. Five patients died in this series. Out of the 54 patients who experienced 1-time URTOR, 3 died, whereas 2 of the 8 patients who experienced 2-time URTOR died. Of 22 URTOR surgeries performed by senior surgeons, 10 took place within 24 hours, compared with 26 out of 48 performed by the junior surgeon.

Conclusions: The main reasons for URTOR after neurosurgery were rebleeding and swelling of the brain. The number of URTORs and time from primary craniotomy to URTOR are not associated with morbidity or mortality. However, the seniority of the surgeon affects the rate of URTOR: surgeons with rich experience in surgery may reduce the chance of a second craniotomy and increase the chance of a good prognosis.
