Safety and costs analysis of early hospital discharge after brain tumour surgery: a pilot study.

Background: A daily algorithm for hospital discharge (DAHD) is a key point in the concept of Enhanced Recovery After Surgery (ERAS) protocol. We aimed to evaluate the length of stay (LOS), rate of complications, and hospital costs variances after the introduction of the DAHD compared to the traditional postoperative management of brain tumour patients.

Methods: This is a cohort study with partial retrospective data collection. All consecutive patients who underwent brain tumour resection in 2017 were analysed. Demographics and procedure-related variables, as well as clinical outcomes, LOS and healthcare costs within 30 days after surgery were compared in patients before/pre-implementation and after/post-implementation the DAHD, which included: stable neurological examination; oral feeding without aspiration risk; pain control with oral medications; no intravenous medications. The algorithm was applied every morning and discharge was considered from day 1 after surgery if criteria was fulfilled. The primary outcome (LOS after surgery) analysis was adjusted for the preoperative performance status on a multivariable logistic regression model.

Results: A total of 61 patients were studied (pre-implementation 32, post-implementation 29). The baseline demographic characteristics were similar between the groups. After the DAHD implementation, LOS decreased significantly (median 5 versus 3 days; p = 0.001) and the proportion of patients who were discharged on day 1 or 2 after surgery increased (44.8% vs 3.1%; p < 0.001). Major and minor complications rates, readmission rate, and unplanned return to hospital in 30-day follow-up were comparable between the groups. There was a significant reduction in the median costs of hospitalization in DAHD group (US$2135 vs US$2765, p = 0.043), mainly due to a reduction in median ward costs (US$922 vs US$1623, p = 0.009).

Conclusions: Early discharge after brain tumour surgery appears to be safe and inexpensive. The LOS and hospitalization costs were reduced without increasing readmission rate or postoperative complications.
