Safety and Cost Savings Associated with Reduced Inpatient Hospitalization for Microvascular Decompression

OBJECTIVES: Microvascular decompression (MVD) has grown as a first-line surgical intervention for severe facial pain from trigeminal neuralgia and/or hemifacial spasm. We sought to examine the safety and cost-benefits of discharging patients with MVD within 1 day of admission. METHODS: We retrospectively reviewed patients undergoing MVD at our institution from 2008 to 2020. Patients were sorted by 1 day, 2 days, or >2 days until discharge and by year from 2008 to 2013, 2014 to 2018, or 2019 to 2020. Patient presenting characteristics, intraoperative measures, and complications were documented. Statistical differences were calculated by one-way analysis of variance and chi(2) analyses. RESULTS: Our cohort included 976 patients undergoing MVD, with 231 (23.6%) between 2008 and 2013, 517 (52.9%) between 2014 and 2018, and 228 (23.3%) between 2019 and 2020. Over time, postoperative admission rates to the critical care unit, total inpatient hospital admission times, and Barrow Neurological Institute scores at first follow-up decreased. Postoperative complications, including cere-brospinal fluid leak, decreased significantly. In addition, patients discharged within 1 day of admission incurred a total hospital cost of $26,689, which was $3588 lower than patients discharged within more than 1 day of admission, P < 0.0001. Discharging carefully selected patients who are appropriate for discharge within 1 day of admission could translate to a potential cost-savings of $255,346 per year in our clinical practice. CONCLUSIONS: In our experience, MVDs are a safe, elective intervention. Our findings suggest that postoperative day 1 discharge in patients with an uncomplicated postoperative course may be safe while improving hospital resource use.

Automated summary

This study examined the safety and cost-benefits of discharging patients with microvascular decompression (MVD) within 1 day of admission for severe facial pain. The results showed that discharging carefully selected patients within 1 day of admission was safe and resulted in reduced hospital admissions, complications, and total hospital costs.
