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 costebenefits of discharging patients with MVD within 1 day of admission.METHODS: We retrospectively reviewed patients un-dergoing 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 mea-sures, and complications were documented. Statistical differences were calculated by one-way analysis of vari-ance and c2 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 crit-ical 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 post-operative day 1 discharge in patients with an uncompli-cated postoperative course may be safe while improving hospital resource use.

Automated summary

Microvascular decompression (MVD) is an effective surgical intervention for severe facial pain, and discharging carefully selected patients within 1 day post-operation can lead to cost savings without compromising patient outcomes.
