Impact of Management Strategies on New-Onset Mental Health Disorders and Associated Health Care Utilization in Patients with Vestibular Schwannoma
World neurosurgery(2023)
Abstract
OBJECTIVE:To compare the impact of different management strategies on diagnosis of new-onset mental health disorders (MHDs) in patients with vestibular schwannoma (VS) and health care utilization at 1-year follow-up. METHODS:MarketScan databases were queried using the International Classification of Diseases, Ninth Revision and Tenth Revision and Current Procedural Terminology, Fourth Edition, 2000-2020. We included patients ≥18 years old with a diagnosis of VS who underwent clinical observation, surgery, or stereotactic radiosurgery (SRS) with at least 1 year of follow-up. We looked at health care outcomes and MHDs at 3-month, 6-month, and 1-year follow-up. RESULTS:The database search identified 23,376 patients. Of these, 94.2% (n = 22,041) were managed conservatively with clinical observation at the initial diagnosis, and 2% (n = 466) underwent surgery. The surgery cohort had the highest incidence of new-onset MHDs followed by SRS and clinical observation cohorts at 3 months (surgery: 17%; SRS: 12%; clinical observation: 7%), 6 months (surgery: 20%; SRS: 16%; clinical observation: 10%), and 12 months (surgery: 27%; SRS: 23%; clinical observation: 16%) (P < 0.0001). The median difference in combined payments between patients with and without MHDs was highest in the surgery cohort followed by SRS and clinical observation cohorts at all time points (12 months: surgery: $14,469; SRS: $10,557; clinical observation: $6439; P = 0.0002). CONCLUSIONS:Compared with clinical observation only, patients who underwent surgery for VS were 2 times more likely and patients who underwent SRS were 1.5 times more likely to develop MHDs with corresponding increase in health care utilization at 1-year follow-up.
