Temporal trends and risk factors of hospital readmission following deep brain stimulation for Parkinson disease

Background: Risk factors and long-term data on readmissions following deep brain stimulation (DBS) for Parkinson Disease (PD) remain unclear. Objective: To evaluate the temporal trend and risk factors associated with hospital readmission following DBS for PD. Methods: We analyzed DBS procedures for PD in the National Readmissions Database (2016–2022). The association between demographic, clinical, and hospital factors with 90-day readmission following DBS was evaluated using a multivariable logistic and Cox regression models. Results: Among 7535 DBS surgeries, 8.1 % individuals were readmitted within 90 days. Higher Elixhauser-Comorbidity Index and complicated diabetes mellitus were associated with a higher risk of 90-day readmission (adjusted odds ratio 1.60, 95 % CI 1.06–2.41). Readmissions did not statistically significantly change between 2016 and 2022. Conclusion: The rate of non-elective readmissions following DBS for PD has not changed over time. A higher comorbidity index and complicated diabetes mellitus were identified as key risk factors.
