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.
