Low Norton Scale Score Predicts Worse Outcomes for Parkinson’s Disease Patients Hospitalized Due to Infection

Background:Parkinson's disease (PD) patients are prone to infections leading to hospitalization. We used the Norton Scale score (NSS) as a prognostic tool for these patients. Method: Retrospective analysis of consecutive PD patients, all had NSS appreciation upon admission. Analyses were made to establish the association between NSS upon admission, short-term, and long-term clinical outcomes. Results: Five hundred twenty-eight PD patients' records were reviewed, of which 81 were eligible for analysis. Patients who died during hospitalization had a significantly lower NSS (10.0 vs. 13.1, p = .026). Among surviving patients, those who were discharged to more intensive care facilities relative to their original place of arrival also had a significantly lower NSS (10.38 vs. 13.63, p = .0002). Lower NSS was found to increase the risk for 1-year mortality (odds ratio = 1.3; 95% confidence interval = [1.09, 1.56], p = .003). Conclusion: Lower NSS upon admission of PD patients, suffering from infection is associated with worse clinical outcomes.
