Session Time: 12:30pm-2:00pm
Location: Exhibit Hall located in Hall B, Level 2
Objective: (1)To study what comorbid conditions were present at baseline and 3 years later in a cohort of Spanish PD patients and (2) to analyze the role of comorbidity as predictor of mortality.
Background: Parkinson´s disease (PD) is accompanied by significant comorbidity and that both the extent and type of comorbidity vary as a function of PD duration and age at symptoms onset. Comorbidity should be taken into consideration in the management of the disease.
Methods: One hundred and forty nine non-demented PD patients (57 % males; 70.9 ± 8.6 years old) were included in this 36 months follow-up, longitudinal, monocenter, evaluation study. The International Classification of Diseases, Tenth Revision (ICD-10), Charlson Index (CI), Comorbidity-Polypharmacy Score (CPS) and Elixhauser Comorbidity Measure (ECM) were used to asses comorbidity at baseline and at 3 years.
Results: Seventeen patients died and 8 cases were loss to follow-up. Diseases of the circulatory system (ICD-10/chapter-IX) and endocrine, nutritional and metabolic diseases (ICD-10/chapter-IV) were the most frequent at baseline (53.7% and 51.7%, respectively) and at 3 years (57.3% and 58.1%, respectively). According to ECM, hypertension was the most frequent comorbidity at baseline and at 3 years (41.6% and 46%, respectively). A significant increase in comorbidity was observed at 3 years (n=124): ICD-10 (total number of comorbidities), 5.9 ± 3.8 vs 4.1 ± 1.9 (p<0.001); CI, 0.9 ± 1.4 vs 0.5 ± 0.9 (p<0.001); CPS, 12.4 ± 5.3 vs 9.9 ± 4.1 (p<0.001). Total number and severity of comorbidities at baseline were higher in patients who died (n=141): ICD-10, 5.7 ± 3.3 vs 4.1 ± 1.9 (p=0.006); CI, 1.4 ± 1.6 vs 0.5 ± 0.9 (p=0.001); CPS, 12.7 ± 6.1 vs 9.9 ± 4.1 (p=0.017). Comorbidity was a predictor of death after other covariates adjustment: ICD-10 (total number of comorbidities), hazard ratio 1.261 (95% confidence interval, 1.043-1.524; p=0.017); CI, hazard ratio 1.454 (95% confidence interval, 1.043-2.027; p=0.027).
Conclusions: Comorbidity is frequent in PD patients, increases significantly over time and predicts mortality.
