Category: Parkinson's Disease: Non-Motor Symptoms
Objective: The aim of the present study was to identify predictors of clinically significant quality of life (QoL) impairment in Parkinson´s disease (PD) patients from a Spanish cohort.
Background: It is important in clinical practice to know what factors contribute to a worsening of the QoL of PD patients with the intention of being able to carry out interventions.
Method: PD patients recruited from 35 centers of Spain from the COPPADIS cohort from January 2016, to November 2017, were followed-up during 2 years [1]. Health-related QoL (HRQoL) and global QoL (GQoL) were assessed with the 39-item Parkinson’s disease Questionnaire (PDQ-39) and the EUROHIS-QOL 8-item index (EUROHIS-QOL8), respectively, at baseline (V0) and at 24 months ± 1 month (V2). Clinically significant HRQoL and GQoL impairment were defined as presenting an increase and decrement in PDQ-39SI and EUROHIS-QOL8 score at V2 ≥ 10% of the score at baseline (V0), respectively [2]. A comparison with a control group was conducted for GQoL.
Results: GQoL didn´t change significantly neither in PD patients (N=507; p=0.686) nor in the control group (N=119; p=0.192). The mean PDQ-39SI was significantly increased in PD patients (62.7 ± 8.5 years old; 58.8% males; N=500) by 21.6% (from 16.7 ± 13 to 20.3 ± 16.4; p<0.0001) at V2. Ninety-tree patients (18.6%) presented a clinically significant HRQoL impairment at V2. To be younger (OR=0.896; 95%CI, 0.829-0.968; p=0.006) and a woman (OR=4.181; 95%CI, 1.422-12.290; p=0.009), and a greater increase in BDI-II (Beck Depression Inventory – II) (OR=1.139; 95%CI, 1.053-1.231; p=0.001) and NMSS (Non-Motor Symptoms Scale) (OR=1.052; 95%CI, 1.028-1.076; p<0.0001) total scores from V0 to V2 were associated with clinically significant HRQoL impairment at 2 years follow-up, after adjustment to many covariates (Hosmer-Lemeshow test, p=0.665; R2=0.655). Specifically, an increase in ≥ 5 and ≥ 10 points of BDI-II and NMSS total score at V2 multiplied the probability of presenting a clinically significant QoL impairment by 5 (OR=5.453; 95%CI, 1.663-17.876; p=0.005) and 8 (OR=8.217; 95%CI, 2.975-22.696; p=0.002), respectively.
Conclusion: Age, gender, and mood and non-motor symptoms burden impairment were associated with clinically significant HRQoL impairment after 2 years follow-up in PD patients.
