Factors that predict a change in quality of life among Parkinson's disease patients participating in a patient education program

BackgroundPatient education is essential in Parkinson's disease (PD). However, it is not known which aspects of patient education are associated with an improvement in quality of life (QoL).ObjectiveTo identify factors that predicted an improvement in QoL in PD patients that participate in an education program.MethodsEduPark is a community-hospital patient education program. PD Patients that had participated in the program between September 2013 and March 2017 were retrospectively included. QoL was prospectively evaluated (using the PDQ-8 questionnaire) before and after the patient's participation. We used mixed linear models (adjusted for the initial value of the PDQ-8) to determine socio-demographic and clinical variables that predicted the change in the PDQ-8 score.ResultsA total of 181 patients were included (mean ± standard deviation age: 62.9 ± 8.2 years; disease duration: 9.1 ± 5.3 years). 76.7% of the 103 patients having undergone a cognitive evaluation did not display cognitive impairment. We did not identify any factors that predicted the program's impact on the patient's QoL. Participation in the program was associated with a significant decrease (improvement) in the PDQ-8 score (39.4 ± 17.81 before and 35.6 ± 15.9 afterwards, P < 0.001).ConclusionWe did not identify any factors that were predictive of the patient education program's impact on QoL in patients with PD. Participation in the program was associated with a significant improvement in QoL. Our results suggest that Patient Education Programs should be more widely prescribed and developed in the management of PD.
