Patient-perceived involvement and satisfaction in Parkinson's disease: Effect on therapy decisions and quality of life

Patient-centered consultation styles are associated with higher patient satisfaction and improved health outcomes in diabetes and hypertension. In outpatient neurology, dissatisfaction with communication relates significantly to noncompliance. We undertook a single-center study in Parkinson's disease (PD) using standardized questionnaires to score patient-perceived involvement in therapy decisions (score 4 = low to 25 = high) and satisfaction with the consultation (score 1 = low to 7 = high). Correlation was tested against health outcomes of Unified Parkinson's Disease Rating Scale (UPDRS) Motor score, activities of daily living (UPDRS 2 and Schwab and England) Parkinson's disease quality of life (PDQ-39), Mini-Mentai State Examination (MMSE), and Geriatric Depression Scale (GDS). Of 117 patients enrolled, 107 (91%) fully completed the questionnaires. Mean patient- perceived involvement scored 14.4 (SD, 2.8). Mean satisfaction scored 5.3 (SD 0.7). Higher involvement was associated with increased satisfaction (r = 0.28; P = 0.003), particularly distress relief (r = 0.38; P < 0.0001). Communication scores correlated significantly with compliance intent (r = 0.6; P < 0.0001). There was no correlation between either involvement or satisfaction and UPDRS, Schwab and England, MMSE, or GDS. Quality of life was significantly associated with depression, UPDRS, duration of PD, compliance intent, and satisfaction. The significant positive association between compliance intent and quality of life in the more satisfied patient replicates findings in other disease areas. Due attention to these aspects in delivering care to the PD patient is appropriate. © 2005 Movement Disorder Society.
