Intervention components in the self-management of Parkinson's: a mixed-methods synthesis of qualitative and quantitative evidence

Self-management interventions consist of multiple components to support people in the management of medical, emotional, and behavioural aspects of their condition, and aim to improve quality of life, function, and other outcomes. A systematic review of self-management interventions in Parkinson's showed no conclusive evidence for effectiveness of specific self-management approaches in Parkinson's to date but identified several potentially useful components. To identify the key required components for self-management in people with Parkinson's by synthesising evidence from a body of primary qualitative evidence and systematic reviews, and to explore which of these key components should be incorporated into trials of self-management in Parkinson's. A mixed-methods synthesis was conducted. We combined data from two primary qualitative studies and a systematic review of qualitative studies that focused on self-management in Parkinson's to identify key intervention components. These were then mapped onto the results of a systematic review of Randomised Controlled Trials (RCTs) using matrices. First, data were extracted from the qualitative studies with people with Parkinson's and healthcare professionals on the key self-management components in this population. Second, a matrix table was created to map the identified Parkinson's specific self-management components against potential effectiveness from published RCTs of self-management interventions. Synthesis of qualitative data identified 15 potential self-management components. These 15 components included components needed to start self-managing (e.g., information, skill acquirement) and components needed to maintain self-managing (e.g., self-motoring, increasing motivation). From 18 RCTs, interventions varied in how many components were included (range 1-10). Trials reporting significant beneficial effects of their intervention included a higher number of components (4 or more self-management components) than trials without significant findings (1-3 self-management components). Fifteen key self-management components were identified that should be incorporated into interventions or programs of self-management in Parkinson's. No current trial has incorporated all aspects, but a higher number of these key components appears to make trials of self-management interventions more likely to be successful.
