Despite the increasing prevalence of Parkinson’s disease (PD) in Australia, there is limited data about experiences of people with Parkinson’s (PwP) during the diagnostic process and post-diagnosis. This study surveyed experiences of PwP from initial symptoms, throughout diagnostic consultation, and support provided following diagnosis through a national web-based survey. In total, 385 participants accessed the questionnaire, with 335 full completions. Responses from participants living in capital and regional city centers showed patient satisfaction with clinical care during diagnostic consultation at approximately 40%. Satisfaction in clinical care was less in rural areas (26%). Moreover, the majority of participants (68%), irrespective of geographical location, felt they were not adequately involved in discussions about treatment and care planning. Overall, 77% of participants reported dissatisfaction with the level of support of their clinical care teams. Furthermore, respondents reported that clinician referral to allied-health providers were low, with only 22% of participants accessing physiotherapy and 17% referred to mental health services. From respondents who provided additional feedback how PwP could be better supported following diagnosis, the top two responses were greater access and engagement with Parkinson’s disease Clinical Nurse Specialists, and the development of PD-specific apps to increase access to educational resources and support. Findings from this study highlight the necessity for the development of Australian guidelines for PD clinical management, greater resourcing for PD clinicians including development of educational programs, and creation of an Australian-centric educational resources. Addressing these gaps may improve perceived quality of care and overall patient satisfaction for PwP in Australia.
