Allied health care in Parkinson's disease: referral, consultation, and professional expertise.

There is evidence for the efficacy of allied health care in Parkinson's disease (PD). However, barriers exist that hamper implementation of evidence into daily practice. We conducted a survey to investigate: (1) to what extent PD patients currently utilize allied health care for relevant problems in the core areas of allied health care and (2) the level of PD-specific expertise among allied health professionals. Questionnaires were sent to 260 patients and 297 allied health professionals. Referral rates were 63% for physical therapy, 9% for occupational therapy, and 14% for speech therapy. PD patients with problems that can potentially be alleviated by input from allied health professionals are often not being referred. Furthermore, most patients were treated by allied health professionals who lacked PD-specific expertise. Current referral to and delivery of allied health care in PD are suboptimal. Evidence-based guidelines for allied health care in PD and active implementation of these guidelines are needed.
