Patient and physician perceptions of disease management in Parkinson's disease: results from a US-based multicenter...

Background: Clinical care for patients with Parkinson's disease (PD) is complex, and disconnect may exist between patient and physician perceptions of treatment, disease awareness, and impact on quality of life (QoL). Relatively few studies have analyzed patient and physician perspectives of disease management concurrently, and even fewer have compared responses between corresponding patients and their physicians. This study aimed to characterize these aspects and identify opportunities to improve alignment. Methods: This cross-sectional study used an online survey and chart review. Participating physicians completed a profiling survey, followed by patient record forms (PRFs) for their next five patients with PD. Patients completed paper questionnaires. PRFs were matched with patient questionnaires, and patient and physician responses compared. Results: Of 107 participating physicians, 70 completed 350 PRFs. Patients completed 71 questionnaires; 66 were matched to PRFs. From a physician perspective, there was alignment between the motor symptoms that were most bothersome for patients and those that were most discussed (physicians felt tremor was most bothersome for most patients [71%]; 77% of physicians included tremor among top three most discussed), but disconnect between the most bothersome and most discussed nonmotor symptoms (physicians felt fatigue was most bothersome for most patients [35%]; cognitive impairment was the most discussed nonmotor symptom, with 52% of physicians including it in top three most discussed). Patients and physicians reported moderate satisfaction with current PD medication. Patients considered form of delivery more important than did physicians. Physicians showed a strong level of awareness of PD's impact on patient QoL, although validated QoL instruments were not widely used. Physicians were more confident than patients about patients' awareness of support resources for patients with PD. Conclusion: Nonmotor symptoms, form of medication delivery, and awareness of support services are areas where PD physician and patient alignment could be increased to improve outcomes.
