Comparing No-Show Rates of Neurology Outpatients with and without Parkinson's Disease: A Real-World Assessment of the Parkinsonian Personality Profile.

BACKGROUND
Parkinson's disease (PD) has been hypothesized to be associated with certain personality traits, including conscientiousness and punctuality. However, research aimed at quantifying these traits is largely derived from questionnaire-based personality inventories rather than real-world observations.


OBJECTIVE
To explore the presence of a parkinsonian personality profile by assessing the no-show rate of patients with PD versus other neurological disorders.


METHODS
We extracted data from our electronic health record for all neurology appointments over a 78-month interval. Additionally, we obtained primary care appointment data for the same patients over the same timeframe. For each appointment we collected appointment date/time, check-in time, provider, age, sex, insurance type, days between appointment date and scheduling, diagnosis code, and no-show status.


RESULTS
19,433 unique patients (400 with PD) accounting for a total of 252,347 outpatient appointments were included in our analysis. The overall no-show rate for PD patients was 3% versus 7.4% for patients with other neurologic disorders (OND). No show rates for PD patients were lower than those with OND for both neurology appointments (2.7% versus 13.6%) and for primary care visits (3.1% versus 5.9%).


CONCLUSIONS
Patients with PD have lower no-show rates than patients with OND. Additionally, the no-show rate for patients with PD did not differ between their neurology and primary care appointments, confirming that patient's personality rather than provider traits account for this difference, and supporting the presence of a parkinsonian personality.
