Assessment of Parkinson's disease medication-related motor complications quality measure

Quality of Patient Care = Patients Who Meet Criterion / (Eligible Population - Exclusions)

Measure purpose: Ensure patients with Parkinson's disease (PD) on a dopaminergic medication are assessed for dopaminergic medication-related motor complications regularly. 

The numerator: Patients who were assessed for dopaminergic medication-related motor complications once during the measurement period

is divided by

The denominator: All patients with a diagnosis of PD on a dopaminergic medication


Exclusions are removed from the denominator:

  • On date of encounter, patient is not able to participate in assessment, including non-verbal patients, delirious, severely aphasic, severely developmentally delayed, severe visual or hearing impairment and for those patients, no knowledgeable informant available.

Key phrases

Examples of key phrases you could use to meet the measure include:

  • Assessed wearing off
  • Patient reports dyskinesia
  • Patient reports no dystonia
  • On-off phenomena assessed

Measure calculation example

Dr. Costa has 500 patient visits between January 1 and December for patients diagnosed with PD who were prescribed a dopaminergic medication. This is the denominator. 

During 27 visits, patients were unable to provide information and did not have an informant available to provide information. These visits meet the exclusion criteria and are removed from the denominator.

Of the now 473 visits that still qualify for this measure, 218 had documentation that the patients were queried about dopaminergic medication-related motor complications (i.e., wearing off, dyskinesia, dystonia, on-off phenomena, and amount of off time).  This is the numerator. 

Quality of patient care = 218/(500-27). Dr. Costa has a score of 46.1% for this measure.
