Indicators for a complete list of patients’ health problems:

1. Average number of active episodes of care per patient

2. Number of episodes that have a “special attention label” as percentage of the episodes that should have this label

Indicators for completeness of diagnosis codes:

3. Percentage of episodes that have a “meaningful” ICPC code

4. Completeness of ICPC coding for several diseases based on drug treatment. This was done for:

4a. Diabetes: number of patients who have an episode of diabetes (T90) recorded, as percentage of patients taking blood glucose–lowering medication (A10B)

4b. Asthma/COPD: number of patients who have an episode of asthma or COPD (ICPC R95/R96) recorded, as percentage of patients taking sympathomimetics (ATC: R03A), glucocorticoids (R03BA), or parasympathicolytics (R03BB)

4c. Cardiovascular disease: number of patients who have an episode of hypertension (K86/K87), angina pectoris (K74), heart failure (K77), atrial fibrillation (K78), or other chronic ischemic heart disease (K76) recorded, as percentage of patients taking diuretics (C03), beta-blockers (C07), calcium antagonists (C08), or agents targeting the renin angiotensin system (C09)

4d. Depression: number of patients who have an episode of anxiety disorder (ICPC P74), depressed feelings (P03), or depression (P76) recorded, as percentage of patients taking antidepressants (ATC N06A)

4e. Parkinson’s disease: number of patients who have an episode of Parkinson’s disease (N87) recorded, as percentage of patients taking dopa and its derivatives (N04BA)

4f. Epilepsy: number of patients who have an episode of epilepsy (N88) recorded, as a percentage of patients taking anticonvulsants (N03)

4g. Thyroid disorder: number of patients who have an episode of thyroid disorder (ICPC T85/T86) recorded, as a percentage of patients taking thyroid mimetics (H03A) or thyroid statics (H03B)

Indicator for structuring information into episode of care:

5. Percentage of patient encounters recorded as part of an episode of care

Indicators for an appropriate medication list:

6. Percentage of drugs not prescribed in the last 6 months, but still labeled as “current medication”

8. Percentage of drugs linked to an episode of care

9. Percentage of drugs linked to an episode with a meaningful ICPC code

Indicators for medication safety:

10. Percentage of patients for whom a medication allergy or intolerance is recorded

11. Percentage of patients for whom a contraindication is recorded
