The diseases most often related to potentially preventable drug-related revisits were heart failure (n=24, 28%), chronic obstructive pulmonary disease (COPD; n=13, 15%), atrial fibrillation (n=7, 8.2%) and gastrointestinal bleeding or ulcer (n=7, 8.2%; Table 2).
Five main causes of potentially preventable drug-related revisits were identified (Table 3): inadequate treatment (n=23, 27%), insufficient or no follow-up (n=22, 26%), non-compliance (n=21, 25%), lack of investigation or diagnostics (n=10, 12%) and inappropriate treatment (n=9, 11%). The origin of the cause of these visits within healthcare was more often hospital care (n=49, 58%) than primary care (n=27, 32%). In nine (11%) cases, the origin of the cause was either unclear or the visit seemed to be caused by the patient.
