PIMs = potentially inappropriate medications.
*
In the case of patients who prescribed potentially inappropriate medicines for the elderly patients have 2 or more claims for the main diagnosis or subdiagnosis in the same year, then counts “Yes” (based on the health insurance claims). If there are no more than 2 claims due to inpatient or outpatient treatment due to chronic disease, it counts as 0.
** means that duplicated cases were removed.
