From: From prescriptions to drug use periods - things to notice
An individual’s purchase history for about six years, which describes the purchase of 20 different drugs. Note the long hospital stays between days 679–719, 1506–1574 and 2113–2250 (marked with grey bars). After day 2250, this person has not collected any drugs and resides in nursing home, so no information on drug use is available in the prescription register.
