|Initial Patient Population:||
Patients 18 years of age and older with a diagnosis of major depression in the 270 days (9 months) prior to the measurement period or the first 90 days (3 months) of the measurement period, who were treated with antidepressant medication, and with a visit during the measurement period

To identify new treatment episodes for major depression, there must be a 90-day negative medication history (a period during which the patient was not taking antidepressant medication) prior to the first dispensing event associated with the Index Episode Start Date (Index Prescription Start Date).
CUMULATIVE MEDICATION DURATION is an individual’s total number of medication days over a specific period; the period counts multiple prescriptions with gaps in between, but does not count the gaps during which a medication was not dispensed.
To determine the cumulative medication duration, determine first the number of the Medication Days for each prescription in the period: the number of doses divided by the dose frequency per day. Then add the Medication Days for each prescription without counting any days between the prescriptions.
For example, there is an original prescription for 30 days with 2 refills for thirty days each. After a gap of 3 months, the medication was prescribed again for 60 days with 1 refill for 60 days. The cumulative medication duration is (30 x 3) + (60 x 2) = 210 days over the 10 month period.
