Primary Outcome Measures:
  • Number of Participants by Treatment Cohort With and Without a Benign Prostatic Hypertrophy (BPH) Diagnosis [ Time Frame: 4 years ]
    The number of participants treated with alpha-blocker (AB) and 5a lpha reductase inhibitor (5ARI) as monotherapy or in combination reported by the presence or absence of a diagnosis code for BPH (International Classification of Disease, Ninth Revision, Clinical Modification codes: 222.2 and 600.xx). Early combination therapy was defined as the addition of 5ARI to existing AB therapy within 30 days of the initial AB pharmacy claim. Delayed combination therapy was defined as the addition of 5ARI to AB therapy after 30 day but within one year of the initial AB pharmacy claim.
