Benign Prostatic Hyperplasia Clinical Trial
Official title:
Clinical Progression and Costs in Benign Prostatic Hyperplasia Patients Treated With Early Versus Delayed Combination Therapy
In patients with benign prostatic hyperplasia (BPH), combination therapy with an
alpha-blocker (AB) and a 5 alpha-reductase inhibitor (5ARI) has been shown to reduce the
progression of acute urinary retention (AUR) and the incidence of prostate surgery, and also
provides symptom relief.
The objective of this study is to compare the likelihood of clinical progression (defined as
AUR and/or prostate-related surgery) and costs in BPH patients who were treated with delayed
combination therapy to BPH patients who were treated with early combination therapy using
data from a United States (US) healthcare claims database. The hypothesis of this study is
that patients who are prescribed combination therapy early in their BPH treatment will
experience better clinical outcomes and lower healthcare costs compared with patients
treated with delayed combination therapy. The null hypothesis is that no difference will be
observed in outcomes or direct medical costs for patients treated with early combination
therapy and patients treated with delayed combination therapy.
The US healthcare claims database includes data from patients with Medicare Advantage as
well as private health plan coverage including the Impact health plan. About 14 million
people were covered by this set of health plans in 2007 and were geographically diverse
across the US. Data from 2000 through 2009 were utilized.
The study is a retrospective cohort analysis.
