Abstract/OtherAbstract:
BACKGROUND AND OBJECTIVE: Recent clinical trials indicate that combining an alpha blocker for rapid symptom improvement and a 5-alpha reductase inhibitor (5-ARI) to reduce the risk of clinical progression of benign prostatic hyperplasia (BPH) may be an optimal approach to management; however, few studies have evaluated the effect of combination therapy on clinical progression in a real-world setting. The purpose of our study was to assess the clinical and economic impact of early versus delayed 5-ARI therapy in patients treated with an alpha blocker for BPH.
MATERIALS AND METHODS: A retrospective database analysis included men 50 years of age and older who were treated for BPH between 2003 and 2007. Clinical outcomes were evaluated for patients using 5-ARIs early (within 30 days of starting an alpha blocker) compared with those using delayed 5-ARI therapy (between 30 and 180 days after starting an alpha blocker). We assessed the likelihood of clinical progression (defined as the occurrence of acute urinary retention or prostate surgery) for each group over a one-year period following the start of alpha-blocker therapy.
DATA SOURCE: The MarketScan Database, which was used to identify patients, contains medical and pharmacy claims data obtained directly from Medicare and commercial health plans and employers, representing 18 to 20 million lives annually.
RESULTS: Of 8,617 men included in the analysis, 64.5% began 5-ARI therapy within 30 days of alpha-blocker therapy (the early cohort). These patients were less likely than those receiving delayed 5-ARI treatment to have clinical progression (12.8% vs. 17.4% respectively; P < 0.0001), acute urinary retention (10.2% vs. 13.8%, P < 0.0001), and prostate surgery (5% vs. 7%, P = 0.0002). The early group also incurred lower BPH-related medical costs ($572 vs. $730, P < 0.0001). Even though BPH-related pharmacy costs were significantly higher ($1,137 vs. $1,263, P = 0.0313), their total BPH-related costs were lower ($1,834 vs. $1,867, P = 0.0068).
CONCLUSION: These results suggest that early 5-ARI therapy for men with symptomatic BPH who receive an alpha blocker may significantly reduce the risk of clinical progression (i.e., acute urinary retention or prostate surgery) over the next 12 months as well as lower BPH-related medical costs and BPH-related total costs.
