| Abstract | BACKGROUND: Two previous retrospective database analyses compared early combination therapy with an -blocker (AB) and 5- reductase inhibitor (5-ARI) to delayed combination therapy and found that patients receiving the delayed combination therapy were more likely to have clinical progression, acute urinary retention (AUR), and surgery. Although these studies indicate the clinical benefits of early treatment, both studies failed to take into account important baseline clinical measures, such as prostate-specific antigen (PSA) values. OBJECTIVE: This study was designed to compare clinical and cost differences in men with benign prostatic hyperplasia (BPH) who initiated early versus delayed combination therapy with a 5-ARI + an AB, factoring in baseline PSA values. METHODS: This retrospective claims data analysis assessed data from >14 million US men with linked medical data, pharmacy data, laboratory results, and enrollment information from January 1, 2000, to December 31, 2009. Men aged 50 or older and treated for BPH with a 5-ARI + an AB were identified. Patients were required to be eligible for services at least 6 months before and 12 months after the index medication date. Patients were assigned to 1 of 2 treatment groups based on therapy (early or delayed) and 3 cohorts based on availability of PSA laboratory values (patients with a PSA value, patients with a PSA value >1.5 and <10, and all patients). Using a logistic model, the likelihood of clinical progression (defined as the occurrence of AUR or prostate surgery) during the 12 months after the date of first prescription fill was compared between BPH patients receiving early versus delayed combination therapy. BPH-related medical costs (excluding pharmacy costs) were assessed using generalized linear models. RESULTS: Among the 13,551 patients identified for study inclusion, the highest risks for clinical progression, AUR, and prostate-related surgery were consistently demonstrated in patients with a PSA >1.5 and <10. Across all 3 cohorts, the delayed combination-treatment group was more likely to have clinical progression, AUR, and prostate-related surgeries versus the early combination-treatment group. The incremental difference in BPH-related costs between the delayed and early combination-treatment groups was \$190 per patient overall; the greatest incremental difference (\$397) was observed in patients with PSA >1.5 and <10. CONCLUSIONS: The results suggest that early initiation of combination therapy with 5-ARI + an AB, compared with delayed initiation, can reduce the risks for clinical progression, AUR, and prostate-related surgeries, as well as BPH-related medical costs, in patients with BPH. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
