National trends in surgical therapy for benign prostatic hyperplasia in the United States (2000-2008)

Abstract

Objective: To report an update of the change in usage trends for different surgical treatments of benign prostatic hyperplasia (BPH) among the United States Medicare population data from 2000-2008. The rate of usage of thermotherapy and laser therapy in the surgical treatment of BPH has been changing over the past decade in conjunction with a steady decrease of transurethral resection of the prostate (TURP). Methods: Using the 100% Medicare carrier file for the years 2000-2008, we calculated counts and population-adjusted rates of BPH surgery. Rates of TURP, thermotherapy, and laser-using modalities were calculated and compared in relation to age, race, clinical setting, and reimbursement. Results: After years of a steady rise, the total rate of all BPH procedures peaked in 2005 at 1078/100,000 and then declined by 15.4% to 912/100,000 in 2008. TURP rates continued to decline from 670 in 2000 to 351/100,000 in 2008. Rates of microwave thermoablation peaked in 2006 at 266/100,000 and then declined 26% in 2008. Laser vaporization almost completely replaced laser coagulation and in 2008 was the most commonly performed procedure second to TURP, with the majority performed as outpatient procedures (70%) and an increasing percentage in the office (12%). Men between ages 70 and 75 had the highest rate of procedures. Reimbursement rates correlate using some but not all procedures. Racial disparities reported previously appear to have resolved. Conclusion: Surgical treatment of BPH continues to change rapidly. TURP continues to decline and laser vaporization is the fastest growing modality. There is a big shift toward outpatient/office procedures. Reimbursement rates do not appear to have a consistent effect on usage. © 2012 Elsevier Inc.
