OBJECTIVE: To examine the association of laser technology adoption in a market with surgery rates for benign prostatic hyperplasia. METHODS: Using the Florida files from the State Ambulatory and Inpatient Surgery Databases (2001-2009), we identified all patients who underwent transurethral surgery for benign prostatic hyperplasia. We calculated rates of benign prostatic hyperplasia surgery for all markets within the state (defined by Hospital Service Area) over time. Markets were split into 3 categories: (1) Always offering, (2) never offering, or (3) initially not offering but adopting laser prostatectomy after 2001. We used multivariable regression models to estimate surgery rates adjusted for other market characteristics. Interaction terms were included in the models to examine differences in time trends between market categories. RESULTS: After adjusting for market characteristics, time trends differed by market category (P < .001). Surgery rates decreased from 318 to 248 procedures per 100,000 men in markets always offering laser prostatectomy (P < .001). Markets never offering laser surgery had much lower rates that remained stable (180-187 procedures per 100,000 men, P = .805). In markets adopting laser technology, rates increased from 268 to 296 procedures per 100,000 men after adoption (P = .044), such that 4 years after adoption these markets had the highest rates among the 3 categories. CONCLUSION: Adoption of laser technology is associated with rising rates of surgical intervention for benign prostatic hyperplasia. This trend appears to be induced by the introduction of laser surgery.
