AUA: Radical prostatectomy trends in the U.S.

Selezionata da Pietro Cazzola

ProstateAccording to a study presented at AUA, held in May in New Orleans, while the per capita utilization rate for radical prostatectomy (RP) in the U.S. remained stable from 1998 to 2011, the rapid expansion of minimally invasive RP (MI-RP) led to a considerable reduction in open RP procedures. 
Researchers from Mayo Clinic campuses in Scottsdale, Phoenix, and Jacksonville used data from the Nationwide Inpatient Sample on men 45 and older who underwent RP between 1998 and 2011. Their goal was to examine national trends in RP rates using a serial, cross-sectional analytic design. 
They estimated that 962,917 American men 45 and older underwent RP -- both open RP and MI-RP -- during the study period. The annual rate remained relatively stable, from 1425 RP per million in 1998-1999 to 1330 RP per million in 2010-2011 (P=0.90). However, the annual rate of open RP decreased from 1424 per million in 1998-1999 to 435 per million in 2010-2011 (P <0.001). At the same time, the annual rate of MI-RP increased from <1 per million in 1998-1999 to 895 per million in 2010-2011 (P <0.001). 
Since 2006, the estimated number of hospitals providing open RP has decreased by 18% (P<0.001), while the number of hospitals providing MI-RP has increased by 191% (P <0.001). The median open RP case load per hospital decreased by 7% (P <0.001), while the median case load for hospitals providing MI-RP has declined by 17% (P<.001).
