Introduction and hypothesis
The epidemiologic description of pelvic organ prolapse (POP) and stress urinary incontinence (SUI) procedures is documented in several large studies using national database cohorts. These studies, however, may underestimate the number of procedures performed because they only capture procedures performed in either the inpatient or outpatient settings alone. We present a complete annual description of all inpatient and outpatient surgeries for POP and SUI in California.
Methods
We reviewed a record of all inpatient and outpatient POP and SUI surgeries performed in California in 2008 using data from the Office of Statewide Health Planning (OSHPD).
Results
In 2008, 20,004 and 20,330 women in California underwent POP and SUI procedures, respectively. Of these, 3,134 (15.6 %) and 9,016 (44.3 %) were performed in an outpatient setting. The age-adjusted rates of POP and SUI were 1.20 and 1.20 per 1,000 US females, respectively. This correlates to 186,000 POP and 186,000 SUI procedures per year nationally. Vaginal apical suspensions were more common in those undergoing surgery as an inpatient (45.1 vs 19.4 %). The use of mesh to augment prolapse repairs was similar (22.3 % inpatient vs 19.3 % outpatient). SUI procedures performed in the outpatient setting were more likely to be performed as stand-alone procedures (82.9 vs 18.8 %, respectively).
Conclusions
In California, 16 % of POP and 44 % of SUI procedures were performed in an outpatient surgical setting in 2008. Epidemiologic studies of POP and SUI should account for the fact that a substantial number of repairs are performed in the outpatient setting in order to achieve accuracy.
