Background and objective: To evaluate the utilization rates of ambulatory surgery centers (ASCs) in the state of Florida for vitreoretinal, cataract, and glaucoma surgical procedures over a 13-year period from 1999 through 2011.
Patients and methods: Retrospective analysis utilizing the State Ambulatory Surgery Databases (SASD) for Florida from 1999 through 2011. ICD-9 codes for vitreoretinal, cataract, and glaucoma procedures were queried. Joinpoint regression was used to calculate average annual percent change (APC) in ASC utilization by these procedures over the 13-year study period and also separately for the years 2007 to 2011.
Results: From 1999 through 2011, APC in ambulatory surgery center utilization was +26.4% (P = .0039) for vitreoretinal, +21.3% (P = .012) for cataract, and +20.9% (P = .0063) for glaucoma surgery. The APC from 2007 through 2011 was -1.2% for vitreoretinal (P = .47), -9.2% for cataract (P = .0039), and -17.3% for glaucoma surgery (P = .008).
Conclusion: A significant overall increase in ASC utilization by vitreoretinal, cataract, and glaucoma surgeons over the study period was seen; however, the most recent 5-year data show that these trends may have begun to reverse.
