Objective:
Surgical care is increasingly shifting to freestanding ambulatory surgical centers (ASCs). The extent to which otolaryngologists use ASCs has implications for patient safety and health care spending. This study characterizes trends in utilization and resultant financial implications for common otolaryngologic procedures performed at ASC and hospital outpatient departments (HOPDs).
Study Design:
Retrospective cross-sectional analysis.
Setting:
ASCs, HOPDs.
Subjects And Methods:
Subjects included Medicare beneficiaries undergoing outpatient otolaryngologic procedures between 2010 and 2017. Procedures included the 20 highest-volume procedures performed by otolaryngologists at ASCs in 2017. Main outcomes included absolute and relative percentage difference in the proportion of procedures furnished at ASCs and HOPDs and estimated Medicare cost savings resulting from increased ASC utilization between 2011 and 2017.
Results:
The proportion of outpatient otolaryngologic procedures performed at ASCs increased by 1.8% (relative difference: 10.0%; mean annual relative increase: 1.60%), and the proportion located at HOPDs decreased by 6.0% (relative difference: -11.8%; mean annual relative decrease: -1.6%) between 2010 and 2017. Rhinoplasty accounted for the largest absolute increase in ASC utilization over the study period (absolute [relative] 8.9% [33.5%]). Increased ASC utilization resulted in an estimated $7.1 million in cost savings to Medicare between 2011 and 2017.
Conclusion:
Otolaryngologists shifted outpatient surgical care from HOPDs to ASCs between 2010 and 2017, with resultant reductions in Medicare expenditures. Further research is necessary to examine the impact of this shift on patient safety.
