Anesthesia care was more common among patients undergoing cataract surgery compared with patients undergoing other low-risk procedures (89.8% vs range of &amp;amp;lt;1% to 70.2%). Neither the patient\u2019s age (adjusted odds ratio, 1.01; 95% CI, 1.00-1.02; <jats:italic>P<\/jats:italic>\u2009=\u2009.01) nor Charlson Comorbidity Index (CCI) score (CCI of \u22653: adjusted odds ratio, 1.06; 95% CI, 0.95-1.18; <jats:italic>P<\/jats:italic>\u2009=\u2009.28; reference, CCI score of 0-1) was strongly associated with anesthesia care for cataract surgery, but a model comprising a single variable identifying the ophthalmologist predicted anesthesia care with a C statistic of 0.96. Approximately 6.0% of ophthalmologists never used anesthesia care, 76.6% always used anesthesia care, and 17.4% used it for only a subset of patients. Fewer cataract surgery patients experienced systemic complications within 7 days (2833 [7.7%]), even when limited to patients of ophthalmologists who never used anesthesia care (108 [7.4%]), than patients undergoing other low-risk procedures (range, 13.2%-52.2%).<\/jats:p><\/jats:sec><jats:sec id=\"ab-ioi220059-10\"><jats:title>Conclusions and Relevance<\/jats:title><jats:p>The results of this cohort study suggest that systemic complications occurred less frequently after cataract surgery compared with other elective, low-risk, outpatient procedures during which anesthesia care was less commonly used. Anesthesia care was not associated with patient characteristics, such as older age or worse health status, but with the ophthalmologists\u2019 usual approach to cataract surgery sedation. The study findings suggest an opportunity to use anesthesia care more selectively in patients undergoing cataract surgery.<\/jats:p><\/jats:sec>","DOI":"10.1001\/jamainternmed.2022.4333","type":"journal-article","created":{"date-parts":[[2022,10,3]],"date-time":"2022-10-03T15:01:49Z","timestamp":1664809309000},"page":"1171","source":"Crossref","is-referenced-by-count":25,"title":["Anesthesia Care for Cataract Surgery in Medicare Beneficiaries"],"prefix":"10.1001","volume":"182","author":[{"given":"Dhivya","family":"Perumal","sequence":"first","affiliation":[{"name":"Department of Anesthesiology and Perioperative Care, University of California, San Francisco"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.
