BACKGROUND: Cataract surgery is usually performed with topical anesthesia and sedation, which may be provided through a number of different care models with or without involvement of a physician anesthesiologist. We sought to describe anesthesiology care for cataract surgery in Ontario, Canada, and examine the association between the model of anesthesiology care and health service and perioperative outcomes after cataract surgery.
METHODS: We conducted a population-based study of patients who underwent cataract surgery in Ontario using linked health administrative data between 2012 and 2021. The primary outcome was a composite of death, acute hospital admission, or emergency department visit up to 7 days postoperatively. We also collected data on health system costs and operative complications (from physician billing codes). We used multilevel, multivariable regression to estimate adjusted associations between anesthesiology care - fee-for-service anesthesiology care (FFS), care from an anesthesiology care team (ACT), or no physician anesthesiologist care - and outcomes.
RESULTS: Of 1 271 251 patients who underwent cataract surgery, 670 754 (52.8%) received FFS care, 256 760 (20.2%) received ACT care, and 343 737 (27.0%) had no physician anesthesiologist care. Adjusted analyses estimated slightly lower odds of the primary composite outcome for patients who received FFS care (n = 8682, 1.3%; adjusted odds ratio [OR] 0.93, 95% confidence interval [CI] 0.88 to 0.99) or ACT care (n = 3034, 1.2%; adjusted OR 0.83, 95% CI 0.76 to 0.89) compared with those with no physician anesthesiologist care (n = 5056, 1.5%). Odds of operative complications were lower and overall costs were higher with any type of physician-provided anesthesiology care. Primary results differed by whether care was provided in a teaching or nonteaching hospital.
INTERPRETATION: Care provided or overseen by a physician anesthesiologist was associated with significantly lower odds of an emergency department visit, hospital admission, or death; however, effect sizes were small and of limited clinical importance, and costs were higher. Given these findings, the use of physician anesthesiology care for routine cataract surgery should be reconsidered.
