Purpose: To determine whether routine preoperative assessment impacts the rate of medical and surgical complications in patients undergoing ophthalmic surgery.
Study Design: Systematic review.
Methods: A search of Ovid MEDLINE, EMBASE, and Cochrane CENTRAL was conducted to identify relevant articles published between 2000 and March 2020. Original articles investigating preoperative assessments performed by any healthcare professional prior to ophthalmic surgery were included. For each study, the rates of perioperative ocular and systemic complications were reported using descriptive statistics.
Results: A total of 10 805 articles were identified, of which nine studies were selected for inclusion. Overall, four studies were randomized controlled trials (RCTs) and five were observational studies. Eight studies reported on cataract surgery and one on vitreoretinal surgery. In two studies, the preoperative assessment consisted of a patient-administered questionnaire, while the remaining studies involved a combination of history, physical examination, laboratory testing, electrocardiogram, chest x-ray, and other investigations. Preoperative testing in routine settings did not decrease the rates of adverse events or the risk of perioperative ocular and systemic complications in any study. Two studies suggested that patients with pre-existing hypertension, congestive heart failure, coronary artery disease, arrhythmia, diabetes, anemia, pulmonary disease, or renal disease were at a higher risk for adverse events perioperatively. Patients with pre-existing comorbidities who underwent preoperative testing had a lower risk of complications in one study, while no difference was found in another. Risk of bias assessment generally revealed a lack of masking in RCTs and confounding of effect in observational studies.
Conclusions: Across 48 869 eyes, routine preoperative medical testing prior to ophthalmic surgery did not reduce the rate of perioperative ocular or systemic surgical complications. Patients with certain pre-existing comorbidities may be at an increased risk of developing adverse events, and the role of preoperative testing is not well delineated in this population. Further studies are required to determine whether these conclusions are true across diverse subspecialties and to determine the comparative safety, effectiveness, and implementation of alternative preoperative assessment tools.
