ABSTRACT

Purpose: Achieving competency in cataract surgery is an essential component of ophthalmology residency training. Video-based analysis of surgery can change training through its objective, reliable, and timely assessment of resident performance. Methods: Using the Image Labeler application in MATLAB, the capsulorrhexis step of 208 surgical videos, recorded at the University of Michigan, was annotated for subjective and objective analysis. Two expert surgeons graded the creation of the capsulorrhexis based on the International Council of Ophthalmology's Ophthalmology Surgical Competency Assessment Rubric:Phacoemulsification (ICO-OSCAR:phaco) rating scale and a custom rubric (eccentricity, roundness, size, centration) that focuses on the objective aspects of this step. The annotated rhexis frames were run through an automated analysis to obtain objective scores for these components. The subjective scores were compared using both intra and inter-rater analyses to assess the consistency of a human-graded scale. The subjective and objective scores were compared using intraclass correlation methods to determine relative agreement. Results: All rhexes were graded as 4/5 or 5/5 by both raters for both items 4 and 5 of the ICO-OSCAR:phaco rating scale. Only roundness scores were statistically different between the subjective graders (mean difference = -0.149, p-value = 0.0023). Subjective scores were highly correlated for all components (>0.6). Correlations between objective and subjective scores were low (0.09 to 0.39). Conclusion: Video-based analysis of cataract surgery presents significant opportunities, including the ability to asynchronously evaluate performance and provide longitudinal assessment. Subjective scoring between two raters was moderately correlated for each component.

ABSTRACT

PURPOSE: The purpose of this study was to characterize rates of opioid prescription for different ulcerative keratitis types. METHODS: This cohort study included patients diagnosed with ulcerative keratitis according to the University of Michigan electronic health record data between September 1, 2014 and December 22, 2020. Ulcerative keratitis was categorized by etiologic type (bacterial, fungal, viral, acanthamoeba, inflammatory, polymicrobial, or unspecified) using rule-based data classification that accounted for billing diagnosis code, antimicrobial or antiinflammatory medications prescribed, laboratory results, and manual chart review. Opioid prescriptions were converted to morphine milligram equivalent and summed over 90 days from diagnosis. Opioid prescription rate and amount were compared between ulcerative keratitis types. RESULTS: Of 3322 patients with ulcerative keratitis, 173 (5.2%) were prescribed at least 1 opioid for pain management within 90 days of diagnosis. More patients with acanthamoeba (32.4%), fungal (21.1%), and polymicrobial (25.0%) keratitis were treated with opioids compared with bacterial (6.7%), unspecified (2.9%), or viral (1.8%) keratitis (all Bonferroni adjusted P < 0.05). For the 173 patients who were prescribed opioids, a total of 353 prescriptions were given within 90 days of diagnosis, with half given within the first week after diagnosis. The quantity of opioid prescribed within 90 days from diagnosis was not significantly different between ulcerative keratitis types (P = 0.6559). Morphine milligram equivalent units prescribed ranged from 97.5 for acanthamoeba keratitis to 112.5 for fungal keratitis. CONCLUSIONS: The type of ulcerative keratitis may influence the opioid prescription rate. Providers can better serve patients needing opioids for pain management through improved characterization of pain and development of more tailored pain management regimens.
