Abstract
IMPORTANCE: Determining the association of surgical setting and implementation of a new electronic health record (EHR) system with ophthalmic operative times is important for surgical planning and resource allocation. OBJECTIVE: To assess the associations of surgical setting and EHR system replacement with operative times for ophthalmic surgery. DESIGN, SETTING, AND PARTICIPANTS: This case series included ophthalmic surgeries from July 2015 to November 2016 in 2 ambulatory surgical centers and 1 hospital outpatient department in a single academic eye institute. Operative times from consecutive surgical cases performed by board-certified ophthalmologists were extracted from 2 EHR systems. Those performed after replacement EHR system implementation were divided into three 50-day time categories (immediate posttransition, intermediate posttransition, and late posttransition periods). Multivariable regression analyses assessed the associations of surgical setting (hospital outpatient department vs ambulatory surgical center) with total operating room times for comparable surgeons performing cataract surgery and deployment of a new EHR system in the OR on several operative time measures. Data were evaluated from November 2016 to March 2018. MAIN OUTCOMES AND MEASURES: Room duration, procedure duration, turnaround time, and total OR time. RESULTS: A total of 11 064 cases performed by 76 surgeons were included in this analysis. The mean total OR time was 2.9 (95% CI, 0.5-5.4; P = .02) minutes longer in the immediate posttransition period and 1.2 (95% CI, 0.1-2.2; P = .04) minutes longer in the intermediate posttransition period relative to surgeries performed before EHR system replacement. No difference in the total OR time was found between the late posttransition and pretransition periods. Relative to ambulatory surgical centers, the mean total OR time was 15.9 (95% CI, 14.7-17.0) minutes longer, and the mean turnaround time was 5.1 (95% CI, 4.3-6.0) minutes longer at the hospital outpatient department for comparable surgeons performing cataract surgery (P < .001 for both). CONCLUSIONS AND RELEVANCE: The mean total OR time per case lengthened after the replacement of an EHR system in the OR, but this increase was small (shorter than 3 minutes) and limited to surgeries performed during the first 100 days after the EHR system transition. Modeling to assess surgical setting demonstrated all operative time measures were longer for cataract cases performed at the hospital outpatient department relative to those at ambulatory surgical centers. These data have implications for the fiscal and logistical management of ophthalmic surgery.
