Abstract Objectives Electronic health record (EHR) order preference lists and order sets potentially improve efficiency but have limited utility in complex primary care settings. We assessed adoption, impact on ordering efficiency, and clinician perceptions of a comprehensive set of nested order panels (xOrders) for adult primary care. Methods In Phase 1 (gradual implementation), 404 xOrders were released (November 29, 2020-September 25, 2021). Beginning of Phase 2 (rapid implementation), 630 xOrders were released with an additional 253 xOrders added (September 26, 2021-June 24, 2023). Three outcomes captured adoption: xOrders used per week; number of clinician users per week; and percent of xOrders of all orders. Impact of xOrders on times in orders per encounter per clinician was evaluated with mixed effects interrupted time series. t-Tests evaluated differences between low, moderate, and high utilizers. A survey captured clinicians’ perceptions in November 2022. Results xOrders were used 536 (SD, 245) times/week and by 57(15) clinicians/week in Phase 2. xOrders as a percent of all orders ranged from 0% to 31% across clinicians. Time spent in orders per encounter decreased by 14 ± 5 s (P =.01) from Phase 1 to 2 for high utilizers, decreased by 7(3) s (P=.05) for moderate utilizers, and increased by 1(3) s for low utilizers (P=.81); low and high utilizers were significantly different (P=.02). Most (77%) survey respondents agreed that xOrders improved ordering efficiency. Discussion and Conclusions Despite yielding time savings and positive clinician feedback, the xOrder intervention showed limited adoption and impact, suggesting the need for expanded content and increased adoption to realize larger efficiency gains.
