Continuous User Experience Monitoring of a Patient-completed Preoperative Assessment System in The United Kingdom: Cross-sectional Study (Preprint)

Background: Anesthetic preoperative assessment (POA) is now a common part of the surgical care pathway, and guidelines support its routine use. MyPreOp (Ultramed Ltd) web-based POA system that enables remote assessments. Usability key factor in success digital health solutions. Objective: This study aims to assess usability through patient feedback, investigate amount time it took for patients complete questionnaire factors influenced completion time, explore effect on times implementing validated eHealth scale, as compared using simple but unvalidated evaluation test feasibility administering more detailed scale staggered manner so not unduly increase times. Methods: In this cross-sectional study, anonymized data sets were extracted from system. The participants adults (aged ≥18 years), scheduled nonurgent procedures performed hospitals United Kingdom, who gave consent their be analyzed. Data collected included age, gender, American Society Anesthesiology (ASA) physical classification status, time. Two user experience evaluations used: Phase 1, 2 questions asking about overall ease use, 2, previously questionnaire, with 20 equally distributed among 5 succeeding cohorts. There 2593 respondents total (Phase 1: n=1193; 2: n=1400). median age was 46 years, 1520 (58.62%) female. End points measured I II. by extracting subset records database exported spreadsheet analysis (Excel, Microsoft Corporation). analyzed differences between II, well groups, genders, ASA classifications. Results: scored both phases. 81.64% (974/1193) had good or better experience, 93.8% (1119/1193) found easy rating 4.13 out maximum 5, indicating high usability. 40.4 minutes. implementation longer did negatively impact Age status moderately associated increased Conclusions: rates method dividing into blocks valid does affect Further research affecting recommended.
