RESUMO
BACKGROUND AND OBJECTIVES: We describe the development of Preanestes@s, a web-based application for preoperative assessment, which incorporates PreQuest, a smart computer-based self-assessment questionnaire for the automated management of information. Preanestes@s potentially enables remote non-telephonic preoperative assessment. The main objective of this work was the identification of factors that independently predict adequate completion of PreQuest. As a secondary objective, we assessed patient experience using the application. MATERIAL AND METHODS: To assess the influence of patient conditions on PreQuest completion, our sample included 880 adult patients scheduled to undergo surgery at our institution between February 2020 and February 2021. We evaluated patient satisfaction and acceptability with the use of the application and PreQuest. RESULTS: A total of 573 participants (65.1%) successfully completed the PreQuest. Age below 65 years and higher educational attainment were identified as independent predictors for PreQuest completion (p = 0.04 and p = 0.001, respectively). Most (89.4%) participants agreed that Preanestes@s was intuitive and easy to use, with over 85% showing high levels of acceptance of PreQuest prototype's communication improvement and ease of use. The final version of Preanestes@s and PreQuest was evaluated by 218 participants, many of whom (>74%) affirmed its ease of use. CONCLUSIONS: The use of Preanestes@s for preoperative assessment is supported by high levels of satisfaction with the prototype and by an eQuest completion rate greater than 65% in a non-selective population. In our sample, younger age and higher education attainment predicted higher rates PreQuest completion. Trial registration number NCT04259268.
