Background In this pilot study, we investigated sociotechnical factors that affect intention to use a simplified web model to support clinical decision making. Objective We investigated factors that are known to affect technology adoption using the unified theory of acceptance and use of technology (UTAUT2) model. The goal was to pilot and test a tool to better support complex clinical assessments. Methods Based on the results of a previously published work, we developed a web-based mobile user interface, WebModel, to allow users to work with regression equations and their predictions to evaluate the impact of various characteristics or treatments on key outcomes (eg, survival time) for chronic obstructive pulmonary disease. The WebModel provides a way to combat information overload and more easily compare treatment options. It limits the number of web forms presented to a user to between 1 and 20, rather than the dozens of detailed calculations typically required. The WebModel uses responsive design and can be used on multiple devices. To test the WebModel, we designed a questionnaire to probe the efficacy of the WebModel and assess the usability and usefulness of the system. The study was live for one month, and participants had access to it over that time. The questionnaire was administered online, and data from 674 clinical users who had access to the WebModel were captured. SPSS and R were used for statistical analysis. Results The regression model developed from UTAUT2 constructs was a fit. Specifically, five of the seven factors were significant positive coefficients in the regression: performance expectancy (β=.2730; t=7.994; P<.001), effort expectancy (β=.1473; t=3.870; P=.001), facilitating conditions (β=.1644; t=3.849; P<.001), hedonic motivation (β=.2321; t=3.991; P<.001), and habit (β=.2943; t=12.732). Social influence was not a significant factor, while price value had a significant negative influence on intention to use the WebModel. Conclusions Our results indicate that multiple influences impact positive response to the system, many of which relate to the efficiency of the interface to provide clear information. Although we found that the price value was a negative factor, it is possible this was due to the removal of health workers from purchasing decisions. Given that this was a pilot test, and that the system was not used in a clinical setting, we could not examine factors related to actual workflow, patient safety, or social influence. This study shows that the concept of a simplified WebModel could be effective and efficient in reducing information overload in complex clinical decision making. We recommend further study to test this in a clinical setting and gather qualitative data from users regarding the value of the tool in practice.

Information overload negatively affects clinicians’ decision effectiveness and ultimately impacts patient safety. Clinicians who are tasked with assessing patient outcomes are often required to use complex outcome and risk models in a spreadsheet format. In response to this challenge, we developed a mobile web model which simplifies the information presented to clinicians and expedites the decision process. However, new electronic technologies often face barriers to adoption which inhibits their use in clinical settings. This pilot study investigated sociotechnical factors that affect intention to use a simplified WebModel to support clinical decision making. We investigated factors from the UTAUT2 model, which are known to affect technology adoption. A WebModel is developed based on the results from a previously published work, to allow users to work with regression equations and their predictions to evaluate the impact of various characteristics or treatments on key outcomes (e.g. survival time) for chronic obstructive pulmonary disease (COPD). To test the WebModel a questionnaire was designed to probe the efficacy of the WebModel and to assess the usability and usefulness of the system. The questionnaire was administered online, and data from 550 clinical users who had access to the WebModel was captured. SPSS and R were used for statistical analysis. The regression model developed from UTAUT2 constructs was found to be a fit, with five variables found to significantly predicts behavioural intention to sue the WebModel: Performance Expectancy, Effort Expectancy, Facilitating Conditions, Hedonic Motivation and Habit. Social Influence was not a significant factor, while Value had a significant negative influence on intention to use the WebModel. Multiple influences were found to impact the positive response to the system, many of which related to the efficiency of the interface to provide clear information. Given that this was a pilot test, and that the system was not used in a clinical setting factors related to actual workflow, or patient safety could not be examined. This study proves that the concept of a simplified WebModel could be effective and efficient in reducing information overload in complex clinical decision making. Further study to test this in a clinical setting, and gather qualitative data from users regarding the value of the tool in practice is recommended.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
