Integrating Information Systems and Healthcare Research to Understand Physicians’ use of Health Information Systems: a Literature Review

Healthcare has been of great importance to societies for centuries and this importance is reflected in the abundance of healthcare research that involves, not only new interventions, but clinicians’ response to change in the medical practice as well. Information systems (IS) research failed to take full advantage of healthcare research focusing on studying IS as an intervention or change in clinical workflows. To fill this gap, we conducted an extensive literature survey in both IS and healthcare research which included 175 papers from healthcare, IS journals and conferences that study physicians’ use of HIS and clinical guidelines. Results of this review show that there are two different streams of HIS research in IS and healthcare domains and by integrating those streams we can create a rich understanding of HIS use. We build a model for HIS use based on our review and provide areas for future research

Knowledge-Based Clinical Decision Support Systems Continuance: An Integration of Physicians’ Identity and System Attributes

Despite the importance of sustained use of healthcare information systems, research on the continuous use of these systems is scanty, especially for clinical decision support systems. Moreover, there is an apparent gap between information systems and healthcare research approaches in studying use. We address these gaps by creating a comprehensive model based on the composite attitude-behavior model that integrates system related constructs with physicians’ professional identity constructs to explain and model physicians’ continuous use of a pain management clinical decision support system theoretically. Using a mixed methods longitudinal study design, we investigate factors influencing continuous use of automated clinical guidelines. The potential contributions of this study include enhancing our understanding of factors influencing physicians’ continuance behavior, and providing guidance on developing effective automated knowledge-based clinical decision support

A Clinical Decision Support System for Chronic Pain Management in Primary Care: Usability testing and its relevance

Background Clinical decision support systems (CDSSs) that are integrated into electronic medical records may be useful for encouraging practice change compliant with clinical practice guidelines.Objective To engage end users to inform early phase CDSS development through a process of usability testing.Method A sequential exploratory mixed method approach was used. Interprofessional clinician participants (seven in iteration 1 and six in iteration 2) were asked to ‘think aloud’ while performing various tasks on the CDSS and then complete the System Usability Scale (SUS). Changes were made to the CDSS after each iteration.Results Barriers and facilitators were identified: systemic; user interface (most numerous barriers); content (most numerous facilitators) and technical. The mean SUS score was 81.1 (SD = 12.02) in iteration 1 and 70.40 (SD = 6.78) in iteration 2 (p > 0.05).Conclusions Qualitative data from usability testing were valuable in the CDSS development process. SUS scores were of limited value at this development stage.

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
