User experience and user acceptance of a speech recognition-based diagnostic management application: mobile health at point-of-care (Preprint)

Abstract

BACKGROUND In-patient management like ordering medical tests is time-consuming and burdens physicians on the ward with non-clinical tasks. We developed and implemented a smartphone-based mobile application (MA) that uses speech recognition for the ordering of radiological examinations. While we could show that the MA supported process was faster, its acceptance and usability remaines unknown. OBJECTIVE We examined the user experience (1), user acceptance (2) and the determinants of user acceptance (3) of a new mobile, speech recognition guided in-patient management MA. METHODS A comprehensive questionnaire based on the short version of the User Experience Questionnaire (UEQ-S) and the Unified Theory of Acceptance and use of Technology (UTAUT) was given to all physicians at the Department of Trauma and Plastic Surgery at the University Hospital of Wuerzburg , Germany. The user experience with the new MA was compared to the usual desktop application (DA) workflow embedded in the clinical information system (i.s.h.med, Cerner Health Services Deutschland GmbH, Berlin, Germany). The domains of user experience consisted of overall attractiveness, pragmatic quality, and hedonic quality. For the determinants of the acceptance model, we employed hierarchical regression analysis. RESULTS Twenty-one out of 30 physicians (mean age 34±8 years, 62% male) completed the questionnaire (response rate 70%). Compared to the conventional DA workflow, the new MA showed superior overall attractiveness (mean difference +2.15±1.33), pragmatic quality (mean difference +1.90±1.16), hedonic quality (mean difference 2.41±1.62; all p<.001). The user acceptance measured by the UTAUT (mean 4.49, SD 0.41; min. 1, max. 5) was also high. Performance expectancy (beta=0.57, p=.02) and effort expectancy (beta=0.36, p=.04) were identified as predictors of acceptance explaining 65.4% of its variance. CONCLUSIONS There is huge potential in reducing the physicians’ burden of administrative tasks by adopting innovative DHI like our speech recognition guided MA in daily ward routine. With this study, we could illustrate that physicians are more than willing to implement such innovative mobile health solutions.

Mobile-linked point-of-care diagnostics in community-based healthcare: A scoping review of user experiences

“…The studies presented evidence on user experiences of m-linked POC diagnostics. The included articles comprised two cross-sectional studies [24,25], two qualitative studies [26,27], a cohort study [28], three surveys [29][30][31], and one mixed method study [32].…”

“…190 The included studies were conducted in various countries (Fig 2). Three studies were conducted in the United States of America (USA) [25,27,31], one in Ghana [26], one in South Africa [24], one in the United Kingdom (UK) [29], one in Australia [32], and one in Germany [30]. A cohort study by Jacobson et al (2020) also reported findings from the USA, Australia, Germany, Italy, Spain, Ireland, Brazil, Portugal, India, and Argentina [28].…”

“…The m-linked POC diagnostic technology presented in the included studies was focused on the following diagnostics (Fig. 3): cervicography [26], tuberculosis [24], tumor stage [28], infectious diseases surveillance [29], speech recognition for diagnostic purposes [30],…”

“…4). The community healthcare settings were emergency care units and departments [25,31], community healthcare centers [26], developing and underresourced contextual settings [24], the European Immuno-oncology Clinic CME community [28], infectious disease testing sites [29], a trauma and plastic surgery department [30],…”

“…postoperative recovery [27], and hospital settings [32]. The included studies focused on students (10%) [24], nurses (20%) [26,32], patients (30%) [26,31], healthcare professionals (20%) [28,30], experts and key stakeholders (20%) [27,29], as well as socioeconomically disadvantaged inner-city populations.…”
