“…This gap can be bridged through user-centered design approaches, where designers and users are brought together in the early system development phase to communicate directly. [24][25][26] User-centered design, however, can be time and resource consuming and is not always feasible for the development of interactive dashboards. This leads to inevitable differences in mental models that create usability issues and the need for comparing the mental models when examining underlying reasons for usability issues.…”

Background Interactive data visualization and dashboards can be an effective way to explore meaningful patterns in large clinical data sets and to inform quality improvement initiatives. However, these interactive dashboards may have usability issues that undermine their effectiveness. These usability issues can be attributed to mismatched mental models between the designers and the users. Unfortunately, very few evaluation studies in visual analytics have specifically examined such mismatches between these two groups. Objectives We aimed to evaluate the usability of an interactive surgical dashboard and to seek opportunities for improvement. We also aimed to provide empirical evidence to demonstrate the mismatched mental models between the designers and the users of the dashboard. Methods An interactive dashboard was developed in a large congenital heart center. This dashboard provides real-time, interactive access to clinical outcomes data for the surgical program. A mixed-method, two-phase study was conducted to collect user feedback. A group of designers (N = 3) and a purposeful sample of users (N = 12) were recruited. The qualitative data were analyzed thematically. The dashboards were compared using the System Usability Scale (SUS) and qualitative data. Results The participating users gave an average SUS score of 82.9 on the new dashboard and 63.5 on the existing dashboard (p = 0.006). The participants achieved high task accuracy when using the new dashboard. The qualitative analysis revealed three opportunities for improvement. The data analysis and triangulation provided empirical evidence to the mismatched mental models. Conclusion We conducted a mixed-method usability study on an interactive surgical dashboard and identified areas of improvements. Our study design can be an effective and efficient way to evaluate visual analytics systems in health care. We encourage researchers and practitioners to conduct user-centered evaluation and implement education plans to mitigate potential usability challenges and increase user satisfaction and adoption.

“…Previous studies have shown a positive correlation between awareness levels and compliance among patients with diabetes; good disease awareness can improve a patient's treatment compliance, thus facilitating the patient's treatment. 22,23 One study showed that the extended nursing model, based on applications, could effectively improve a patients' cognition of their own disease. 24 Continuous care for patients with type 2 diabetes using mobile health application could provide diversified health education, stable follow-up systems, and professional medical and resource supports, leading to improvements in patient cognition and improved selfmanagement.…”

Summary Background Type 2 diabetes is a worldwide disorder that affects millions of people and can exert negative clinical and social effects on the patients. In some previous studies, mobile health applications have been used as a means of clinical intervention. However, the therapeutic effect of continuous care through mobile phone applications for patients with type 2 diabetes remains unclear. Objective This study aimed to explore the clinical effect of continuous care for patients with type 2 diabetes using mobile health application by comparing traditional discharge nursing. Methods In total, 120 patients with type 2 diabetes were randomly divided into two groups: The test group received continuous care based on the mobile phone application (n = 60), and the control group received conventional care (n = 60). Primary clinical outcomes, such as Glycaemic Haemoglobin (GH) levels, blood glucose levels, self‐care abilities, disease cognition abilities, and the number of readmissions, were examined in both groups. Results The results showed significant improvements pertaining to disease awareness levels (81.28 vs 71.34, P < .05), self‐management abilities (9.14 vs 7.81, P < .05), GH (−1.50% vs −0.76%, P < .05), fast blood glucose (−3.23 vs −1.25 mmol/L, P < .05), postprandial blood glucose levels (−4.34 vs −2.34 mmol, P < .05), and control levels in the test group. Moreover, in the test group, the frequency of rehospitalisation was reduced during the intervention period, as was the average number of rehospitalisation within 6 months after discharge (−1.19 vs P < .05). Conclusions Continuous care based on a mobile health application has potential as a management strategy for patients with type 2 diabetes.

The use of digital technology has been shown to be effective in managing chronic conditions. Telemedicine and mobile application are two common applications of digital technology in managing diabetic foot ulcers (DFU). The facilitators and barriers of using it for DFU management are yet to be explored. This is a qualitative systematic review. Five bibliography databases and grey literature sources were searched (2000‐2019). Two reviewers independently screened the citations, extracted the data, assessed the quality of the included studies, and performed thematic synthesis. Three studies on patients and five studies on healthcare practitioners (HCPs) were included. Two studies focused on the use of mobile applications and six on telemedicine. In studies on patients, four analytical themes were generated: the relationships with HCPs; the attitude towards the usage of digital technology; the role of wound image taking; and impact of digital technology on DFU care, encompassing 15 facilitators (eg, enabling community support, improving wound care knowledge) and 12 barriers (eg, lack of technological savviness, difficulty reading on smartphones). Three analytical themes were generated from studies on HCPs: the impact of digital technology on HCPs; the role of digital technology in DFU care; and organisation of DFU care delivery, encompassing 17 facilitators (eg, adequate wound care training, digital technology enables holistic care) and 16 barriers (eg, lack of multidisciplinary approach in caring for DFU, lack of direct contact in care provision). Patients and HCPs reported various barriers and facilitators relating to different aspects of using digital technology in DFU management. Our findings can help inform future research as well as the adoption of digital technology in DFU management.
