TL;DR: In this paper, a mobile health app for patients with hemophilia A was developed and validated using a focus group to evaluate the relationship between physical activity levels and bleeding in patients.
Abstract: Background: There is currently limited evidence on the level and intensity of physical activity in individuals with hemophilia A. Mobile technologies can offer a rigorous and reliable alternative to support data collection processes but they are often associated with poor user retention. The lack of longitudinal continuity in their use can be partly attributed to the insufficient consideration of stakeholder inputs in the development process of mobile apps. Several user-centered models have been proposed to guarantee that a thorough knowledge of the end user needs is considered in the development process of mobile apps. Objective: The aim of this study is to design and validate an electronic patient-reported outcome mobile app that requires sustained active input by individuals during POWER, an observational study that aims at evaluating the relationship between physical activity levels and bleeding in patients with hemophilia A. Methods: We adopted a user-centered design and engaged several stakeholders in the development and usability testing of this mobile app. During the concept generation and ideation phase, we organized a need-assessment focus group (FG) with patient representatives to elicit specific design requirements for the end users. We then conducted 2 exploratory FGs to seek additional inputs for the app’s improvement and 2 confirmatory FGs to validate the app and test its usability in the field through the mobile health app usability questionnaire. Results: The findings from the thematic analysis of the need-assessment FG revealed that there was a demand for sense making, for simplification of app functionalities, for maximizing integration, and for minimizing the feeling of external control. Participants involved in the later stages of the design refinement contributed to improving the design further by upgrading the app’s layout and making the experience with the app more efficient through functions such as chatbots and visual feedback on the number of hours a wearable device had been worn, to ensure that the observed data were actually registered. The end users rated the app highly during the quantitative assessment, with an average mobile health app usability questionnaire score of 5.32 (SD 0.66; range 4.44-6.23) and 6.20 (SD 0.43; range 5.72-6.88) out of 7 in the 2 iterative usability testing cycles. Conclusions: The results of the usability test indicated a high, growing satisfaction with the electronic patient-reported outcome app. The adoption of a thorough user-centered design process using several types of FGs helped maximize the likelihood of sustained retention of the app’s users and made it fit for data collection of relevant outcomes in the observational POWER study. The continuous use of the app and the actual level of engagement will be evaluated during the ongoing trial.

TL;DR: In this article, a systematic review examined the developmental considerations adopted in trials that engaged mobile phone applications for diabetes self-management and identified a total of 11 studies (10 randomized controlled trials and 1 quasi-experimental trial) that fitted the inclusion criteria were identified.
Abstract: Background: There is increased research interest in the use of mobile phone apps to support diabetes management. However, there are divergent views on what constitute the minimum standards for inclusion in the development of mobile phone apps. Mobile phone apps require an evidence-based approach to development which will consequently impact on their effectiveness. Therefore, comprehensive information on developmental considerations could help designers and researchers to develop innovative and effective patient-centered self-management mobile phone apps for diabetes patients. Objective: This systematic review examined the developmental considerations adopted in trials that engaged mobile phone applications for diabetes self-management. Methods: A comprehensive search strategy was implemented across 5 electronic databases; Medline, Scopus, Social Science Citation Index, the Cochrane Central Register of Controlled Trials and Cumulative Index of Nursing and Allied Health Literature (CINALHL) and supplemented by reference list from identified studies. Study quality was evaluated using the Joanna Briggs Critical appraisal checklist for trials. Information on developmental factors (health behavioral theory, functionality, pilot testing, user and clinical expert involvements, data privacy and app security) were assessed across experimental studies using a template developed for the review. Results: A total of 11 studies (10 randomized controlled trials and 1 quasi-experimental trial) that fitted the inclusion criteria were identified. All the included studies had the functionality of self-monitoring of blood glucose. However, only some of them included functions for data analytics (7/11, 63.6%), education (6/11, 54.5%) and reminder (6/11, 54.5%). There were 5/11(45.5%) studies with significantly improved glycosylated hemoglobin in the intervention groups where educational functionality was present in the apps used in the 5 trials. Only 1 (1/11, 9.1%) study considered health behavioral theory and user involvement, while 2 (2/11, 18.1%) other studies reported the involvement of clinical experts in the development of their apps. There were 4 (4/11, 36.4%) studies which referred to data security and privacy considerations during their app development while 7 (7/12, 63.6%) studies provided information on pilot testing of apps before use in the full trial. Overall, none of the studies provided information on all developmental factors assessed in the review. Conclusions: There is a lack of elaborate and detailed information in the literature regarding the factors considered in the development of apps used as interventions for diabetes self-management. Documentation and inclusion of such vital information will foster a transparent and shared decision-making process that will ultimately lead to the development of practical and user-friendly self-management apps that can enhance the quality of life for diabetes patients.

TL;DR: In this paper , the authors developed and evaluated a smartphone app (Lion-App) to enable cancer patients to autonomously measure mental health and quality of life (QoL) with an iterative, user-centered approach.
Abstract: BACKGROUND The cure for cancer can not only have a negative impact on physical wellbeing, but also on mental health and quality of life (QoL). Health apps enable the monitoring of different parameters, but to date there are only few which support cancer patients and none that focus on QoL. Furthermore, patients as stakeholders are often only integrated at late stage of the development process, if at all. OBJECTIVE The aim of this research was to develop and evaluate a smartphone app (Lion-App) to enable cancer patients to autonomously measure QoL with an iterative, user-centered approach. The goal was to closely integrate end users into every stage of the development process, in order to be able to use the information gained for further development cycles to implement an applicable solution tailored to the needs of end-users. METHODS Cancer patients were included from conceptualization through different development phases in a three-staging process: First, focus groups with cancer support-groups were conducted to understand their expectations and needs. Thereafter, individual tests were performed. After developing a prototype that incorporated first findings, a second test was conducted followed by a beta test lasting several weeks. Participants could download a beta version and test it on their private devices. Lion-App assesses QoL via a patient diary and integrated questionnaires. Through all stages usability was evaluated through the modular User Experience Questionnaire (UEQ+), including the calculation of a key performance indicator (KPI). If possible, the impact of sex on the results was assessed. In the beta test, usage rates as well as age dependent differences were evaluated. RESULTS A total of 21 participants took part in the first focus groups. For the subsequent user test, 17 participants rated their impression through the UEQ+ questionnaire with a KPI [-3,3] of 2.12. In the second usability test, the KPI increased to 2.28. Within the beta test, the usage rate of 19 participants could be evaluated, of whom 14 also answered the UEQ+ (KPI=1.46). An influence of age for the number of questionnaire responses within the app were seen with a decrease of responses with increasing age (P=.02). Sex dependent analysis were only possible for the first - and beta test. CONCLUSIONS The iterative, user-centered approach for development and usability testing has been reflected in positive end-user evaluations. We have successfully developed an App suitable for everyday use to monitor QoL of cancer patients. First results indicated that sex or age of participants seem to play only a minor role. Our approach as well as the findings can be applied to other projects to develop solutions tailored to the end-user.
