Evidence-based usability design principles for medication alerting systems.

BACKGROUND: Usability flaws in medication alerting systems may have a negative impact on clinical use and patient safety. In order to prevent the release of alerting systems that contain such flaws, it is necessary to provide designers and evaluators with evidence-based usability design principles. The objective of the present study was to develop a comprehensive, structured list of evidence-based usability design principles for medication alerting systems. METHODS: Nine sets of design principles for medication alerting systems were analyzed, summarized, and structured. We then matched the summarized principles with a list of usability flaws in order to determine the level of underlying evidence. RESULTS: Fifty-eight principles were summarized from the literature and two additional principles were defined, so that each flaw was matched with a principle. We organized the 60 summarized usability design principles into 6 meta-principles, 38 principles, and 16 sub-principles. Only 15 principles were not matched with a usability flaw. The 6 meta-principles respectively covered the improvement of the signal-to-noise ratio, the support for collaborative working, the fit with a clinician's workflow, the data display, the transparency of the alerting system, and the actionable tools to be provided within an alert. CONCLUSIONS: It is possible to develop an evidence-based, structured, comprehensive list of usability design principles that are specific to medication alerting systems and are illustrated by the corresponding usability flaws. This list represents an improvement over the current literature. Each principle is now associated with the best available evidence of its violation. This knowledge may help to improve the usability of medication alerting systems and, ultimately, decrease the harmful consequences of the systems' usability flaws.

Usability flaws of medication-related alerting functions: A systematic qualitative review.

INTRODUCTION: Medication-related alerting functions may include usability flaws that limit their optimal use. A first step on the way to preventing usability flaws is to understand the characteristics of these usability flaws. This systematic qualitative review aims to analyze the type of usability flaws found in medication-related alerting functions. METHOD: Papers were searched via PubMed, Scopus and Ergonomics Abstracts databases, along with references lists. Paper selection, data extraction and data analysis was performed by two to three Human Factors experts. Meaningful semantic units representing instances of usability flaws were the main data extracted. They were analyzed through qualitative methods: categorization following general usability heuristics and through an inductive process for the flaws specific to medication-related alerting functions. MAIN RESULTS: From the 6380 papers initially identified, 26 met all eligibility criteria. The analysis of the papers identified a total of 168 instances of usability flaws that could be classified into 13 categories of usability flaws representing either violations of general usability principles (i.e. they could be found in any system, e.g. guidance and workload issues) or infractions specific to medication-related alerting functions. The latter refer to issues of low signal-to-noise ratio, incomplete content of alerts, transparency, presentation mode and timing, missing alert features, tasks and control distribution. MAIN CONCLUSION: The list of 168 instances of usability flaws of medication-related alerting functions provides a source of knowledge for checking the usability of medication-related alerting functions during their design and evaluation process and ultimately constructs evidence-based usability design principles for these functions.

Issues and considerations for healthcare consumers using mobile applications.

There is a large and ever increasing number of mobile phone health, wellness, and medical applications on the market. However, there is little guidance or quality assurance available for consumers. This paper provides a health consumer focused framework for considering a range of issues associated with selecting and using mobile phone applications downloaded from the Internet.

Supporting cystic fibrosis with ICT.

ICT use in cystic fibrosis management provides an alternative means of information supply to individuals, families, health care professionals and other stakeholders. The purpose of this paper is to present the evolution of a series of projects culminating in a project that translates the previous research into practice. In this paper the sequential nature of the projects will be detailed. The three projects explored are the Pathways Home for Respiratory Illness Project (Pathways Home), Enhancing Self-Efficacy for Self-Management in People with Cystic Fibrosis and the Tasmanian Community Fund Project (myCF pilot).

The role of user-centred design within online community development.

Research has evidenced the benefits of using information and communications technology (ICT) in chronic disease management including improving information availability, communication methods and raising individual patient's self-awareness of their own conditions. Extending ICT use to support patients in the community through online services draws attention to the complex task of how to meaningfully acquire input from all potential users of such systems and to balance their competing interests. This paper explores these issues across system analysis, specification and design for a community based patient support system. The paper highlights user-centred design challenges in a situation where the patient-users were not able to be included during the planning stage and explores how this impacted on the subsequent development.

Health information overload among health consumers: A scoping review.

OBJECTIVE: To examine and identify the scope of research addressing health information overload in consumers. METHODS: In accordance with a published protocol, six electronic databases (PubMed, CINAHL, ERIC, PsycINFO, Embase, and Scopus), reference lists of included articles, and grey literature (Google Advanced Search and WorldCat) were searched. Articles in English were included, without any limit on the date of publication. RESULTS: Of the 69 records included for final analysis, 22 studies specifically examined health information overload, whereas the remainder peripherally discussed the concept alongside other concepts. The 22 studies focused on one or more of the following: 1) ways to measure health information overload (multi-item/single-item scales); 2) predictors of health information overload - these included low education level, health literacy, and socioeconomic status; and 3) interventions to address information overload, such as videotaped consultations or written materials. Cancer information overload was a popular topic amongst studies that focused on information overload. CONCLUSION: Based on the identified studies, there is a clear need for future studies that investigate health information overload in consumers with chronic medical conditions other than cancer. PRACTICE IMPLICATIONS: This review is the initial step in facilitating future efforts to create health information that do not overload consumers.

Design of a Consumer Mobile Health App for Heart Failure: Findings From the Nurse-Led Co-Design of Care4myHeart.

BACKGROUND: Consumer health care technology shows potential to improve outcomes for community-dwelling persons with chronic conditions, yet health app quality varies considerably. In partnership with patients and family caregivers, hospital clinicians developed Care4myHeart, a mobile health (mHealth) app for heart failure (HF) self-management. OBJECTIVE: The aim of this paper was to report the outcomes of the nurse-led design process in the form of the features and functions of the developed app, Care4myHeart. METHODS: Seven patients, four family caregivers, and seven multidisciplinary hospital clinicians collaborated in a design thinking process of innovation. The co-design process, involving interviews, design workshops, and prototype feedback sessions, incorporated the lived experience of stakeholders and evidence-based literature in a design that would be relevant and developed with rigor. RESULTS: The home screen displays the priority HF self-management components with a reminder summary, general information on the condition, and a settings tab. The health management section allows patients to list health care team member's contact details, schedule medical appointments, and store documents. The My Plan section contains nine important self-management components with a combination of information and advice pages, graphical representation of patient data, feedback, and more. The greatest strength of the co-design process to achieve the design outcomes was the involvement of local patients, family caregivers, and clinicians. Moreover, incorporating the literature, guidelines, and current practices into the design strengthened the relevance of the app to the health care context. However, the strength of context specificity is also a limitation to portability, and the final design is limited to the stakeholders involved in its development. CONCLUSIONS: We recommend health app development teams strategically incorporate relevant stakeholders and literature to design mHealth solutions that are rigorously designed from a solid evidence base and are relevant to those who will use or recommend their use.

Co-Design of a Mobile Health App for Heart Failure: Perspectives from the Team.

Using a Design Thinking and co-design methodology, hospital staff and consumers developed a novel mobile health app for heart failure self-management. Various stakeholders engaged in three development stages: interviews, design workshops and prototype iterations. Eleven of 18 co-design team members reflected on the co-design process and design outcomes. A total of 144 data points were collected: 96 about the co-design process and 48 about the design outcomes. Successes and failures reflect the strengths and weaknesses of operationalising co- design in practice. Overall, participants were surprised the design outcomes were achieved. The app was considered a supportive tool for meaningful self-monitoring and patients believed the app would be applicable to their situations. Our findings suggest that local co-design can be achieved through meaningful partnerships, and managing stakeholders was key to the projectâAZs success.

Patients' Experiences of Using a Consumer mHealth App for Self-Management of Heart Failure: Mixed-Methods Study.

BACKGROUND: To support the self-management of heart failure, a team of hospital clinicians, patients, and family caregivers have co-designed the consumer mobile health app, Care4myHeart. OBJECTIVE: This research aimed to determine patient experiences of using the app to self-manage heart failure. METHODS: Patients with heart failure used the app for 14 days on their own smart device in a home setting, following which a mixed-methods evaluation was performed. Eight patients were recruited, of whom six completed the Mobile Application Rating Scale and attended an interview. RESULTS: The overall app quality score was "acceptable" with 3.53 of 5 points, with the aesthetics (3.83/5) and information (3.78/5) subscales scoring the highest. The lowest mean score was in the app-specific subscale representing the perceived impact on health behavior change (2.53/5). Frequently used features were weight and fluid restriction tracking, with graphical representation of data particularly beneficial for improved self-awareness and ongoing learning. The use of technology for self-management will fundamentally differ from current practices and require a change in daily routines. However, app use was correlated with potential utility for daily management of illness with benefits of accurate recording and review of personal health data and as a communication tool for doctors to assist with care planning, as all medical information is available in one place. Technical considerations included participants' attitudes toward technology, functionality and data entry issues, and relatively minor suggested changes. CONCLUSIONS: The findings from this usability study suggest that a significant barrier to adoption is the lack of integration of technology into everyday life in the context of already established disease self-management routines. Future studies should explore the barriers to adoption and sustainability of consumer mobile health interventions for chronic conditions, particularly whether introducing such apps is more beneficial at the commencement of a self-management regimen.

REVIEW QUESTION/OBJECTIVE: The objective of this scoping review is to examine and map the breadth of evidence on information overload in lay adult and adolescent consumers of health-related information.

Popular Mobile Phone Apps for Diet and Weight Loss: A Content Analysis.

BACKGROUND: A review of the literature has revealed that the rates of overweight and obesity have been increasing in Australia over the last two decades and that wellness mobile phone apps play a significant role in monitoring and managing individuals' weight. Although mobile phone app markets (iTunes and Google Play) list thousands of mobile phone health apps, it is not always clear whether those apps are supported by credible sources. Likewise, despite the prevailing use of mobile phone apps to aid with weight management, the usability features of these apps are not well characterized. OBJECTIVE: The research explored how usability taxonomy could inform the popularity of downloaded, socially focused wellness mobile phone apps, in particular weight loss and diet apps. The aim of the study was to investigate the Australian mobile phone app stores (iTunes and Google Play) in order to examine the usability features of the most popular (ie, most downloaded) wellness apps. METHODS: The design of this study comprises 3 main stages: stage 1, identifying apps; stage 2, development of weight loss and diet evaluation framework; and stage 3, application of the evaluation framework. Each stage includes specific data collection, analysis tools, and techniques. RESULTS: The study has resulted in the development of a justified evaluation framework for weight loss and diet mobile phone apps. Applying the evaluation framework to the identified apps has shown that the most downloaded iTunes and Google Play apps are not necessarily the most usable or effective. In addition, the research found that search algorithms for iTunes and Google Play are biased toward apps' titles and keywords that do not accurately define the real functionality of the app. Moreover, the study has also analyzed the apps' user reviews, which served as justification for the developed evaluation framework. CONCLUSIONS: The analysis has shown that ease of use, reminder, bar code scanning, motivation, usable for all, and synchronization are significant attributes that should be included in weight loss and diet mobile phone apps and ultimately in potential weight loss and diet evaluation frameworks.

Value versus Use for Patients: Findings from an ICT supported Cystic Fibrosis Self-Management Project.

This paper presents findings from the implementation of an online symptom monitoring diary that was part of a broader project aimed to support self-management of cystic fibrosis and the development of an online community of practice (CoP). The findings challenge conventional perspectives on how value is acquired by patients and their families from electronic tools designed to provide them with support. Additionally, the findings highlight complex relationships between user needs and subsequent tool use that challenge approaches to the measurement of value from ehealth projects.

Patient Centred Systems: Techno-Anthropological reflections on the challenges of 'meaningfully engaging' patients within health informatics research.

This chapter explores how Techno-Anthropology can contribute to more explicitly professional and ethically responsible reflections on the socio-technical practices involved in meaningfully engaging patients in health informatics research. The chapter draws on insights from health informatics research projects focused on chronic disease and self-management conducted in Tasmania during the last 10 years. Through these projects the paper explores three topics of relevance to 'meaningful engagement' with patients: (i) Patient Self-Management and Chronic Disease (ii) Patients as Users in Health Informatics research, and, (iii) Evaluations of outcomes in Health and Health Informatics Interventions. Techno-Anthropological reflections are then discussed through the concepts of liminality, polyphony and power. This chapter argues that beyond its contribution to methodology, an important role for Techno-Anthropology in patient centred health informatics research may be its capacity to support new ways of conceptualising and critically reflecting on the construction and mediation of patients' needs, values and perspectives.

Pilot evaluation of web enabled symptom monitoring in cystic fibrosis.

BACKGROUND: People with cystic fibrosis (CF) frequently experience isolation and are subjected to extensive complex treatment regimens which could be complemented by remote support. In the current research this is particularly relevant as the location, Tasmania, has the second highest incidence of CF in the world. This paper provides an overview of the evaluation of a pilot trial of an information system conceptualised and developed to assist people with CF, and their families, to enhance their skills and communication in relation to self-management for their condition. METHODS: The pilot involved people with CF ranging in age from 19 months to 52 years and their families. The primary outcome was the perceived usability of the online-symptom diary from the user's perspective. To assess perceived usability qualitative semi-structured interviews were conducted pre- and post-pilot and analysed using thematic coding. RESULTS: Participants initially and primarily perceived myCF as a system that would help others and enable peer support. Connectivity and involvement were highlighted as complex issues that needed consideration. CONCLUSION: There was an overall encouraging response to the pilot and indications that the use of information communication technology to complement health care delivery and facilitate self-care skills may be particularly suited to the Australian context where geographical distances and isolation provide a relative barrier to specialist care for chronic complex conditions.
