Earlier self-reporting App case studies
Craven, M. P., Selvarajah, K., Miles, R., Schnädelbach, H., Massey, A., Vedhara, K., Raine-Fenning, N., Crowe, J. User requirements for the development of Smartphone self-reporting applications in healthcare, in Kurosu, M (Ed.): Human-Computer Interaction, Part II, HCII 2013, LNCS 8005, 36-45, 2013.
![Page 11: User requirements for smartphone apps](https://reader035.fdocuments.in/reader035/viewer/2022062313/55757df8d8b42adb7e8b4ed2/html5/thumbnails/11.jpg)
The problem of user elicitation
11
Perceptions• Limited involvement of health professional involvement during App development
(Rosser et al. J. Telemed Telecare, 2011 - Pain Apps survey) • Lack of end user involvement in the App design process (McCurdie et al. AAMI Horizons
2012)• Little good quality evidence for mHealth interventions used by ‘lay people’. Text
messaging services shown to increase adherence to anti-retroviral medication in low cost setting, increase smoking cessation in high cost setting (Free et al. PLOS Medicine, 2013)
Demands• Regulatory (for ‘medical device’ Apps) e.g. HE75, IEC 62366:2007 - Medical devices --
Application of usability• Patient Public Involvement – imperative for NIHR research• Implementation science (Brooks et al. 2011 – ‘conducive’ & ‘impeding’ conditions for
innovation in mental health services)• Ethical (Wenze & Miller 2010 - ecological momentary assessment in mood disorders
research)
![Page 12: User requirements for smartphone apps](https://reader035.fdocuments.in/reader035/viewer/2022062313/55757df8d8b42adb7e8b4ed2/html5/thumbnails/12.jpg)
Ethical issues with Apps
• Security – data storage and communication. Apps vs. text messaging & email (also a regulatory issue)
• Privacy - What do patients/participants expect or imagine might happen with their data e.g. a trained professional monitoring it and acting upon it.
• Sensitive information - maybe better revealed face-to-face, in a group situation …?
• Burden - what frequency of data collection is acceptable?• Impact on clinical care - how to respond to results of data collection: do
nothing, give advice, treat as an emergency?• Impact on health – stress, being reminded could cause exacerbation,
constant reminder of condition?• Social – effect on family, carers etc.

Case study 1 – phone audit for IVF Stress App
14
• 10 questions (76 users):– What type/model of mobile phone do you
have? – Is your mobile phone a smart phone?– Which air time provider are you with?– Is the phone on pay as you go or on
contract?– Do you use email or internet access on your
phone?– Is internet coverage included in your
contract?– Do you use an alarm clock function?– Are you familiar with the use of ‘Apps’ on
your phone?– How regularly do you use an ‘App’ on your
phone?– If you were to be asked to report your
distress levels throughout your treatment which of the following methods would you prefer?

Case study 2 – mild asthma study
16
• Week 1 – diary only • Week 2 – diary + physiological measures
Each weekday evening: • complete diary entry
on smartphone (questionnaire modified from Juniper et al. 1992)
Each weekday morning & evening: • Take 3 PEF measurements and enter data• Record 5 mins of pulse oximeter data
Each weekday evening: complete diary entry

Case study 2 – mild asthma - user experience (results)Mild asthma self-reporting App study (with BlueTooth pulse oximeter device)
• 5/11 participants - technology ‘nice’ or ‘easy to use’. – 2 ‘interesting’– 6 minor technical problem (internet/Wi-Fi, Bluetooth, battery)– 1 not confident data upload succeeded– 1 ‘sometimes a bit of a hassle … overkill for mild asthma’
• 5/11 participants - no effect on lifestyle or ‘got used to it’ – 1 more cautious about remembering inhaler– 1 needed to plan when going out– 1 interference with daily activities– 2 difficulty or annoyance scheduling the recordings correctly– 1 inconvenience of sitting down to take measurements
• 11/11 - no effect of technology on condition– 1 reported exacerbation during the study.
• 7/11 - more aware of condition whilst taking part. – 2 ‘a good thing’. – 1 ‘thinking about a cough exacerbates it’.

Towards a protocol
• Conduct a phone audit before commencing a research study – Discover range of prior experiences & preferences for phone functions amongst participants (e.g. alarm
clock)– Detect potential for conflict between normal daily use & research study use of phone (since functions
may mix or conflict)
• Investigate design tolerance to real-world phone use amongst user group– Not keeping devices turned on or charged up – Effect of missing or ignoring prompts
• Ensure secure collection and storage of data – Pre-empt ethical approval issues
• Determine patient burden and adherence – Frequency of self-monitoring prompts– Pilot studies aimed at measuring adherence– Could more passive monitoring be preferable?
Early stage user involvement and/or a participatory design process helps reveal needs which may not initially be apparent
