User interface design for mobile-based sexual health interventions for young people: Design recommendations from a qualitative study on an online Chlamydia clinical care pathway

Background: The increasing pervasiveness of mobile technologies has given potential to transform healthcare by facilitating clinical management using software applications. These technologies may provide valuable tools in sexual health care and potentially overcome existing practical and cultural barriers to routine testing for sexually transmitted infections. In order to inform the design of a mobile health application for STIs that supports self-testing and self-management by linking diagnosis with online care pathways, we aimed to identify the dimensions and range of preferences for user interface design features among young people. Methods: Nine focus group discussions were conducted (n=49) with two age-stratified samples (16 to 18 and 19 to 24 year olds) of young people from Further Education colleges and Higher Education establishments. Discussions explored young people's views with regard to: the software interface; the presentation of information; and the ordering of interaction steps. Discussions were audio recorded and transcribed verbatim. Interview transcripts were analysed using thematic analysis. Results: Four over-arching themes emerged: privacy and security; credibility; user journey support; and the task-technology-context fit. From these themes, 20 user interface design recommendations for mobile health applications are proposed. For participants, although privacy was a major concern, security was not perceived as a major potential barrier as participants were generally unaware of potential security threats and inherently trusted new technology. Customisation also emerged as a key design preference to increase attractiveness and acceptability. Conclusions: Considerable effort should be focused on designing healthcare applications from the patient's perspective to maximise acceptability. The design recommendations proposed in this paper provide a valuable point of reference for the health design community to inform development of mobile-based health interventions for the diagnosis and treatment of a number of other conditions for this target group, while stimulating conversation across multidisciplinary communities

The eClinical Care Pathway Framework: A novel structure for creation of online complex clinical care pathways and its application in the management of sexually transmitted infections.

Despite considerable international eHealth impetus, there is no guidance on the development of online clinical care pathways. Advances in diagnostics now enable self-testing with home diagnosis, to which comprehensive online clinical care could be linked, facilitating completely self-directed, remote care. We describe a new framework for developing complex online clinical care pathways and its application to clinical management of people with genital chlamydia infection, the commonest sexually transmitted infection (STI) in England.Using the existing evidence-base, guidelines and examples from contemporary clinical practice, we developed the eClinical Care Pathway Framework, a nine-step iterative process. Step 1: define the aims of the online pathway; Step 2: define the functional units; Step 3: draft the clinical consultation; Step 4: expert review; Step 5: cognitive testing; Step 6: user-centred interface testing; Step 7: specification development; Step 8: software testing, usability testing and further comprehension testing; Step 9: piloting. We then applied the Framework to create a chlamydia online clinical care pathway (Online Chlamydia Pathway).Use of the Framework elucidated content and structure of the care pathway and identified the need for significant changes in sequences of care (Traditional: history, diagnosis, information versus Online: diagnosis, information, history) and prescribing safety assessment. The Framework met the needs of complex STI management and enabled development of a multi-faceted, fully-automated consultation.The Framework provides a comprehensive structure on which complex online care pathways such as those needed for STI management, which involve clinical services, public health surveillance functions and third party (sexual partner) management, can be developed to meet national clinical and public health standards. The Online Chlamydia Pathway's standardised method of collecting data on demographics and sexual behaviour, with potential for interoperability with surveillance systems, could be a powerful tool for public health and clinical management.UKCRC Translational Infection Research (TIR) Initiative supported by the Medical Research Council, eSTI2 Consortium (Grant Number G0901608)

Are HIV smartphone apps and online interventions fit for purpose?

Sexual health is an under-explored area of Human-Computer Interaction (HCI), particularly sexually transmitted infections such as HIV. Due to the stigma associated with these infections, people are often motivated to seek information online. With the rise of smartphone and web apps, there is enormous potential for technology to provide easily accessible information and resources. However, using online information raises important concerns about the trustworthiness of these resources and whether they are fit for purpose. We conducted a review of smartphone and web apps to investigate the landscape of currently available online apps and whether they meet the diverse needs of people seeking information on HIV online. Our functionality review revealed that existing technology interventions have a one-size-fits-all approach and do not support the breadth and complexity of HIV-related support needs. We argue that technology-based interventions need to signpost their offering and provide tailored support for different stages of HIV, including prevention, testing, diagnosis and management

Mixed-methods evaluation of a novel online STI results service.

OBJECTIVES: Evidence on optimal methods for providing STI test results is lacking. We evaluated an online results service, developed as part of an eSexual Health Clinic (eSHC). METHODS: We evaluated the online results service using a mixed-methods approach within large exploratory studies of the eSHC. Participants were chlamydia- positive and negative users of online postal self-sampling services in six National Chlamydia Screening Programme (NCSP) areas and chlamydia-positive patients from two genitourinary medicine (GUM) clinics between 21 July 2014 and 13 March 2015. Participants received a discreetly worded National Health Service 'NHS no-reply' text message (SMS) informing them that their test results were ready and providing a weblink to a secure website. Participants logged in with their date of birth and mobile telephone or clinic number. Chlamydia-positive patients were offered online management. All interactions with the eSHC system were automatically logged and their timing recorded. Post-treatment, a service evaluation survey (n=152) and qualitative interviews (n=36) were conducted by telephone. Chlamydia-negative patients were offered a short online survey (n=274). Data were integrated. RESULTS: 92% (134/146) of NCSP chlamydia-positive patients, 82% (161/197) of GUM chlamydia-positive patients and 89% (1776/1997) of NCSP chlamydia-negative participants accessed test results within 7 days. 91% of chlamydia-positive patients were happy with the results service; 64% of those who had tested previously found the results service better or much better than previous experiences. 90% of chlamydia-negative survey participants agreed they would be happy to receive results this way in the future. Interviewees described accessing results with ease and appreciated the privacy and control the two-step process gave them. CONCLUSION: A discreet SMS to alert users/patients that results are available, followed by provision of results via a secure website, was highly acceptable, irrespective of test result and testing history. The eSHC results service afforded users privacy and control over when they viewed results without compromising access

Design Recommendations for an Inclusive Online Sexual Health Clinic for Blind and Partially Sighted People

Sexually transmitted infections are highly prevalent in the United Kingdom, and chlamydia, which is largely asymptomatic, is the most common. Digital health is being integrated into health service provision to support the increasing demand for testing and treatment. However, with this integration, there is a need to ensure that the design, development, and deployment of digital health platforms are inclusive and accessible for all. This paper explores the needs of blind and partially sighted people when using an online sexual health clinic through interviews with seven blind and partially sighted people. The findings identified key barriers and facilitators that impact the accessibility of online sexual health clinics, including the accessibility of the visual content, particularly for self-testing and the need to consider the privacy of disclosing sexual health information. We align with the principles of Universal Design and, as such, present design recommendations to inform the design of inclusive online sexual health interventions

Can Internet-Based Sexual Health Services Increase Diagnoses of Sexually Transmitted Infections (STI)? Protocol for a Randomized Evaluation of an Internet-Based STI Testing and Results Service.

BACKGROUND: Ensuring rapid access to high quality sexual health services is a key public health objective, both in the United Kingdom and internationally. Internet-based testing services for sexually transmitted infections (STIs) are considered to be a promising way to achieve this goal. This study will evaluate a nascent online STI testing and results service in South East London, delivered alongside standard face-to-face STI testing services. OBJECTIVE: The aim of this study is to establish whether an online testing and results services can (1) increase diagnoses of STIs and (2) increase uptake of STI testing, when delivered alongside standard face-to-face STI testing services. METHODS: This is a single-blind randomized controlled trial. We will recruit 3000 participants who meet the following eligibility criteria: 16-30 years of age, resident in the London boroughs of Lambeth and Southwark, having at least one sexual partner in the last 12 months, having access to the Internet and willing to take an STI test. People unable to provide informed consent and unable to read and understand English (the websites will be in English) will be excluded. Baseline data will be collected at enrolment. This includes participant contact details, demographic data (date of birth, gender, ethnicity, and sexual orientation), and sexual health behaviors (last STI test, service used at last STI test and number of sexual partners in the last 12 months). Once enrolled, participants will be randomly allocated either (1) to an online STI testing and results service (Sexual Health 24) offering postal self-administered STI kits for chlamydia, gonorrhoea, syphilis, and HIV; results via text message (short message service, SMS), except positive results for HIV, which will be delivered by phone; and direct referrals to local clinics for treatment or (2) to a conventional sexual health information website with signposting to local clinic-based sexual health services. Participants will be free to use any other interventions or services during the trial period. At 6 weeks from randomization we will collect self-reported follow-up data on service use, STI tests and results, treatment prescribed, and acceptability of STI testing services. We will also collect objective data from participating STI testing services on uptake of STI testing, STI diagnoses and treatment. We hypothesise that uptake of STI testing and STI diagnoses will be higher in the intervention arm. Our hypothesis is based on the assumption that the intervention is less time-consuming, more convenient, more private, and incur less stigma and embarrassment than face-to-face STI testing pathways. The primary outcome measure is diagnosis of any STI at 6 weeks from randomization and our co-primary outcome is completion of any STI test at 6 weeks from randomization. We define completion of a test, as samples returned, processed, and results delivered to the intervention and/or clinic settings. We will use risk ratios to calculate the effect of the intervention on our primary outcomes with 95% confidence intervals. All analyses will be based on the intention-to-treat (ITT) principle. RESULTS: This study is funded by Guy's and St Thomas' Charity and it has received ethical approval from NRES Committee London-Camberwell St Giles (Ref 14/LO/1477). Research and Development approval has been obtained from Kings College Hospital NHS Foundation Trust and Guy's and St Thomas' NHS Foundation Trust. Results are expected in June 2016. CONCLUSIONS: This study will provide evidence on the effectiveness of an online STI testing and results service in South East London. Our findings may also be generalizable to similar populations in the United Kingdom.

Remote self-testing for sexually transmitted infections, within online care pathways: how could this intervention deliver public health benefit? Formative research using chlamydia as an exemplar

Sexually transmitted infections (STIs) remain a public health challenge in England, despite free, confidential testing/treatment services. The eSTI² Research Consortium is developing a diagnostic self-test for STIs, to be deployed within online care-pathways. Should this intervention lead to increased STI detection and prompt effective treatment, it could reduce transmission and morbidity. Through a scoping review and three studies I explored its potential to benefit public health, thus informing the intervention’s ongoing development. The review (2013) found diverse uses of internet/electronic communications in STI care-pathways, but little research was transferable to remote self-testing or management. Current internet-use for sexual health may predict use of the proposed intervention, so I estimated its prevalence, and identified associated factors, using British probability survey data (2010-12). Among sexually-experienced 16-44-year-olds (n=8926), internet-use for STI testing/treatment was rare (<0.5%), but available services were limited. 4.5% women and 4.6% men reported internet-use for information/support with their sex-lives, elevated among the better-educated and some STI risk-groups including young people. In qualitative interviews, 25 young people at risk of STI expressed enthusiasm for a (hypothetical) STI self-test within online care-pathways. Findings informed colleagues’ development of eSTI²’s Online Chlamydia Pathway (OCP). For people requiring chlamydia treatment, this included: online automated medical assessment, a helpline, and community pharmacy treatment collection or facilitated clinic access. I undertook and thematically-analysed 40 qualitative interviews with OCP users, within pilot studies. Participants valued the rapid, convenient and discreet treatment access, increased control over their healthcare, and optional professional support by telephone, enabled by the OCP. Offline parts of the pathway (pharmacy/clinic attendance) risked compromising its perceived advantages, and require further development. Recommendations derived from an iteratively-developed understanding of this complex intervention’s use and appeal, can enhance its potential to enable STI detection and treatment, promptly, effectively and acceptably. Future evaluation must consider impacts on health inequalities

Developing eSexual Health within the NHS How can we optimally design, implement and evaluate an internet-based clinical pathway for remote testing, diagnosis, clinical assessment, antibiotic prescribing and partner management of sexually transmitted infections?

PhD (md res)Over the past 20 years, the incorporation of eHealth within health services in England has expanded organically in diverse ways, usually in response to local perceived need, interest or funding. UK government policy and strategies have taken an optimistic view of how eHealth can revolutionise publically funded health care provision and implementation lags far behind expectations. Although there are some excellent examples of how eHealth has been incorporated into NHS practice in a beneficial manner, there is also a concerning lack of evidence to support many of the interventions and new models of service delivery. This largely reflects a disparate and fragmented evidence base within current eHealth literature, particularly in relation to methods for developing online care pathways. This doctoral research is focused on developing and implementing an online automated clinical care pathway for people with genital chlamydia infection, and developing a robust framework for its evaluation. The care pathway is a core component of an eSexual Health Clinic, also developed as part of this work, which is fully integrated within an NHS specialist sexual health service. An online clinical pathway taking a person from diagnosis of a new condition, through an automated clinical consultation, partner notification and collection of antibiotics from a community pharmacy via an electronic prescription has never been done before in the UK. The novelty of the work and paucity of literature in this field at times necessitated a different approach from conventional research practice. I started by conducting a scoping review to identify the legal, regulatory, ethical and perceptual barriers to introducing such a pathway into the NHS. Electronic prescribing across the secondary and primary care interface stood out as a barrier to implementation. There was also a clear lack of evidence in terms of the content and accuracy of sexual health mobile medical applications. I went on to conduct detailed reviews of both of these areas. 3 In the absence of any relevant guidance on developing online clinical care pathways, I then developed my own methods, underpinned by evidence adapted from guidance aimed at traditional clinical care, existing protocols and practice, eHealth and sexual health literature and questionnaires, and created a new eClinical Care Pathway Framework. I then applied this framework to guide my development of the online clinical care pathway for people with genital chlamydia. We then needed to demonstrate that the Chlamydia online clinical care pathway was feasible, acceptable and safe to take forward into a large scale trial, and potentially implement into clinical practice. There are no accepted methods for evaluation of this type of online clinical care pathway and my final piece of work focussed on developing a set of evaluation techniques and activities, which would assess all these elements to determine whether the online pathway was fit for purpose. Outputs of this doctoral work include: a comprehensive review of contemporary sexually transmitted infection and sexual health mobile applications (apps); a comprehensive review of electronic prescribing in the UK; a method for developing complex online clinical care pathways based on a novel framework; UK’s first automated online clinical care pathway for people with genital chlamydia, and finally a method for evaluation of online clinical care pathways
