RESUMO

We developed the Achieving Self-directed Integrated Cancer Aftercare (ASICA) in melanoma app to support monthly total-skin self-examinations (TSSE) by people previously treated for melanoma. A randomized 12-month trial demonstrated ASICA supported optimal monthly TSSE adherence in a third of participants (ClinicalTrials.gov NCT03328247). However, a further third of participants adhered well initially but subsequently dropped off, and a final third did not adhere at all. This follow-up qualitative study investigated trial participants' perceptions of barriers and facilitators to TSSE adherence using the app. Three former trial participants participated in a single focus group and 11 participated in new semistructured telephone interviews. These were analysed thematically alongside secondary analysis of 13 qualitative interviews conducted during the trial. All transcripts were recorded, transcribed and analysed thematically. Five themes encompassing barriers and facilitators to ASICA adherence emerged. These were: technology, role of others, tailoring, disease journey and competing priorities. These data will inform further development of ASICA to increase user adherence.

RESUMO

BACKGROUND: A randomised trial of European Fans in Training (EuroFIT), a 12-week healthy lifestyle program delivered in 15 professional football clubs in the Netherlands, Norway, Portugal, and the United Kingdom, successfully increased physical activity and improved diet but did not reduce sedentary time. To guide future implementation, this paper investigates how those effects were achieved. We ask: 1) how was EuroFIT implemented? 2) what were the processes through which outcomes were achieved? METHODS: We analysed qualitative data implementation notes, observations of 29 of 180 weekly EuroFIT deliveries, semi-structured interviews with 16 coaches and 15 club representatives, and 30 focus group discussions with participants (15 post-program and 15 after 12 months). We descriptively analysed quantitative data on recruitment, attendance at sessions and logs of use of the technologies and survey data on the views of participants at baseline, post program and after 12 months. We used a triangulation protocol to investigate agreement between data from difference sources, organised around meeting 15 objectives within the two research questions. RESULTS: We successfully recruited clubs, coaches and men to EuroFIT though the draw of the football club seemed stronger in the UK and Portugal. Advertising that emphasized getting fitter, club-based deliveries, and not 'standing out' worked and attendance and fidelity were good, so that coaches in all countries were able to deliver EuroFIT flexibly as intended. Coaches in all 15 clubs facilitated the use of behaviour change techniques and interaction between men, which together enhanced motivation. Participants found it harder to change sedentary time than physical activity and diet. Fitting changes into daily routines, planning for setbacks and recognising the personal benefit of behaviour change were important to maintain changes. Bespoke technologies were valued, but technological hitches frustrated participants. CONCLUSION: EuroFIT was delivered as planned by trained club coaches working flexibly in all countries. It worked as expected to attract men and support initiation and maintenance of changes in physical activity and diet but the use of bespoke, unstable, technologies was frustrating. Future deliveries should eliminate the focus on sedentary time and should use only proven technologies to support self-monitoring and social interaction. TRIAL REGISTRATION: ISRCTN81935608, registered 16/06/2015.

RESUMO

BACKGROUND: Retention (participants completing a trial) is a persistent, and often under-studied, challenge within clinical trials. Research on retention has focussed on understanding the actions of participants who decide to remain or withdraw from trial participation and developing interventions to target improvements. To better understand how trial staff may influence participants to remain or withdraw from trials, it is important to explore the experiences of staff that recruit and retain said participants and how the process of recruitment impacts retention. METHODS: Two qualitative interview studies informed by the Theoretical Domains Framework (TDF) were conducted with staff involved in various stages of clinical trials. The first set of interviews were focussed on staff perceptions about why participants failed to be retained and what helped to keep others engaged in trials, but also explored more generally what strategies or factors contributed to retention in trials. The second set of interviews were focussed on staff perceptions specifically about the recruitment and informed consent process and how that may influence trial retention. All interviews were analysed using the TDF and assigned to relevant behavioural domains according to perceived barriers/facilitators of the target behaviour. Belief statements were generated, summarising the narrative content of related responses within these behavioural domains. These belief statements were further analysed for themes that captured higher order relationships between separate beliefs within and between behavioural domains. RESULTS: Twenty-five participants (9 retention staff and 16 recruitment staff) were interviewed. Themes describing the barriers/facilitators to retention broadly, and to communication of retention information at consent, were generated. Four themes on retention broadly and six themes on communication of retention information at consent were identified. Overall, beliefs within all fourteen TDF domains populated these themes. CONCLUSIONS: This study explored staff perspectives on retention and how they interpret their behaviour as contributing to retention success. Perspectives varied considerably but several key themes regarding communication were seen consistently. Specific barriers and facilitators within these findings will serve to guide the design of a behavioural intervention aimed at addressing issues within retention. Findings contribute to a notable gap in the literature on staff behaviour in trials and on retention generally.

RESUMO

BACKGROUND: The Scottish Government introduced a free Baby Box scheme for all new parents in 2017, modelled on the Finnish scheme, to give every baby 'an equal start in life'. There is little evidence that it results in better health outcomes, but there has been limited research into different perspectives and discourses on such schemes. METHODS: Four focus groups were conducted with 21 parents in North-East Scotland. Recordings were transcribed verbatim, anonymized and analysed thematically with NVivo 12 software. Our thematic analysis was both inductive and deductive-remaining open to themes identified by participants themselves but also informed by the social policy literature on universalism and social cohesion. RESULTS: Across all the focus groups, we found a high degree of positivity about the principle of the Baby Box scheme, and for the most part the practical value of the contents. This was remarkably consistent across different communities and backgrounds. There was little evidence of the strongly polarized views present in media reporting. Parents seemed considerably less focused than the media on safety and health outcomes, and more focused on practical, material and social impacts. They reported little in the way of feeling patronized or monitored by the government. CONCLUSION: Our findings have important implications for future economic evaluations of the baby box. Such evaluations should broaden the valuation space beyond health outcomes to allow for the value of feelings of inclusion, solidarity and being part of a community. PATIENT OR PUBLIC CONTRIBUTION: This small project was designed in response to parent views already collected in the early roll-out of the Baby Box scheme in Scotland, about their priorities and responses to the scheme. Additional views were sought on the topic guide for the focus groups, and local community groups advised us on recruitment and the best timing and location for the focus groups to be held. The focus groups themselves were conducted as research, but with the intent of ensuring parent views featured more prominently in a debate that has been largely dominated by clinical and public health perspectives.

RESUMO

BACKGROUND: Women use fertility tracking apps (FTAs) for conception purposes, but user perspectives on FTA use for conception are largely unknown. In collaboration with SPD Clearblue, this study explored: how women trying to conceive use FTAs; women's knowledge of their conception chances; and women's feelings towards a potential natural conception prediction app (NCPA). METHODS: A mixed methods design was used (online survey and phone interviews). Participants were women 18-40 years old actively trying to conceive. RESULTS: The survey received 154 responses and 24 interviews were conducted. Thematic analysis of interviews found that women consider several factors before trying to conceive (ex. age, financial and job security, stability of relationship, etc.) and may adopt lifestyle and behaviour changes when trying (ex. increasing exercise, smoking cessation, diet changes, etc.). Survey results indicated that nearly all respondents were aware of FTAs (n = 146, 94.8%), however, several other fertility and conception information sources were also used (ex. health care providers, online sources, family and friends, etc.). Nearly all respondents reported they would use an NCPA (n = 153, 99.4%). During interviews women had positive feelings towards such an app due to it offering new and individualised information, but worried the app could provide upsetting information. CONCLUSION: This research elaborates on women's uses of and interest in FTAs. Stakeholders should use this research to reflect on current conception experiences and possibilities for improvement through development of an NCPA. Future research should seek opinions from a more diverse sample of women to inform the development of an inclusive NCPA.

RESUMO

BACKGROUND: Understanding stakeholders' perceptions is crucial to the development and implementation of any intervention. However, a structured approach to eliciting stakeholder insights into complex, multisector issues of food security, household environment and health is lacking in many low and middle-income countries. This qualitative, workshop-based participatory study explores stakeholders' experiences of developing and implementing multisector interventions to provide transdisciplinary lessons for future developments in low and middle-income countries. METHODS: Participants were purposely selected based on their involvement in, or exposure to, the multisector intervention. Participants with interests in agriculture, nutrition, household air-quality, drinking water-quality and health from academic institutes, government and developmental organisations were brought together at a one-day workshop to participate in a series of discussions on issues relating to food security, nutrition, household environment and health in Nepal. All group discussions were audio-recorded and transcribed, and a thematic qualitative analysis performed to identify relevant themes. RESULTS: The government's ongoing Multisector Nutrition Plan, stakeholders' willingness to work together, availability of local infrastructure for cross-institutional inputs and increasing global movement towards transdisciplinary approaches were identified by the 33 workshop participants, representing 23 organisations as key factors determining success of transdisciplinary work. Fragmentation, lack of research-based and practice-based evidence, limited transdisciplinary knowledge amongst sectoral stakeholders, short-term funding and lack of knowledge-sharing mechanisms were identified as barriers, often creating systematic problems for successful implementation. Stakeholders suggested methods to bring about success included: improved knowledge, both amongst policy-makers and implementers, of food security and its linkage with nutrition, household environments, health and hygiene; investment in collaborative practice-based research and evidence-based practice; and strengthened transdisciplinary collaboration between multi-stakeholders, such as researchers, implementers and beneficiaries, throughout the intervention development and implementation process. CONCLUSIONS: This study suggests that multisector approach needs to adapt to take into account the experiences and views of the stakeholders concerned. The paper offers recommendations for successful development and implementation of future multisector interventions in Nepal that can be extrapolated to other low and middle-income countries, and lays foundations for future transdisciplinary working to support realisation of the recommendations.

RESUMO

PURPOSE: The National Cancer Institute has acknowledged that for children, adolescents and young adults (AYAs), cancer is a leading cause of disability and death. This population has unique needs and until we fully understand those needs, we will not be able to provide optimal care. The purpose of this study was to understand the self-reported experience of cancer according to children and AYAs. DESIGN AND METHODS: A qualitative descriptive design was used. After obtaining IRB approval, participants were interviewed in Spanish or English. Thirty interviews were conducted with children and AYAs ages 10-22. Questions were asked about the patient's treatment journey and the impact on their lifestyle. The interviews were recorded directly in digital audio files, then transcribed using Verbal Ink®. Themes were derived after the data were organized using Dedoose® and then coded. RESULTS: Children and AYAs described the cancer experience as difficult due to activity challenges and disconnection from school. Patients noted that their physical inactivity led to deconditioning. Children and AYAs reported storytelling as a way to cope with newfound disabilities. Patients reported that their illness allowed them to build closer relationships to family. Feelings on other issues arose, such as communication challenges experienced with transition from adult to pediatric hospitals. The value of altruism emerged as a way to provide purpose in their journey. CONCLUSIONS: Children and AYAs have particular concerns that the healthcare community needs to address. These qualitative findings have specific recommendations for practice.

RESUMO

A mild and operationally convenient formation of synthetically valuable N-sulfonyl imines from a range of aryl aldehydes by reaction with iminoiodinanes (PhI[double bond, length as m-dash]NZ) and I2 has been developed. According to mechanistic experiments described within, the reaction is speculated to proceed through an unconventional light-promoted, N-centered radical (NCR) pathway involving a N,N-diiodosulfonamide reactive species. This method not only provides a new pathway toward the production of activated imines, but also serves as an example of a non-traditional means of carbonyl activation via an NCR species.

RESUMO

BACKGROUND: Health policies internationally advocate 'support for self-management', but it is not clear how the promise of the concept can be fulfilled. OBJECTIVE: To synthesize research into professional practitioners' perspectives, practices and experiences to help inform a reconceptualization of support for self-management. DESIGN: Critical interpretive synthesis using systematic searches of literature published 2000-2014. FINDINGS: We summarized key insights from 164 relevant papers in an annotated bibliography. The literature illustrates striking variations in approaches to support for self-management and interpretations of associated concepts. We focused particularly on the somewhat neglected question of the purpose of support. We suggest that this can illuminate and explain important differences between narrower and broader approaches. Narrower approaches support people to manage their condition(s) well in terms of disease control. This purpose can underpin more hierarchical practitioner-patient communication and more limited views of patient empowerment. It is often associated with experiences of failure and frustration. Broader approaches support people to manage well with their condition(s). They can keep work on disease control in perspective as attention focuses on what matters to people and how they can be supported to shape their own lives. Broader approaches are currently less evident in practice. DISCUSSION AND CONCLUSION: Broader approaches seem necessary to fulfil the promise of support for self-management, especially for patient empowerment. A commitment to enable people to live well with long-term conditions could provide a coherent basis for the forms and outcomes of support that policies aspire to. The implications of such a commitment need further attention.

RESUMO

BACKGROUND: High-heeled shoes (high heels) are frequently worn by many women and form an important part of female gender identity. Issues of explicit and implicit compulsion to wear high heels have been noted. Previous studies and reviews have provided evidence that high heels are detrimental to health. However, the evidence base remains fragmented and no review has covered both the epidemiological and biomechanical literature. In addition, no review has considered the psychosexual benefits that offer essential context in understanding the public health challenge of high heels. METHODS: We searched seven major bibliographic databases up to November 2016, in addition to supplementary searches. We initially identified all review articles of any design that assessed either the psychosexual benefits or negative musculoskeletal health effects of high heels, the latter looking at both the epidemiological and biomechanical perspectives. We additionally considered additional primary studies on areas that had not been reviewed before or in which a marked lack of evidence had been noted. Data were extracted onto standardised forms. Proportionate second review was conducted. RESULTS: A total of 506 unique records were identified, 27 full-text publications were screened and 20 publications (7 reviews and 13 additional studies) were included in our evidence synthesis. The most up-to-date epidemiological review provides clear evidence of an association between high heel wear and hallux valgus, musculoskeletal pain and first-party injury. The body of biomechanical reviews provides clear evidence of changes indicative of increased risk of these outcomes, as well as osteoarthritis, which is not yet evidenced by epidemiological studies. There were no reviews on psychosexual benefits, but all five identified original studies provided evidence of increased attractiveness and/or an impact on men's behaviour associated with high heel wear. With regard to second-party injury, evidence is limited to one descriptive study and eight case reports. CONCLUSIONS: Our evidence synthesis clearly shows that high heels bring psychosexual benefits to women but are detrimental to their health. In light of this dilemma, it is important that women's freedom of choice is respected and that any remaining issues of explicit or implicit compulsion are addressed.

RESUMO

BACKGROUND: Support for self-management (SSM) is a prominent strand of health policy internationally, particularly for primary care. It is often discussed and evaluated in terms of patients' knowledge, skills and confidence, health-related behaviours, disease control or risk reduction, and service use and costs. However, these goals are limited, both as guides to professional practice and as indicators of its quality. In order to better understand what it means to support self-management well, we examined health professionals' views of success in their work with people with long-term conditions. This study formed part of a broader project to develop a conceptual account of SSM that can reflect and promote good practice. METHODS: Semi-structured individual interviews (n = 26) and subsequent group discussions (n = 5 groups, 30 participants) with diverse health professionals working with people with diabetes and/or Parkinson's disease in NHS services in London, northern England or Scotland. The interviews explored examples of more and less successful work, ways of defining success, and ideas about what facilitates success in practice. Subsequent group discussions considered the practical implications of different accounts of SSM. Interviews and group discussions were audio-recorded, transcribed and analysed thematically. RESULTS: Participants identified a wide range of interlinked aspects or elements of success relating to: health, wellbeing and quality of life; how well people (can) manage; and professional-patient relationships. They also mentioned a number of considerations that have important implications for assessing the quality of their own performance. These considerations in part reflect variations in what matters and what is realistically achievable for particular people, in particular situations and at particular times, as well as the complexity of questions of attribution. CONCLUSIONS: A nuanced assessment of the quality of support for self-management requires attention to the responsiveness of professional practice to a wide, complex range of personal and situational states, as well as actions and interactions over time. A narrow focus on particular indicators can lead to insensitive or even perverse judgements and perhaps counterproductive effects. More open, critical discussions about both success and the assessment of quality are needed to facilitate good professional practice and service improvement initiatives.

RESUMO

A mild and operationally convenient amino-functionalization of a range of tertiary alkyl halides by reaction with iminoiodinanes (PhI[double bond, length as m-dash]NNs) and I2 has been developed. According to the mechanistic experiments described within, the reaction is speculated to proceed through a light-promoted, N-centered radical pathway involving a N,N-diiodosulfonamide reactive species. This method of direct N-incorporation offers an attractive alternative to the production of α-tertiary amines, a synthetically challenging structural class found in a variety of bioactive molecules.

RESUMO

BACKGROUND: Maternal smoking can cause health complications in pregnancy. Particulate matter (PM2.5) metrics applied to second hand smoke (SHS) concentrations provide indoor air quality (IAQ) measurements and have been used to promote smoking behaviour change among parents of young children. Here, we present the qualitative results from a study designed to use IAQ measurements to help pregnant women who smoke to quit smoking. METHODS: We used IAQ measurements in two centres (Aberdeen and Coventry) using two interventions: 1. In Aberdeen, women made IAQ measurements in their homes following routine ultrasound scan; 2. In Coventry, IAQ measurements were added to a home-based Stop Smoking in Pregnancy Service. All women were invited to give a qualitative interview to explore acceptability and feasibility of IAQ measurements to help with smoking cessation. A case study approach using grounded theory was applied to develop a typology of pregnant women who smoke. RESULTS: There were 39 women recruited (18 in Aberdeen and 21 in Coventry) and qualitative interviews were undertaken with nine of those women. Diverse accounts of smoking behaviours and experiences of participation were given. Many women reported changes to their smoking behaviours during pregnancy. Most women wanted to make further changes to their own behaviour, but could not commit or felt constrained by living with a partner or family members who smoked. Others could not envisage quitting. Using themes emerging from the interviews, we constructed a typology where women were classified as follows: 'champions for change'; 'keen, but not committed'; and 'can't quit, won't quit'. Three women reported quitting smoking alongside participation in our study. CONCLUSIONS: Pregnant women who smoke remain hard to engage,. Although providing IAQ measurements does not obviously improve quit rates, it can support changes in smoking behaviour in/around the home for some individuals. Our typology might offer a useful assessment tool for midwives.

RESUMO

Increasing breastfeeding rates would improve maternal and child health, but multiple barriers to breastfeeding persist. Breast pump provision has been used as an incentive for breastfeeding, although effectiveness is unclear. Women's use of breast pumps is increasing and a high proportion of mothers express breastmilk. No research has yet reported women's and health professionals' perspectives on breast pumps as an incentive for breastfeeding. In the Benefits of Incentives for Breastfeeding and Smoking cessation in pregnancy (BIBS) study, mixed methods research explored women's and professionals' views of breast pumps as an incentive for breastfeeding. A survey of health professionals across Scotland and North West England measured agreement with 'a breast pump costing around £40 provided for free on the NHS' as an incentive strategy. Qualitative interviews and focus groups were conducted in two UK regions with a total of 68 participants (pregnant women, new mothers, and their significant others and health professionals) and thematic analysis undertaken. The survey of 497 health professionals found net agreement of 67.8% (337/497) with the breast pump incentive strategy, with no predictors of agreement shown by a multiple ordered logistic regression model. Qualitative research found interrelated themes of the 'appeal and value of breast pumps', 'sharing the load', 'perceived benefits', 'perceived risks' and issues related to 'timing'. Qualitative participants expressed mixed views on the acceptability of breast pumps as an incentive for breastfeeding. Understanding the mechanisms of action for pump type, timing and additional support required for effectiveness is required to underpin trials of breast pump provision as an incentive for improving breastfeeding outcomes. © 2016 The Authors.

RESUMO

Reveromycin A (RM-A), a small natural product isolated from Streptomyces bacteria, is a potential osteoporosis therapeutic in that it specifically induces apoptosis in osteoclasts but not osteoblasts. The purpose of the study presented here was to further elucidate the intracellular mechanisms of RM-A death effects in mature osteoclasts. A specific clone of RAW264.7 murine macrophages that was previously characterized for its ability to acquire an osteoclast nature on differentiation was differentiated in the presence of receptor activator of nuclear factor kappa B ligand (RANKL). Subsequent staining was performed for tartrate-resistant acid phosphatase to confirm their osteoclast character. These osteoclasts were treated with ten micromolar RM-A for 2, 4, 6, 24, and 48 h at a pH of 5.5. Peak apoptosis induction occurred at 4-6 h as measured by caspase 3 activity. Lactate dehydrogenase release assay revealed no significant RM-A-induced necrosis. Western blot analysis of cytoplasmic extracts demonstrated activation of caspase 9 (2.3-fold at 2 h and 2.6-fold at 4 h, each P < 0.05) and no significant changes in Bcl-XL . In nuclear extracts, NFκB levels significantly increased on differentiation with RANKL but then remained constant through RM-A treatment. Over the extended time course studied, RM-A-induced apoptosis in osteoclasts was not accompanied by necrosis, suggesting that RM-A would likely have limited effects on immediate, neighboring bone cell types. This specific cell death profile is promising for potential clinical investigations of RM-A as a bone antiresorptive.

RESUMO

Vision loss has been associated with mental health problems such as depression, anxiety, and post-traumatic stress disorder, which significantly impact lives of working age adults with adventitious total bilateral blindness and low vision. It is imperative, therefore, to prioritize the mental health in this population by exploring and understanding the factors that impact on their mental health. Hence, the objective of this scoping review is to identify and chart existing literature on the protective and risk factors of mental health of working age adults with adventitious total bilateral blindness and low vision. We developed this scoping review protocol in line with the Joanna Briggs Institute guidance. This scoping review will include publications in English language with no date restrictions exploring the protective and risk factors of mental health of our study population. A three-step search strategy will be employed. Searches will be carried out in the following databases: Medline, Embase, PsycInfo, PsycArticles, CINAHL and Web of Science. Search for grey literature will be conducted in Google, Google Scholar and Websites dedicated to information on visual impairment. Collated results will be imported into Endnote Basic (Clarivate) for deduplication. Two reviewers will independently conduct double screening of all the titles and abstracts in Rayyan- a web application, and full texts in Endnote while three other reviewers will conduct screening of a subset of for example 10% of titles and abstracts and full texts. Furthermore, two reviewers will independently conduct double data extraction while three other reviewers will revise, cross check, and correct any extraction errors. Extracted data will be presented in tabular formats and summarized descriptively in line with the research objectives. This scoping review will generate evidence on factors impacting the mental health of the working age adults with adventitious total bilateral blindness and low vision as well as critically highlight gaps in the literature. The findings will inform and critically underpin future empirical research which will explore the lived experiences of working age people with adventitious total bilateral blindness. Additionally, evidence from this review will inform the development of interventions in the promotion of mental health as well as assisting rehabilitation specialists and workers, public health practitioners and other relevant stakeholders in addressing the mental health needs of working age adults with adventitious total bilateral blindness and low vision.

RESUMO

BACKGROUND: Clinical trials are essential to evidence-based medicine. Their success relies on recruitment and retention of participants: problems with either can affect validity of results. Past research on improving trials has focused on recruitment, with less on retention, and even less considering retention at the point of recruitment, i.e., what retention-relevant information is shared during consent processes. The behaviour of trial staff communicating this information during consent is likely to contribute to retention. So, developing approaches to mitigate issues in retention at the point of consent is necessary. In this study, we describe the development of a behavioural intervention targeting the communication of information important to retention during the consent process. METHODS: We applied the Theoretical Domains Framework and Behaviour Change Wheel to develop an intervention aimed at changing the retention communication behaviours of trial staff. Building on findings from an interview study to understand the barriers/facilitators to retention communication during consent, we identified behaviour change techniques that could moderate them. These techniques were grouped into potential intervention categories and presented to a co-design group of trial staff and public partners to discuss how they might be packaged into an intervention. An intervention was presented to these same stakeholders and assessed for acceptability through a survey based on the Theoretical Framework of Acceptability. RESULTS: Twenty-six behaviour change techniques were identified with potential to change communication of retention-information at consent. Six trial stakeholders in the co-design group discussed means for implementing these techniques and agreed the available techniques could be most effective within a series of meetings focussed on best practices for communicating retention at consent. The proposed intervention was deemed acceptable through survey results. CONCLUSION: We have developed an intervention aimed at facilitating the communication of retention at informed consent through a behavioural approach. This intervention will be delivered to trial staff and will add to the available strategies for trials to improve retention.

RESUMO

BACKGROUND: Healthcare technologies are becoming more commonplace, however clinical and patient perspectives regarding the use of technology in the management of childhood asthma have yet to be investigated. Within a clinical trial of asthma management in children, we conducted a qualitative process evaluation that provided insights into the experiences and perspectives of healthcare staff and families on (i) the use of smart inhalers to monitor medication adherence and (ii) the use of algorithm generated treatment recommendations. METHODS: We interviewed trial staff (n = 15) and families (n = 6) who were involved in the trial to gauge perspectives around the use of smart inhalers to monitor adherence and the algorithm to guide clinical decision making. FINDINGS: Staff and families indicated that there were technical issues associated with the smart inhalers. While staff suggested that the smart inhalers were good for monitoring adherence and enabling communication regarding medication use, parents and children indicated that smart inhaler use increased motivation to adhere to medication and provided the patient (child) with a sense of responsibility for the management of their asthma. Staff were open-minded about the use of the algorithm to guide treatment recommendations, but some were not familiar with its' use in clinical care. There were some concerns expressed regarding treatment step-down decisions generated by the algorithm, and some staff highlighted the importance of using clinical judgement. Families perceived the algorithm to be a useful technology, but indicated that they felt comforted by the clinicians' own judgements. CONCLUSION: The use of technology and individual data within appointments was considered useful to both staff and families: closer monitoring and the educational impacts were especially highlighted. Utilising an algorithm was broadly acceptable, with caveats around clinicians using the recommendations as a guide only and wariness around extreme step-ups/downs considering contextual factors not taken into account.

RESUMO

BACKGROUND: Melanoma is a relatively common cancer type with a high survival rate, but survivors risk recurrences or second primaries. Consequently, patients receive regular hospital follow-up, but this can be burdensome to attend and not optimally timed to detect arising problems. Total skin self-examination (TSSE) supports improved clinical outcomes from melanoma via earlier detection of recurrences and second primaries, and digital technology has the potential to support TSSE. Recent research with app-based interventions aimed at improving the well-being of older adults has found that they can use the technology and benefit from it, supporting the use of digital health care in diverse demographic groups. Thus, the Achieving Self-directed Integrated Cancer Aftercare (ASICA) digital health care intervention was developed. The intervention provided melanoma survivors with a monthly prompt to perform a TSSE as well as access to a dermatology nurse who provided them with feedback on photographs and descriptions of their skin. OBJECTIVE: We aimed to explore participants' attitudes, beliefs, and experiences regarding TSSE practices. Furthermore, we explored how participants experienced technology and how it influenced their practice of TSSE. Finally, we explored the practical and technical experiences of ASICA users. METHODS: This was a nested qualitative evaluation within a dual-center randomized controlled trial of the ASICA intervention. We conducted semistructured telephone interviews with the participants during a randomized controlled trial. The participants were purposively sampled to achieve a representative sample with representative proportions by age, sex, and residential geography. Interviews were transcribed verbatim and analyzed using a framework analysis approach applied within NVivo 12. RESULTS: A total of 22 interviews were conducted with participants from both groups. In total, 40% (9/22) of the interviewed participants were from rural areas, and 60% (13/22) were from urban areas; 60% (13/22) were from the intervention group, and 40% (9/22) were from the control group. Themes evolved around skin-checking behavior, other people's input into skin checking, contribution of health care professionals outside ASICA and its value, ideas around technology, practical experiences, and potential improvements. ASICA appeared to change participants' perceptions of skin checking. Users were more likely to report routinely performing TSSE thoroughly. There was some variation in beliefs about skin checking and using technology for health care. Overall, ASICA was experienced positively by participants. Several practical suggestions were made for the improvement of ASICA. CONCLUSIONS: The ASICA intervention appeared to have positively influenced the attitudes and TSSE practices of melanoma survivors. This study provides important qualitative information about how a digital health care intervention is an effective means of prompting, recording, and responding to structured TSSE by melanoma survivors. Technical improvements are required, but the app offers promise for technologically enhanced melanoma follow-up in future.
