Guided versus non-guided digital psychological interventions for cancer patients: A systematic review and meta-analysis of engagement and efficacy.

OBJECTIVE: To evaluate engagement with and efficacy of guided versus non-guided digital interventions targeting psychological symptoms of cancer via a systematic review of current evidence. METHODS: PubMed, Scopus, PsychINFO, MEDLINE, and CINAHL databases were searched. Eligible publications were randomised controlled trials of guided or non-guided digital psychological interventions used in cancer settings reporting intervention efficacy and/or engagement. Study methodological quality was assessed using the Cochrane risk of bias (RoB) tool. Random effects meta-analyses were performed on outcomes with sufficient data, with sub-group analyses of intervention type and follow-up period. RESULTS: Forty-three studies were included. Studies varied by level of guidance, type of technology used, duration, and outcomes assessed. Most studies had a high overall RoB. Meta-analysis indicated that guided interventions significantly reduced distress, anxiety, and fatigue, while non-guided did not. For depression and quality of life, both guided and non-guided interventions produced significant improvements. Guided interventions reported higher levels of intervention engagement than non-guided. CONCLUSIONS: Guided digital psychological interventions were likely to be more effective than non-guided ones for cancer patients, particularly in reducing distress, anxiety, and fatigue. Whilst both types were found to improve depression and life quality, guided interventions were associated with higher patient engagement. These findings suggest digital interventions could supplement traditional cancer care, warranting further research concerning long-term effects and cost-efficiency.

How Are Clinicians' Acceptance and Use of Clinical Decision Support Systems Evaluated Over Time? A Systematic Review.

Clinical decision support systems (CDSS) can enhance the safety and quality of patient care, but their benefits are often hampered by low acceptance and use by clinicians in practice. Existing research has explored clinicians' experiences with CDSS in a static nature, with limited consideration of how user needs may change over time. This review aimed to identify the methods used to capture clinicians' acceptance and use of CDSS in hospital settings at different time points following implementation and highlight gaps to inform future work. Seventy-six studies met inclusion criteria. Qualitative methods were rarely used during the early implementation phases, particularly in the first 2 months following implementation. Further work is needed to understand clinicians' experiences immediately following implementation of CDSS and how these insights can be used to support use over time.

Fighting the Same Battles on a New Battleground: Embedding Technologies in a Virtual Care Environment.

The pandemic necessitated the rapid design, development and implementation of technologies to allow remote monitoring of COVID-19 patients at home. This study aimed to explore the environmental barriers and facilitators to the successful development and implementation of virtual care technologies in this fast-paced context. We interviewed eight staff at a virtual hospital in Australia. We found key facilitators to be a learning organizational culture and strong leadership support. Barriers included interoperability issues, legislative constraints and unrealistic clinician expectations. Also, we found that a combination of hot-desking and the lack of single sign on in the virtual care environment, was reported to create additional work for staff. Overall, despite this unique context, our findings are consistent with prior work examining design and implementation of healthcare technologies. The fast pace and high-pressure environment appeared to magnify previously reported barriers, but also cultivate and foster a learning culture.

Clinical decision support systems for chronic obstructive pulmonary disease (COPD) in hospitals: A systematic review.

Objectives: To synthesise the literature on clinical decision support (CDS) systems for chronic obstructive pulmonary disease (COPD). We aimed to (1) describe existing COPD CDS systems that have been designed, developed or are being used in practice, (2) describe the impact of COPD CDS systems on outcomes and (3) identify barriers and facilitators to implementation of COPD CDS systems. Methods: Five databases were searched to identify relevant studies. All studies in English that described clinician-facing COPD CDS systems designed for, or implemented in, hospitals and hospital-in-the-home settings were included. A qualitative narrative synthesis was undertaken, guided by the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation and Maintenance). Results: Twelve studies reporting the use of CDS in hospital (n = 7) and hospital-in-the-home (n = 5) settings were included. Implementation efforts to reach target users were scantly reported, and low-to-medium adoption rates were observed. The reported effectiveness of the CDS systems was mixed. Only one study reported facilitators to the implementation of CDS systems, none reported on barriers to the implementation of CDS systems, and none reported any information on successful strategies to maintain implementation of CDS systems. Conclusion: The use of CDS systems in the management of patients with COPD in hospital-related settings is an important emerging field of research. Evidence suggests that the field has largely focused on systems targeted at physicians, often with incomplete descriptions and limited evaluations. Many opportunities to optimise and evaluate the implementation and use of COPD CDS systems in hospital settings remain, including robust evaluation of their impact on patient, clinician and health service outcomes.

How digital health translational research is prioritised: a qualitative stakeholder-driven approach to decision support evaluation.

OBJECTIVES: Digital health is now routinely being applied in clinical care, and with a variety of clinician-facing systems available, healthcare organisations are increasingly required to make decisions about technology implementation and evaluation. However, few studies have examined how digital health research is prioritised, particularly research focused on clinician-facing decision support systems. This study aimed to identify criteria for prioritising digital health research, examine how these differ from criteria for prioritising traditional health research and determine priority decision support use cases for a collaborative implementation research programme. METHODS: Drawing on an interpretive listening model for priority setting and a stakeholder-driven approach, our prioritisation process involved stakeholder identification, eliciting decision support use case priorities from stakeholders, generating initial use case priorities and finalising preferred use cases based on consultations. In this qualitative study, online focus group session(s) were held with stakeholders, audiorecorded, transcribed and analysed thematically. RESULTS: Fifteen participants attended the online priority setting sessions. Criteria for prioritising digital health research fell into three themes, namely: public health benefit, health system-level factors and research process and feasibility. We identified criteria unique to digital health research as the availability of suitable governance frameworks, candidate technology's alignment with other technologies in use,and the possibility of data-driven insights from health technology data. The final selected use cases were remote monitoring of patients with pulmonary conditions, sepsis detection and automated breast screening. CONCLUSION: The criteria for determining digital health research priority areas are more nuanced than that of traditional health condition focused research and can neither be viewed solely through a clinical lens nor technological lens. As digital health research relies heavily on health technology implementation, digital health prioritisation criteria comprised enablers of successful technology implementation. Our prioritisation process could be applied to other settings and collaborative projects where research institutions partner with healthcare delivery organisations.

Does Involving Clinicians in Decision Support Development Facilitate System Use Over Time? A Systematic Review.

Involving clinician users in the design and development of Clinical Decision Support (CDS) systems is touted to improve the fit between system and user needs. However, the impact of clinician involvement on CDS acceptance and use in practice has not been systematically studied. This review aimed to identify the approaches taken to involve clinicians in CDS development and understand the impact of these approaches on barriers and facilitators to acceptance and use in hospital settings over time. Twenty-three studies met full inclusion criteria. Clinician involvement was rarely described in depth and no comparative studies were identified. Despite frequently reporting perceived ease of use, included studies still reported barriers to acceptance and use shortly after CDS implementation and years later. Future studies should report clinician involvement in adequate detail to enable understanding of its impact on CDS acceptance and use over time. Additional recommendations for future research, including conducting comparative studies and maintaining clinician involvement beyond implementation, are described.

Evaluation of the validity and screening performance of a revised single-item fear of cancer recurrence screening measure (FCR-1r).

OBJECTIVE: Fear of cancer recurrence (FCR) is highly prevalent among cancer survivors, but irregularly identified in practice. Single-item FCR measures suitable for integration into broader psychosocial screening are needed. This study evaluated the validity of a revised version of the original FCR-1 (FCR-1r) and screening performance alongside the Edmonton Symptom Assessment System - Revised (ESAS-r) anxiety item. METHODS: The FCR-1r was adapted from the FCR-1 and modelled on the ESAS-r. Associations between FCR-1r and FCR Inventory-Short Form (FCRI-SF) scores determined concurrent validity. Relationships of FCR-1r scores with variables related (e.g., anxiety, intrusive thoughts) and unrelated (e.g., employment/marital status) to FCR determined convergent and divergent validity respectively. A Receiver-Operating Characteristic analysis examined screening performance and cut-offs for the FCR-1r and ESAS-r anxiety item. RESULTS: 107 participants were recruited in two studies (Study 1, July-October 2021, n = 54; Study 2: November 2021-May 2022, n = 53). The FCR-1r demonstrated concurrent validity against the FCRI-SF (r = 0.83, p < 0.0001) and convergent validity versus the Generalised Anxiety Disorder-7 (r = 0.63, p < 0.0001) and Impact of Event Scale-Revised Intrusion subscale (r = 0.55, p < 0.0001). It did not correlate with unrelated variables (e.g., employment/marital status), indicating divergent validity. An FCR-1r cut-off ≥5/10 had 95% sensitivity and 77% specificity for detecting clinical FCR (area under the curve (AUC) = 0.91, 95% CI 0.85-0.97, p < 0.0001); ESAS-r anxiety cut-off ≥4 had 91% sensitivity and 82% specificity (AUC = 0.87, 95% CI 0.77-0.98, p < 0.0001). CONCLUSIONS: The FCR-1r is a valid and accurate tool for FCR screening. Further evaluation of the screening performance of the FCR-1r versus the ESAS-r anxiety item in routine care is needed.

Cancer Care Team's Management of Clinical Alerts Generated by Electronically Collected Patient Reported Outcomes: We Could Do Better.

Electronically administered patient-reported outcome measures (ePROMs) are effective digital health tools for informing clinicians about cancer patients' symptoms and facilitating timely patient-centred care. This paper describes the delivery of healthcare activities supported by the PROMPT-Care model, including ePROMs generated clinical alerts, cancer care team (CCT) response to alerts, and patients' perceptions of the CCT response and ePROMs system. This mixed-methods study includes cancer patients from four cancer therapy centres in New South Wales, Australia. Quantitative and qualitative data were collected regarding clinical alert activity, CCT response, and patient perceptions of the CCT responses and ePROMs system. Qualitative data were thematically analysed. Of the 328 participants whose care was informed by the digital health tool, 70.8% (n = 233) generated at least one alert during the trial period, with 877 alerts generated in total. Although 43.7% (n = 383) were actioned by the CCT, at least 80% of participants found follow-up CCT phone calls beneficial, with multiple benefits confirmed in interviews. The cancer care delivery arm of the PROMPT-Care trial involving clinical alerts to the CCT was positively perceived by most participants, resulting in a diverse range of benefits. However, further work is required, informed by implementation science, to improve the percentage of actioned clinical alerts.

The Evaluation of the Suitability, Quality, and Readability of Publicly Available Online Resources for the Self-Management of Fear of Cancer Recurrence.

Cancer survivors often rely on the internet for health information, which has varying levels of readability, suitability, and quality. There is a need for high-quality online self-management resources for cancer survivors with fear of cancer recurrence (FCR). This study evaluated the readability, suitability, and quality of publicly available online FCR self-management resources. A Google search using FCR-related keywords identified freely available FCR self-management resources for cancer survivors in English. Resource readability (reading grade level), suitability, and quality were evaluated using relevant assessment tools. Descriptive statistics and cluster analysis identified resources with higher suitability and quality scores. Mean resource (n = 23) readability score was grade 11 (SD = 1.6, Range = 9-14). The mean suitability score was 56.0% (SD = 11.4%, Range = 31.0-76.3%), indicating average suitability and the mean quality score was 53% (SD = 11.7%, Range = 27-80%), indicating fair quality. A cluster of 15 (65%) resources with higher suitability and quality scores was identified. There were no significant associations between suitability or quality scores and the type of organisation that published the resources. Online FCR self-management resources varied in readability, suitability and quality. Resources with higher quality and suitability scores relative to other resources are identified for use by healthcare professionals and cancer survivors. Resources that are more culturally appropriate, with lower reading grade levels and detailed self-management strategies are needed.

Feasibility and preliminary efficacy of iConquerFear: a self-guided digital intervention for fear of cancer recurrence.

PURPOSE: Approximately 50% of cancer survivors experience moderate-severe fear of cancer recurrence (FCR). Self-guided digital interventions have potential to address the high level of FCR-related unmet needs at scale, but existing digital interventions have demonstrated variable engagement and efficacy. This study aimed to evaluate the feasibility and preliminary efficacy of iConquerFear, a five-module self-guided digital FCR intervention. METHODS: Eligible curatively treated breast cancer survivors were recruited. Participants reporting clinically significant FCR (≥ 13 on the Fear of Cancer Recurrence Inventory-Short Form; FCRI-SF) were given access to iConquerFear. Feasibility was indicated by > 50% of eligible participants enrolling in iConquerFear and recording moderate (≥ 120 min) or greater usage. Preliminary efficacy was evaluated via changes in self-reported FCR severity, anxiety, depression, intrusions and metacognitions from baseline to immediately and 3 months post-intervention. RESULTS: Fifty-four (83%) of 65 eligible participants enrolled in iConquerFear; six subsequently withdrew. Thirty-nine (83%) participants recorded moderate (n = 24; 120-599 min) or high (n = 15; ≥ 600 min) usage. Engagement levels increased with participant age (p = 0.043), but were lower in participants with higher baseline FCR (p = 0.028). Qualitative feedback indicated engagement was sometimes limited by difficulties with navigation and relating to featured survivors. Participants reported significantly improved FCR (mean reduction (95%CI): baseline to post-intervention - 3.44 (- 5.18, - 1.71), baseline to 3-month follow-up - 4.52 (- 6.25, - 2.78), p = < 0.001). CONCLUSION: iConquerFear is a feasible and potentially efficacious intervention for reducing FCR in breast cancer survivors. Easier navigation and more relatable examples may enhance engagement. IMPLICATIONS FOR CANCER SURVIVORS: iConquerFear may help address moderate but burdensome FCR levels in cancer survivors.

Stepping into the real world: a mixed-methods evaluation of the implementation of electronic patient reported outcomes in routine lung cancer care.

BACKGROUND: To realize the broader benefits of electronic patient-reported outcome measures (ePROMs) in routine care, we used the RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework to inform the translation of a clinically effective ePROM system (hereafter referred to as the PRM system) into practice. The study aimed to evaluate the processes and success of implementing the PRM system in the routine care of patients diagnosed with lung cancer. METHOD: A controlled before-and-after mixed-methods study was undertaken. Data sources included a self-report questionnaire and interviews with healthcare providers, electronic health record data for PRMs patients and historical controls, and field notes. Descriptive statistics, logistic regression modelling, negative binomial models, generalized estimating equations and repeated measures ANOVA were used to analyze quantitative data. Qualitative data was thematically analyzed. RESULTS: A total of 48/79 eligible people diagnosed with lung cancer completed 90 assessments during the 5-month implementation period (RE-AIM reach). Every assessment breached the pre-defined threshold and care coordinators reviewed and actioned 95.6% of breaches, resulting in 146 referrals to allied health services, most frequently for social work (25.3%), dietetics (18.5%), physiotherapy (18.5%) and occupational therapy (17.1%). PRMs patients had significantly fewer visits to the cancer assessment unit for problematic symptoms (M = 0.23 vs. M = 0.43; p = 0.035), and were significantly more likely to be offered referrals (71% vs. 29%, p < 0.0001) than historical controls (RE-AIM effect). The levels of 'organizational readiness for implementing change' (ORIC) did not show much differences between baseline and follow-up, though this was already high at baseline; but significantly more staff reported improved confidence when asking patients to complete assessments (64.7% at baseline vs. 88.2% at follow-up, p = 0.0046), and when describing the assessment tool to patients (64.7% at baseline vs. 76.47% at follow-up, p = 0.0018) (RE-AIM adoption). A total of 78 staff received PRM system training, and 95.6% of the PRM system alerts were actioned (RE-AIM implementation); and all lung cancer care coordinators were engaged with the PRM system beyond the end of the study period (RE-AIM maintenance). CONCLUSION: This study demonstrates the potential of the PRM system in enhancing the routine care of lung cancer patients, through leveraging the capabilities of automated web-based care options. Research has shown the clear benefits of using electronically collected patient-reported outcome measures (ePROMs) for cancer patients and health services. However, we need to better understand how to implement ePROMs as part of routine care. This study evaluated the processes and outcomes of implementing an ePROMs system in the routine care of patients diagnosed with lung cancer. Key findings included: (a) a majority of eligible patients completed the scheduled assessments; (b) patient concerns were identified in every assessment, and care coordinators reviewed and actioned almost all of these, including making significantly more referrals to allied health services; (c) patients completing assessments regularly were less likely to present to the cancer assessment unit with problematic symptoms, suggesting that ePROMs identified patient concerns early and this led to a timely response to concerns; (d) staff training and engagement was high, and staff reporting increased confidence when asking patients to complete assessments and when describing the assessment tool to patients at the end of the implementation period. This study shows that implementing ePROMs in routine care is feasible and can lead to improvements in patient care.

Implementing patient-reported outcomes into routine care: an audit of cancer patients from two local health districts in New South Wales to understand their capabilities and preferences.

Objective It has been established that the implementation of patient-reported outcome measures (PROMs) in routine care provides significant benefits to patients, providers and health services. However, there are patient-level barriers that must be identified and addressed for the successful implementation of PROMs. This study aimed to understand the capabilities and preferences of our cancer patient population prior to implementation of electronically collected PROMs (ePROMs). Specifically, we conducted a clinic audit to determine the proportion of patients in clinics with access to out-of-clinic internet; those preferring to complete PROMs on paper or via an electronic device; those capable of completing PROMs in English; and those anticipating requiring assistance to complete PROMs. Methods Patients receiving cancer treatment or follow-up care at two Local Health Districts (LHDs) in New South Wales, Australia, completed a questionnaire (audit form) with items about internet and mobile access, communication preferences and assistance needed to complete PROMs. Participant demographic and treatment information were extracted from their electronic medical records. Results Across both LHDs, 637 of 1668 participants (38%) completed the audit forms. Mean participant age was 65 years (range = 23-98), 53% were female, and 92% were outpatients. Patients in the two LHDs differed in their levels of internet and email access, and ability to complete PROMs independently in English, suggesting that some LHD-specific tailoring of implementation strategies is necessary to optimise ePROMs uptake. Conclusion This study highlights the importance of understanding the specific local contexts and patient populations, including potential technology and language barriers, which can influence patient ability to complete ePROMs.

A Delphi-based approach to developing the contents of an online resource, Care Assist, for male caregivers of women with breast cancer.

OBJECTIVE: Informal male caregivers of women with breast cancer (BC) have significant psychological, emotional, and social burdens that are inadequately addressed by current face-to-face interventions. Online interventions overcome barriers that limit engagement with face-to-face interventions. This study aimed to develop the contents of Care Assist, an online supportive care resource for male caregivers of BC patients, through expert consensus. METHODS: A Delphi study comprising two survey rounds and an expert consultation was conducted. In Round 1, experts in BC care rated the importance of 25 content items. In Round 2, they re-rated content items that failed to reach consensus (i.e. 80% agreement) in Round 1 or were newly developed. Free-text responses were also collected. During expert consultation, the resource was reviewed and revised for clarity. Iterative refinement followed all rounds. Quantitative data was analysed descriptively, and qualitative data was analysed using content analysis. RESULTS: Twenty-two experts participated and reached consensus on 96% of items, with 217 comments provided on: (a) the perceived benefits of Care Assist to caregivers and care recipients, (b) recommendations of newly suggested content items, wording, and use of external links, and (c) concerns regarding information overload and need for tailoring. The expert consultation comments focused on clarifying scope, wording, and information tailoring. CONCLUSION: The rigorous Delphi process resulted in the content for a comprehensive online supportive care intervention for male caregivers. Information overload can be minimised through self-identification of needs and utilisation of eHealth to personalise the resource for the heterogeneous male caregiver population.

Adapting an integrated care pathway for implementing electronic patient reported outcomes assessment in routine oncology care: Lessons learned from a case study.

RATIONALE, AIMS AND OBJECTIVE: Details of the development and implementation of integrated care pathways (ICPs) in the context of electronic collection of patient reported outcomes (ePROs) for cancer patients are largely lacking in the literature. This study describes what, why and how decisions were made to adapt and implement an ePROs ICP for patients with lung cancer. METHODS: A consensus process was utilized, with the implementation advisory group including multidisciplinary representation from three participating hospitals, to identify local champions and adapt and incorporate the ePRO ICP into the local contexts. Engagement meetings were documented via meeting transcripts, and detailed notes from October 2019 to November 2020 were content-analysed to identify decision-making themes based on the Consolidated Framework for Implementation Research; workflows and process maps were reviewed and modified to integrate ePROs. RESULTS: In total, 55 engagement activities were held (24 meetings, 20 workshops 11 educational sessions), with n = 96 staff from multiple disciplines participating in the ePROs implementation through advisory meetings, process mapping, change management and staff education. Decisions were made regarding eligible patient cohorts to include, the process for onboarding patients onto the ePRO system, and follow-up and referral pathways. Rationales for decisions included alignment with existing workflows, utilizing available staff, minimizing staff and patient burden and maximizing patient engagement. CONCLUSION: Existing resources, staff input and technical and logistical reasons often guided the ICP decisions, highlighting the need for in-depth engagement across all stakeholders for optimal implementation of ePRO ICPs. The ePRO implementation required substantial dialogue and systematic resolution to reach agreement on the final processes. Adapting the local ICP through rigorous engagement facilitated the successful implementation of ePROs as business-as-usual at all three cancer centres. Involving all relevant stakeholders is critical to the successful adaptation of ICPs before their introduction into routine care.

Barriers and facilitators to the availability of efficacious self-directed digital health tools for adults living with cancer and their caregivers: A systematic literature review and author survey study.

OBJECTIVE: This study aimed to examine barriers and facilitators to the dissemination of efficacious self-directed digital health tools for adults affected by cancer, and quantify funding used to develop and evaluate these digital health tools. METHODS: We conducted: (1) a systematic literature review to identify efficacious self-directed digital health tools for adults affected by cancer, published between 2009 and 2019 and (2) an author survey to identify barriers and facilitators to dissemination of those tools, grant funding and the user centredness of their design (UCD) process. RESULTS: Of 1314 screened articles, 29 articles describing 26 tools met the inclusion criteria. From 26 surveys sent, 12 were completed, 6 of which described disseminated tools. Whilst researchers' motivation and infrastructure support facilitate tool dissemination, limited funds, lack of infrastructure and limited research timelines are the most common barriers. A median of AUD$250,000 was spent on tools not disseminated to end-users. CONCLUSION: Although incorporating UCD processes in the development of digital health tools is important, it is imperative to integrate implementation processes into the planning stages of tool development to ensure dissemination. PRACTICE IMPLICATIONS: Researchers, academic institutions, funding agencies and government and non-government organisations all have roles to play to support long-term implementation.

The male perspective: A mixed methods study of the impact, unmet needs and challenges of caring for women with breast cancer.

OBJECTIVES: As a formative investigation toward the development of a supportive care intervention for male caregivers, this study explored the emotional impact, unmet needs and challenges experienced by men when caring for a woman with breast cancer. DESIGN: A cross-sectional mixed methods study, with an online survey and interviews. SAMPLE: A total of 89 participants completed the survey, of whom 13 completed interviews. The majority (93%) of participants were husbands of care recipients; of the care recipients, 75% had early stage breast cancer and 45% were diagnosed over 5 years ago. METHOD: Participants completed questionnaires assessing their emotional wellbeing, unmet needs and biopsychosocial challenges, with a sub-sample participating in subsequent interviews to elaborate on survey responses. FINDINGS: Emotional difficulty was reported by <25% of the sample, and 83% reported experiencing at least one unmet need (M = 81.5, SD = 33.2). Of the 39 biopsychosocial challenges presented, 100%, 86% and 73% reported "ever experiencing," "currently experiencing," and "ever needing help," respectively. Interviewed participants echoed the most reported needs and challenges as changes to sex life, fear of recurrence and lack of practical information. CONCLUSIONS: Male cancer caregivers experience diverse challenges and require psychological support and practical information using both online and offline approaches to support their caregiving responsibilities. IMPLICATIONS FOR PSYCHOSOCIAL PROVIDERS: Healthcare professionals can support male caregivers by: being aware of their information and psycho-social needs; directing caregivers to online interventions for additional information; and facilitating the provision of online psycho-sexual and FCR support.

What Male Caregivers of Women With Breast Cancer Want in an Online Intervention: A Qualitative Study.

The diversity in cancer caregiver responsibilities often leaves caregivers feeling ill-prepared for their role. To inform the development of an online caregiver training intervention, we examined the views of men caring for a woman with breast cancer on intervention mode, timing, and content preferences. Thirteen men participated in a qualitative interview. The findings reveal that an online intervention should include educational content and psychological support, be interactive and personalized, and be available from the point of diagnosis. There is encouraging support for an online caregiver training intervention that covers numerous topics and is available for men to tailor how they use the content based on their individual needs.

Development and usability evaluation of an online self-management intervention for fear of cancer recurrence (iConquerFear).

OBJECTIVE: To develop and evaluate the usability of iConquerFear, an online self-management adaptation of an efficacious face-to-face therapist-delivered treatment for fear of cancer recurrence (FCR). METHODS: iConquerFear development was theory based and person based. Development was guided by Ritterband et al's behaviour change model for internet interventions. iConquerFear end users (cancer survivors) provided iterative feedback in accordance with Yardley et al's person-based approach to maximise engagement and usability. Online focus groups and cognitive interviews were conducted to evaluate the usability of iConquerFear. Discussions were recorded, transcribed verbatim, and thematically analysed. RESULTS: Five online FCR modules were developed. Twenty-three cancer survivors (47% of those eligible) participated; 11/23 (58%) were breast cancer survivors, and average age was 53 years (SD = 10.8). Thematic saturation was reached after six focus groups (n = 16) and seven individual think-aloud interviews. Thematic analysis produced five overarching themes: easy navigation essential; satisfaction and engagement with content; flexible access is key; normalising and empowering; and a useful first step. CONCLUSIONS: Online self-management interventions like iConquerFear have the potential to address the unmet supportive care needs reported by burgeoning numbers of cancer survivors. However, that potential may not be realised unless interventions are rigorously developed and user tested, as benefits are constrained by limited engagement. Themes from the usability testing of iConquerFear highlight the importance of developing flexible, tailored, interactive, and contextual online self-management interventions for people with cancer.

Safe Food Management and Smartphone Technology: Investigating the Impact of an App on Consumer Knowledge Retention.

OBJECTIVES: Diffusion of smartphones has normalised consumers' use of mobile applications (apps). But how do app designs and contexts of use interact with differential consumer attributes to impact on their effectiveness, usability and value over time? For consumer food safety, answering these questions is of importance as numerous food choices increase challenges in safe food management (SFM). This research reports on results of a randomised field experiment with Australian consumers using an SFM mobile app developed by the researchers. METHOD: The SFM app development employed insights from the Health Literacy Online Heuristics framework and the experiment involved evaluation of information and/or knowledge acquisition from the app versus from a paper-based version. The experiment spanned four weeks and involved eight participants (experimental group n=4; control group n=4). RESULTS: The results highlight differentials in cognitive burden between paper and the app; beneficial affordances from the app for refreshing consumer knowledge; and longer knowledge retention on safe food management from app use over-time. DISCUSSION: We identified two key impacts of the app on consumer knowledge acquisition and knowledge retention. First, the SFM app takes longer to achieve knowledge acquisition but results in longer knowledge retention than the control. Second, the SFM app induces some level of cognitive load in adoption however; the affordance of its reuse for quick but infrequent revisitations facilitates knowledge retention. Although the study is limited by the small sample size, it however highlights the need for a large scale and purely quantitative investigation that are generalisable to the Australian population. CONCLUSION: It is anticipated that the insights gained from this study can be used to develop nationwide interventions for addressing consumer SFM knowledge gaps in the home; thus, moving a step closer towards addressing SFM behaviours of Australian consumers.
