Objectives This study aimed to describe how health researchers identify and counteract fraudulent responses when recruiting participants online. Design Scoping review. Eligibility criteria Peer-reviewed studies published in English; studies that report on the online recruitment of participants for health research; and studies that specifically describe methodologies or strategies to detect and address fraudulent responses during the online recruitment of research participants. Sources of evidence Nine databases, including Medline, Informit, AMED, CINAHL, Embase, Cochrane CENTRAL, IEEE Xplore, Scopus and Web of Science, were searched from inception to April 2024. Charting methods Two authors independently screened and selected each study and performed data extraction, following the Joanna Briggs Institute’s methodological guidance for scoping reviews and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines. A predefined framework guided the evaluation of fraud identification and mitigation strategies within the studies included. This framework, adapted from a participatory mapping study that identified indicators of fraudulent survey responses, allowed for systematic assessment and comparison of the effectiveness of various antifraud strategies across studies. Results 23 studies were included. 18 studies (78%) reported encountering fraudulent responses. Among the studies reviewed, the proportion of participants excluded for fraudulent or suspicious responses ranged from as low as 3% to as high as 94%. Survey completion time was used in six studies (26%) to identify fraud, with completion times under 5 min flagged as suspicious. 12 studies (52%) focused on non-confirming responses, identifying implausible text patterns through specific questions, consistency checks and open-ended questions. Four studies examined temporal events, such as unusual survey completion times. Seven studies (30%) reported on geographical incongruity, using IP address verification and location screening. Incentives were reported in 17 studies (73%), with higher incentives often increasing fraudulent responses. Mitigation strategies included using in-built survey features like Completely Automated Public Turing test to tell Computers and Humans Apart (34%), manual verification (21%) and video checks (8%). Most studies recommended multiple detection methods to maintain data integrity. Conclusion There is insufficient evaluation of strategies to mitigate fraud in online health research, which hinders the ability to offer evidence-based guidance to researchers on their effectiveness. Researchers should employ a combination of strategies to counteract fraudulent responses when recruiting online to optimise data integrity.

Existing reviews have identified factors influencing Clinical Decision Support (CDS) adoption by clinicians in practice but overlook the dynamic and evolving nature of technology and users’ needs over time. This review aimed to identify factors that influence early, mid-term, and sustained acceptance and use of CDS in hospital settings. Five databases were searched from 2007 to January 2024 and 67 papers were included. Factors were extracted and synthesised according to the time that data were collected following CDS implementation. Factors relating to the CDS intervention (e.g. utility) and inner setting (e.g. fit with workflows) were reported across all time periods. Perceived outcomes were more often identified in the first year of use, and individual factors after the first 6 months of use. Strategies to work around CDS limitations were reported 5 years after implementation. Our review provides guidance for developing, implementing, and supporting ongoing use of CDS systems.

PURPOSE: Patients with cancer commonly report distress and fear of cancer recurrence (FCR) impacting quality of life and clinical outcomes. This study aims to test the association between emotional well-being and clinical characteristics of survivors with localized renal cell carcinoma (RCC). MATERIALS AND METHODS: Survivors with localized RCC were invited to participate in this study through social media by the Kidney Cancer Research Alliance. Participants self-reported clinical characteristics, distress (Distress Thermometer), and FCR (Fear of Cancer Recurrence-7). Ordinal regression was used to test the association between emotional well-being and patient characteristics. RESULTS: A total of 412 survivors were included in this analysis. Participants were mostly female (79.4%) and well educated (58.3%), with a median age of 54 years (range, 30-80 years) and median time since diagnosis of 17.5 months. More than one half were diagnosed with stage I disease (56.1%). Most patients (62.3%) had a clear understanding of their diagnosis. A high prevalence of moderate to severe distress (67.0%) and FCR (54.9%) was reported across all survivors of RCC. Higher FCR was associated with female gender, younger age, and lack of understanding of their diagnosis ( P = .001), whereas more recent diagnosis was associated with higher distress levels ( P = .01). CONCLUSION: Our findings suggest that FCR is a common problem that is persistent after therapy and that certain individuals, including female and younger patients, may be at particular risk of experiencing clinically relevant FCR.
