Introduction The unproven stem cell intervention (SCI) industry markets stem cell products to patients navigating chronic and serious conditions who seek alternative options when conventional treatments no longer offer relief or improvement. This market is often characterized by providers using deceptive advertising to misinform potential consumers to seek stem cells that have not been shown to be safe and/or effective through clinical studies. Objective This study examines how patients describe interpersonal and institutional trust in relation to their interest in and decisions about unproven SCIs among two distinct and divergent chronic disease patient groups: patients with little or no interest in unproven SCIs (low seekers) and those with high interest or have undertaken an unproven SCI (high seekers). Methods A semi-structured interview guide was developed deductively and modified inductively based on the Unified Theory of Health Behavior. Qualitative interviews among 36 patients and carers were conduct and transcripts were analyzed using constant comparison based on the principles of grounded theory. Results Trust varies across social contexts as low seekers expressed strong reservations about the commercialization elements of the SCI industry placing greater confidence in conventional medicine. In contrast, high seekers questioned the advice of conventional providers and motives of medical regulators. Across both, personal relationships were commonly described as influential in how participants evaluated unproven SCIs. Conclusion These findings suggest that communication efforts in clinical settings should account for the relational and emotional dimensions of trust. Interventions aimed at countering misleading information and promoting informed choices should engage trusted messengers and address the broader social and psychological contexts in which patients may seek unproven SCIs.

A Prospective Video-Reflexive Ethnographic Study of Direct Patient-Pathologist Interactions With Heart and Lung Allograft Recipients
Context.— A clinic was created for patients to review their explanted organs with a pathologist. Objective.— To prospectively investigate the benefits of this type of clinic as perceived by both transplant patients and their pathologists. Design.— In this prospective study, patients participated in a videotaped viewing of heart and/or lung explants by the patient and their guest(s) and pathologist (December 2017–August 2022). Patients received a 3D-printed replica of their explant. After viewing the explanted organ, patients and their guests participated in an interview to assess their experiences. Video-reflexive ethnography was used by pathologists for data collection and practice improvement. Results.— Of 143 patients who viewed their explanted organ, 21 patients consented to having the organ-viewing session taped and to participate in a postviewing interview. The study group was comprised of 12 men; the median age was 57.5 years (range, 29–67 years). Five pathologists took part in reflexive sessions. The clinics were viewed positively by patients, providing an opportunity to better understand their disease. Pathologists had a similarly positive experience and gained important insights to patient journeys. Proposals for improvement were brought forward from both patients and pathologists. Conclusions.— Video-reflexive ethnography provided the opportunity for patients and pathologists to reflect on patient-pathology clinic appointments. This work serves as a template to build out pathology-based clinics.
Toward Patient-Centered AI Fact Labels: Leveraging Extrinsic Trust Cues
Proceedings of the 2025 ACM Designing Interactive Systems Conference | July 4, 2025 | Volume: No volume available | Issue: No issue available | Pages: 676-690
Background: Cervical cancer screening with a self-collected vaginal specimen for human papillomavirus (HPV) testing was approved by the U.S. Food and Drug Administration in May 2024, offering a potential solution to declining screening rates. Objective: We aimed to assess acceptability of clinic-based vaginal specimen self-collection for HPV testing and to evaluate associations between participants’ sociodemographics and their likelihood of choosing self-collection for future screening and the overall acceptability of using the Evalyn® brush device. We also evaluated associations between specific acceptability constructs and reported likelihood to use the device in the future and overall acceptability. Methods: Following self-collection of a vaginal specimen, participants completed an electronic survey that measured constructs from the Theoretical Framework of Acceptability. Associations were assessed using logistic regressions. The study was conducted at a colposcopy clinic in the Gynecology department of a midwestern academic medical center in the United States from November 2022 through July 2023. Results: Participants ( n = 81) reported high likelihood (98% likely or very likely) of choosing in-home self-collection for future screening and unanimity on overall acceptability (100% acceptable or completely acceptable) of using the device. More affirmative responses to measures on instruction understandability, ease of device use, understanding the device is used for cervical cancer screening, and perceiving self-collection improves screening rates were associated with a higher likelihood to choose self-collection for future screenings and overall acceptability of the device (all p values <0.05). Conclusion: Vaginal specimen self-collection for HPV testing was well-received in the studied population, with high acceptability and likelihood of uptake. Implementation efforts should provide user-friendly instructions and emphasize the benefits of self-collection for cervical cancer screening, particularly among people less likely to engage with clinician-collected speculum-based screening.
Attitudes and Experiential Factors Associated with Completion of mt-sDNA Test Kit for Colorectal Cancer Screening
Colorectal cancer (CRC) is the third leading cause of cancer-related deaths in the United States. Despite the availability of multiple screening options, CRC screening is underutilized. We conducted a survey of patients (n = 2973) who were prescribed the multi-target stool DNA (mt-sDNA) screening test (commercialized as Cologuard ® and manufactured by Exact Sciences Corporation) to understand attitudes and experiences that influence test completion and likelihood of future test completion. Using exploratory factor analyses, we developed three scales: Perceived Effectiveness, Perceived Ease of Use, and Perceived Comfort.
Patient-provider communication factors associated with mt-sDNA screening for colorectal cancer.
e22514 Background: Several colorectal cancer (CRC) screening tests, shown to reduce CRC incidence and mortality, are recommended for average-risk adults aged 45-75 years. CRC screening is underutilized in the US with access to facility-based options, such as colonoscopy, representing a barrier to screening. Stool-based tests are guideline-endorsed and offer patients a convenient and more accessible CRC screening option that can be completed at home. Provider recommendation is consistently identified as the primary factor driving patient adherence. Understanding how aspects of patient-provider communication influence CRC screening can inform interventions to improve adherence. We developed a survey, informed by behavioral theory, to identify communication factors associated with completion of mt-sDNA screening. Methods: Adults aged 45-75 years, with a US postal address, who received a valid order for mt-sDNA and whose kit was shipped between 5/21-9/21 were eligible for sampling. The survey was administered by RTI International between 3/22-6/22. Participants could complete electronic or paper surveys. We fit a multivariable logistic regression to identify patient-provider communication factors associated with mt-sDNA test completion. Results: 2,973 respondents completed the survey (response rate = 21.7%). The majority (77.3%) completed the mt-sDNA test and said they would be ‘very likely’ (76.8%) to complete Cologuard in the future. The proportion of respondents who had conversations with their healthcare provider about Cologuard, and the specific content of those conversations, was significantly different between completers and non-completers and between respondents who said they were ‘very likely’ to complete Cologuard in the future compared to respondents who were not. Results from a binary logistic regression suggested that discussions with a healthcare provider related to step-by-step instructions for completing Cologuard (OR = 1.62) and needing to have a colonoscopy follow-up (OR = 1.93), as well as feeling included ‘a great deal’ in the decision-process with respondents’ healthcare provider (compared to ‘somewhat’ or ‘not at all’) increase the odds of kit completion. Additionally, healthcare provider discussions relating to test cost (OR = 1.47) and performance (OR = 1.72), as well as feeling included ‘a great deal’ in the decision-process was positively associated with respondents indicating they were ‘very likely’ to use Cologuard in the future. Provider discussions about the cost of a follow-up colonoscopy was negatively associated with a ‘very likely’ future user (OR = 0.52). Conclusions: Healthcare providers play a key role in patient adherence to CRC screening and must be appropriately prepared and resourced to educate and to engage patients in shared decision-making about CRC screening.
Abstract 770: Provider communication contributes to colorectal cancer screening intention through improving screening outcome expectancies and perceived behavioral control
Abstract Background: Multiple guideline-recommended colorectal cancer (CRC) screening options have been shown to reduce CRC incidence and mortality among average-risk patients. Yet, CRC screening continues to be underutilized in the US. Provider recommendation has consistently shown to improve screening completion. Our study aimed to delineate the pathways through which provider communication influences CRC screening completion. We tested how provider communication about the "Why” and “How” of mt-sDNA screening contributes to mt-sDNA screening intention through influencing patients’ screening outcome expectancies and perceived behavioral control. Methods: Data came from a behavioral theory-informed survey that we developed to identify psychosocial factors associated with mt-sDNA screening. The survey was administered between 3/22-6/22 by RTI International, with a sample of US adults ages 45-75 who received a valid order for mt-sDNA screening with a shipping date between 5/21-9/21. Participants completed an electronic or paper survey. We measured patients’ reports of providers’ “Why” communication with items on mt-sDNA screening performance, advantages/disadvantages, and cost. Providers’ “How” communication was measured with items on instructions and need for follow-up testing. We tested the proposed relationships using structural equation modeling and tested indirect effects using bootstrapping. Results: A total of 2973 participants completed the survey (response rate: 21.7%). “Why” communication was positively associated with perceived effectiveness of mt-sDNA screening (b = 0.349, p < .001) and negatively associated with CRC worry (b = -0.078, p = .002). “How” communication was positively associated with perceived ease of use (b = 0.392, p < .001) and perceived comfort of mt-sDNA screening (b = 0.138, p < .001). Perceived effectiveness and perceived ease of use were positively associated with intention to complete mt-sDNA screening (b = 0.404, p < .001; b = 0.339, p < .001). “Why” communication contributed to screening intention through influencing perceived effectiveness (b-indirect effect = 0.141, 95% CI: 0.115, 0.177). “How” communication contributed to screening intention through influencing perceived ease of use (b-indirect effect = 0.133, 95% CI: 0.104, 0.172). Conclusions: Improving patients’ beliefs about the effectiveness and ease of use of screening may be one pathway through which provider communication contributes to CRC screening completion. Efforts are needed to develop and implement provider-patient communication strategies and toolkits that are efficacious at fostering patient understanding of the rationale for CRC screening and the effectiveness of available screening options as well as addressing barriers and enhancing patients’ self-efficacy in completing their preferred screening option.

A Community Paramedic Clinic at a Day Center for Adults Experiencing Homelessness
61 Background: Although several guideline-recommended colorectal cancer (CRC) screening modalities have been shown to reduce CRC incidence and mortality, adherence remains below U.S. public health goals. Patient navigation services have been shown to improve CRC screening completion. Patient navigation services, including outbound phone, text, and e-mail reminders, and inbound phone support (>200 languages) are included with all mt-sDNA test (Cologuard) orders. A website and financial assistance (upon request and qualification) are also available for patients. We developed a survey, informed by behavioral theory, to identify psychosocial and communication factors associated with completion of mt-sDNA screening including questions to evaluate awareness and use of navigation services. Methods: Adults aged 45-75 years, with a US postal address, who received a valid order for mt-sDNA screening between 5/21-9/21 were eligible for sampling. RTI administered the survey between 3/22-6/22. Participants had the option to complete electronic- or paper-based surveys. We conducted crosstabulation with Chi Square to assess whether awareness and use of navigation services was significantly associated with (a) test completion within 6 months of the order date and (b) likelihood of future mt-sDNA use. Results: 2,973 participants completed the survey (RR= 21.7%; 65.15% by web and 34.85% by paper). Responders and non-responders did not differ significantly by age or sex. For each navigation service, awareness was significantly higher among those who completed the mt-sDNA test compared to those did not. Across all services, awareness was significantly higher among respondents reporting they were ‘very likely’ to complete mt-sDNA if recommended by a healthcare provider in the future than all other responses combined. A significantly higher proportion of completers (vs. non-completers) reported receiving the email reminder, using the Cologuard website, and using the English language inbound phone support. A significantly higher proportion of those “very likely” to complete mt-sDNA screening in the future reported receiving the email reminder, using the Cologuard website, and using the English language inbound phone support. Conclusions: Awareness and use of patient navigation services was associated with higher completion of the mt-sDNA test and with greater likelihood of future mt-sDNA test use. Patient navigation services comprised of evidence-based strategies, such as reminders, support patient adherence to CRC screening.
