Why ethnic minority groups are under-represented in clinical trials: a review of the literature

Ethnoracial Representation in United States Clinical Trials for Retinal Vein Occlusion

PURPOSE

Retinal vein occlusion (RVO) is the second most common cause of vision loss from retinal vascular disease. Clinical trials often lack adequate representation of minority groups, limiting the external validity and equity of trial results. We aimed to characterize the evolution of ethnoracial demographic reporting, changes in the racial and ethnic composition of RVO trial participants, and correlations with trial sponsor and collaborator types.

DESIGN

Retrospective trend study.

SUBJECTS

Participants, sponsors, and collaborators in RVO clinical trials based in the United States (U.S.).

METHODS

We assessed the ethnoracial distribution of patients and sponsors and collaborators in RVO clinical trials. Trial data was sourced from ClinicalTrials.gov and compared with 2022 U.S. Census Bureau data.

MAIN OUTCOME MEASURES

Change in ethnoracial reporting and representation, and comparison of representation within RVO clinical trials with 2022 U.S. Census demographics.

RESULTS

Racial data was not documented for all 6 (12.2%) trials completed between 2008 and 2011. There was increased ethnoracial reporting between January 2012 and June 2017 (n = 6/29, 20.7%) vs July 2017 to December 2022 (n = 13/14, 92.9%) (OR 49.8; 95% CI: 5.39-460.47; P < .0001). The proportion of Asian participants increased from 4.2% to 15.9% (OR 4.37; 95% CI 2.49-8.37; P < .0001), and Black participants rose from 6.1% to 20.7% (OR 4.03; 95% CI 2.51-6.85; P < .0001). Conversely, White participants decreased from 73.8% to 56.0% (OR 0.45, 95% CI 0.34-0.59; P < .0001), and Hispanic/Latino participants decreased from 13.1% to 5.4% (OR 0.38; 95% CI 0.26-0.56; P < .0001). Compared to the 2022 U.S. Census data, the ethnoracial distribution of the total U.S. population is significantly different than the total enrollment in RVO clinical trials (P < .0001). Government and academic involvement were correlated with less White and more Black representation respectively (P ≤ .01).

CONCLUSIONS

From 2008 to 2022, there has been a notable increase in the documentation of racial and ethnic demographics in RVO clinical trials. Although the recruitment of Asian and Black patients has increased, the Hispanic population remains significantly underrepresented among RVO trial participants, highlighting the need for greater inclusivity in enrollment.

Understanding Barriers and Facilitators for Ethnic Minority Groups to Audio Recording Recruitment Discussions in Clinical Trials: A Participatory Approach to Improving Informed Consent and Participation

INTRODUCTION

Fully informed consent is essential for ethical trial conduct, yet gaps in participant comprehension and recall can occur, particularly among underserved groups, for example, ethnic minorities. This Patient and Public Involvement and Engagement (PPIE) project explored the engagement of ethnic minority communities in trial recruitment discussions, particularly their views about audio recording discussions with healthcare professionals.

METHODS

This PPIE project engaged ethnic minority communities in Bristol, collaborating with community partners to facilitate access to then foster dialogue among Somali, South Asian and Chinese groups. Separate workshops for men and women from these ethnic groups were held to introduce community members to clinical trial processes. Discussions, both audio recorded and not, simulated real recruitment scenarios. To ensure cultural relevance and accessibility, discussions were partly facilitated by our PPIE community partners in native languages.

RESULTS

The insights gained during workshops were organised into key themes. Gaps in understanding regarding clinical trial participation were highlighted. A key finding was that trust played an important role and was facilitated by engaging community leaders and ensuring cultural and linguistic sensitivity during discussions. To address gaps in knowledge about trials and streamline the educational process, we developed storyboards and multilingual video resources. These explained the importance of clinical trials generally and the importance of recruiting diverse patient populations in particular. The materials were co-created with community partners and refined through iterative feedback to ensure accuracy and cultural appropriateness. The challenge of language barriers necessitated skilled interpreters, especially when discussions were audio recorded, to optimise understanding among people from diverse ethnic backgrounds. The video, available in English, Urdu, Mandarin, Cantonese and Bangla, facilitates understanding of trial purposes and processes, with the aim of widening trial participation in these groups.

CONCLUSION

Our PPIE activities highlighted gaps in understanding, the critical role of trust and the challenge of language barriers. The co-created resources have been made available for those wanting to address and overcome some of these issues. The initial feedback from the clinical trials community on the video resources has been promising, underscoring their potential to impact future recruitment efforts and PPIE activities.

PATIENT OR PUBLIC CONTRIBUTION

To foster a co-creation process, this project included the active involvement of our PPIE collaborators and co-applicants 'Khaas' for funding. They also helped us reach contributors from the South Asian community (mainly of Pakistani and Bangladeshi origin) and arrange workshops. Our two PPIE contributors from Somali Resource Centre and Barton Hill Activity Club helped us reach the Somali community at the Wellspring Settlement. Similarly, the Chinese Community Wellbeing Society helped us reach people from the Chinese community. These PPIE partners also helped us run the workshop by providing live translation of discussion. They also helped translate video scripts and do voiceovers in videos. Also, PPIE contributors Tom Yardley and Amanda Roberts helped with the script development.

Clinical factors predicting the rate of cognitive decline in a US memory clinic: An electronic health record study

INTRODUCTION

Dementia progression is heterogeneous and predicting who will decline quickly remains an open problem. Most work in this area has focused on volunteer-based cohorts, which are subject to recruitment biases. Instead, we examine predictors of rate of cognitive decline in cognitive assessment scores using electronic health record (EHR) data from a US memory clinic.

METHODS

Data include patients with their first memory clinic visit (baseline) between January 1, 2014 and May 31, 2024. We used a discrete-time model to identify significant predictors of baseline and 6 month change in Mini-Mental State Examination (MMSE) scores (Montreal Cognitive Assessment scores were converted to MMSE equivalents for analysis). Inverse probability weighting was used to account for selection and censoring biases and p values were adjusted for multiple comparisons.

RESULTS

The cohort included 9583 patients, of which 7113 had a baseline cognitive assessment. Average MMSE at baseline was 23.2. Variables associated with lower baseline MMSE included female sex, non-White race, Medicaid enrollment, baseline dementia diagnosis, and cholinesterase inhibitor prescription, while higher scores were associated with prior diagnoses of chronic pain or fatigue. Quicker post-baseline decline was associated with older age, dementia diagnoses, and cholinesterase inhibitor prescription, while slower decline was associated with a higher number of total prescriptions, distance from home to clinic, and Social Deprivation Index. Notably, rate of decline was not associated with mild cognitive impairment, other non-dementia cognitive impairment, or any of the comorbidities considered.

DISCUSSION

While several significant predictors were identified, the lack of associations with broad categories of comorbidities and social determinants of health suggest that finer grained predictors may be needed. Additionally, the finding that cholinesterase inhibitor prescriptions predicted quicker decline merits additional investigation in real-world samples. The model developed in this work may serve as a first step toward an EHR-based progression risk tool.

Highlights

In a memory clinic setting, faster decline in Mini-Mental State Examination scores was associated with age, dementia diagnosis, and cholinesterase inhibitor or memantine prescription.Slower decline was associated with the patient's total number of prescriptions.Neither race nor ethnicity were associated with rate of decline, nor were baseline mild cognitive impairment, other non-dementia cognitive impairment, diabetes, hypertension, obesity, depression, anxiety, chronic pain/fatigue, or hearing loss.

The feasibility of culturally adapted computerised cognitive remediation for first-episode psychosis

BACKGROUND

British South Asians have a greater incidence of psychotic illness, which is associated with cognitive deficits. Computerised cognitive remediation aims to improve cognition.

AIMS

We aimed to culturally adapt computerised cognitive remediation for British South Asians with first-episode psychosis, and assess its feasibility.

METHOD

Qualitative interviews were analysed using thematic analysis to guide cultural adaptation of cognitive remediation, followed by a case series to determine feasibility. Our sample comprised 20 participants: ten in the qualitative interviews and ten in the feasibility evaluation. The sample was generated via purposive sampling from early intervention services in England, and was an entirely Muslim cohort, who were mainly Pakistani and born in the UK. Our intervention was computerised interactive remediation of cognition training for schizophrenia (CIRCuiTS), which was culturally adapted based on formative qualitative interviews and using an established framework. Participants engaged with 40 h of tasks over 12 weeks, with the aim of improving attention, memory and executive functioning. Feasibility was explored by assessing acceptability, engagement and retention in the study, and a range of measures were used to assess impact on cognition and mental state.

RESULTS

The cultural adaptation of CIRCuiTS was found to be acceptable, with high levels of engagement and satisfaction. Despite the small sample, the intervention led to improved cognition and mental state.

CONCLUSIONS

This is the first study to culturally adapt computerised cognitive remediation for British South Asians who are Muslim, and it had high acceptability with good retention, engagement and satisfaction. Future effectiveness testing is recommended.

Barriers and facilitators for engaging underrepresented ethnic minority populations in healthcare research: an umbrella review

BACKGROUND

Research highlights that participation of ethnic minority individuals in research is low when compared to white counterparts. This poses challenges for healthcare planning and delivery, as lack of representativeness in research means that findings are generalised across all ethnic groups, and do not provide stakeholders with a full picture of how minority populations are affected. This contributes to health inequalities as these populations may then be underserved and not get the best possible management if differences due to ethnicity were to exist. This study synthesises the barriers to engaging minority individuals in research to understand, and enablers to better engagement of different minority communities in healthcare research.

METHODS

Five databases were searched (MEDLINE, CINAHL, PsycINFO and Web of Science and EMBASE) up to 29th April 2024, resulting in 897 articles, of which 11 met the inclusion criteria. Data were extracted from reviews and synthesised using qualitative meta-aggregation techniques. The socio-ecological framework was applied to synthesise the main outcomes. A protocol for this review was registered on PROSPERO (CRD42024532686).

RESULTS

The main barriers for research participation included: mistrust of healthcare professionals, research and researchers; socioeconomic and logistical challenges; language and cultural barriers; lack of awareness; external influences and perceived bias. Facilitators to support better research participation included: Community engagement and personalised approaches; culturally sensitive research strategies; linguistically appropriate study materials and study advertising; education workshops.

CONCLUSIONS

To enable wider participation, it is important to understand not only the barriers but also to employ culturally appropriate facilitators, engaging with patient and public involvement (PPI) groups that communities trust, offer cultural training for researchers, and adopt a more collaborative and transparent way of working. This overview highlights the work that needs to be done on an intrapersonal, interpersonal, community and policy level to make research accessible and inclusive for ethnic minority groups.

Augmenting Insufficiently Accruing Oncology Clinical Trials Using Generative Models: Validation Study

BACKGROUND

Insufficient patient accrual is a major challenge in clinical trials and can result in underpowered studies, as well as exposing study participants to toxicity and additional costs, with limited scientific benefit. Real-world data can provide external controls, but insufficient accrual affects all arms of a study, not just controls. Studies that used generative models to simulate more patients were limited in the accrual scenarios considered, replicability criteria, number of generative models, and number of clinical trials evaluated.

OBJECTIVE

This study aimed to perform a comprehensive evaluation on the extent generative models can be used to simulate additional patients to compensate for insufficient accrual in clinical trials.

METHODS

We performed a retrospective analysis using 10 datasets from 9 fully accrued, completed, and published cancer trials. For each trial, we removed the latest recruited patients (from 10% to 50%), trained a generative model on the remaining patients, and simulated additional patients to replace the removed ones using the generative model to augment the available data. We then replicated the published analysis on this augmented dataset to determine if the findings remained the same. Four different generative models were evaluated: sequential synthesis with decision trees, Bayesian network, generative adversarial network, and a variational autoencoder. These generative models were compared to sampling with replacement (ie, bootstrap) as a simple alternative. Replication of the published analyses used 4 metrics: decision agreement, estimate agreement, standardized difference, and CI overlap.

RESULTS

Sequential synthesis performed well on the 4 replication metrics for the removal of up to 40% of the last recruited patients (decision agreement: 88% to 100% across datasets, estimate agreement: 100%, cannot reject standardized difference null hypothesis: 100%, and CI overlap: 0.8-0.92). Sampling with replacement was the next most effective approach, with decision agreement varying from 78% to 89% across all datasets. There was no evidence of a monotonic relationship in the estimated effect size with recruitment order across these studies. This suggests that patients recruited earlier in a trial were not systematically different than those recruited later, at least partially explaining why generative models trained on early data can effectively simulate patients recruited later in a trial. The fidelity of the generated data relative to the training data on the Hellinger distance was high in all cases.

CONCLUSIONS

For an oncology study with insufficient accrual with as few as 60% of target recruitment, sequential synthesis can enable the simulation of the full dataset had the study continued accruing patients and can be an alternative to drawing conclusions from an underpowered study. These results provide evidence demonstrating the potential for generative models to rescue poorly accruing clinical trials, but additional studies are needed to confirm these findings and to generalize them for other diseases.

Sangre Por Salud (SPS) Biobank: cohort profile

PURPOSE

The Sangre Por Salud (SPS) Biobank was established to facilitate biomedical research opportunities for the Latino community by creating an easily accessible prospective cohort for scientists interested in studying health conditions and health disparities in this population.

PARTICIPANTS

Individuals self-identifying as Latino, aged 18-85 years, were prospectively recruited from the primary care Internal Medicine clinic at Mountain Park Health Center in Phoenix, Arizona. After obtaining informed consent, detailed medical history questionnaires were captured, and blood samples were obtained for common laboratory tests. Participants authorised the research team to access their electronic health records for research purposes. In addition, participants had serum, plasma and DNA samples isolated and stored at the Mayo Clinic Arizona Biorepository Laboratory for long-term storage and future access. As part of the study, participants consented and agreed to be contacted for potential participation in future research studies.

FINDINGS TO DATE

3756 participants provided informed consent, of whom 3733 completed all study questionnaires, an oral glucose tolerance test and had blood collected and stored. The SPS cohort is predominantly composed of females (72%), with a median age at time of consent of 42 years. All participants self-identified as Hispanic/Latino, 45% were married, 53% were employed for wages and 60% had less than a high school degree. Around 25% of participants met diagnostic criteria for overweight (BMI 25-29 kg/m2), and 49% met for obesity (BMI≥30 kg/m2). At time of recruitment, hypertension, hyperlipidaemia and depression affected 22%, 20% and 13% of the cohort, respectively.

FUTURE PLANS

We plan to regularly update the participants' electronic health records and self-reported health data to longitudinal research. Additionally, we plan to obtain a more comprehensive genomic analysis on the entire cohort, ensuring greater research interest and investigation into the underlying genetic factors that contribute to disease susceptibility in this cohort.

Algorithmic emergence? Epistemic in/justice in AI-directed transformations of healthcare

Moves toward integration of Artificial Intelligence (AI), particularly deep learning and generative AI-based technologies, into the domains of healthcare and public health have recently intensified, with a growing body of literature tackling the ethico-political implications of this. This paper considers the interwoven epistemic, sociopolitical and technical ramifications of healthcare-AI entanglements, examining how AI materialities shape emergence of particular modes of healthcare organization, governance and roles, and reflecting on how to embed participatory engagement within these entanglements. We discuss the implications of socio-technical entanglements between AI and Evidence-Based Medicine (EBM) for equitable development and governance of health AI. AI applications invariably center on the domains of medical knowledge and practice that are amenable to computational workings. This, in turn, intensifies the prioritization of these medical domains and furthers the assumptions which support the development of AI, a move which decontextualizes the qualitative nuances and complexities of healthcare while simultaneously advancing infrastructure to support these medical domains. We sketch the material and ideological reconfiguration of healthcare which is being shaped by the move toward embedding health AI assemblages in real-world contexts. We then consider the implications of this, how AI might be best employed in healthcare, and how to tackle the algorithmic injustices which become reproduced within health AI assemblages.

Towards equitable reporting of Indigenous status, ethnicity, language and country of birth in Australian paediatric clinical studies: A scoping review

AIM

This scoping review aims to expansively review the reporting of Indigenous status, ethnicity, culture, language and country of birth in Australian paediatric clinical studies.

METHODS

Scoping review of Australian clinical studies, including randomised controlled trials, non-randomised controlled trials, cluster randomised controlled trials and quasi-experimental studies, with paediatric participants (<18 years) or mixed adult and paediatric participants. PubMed, Cumulated Index to Nursing and Allied Health Literature and Embase databases were searched for clinical studies published 1 January 2018 to 28 November 2022.

RESULTS

Of the 2717 studies identified in the search, 209 clinical studies were included. Overall, 131 (62.7%) clinical studies captured in this review did not report any of the variables of interest. When reported, terms used by study authors varied extensively and subsequently five study-defined categories emerged 'Indigenous status', 'race', 'race and ethnicity', 'ethnicity', or 'natural skin colour'. 'Indigenous status' was most reported (n = 37, 17.7%), followed by 'ethnicity and/or cultural background' (n = 15, 7.2%), 'race and ethnicity' (n = 4, 1.9%), race (n = 1, 0.5%) and 'natural skin colour' (n = 1, 0.5%). Furthermore, language used at home was reported in 27 studies (12.9%) and country of birth in 23 studies (11.0%).

CONCLUSIONS

This review demonstrated very low reporting of Indigenous status, ethnicity, culture, language and country of birth in Australian paediatric clinical studies. Poor reporting has raised concerns surrounding generalisability of findings from these trials in addition to equity. The recent international shift encompassing improved clinical trial reporting requirements, for ethnicity and race, require prompt establishment in the Australian clinical trial domain.

Experiences of south Asian key workers in COVID-19 lockdowns in the United Kingdom

Background

This study aims to explore the experiences, challenges, and support given to South Asian Key Workers (food and necessary goods, Transport (delivery and taxi drivers,) working in the United Kingdom in times of the COVID-19 lockdowns between March 2020 to March 2021. The qualitative study aims to explore the experiences, challenges, and financial support given to South Asian Key Workers working in the United Kingdom in times of the COVID-19 lockdowns.

Methods

A phenomenological approach was used to explore the experiences of key workers during the COVID-19 lockdowns in the UK. Snowball sampling was used to contact participants, who were South Asian key workers working in food, necessary goods and transport during COVID-19 lockdown in United Kingdom. Semi-structured, in-depth face to face and telephonic interviews were conducted with study participants in February and March 2021. Inductive qualitative approach was used for data analysis, and data analysis was done parallel with data collection.

Results

Researcher interviewed 17 key workers. During the data analysis four theme categories emerged: 1) Precarious working conditions, 2) Coping with stress and fear, 3) Sustainability pressures, and 4) Insufficient support. Overall, the results show that the many participants had been working in close interaction with co-workers, customers and clients, poor protective measures to prevent catching infection, excessive workload, received limited support from employer, no access to furlough pay, restriction based on immigration status and limited economic support. Instead, they had to use self-devised strategies to cope with the increased workload, economic burdens and protection from infection.

Conclusion

The precarious working conditions exhausted participants physically and economically. They were holding a lot of grievances and hurt inside due to long existing inequalities in the society, where many highly educated and skilled individuals were unable to get stable and secure employments, despite the health vulnerabilities, South Asian key workers worked through the Covid-19 lockdowns to overcome difficulties stem from precarious work. Although currently coping with increased debts, economic burdens and long COVID symptoms, comprehensive job security and entitlement to secure contracts with provisions to sick leaves and pays should be made available to address economic vulnerabilities of south Asian key workers.

Access to Chronic Pain Services for Adults from Minority Ethnic Groups in the United Kingdom (UK): a Scoping Review

BACKGROUND

Chronic pain services in the UK are required to provide services which meet the diverse needs of patients, but little is known about the access and use of these services by minority ethnic groups.

OBJECTIVE

To assess the available evidence regarding the ethnic profile of adults who access secondary and tertiary chronic pain services in the UK.

METHODS

A scoping review was conducted (August 2021-October 2021), comprising comprehensive literature searches using Embase, Medline and CINAHL databases and the grey literature. Studies were included if they reported on (i) access to chronic pain services in secondary and/or tertiary care in the UK, (ii) adults and (iii) stated the ethnicity of the involved participants. Studies were included if published between 2004 and 2021, as demographic data during this period would be broadly representative of the UK population, as per the 2021 UK census. A descriptive synthesis of the extracted data was performed.

RESULTS

The search yielded 124 records after duplicates were removed. Following title and abstract screening, 44 full texts were screened, ten of which were included in the review.

CONCLUSIONS

This is the first review to explore access to chronic pain services for adults from minority ethnic groups in the UK. Given the limited number of studies that met the inclusion criteria, the review highlights the need for routine collection of ethnicity data using consistent ethnic categories within UK chronic pain services and increased involvement of minority ethnic groups within chronic pain research. Findings should inform future research that aims to improve access to UK chronic pain services for adults from minority ethnic groups.

Reporting Indigenous status, ethnicity, language and country of birth to build equity in international paediatric clinical trials with Australian sites: a scoping review

Objective Ensuring equitable access to clinical trials for children from Indigenous and ethnically and linguistically diverse backgrounds should be central to clinical trial design. This review aims to expansively review the reporting of Indigenous status (Aboriginal and/or Torres Strait Islander origin), ethnicity, culture, location, language and country of birth in paediatric clinical trials with Australian sites. Methods This scoping review systematically searched PubMed, CINAHL and Embase for international clinical trials with Australian sites conducted between 2018 and 2022 involving children (aged <18years) to determine the reporting of Indigenous status, race, ethnicity, language and country of birth. Results Of the 262 studies included, 154 (58.8%) clinical trials did not report any of the variables of interest. When reported, terms used by authors were heterogeneous. 'Indigenous status' was most reported (n =40, 15.3%) and self-identification was the most common method to determine this (n =14, 35.9%). International clinical trials had higher rates of reporting for ethnicity, cultural background and race. Overall, more than 60 terms were used to categorise study participants in relation to 'Indigenous status', 'ethnicity and cultural background', 'race', 'race and ethnicity' or 'natural skin colour'. Conclusions This review demonstrated low rates of reporting of demographic variables in paediatric clinical trials. Clear reporting standards, partnering with consumers to co-design trials and self-identification during collection are required. Ensuring adequate access to clinical trials for Indigenous children and children from ethnically, linguistically and geographically diverse backgrounds is essential in building health equity and ensuring patient safety.

Understanding the barriers and enablers to participation in vaccine trials in a pregnant population from diverse ethnic background in an inner-city UK hospital

BACKGROUND

Vaccination during pregnancy is an important healthcare intervention for safeguarding the health of the mother and their infants. Ethnic disparities in recruitment to vaccine research studies during pregnancy potentially contribute to health inequalities. The aim of the current study was to explore the barriers and enablers influencing the willingness of pregnant women from ethnic minority backgrounds to participate in vaccine research studies.

METHODS AND FINDINGS

Semi-structured qualitative online interviews were conducted with 23 pregnant women from diverse ethnic backgrounds in the UK. Interviews were transcribed verbatim, and thematically analysed. Our findings suggest that participants perceived vaccines and vaccine research, in principle, to be beneficial to the individual and to society, and understood the value of vaccination in mitigating severity of disease and protecting the health of mothers and their infants. Apprehension over the safety of vaccination in pregnancy was common and reduced willingness to participate. For those that decided to participate in vaccine trials in pregnancy, this was seen as an act of solidarity, a way to contribute to a collective responsibility for the public health of the community. Personal and community connections and representation-seeing people from their own communities represented in in the recruitment process shapped decisions about vaccine trial participating. Trust and mistrust in health systems, shaped by past experiences of interacting with healthcare professionals were likely to inform whether they would consider participating. Practical considerations such as excessive time commitments related to study procedures, travel and organising childcare were barrier to participation. The level of invasiveness of trial procedures were also a concern, although increased monitoring during the trial was seen as a potential benefit, mitigating some safety concerns.

CONCLUSIONS

Our study reinforcing previously identified barriers to vaccine participation among pregnant women from diverse ethnic communities. This study underlines the need to develop tailored interventions that focus on fostering trust with the aid of community engagement to understand cultural contexts, establishing authentic representation, and address practical considerations, to contribute to enhancing vaccine trial participation in pregnancy in those from diverse ethnic communities.

Bridging the Gap: Culturally Responsive Strategies for NIH Trial Recruitment

OBJECTIVE

To enhance recruitment and participation rates of non-Hispanic Black (NHB) and Hispanic adult patients in a NIH-funded clinical trial studying an emerging health technology.

DATA SOURCES AND STUDY SETTING

This study includes primary data collected in Los Angeles, California from November 2020 through November 2023.

STUDY DESIGN

To improve the representation of NHB and Hispanic patients in a NIH-funded (NCT04409353) trial on virtual reality for chronic lower back pain (cLBP), we conducted a multi-phase study utilizing a mixed-method approach. First, we conducted focus groups with NHB and Hispanic cohorts aged 18 and older; based on the feedback, we culturally adapted recruitment materials and study correspondences concordantly. Additionally, a cohort builder was used to filter the electronic medical record to isolate non-Hispanic Black (NHB) and Hispanic patients with cLBP for micro-targeted recruitment. These changes were collectively integrated when the parent NIH study had recruited 222 of its 385 final samples (57.7%), creating a pre-post comparison timepoint (May 17, 2022). Quantitative analysis was performed to assess the efficacy of the modified recruitment strategies by comparing the number of recruited and randomized NHB and Hispanic patients pre- and post-intervention.

DATA COLLECTION/EXTRACTION METHODS

Semi-structured focus groups were conducted with NHB and Hispanic patients and community members (age 18 and older). The focus groups were conducted online and recorded with participant consent; transcripts of the recording underwent inductive thematic analysis. Emergent themes directed the modification of study materials, including revised language and imagery, targeted outreach, and incorporation of treating physicians, were implemented in the second half of the study. Quantitative analyses were conducted following parent study completion by comparing records added to the screening database following the implementation of new recruiting methods (5/17/2022) to those added before.

PRINCIPAL FINDINGS

Thematic analysis of focus groups identified four key themes: mistrust, lack of interest, culture, and communication. Modifications to recruitment methodology resulted in statistically significant increases in the pre- to post-randomization success rate for the overall study population (p < 0.001), the NHB population (p = 0.011), and the Hispanic population (p < 0.015). When looking at each cohort at different points in the recruitment process before and after the intervention, in the Hispanic population, we saw significant increases in the number approached (p < 0.001) and number randomized (p < 0.001) and statistically insignificant increases in the NHB population approached (p = 0.067) and randomized (p = 0.295). Similarly, we saw that the changes in the recruitment letter led to a statistically significant increase in Hispanic recruitment (7.0 to 39.1%, p < 0.001) but not the NHB cohort (19.6 to 35.8%, p < 0.065).

CONCLUSION

This study introduces several culturally sensitive considerations and possible approaches for the design of recruitment materials, addressing mistrust, lack of interest, culture, and communication for use in NHB and Hispanic populations. Similarly, the described microtargeting techniques leverage the technological advancements in cohort building to improve the reach and efficiency of the randomization rate of underrepresented groups thereby enhancing clinical trial diversity.

Centering Diverse Communities within Mindful Parenting Interventions in the U.S.: A Narrative Literature Review

BACKGROUND

While mindfulness-based interventions targeted toward parents (and families) in the U.S. offer promise for the treatment and prevention of youth psychological disorders, current research has established the underrepresentation of diverse participants in the research literature. The full extent of inequalities in the demographics of participation in parent mindfulness intervention is less understood.

OBJECTIVE

This study aimed to utilize a narrative literature review approach to examine and describe the degree to which research on mindful parenting interventions is inclusive of BIPOC (Black, Indigenous, and People of Color) communities, non-clinical samples (no diagnosed disorder), cultural adaptions, and skills specific to parenting.

METHODS

An electronic database search of US-based studies was undertaken for empirical studies that primarily focused on parent mindfulness interventions, which reported outcomes related to either parenting behaviors or child mental health outcomes. After a full-text review, the search resulted in 34 articles. A narrative literature review of the 34 studies was conducted to assess the inclusion of BIPOC communities, non-clinical samples, cultural adaptions, and skills specific to parenting.

RESULTS

This review found notable gaps in the degree to which mindful parenting research (1) included BIPOC populations in study samples; (2) focused on non-clinical samples; (3) adapted interventions to align with the cultural needs of participants; and (4) included the application of mindfulness to enhancing knowledge, skills, and behaviors specific to parenting.

CONCLUSIONS

Given these gaps in the parent mindfulness literature, greater research attention is needed on mindful parenting interventions targeted toward BIPOC communities with no clinical diagnoses, interventions optimized by cultural adaptations, and explicit applications to parenting.

Are Patient-Reported Outcome Measures for Anterior Cruciate Ligament Injuries Validated for Spanish Language and Culture?

Background

Patient-reported outcome measures (PROMs) have been adopted as a way to measure patient self-rated physical function and health status for patients with anterior cruciate ligament (ACL) injuries. Although multiple PROMs exist and have been translated into various languages, the cross-cultural adaptation and validity of these PROMs for Spanish-speaking patients is unknown.

Purpose

To evaluate the adaptation quality and psychometric properties of Spanish-language adaptations of PROMs for patients with ACL injuries.

Study Design

Scoping review; Level of evidence, 3.

Methods

Under PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, we reviewed published studies related to adaptation quality and psychometric properties of Spanish PROMs in patients with ACL injuries. The methodological quality of the included studies was assessed using the Guidelines for the Process of Cross-Cultural Adaptation of Self-Reported Measures, the Quality Criteria for Psychometric Properties of Health Status Questionnaires, and the Consensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. The level of evidence for each PROM was determined based on the number of studies, methodological quality, consistency of results, and sample size.

Results

The initial search strategy identified 5687 articles. After removal of duplicates, 1882 titles were screened, and 114 articles were assessed for eligibility. Six articles were selected for final review, comprising 4 PROMs: the Lysholm knee score, the Anterior Cruciate Ligament-Return to Sport After Injury (ACL-RSI), the Lower Extremity Functional Scale, and the Lower Limb Functional Index. Three studies followed all 6 processes for cross-cultural adaptation. None of the studies demonstrated all 14 domains required for cross-cultural validity (eg, description of translator expertise). The ACL-RSI achieved the highest level of evidence, with 3 of 9 domains demonstrating moderate evidence.

Conclusion

This review identified 4 instruments that have been translated for Spanish-speaking patients with ACL injuries, none of which demonstrated appropriate adaptation or robust psychometric properties. The study highlights the need for improvement in PROMs for Spanish-speaking patients and the potential for mismeasurement and inappropriate application of PROM results in patients with ACL injuries.

Recruitment rates and strategies in exercise trials in cancer survivorship: a systematic review

PURPOSE

Despite clear evidence-based supporting a benefit to exercise on physical and psychological metrics in patients with cancer, recruitment to exercise trials amongst cancer survivors is suboptimal. We explore current recruitment rates, strategies, and common barriers to participation in exercise oncology trials in cancer survivorship.

METHODS

A systematic review was conducted using a pre-defined search strategy in EMBASE, CINAHL, Medline, Cochrane Library, and Web of Science. The search was performed up to 28/02/2022. Screening of titles and abstracts, full-text review, and data extraction was completed in duplicate.

RESULTS

Of the 3204 identified studies, 87 papers corresponding to 86 trials were included. Recruitment rates were highly variable with a median rate of 38% (range 0.52-100%). Trials recruiting prostate cancer patients only had the highest median recruitment rate (45.9%) vs trials recruiting colorectal cancer patients only which had the lowest (31.25%). Active recruitment strategies such as direct recruitment via a healthcare professional were associated with higher recruitment rates (rho = 0.201, p = 0.064). Common reasons for non-participation included lack of interest (46.51%, n (number of studies) = 40); distance and transport (45.3%, n = 39); and failure to contact (44.2%, n = 38).

CONCLUSIONS

Recruitment of cancer survivors to exercise interventions is suboptimal with barriers being predominantly patient-oriented. This paper provides the benchmark for current recruitment rates to exercise oncology trials, providing data for trialists planning future trial design and implementation, optimise future recruitment strategies, and evaluate their own recruitment success against current practice.

IMPLICATIONS FOR CANCER SURVIVORS

Enhanced recruitment to cancer survivorship exercise trials is necessary in facilitating the publication of definitive exercise guidelines, generalisable to varying cancer cohorts.

Cardiovascular Events, Malignancies, and Efficacy Outcomes in Latin American Patients With Rheumatoid Arthritis Receiving Tofacitinib or Tumor Necrosis Factor Inhibitors: A Post Hoc Analysis of the ORAL Surveillance Study

BACKGROUND/OBJECTIVE

To assess safety/efficacy of tofacitinib and tumor necrosis factor inhibitors (TNFi) in patients from Latin America (LATAM) in ORAL Surveillance.

METHODS

In ORAL Surveillance, 4362 patients with rheumatoid arthritis aged ≥50 years with ≥1 additional cardiovascular risk factor received tofacitinib 5 or 10 mg twice daily or TNFi. This post hoc analysis stratified patients by geographical location (LATAM, n = 1202; non-LATAM, n = 3160). Incidence rates (IRs; patients with first event/100 patient-years) and hazard ratios for adverse events of special interest were reported. Efficacy outcomes included Clinical Disease Activity Index and American College of Rheumatology 20/50/70 responses.

RESULTS

Risk factors associated with cardiovascular disease and malignancies were less prevalent in the LATAM cohort compared with the non-LATAM cohort. IRs for patients receiving tofacitinib (combined doses) versus TNFi were 0.54 versus 0.28 (LATAM) and 1.14 versus 0.92 (non-LATAM) for major adverse cardiovascular events; 0.58 versus 0.27 (LATAM) and 1.33 versus 0.95 (non-LATAM) for malignancies excluding nonmelanoma skin cancer; and 0.69 versus 0.35 (LATAM) and 0.63 versus 0.33 (non-LATAM) for all-cause death. IRs for nonmelanoma skin cancer and venous thromboembolism were also numerically higher with tofacitinib versus TNFi and in the non-LATAM cohort versus LATAM. Efficacy was similar across treatment groups within each cohort.

CONCLUSIONS

Adverse events of special interest were generally less frequent in LATAM versus non-LATAM patients, reflecting differences in baseline characteristics, and higher with tofacitinib versus TNFi in both cohorts, consistent with the overall findings of ORAL Surveillance. Our findings emphasize the importance of assessing individual risk factors to guide benefit/risk assessment and treatment decisions.

Tailored approach to participant recruitment and retention to maximize health equity in pediatric cancer research

BACKGROUND

Lack of diversity in participants throughout the research process limits the generalizability of findings and may contribute to health disparities. There are unique challenges to recruitment of families to pediatric cancer research studies, especially for those from disadvantaged backgrounds. Thus, there is a need to evaluate the most effective recruitment and retention strategies to optimize equitable recruitment of diverse participants.

METHODS

The present study adapted and implemented methods outlined previously in the literature. These previous efforts were developed to address barriers to pediatric research, behavioral health intervention research and research with Black adolescents. Recruitment and retention strategies are described across four different time points: pre-approach, initial connection, building connection and follow-up. Eligible families of children with a pediatric cancer diagnosis were approached during a routine oncology visit. Once consented, enrollment and retention rates over three timepoints of data collection were recorded and evaluated.

RESULTS

Results indicated high rates of enrollment (86%) and retention (95%) for eligible participants. There were no trends in heightened attrition for any specific subgroup.

CONCLUSIONS

The findings of this study are promising and suggest these recruitment and retention strategies may be useful in recruiting individuals from disadvantaged backgrounds.

Core socioDemographic data variables in ICU Trials (CoDe-IT): a protocol for generating core data variables using a Delphi consensus process

INTRODUCTION

Sociodemographic variables influence health outcomes, either directly (ie, gender identity) or indirectly (eg, structural/systemic racism based on ethnoracial group). Identification of how sociodemographic variables can impact the health of critically ill adults is important to guide care and research design for this population. However, despite the growing recognition of the importance of collecting sociodemographic measures that influence health outcomes, insufficient and inconsistent data collection of sociodemographic variables persists in critical care studies. We aim to develop a set of core data variables (CoDaV) for social determinants of health specific to studies involving critically ill adults.

METHODS AND ANALYSIS

We will conduct a scoping review to generate a list of possible sociodemographic measures to be used for round 1 of the modified Delphi processes. We will engage relevant knowledge users (previous intensive care unit patients and family members, critical care researchers, critical care clinicians and research co-ordinators) to participate in the modified Delphi consensus survey to identify the CoDaV. A final consensus meeting will be held with knowledge user representatives to discuss the final CoDaV, how each sociodemographic variable will be collected (eg, level of granularity) and how to disseminate the CoDaV for use in critical care studies.

Testing the effectiveness of the culturally adapted skills training START NOW to reduce mental health problems in adolescent refugees: study protocol for a randomized controlled trial

Background

Adolescent refugees are particularly vulnerable to mental health problems, as they experience many risk factors associated with their resettlement at crucial stages of their physical and emotional development. However, despite having a greater healthcare needs than others, they face significant barriers to accessing healthcare services. Therefore, this study aims to test the effectiveness of a low-threshold, culturally adapted version of the skills training START NOW - START NOW Adapted - in reducing mental health problems among adolescent refugees.

Methods

We will recruit 80 adolescent refugees (15-18 years) with symptoms of anxiety and depression or high perceived stress in Northwestern Switzerland. They will be randomly assigned to one of two study groups: an intervention group, receiving START NOW Adapted, and a control group, receiving treatment as usual (TAU). The intervention will last 10 weeks and will consist of one-hour sessions per week provided by a trained facilitator with the same cultural background, in the respective language. Assessments to collect depressive and anxious symptoms, perceived stress, social-ecological resilience, and emotion recognition abilities will be conducted pre-intervention, post-intervention (11 weeks later) and at the 3-month follow-up. Multilevel models will be computed with primary and secondary outcome measures as dependent variables. An effect of at least moderate size will be considered clinically relevant.

Discussion

This randomized controlled trial aims to investigate the effectiveness of a culturally adapted version of START NOW, providing valuable insights to improve current health promotion for adolescent refugees in Switzerland (or rather lack thereof). Ultimately, the effects of START NOW may facilitate integration and promote healthy development while decreasing costs associated with treating migration- or conflict-related trauma.Clinical trial registration: ClinicalTrials.gov, identifier: NCT06324864.

The Impact of Insider Researcher Trainees in Recruiting and Retaining Latinx in an Outdoor Health Promotion Research Study

Latinx represent the second largest ethnic group in the USA and remain significantly underrepresented in research studies. Efforts to better include Latinx make use of community-engaged research (CEnR) approaches, peer-navigators, and cultural humility training for research teams. While these efforts have led to slight increases in Latinx participation, studies to identify strategic practices for better inclusion of Latinx participants are needed. The objective of this study was to qualitatively examine factors leading to successful recruitment and retention of Latinx participants in the Promoting Activity and Stress Reduction in the Outdoors (PASITO) intervention. For this intervention, 99 low-income Latinx clients in a local community were contacted and 52 participants were recruited (53%). All were retained in the 3-month intervention. Of these, 12 were interviewed within 6 months of the close of PASITO by bi-cultural and bi-lingual non-research staff. They conducted one-on-one structured telephone interviews. Of the twelve participants, three (25%) were men, nine (75%) were women, and the mean age was 43.7 (SD = 8.7). Four critical themes for the recruitment and retention of Latinx populations emerged from the interviews: (1) importance of insider researchers; (2) sense of community and belonging; (3) responsive programming; and (4) health-promoting activities. These findings support the significant role insider researchers can play, and social identity theory provides a useful framework for understanding the role of insider researchers in recruiting and retaining Latinx, and likely other minoritized groups, in clinical studies. Insider researchers possess the skills, training, community cultural wealth, in-depth understanding of their communities, and structural competencies that position them to carry out more inclusive studies to address the needs of marginalized communities and advance science.

Why Did Our Trial Not Work Out? A Qualitative Analysis

Background

An online self-help programme for the treatment of depression called Hap-pas-Hapi was tested among Albanian-speaking immigrants in Switzerland and Germany, and two different levels of cultural adaptation were compared. Despite a massive recruitment effort, an insufficient number of participants could be recruited, and the drop-out rate was over 90%.

Aims

We conducted a qualitative study to better understand the reasons for the non-use of Hap-pas-Hapi.

Method

Eleven interviews were conducted with 17 Albanian-speaking participants aged 19-59. Participants were recruited for the purpose of this study and were not participants from the trial. They went through the recruitment material and the Hap-pas-Hapi introduction module, commented on the graphic design, usability, content, and shared their views about mental health and self-help.

Results

Participants criticised the lack of a "design system" (i.e., a clearly identifiable and consistent graphic design) on social media for Hap-pas-Hapi, and the recruitment messages were unclear. The programme itself was perceived to be important and helpful for the community at large, but most participants said that they would not use it for themselves. The younger generation would have preferred an application in German or French, while the older generation did not see a benefit in using an online self-help programme to manage their psychological distress. Negative beliefs about mental disorders and psychological interventions were perceived to be common in this target group.

Discussion

A professional recruitment strategy, a more careful selection of the target population (e.g., age groups) and different kinds of adaptations might have resulted in a better acceptance of the intervention. At the same time, anti-stigma campaigns and psychoeducation are needed to enhance treatment motivation.

Effect of Cultural Adaptation of a Smartphone-Based Self-Help Programme on Its Acceptability and Efficacy: Randomized Controlled Trial

Background

Research on cultural adaptation of psychological interventions indicates that a higher level of adaptation is associated with a higher effect size of the intervention. However, direct comparisons of different levels of adaptations are scarce.

Aims

This study used a smartphone-based self-help programme called Step-by-Step (Albanian: Hap-pas-Hapi) for the treatment of psychological distress among Albanian-speaking immigrants in Switzerland and Germany. Two levels of cultural adaptation (i.e., surface vs. deep structure adaptation) were compared. We hypothesised that the deep structure adaptation would enhance the acceptance and efficacy of the intervention.

Method

We conducted a two-arm, single-blind randomised controlled trial. Inclusion criteria were good command of the Albanian language, age above 18, and elevated psychological distress (Kessler Psychological Distress Scale score above 15). Primary outcome measures were the total score of the Hopkins Symptom Checklist and the number of participants who completed at least three (out of five) sessions. Secondary outcomes were global functioning, well-being, post-traumatic stress, and self-defined problems.

Results

Two-hundred-twenty-two participants were included, of which 18 (8%) completed the post-assessments. The number of participants who completed the third session was equal in both conditions, with N = 5 (5%) and N = 6 (6%) respectively.

Discussion

Drop-out rates were high in both conditions, and no group difference was found regarding the acceptance of the intervention. The high drop-out rate stands in contrast with other trials testing Step-by-Step. Future research should examine cultural factors impacting recruitment strategies, as insights could help to reduce participant drop-out rates in clinical trials.

NIHR Race Equality Framework: development of a tool for addressing racial equality in public involvement

BACKGROUND

While there has been a long recognition of the importance of race equality in health and care research, there is a lack of sustained action among research funding and research performing organisations to address racial equality in public involvement. This paper describes how the UK's National Institute for Health and Care Research (NIHR) convened a Race Equality Public Action Group (REPAG), which co-developed with public contributors and stakeholders a Race Equality Framework - a tool for addressing racial equality in public involvement.

METHODS

The REPAG, through meetings and discussions, defined the focus of the Framework, and developed an initial draft of the Framework. Public contributors identified the need for broader consultation with other public members. Three community consultation events with a total of 59 members of Black African-, Asian- and Caribbean-heritage communities were held to seek their views on health and care research generally and on the draft Framework specifically. The draft Framework was modified and piloted among 16 organisations delivering health and care research. Following feedback from the pilot, the Framework was modified and prepared for publication.

RESULTS

The Framework is designed as a self-assessment tool comprised of 50 questions pertaining to five domains of organisational activity: 1) individual responsibility, 2) leadership, 3) public partnerships, 4) recruitment, and 5) systems and processes. The questions were co-designed with REPAG public members and provide key concepts and elements of good practice that organisations should consider and address on their path to achieving racial competence. The accompanying materials provide implementation guidance with 20 detailed steps, case studies of actions taken in seven pilot organisations, and links to additional resources. The pilot demonstrated the feasibility of conducting a meaningful self-assessment over a period of three months and the usefulness of the results for developing longer-term action plans.

CONCLUSION

The Framework represents the first self-assessment tool for addressing racial equality in public involvement. Co-design with REPAG public members enhanced its authenticity and practicality. Organisations in the field of health and care research and any other organisations that use partnerships with the public are encouraged to adopt the Framework.

The Role of Patient-Reported Experience and Outcome Measures in Kidney Health Equity-Oriented Quality Improvement

Risk, prevalence, management, and outcomes in chronic kidney disease (CKD) are influenced by social and broader determinants of health. Consequently, there are wide-ranging kidney health inequities. As patients are key stakeholders, their perspectives on the care they receive and on health status are central in guiding health system improvement, particularly to reduce the impact of disadvantage. Patient-reported experience measures (PREMs) and patient-reported outcome measures (PROMs) are important self-report tools in quality improvement, acting to guide initatives aimed at enhancing access to timely and relevant support. However, the extent to which PREMs and PROMs address the reduction of kidney health inequities is unclear. The aim of this review is to summarize how PREMs and PROMs are designed and implemented, highlighting key dimensions that are integral to health equity-oriented quality improvement in kidney care. There are several problems yet to be overcome so that such tools do not unintentionally reproduce kidney health gaps. Inclusive generation of the scope of tools, transparent reporting on attributes of patients who engage, and embedding PREMs and PROMs within a framework of value-based quality improvement is fundamental to their impact as part of equitable health system transformation.

Shining a spotlight on the inclusion of disabled participants in clinical trials: a mixed methods study

BACKGROUND

It is crucial to include a wide range of the population in clinical trials for the outcome to be applicable in real-world settings. Existing literature indicates that under-served groups, including disabled people, have been excluded from participating in clinical trials without justification. Exclusion from clinical trials exacerbates disparities in healthcare and diminishes the benefits for excluded populations. Therefore, this study was conducted to investigate potential obstacles that prevent disabled people from participating in clinical trials in the United Kingdom (UK).

METHODS

The study was carried out through an explanatory sequential mixed methods design. The Imperial Clinical Trials Unit devised and implemented an online questionnaire-based survey (with open/closed-ended questions) and an online focus group discussion. The target population were disabled people, family members/carers of disabled people and staff involved in clinical trials, whereupon the sample was recruited by convenience sampling methods via posters and emails through various networks. The Qualtrics XM survey system was used as the host platform for the online survey, and Microsoft Teams was used for an online focus group discussion. The focus group discussion was conducted to gain a deeper understanding of the themes identified from the survey responses. We analysed responses to the survey via descriptive analysis and used thematic analysis to synthesise the free-text answers from the survey and focus group discussion.

RESULTS

We received 45 responses to the survey questionnaire and 5 disabled people took part in a focus group discussion. Our findings highlighted the differences between the perspectives of researchers and those "being researched" and different types of barriers experienced by disabled people: opportunity barriers (inadequate recruitment strategy and ambiguous eligibility criteria), awareness barriers (perception of disability) and acceptance/refusal barriers (available support and adjustment, and sharing of trial results).

CONCLUSION

Our findings support perspectives drawn from the Ford Framework regarding the need to consider all barriers, not just up to the point of enrolment into trials but also beyond the point of inclusion in clinical trials. We support calls for the introduction of legislation on including disabled people in clinical trials, implementation of industry/community-wide participatory approaches and the development of guidelines, a combined public-private approach.

Email-Based Recruitment Into the Health eHeart Study: Cohort Analysis of Invited Eligible Patients

BACKGROUND

Web- or app-based digital health studies allow for more efficient collection of health data for research. However, remote recruitment into digital health studies can enroll nonrepresentative study samples, hindering the robustness and generalizability of findings. Through the comprehensive evaluation of an email-based campaign on recruitment into the Health eHeart Study, we aim to uncover key sociodemographic and clinical factors that contribute to enrollment.

OBJECTIVE

This study sought to understand the factors related to participation, specifically regarding enrollment, in the Health eHeart Study as a result of a large-scale remote email recruitment campaign.

METHODS

We conducted a cohort analysis on all invited University of California, San Francisco (UCSF) patients to identify sociodemographic and clinical predictors of enrollment into the Health eHeart Study. The primary outcome was enrollment, defined by account registration and consent into the Health eHeart Study. The email recruitment campaign was carried out from August 2015 to February 2016, with electronic health record data extracted between September 2019 and December 2019.

RESULTS

The email recruitment campaign delivered at least 1 email invitation to 93.5% (193,606/206,983) of all invited patients and yielded a 3.6% (7012/193,606) registration rate among contacted patients and an 84.1% (5899/7012) consent rate among registered patients. Adjusted multivariate logistic regression models analyzed independent sociodemographic and clinical predictors of (1) registration among contacted participants and (2) consent among registered participants. Odds of registration were higher among patients who are older, women, non-Hispanic White, active patients with commercial insurance or Medicare, with a higher comorbidity burden, with congestive heart failure, and randomized to receive up to 2 recruitment emails. The odds of registration were lower among those with medical conditions such as dementia, chronic pulmonary disease, moderate or severe liver disease, paraplegia or hemiplegia, renal disease, or cancer. Odds of subsequent consent after initial registration were different, with an inverse trend of being lower among patients who are older and women. The odds of consent were also lower among those with peripheral vascular disease. However, the odds of consent remained higher among patients who were non-Hispanic White and those with commercial insurance.

CONCLUSIONS

This study provides important insights into the potential returns on participant enrollment when digital health study teams invest resources in using email for recruitment. The findings show that participant enrollment was driven more strongly by sociodemographic factors than clinical factors. Overall, email is an extremely efficient means of recruiting participants from a large list into the Health eHeart Study. Despite some improvements in representation, the formulation of truly diverse studies will require additional resources and strategies to overcome persistent participation barriers.

Representation of ethnic and racial minority groups in European vaccine trials: a quantitative analysis of clinical trials registries

Objectives

The representation of ethnic minority groups in European vaccine trials is an important and hitherto unaddressed gap in the literature. The objectives of this study were to determine the proportion of European vaccine trials that report data on the ethnic demographics of participants, to evaluate the distribution of ethnic minority groups among trial participants (where reported), and ascertain whether this is representative of the wider population of the country.

Design

We evaluated the representation of ethnic/racial minority groups in clinical research, conducting a quantitative analysis of clinical trials registry data from completed vaccine trials in Europe that commenced between 1 January 2010 and 31 December 2020.

Data sources

Data were collected from four major clinical trial databases: ClinicalTrials.gov, the European Union Clinical Trials Register (EUCTR), the International Standard Randomised Controlled Trial Number (ISRCTN) and the International Clinical Trials Registry Platform (ICTRP).

Results

A majority of clinical trials failed to either record or report the race/ethnicity of their volunteers on the clinical trials registry databases. Reported participants in UK vaccine trials were not representative of the ethnic demographics of the wider population. Unavailability of population-level ethnicity data for many European countries was a significant barrier to determining the wider applicability of these findings.

Conclusions

Under-representation of ethnic minority groups in vaccine trials may have implications for the effectiveness of routine vaccinations, threatening the principles of justice and equity that are embedded in national medical research guidelines. Unavailability of population-level ethnicity data exacerbates the prevailing lack of understanding of the extent of this issue, despite literature indicating cause for concern.

Expectation of clinical decision support systems: a survey study among nephrologist end-users

BACKGROUND

Chronic kidney disease (CKD), a major public health problem with differing disease etiologies, leads to complications, comorbidities, polypharmacy, and mortality. Monitoring disease progression and personalized treatment efforts are crucial for long-term patient outcomes. Physicians need to integrate different data levels, e.g., clinical parameters, biomarkers, and drug information, with medical knowledge. Clinical decision support systems (CDSS) can tackle these issues and improve patient management. Knowledge about the awareness and implementation of CDSS in Germany within the field of nephrology is scarce.

PURPOSE

Nephrologists' attitude towards any CDSS and potential CDSS features of interest, like adverse event prediction algorithms, is important for a successful implementation. This survey investigates nephrologists' experiences with and expectations towards a useful CDSS for daily medical routine in the outpatient setting.

METHODS

The 38-item questionnaire survey was conducted either by telephone or as a do-it-yourself online interview amongst nephrologists across all of Germany. Answers were collected and analysed using the Electronic Data Capture System REDCap, as well as Stata SE 15.1, and Excel. The survey consisted of four modules: experiences with CDSS (M1), expectations towards a helpful CDSS (M2), evaluation of adverse event prediction algorithms (M3), and ethical aspects of CDSS (M4). Descriptive statistical analyses of all questions were conducted.

RESULTS

The study population comprised 54 physicians, with a response rate of about 80-100% per question. Most participants were aged between 51-60 years (45.1%), 64% were male, and most participants had been working in nephrology out-patient clinics for a median of 10.5 years. Overall, CDSS use was poor (81.2%), often due to lack of knowledge about existing CDSS. Most participants (79%) believed CDSS to be helpful in the management of CKD patients with a high willingness to try out a CDSS. Of all adverse event prediction algorithms, prediction of CKD progression (97.8%) and in-silico simulations of disease progression when changing, e. g., lifestyle or medication (97.7%) were rated most important. The spectrum of answers on ethical aspects of CDSS was diverse.

CONCLUSION

This survey provides insights into experience with and expectations of out-patient nephrologists on CDSS. Despite the current lack of knowledge on CDSS, the willingness to integrate CDSS into daily patient care, and the need for adverse event prediction algorithms was high.

The importance of diversity in clinical research

Clinical research is a fundamental part of the healthcare system and is critical to improving care, making it safe and effective. Research participants should be diverse as this reduces bias and helps to better understand illness and treatment and how it affects different groups of people. However, due to health inequalities and barriers to research participation, clinical research still lacks diversity. Data from the US Food and Drug Administration showed that 76% of research participants were White and the remaining 24% were from an ethnic minority. In the UK, only 5% of ethnic minorities have ever participated in clinical trials. Recently, with the COVID-19 vaccine trials, out of 270 000 participants, only 11 000 and 1200 participants were from Asian and Black backgrounds, respectively. The research participation of under-represented groups requires co-development with community members. This proactive approach helps establish trust and enhance recruitment strategies that build a positive legacy for under-represented groups.

Investigating the impact of fluid status on the ultrasound assessment of muscle quantity and quality in the diagnosis of sarcopenia - a multidimensional cross-sectional study

BACKGROUND

Sarcopenia is a clinical manifestation of adverse ageing, characterised by progressive loss of muscle mass and function. Diagnosis requires assessment of muscle quantity and quality; ultrasound represents an emerging tool for this. However, ultrasound muscle assessment may be impacted by fluid balance. This is particularly important when assessing for acute sarcopenia in hospitalised patients, where fluid disturbance often occurs. The primary aim of this study was to characterise the impact of fluid status on ultrasound muscle assessment, such that this may be accounted for in sarcopenia diagnostics.

METHODS

This Multidimensional Cross-sectional study involved 80 participants, who were inpatients at QEHB, a large UK tertiary centre. Fluid status was evaluated clinically and quantified using Bioelectrical Impedance Analysis (BIA). Muscle quantity was measured using Bilateral Anterior Thigh Thickness (BATT) with Rectus Femoris (RF) echogenicity used to assesses muscle adiposity and hence provide an inverse measure of muscle quality.

RESULTS

A significant positive correlation was found between fluid status, measured using BIA, and BATT as a measure of muscle quantity, in males (rs = 0.662, p < 0.001) and females (rs = 0.638, p < 0.001). A significant negative correlation was found between fluid status and RF echogenicity (rs=-0.448, p < 0.001).

CONCLUSIONS

These findings demonstrate associations between fluid balance and ultrasound assessment of muscle quantity and quality. Given the emerging use of ultrasound muscle assessment in sarcopenia diagnosis, there is a need to account for this in clinical practice. Future research should focus on the development of a corrective equation allowing assessment of muscle quantity and quality which account for changes in fluid status, hence aiding accurate diagnosis of sarcopenia.

Medication Adherence in Elderly Diabetic Patients: A Cross-Sectional Study From Dakshina Kannada, India

Diabetes Mellitus (DM) has emerged as a major global healthcare problem. The risk of diabetes can be reduced by maintaining blood glycaemic levels, which can be achieved by stringent adherence to the treatment regime. Therefore, there is a continuing need to assess the level of adherence to medication/self-care activities and the factors that are related to non-adherence to medication and self-care. This would facilitate healthcare professionals to identify subjects with low medication adherence and thereby aid them in planning interventions to improve medication and self-care adherence. In this study, we aimed to estimate the proportion of medication adherence among diabetic patients above 60 years of age attending a tertiary care hospital in Southern India. We found that 72% of type 2 diabetes patients were adherent to the medications prescribed to them and there was a discernible effect of gender and literacy on medication adherence. However, more such regional studies need to be conducted with a larger sample size from diverse hospital setups to obtain a clear and unbiased picture of the drug adherence scenario in India.

Are Patient-Reported Outcome Measures for Distal Radius Fractures Validated for Spanish and Culture? A Systematic Review

PURPOSE

Patient-reported outcome measures (PROMs) are used commonly to assess function to direct treatment and evaluate outcomes for patients with distal radius fractures. Most PROMs have been developed and validated in English with minimal report of the demographics of patients studied. The validity of applying these PROMs among Spanish-speaking patients is unknown. The purpose of this study was to evaluate the quality and psychometric properties of Spanish-language adaptations of PROMs for distal radius fractures.

METHODS

We conducted a systematic review to identify published studies of adaptations of Spanish-language PROMs evaluating patients with distal radius fractures. We evaluated the methodologic quality of the adaptation and validation using Guidelines for the Process of Cross-Cultural Adaptation of Self-Report Measures, Quality Criteria for Psychometric Properties of Health Status Questionnaire, and the Consensus-based Standards for the Selection of Health Measurement Instruments Checklist for Cross-Cultural Validity. The level of evidence was evaluated based upon prior methodology.

RESULTS

Five instruments reported in eight studies were included: the Patient-Rated Wrist Evaluation (PRWE), Disability of Arm Shoulder and Hand, Upper Limb Functional Index, Lawton Instrumental Activities of Daily Living Scale, and Short Musculoskeletal Function Assessment. The PRWE was the most frequently included PROM. No study followed all six processes for adaptation or assessed all measurement properties. No study demonstrated the completion of more than eight of the 14 aspects of cross-cultural validity. The PRWE had moderate evidence to support half of the domains of measurement properties evaluating the level of evidence.

CONCLUSIONS

None of the five instruments identified received a good rating on all three checklists. Only the PWRE demonstrated moderate evidence on half of the measurement domains.

CLINICAL RELEVANCE

Given the lack of strong evidence to support the quality of these instruments, we recommend adaptation and testing of PROMs for this population before use. Currently, PROMs in Spanish-speaking patients should be used with caution so as not to perpetuate health care disparities.

The effect of a novel, digital physical activity and emotional well-being intervention on health-related quality of life in people with chronic kidney disease: trial design and baseline data from a multicentre prospective, wait-list randomised controlled trial (kidney BEAM)

BACKGROUND

Physical activity and emotional self-management has the potential to enhance health-related quality of life (HRQoL), but few people with chronic kidney disease (CKD) have access to resources and support. The Kidney BEAM trial aims to evaluate whether an evidence-based physical activity and emotional wellbeing self-management programme (Kidney BEAM) leads to improvements in HRQoL in people with CKD.

METHODS

This was a prospective, multicentre, randomised waitlist-controlled trial, with health economic analysis and nested qualitative studies. In total, three hundred and four adults with established CKD were recruited from 11 UK kidney units. Participants were randomly assigned to the intervention (Kidney BEAM) or a wait list control group (1:1). The primary outcome was the between-group difference in Kidney Disease Quality of Life (KDQoL) mental component summary score (MCS) at 12 weeks. Secondary outcomes included the KDQoL physical component summary score, kidney-specific scores, fatigue, life participation, depression and anxiety, physical function, clinical chemistry, healthcare utilisation and harms. All outcomes were measured at baseline and 12 weeks, with long-term HRQoL and adherence also collected at six months follow-up. A nested qualitative study explored experience and impact of using Kidney BEAM.

RESULTS

340 participants were randomised to Kidney BEAM (n = 173) and waiting list (n = 167) groups. There were 96 (55%) and 89 (53%) males in the intervention and waiting list groups respectively, and the mean (SD) age was 53 (14) years in both groups. Ethnicity, body mass, CKD stage, and history of diabetes and hypertension were comparable across groups. The mean (SD) of the MCS was similar in both groups, 44.7 (10.8) and 45.9 (10.6) in the intervention and waiting list groups respectively.

CONCLUSION

Results from this trial will establish whether the Kidney BEAM self management programme is a cost-effective method of enhancing mental and physical wellbeing of people with CKD.

Reporting demographics in randomized control trials in spine surgery - we must do better

BACKGROUND CONTEXT

Demographic factors contribute significantly to spine surgery outcomes. Although race and ethnicity are not proxies for disease states, the intersection between these patient characteristics and socioeconomic status significantly impact patient outcomes.

PURPOSE

The purpose of this study is to investigate the frequency of demographic reporting and analysis in randomized controlled clinical trials (RCTs) published in the three highest impact spine journals.

STUDY DESIGN

Systematic review.

PATIENT SAMPLE

We analyzed 278 randomized control trials published in The Spine Journal, Spine, and Journal of Neurosurgery: Spine between January 2012 - January 2022.

OUTCOME MEASURES

Extracted manuscript characteristics included the frequency of demographic reporting, sample size, and demographic composition of studies.

METHODS

We conducted a systematic review of RCTs published between January 2012 - January 2022 in the three highest impact factor spine journals in 2021: The Spine Journal, Spine, and Journal of Neurosurgery: Spine. We determined if age, gender, BMI, race, and ethnicity were reported and analyzed for each study. The overall frequency of demographic reporting was assessed, and the reporting trends were analyzed for each individual year and journal. Among studies that did report demographics, the populations were analyzed in comparison to the national population per United States (US) census reports. Studies were evaluated for bias using Cochrane risk-of-bias.

RESULTS

Our search identified 278 RCTs for inclusion. 166 were published in Spine, 65 in The Spine Journal, and 47 in Journal of Neurosurgery: Spine. Only 9.35% (N=26) and 3.9% (N=11) of studies reported race and ethnicity, respectively. Demographic reporting frequency did not vary based on the publishing journal. Reporting of age and BMI increased over time, but reporting of race and ethnicity did not. Among RCTs that reported race, 88% were conducted in the US, and 85.71% of the patients in these US studies were White. White subjects were overly represented compared to the US population (85.71% vs. 61.63%, p<.001), and non-White or Black patients were most underrepresented (2.89% vs. 25.96%, p<.001).

CONCLUSIONS

RCTs published in the three highest impact factor spine journals failed to frequently report patient race or ethnicity. Among studies published in the US, study populations are increasingly represented by non-Hispanic White patients. As we strive to care for an increasingly diverse population and reduce disparities to care, spine surgeons must do a better job reporting these variables to increase the external validity and generalizability of RCTs.

Translating Cultural Safety to the UK

Disproportional morbidity and mortality experienced by ethnic minorities in the UK have been highlighted by the COVID-19 pandemic. The 'Black Lives Matter' movement has exposed structural racism's contribution to these health inequities. 'Cultural Safety', an antiracist, decolonising and educational innovation originating in New Zealand, has been adopted in Australia. Cultural Safety aims to dismantle barriers faced by colonised Indigenous peoples in mainstream healthcare by addressing systemic racism.This paper explores what it means to be 'culturally safe'. The ways in which New Zealand and Australia are incorporating Cultural Safety into educating healthcare professionals and in day-to-day practice in medicine are highlighted. We consider the 'nuts and bolts' of translating Cultural Safety into the UK to reduce racism within healthcare. Listening to the voices of black, Asian and minority ethnic National Health Service (NHS) consumers, education in reflexivity, both personal and organisational within the NHS are key. By listening to Indigenous colonised peoples, the ex-Empire may find solutions to health inequity. A decolonising feedback loop is required; however, we should take care not to culturally appropriate this valuable reverse innovation.

Identification and Management of Atherosclerotic Cardiovascular Disease Risk in South Asian Populations in the U.S

South Asians (SAs, individuals with ancestry from Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan, and Sri Lanka) are among the fastest growing ethnic subgroups in the United States. SAs typically experience a high prevalence of diabetes, abdominal obesity, and hypertension, among other cardiovascular disease risk factors, which are often under recognized and undermanaged. The excess coronary heart disease risk in this growing population must be critically assessed and managed with culturally appropriate preventive services. Accordingly, this scientific document prepared by a multidisciplinary group of clinicians and investigators in cardiology, internal medicine, pharmacy, and SA-centric researchers describes key characteristics of traditional and nontraditional cardiovascular disease risk factors, compares and contrasts available risk assessment tools, discusses the role of blood-based biomarkers and coronary artery calcium to enhance risk assessment and prevention strategies, and provides evidenced-based approaches and interventions that may reduce coronary heart disease disparities in this higher-risk population.

Community engagement and clinical trial diversity: Navigating barriers and co-designing solutions-A report from the "Health Equity through Diversity" seminar series

INTRODUCTION

In recent years, there has been increasing awareness of the lack of diversity among clinical trial participants. Equitable representation is key when testing novel therapeutic and non-therapeutic interventions to ensure safety and efficacy across populations. Unfortunately, in the United States (US), racial and ethnic minority populations continue to be underrepresented in clinical trials compared to their White counterparts.

METHODS

Two webinars in a four-part series, titled "Health Equity through Diversity," were held to discuss solutions for advancing health equity through diversifying clinical trials and addressing medical mistrust in communities. Each webinar was 1.5 hours long, beginning with panelist discussions followed by breakout rooms where moderators led discussions related to health equity and scribes recorded each room's conversations. The diverse groups of panelists included community members, civic representatives, clinician-scientists, and biopharmaceutical representatives. Scribe notes from discussions were collected and thematically analyzed to uncover the central themes.

RESULTS

The first two webinars were attended by 242 and 205 individuals, respectively. The attendees represented 25 US states, four countries outside the US, and shared various backgrounds including community members, clinician/researchers, government organizations, biotechnology/biopharmaceutical professionals, and others. Barriers to clinical trial participation are broadly grouped into the themes of access, awareness, discrimination and racism, and workforce diversity. Participants noted that innovative, community-engaged, co-designed solutions are essential.

CONCLUSIONS

Despite racial and ethnic minority groups making up nearly half of the US population, underrepresentation in clinical trials remains a critical challenge. The community engaged co-developed solutions detailed in this report to address access, awareness, discrimination and racism, and workforce diversity are critical to advancing clinical trial diversity.

Optimizing Equity: Working towards Fair Machine Learning Algorithms in Laboratory Medicine

BACKGROUND

Methods of machine learning provide opportunities to use real-world data to solve complex problems. Applications of these methods in laboratory medicine promise to increase diagnostic accuracy and streamline laboratory operations leading to improvement in the quality and efficiency of healthcare delivery. However, machine learning models are vulnerable to learning from undesirable patterns in the data that reflect societal biases. As a result, irresponsible application of machine learning may lead to the perpetuation, or even amplification, of existing disparities in healthcare outcomes.

CONTENT

In this work, we review what it means for a model to be unfair, discuss the various ways that machine learning models become unfair, and present engineering principles emerging from the field of algorithmic fairness. These materials are presented with a focus on the development of machine learning models in laboratory medicine.

SUMMARY

We hope that this work will serve to increase awareness, and stimulate further discussion, of this important issue among laboratorians as the field moves forward with the incorporation of machine learning models into laboratory practice.

Confronting racially exclusionary practices in the acquisition and analyses of neuroimaging data

Across the brain sciences, institutions and individuals have begun to actively acknowledge and address the presence of racism, bias, and associated barriers to inclusivity within our community. However, even with these recent calls to action, limited attention has been directed to inequities in the research methods and analytic approaches we use. The very process of science, including how we recruit, the methodologies we utilize and the analyses we conduct, can have marked downstream effects on the equity and generalizability of scientific discoveries across the global population. Despite our best intentions, the use of field-standard approaches can inadvertently exclude participants from engaging in research and yield biased brain-behavior relationships. To address these pressing issues, we discuss actionable ways and important questions to move the fields of neuroscience and psychology forward in designing better studies to address the history of exclusionary practices in human brain mapping.

Distributional Cost-Effectiveness Analysis of Health Technologies: Data Requirements and Challenges

Governments and health technology assessment agencies are putting greater focus on and efforts in understanding and addressing health inequities. Cost-effectiveness analyses are used to evaluate the costs and health gains of different interventions to inform the decision-making process on funding of new treatments. Distributional cost-effectiveness analysis (DCEA) is an extension of cost-effectiveness analysis that quantifies the equity impact of funding new treatments. Key challenges for the routine and consistent implementation of DCEA are the lack of clearly defined equity concerns from decision makers and endorsed measures to define equity subgroups and the availability of evidence that allows analysis of differences in data inputs associated with the equity characteristics of interest. In this article, we detail the data gaps and challenges to build robust DCEA analysis routinely in health technology assessment and suggest actions to overcome these hurdles.

Pathways Linking Housing Inequalities and Health Outcomes among Migrant and Refugee Populations in High-Income Countries: A Protocol for a Mixed-Methods Systematic Review

Several high-income countries are currently experiencing an unprecedented and multifaceted housing crisis. The crisis is escalating rapidly, and its negative ramifications are shared disproportionately by migrant and refugee communities. Although housing is often cited as an important social determinant of health, the relationship between housing inequalities and health outcomes in the context of migrant and refugee populations remain under-explored, particularly in high-income countries. This paper presents a protocol for a mixed-methods systematic review which will synthesize the evidence on the key housing and health inequalities faced by migrant and refugee populations in high-income countries. It will inform the identification of pathways linking housing inequalities to health outcomes. The protocol for this systematic review was developed with guidance from the Joanna Briggs Institute (JBI) methodology for mixed-methods systematic reviews using a convergent integrated approach to synthesis and integration, and the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) statement. Quantitative, qualitative and mixed-methods studies reporting the association of housing inequalities with physical and mental health outcomes among refugee and migrant populations in high-income countries will be included. Medline, Web of Science, Embase, PsycINFO, Scopus and CINAHL will be searched for peer-reviewed literature. This will be supplemented by gray literature searches using Google Scholar, MedNar and WHOLIS. Two reviewers will independently screen and select studies, assess the methodological quality and conduct data extraction. This systematic review will elucidate the different pathways linking housing inequalities and health outcomes, which may guide the development of targeted housing and public health interventions to improve the health and wellbeing of migrant and refugee populations. The review is registered with PROSPERO (CRD42022362868).

Respectful maternity care in the UK using a decolonial lens

Respectful maternity care (RMC) is part of a global movement addressing the previous absence of human rights in global safe maternal care guidance. RMC is grounded in kindness, compassion, dignity and respectful working conditions. The decolonisation movement in healthcare seeks to dismantle structural biases set up from a historically white, male, heteronormative Eurocentric medical system. This article applies a decolonising lens to the RMC agenda and examines barriers to its implementation in UK healthcare systems. Searches of peer-reviewed journals about decolonising maternity care in the UK revealed little. Drawing from wider information bases, we examine power imbalances constructed throughout a history of various colonial biases yet lingering in maternity care. The overarching findings of our analysis revealed 3 areas of focus: professional structures and institutional biases; power imbalances between types of staff and stakeholders of care; and person-centred care through a decolonial lens. To uproot inequity and create fairer and more respectful maternity care for women, birthing people and staff, it is vital that contemporary maternity institutions understand the decolonial perspective. This novel enquiry offers a scaffolding to undertake this process. Due to significant differences in colonial history between Western colonising powers, it is important to decolonise with respect to these different territories, histories and challenges.

Conceptualizing the Influence of Social and Structural Determinants of Neurobiology and Mental Health: Why and How Biological Psychiatry Can Do Better at Addressing the Consequences of Inequity

Psychiatry and allied disciplines have recognized the potency of structural and social determinants of mental health, yet there has been scant attention given to the roles of neurobiology in the links between structural and social determinants and mental health. In this article, we make the case for why greater attention must be given to structural and social determinants of biological psychiatry by researchers, practitioners, and policy-makers. After defining these terms and theoretical frameworks for considering their relevance in biological psychiatry, we review empirical research with marginalized and minoritized racial, ethnic, gender, sexual, and economic communities that reveals the ways in which structural and social determinants affect neurobiological functioning with implications for mental health. We give particular emphasis to developmental science and developmentally informed research, because structural and social determinants influence neurobiological adaptation and maturation across the lifespan. We conclude with recommendations for advancing research, practice, and policy that connect biological psychiatry with structural and social determinants of health. Foremost among these is diversifying the ranks of biological psychiatry, from classrooms through laboratories, hospitals, and community health centers. Transforming and advancing the understanding of the structural and social determinants of neurobiology and mental health is most likely to come through transforming the discipline itself.

What would it take to meaningfully attend to ethnicity and race in health research? Learning from a trial intervention development study

The lack of ethnic diversity in health research participation is a multi-dimensional problem. Racism and intersectional disadvantage compel us to use racial and ethnic categories to explore health, but race theorists warn that these can be essentialising and pathologising. Yet, the alternative, the pursuit of colour-blindness, can render the impact of race and ethnicity on health invisible. This paper describes the attempt to recruit an ethnically diverse sample to inform the development of an intervention for stroke patients. The study revealed deep uncertainties and tensions, which we use to re-examine our own positionalities and perspectives. We focus on the experiences of researchers and participants to show how 'usual' research practices are unwittingly exclusionary and promote 'methodological whiteness' (The British Journal of Sociology, 2017, 68, S214). Calls for greater diversity in research are frequently made, yet health research remains tainted by the use of problematic epistemological starting points, rendering participation by minoritised people uneasy. Medical sociologists, especially those engaged in clinical trials, have a vital role to play in recalibrating health research to attend to ethnicity and race. This requires us to reflect on our practices, to recognise where we are complicit in replicating social inequalities and to actively engage with communities to produce more inclusive research.
