Importance of Sex and Gender Differences in Enrollment and Interpretation of Stroke Clinical Trials

OBJECTIVES

This review aims to reinforce the importance of improving sex balance in preclinical trials and sex and gender diversity and proportional balance in clinical trials enrollment and how this influences interpretation of stroke clinical trials. It also aims to identify strategies for improvement in data collection.

MATERIALS AND METHODS

A PubMed search was conducted of publications in English, using MeSH terms sex, sex characteristics, gender identity, transgender, gender-nonconforming persons, clinical trials as topic, stroke. Of 249 search results, 217 were human or animal studies related to stroke, the majority of which were reviews, secondary analyses of stroke clinical trials, meta analyses, or retrospective studies, subject to the methods of sex and gender acquisition per the primary data source. Articles were reviewed, noting inclusion or absence of sex and gender definitions and trial design. Selected articles were supplemented with United States Food and Drug Administration, National Institutes of Health, and National Academy of Science, Engineering, and Medicine publications.

RESULTS

The majority of preclinical studies continue to report sex as a binary variable, and the majority of stroke clinical trials report sex and gender as interchangeable and binary. Mindful trial design and statistical analysis can improve accuracy in the interpretation of sex and gender differences. Guidance exists to improve reporting on currently accepted sex and gender definitions, recommended data collection instruments, and appropriate statistical analyses.

CONCLUSIONS

Despite acknowledgement of having failed to achieve diverse and proportionally balanced enrollment, sex and gender imbalance across the research continuum remains prevalent. Responsible incorporation of sex and gender in stroke clinical trials can be achieved through thoughtful study design, use of contemporary sex and gender definitions, inclusive prospective data collection, balanced enrollment with prespecified goals, and appropriate statistical analysis.

Survey of NAACLS accredited histotechnology programs in the United States

Histotechnology educational programs are accredited by the National Accrediting Agency for Clinical Laboratory Sciences (NAACLS) and currently number fewer than 50 in the United States which contributes to the shortages of laboratory personnel. A survey tool designed with REDCap software was distributed to all programs identified on the NAACLS website and consisted of three parts: a) program information, b) facility information, and c) challenges. Programs are located primarily in large urban centers where populations are most concentrated. The median class size was 6 which may explain the excellent student outcomes to include 96% graduation rates and 90.7% board of registry examination pass rates. Overall, programs had ample equipment, funding, and administrative support. Costs to attend the programs were relatively low (<$3,000 per semester) for over half of the programs. However, due to the small number of accredited education programs across the US, potential students do not often have access to an institution in their area. The programs indicated that the most common challenge was recruitment of adequate high-quality candidates which may explain, in part, the persistent shortage of personnel in the histology laboratory.

Exploring Factors Influencing Family's Enrollment in Community-Based Health Insurance in the City of Gondar Peri-Urban Community, Northwest Ethiopia: A Health Belief Model Approach

Background

A research gap exists in finding practical solutions to provide affordable and accessible health insurance coverage to improve CBHI enrollment and sustainability to people in resource-poor settings and contribute to achieving universal health coverage (UHC) in Ethiopia. This research was initiated to analyze the role of community trust in scheme management and health choice to identify significant factors based on the health belief model (HBM). This psychological framework explains and predicts health behavior by considering individual perceptions.

Methods

Cross-sectional information was gathered from 358 families, and original facts were utilized. Descriptive data and the Binary logistics in the econometric model were applied for data analysis.

Findings

The descriptive findings demonstrated that other variables were established to possess a significant consequence except for job and occupation variables. The results of the logistic regression model showed that the distance of the nearest health station from the family's home in a minute [AOR (95% CI) =0.177 (0.015, -0.399)], being a member of the families having an official position in local government or cultural structure [AOR (95% CI) =0.574 (0.355, 0.793)], having an experience of visiting health facilities [AOR (95% CI) =0.281 (0.166, 0.396)], and perceiving the local CBHI scheme management as trustworthy [AOR (95% CI) =0.404 (0.233, 0.575)] were positively associated with family enrollment in the CBHI scheme. On the other hand, being a member of the "rotating saving and credit association" (ROSCA) [AOR (95% CI) =-.299 (-.478, -0.120)] was negatively associated with the family's enrollment in the CBHI scheme.

Conclusion

Trust in CBHI scheme management, family's experience of visiting health facilities, and distance from the nearest health station were essential factors influencing enrollment in CBHI schemes. "Rotating saving and credit association" (ROSCA) ° negatively and statistically significantly impacted the family's CBHI enrolment status. Income level was not associated with enrollment.

Going Viral: Assessing the Impact of Social Media on Enrollment in a Coronavirus Disease 2019 (COVID-19) Cohort Study

Objective This study aimed to quantify the effect of social media posts on study enrollment among children with mild coronavirus disease 2019 (COVID-19). Methods The primary outcome was weekly study enrollments analyzed using a run chart. A secondary analysis used linear regression to assess study enrollments two days before and after a social media post, adjusted for the statewide pediatric seven-day-average severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) case rate, social media posting day, and the interaction of these two variables. Results In seven months before social media posting, only eight patients were enrolled. One week after social media posting began, the median weekly enrollment increased (0 to 3). In the regression model, neither social media post day nor the pediatric SARS-CoV-2 case rate was significantly associated with enrollment rate. However, the interaction of a post day and the pediatric case rate was significant. Conclusion Social media posts significantly increased enrollment among children with mild COVID-19 in a prospective study. This effect was amplified by the presence of high community case rates during the Omicron wave.

Enrollment forecast for clinical trials at the portfolio planning phase based on site-level historical data

An accurate forecast of a clinical trial enrollment timeline at the planning phase is of great importance to both corporate strategic planning and trial operational excellence. The naive approach often calculates an average enrollment rate from historical data and generates an inaccurate prediction based on a linear trend with the average rate. Under the traditional framework of a Poisson-Gamma model, site activation delays are often modeled with either fixed initiation time or a simple random distribution while incorporating the user-provided site planning information to achieve good forecast accuracy. However, such user-provided information is not available at the early portfolio planning stage. We present a novel statistical approach based on generalized linear mixed-effects models and the use of non-homogeneous Poisson processes through the Bayesian framework to model the country initiation, site activation, and subject enrollment sequentially in a systematic fashion. We validate the performance of our proposed enrollment modeling framework based on a set of 25 preselected studies from four therapeutic areas. Our modeling framework shows a substantial improvement in prediction accuracy in comparison to the traditional statistical approach. Furthermore, we show that our modeling and simulation approach calibrates the data variability appropriately and gives correct coverage rates for prediction intervals of various nominal levels. Finally, we demonstrate the use of our approach to generate the predicted enrollment curves through time with confidence bands overlaid.

Who enrolls and why? Examining center-specific underlying patterns behind enrollment: a New York City-based traumatic brain injury model systems study

BACKGROUND

To elucidate the sociodemographic and study factors involved in enrollment in the Traumatic Brain Injury Model System (TBIMS) database, this study examined the effect of a variety of variables on enrollment at a local TBIMS center.

METHODS

A sample of 654 individuals from the local TBIMS center was studied examining enrollment by age, gender, race, ethnicity, homelessness status at date of injury, history of homelessness, health insurance status, presence of social support, primary language, consenting in hospital or after discharge, and the need for an interpreter. Binary logistic regression was conducted to identify variables that predict center-based enrollment into TBIMS.

RESULTS

Results demonstrated that older age was associated with decreasing enrollment (OR = 0.99, p = 0.01), needing an interpreter made enrollment less likely (OR = 0.33, p < 0.01), being primarily Spanish speaking predicted enrollment (OR = 3.20, p = 0.02), Hispanic ethnicity predicted enrollment (OR = 7.31, p = 0.03), and approaching individuals in the hospital predicted enrollment (OR = 6.94, p < 0.01). Here, OR denotes the odds ratio estimate from a logistic regression model and P denotes the corresponding p-value.

CONCLUSIONS

These results can be useful in driving enrollment strategies at this center for other similar TBI research, and to contribute a representative TBI sample to the national database.

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.

Including Socially Isolated Black, Older Old Adults (Aged 80 and Above) with and without Mild Cognitive Impairment in a Clinical Trial: Recruitment Strategies and Perspectives

Objective

This study describes strategies for the recruitment of socially isolated older old Black individuals to participate in the "Internet-based conversational engagement clinical trial (I-CONECT)" (Clinical Trial.gov: NCT02871921) and lessons learned in this critical population segment.

Methods

Best practice strategies to recruit the target population included mass mailings, advertisements, and direct community outreach, including the collaboration with a community group created to reach Black individuals interested in research participation. We also made protocol changes to measure recruitment criteria for older old Black adults more accurately and to increase their participation.

Results

Descriptive data related to the challenges and successes in recruiting Black participants compared to the White participants is presented. The primary site contacted 17,523 primarily White potential participants and enrolled/randomized 145 White and 2 Asian/mixed race participants (0.8%). The Midwest site contacted 12,141 Black potential participants and enrolled/randomized 39 (0.3%) participants.

Discussion

While best practices were employed, several factors complicated recruitment, including the need to adjust recruitment criteria, navigate regional regulations, and respect diverse community preferences.

Conclusion

Older old African Americans are reachable and willing to participate in research when considering their beliefs and practices, influenced by their community and experience.

Participation in genetic screening: testing different outreach methods across a diverse hospital system based patient population

Introduction: Genomics has the potential to transform medicine by identifying genetic risk factors that predispose people to certain illnesses. Use of genetic screening is rapidly expanding and shifting towards screening all patients regardless of known risk factors, but research is limited on the success of broad population-level outreach for genetic testing and the effectiveness of different outreach methods across diverse populations. In this study, we tested the effectiveness of Digital Only (emailing and texting) and Brochure Plus Digital (mailed brochure, emailing, and texting) outreach to encourage a diverse patient population to participate in a large hospital system's whole genome sequencing program. Methods: Disproportionate stratified sampling was used to create a study population more demographically diverse than the eligible population and response rates were analyzed overall and by demographics to understand the effectiveness of different outreach strategies. Results: 7.5% of all eligible patients enrolled in the program. While approximately 70% of patients invited to complete genetic testing identified in their EHR as being Hispanic, Black or African America, Asian, or another non-White race, these patients generally enrolled at lower rates than the overall population. Other underrepresented groups had higher enrollment rates including people with Medicaid coverage (8.7%) and those residing in rural areas (10.6%). We found no significant difference in enrollment rates between our Digital-Only and our Brochure Plus Digital outreach approaches in the overall population, but enrollment rates were significantly higher for Asian patients and patients who resided in rural areas in the Brochure Plus Digital group. Across both outreach approaches, links provided in emails were most commonly used for enrollment. Discussion: Our study reveals expected enrollment rates for proactive outreach by a hospital system for genetic testing in a diverse population. As more hospital systems are adopting population-scale genetic testing, these findings can inform future outreach efforts to recruit patients for genetic testing including those patients traditionally underrepresented in genomics.

Enhancing Enrollment in Acute Stroke Trials: Current State and Consensus Recommendations

The Stroke Treatment Academic Industry Roundtable (STAIR) convened a session and workshop regarding enrollment in acute stroke trials during the STAIR XII meeting on March 22, 2023. This forum brought together stroke physicians and researchers, members of the National Institute of Neurological Disorders and Stroke, industry representatives, and members of the US Food and Drug Administration to discuss the current status and opportunities for improving enrollment in acute stroke trials. The workshop identified the most relevant issues impacting enrollment in acute stroke trials and addressed potential action items for each. Focus areas included emergency consent in the United States and other countries; careful consideration of eligibility criteria to maximize enrollment and representativeness; investigator, study coordinator, and pharmacist availability outside of business hours; trial enthusiasm/equipoise; site start-up including contractual issues; site champions; incorporation of study procedures into standard workflow as much as possible; centralized enrollment at remote sites by study teams using telemedicine; global trials; and coenrollment in trials when feasible. In conclusion, enrollment of participants is the lifeblood of acute stroke trials and is the rate-limiting step for testing an exciting array of new approaches to improve patient outcomes. In particular, efforts should be undertaken to broaden the medical community's understanding and implementation of emergency consent procedures and to adopt designs and processes that are easily incorporated into standard workflow and that improve trials' efficiencies and execution. Research and actions to improve enrollment in ongoing and future trials will improve stroke outcomes more broadly than any single therapy under consideration.

Social and Emotional Skills Predict Postsecondary Enrollment and Retention

INTRODUCTION

Social and emotional (SE) skills are known to be linked to important life outcomes, many of which fall into the academic domain. For example, meta-analytic data show that the skill of Sustaining Effort is nearly or just as important for academic performance as intelligence. In a recent study with long-term tracking of high school students, those who came from schools with a strong emphasis on SE skill development were more likely to enroll in college within two years of high school graduation. Longitudinal studies like this one are rare, however.

METHOD

The focus of the present study is on the SE skills of 6662 students assessed during high school and their relationship with high school academic performance, standardized college admissions test performance, and ultimately postsecondary enrollment and retention.

RESULTS

We examined mean-level differences in household income, high school GPA, ACT Composite scores, and SE skills by college enrollment and retention status and found several significant differences, often favoring the enrolled or retained group. Moreover, we found support for the incremental validity of SE skills as they predicted enrollment and retention above household income, high school GPA, and ACT scores.

DISCUSSION

Understanding SE skills' effects on later academic outcomes is important to help inform early SE skill intervention and development efforts in secondary and postsecondary settings. Additional implications and future directions are discussed.

Recruitment and Retention Strategies Used in Dietary Randomized Controlled Interventions with Cancer Survivors: A Systematic Review

BACKGROUND

The purpose of this review was to systematically evaluate the quality of reporting of recruitment and retention methods in diet-related intervention trials among cancer survivors.

METHODS

A systematic search of five databases in Spring 2023 identified dietary intervention randomized controlled trials with a minimum of 50 cancer survivors, an intervention of at least eight weeks, and at least six months of study duration. Outcomes investigated include methodologic description and reporting of recruitment and retention rates.

RESULTS

Seventeen trials met inclusion criteria. Recruitment methods included cancer registry and clinician referral, hospital records, flyers, and media campaigns, and were reported in 88.2% of studies. Eleven of 17 studies (64.7%) met a priori recruitment goals. Eleven studies identified an a priori retention goal and seven met the goal. Retention goals were met more often for studies of less than one year (71.4%) versus greater than one year (50%), and for studies with remote or hybrid delivery (66.7%) versus only in-person delivery (50%).

CONCLUSIONS

Recruitment goals and methods are frequently reported; reporting of retention methods and goals is limited. Efforts are needed to improve reporting of retention methods and rates to inform best practices and enhance the rigor of future dietary intervention trials.

Cost of wound dressing: Implication for enrollment into the National Health Insurance scheme, Nigeria

BACKGROUND

 Enrollment into the National Health Insurance scheme (NHIS) still poses a challenge in Nigeria despite the established Group, Individual and Family Social Health Insurance Programme (GIFSHIP) during the coronavirus disease 2019 (COVID-19) pandemic.

OBJECTIVES

 This study examined the direct cost of wound dressing and enrollment into the health insurance scheme among hospitalised patients.

METHOD

 A descriptive cross-sectional research design was utilised to investigate the cost of wound dressing and enrollment into health insurance scheme among hospitalised patients in three selected hospitals of South-West Nigeria. The study was conducted from March 2021 to June 2021, and 190 patients were recruited via an interviewer-administered questionnaire. Ethical approvals were obtained from the hospitals while COVID-19 preventive protocols and ethical principles of autonomy, confidentiality and non-maleficence were observed.

RESULTS

 Majority of the respondents (91%) were not on any healthcare insurance scheme, only 4.2% were enrolled in NHIS while over 70% could not personally pay for their wound dressing. The minimum average cost of wound dressing materials per week and per acute care episode was ₦10 000.00 (Nigerian naira) and ₦50 000.00, respectively, while the minimum average cost for hospitalisation per week and per acute care episode was ₦18 000.00 and ₦130 000.00, respectively, ($1.00 equaled ₦600.00, June 2022).

CONCLUSION

 A lack of health insurance coverage is a precursor of 'out of pocket' payment. A political will is required to scale up enrollment of the indigenous population into the NHIS in Nigeria.Contribution: Many hospitalised patients are not enrolled in the NHIS and they are at a higher risk of catastrophic healthcare expenditure.

Choosing Veterans Affairs: Determinants of post-9/11 Veterans' enrollment in Veterans Affairs health care

Following recent policy changes, younger Veterans have particularly increased options for where to receive their health care. Although existing research provides some understanding of non-modifiable individual (e.g., age) and external community (e.g., non-VA provider supply) factors that influence VA enrollment, this study focused on modifiable facility access and quality factors that could influence Veterans' decisions to enroll in VA. In this cohort study, we examined enrollment in and use of VA services in the year following military separation as the binary outcome using mixed-effects logistic regressions, stratified by Active and Reserve Components. This study included 260,777 Active and 101,572 Reserve Component post-9/11 Veterans separated from the military in fiscal years 2016 to 2017. Independent variables included 4 access measures for timeliness of VA care and 3 VA quality measures, which are included in VA Medical Centers' performance plans. Eligible Veterans were more likely to enroll in VA when the closest VA had higher quality scores. After accounting for timeliness of VA care and non-modifiable characteristics, rating of primary care (PC) providers was associated with higher VA enrollment for Active Component (odds ratio [OR] = 1.014, 95% confidence interval [CI]: 1.007-1.020). Higher mental health (MH) continuity (OR = 1.039, 95% CI: 1.000-1.078) and rating of PC providers (OR = 1.009, 95% CI: 1.000-1.017) were associated with higher VA enrollment for Reserve Component. Improving facility-specific quality of care may be a way to increase VA enrollment. In a changing policy environment, study results will help VA leadership target changes they can make to manage enrollment of Veterans in VA and deliver needed foundational services.

The content and characteristics of face-to-face interventions to encourage patients' enrollment in cardiac rehabilitation; a scoping review

PURPOSE

To provide an overview of the content and characteristics of face-to-face interventions to encourage enrollment in exercise-based cardiac rehabilitation (CR).

METHODS

Following a published protocol describing the methods, six databases were searched. The search was limited to studies published from January 2000 to December 2021. Two reviewers independently performed study selection and data extraction.

RESULTS

5583 studies were identified and 20 studies with a variety of study designs met the inclusion criteria. Eight studies specified important content in face-to-face interventions to be: Education, problem-solving, support of autonomy, exploring reasons for change, emotional and cognitive support while showing understanding. Studies targeting patients' experiences used motivational interviewing and addressed worries and anticipated difficulties. Intention to attend, CR barriers, practical barriers, exercise self-efficacy, and patients asking questions supported enrollment. Reassurance could lead to nonattendance if patients had a high degree of worry and distress.

CONCLUSION

Face-to-face interventions are important to support patients' enrollment in CR and should integrate a person-centered dialogue exploring reasons for change and providing support to overcome barriers. Focus on the patients' perspectives, the mechanisms of change, and the evaluation of the intervention to inform implementation should be further explored.Implications for RehabilitationIn-hospital face-to-face interventions support enrollment in cardiac rehabilitation (CR) in patients with ischemic heart disease.This study suggests that individual worries and barriers toward CR should be jointly explored while considering patients' capacity for making choices as well as their vulnerability.Patients should be encouraged to ask questions.A too strong focus on reassurance and problem-solving can impede enrollment.

The impact of treatment preferences: A narrative review

Attending to treatment preferences is an element of person-centred care, reported as beneficial in improving treatment adherence, satisfaction, and outcome, in practice. The results of preference trials were inconsistent in supporting these benefits in intervention evaluation research. Informed by the conceptualisation of treatment preferences positing their indirect impact on outcomes, this narrative review aimed to summarise the evidence on the effects of preferences on enrolment; withdrawal or attrition; engagement, enactment, and satisfaction with treatment; and outcomes. The search yielded 72 studies (57 primary trials and 15 reviews). The results of vote counting indicated that (1) offering participants the opportunity to choose treatment enhances enrolment (reported in 87.5% of studies), and (2) providing treatments that match participants' preferences reduces attrition (48%); enhances engagement (67%), enactment (50%) and satisfaction with (43%) treatment; and improves outcomes (35%). The results are attributed to conceptual and methodological issues including less-than-optimal assessment of treatment preferences, which contributes to ill-identified preferences, accounting for withdrawal, low enactment, and limited satisfaction with treatment. These treatment processes, in turn, mediate the impact of treatment preferences on outcomes. It is important to refine and standardise the methods for assessing preferences and to examine their indirect impact (mediated by treatment processes) on outcomes in future preference trials to validly identify their benefits.

Strategies to Improve Enrollment and Participation in Pulmonary Rehabilitation Following a Hospitalization for COPD: RESULTS OF A NATIONAL SURVEY

PURPOSE

Pulmonary rehabilitation (PR) improves outcomes for patients with chronic obstructive pulmonary disease (COPD); however, very few patients attend. We sought to describe strategies used to promote participation in PR after a hospitalization for COPD.

METHODS

A random sample of 323 United States based PR programs was surveyed. Using a positive deviance approach, a 39-item survey was developed based on interviews with clinicians at hospitals demonstrating high rates of participation in PR. Items focused on strategies used to promote participation as well as relevant contextual factors.

RESULTS

Responses were received from 209 programs (65%), of which 88% (n = 184) were hospital-based outpatient facilities. Most (91%, n = 190) programs described enrolling patients continuously, and 80% (n = 167) reported a wait time from referral to the initial PR visit of <4 wk. Organization-level strategies to increase referral to PR included active surveillance (48%, n = 100) and COPD-focused staff (49%, n = 102). Provider-level strategies included clinician education (45%, n = 94), provider outreach (43%, n = 89), order sets (45%, n = 93), and automated referrals (23%, n = 48). Patient-level strategies included bedside education (53%, n = 111), flyers (49%, n = 103), motivational interviewing (33%, n = 69), financial counseling (64%, n = 134), and transportation assistance (35%, n = 73). Fewer than one-quarter (18%, n = 38) of PR programs reported using both bedside education and automatic referral, and 42% (n = 88) programs did not use either strategy.

CONCLUSIONS

This study describes current practices in the United States, and highlights opportunities for improvement at the organization, provider, and patient level. Future research needs to demonstrate the effectiveness of these strategies, alone or in combination.

Factors Associated With Enrollment into Inpatient Coronavirus Disease 2019 Randomized Controlled Trials: A Cross-sectional Analysis

Background

Clinical trials for coronavirus disease 2019 (COVID-19) have struggled to achieve diverse patient enrollment, despite underrepresented groups bearing the largest burden of the disease and, presumably, being most in need of the treatments under investigation.

Methods

To assess the willingness of patients to enroll into inpatient COVID-19 clinical trials when invited, we conducted a cross-sectional analysis of adults hospitalized with COVID-19 who were approached regarding enrollment. Associations between patient and temporal factors and enrollment were assessed by multivariable logistic regression analysis.

Results

A total of 926 patients were included in this analysis. Overall, Hispanic/Latinx ethnicity was associated with a nearly half-fold decrease in the likelihood to enroll (adjusted odds ratio [aOR], 0.60 [95% confidence interval {CI}, .41-.88]). Greater baseline disease severity (aOR, 1.09 [95% CI, 1.02-1.17]), age 40-64 years (aOR, 1.83 [95% CI, 1.03-3.25]), and age ≥65 years (aOR, 1.92 [95% CI, 1.08-3.42]) were each independently associated with higher likelihood to enroll. Over the course of the pandemic, patients were less likely to enroll during the summer 2021 wave in COVID-19-related hospitalizations (aOR, 0.14 [95% CI, .10-.19]) compared with patients from the first wave in winter 2020.

Conclusions

The decision to enroll into clinical trials is multifactorial. Amid a pandemic disproportionately affecting vulnerable groups, Hispanic/Latinx patients were less likely to participate when invited, whereas older adults were more likely. Future recruitment strategies must consider the nuanced perceptions and needs of diverse patient populations to ensure equitable trial participation that advances the quality of healthcare for all.

Considering Retention and Curricula in Reframing Pharmacy Enrollment Challenges

Enrollment in pharmacy education has been a topic of extensive discussions as the number of applications has declined. Some pharmacy programs have either not met enrollment goals or decreased incoming class sizes. This Commentary poses two questions that we must ask ourselves as an Academy. First, is it possible to realistically do more to recruit our way out of this situation in the next three to five years and beyond. Second, how, if possible, will pharmacy colleges and schools avoid the significant and transformative forces that could impact higher education in the future. Forces that are impacting higher education include changing demographics, transitioning from an industrial-based economy to a knowledge-based economy, and the continuing advances in technology with increased globalization as a component of all three of these forces. To address these questions, the concepts of student retention and success as well as considerations for reframing current curricular and pedagogical models and beliefs are challenged. In that pharmacy enrollment challenges are not likely to be easily resolved in the next few years, the Academy must place additional emphasis on issues related to student success and the design of our educational models and programs.

Recruitment of family caregivers of persons with dementia: Lessons learned from a pilot randomized controlled trial

Family caregivers play an essential role in supporting the health and well-being of older adults with dementia, a population projected to increase rapidly over the coming decades. Enrolling caregivers of people with dementia (PWD) in research studies is vital to generating the evidence necessary to support broader implementation of efficacious intervention programs in real-world care delivery, but a range of challenges impede recruitment and enrollment of sufficiently large and representative sample sizes. In this article, we characterize the challenges and lessons learned from recruiting caregivers of PWD to participate in a pilot randomized control trial. We utilize Bronfenbrenner's ecological model to categorize the challenges into three levels: individual (i.e., understanding caregivers' time constraints and motivations), community (i.e., reaching underrepresented populations and accessing caregiver support groups) and institutional (i.e., obtaining informed consent and navigating research registries). We found that establishing rapport and maintaining flexibility with participants was crucial for motivating individuals to enroll in our study. Building trust with local communities by collaborating with support group leaders, appointing a co-investigator who is already embedded within a given community, and establishing equitable partnerships with organizations increased recruitment rates. At the institutional level, engaging experts in regulatory affairs and geriatrics may help overcome barriers in obtaining approval from institutional review boards. We also recommend using research registries of individuals who offer their contact information to researchers. The lessons learned from our research-including the challenges and potential solutions to overcome them-may promote more effective and efficient recruitment in future research.

Enrollment and retention of female sex workers in HIV care in health facilities in Mbarara city

Background

Sex work is a global driver of the HIV epidemic, and the risk of acquiring HIV is 13 times higher for female sex workers (FSWs) compared to the general population. The enrollment and retention of FSWs in HIV care is a challenge and has been a major contributing factor to increased new HIV infections.

Methods

We conducted a qualitative study among 30 FSWs and 21 healthcare workers (HCWs) working in antiretroviral therapy (ART) clinics at the selected three primary health facilities in Mbarara City, Southwestern Uganda. The study participants were enrolled by both purposive and snowball sampling techniques. We obtained informed consent from all the participants, and data were collected using in-depth interviews and thematically analyzed.

Results

Three themes emerged as facilitators toward enrollment and retention of FSWs into HIV care, namely, (1) good health living, (2) receptive HCWs and availability of health services, and (3) community outreach services and peer support. The barriers are summarized into four major themes: (1) stigma, community discrimination, and beliefs; (2) social obstacles; (3) adverse effects of ART; and (4) inadequate services at the health facilities.

Conclusion

FSWs are challenged by unsupportive environments and communities where they live and work, which hinders their enrollment and retention in HIV care. Creating awareness of the utilization of HIV care services and extending such services to hotspot communities could enhance the response of HIV-positive FSWs to ART.

Barriers to Screening: An Analysis of Factors Impacting Screening for Type 1 Diabetes Prevention Trials

Context

Participants with stage 1 or 2 type 1 diabetes (T1D) qualify for prevention trials, but factors involved in screening for such trials are largely unknown.

Objective

To identify factors associated with screening for T1D prevention trials.

Methods

This study included TrialNet Pathway to Prevention participants who were eligible for a prevention trial: oral insulin (TN-07, TN-20), teplizumab (TN-10), abatacept (TN-18), and oral hydroxychloroquine (TN-22). Univariate and multivariate logistic regression models were used to examine participant, site, and study factors at the time of prevention trial accrual.

Results

Screening rates for trials were: 50% for TN-07 (584 screened/1172 eligible), 9% for TN-10 (106/1249), 24% for TN-18 (313/1285), 17% for TN-20 (113/667), and 28% for TN-22 (371/1336). Younger age and male sex were associated with higher screening rates for prevention trials overall and for oral therapies. Participants with an offspring with T1D showed lower rates of screening for all trials and oral drug trials compared with participants with other first-degree relatives as probands. Site factors, including larger monitoring volume and US site vs international site, were associated with higher prevention trial screening rates.

Conclusions

Clear differences exist between participants who screen for prevention trials and those who do not screen and between the research sites involved in prevention trial screening. Participant age, sex, and relationship to proband are significantly associated with prevention trial screening in addition to key site factors. Identifying these factors can facilitate strategic recruitment planning to support rapid and successful enrollment into prevention trials.

Enrollment of reproductive age women in community-based health insurance: An evidence from 2019 Mini Ethiopian Demographic and Health Survey

Background

Universal health coverage (UHC) is aimed at ensuring that everyone has access to high-quality healthcare without the risk of financial ruin. Community-based health insurance (CBHI) is one of the essential means to achieve the sustainable development goals (SDGs) global health priority of UHC. Thus, this study assessed health insurance enrollment and associated factors among reproductive age women in Ethiopia.

Methods

We computed the health insurance enrollment of reproductive-age women using secondary data from the recent Ethiopian Mini Demographic and Health Surveys (EMDHS) 2019. The EMDHS was a community-based cross-sectional study carried out in Ethiopia from March 21 to June 28, 2019. Cluster sampling with two stages was employed for the survey. The study comprised 8885 (weighted) reproductive-age women. STATA 14 was used for data processing and analysis. Bivariate and multivariable logistic regression analyses were conducted. Adjusted odds ratio (AOR) with 95% confidence interval (CI) was reported and statistical significance was set at a value of p < 0.05.

Results

Of the 8,885 study participants, 3,835 (43.2, 95% CI; 42.1, 44.2%) of women had health insurance. Women aged 20-24 years, 25-29 years, and 30-34 years less likely to enroll in health insurance compared to their younger counterparts (15-19 years). Women living in rural areas, had greater than five family sizes, living with a female household head, and having more than five living children were negatively associated with enrollment in health insurance. Besides, health insurance enrollment among reproductive-age women is significantly affected by region and religious variation.

Conclusion

The overall CBHI enrolment among reproductive-age women in Ethiopia was low. To achieve the SDGs of reducing maternal mortality ratio and neonatal mortality, improving reproductive-age women's access to health insurance is essential. The national, regional, and local officals, policymakers, NGOs, program planners, and other supporting organizations working on improving health insurance enrollment of reproductive age women need to create awareness and support them based on these significant factors.

Comparison of the Speed of Enrollment for Clinical Trials Conducted by Japanese and Global Pharmaceutical Companies

Since the establishment of the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH), many countries in the world have rapidly improved their clinical trial performance, and the era has come to compare the clinical trial performance of each country. Japan's clinical trials are considered excellent quality, but costly and slow. In this study, we examined the speed of enrollment period in clinical trials. We surveyed clinical trials from January 1, 2010, to December 31, 2019, covering the top 10 pharmaceutical companies in each global sales ranking (Global 10) and the Japanese sales ranking (Japan 10). Clinical trial data were obtained from ClinicalTrials.gov, a clinical trial registration information database, and the speed of participant enrollment (cases/month) was compared for each phase of the trials. The number of clinical trials conducted during the 10 years was 8938 trials for Global 10 and 1439 trials for Japan 10. Comparing the speed of participant enrollment by phase, Japan 10 was significantly faster in phase 1 for both healthy subjects and oncology patients. [Japan 10: Global 10; 15.1 : 12.0 cases/month (healthy subjects) and 5.5 : 1.8 cases/month (oncology), respectively. p < 0.001]. Global 10 was also significantly faster in phase 3. [Japan 10: Global 10; 12.4: 36.9 cases/month, p < 0.001). No significant difference was observed in phase 2 and phase 4. There was a possibility that the speed of enrollment differed by phase between global companies and Japanese domestic companies.

Screening and enrollment of underrepresented ethnocultural and educational populations in the Alzheimer's Disease Neuroimaging Initiative (ADNI)

INTRODUCTION

An analysis of the ethnocultural and socioeconomic composition of Alzheimer's Disease Neuroimaging Initiative (ADNI) participants is needed to assess the generalizability of ADNI data to diverse populations.

METHODS

ADNI data collected between October 2004 and November 2020 were used to determine ethnocultural and educational composition of the sample and differences in the following metrics: screening, screen fails, enrollment, biomarkers.

RESULTS

Of 3739 screened individuals, 11% identified as being from ethnoculturally underrepresented populations (e.g., Black, Latinx) and 16% had <12 years of education. Of 2286 enrolled participants, 11% identified as ethnoculturally underrepresented individuals and 15% had <12 years of education. This participation is considerably lower than US Census data for adults 60+ (ethnoculturally underrepresented populations: 25%; <12 years of education: 4%). Individuals with <12 years of education failed screening at a higher rate.

DISCUSSION

Our findings suggest that ADNI results may not be entirely generalizable to ethnoculturally diverse and low education populations.

Clinical Trial Enrollment Among Adolescent and Young Adults with Primary Central Nervous System Tumors Treated at the Dana-Farber Cancer Institute

Purpose: In recent decades, the survival outcomes among adolescent and young adults (AYAs, 15-39 years) have not improved substantially, especially among AYAs with primary central nervous system (CNS) tumors. While this is likely multifactorial, low participation in clinical trials among AYAs is thought to be a critical contributing factor. In this study, we describe the pattern of clinical trial enrollment among AYAs with primary CNS tumors at our institution. Methods: We performed a retrospective, IRB-approved chart review of AYAs with CNS tumors treated at the Dana-Farber Cancer Institute (DFCI) between January 2009 and December 2018. We used logistic regression analyses and descriptive statistics to analyze this sample and determine the clinical trial enrollment at the pediatric affiliate (Dana-Farber/Boston Children's Cancer and Blood Disorders Center) and adult affiliate (Dana-Farber/Brigham and Women's Cancer Center). Results: Ninety-three AYA patients with primary CNS tumors were treated at the Dana-Farber/Boston Children's Cancer and Blood Disorders Center, while 507 patients with primary CNS gliomas were treated at the Dana-Farber/Brigham and Women's Cancer Center. At the pediatric affiliate, 35.4% (33/93) of AYAs were enrolled in a therapeutic clinical trial, while at the adult affiliate, 15.8% (80/507) of AYAs were enrolled in a clinical trial. High-grade gliomas were associated with significantly higher rates of enrollment in the adult affiliate. Conclusions: Clinical trial enrollment remains poor among AYAs with CNS tumors, and clinical trial enrollment participation is modestly higher in the pediatric setting. Our study demonstrates the continued need to evaluate and address factors associated with clinical trial enrollment among AYAs with CNS tumors.

Digital culturally tailored marketing for enrolling Latino participants in a web-based registry: Baseline metrics from the Brain Health Registry

INTRODUCTION

This culturally tailored enrollment effort aims to determine the feasibility of enrolling 5000 older Latino adults from California into the Brain Health Registries (BHR) over 2.25 years.

METHODS

This paper describes (1) the development and deployment of culturally tailored BHR websites and digital ads, in collaboration with a Latino community science partnership board and a marketing company; (2) an interim feasibility analysis of the enrollment efforts and numbers, and participant characteristics (primary aim); as well as (3) an exploration of module completion and a preliminary efficacy evaluation of the culturally tailored digital efforts compared to BHR's standard non-culturally tailored efforts (secondary aim).

RESULTS

In 12.5 months, 3603 older Latino adults were enrolled (71% of the total California Latino BHR initiative enrollment goal). Completion of all BHR modules was low (6%).

DISCUSSION

Targeted ad placement, culturally tailored enrollment messaging, and culturally tailored BHR websites increased enrollment of Latino participants in BHR, but did not translate to increased module completion.

HIGHLIGHTS

Culturally tailored social marketing and website improvements were implemented. The efforts enrolled 5662 Latino individuals in 12.5 months. The number of Latino Brain Health Registry (BHR) participants increased by 122.7%. We failed to adequately enroll female Latinos and Latinos with lower education. Future work will evaluate effects of a newly released Spanish-language BHR website.

Inclusion of patients with chronic kidney disease in randomized phase 3 clinical trials in patients with prostate, breast, lung, and colorectal cancer

The objective of this study was to determine the proportion of phase 3 clinical trials investigating a systemic therapy for patients with prostate, breast, lung, or colorectal cancer that excluded patients with Chronic Kidney Disease (CKD) and the exclusion criteria chosen, if any. A search was conducted using the ClinicalTrials.gov database to identify eligible studies. Of the 268 included trials, 185 (69%) had at least one renal exclusion criteria. Of these 185 trials, 116 (63%) had an undefined exclusion criterion. Only disease site was associated with exclusion of patients with CKD in the univariate analysis, but no factors in the multivariate analysis. There are several potential barriers to including patients with CKD in clinical trials. Nevertheless, solutions can be proposed to allow the inclusion of these patients. This would allow them to access to innovative therapeutic strategies, but also allow a better applicability of trial results to this patient population.

INFORMATION GAPS AND HEALTH INSURANCE ENROLLMENT: Evidence from the Affordable Care Act Navigator Programs

We studied the impact of Affordable Care Act navigator programs on health insurance coverage, using the 80 percent cut in program funding under the Trump administration as a natural experiment. Our study design exploited county-level differences in the program prior to funding cuts. We did not find that cuts to the program significantly decreased rates of marketplace coverage or any health insurance coverage by 2019; however, our estimates could not rule out marketplace coverage declines of up to 2.7 percent (point estimate -1.3 percent, 95 percent CI: 2.7 percent to 0.1 percent), or total coverage declines of up to 1.8 percentage points (point estimate -0.8 percentage points or -1.2 percent, 95 percent CI: -1.8 to 0.2). Cuts to the navigator program significantly decreased marketplace coverage and total coverage among lower-income adults, and significantly decreased total coverage among adults under age 45, Hispanic adults, and adults who speak a language other than English at home. We found no significant impact of the cuts on Medicaid enrollment (95 percent CI: -1.9 percentage points to 0.5 percentage points); most uninsured people in the states we studied lived in locations that had not implemented Medicaid eligibility expansions. These findings suggest that before the funding cuts, navigators were helping underserved consumers obtain coverage.

Increasing Latinx representation in the US medical schools: A top-ranked medical school's experience

Despite the increasing racial and ethnic diversity of the general US population, many, if not most, medical schools fall short of matriculating students reflective of this change in diversity. The Latinx community constitutes nearly 20% of the US population and is expected to rise substantially in the coming decades. Over the past 20 years, the number of Latinx students applying to and being admitted to medical school has grown but remains below 4% of the total medical student body composition. Several factors contribute to the under-representation of Latinx students in medical schools that include access to secondary education, finances, lack of mentorship or advice, and a multitude of other structural inequities and system-level biases. Diversity, equity, and inclusion are often named as key pillars of workforce development across the US medical schools and academic institutions. Despite significant efforts, medical schools continue to have low Latinx representation within their student body, and recruitment efforts often lack sustainability. In this manuscript, we share our experience of increasing Latinx student representation within a top-ranked medical school in the US southeast region. We have discussed the barriers we faced in enrolling and attracting Latinx students' amidst similar under-representation of Latinx faculty, staff, and leadership and the challenges of financial support for applicants and financial aid packages for admitted students. The strategies we implemented to achieve an increased representation of Latinx students in the School of Medicine (SOM) included revitalizing the Latino Medical Student Association (LMSA), ensuring Latinx student representation within the SOM admission committee that included Latinx faculty as active participants in recruitment and retention efforts, redesigning the medical Spanish course, and creating dedicated outreach plans during second look weekend for interested Latinx students and active outreach to applicants and accepted students by current students. In combination, these efforts led to a significant increase in Latinx representation in the SOM student body from 2.6% in 2009 to 12.2% in 2021. We will conclude by discussing our ongoing challenges and our approach to sustain and improve Latinx representation in our medical school.

Medicaid Disruption Among Transition-Age Youth on the Autism Spectrum

Enrollment in Medicaid facilitates access to needed services among transition-age youth on the autism spectrum and youth with intellectual disability (ID). There are long-standing programs to ensure that individuals with ID remain enrolled as they age; similar programs for autistic youth are newer, not as widespread, and may not be as effective. We compared Medicaid disenrollment and re-enrollment between transition-age youth on the autism spectrum, youth with ID, and youth with both diagnoses using a national claims-based prospective cohort study from 2008 through 2012. Autistic youth were most likely to disenroll and least likely to re-enroll. Disenrollment peaked for all three groups at ages 19 and 21. Transition-age youth on the autism spectrum experience more disruptions in access to Medicaid-reimbursed services than youth with ID. More equitable Medicaid enrollment options for autistic individuals are needed to ensure their access to critical health care as they age.

Screening for participants in the ISCHEMIA trial: Implications for clinical research

The International Study of Comparative Health Effectiveness with Medical and Invasive Approaches (ISCHEMIA) found that there was no statistical difference in cardiovascular events with an initial invasive strategy as compared with an initial conservative strategy of guideline-directed medical therapy for patients with moderate to severe ischemia on noninvasive testing. In this study, we describe the reasons that potentially eligible patients who were screened for participation in the ISCHEMIA trial did not advance to enrollment, the step prior to randomization. Of those who preliminarily met clinical inclusion criteria on screening logs submitted during the enrollment period, over half did not participate due to physician or patient refusal, a potentially modifiable barrier. This analysis highlights the importance of physician equipoise when advising patients about participation in randomized controlled trials.

Recruitment and Retention Strategies for the Diabetes RElated to Acute Pancreatitis and Its Mechanisms Study: From the Type 1 Diabetes in Acute Pancreatitis Consortium

ABSTRACT

Recruitment and retention of patients with acute pancreatitis (AP) in clinical studies can be challenging. While some obstacles are similar to other clinical conditions, some are unique to AP. Identifying potential barriers early and developing targeted solutions can help optimize recruitment and retention in AP studies. Such pre-emptive and detailed planning can help prospective, longitudinal studies focus on exocrine and endocrine complications of AP in accurately measuring outcomes. This article highlights the challenges in recruitment and retention strategies in AP studies and reviews available resources to create opportunities to address them. We describe the multifaceted approach used by the Recruitment and Retention Committee of the Type 1 Diabetes in Acute Pancreatitis Consortium, which builds upon earlier experiences to develop a recruitment and retention plan for the DREAM (Diabetes RElated to Acute pancreatitis and its Mechanisms) study.

Potential Impact of Revised NCI Eligibility Criteria Guidance: Prior Malignancy Exclusion in Breast Cancer Clinical Trials

BACKGROUND

Many individuals with cancer have survived a prior cancer and for this reason may have been excluded from clinical trials. Recent NCI guidance recommends including these individuals, especially when the risk of the prior malignancy interfering with either safety or efficacy endpoints is very low. Using breast cancer as an example, we determined the potential effect this policy change may have on clinical trial accrual.

PATIENTS AND METHODS

We reviewed protocols of NCI-sponsored breast cancer clinical trials activated in 1991 through 2016. We quantified prevalence of prior cancer-related exclusion criteria and assessed the association with trial characteristics using Fisher's exact tests. Using SEER data, we estimated the prevalence and timing of prior primary (nonbreast) cancer diagnoses among patients with breast cancer.

RESULTS

Among 87 clinical trials (total target enrollment, 137,253 patients), 77% excluded individuals with prior cancer, most commonly (79%) within the preceding 5 years. Among trials with radiographic response or toxicity endpoints, 69% excluded prior cancer. In SEER data, the prevalence of a prior (nonbreast) cancer diagnosis ranged from 5.7% to 7.7%, depending on breast cancer stage, of which 39% occurred within 5 years of the incident breast cancer. For trials excluding prior cancer, the estimated proportion of patients excluded for this reason ranged from 1.3% to 5.8%, with the estimated number of excluded patients ranging from 1 to 288.

CONCLUSIONS

More than three-fourths of NCI-sponsored breast cancer clinical trials exclude patients with prior cancer, including almost 70% of trials with response or toxicity endpoints. Given that >5% of patients with breast cancer have a history of prior cancer, in large phase III trials this practice may exclude hundreds of patients. Following recent NCI eligibility guidance, the inclusion of patients with prior cancer on breast cancer trials may have a meaningful impact on accrual.

The Need for Improved Recruitment to Neurosurgery Training: A Systematic Review of Enrollment Strategies

Neurosurgery is one of the cornerstones corresponding to a large scope of clinical pathologies and is a highly-regarded surgical specialty. However, there has been a decline in recruits into the neurosurgical residency due to many factors derailing the interest of medical students with an ambition to become neurosurgeons. Some of these issues encompass little or lack of early exposure to neurosurgery, lack of quality mentorship programs, and institutional curriculum entailing prolonged periods of training and study in neurosurgery. Therefore, this systematic review and meta-analysis aim to establish some strategic methodologies for increasing the recruitment to neurological surgery. Neurosurgery is an interestingly exciting specialty that integrates cutting-edge technology allowing for diversified subspecialization with an exceptional degree of variety. Nevertheless, several factors such as the duration of the required training, the kind of lifestyle, lack of early exposure to neurosurgery, and lack of mentors to a vast of medical students across the globe have curtailed the recruitment to neurological surgery. Despite an increased number of female representations in medical surgery, there has been a reported increase in students matching into neurosurgery, although the number is relatively below the expectation due to the factors highlighted earlier. As a result, many studies and surveys have been conducted to identify ways of improving neurosurgical recruitment.

Five electronic databases, including PubMed, Science Direct, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Google Scholar, MEDLINE, and Cochrane Library, were searched to provide pertinent information to the topic of study in strict compliance with the PRISMA (Preferred Reporting Items for Systematic Review and Meta-analysis) guidelines. Meta-analysis was then conducted on the included studies to determine their correlations based on the individual outcomes of each study. A total of 2,134 search results were obtained, screened, and reviewed against the exclusion and inclusion criteria to remain with 12 included studies detailing improving the recruitment to neurosurgical residency. The 12 studies were retrieved for their study characteristics based on the PICO (predetermined patient, intervention, control, and outcome) standards. Most of the studies were surveys (n = 8), retrospective and prospective studies (n = 2), and pilot and multifocal studies making up for the rest (n = 2). Several neurosurgery aspects need consideration to improve the recruitment of medical students to neurosurgical fields. Medical institutions, specialists, and other stakeholders should consider reconstructing the neurosurgical curriculum to ease the prolonged study time as well as to create and encourage structural programs aimed at acquainting medical students in neurosurgery and involving the students in conducting other research projects. In addition, mentorship programs and early exposure of medical students to neurological surgery play a key role in influencing the medical students' interest in choosing neurosurgical career paths.

Real time monitoring and prediction of time to endpoint maturation in clinical trials

In clinical trials, almost all key milestone dates can be defined in terms of time to endpoint maturation (TTEM). The real time monitoring and accurate prediction of TTEM have a significant impact on clinical trial planning and execution and can bring significant value to clinical trial practitioners. TTEM is defined as the time to achieve or observe a certain number or percentage of some endpoint of interest. It is a combination of time to site initiation, time to subject enrollment after site initiation and time to event of interest after subject enrollment. To better predict TTEM during the trial, the future site initiation and subject enrollment have to be taken into account while predicting the number of events. In this article, we propose a novel simulation-based framework combining time to site initiation, time to subject enrollment and time to event in order to predict TTEM. A nonhomogeneous Poisson process with a quadratic time-varying rate function is used to model site initiation and subject enrollment and more advanced time to event models had been explored and integrated on top of them, such as Weibull, piecewise exponential, and model averaging which is equivalent to a Bayesian model selection strategy. To evaluate the predictive performance of the proposed methodology, we conducted extensive simulations and applied the methodology to 14 randomly selected real oncology phase 2 and phase 3 studies in both solid tumor and hematology with a total 31 study-endpoint combinations. The predictive performance of the proposed methodology was then compared with popular and commonly available commercial software, for example, East (Cytel, Cambridge, MA, USA). From both simulation and real data, the proposed methodology can significantly improve the prediction accuracy by up to 54% compared to the commonly available method.

An integrated approach to improve clinical trial efficiency: Linking a clinical trial management system into the Research Integrated Network of Systems

Low-accruing clinical trials delay translation of research breakthroughs into the clinic, expose participants to risk without providing meaningful clinical insight, increase the cost of therapies, and waste limited resources. By tracking patient accrual, Clinical and Translational Science Awards hubs can identify at-risk studies and provide them the support needed to reach recruitment goals and maintain financial solvency. However, tracking accrual has proved challenging because relevant patient- and protocol-level data often reside in siloed systems. To address this fragmentation, in September 2020 the South Carolina Clinical and Translational Research Institute, with an academic home at the Medical University of South Carolina, implemented a clinical trial management system (CTMS), with its access to patient-level data, and incorporated it into its Research Integrated Network of Systems (RINS), which links study-level data across disparate systems relevant to clinical research. Within the first year of CTMS implementation, 324 protocols were funneled through CTMS/RINS, with more than 2600 participants enrolled. Integrated data from CTMS/RINS have enabled near-real-time assessment of patient accrual and accelerated reimbursement from industry sponsors. For institutions with bioinformatics or programming capacity, the CTMS/RINS integration provides a powerful model for tracking and improving clinical trial efficiency, compliance, and cost-effectiveness.

A Qualitative Analysis of Factors Influencing Critical Care Trial Enrollment Among Surrogates

BACKGROUND

We sought to identify factors that influence surrogate decision makers' decisions to enroll patients into a critical care randomized controlled trial.

METHODS

We conducted a qualitative study embedded within a randomized controlled trial testing the effect of a behavioral nudge intervention for surrogate decision makers on enrollment rate in a sham ventilatory weaning trial among patients with acute respiratory failure. Participants were adult surrogate decision makers of patients receiving mechanical ventilation for acute respiratory failure. The study was conducted in 10 ICUs across 2 urban hospitals within an academic medical center in Philadelphia, Pennsylvanaia, United States. Immediately following their trial enrollment decision, surrogate decision makers were asked to enter free-text responses about the factors that influenced their decision. Responses were analyzed using content analysis.

RESULTS

Of the 90 (49%) participants who provided free-text responses, the mean age was 54.9 years (SD 14.3), 69 (79%) were Caucasian, and 48 (53%) were the spouse of the eligible patient. We identified 5 themes influencing enrollment decisions: (i) trial characteristics, (ii) patient clinical condition, (iii) decision making processes, (iv) altruism, and (v) enrollment attempt. Among surrogates who enrolled the patient in the trial (n = 40), the most commonly cited factors were helping future patients (n = 24, 60%) and following the patient's wishes (n = 11, 28%). In contrast, those who declined enrollment (n = 50) most commonly reported that the patient was too sick (n = 27, 54%) and that they feared complicating the patient's condition (n = 11, 22%).

CONCLUSIONS

Surrogates who enroll patients into trials most often cite altruistic motivations, while those who decline enrollment are most often concerned with the severity of the patients' condition.

Barriers to Pediatric Oncologist Enrollment of Adolescents and Young Adults on a Cross-Network National Clinical Trials Network Supportive Care Cancer Clinical Trial

Few studies have explored interventions to improve adolescent and young adult (AYA) cancer care delivery. While many AYAs receive cancer care at NCI Community Oncology Research Program (NCORP) sites, few enroll on clinical trials. Barriers and facilitators to pediatric oncologist activation of and enrollment on an AYA cross-network National Clinical Trials Network (NCTN) supportive care trial were assessed using a survey that was administered to 162 stakeholders representing all 47 children's oncology group (COG) institutions affiliated to an NCORP. Fifty-eight stakeholders participated representing 62% of all sites surveyed. Approximately half of participants (45%) were unaware of the trial. Seven sites had the study open and one enrolled a patient. Reasons for not opening and enrolling on the trial included limited research staff and resources, low anticipated accrual, and lower prioritization of the trial. Enrollment facilitators included having a local "AYA champion," improving communication between pediatric and medical oncology, and having site education on available AYA trials. Interventions focused on increasing site and provider awareness of AYA trials and decreasing local barriers to AYA enrollment are needed.

Adolescent and young adult enrollment to a National Cancer Institute-sponsored National Clinical Trials Network Research Group over 25 years

BACKGROUND

Adolescent and young adult (AYA) patients with cancer have not seen the same improvements in survival as younger (pediatric) patients and older patients (adults 40 years old or older). This may be related to their lower participation in clinical trials.

METHODS

This study examined AYA patient accrual to SWOG Cancer Research Network phase 1 to 3 clinical treatment trials for 29 cancers over 25 years (January 1996 to December 2020). Trial enrollments for AYA patients (15-39 years old) were compared with trial enrollments for older patients (40 years old or older) in SWOG and with US AYA cancer population rates derived from US Census and National Cancer Institute/Surveillance, Epidemiology, and End Results data.

RESULTS

In total, 84,219 patients were enrolled in SWOG treatment trials, including 7109 AYA patients (8.4%); in contrast, AYAs constituted 3.8% of the US cancer population. By histology, the highest proportions of AYA patients were in trials for Hodgkin disease (825 of 1220; 67.6%) and acute lymphocytic leukemia (350 of 678; 51.6%), whereas breast cancer trials had the greatest number of AYA patients (3032 of 32,693; 9.3%). SWOG AYA patients were more often female (68.8% vs 58.7%; P < .001), Black (10.1% vs 8.2%; P < .001), and Hispanic (10.6% vs 5.6%; P < .001) than SWOG patients who were 40 years old or older, and they were more often female (68.8% vs 65.1%; P < .001) but less often Black (10.1% vs 11.8%; P < .001) or Hispanic (10.6% vs 12.8%; P < .001) than AYA patients in the US cancer population.

CONCLUSIONS

AYA patients with cancer were well represented in SWOG clinical trials in comparison with US cancer population patients with the same cancers. The SWOG AYA population was more racially/ethnically diverse than older SWOG patients, although it was less diverse than the US AYA cancer population.

LAY SUMMARY

Adolescent and young adult (AYA) patients with cancer (aged 15-39 years) have not seen the same improvements in survival as younger (pediatric) patients and older patients (adults 40 years old or older). This may be related to their lower participation in clinical trials. This study evaluated the extent to which AYA patients were enrolled in a large, National Cancer Institute-sponsored network group over 25 years (1996-2020). Overall, 8.4% of the enrolled patients (7109 of 84,219) were AYAs; this was twice the corresponding rate of 3.8% in the US cancer population. AYA patients were also more racially/ethnically diverse than older trial patients, although they were less racially/ethnically diverse than the US AYA cancer population.

Clinical Trial Participation: A Pilot Study of Patient-Identified Barriers

BACKGROUND

Clinical trial enrollment in the United States is lacking, particularly among older adult and ethnic and racial minority populations.

OBJECTIVES

The aim of the current study was to identify patient-related barriers to clinical trial participation using a mixed-methods patient survey and to offer insights to develop evidence-based implementation strategies to address these barriers.

METHODS

A retrospective survey was conducted of patients who were not interested in participating in a clinical trial to quantify the reasons these patients chose not to participate. Directed qualitative content analysis was used to identify themes that emerged from the write-in responses.

FINDINGS

The greatest patient-reported barriers were misperceptions about placebos, a desire to not feel like a human guinea pig, uncertainty surrounding clinical trial treatment effectiveness compared to standard care, and concerns about additional appointments or tests. Oncology nurses can address patient enrollment barriers by providing targeted education and participating in the informed consent process.

General Practice and Digital Methods to Recruit Stroke Survivors to a Clinical Mobility Study: Comparative Analysis

BACKGROUND

Participant recruitment remains a barrier to conducting clinical research. The disabling nature of a stroke, which often includes functional and cognitive impairments, and the acute stage of illness at which patients are appropriate for many trials make recruiting patients particularly complex and challenging. In addition, people aged 65 years and older, which includes most stroke survivors, have been identified as a group that is difficult to reach and is commonly underrepresented in health research, particularly clinical trials. Digital media may provide effective tools to support enrollment efforts of stroke survivors in clinical trials.

OBJECTIVE

The objective of this study was to compare the effectiveness of general practice (traditional) and digital (online) methods of recruiting stroke survivors to a clinical mobility study.

METHODS

Recruitment for a clinical mobility study began in July 2018. Eligible study participants included individuals 18 years and older who had a single stroke and were currently ambulatory in the community. General recruiting practice included calling individuals listed in a stroke registry, contacting local physical therapists, and placing study flyers throughout a university campus. Between May 21, 2019, and June 26, 2019, the study was also promoted digitally using the social network Facebook and the search engine marketing tool Google AdWords. The recruitment advertisements (ads) included a link to the study page to which users who clicked were referred. Primary outcomes of interest for both general practice and digital methods included recruitment speed (enrollment rate) and sample characteristics. The data were analyzed using the Lilliefors test, the Welch two-sample t test, and the Mann-Whitney test. Significance was set at P=.05. All statistical analyses were performed in MATLAB 2019b.

RESULTS

Our results indicate that digital recruitment methods can address recruitment challenges regarding stroke survivors. Digital recruitment methods allowed us to enroll study participants at a faster rate (1.8 participants/week) compared to using general practice methods (0.57 participants/week). Our findings also demonstrate that digital and general recruitment practices can achieve an equivalent level of sample representativeness. The characteristics of the enrolled stroke survivors did not differ significantly by age (P=.95) or clinical scores (P=.22; P=.82). Comparing the cost-effectiveness of Facebook and Google, we found that the use of Facebook resulted in a lower cost per click and cost per enrollee per ad.

CONCLUSIONS

Digital recruitment can be used to expedite participant recruitment of stroke survivors compared to more traditional recruitment practices, while also achieving equivalent sample representativeness. Both general practice and digital recruitment methods will be important to the successful recruitment of stroke survivors. Future studies could focus on testing the effectiveness of additional general practice and digital media approaches and include robust cost-effectiveness analyses. Examining the effectiveness of different messaging and visual approaches tailored to culturally diverse and underrepresented target subgroups could provide further data to move toward evidence-based recruitment strategies.

Strategies for Sustainability of University-Based Medical Laboratory Sciences Programs

The COVID-19 pandemic has taken a major toll on the economy and funding for public education. For that reason, the pandemic has a worrisome effect on the sustainability of university/college based Medical Laboratory Sciences MLS training programs. Stakeholders of university-based MLS programs include university administrators, students, clinical affiliates and faculty. Each group has specific goals and challenges that affect the sustainability of the program. This report details strategies that can be used to satisfy the goals specific to key stakeholders that lead to sustainability. These strategies apply in pandemic times and in the back-to-normal future.

Methods for Authenticating Participants in Fully Web-Based Mobile App Trials from the iReach Project: Cross-sectional Study

Background

Mobile health apps are important interventions that increase the scale and reach of prevention services, including HIV testing and prevention counseling, pre-exposure prophylaxis, condom distribution, and education, of which all are required to decrease HIV incidence rates. The use of these web-based apps as well as fully web-based intervention trials can be challenged by the need to remove fraudulent or duplicate entries and authenticate unique trial participants before randomization to protect the integrity of the sample and trial results. It is critical to ensure that the data collected through this modality are valid and reliable.

Objective

The aim of this study is to discuss the electronic and manual authentication strategies for the iReach randomized controlled trial that were used to monitor and prevent fraudulent enrollment.

Methods

iReach is a randomized controlled trial that focused on same-sex attracted, cisgender males (people assigned male at birth who identify as men) aged 13-18 years in the United States and on enrolling people of color and those in rural communities. The data were evaluated by identifying possible duplications in enrollment, identifying potentially fraudulent or ineligible participants through inconsistencies in the data collected at screening and survey data, and reviewing baseline completion times to avoid enrolling bots and those who did not complete the baseline questionnaire. Electronic systems flagged questionable enrollment. Additional manual reviews included the verification of age, IP addresses, email addresses, social media accounts, and completion times for surveys.

Results

The electronic and manual strategies, including the integration of social media profiles, resulted in the identification and prevention of 624 cases of potential fraudulent, duplicative, or ineligible enrollment. A total of 79% (493/624) of the potentially fraudulent or ineligible cases were identified through electronic strategies, thereby reducing the burden of manual authentication for most cases. A case study with a scenario, resolution, and authentication strategy response was included.

Conclusions

As web-based trials are becoming more common, methods for handling suspicious enrollments that compromise data quality have become increasingly important for inclusion in protocols.

medical school admissions and enrollment practices: status of LGBTQ inclusivity

CONTEXT

The failure to collect information on lesbian, gay, bisexual, transgender, and queer (LGBTQ) identity in healthcare and medical education is a part of a systemic problem that limits academic medical institutions' ability to address LGBTQ health disparities.

OBJECTIVES

To determine whether accurate sexual and gender minority (SGM) demographic data is being consistently collected for all US medical schools during admissions and enrollment, and whether differences exist between collection practices at osteopathic and allopathic schools.

METHODS

Secure, confidential electronic were sent via email in July 2019 to 180 osteopathic (n=42) and allopathic (n=138) medical schools identified through the American Association of Colleges of Osteopathic Medicine Student Guide to Osteopathic Medical Colleges database and the American Association of Medical Colleges Medical School Admissions Requirements database. The nine question survey remained open through October 2019 and queried for; (1) the ability of students to self report SGM status during admissions and enrollment; and (2) availability of SGM specific resources and support services for students. Chi square analysis and the test for equality of proportions were performed.

RESULTS

Seventy five of 180 (41.7%) programs responded to the survey; 74 provided at least partial data. Of the 75 respondent schools, 55 (73.3%) allowed applicants to self report a gender identity other than male or female, with 49 (87.5%) of those being allopathic schools compared with 6 (31.6%) osteopathic schools. Similarly, 15 (20.0%) allowed applicants to report sexual orientation, with 14 (25.5%) of those being allopathic schools compared with one (5.3%) osteopathic school. Fifty four of 74 (73.0%) programs allowed matriculants to self report a gender identity other than male or female; 11 of 74 (14.7%) allowed matriculants to report sexual orientation.

CONCLUSIONS

Demographics collection practices among American medical education programs that responded to our survey indicated that they undervalued sexual orientation and gender identity, with osteopathic programs being less likely than allopathic programs to report inclusive best practices in several areas. American medical education programs, and their supervising bodies, must update their practices with respect to the collection of sexual orientation and gender identity demographics as part of a holistic effort to address SGM health disparities.

Tailoring Research Recruitment for Acute Care Settings: Recommendations from People with Dementia and their Caregivers

BACKGROUND

There is a pressing need to increase enrollment and representation in Alzheimer's disease and related dementia (ADRD) research. Current recruitment approaches focus largely on clinic and community settings, with minimal engagement of acute care environments despite their broad use across diverse populations. The objectives of this study were to examine views, preferences, and recommendations regarding acute care-based ADRD research recruitment among persons with dementia and their caregivers.

METHODS

The authors conducted semistructured interviews with recently hospitalized persons with dementia (N=3) and family caregivers (N=28). Interviews were analyzed using thematic analysis.

FINDINGS

All participants endorsed acute care as an appropriate time for recruitment into ADRD research studies and identified important elements of an appropriately tailored recruitment approach and an interpersonally effective research staff. Participants emphasized that this approach should consider the acute care context with respect to participant situation, uncertainty, and timing. Participant suggestions informed the design of a 5-step process to guide ADRD research recruitment in the context of acute care.

DISCUSSION

Findings provide valuable insights from people with dementia and their caregivers regarding opportunities for research engagement surrounding acute care and can inform expanded recruitment in these settings.

Reasons for Exclusion of Apparently Healthy Mature Adult and Senior Dogs From a Clinical Trial

Background: Interventional clinical trials intended to maintain health in aging dogs are unusual and require particular attention to exclusion criteria.

Objectives: To describe reasons for exclusion when a mature adult and senior canine population with normal health status was sought.

Animals: Fifty six companion dogs nominated for a randomized controlled trial (RCT).

Procedures: Exclusions occurred within Stage 1 (S1): owner-provided survey information; Stage 2 (S2): medical records review; and Stage 3 (S3): screening examination and within Owner, Dog, or Other factor categories.

Results: Of 56 nominated dogs, 39 were excluded at S1 (n = 19), S2 (n = 5), and S3 (n = 15), respectively. Dogs were excluded for Owner (n = 4), Dog (n = 27), Other (n = 6), and concurrent (Owner + Dog; n = 2) factors. The most common exclusion period was S1 (n = 19), with weight outside the target range being the most common exclusion factor in that stage (n = 10). Heart murmurs were the second most common exclusion factor (S1: n = 1; S3: n = 5); suspected or confirmed systemic illness was third most common (S1: n = 2; S2: n = 3; S3: n = 2). Among dogs who passed S1 and S2 screening (n = 32), 15 dogs (48%) were excluded at S3, for heart murmur > grade II/VI (n = 5), cardiac arrhythmias (n = 2), and clinicopathologic abnormalities (n = 2).

Conclusions and Clinical Relevance: Dogs nominated for a clinical trial for healthy mature adult and senior dogs were excluded for size, previous diagnoses, and newly discovered cardiac abnormalities. For future interventions in mature adult and senior dogs of normal health status, it is important to define expected age-related abnormalities to ensure that meaningful exclusion criteria are used.

Patient Recruitment Into a Multicenter Clinical Cohort Linking Electronic Health Records From 5 Health Systems: Cross-sectional Analysis

Background

There is growing interest in identifying and recruiting research participants from health systems using electronic health records (EHRs). However, few studies have described the practical aspects of the recruitment process or compared electronic recruitment methods to in-person recruitment, particularly across health systems.

Objective

The objective of this study was to describe the steps and efficiency of the recruitment process and participant characteristics by recruitment strategy.

Methods

EHR-based eligibility criteria included being an adult patient engaged in outpatient primary or bariatric surgery care at one of 5 health systems in the PaTH Clinical Research Network and having ≥2 weight measurements and 1 height measurement recorded in their EHR within the last 5 years. Recruitment strategies varied by site and included one or more of the following methods: (1) in-person recruitment by study staff from clinical sites, (2) US postal mail recruitment letters, (3) secure email, and (4) direct EHR recruitment through secure patient web portals. We used descriptive statistics to evaluate participant characteristics and proportion of patients recruited (ie, efficiency) by modality.

Results

The total number of eligible patients from the 5 health systems was 5,051,187. Of these, 40,048 (0.8%) were invited to enter an EHR-based cohort study and 1085 were enrolled. Recruitment efficiency was highest for in-person recruitment (33.5%), followed by electronic messaging (2.9%), including email (2.9%) and EHR patient portal messages (2.9%). Overall, 779 (65.7%) patients were enrolled through electronic messaging, which also showed greater rates of recruitment of Black patients compared with the other strategies.

Conclusions

We recruited a total of 1085 patients from primary care and bariatric surgery settings using 4 recruitment strategies. The recruitment efficiency was 2.9% for email and EHR patient portals, with the majority of participants recruited electronically. This study can inform the design of future research studies using EHR-based recruitment.

"Why would you not listen? It is like being given the winning lottery numbers and deciding not to take them": semi-structured interviews with post-acute myocardial infarction patients and their significant others exploring factors that influence participation in cardiac rehabilitation and long-term exercise training

PURPOSE

Despite the clinical benefits, coronary artery disease patient participation rates in cardiac rehabilitation (CR) and long-term exercise are poor. This study explored the factors related to participation in these interventions from the perspectives of post-acute myocardial infarction (AMI) patients and their significant others.

METHODS

Semi-structured interviews were performed with post-AMI patients (number (n) = 10) and their significant others (n = 10) following phase-III and phase-IV CR. Reflexive thematic analysis with an inductive orientation was utilised to identify themes within the dataset (ClinicalTrials.gov identifier: NCT03907293).

RESULTS

The overarching theme of the data was a perceived need to improve health, with the participants viewing health benefits as the principal motive for participating in CR and long-term exercise training. Three further themes were identified: motivation, extrinsic influences, and CR experience. These themes captured the underlying elements of the participants' decision to take part in CR and long-term exercise training for the purpose of health improvements.

CONCLUSION

An AMI collectively impacts the attitudes and beliefs of patients and their significant others in relation to CR participation, long-term exercise, and health. The factors identified in this study may inform strategies to promote patient enrollment in CR and adherence to long-term exercise.IMPLICATIONS FOR REHABILITATIONPost-AMI patients and their significant others reported that health benefits were the primary motive for participating in CR and long-term exercise, with aspects related to motivation, extrinsic influences, and CR experience underpinning the decision.Healthcare professionals should supply information about health benefits during the CR referral process, with insights into the experiences of CR graduates potentially improving the strength of recommendation.CR facilitators may promote long-term exercise adherence by assisting patients with the identification of an enjoyable exercise modality.Healthcare professionals should include significant others in the CR referral process, which may enable these individuals to support the patients' decisions.
