Health Disparities in Recruitment and Enrollment in Research

From many voices, one question: Community co-design of a population-based qualitative cancer research study

PURPOSE

This study formed the development stage of a population-based survey aiming to: (i) understand the needs and experiences of people affected by cancer in Queensland, Australia and (ii) recruit a pool of participants for ongoing cancer survivorship research. The current study aimed to co-design and test a single qualitative survey question and study invitation materials to maximise acceptability of, and participation in, the survey and future research.

METHODS

Fifty-two community members, including cancer survivors and caregivers, participated across 15 co-design workshops and 20 pretest interviews. During workshops, participants generated and refined ideas for an open-ended survey question and provided feedback on a study invitation letter. The use of a single, open-ended question aims to minimise participant burden while collecting rich information about needs and experiences. The research team then shortlisted the question ideas and revised study invitation materials based on workshop feedback. Next, using interviews, community members were asked to respond to a shortlisted question to test its interpretability and relevance and to review revised invitation materials. Content analysis of participant feedback was used to identify principles for designing study materials.

RESULTS

Principles for designing qualitative survey questions were identified from participant feedback, including define the question timeframe and scope; provide reassurance that responses are valid and valued; and use simple wording. Principles for designing study invitation materials were also identified, including communicate empathy and sensitivity; facilitate reciprocal benefit; and include a 'human element'. The qualitative survey question and study invitation materials created using these principles were considered relevant and acceptable for use in a population-based survey.

CONCLUSIONS

Through community consultation and co-design, this study identified principles for designing qualitative data collection and invitation materials for use in cancer survivorship research. These principles can be applied by other researchers to develop study materials that are sensitive to the needs and preferences of community members.

Assessing disparities through missing race and ethnicity data: results from a juvenile arthritis registry

Introduction

Ensuring high-quality race and ethnicity data within the electronic health record (EHR) and across linked systems, such as patient registries, is necessary to achieving the goal of inclusion of racial and ethnic minorities in scientific research and detecting disparities associated with race and ethnicity. The project goal was to improve race and ethnicity data completion within the Pediatric Rheumatology Care Outcomes Improvement Network and assess impact of improved data completion on conclusions drawn from the registry.

Methods

This is a mixed-methods quality improvement study that consisted of five parts, as follows: (1) Identifying baseline missing race and ethnicity data, (2) Surveying current collection and entry, (3) Completing data through audit and feedback cycles, (4) Assessing the impact on outcome measures, and (5) Conducting participant interviews and thematic analysis.

Results

Across six participating centers, 29% of the patients were missing data on race and 31% were missing data on ethnicity. Of patients missing data, most patients were missing both race and ethnicity. Rates of missingness varied by data entry method (electronic vs. manual). Recovered data had a higher percentage of patients with Other race or Hispanic/Latino ethnicity compared with patients with non-missing race and ethnicity data at baseline. Black patients had a significantly higher odds ratio of having a clinical juvenile arthritis disease activity score (cJADAS10) of ≥5 at first follow-up compared with White patients. There was no significant change in odds ratio of cJADAS10 ≥5 for race and ethnicity after data completion. Patients missing race and ethnicity were more likely to be missing cJADAS values, which may affect the ability to detect changes in odds ratio of cJADAS ≥5 after completion.

Conclusions

About one-third of the patients in a pediatric rheumatology registry were missing race and ethnicity data. After three audit and feedback cycles, centers decreased missing data by 94%, primarily via data recovery from the EHR. In this sample, completion of missing data did not change the findings related to differential outcomes by race. Recovered data were not uniformly distributed compared with those with non-missing race and ethnicity data at baseline, suggesting that differences in outcomes after completing race and ethnicity data may be seen with larger sample sizes.

Social determinants of health and health disparities in glaucoma: A review

Social determinants of health and barriers to care can significantly impact patients' access to glaucoma care and treatment, resulting in disparities within disease presentation, progression, management, and treatment outcomes. The widespread adoption of electronic health record systems has allowed researchers and clinicians to further explore these relationships, identifying factors such as race, ethnicity, and socioeconomic status to be risk factors for more severe disease and lower treatment adherence. These disparities highlight potential targets for interventions to combat these disparities and improve overall patient outcomes. This article provides a summary of the available data on health disparities within glaucoma disease presentation, progression, management, treatment, and outcomes and discusses interventions to improve care delivery and outcomes among patients with glaucoma.

Pancreatic Cancer Multidisciplinary Clinic is Associated with Improved Treatment and Elimination of Socioeconomic Disparities

OBJECTIVE

To identify the association between multidisciplinary clinic (MDC) management and disparities in treatment for patients with pancreatic cancer.

BACKGROUND

Socioeconomic status (SES) predicts treatment and survival for pancreatic cancer. Multidisciplinary clinics (MDCs) may improve surgical management for these patients.

METHODS

This is a retrospective cohort study (2010-2018) of all pancreatic cancer patients within a large, regional hospital system with a high-volume pancreatic cancer MDC. The primary outcome was receipt of treatment (surgery, chemotherapy, radiation, clinical trial participation, and palliative care); the secondary outcomes were overall survival and MDC management. Multiple logistic regressions were used for binary outcomes. Survival was analyzed using Kaplan-Meier survival analysis, Cox proportional hazards, and inverse probability of treatment weighting (IPTW).

RESULTS

Of the 4141 patients studied, 1420 (34.3%) were managed by the MDC. MDC management was more likely for patients who were younger age, married, and privately insured, while less likely for low SES patients (all p < 0.05). MDC patients were more likely to receive all treatments, including neoadjuvant chemotherapy (OR 3.33, 95% CI 2.82-3.93), surgery (OR 1.39, 95% CI 1.15-1.68), palliative care (OR 1.21, 95% CI 1.05-1.38), and clinical trial participation (OR 3.76, 95% CI 2.86-4.93). Low SES patients were less likely to undergo surgery outside of the MDC (OR 0.47, 95% CI 0.31-0.73) but there was no difference within the MDC (OR 1.10, 95% CI 0.68-1.77). Across multiple survival analyses, low SES predicted inferior survival outside of the MDC, but there was no association among MDC patients.

CONCLUSION

Multidisciplinary team-based care increases rates of treatment and eliminates socioeconomic disparities for pancreatic cancer patients.

Effectiveness of multimodal participant recruitment in SPARK, a large, online longitudinal research study of autism

Background

SPARK launched in 2016 to build a US cohort of autistic individuals and their family members. Enrollment includes online consent to share data and optional consent to provide saliva for genomic analysis. SPARK's recruitment strategies include social media and support of a nation-wide network of clinical sites. This study evaluates SPARK's recruitment strategies to enroll a core study population.

Methods

Individuals who joined between January 31, 2018, and May 29, 2019 were included in the analysis. Data include sociodemographic characteristics, clinical site referral, the website URL used to join, how the participant heard about SPARK, enrollment completion (online registration, study consents, and returning saliva sample), and completion of the baseline questionnaire. Logistic regressions were performed to evaluate the odds of core participant status (completing enrollment and baseline questionnaire) by recruitment strategy.

Results

In total, 31,715 individuals joined during the study period, including 40% through a clinical site. Overall, 88% completed online registration, 46% returned saliva, and 38% were core participants. Those referred by a clinical site were almost twice as likely to be core participants. Those who directly visited the SPARK website or performed a Google search were more likely to be core participants than those who joined through social media.

Discussion

Being a core participant may be associated with the "personal" connection and support provided by a clinical site and/or site staff, as well as greater motivation to seek research opportunities. Findings from this study underscore the value of adopting a multimodal recruitment approach that combines social media and a physical presence.
