Investigation of Ethnic Differences in Willingness to Enroll in a Rehabilitation Research Registry

The risk of re-identification versus the need to identify individuals in rare disease research

There is a growing concern in the ethics literature and among policy makers that de-identification or coding of personal data and biospecimens is not sufficient for protecting research subjects from privacy invasions and possible breaches of confidentiality due to the possibility of unauthorized re-identification. At the same time, there is a need in medical science to be able to identify individual patients. In particular for rare disease research there is a special and well-documented need for research collaboration so that data and biosamples from multiple independent studies can be shared across borders. In this article, we identify the needs and arguments related to de-identification and re-identification of patients and research subjects and suggest how the different needs may be balanced within a framework of using unique encrypted identifiers.

Promoting Retention: African American Older Adults in a Research Volunteer Registry

Objectives: The objectives of this study were to evaluate the capability of a research volunteer registry to retain community-dwelling African American older adults, and to explore demographic and health factors associated with retention. Method: A logistic regression model was used to determine the influence of demographics, health factors, and registry logic model activities on retention in a sample of 1,730 older African American adults. Results: Almost 80% of participants active in the volunteer research registry between January 2012 and June 2015 were retained. Employment, being referred to research studies, a higher number of medical conditions, and more follow-up contacts were associated with an increased likelihood of retention. Older age, more months in the registry, and more mobility problems decreased the likelihood of retention. Discussion: These results suggest the Michigan Center for Urban African American Aging Research logic model promotes retention through involving older African American adults in research through study referrals and intensive follow-up. The loss of participants due to age- and mobility-related issues indicate the registry may be losing its most vulnerable participants.

Cultural aspects related to informed consent in health research: A systematic review

BACKGROUND

In order to protect the autonomy of human subjects, we need to take their culture into account when we are obtaining informed consent.

OBJECTIVE AND RESEARCH DESIGN

This study describes the cultural aspects related to informed consent in health research and is based on electronic searches that were conducted using the Scopus, PubMed, CINAHL, and Cochrane databases published between 2000 and 2013. A total of 25 articles were selected.

FINDINGS

Our findings indicate that cultural perspectives relating to the informed consent process are essential during the whole research process and particularly crucial in the planning phase of a study. Our study indicates that appropriate communication between different stakeholders plays a vital role in cultural understanding.

DISCUSSION AND CONCLUSION

The researchers' awareness of cultural differences and their ability to work in a culturally sensitive way are key factors in improving study participation and retention in a multicultural context. Taking cultural aspects into account during the whole research process improves the quality of research.

Perspectives on neurological patient registries: a literature review and focus group study

Background

Patient registries represent a well-established methodology for prospective data collection with a wide array of applications for clinical research and health care administration. An examination and synthesis of registry stakeholder perspectives has not been previously reported in the literature.

Methods

To inform the development of future neurological registries we examined stakeholder perspectives about such registries through a literature review followed by 3 focus groups comprised of a total of 15 neurological patients and 12 caregivers.

Results

(1) Literature review: We identified 6,435 abstracts after duplicates were removed. Of these, 410 articles underwent full text review with 24 deemed relevant to perspectives about neurological and non-neurological registries and were included in the final synthesis. From a patient perspective the literature supports altruism, responsible use of data and advancement of research, among others, as motivating factors for participating in a patient registry. Barriers to participation included concerns about privacy and participant burden (i.e. extra clinic visits and associated costs). (2) Focus groups: The focus groups identified factors that would encourage participation such as: having a clear purpose; low participant burden; and being well-managed among others.

Conclusions

We report the first examination and synthesis of stakeholder perspectives on registries broadly with a specific focus on neurological patient registries. The findings of the broad literature review were congruent with the neurological patient and caregiver focus groups. We report common themes across the literature and the focus groups performed. Stakeholder perspectives need to be considered when designing and operating patient registries. Emphasizing factors that promote participation and mitigating barriers may enhance patient recruitment.

Joint replacement recipients' views about health information privacy

BACKGROUND

Researchers are concerned about the possibility of restricted access to data as a result of specific consent requirements in privacy legislation, potentially resulting in smaller samples and a lack of representativeness which could bias results. In addition, there is uncertainty about what influences individuals to give consent for the use of their personal health information.

OBJECTIVE

To measure joint replacement recipients' health information privacy views and to assess potential predictors of these views.

DESIGN

Cross-sectional survey.

SETTING AND PARTICIPANTS

Potential joint replacement recipients from two teaching hospitals in London, Ontario, Canada.

MAIN VARIABLES

Age, gender, education, employment status, anticipated joint replacement, and expectations for surgery.

MAIN OUTCOME MEASURES

Privacy concerns as measured by the Concern Scale.

RESULTS

The response rate was 182/253 or 72%. The mean Concern score was 143.9/235.0 for the total sample (range = 82-216). Women had higher levels of privacy concerns than men on slightly over half of the individual questionnaire items. In women, surgical joint, age and employment explained 15% of the variance in concerns about personal health information privacy (P = 0.001). The model explained 6% of the variance in concerns in men (P = 0.138) and was not statistically significant.

DISCUSSION AND CONCLUSION

This study indicates that demographic characteristics and health-care experiences play a role in the variability of health information privacy concerns. A greater understanding of patients' privacy views about health information could lead to a greater harmonization among privacy rules, research and data access, and the preferences of health-care consumers.

Attempts to reach the oldest and frailest: recruitment, adherence, and retention of urban elderly persons to a falls reduction exercise program

PURPOSE OF THE STUDY

To assess the recruitment, adherence, and retention of urban elderly, predominantly African Americans to a falls reduction exercise program.

DESIGN AND METHODS

The randomized controlled trial was designed as an intervention development pilot study. The goal was to develop a culturally sensitive intervention for elderly persons who suffered a fall and visited an emergency department (ED). Participants were taught exercises during 4 on-site group classes and encouraged to continue exercising at home for 12 weeks and attend additional on-site monthly classes. The protocol included a specifically designed intervention for increasing retention through trained community interventionists drawn from the participants' neighborhoods.

RESULTS

The screening of 1,521 ED records after falling yielded the recruitment of 204 patients aged 65 years and older. Half were randomized into the falls prevention program. Of the 102 people in the intervention group, 92 completed the final 6-month assessment, 68 attended all on-site sessions, but only 1 reported exercising at home all 12 weeks. Those who lived alone were more likely (p = .03) and those with symptoms of depression were less likely (p = .05) to attend all on-site exercise classes. The final recruitment rate was estimated as 31.8%. The final retention rates were 90.2% and 87.3% for the intervention and control groups, respectively.

IMPLICATIONS

Recruitment of frail elderly African American patients is resource intensive. Adherence to the on-site exercise classes was better than to the home-based component of the program. These findings have implications for the design of future community-based exercise programs and trials.

An automated communication system in a contact registry for persons with rare diseases: scalable tools for identifying and recruiting clinical research participants

OBJECTIVES

Strategies for study recruitment are useful in clinical research network settings. We describe a registry of individuals who have self-identified with one of a multiplicity of rare diseases, and who express a willingness to be contacted regarding possible enrollment in clinical research studies. We evaluate this registry and supporting tools in terms of registry enrollment and impact on participation rates in advertised clinical research studies.

METHODS

A web-based automated system generates periodic and customized communications to notify registrants of relevant studies in the NIH Rare Diseases Clinical Research Network (RDCRN). The majority of these communications are sent by email. We compare the characteristics of those enrolled in the registry to the characteristics of participants enrolled in sampled RDCRN studies in order to estimate the impact of the registry on study participation in the network.

RESULTS

The registry currently contains over 4000 registrants, representing 40 rare diseases. Estimates of study participation range from 6-27% for all enrollees. Study participation rates for some disease areas are over 40% when considering only contact registry enrollees who live within 100 mi of a clinical research study site.

CONCLUSIONS

Automated notifications can facilitate consistent, customized, and timely communication of relevant protocol information to potential research subjects. Our registry and supporting communication tools demonstrate a significant positive impact on study participation rates in our network. The use of the internet and automated notifications make the system scalable to support many protocols and registrants.

Joint replacement recipients' post-surgery views about health information privacy and registry participation

Patient registries have been demonstrated to improve health care, and represent an important source of data to health researchers and policy-makers. Building on our previous research that tested an explanatory model of health information privacy views with pre-operative joint replacement recipients, in the present study we explored privacy views and willingness to participate in registries among post-operative joint replacement recipients. Post-operative patients were asked to complete a self-administered mailed questionnaire. One hundred and fifty-seven of 173 (91%) eligible individuals were enrolled. Bivariate analyses were conducted using t-tests and one-way ANOVAs. Multivariable analyses were conducted using multiple linear regression. Overall, our previous findings that views about health information privacy are more predictive of potential registry participation than patient characteristics or health care experiences continue to hold true post-surgery. Certain health care experiences were found to play a role in health information privacy concerns, including hip versus knee replacement, primary versus revision surgery, and surgical complications. More variance was explained in post-surgery registry participation views than pre-surgery. In addition, gender differences in R(2) values were smaller post-surgery. However, some aspects of the final models, such as gender as an effect modifier continued in the post-surgery study. Researchers and policy-makers should consider the impact of encounters with the health care system when seeking to understand patients' privacy concerns and willingness to participate in registries.

The Health Insurance Portability and Accountability Act of 1996 (HIPAA) privacy rule: implications for clinical research

In the short time since it became effective for health care organizations, a privacy regulation issued under the Health Insurance Portability and Accountability Act of 1996 (HIPAA) has had a significant adverse impact on the conduct of clinical research in the United States, without a substantial corresponding increase in privacy protection for research participants. Some of the problems associated with HIPAA have been resolved through revisions since the regulation's initial promulgation in December 2000, and other problems can be addressed by better educating health care providers and researchers about its requirements and available alternatives for compliance; however, considerable structural challenges remain. These constitute substantial barriers to research and resulting medical advances. Additional revisions to HIPAA based on the principles and trade-offs reflected in the Common Rule-which responsibly balances an individual's interest in privacy protection with the public interest in gaining knowledge through biomedical research-can go a long way to remedying remaining flaws in the system.

A patient registry for cognitive rehabilitation research: a strategy for balancing patients' privacy rights with researchers' need for access

OBJECTIVE

To describe a consent-based Patient Research Registry designed to improve the quality and efficiency of cognitive rehabilitation research by balancing patients' privacy rights with researchers' need for access to research participants.

DESIGN

Description of a protocol for a Patient Research Registry.

SETTING

Three rehabilitation hospitals.

PARTICIPANTS

Inpatients with stroke or traumatic brain injury (TBI) at the 3 participating hospitals.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Percentages of eligible patients with stroke or TBI who consented to be enrolled in the Registry, were subsequently contacted about a study, and ultimately participated in a study. A survey examined satisfaction with the Registry among researchers who used it for recruitment.

RESULTS

After 36 months of operation, 58% of patients approached have consented to be in the Registry (N=1256). Eighty-seven percent of those later identified as potential subjects for research studies expressed interest, and 63% eventually participated. Researchers reported satisfaction with the recruitment opportunities afforded by the Registry.

CONCLUSIONS

The Registry succeeded in identifying eligible patients interested in participating in research studies, while safeguarding their privacy rights. We identify its strengths and limitations and characterize the type of facility that would most profit from adopting this recruitment model.
