Recruitment and retention: nursing research among low-income pregnant women

Factors associated with study protocol adherence and bio banking participation in reproductive medicine clinical trials and their relationship to live birth

STUDY QUESTION

What demographic and baseline characteristics are predictive of adherence to reproductive medicine clinical trial protocols, live birth or participation in genetic studies?

SUMMARY ANSWER

Race, BMI and lower income are associated with likelihood of non-adherent to reproductive medicine clinical trial protocols, while race influences collection of biological samples and non-adherent to study protocols is associated with lower probability of live birth.

WHAT IS KNOWN ALREADY

Although aspects of adherence to study protocol have previously been evaluated as individual factors in infertile women, the factors that affect overall non-adherent to study protocol have not been previously evaluated.

STUDY DESIGN, SIZE, DURATION

A secondary data analysis of 1650 participants from two prospective multicenter, double-blind controlled studies was carried out: Pregnancy in Polycystic Ovary Syndrome II (PPCOS II) and Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS).

PARTICIPANTS/MATERIALS, SETTING, METHODS

The participants were women aged 18-40 years old with either polycystic ovary syndrome (PCOS) with ovulatory dysfunction in combination with either hyperandrogenemia and/or polycystic ovarian morphology (PPCOS II), or regular ovulatory cycles with unexplained infertility (AMIGOS). The study was carried out in 14 clinical sites in the USA. Non-adherence to clinical trial protocol was chosen as the primary outcome for this analysis. To evaluate whether demographic and baseline characteristics were predictive of adherence to study protocols, live birth or participation in blood sampling for DNA and repository, and pregnancy registry, these putative factors were compared between the outcome measures. Logistic regression was used to establish a prediction model using the putative predictors introduced above.

MAIN RESULTS AND THE ROLE OF CHANCE

Women who self-identified as African American or Asian and those with higher BMI and lower household income were less likely to adhere to protocol. Non-adherence to the study protocol was associated with a lower probability of live birth (odds ratio: 0.180, 95% CI: 0.120, 0.272, P < 0.001). African Americans or Asians were less likely to participate in optional study DNA collection compared to Whites. Participants who were African American or with high annual income or from the Southwest sites or had PCOS were less likely to participate in the blood repository studies.

LIMITATIONS, REASONS FOR CAUTION

Race and ethnicity were self-reported and such self-classification to strict race and ethnicity may not always be representative of a whole racial or ethnic group. This study included two US multicenter trials and therefore the findings may not be extrapolated to international trials.

WIDER IMPLICATIONS OF THE FINDINGS

Identification of populations with low participation is an important initial step, as further investigation can develop specific measures to improve adherence to study protocols and participation in biospecimen banking and thereby extend the representativeness of reproductive medicine clinical trial findings.

Nursing informatics: two foundational developments

Health informatics technologies exist to support the work of the health professionals. As successful healthcare outcomes increasingly rest on the active participation of patients and lay persons, these technologies must also directly support the important contributions of patients as they engage in self-help, self-care, and disease management activities. The unique role of nursing in the healthcare system is to attend to those aspects of the person that constitute the human response to disease and development, and to deliver interventions that help to compensate for, restore, or improve patients’ abilities to manage health status. This uniqueness is reflected in the terms used by nurses to characterize patient problems, which are operationally distinct from those used in medicine, and also in the nature of homecare technologies needed by nurses. Nurses provide an important but distinct contribution to patient care, and the informatics technologies needed to support nurses and their patients are complementary but distinctly different from those that support the medical aspect of care. Two developments in health informatics, formal languages and telehealth, serve as the core foundations of technological support for healthcare in the twenty-first century. Nurses contribute to and benefit from advances in language development and telehealth innovations.

Recruiting underserved mothers to medical research: findings from North Carolina

Representative samples are required for ethical, valid, and useful health research. Yet, recruiting participants, especially from historically underserved communities, can be challenging. This paper presents findings from in-depth interviews with 40 mothers about factors that might influence their willingness to participate or allow their children to participate in medical research. Saliency analysis organizes the findings. Frequent and important salient themes about research participation included concerns that it might cause participants harm, hope that participants might gain a health benefit, and recognition that time and transportation resources could limit participation. Ultimately, we propose that a theoretical model, such as the Theory of Planned Behavior (TPB), will facilitate more systematic evaluation of effective methods for recruitment and retention of participants in medical research. Future research should explore the utility of such a model for development of effective recruitment and retention strategies.

Is a randomised controlled trial of a maternity care intervention for pregnant adolescents possible? An Australian feasibility study

Background

The way in which maternity care is provided affects perinatal outcomes for pregnant adolescents; including the likelihood of preterm birth. The study purpose was to assess the feasibility of recruiting pregnant adolescents into a randomised controlled trial, in order to inform the design of an adequately powered trial which could test the effect of caseload midwifery on preterm birth for pregnant adolescents.

Methods

We recruited pregnant adolescents into a feasibility study of a prospective, un-blinded, two-arm, randomised controlled trial of caseload midwifery compared to standard care. We recorded and analysed recruitment data in order to provide estimates to be used in the design of a larger study.

Results

The proportion of women aged 15–17 years who were eligible for the study was 34% (n=10), however the proportion who agreed to be randomised was only 11% (n = 1). Barriers to recruitment were restrictive eligibility criteria, unwillingness of hospital staff to assist with recruitment, and unwillingness of pregnant adolescents to have their choice of maternity carer removed through randomisation.

Conclusions

A randomised controlled trial of caseload midwifery care for pregnant adolescents would not be feasible in this setting without modifications to the research protocol. The recruitment plan should maximise opportunities for participation by increasing the upper age limit and enabling women to be recruited at a later gestation. Strategies to engage the support of hospital-employed staff are essential and would require substantial, and ongoing, work. A Zelen method of post-randomisation consent, monetary incentives and ‘peer recruiters’ could also be considered.

Recruiting underserved populations to dermatologic research: a systematic review

Recruitment of participants to dermatologic research studies can be challenging, particularly with historically underserved populations. Recruitment of these groups is essential to ethical, valid, and useful dermatologic research. This article discusses findings from a review of 78 studies that examined factors influencing participation in health research studies with an emphasis on underserved populations, particularly women and ethnic minorities. The most commonly encountered barriers to research participation are mistrust of research, lack of access to research programs, and culturally incompetent research design. Motives to participate in research include receipt of benefit from participation, perceived opportunities to help others, and culturally competent research design. Practical methods for addressing barriers and enhancing research participation include culturally competent research design, community-based recruitment, and easily understandable informed consent. These factors should be considered when recruiting subjects for dermatologic research, especially when recruitment of underserved populations is desired. In addition, the literature demonstrates a paucity of research among rural residents, infants, and children, as well as within clinical dermatologic research.

An exploration of lifetime trauma exposure in pregnant low-income African American women

OBJECTIVES

The objective of this study was to describe the occurrence of lifetime trauma exposure in relation to perinatal health outcomes in low-income African American women.

METHODS

One hundred and sixteen pregnant African American women recruited from two public prenatal clinics participated in this exploratory study. Information was obtained about psychological symptoms, medical conditions, prenatal care utilization, and health behaviors. To measure lifetime trauma exposure, women completed the Trauma History Questionnaire. Maternal and infant outcome data were obtained from the medical records following delivery.

RESULTS

The occurrence of trauma exposure was high, with 87% of the women reporting at least one traumatic event. Their mean age was 25 years, 21% were primiparas, and they reported a mean of 4.3 ± 3.5 (median = 3) traumatic events during their lifetime. Crime-related experiences were common and included incidents of family or friends being murdered or killed (40%), robberies (23%), home burglaries (14%), attacks with weapons (13%), and muggings (12%). Lifetime trauma exposure was significantly associated with depressive symptoms, anxiety, and generalized stress. Women with greater lifetime trauma exposure had a higher rate of tobacco use, higher rate of premature rupture of membranes, and longer maternal hospital stay.

CONCLUSION

Low-income African American women in this sample experienced a variety of traumatic events. Lifetime trauma exposure was associated with adverse perinatal health. Findings suggest the need to further investigate trauma across the lifespan to better understand the impact of these experiences on the reproductive health and well-being of women and their infants.

A thematic analysis of factors influencing recruitment to maternal and perinatal trials

BACKGROUND

Recruitment of eligible participants remains one of the biggest challenges to successful completion of randomised controlled trials (RCTs). Only one third of trials recruit on time, often requiring a lengthy extension to the recruitment period. We identified factors influencing recruitment success and potentially effective recruitment strategies.

METHODS

We searched MEDLINE and EMBASE from 1966 to December Week 2, 2006, the Cochrane Library Methodology Register in December 2006, and hand searched reference lists for studies of any design which focused on recruitment to maternal/perinatal trials, or if no studies of maternal or perinatal research could be identified, other areas of healthcare. Studies of nurses' and midwives' attitudes to research were included as none specifically about trials were located. We synthesised the data narratively, using a basic thematic analysis, with themes derived from the literature and after discussion between the authors.

RESULTS

Around half of the included papers (29/53) were specific to maternal and perinatal healthcare. Only one study was identified which focused on factors for maternal and perinatal clinicians and only seven studies considered recruitment strategies specific to perinatal research. Themes included: participant assessment of risk; recruitment process; participant understanding of research; patient characteristics; clinician attitudes to research and trials; protocol issues; and institutional or organisational issues. While no reliable evidence base for strategies to enhance recruitment was identified in any of the review studies, four maternal/perinatal primary studies suggest that specialised recruitment staff, mass mailings, physician referrals and strategies targeting minority women may increase recruitment. However these findings may only be applicable to the particular trials and settings studied.

CONCLUSION

Although factors reported by both participants and clinicians which influence recruitment were quite consistent across the included studies, studies comparing different recruitment strategies were largely missing. Trials of different recruitment strategies could be embedded in large multicentre RCTs, with strategies tailored to the factors specific to the trial and institution.

Inequities in screening for sexually transmitted infections in African American adolescents: can health policy help?

Although rates of sexually transmitted infections (STIs) in African Americans are higher than other populations, there are disparities in the screening and treatment of STIs for African American adolescents. Many African Americans distrust the health care system, resulting in a reluctance to seek health care. Adolescents may lack access to and the resources to pay for health care. This article reviews historical events believed to influence African American distrust of the health care system, discusses socioeconomic factors influencing adolescent access to services, and offers descriptions of services available to assist adolescents in receiving preventative services. Last, potential health policy solutions for nurses are noted.

Factors associated with loss to follow-up in a large tuberculosis treatment trial (TBTC Study 22)

INTRODUCTION

Loss to follow-up in clinical trials compromises achievement of study goals. We evaluated factors associated with loss to follow-up after completion of treatment phase in a large tuberculosis treatment trial (TBTC/USPHS Study 22) in the U.S. and Canada.

METHODS

Patients who were lost to follow-up were compared to those who reached a study end-point or successfully completed follow-up. A generalized estimating equation model was used to combine patient-specific and site-specific factors.

RESULTS

Of 1075 patients enrolled, 965 (89.8%) reached a study end-point, died, or completed the 2 year post-treatment follow-up phase, and 110 (10.2%) did not. Multivariate analysis showed the following factors to be independently associated with loss to follow-up: birth outside USA/Canada (OR 2.07, 95% CI 1.25-3.40, p=0.005), history of homelessness (OR 1.94, 95% CI 1.00-3.80, p=0.05), enrollment at a health department (OR 2.71, 95% CI 1.27-5.79, p=0.010), and use of any kind of incentive (cash/cash equivalent) during treatment phase (OR 3.04, 95% CI 1.73-5.33 p=0.0001).

CONCLUSIONS

Cultural or linguistic factors and lack of stable housing contribute to loss to follow-up. Attention to these factors could improve long-term retention in clinical trials. Enrollment at a health department and use of incentives during treatment phase may be markers for other factors leading to loss to follow-up.

Recruiting and enrolling pregnant adolescents for research

Difficulty obtaining a sample is not justification for failure to study a hard-to-enroll population, particularly a vulnerable population such as pregnant adolescents. Recruitment of a representative, adequate sample of pregnant adolescents for a recent instrument development study provided multiple challenges. Although carefully developed, the sampling plan required several modifications to achieve the sample (n=145). Those challenges and the ensuing modifications to the sampling plan are discussed in relation to (a) access/institutional concerns, (b) the human subject's protection considerations, and (c) developmental/personal concerns of the pregnant adolescents. Recommendations for sampling strategies for future research are offered.

Participation of disadvantaged parents in child care research

AIM

To assess the level to which parents from deprived and socially dysfunctional families collaborate in complex and time-consuming research.

DESIGN

Home-based study, of early physiological development in infants from a severely deprived area. Overnight continuous recordings of deep-body temperature with twice daily urine collection, parental daily diary of life-events and completion of child care social and psychological assessment by interview questionnaire. Measurements taken between age 6-12 weeks, each lasted 8-12 h per night, averaging four nights per baby. Level of parental participation assessed in relation to ongoing lifestyle pressures. Setting Home based. Inner city deprived estate.

PARTICIPANTS

Random sample of mothers with newborn healthy infants.

MEASUREMENTS

A total of 87 overnight deep body temperature recordings were made on 22 infants each lasting 8-12 h; 174 urine samples were taken; and 22 sets of questionnaires were completed.

RESULTS

Of 62 inner city deprived parents, 39 (62%) agreed to participate. 22 (35%) completed the study. Ongoing lifestyle pressures were high including incidents of burglary, fire and family violence. Family and partner pressures and life crises overwhelmed 10 non-participations.

CONCLUSIONS

Research partnerships can be developed with underprivileged families facing severe life-events. Parents were highly motivated to complete what they perceived as important infant care research.

Ethnicity and recruitment rates in clinical research studies

The concept of a majority population in America is rapidly giving way to a collection of minority populations. To ensure representative study sample populations, nurse researchers must gain the ability to access many culturally and ethnically diverse groups. By examining common challenges to recruitment, many of the pitfalls of minority recruitment may be avoided. In looking at past clinical research studies and evaluating their successes and failures, nurse researchers can gain insight into how to design clinical research studies with sample populations representative of the increasingly diverse American population. Through careful planning, gaining knowledge of target populations, and inventive recruitment methods, the changing face of the American population can be represented in nursing research.
