Retention of clinical trial participants in a study of nongonococcal urethritis (NGU), a sexually transmitted infection in men

The Effect of a Brief HIV Prevention Program on Risk Reduction Behaviors Among Thai Men Diagnosed With Sexually Transmitted Infections

PURPOSE

Men diagnosed with sexually transmitted infections (STIs) are at greater risk for Human Immunodeficiency Virus (HIV) infection and STIs reinfection. This study aimed to test the effectiveness of a brief human immunodeficiency virus (B-HIV) prevention program on HIV and sexually transmitted infection (STI) knowledge, perceived benefits of condom use, risk reduction self-efficacy, risk reduction behaviors, and reinfection rate among Thai men with STIs.

METHODS

A quasi-experimental design was conducted. Participants were selected from men with STI symptoms. They were randomly assigned to a B-HIV prevention program or usual care, 100 each. The program consisted of 3 modules. Key messages for HIV prevention were sent weekly through Line. Outcomes were HIV and STI knowledge, perceived benefits of condom use, risk reduction self-efficacy, risk reduction behaviors (condom use, the number of sexual partners, and condomless sex), and STI reinfection rate. Independent t-test and binary logistic regression were performed.

RESULTS

The B-HIV prevention program significantly increased HIV and STI knowledge and resulted in perception of greater benefits from condoms and greater risk reduction self-efficacy. Program participants used condoms more frequently with many types of partners, especially with casual partners and sex workers. The intervention group practiced condomless sex less frequently than the control group. The program did not improve participants' condom use with lovers/steady partners and did not decrease the number of sexual partners and STI reinfection rate at 3-month follow-up.

CONCLUSIONS

A B-HIV prevention program could reduce the risk of HIV infection among male clients with current STIs by enhancing their condom use with casual partners and sex workers. Strategies to improve condom use with lovers/steady partners among this high-risk population is needed.

Predictors of participant retention in infertility treatment trials

OBJECTIVE

To identify variables associated with retention (or dropout) in infertility clinical trials. Retention of subjects in randomized controlled clinical trials (RCTs) has received considerable attention, but there have been few consistent findings.

DESIGN

Secondary analysis of data from RCTs.

SETTING

Academic medical centers.

PATIENT(S)

Women with polycystic ovary syndrome (PCOS) or couples with unexplained infertility, aged 18-40 years.

INTERVENTION(S)

This study is not an intervention study, but the patients in the original RCTs were treated with any or combination of metformin, clomiphene citrate (CC), letrozole, and gonadotropins.

MAIN OUTCOME MEASURE(S)

Successful retention versus dropout during the RCTs.

RESULT(S)

Race, ethnicity, body mass index (BMI), insurance coverage, history of smoking, and history of alcohol use were significantly associated with retention whether they were considered in bivariate analyses or a multivariable logistic model. Specifically, white race, higher income, having graduate degrees, normal weight, better insurance coverage, nonsmokers, and those who reported current use of alcohol at the start of the trial, had higher retention rates.

CONCLUSION(S)

We identified several additive and persistent predictors of retention that can be used to guide the conduct of RCTs and improve the retention rate. Given the limitation of our association analysis, methodologically sound and theoretically grounded research are warranted so that high quality data can be collected to improve our understanding on the causes of dropout.

An Electronic Asthma Self-Management Intervention for Young African American Adults

BACKGROUND

Health disparities are seen in many chronic conditions including asthma. Young African American adults represent a population at high risk for poor asthma outcomes due to both their minority status and the difficult transition from adolescence to adulthood. Recruitment and retention has been challenging in this demographic stratum, and traditional asthma education is often not feasible.

OBJECTIVE

The objective of this study was to develop and assess the feasibility of an electronic asthma self-management program for young African American adults.

METHODS

A total of 44 African American adults (age 18-30 years) with uncontrolled persistent asthma were enrolled in an asthma self-management program. The 6-week Breathe Michigan program (predicated on the social cognitive theory) was tailored specifically to the concerns and preferences of young African American adults. The entire program was completed electronically, without any specialized human support. At 2 weeks and 3 months after program completion, participants were contacted for follow-up.

RESULTS

A total of 89% of enrolled subjects completed the 6-week intervention, and 77% were available for evaluation at 3 months. All subjects completing the 2-week postprogram survey reported that the program was helpful, and 97% would recommend it to others. Asthma control as measured by the Asthma Control Test improved from 16.1 to 19.3 (P < .01), and asthma quality of life as measured by the Mini Asthma Quality of Life Questionnaire improved from 4.0 to 5.1 (P < .01).

CONCLUSIONS

The Breathe Michigan program is feasible for recruitment and retention, and demonstrated an improvement in asthma control and quality of life for young African American adults.

Feasibility and acceptability of SMS text messaging in a prostate cancer educational intervention for African American men

African Americans' greater access to mobile phones makes short messaging service technology a promising complement to health promotion interventions. Short messaging service text messages were added to the Men's Prostate Awareness Church Training project, a men's health intervention for African American men. We report on the feasibility and acceptability of the use of short messaging service text messages in the intervention. Short messaging service text messages served as (1) workshop reminders; (2) post-workshop message reinforcement; (3) spiritual/motivational messages; and (4) participant retention. At workshop 4, over 65 percent of participants wished to continue receiving the messages. While there was an increase in recall over time, more than one-third of the participants did not recall receiving the 53 text messages. However, recall was considerably greater among men who attended the Men's Prostate Awareness Church Training workshops. Overall, the inclusion of text messages in health promotion interventions targeting mature African American men was found to be feasible and acceptable.

The Use of Technology in Participant Tracking and Study Retention: Lessons Learned From a Clinical Trials Network Study

BACKGROUND

The growing use of newer communication and Internet technologies, even among low-income and transient populations, require research staff to update their outreach strategies to ensure high follow-up and participant retention rates. This paper presents the views of research assistants on the use of cell phones and the Internet to track participants in a multisite randomized trial of substance use disorder treatment.

METHODS

Preinterview questionnaires exploring tracking and other study-related activities were collected from 21 research staff across the 10 participating US sites. Data were then used to construct a semistructured interview guide that, in turn, was used to interview 12 of the same staff members. The questionnaires and interview data were entered in Atlas.ti and analyzed for emergent themes related to the use of technology for participant-tracking purposes.

RESULTS

Study staff reported that most participants had cell phones, despite having unstable physical addresses and landlines. The incoming call feature of most cell phones was useful for participants and research staff alike, and texting proved to have additional benefits. However, reliance on participants' cell phones also proved problematic. Even homeless participants were found to have access to the Internet through public libraries and could respond to study staff e-mails. Some study sites opened generic social media accounts, through which study staff sent private messages to participants. However, the institutional review board (IRB) approval process for tracking participants using social media at some sites was prohibitively lengthy. Internet searches through Google, national paid databases, obituaries, and judiciary Web sites were also helpful tools.

CONCLUSIONS

Research staff perceive that cell phones, Internet searches, and social networking sites were effective tools to achieve high follow-up rates in drug abuse research. Studies should incorporate cell phone, texting, and social network Web site information on locator forms; obtain IRB approval for contacting participants using social networking Web sites; and include Web searches, texting, and the use of social media in staff training as standard operating procedures.
