Smokers eligible for a clinical trial. Correlates of not returning for randomization.
PURPOSE: Recruitment and retention of minority participants is often the rate-limiting step towards successful completion of clinical trials. Participants who are eligible, and express interest in, enrolling into a trial will sometimes not return for their randomization visit. Factors associated with failure to return for randomization are largely unknown.METHODS: We compared 287 eligible African American (AA) smokers who enrolled, but did not return for randomization (NR), to 500 AA smokers who returned and were randomized (R) to participate in a study comparing culturally sensitive educational materials to usual care materials for smoking cessation in AAs. An analysis was conducted on variables potentially associated with not returning for randomization.RESULTS:Table 1CONCLUSIONS: Potential NR participants differed in a number of ways from those who returned for randomization. Better understanding of these factors may allow researchers to target recruitment efforts, potentially resulting in enhanced accrual and retention, and therefore, generalizability.
