Eliminating disparities in health can benefit from the inclusion of diverse populations pursuing health disparity research careers. A goal of the Texas Center for Health Disparities (TCHD) is to provide opportunities for underrepresented minority faculty to become successful health disparity researchers. The TCHD created the Steps Toward Academic Research (STAR) fellowship program to provide faculty and community partners a yearlong face-to-face and online hybrid curriculum focused on acquiring fundamental concepts in biomedical and behavioral health disparity research, basics in grantsmanship as well as professional development skills. In total, this training approach is envisioned to provide mutually beneficial co-learning experiences that will increase the number of under-represented minorities (URMs) entering translational research focused on the elimination of health disparities.

Background: The extent to which trial-level factors differentially influence accrual to trials has not been comprehensively studied. Our objective was to evaluate the empirical relationship and predictive properties of putative risk factors for low accrual in the National Cancer Institute's (NCI's) Cooperative Group Program, now the National Clinical Trials Network (NCTN).Methods: Data from 787 phase II/III adult NCTN-sponsored trials launched between 2000 and 2011 were used to develop a logistic regression model to predict low accrual, defined as trials that closed with or were accruing at less than 50% of target; 46 trials opened between 2012 and 2013 were used for prospective validation. Candidate predictors were identified from a literature review and expert interviews; final predictors were selected using stepwise regression. Model performance was evaluated by calibration and discrimination via the area under the curve (AUC). All statistical tests were two-sided.Results: Eighteen percent (n = 145) of NCTN-sponsored trials closed with low accrual or were accruing at less than 50% of target three years or more after initiation. A multivariable model of twelve trial-level risk factors had good calibration and discrimination for predicting trials with low accrual (AUC in trials launched 2000-2011 = 0.739, 95% confidence interval [CI] = 0.696 to 0.783]; 2012-2013: AUC = 0.732, 95% CI = 0.547 to 0.917). Results were robust to different definitions of low accrual and predictor selection strategies.Conclusions: We identified multiple characteristics of NCTN-sponsored trials associated with low accrual, several of which have not been previously empirically described, and developed a prediction model that can provide a useful estimate of accrual risk based on these factors. Future work should assess the role of such prediction tools in trial design and prioritization decisions. [ABSTRACT FROM AUTHOR]

Background: America's racial and ethnic composition is changing so rapidly that minority groups are expected to constitute almost half of the U.S. population by 2060. Special efforts are needed to effectively recruit and retain members of racial and ethnic minority groups in health-related research studies, but the information available on time and costs associated with their recruitment is limited. Objectives: The aim of this study was to describe and compare the time and monetary costs associated with recruiting and interviewing a diverse sample of older adults living in south Florida. Methods: Men and women aged 60 years and older from four ethnic groups-African American, Afro-Caribbean, Hispanic American, and European American-were recruited to participate in a longitudinal study of healthy aging. Costs for study activities (including recruitment, scheduling sessions, interviewing, file scoring, log updating, blood specimen analysis and storage, data analysis, and monetary compensation to participants) were determined after 100 weeks of data collection. Results: Altogether, 483 participants completed the study in the first 100 weeks. The total cost for each participant ranged from $265 to $576. Each successful enrollment required an average of 1.83 hours for recruitment and scheduling of the interviews. The time to interview African American and Afro-Caribbeans was greater than the time needed to interview Hispanic American and European American participants. Discussion: To develop more accurate budgets for recruitment of minority individuals into research studies and to use the limited resources in an effective way, careful planning and ongoing monitoring of costs are essential.

Comparative effectiveness research (CER) has the potential to slow health care spending growth by focusing resources on health interventions that provide the most value. In this article, we discuss issues surrounding CER and its implementation and apply these methods to a salient clinical example: treatment of prostate cancer. Physicians have several options for treating patients recently diagnosed with localized disease, including removal of the prostate (radical prostatectomy), treatment with radioactive seeds (brachytherapy), radiation therapy (IMRT), or--if none of these are pursued--active surveillance. Using a commercial health insurance claims database and after adjustment for comorbid conditions, we estimate that the additional cost of treatment with radical prostatectomy is $7,300, while other alternatives are more expensive--$19,000 for brachytherapy and $46,900 for IMRT. However a review of the clinical literature uncovers no evidence that justifies the use of these more expensive approaches. These results imply that if patient management strategies were shifted to those supported by CER-based criteria, an estimated $1.7 to $3.0 billion (2009 present value) could be saved each year.

We describe past NIH funding for tobacco/nicotine-related research, using data from the CRISP computerized database of NIH grants awarded in 1975, 1980, 1985, 1990, and 1995 (last year available). Two independent raters identified extramural grants whose investigators listed a nicotine/tobacco-related keyword as a primary descriptor for 1975, 1980, 1985, 1990, and 1995. From 1975 to 1985 extramural funding for nicotine/tobacco research (corrected for inflation) increased almost fourfold. From 1985 to 1995, funding increased minimally (< 20%). In 1995, NIH expended $92.1 million on research whose primary interest was nicotine or tobacco. This represented 1.1% of the overall NIH extramural budget. Over time, when contract funding increased, investigator-initiated R01 funding decreased. Nicotine/tobacco research was spread across 18 institutes. Although tobacco use accounts for 20% of all US mortality, historically only 1% of the NIH's budget has focused on nicotine or tobacco. Among nicotine/tobacco grants funded, investigator-initiated research appears to have been limited due to large contracts for clinical trials. Nicotine/tobacco research has no home institute. Funding for nicotine/tobacco research needs to be increased and better coordinated. [ABSTRACT FROM AUTHOR]
