title: Descriptive Analysis of the 2014 Race-Based Healthcare Disparities Measurement Literature.
abstract: OBJECTIVE
  There are more than 500 articles in the 2014 race-based healthcare disparities literature across a broad array of diseases and outcomes. However, unlike many other forms of research (e.g., clinical trials and systematic reviews), there are no required reporting guidelines when submitting results of disparities studies to journals.
  
  
  OBJECTIVE
  This study describes the race-based healthcare disparities measurement literature in terms of study design, journal characteristics, generation of health disparities research, type of disparity measure used, and adherence to disparities measurement guidelines.
  
  
  METHODS
  We searched three databases of peer-reviewed literature, PubMed, Ovid Medline, and JSTOR, for English language articles published in 2014 on racial/ethnic healthcare disparities. Studies must have quantitatively measured the difference in health outcomes between two racial/ethnic groups in order to be included. Our final sample included 266 studies from 167 medical and public health journals.
  
  
  RESULTS
  Only 7 % (n = 19) of articles reported both an absolute and relative measure of disparity; the majority of studies (64 %, n = 171) reported only a relative measure of effect. Most studies were published in clinical journals (74 %, n = 198), used secondary data (86 %, n = 229), and calculated black-white disparities (82 %, n = 218). The most common condition studied was cancer (25 %, n = 67), followed by a surgical procedure (18 %, n = 48). On average, articles in the sample only met 61 % of the applicable guidelines on reporting of disparities.
  
  
  CONCLUSIONS
  To be able to synthesize findings in the racial disparities literature (meta-analysis), there is a need for the use of consistent methods for quantifying disparities and reporting in the literature. A more consistent battery of measures and consistent reporting across studies may help speed our understanding of the origins and development of solutions to address healthcare disparities. Despite guidelines for best practices in reporting disparities, there is a lack of adherence in the current literature.
