Ences have also been associated with perception of treatment benefits. Racial and ethnic variations in willingness to undergo knee replacement were highly attributed to patient expectations about procedure success in a cohort of OA patients [9]. In a separate study, African-American OA patients’ reluctance to consider joint replacement wasattributed to their expectations of hospital course, pain and function following surgery [10]. These findings suggest patient beliefs may be influenced by patient education, as well as by improved physicianpatient interactions [25]. Poor responses to standard drugs by AfricanAmericans with lupus make participation in clinical trials vital [26, 27]. The literature is contradictory on whether African-Americans are as willing to participate in health research as non-Hispanic whites [2831]. In our study, fewer African-Americans than whites expressed a willingness to participate in a clinical trial, but this difference was not statistically significant. A type II error may explain this lack of significance because the racial/ethnic difference was actually quite large (80.7 vs 68.7 ). The estimated power for the comparison of proportions of African-American and white SLE patients willing to participate in a clinical trial in our study was small (0.31) and a larger sample size may have yielded a significant result. We found that the major determinants of preferences for participation in a lupus clinical trial included CV205-502 hydrochlorideMedChemExpress CV205-502 hydrochloride internal health locus of control and marital status. Understandably, a lowwww.rheumatology.oxfordjournals.orgErnest R. Vina et al.sense of internal control over one’s health may predict a higher likelihood of voluntary participation in a research trial involving an experimental medication. On the other hand, the presence of a partner may encourage participation, knowing that a support system is available in the event of an adverse outcome. Other determinants of SLE clinical trial participation included high perceived physician PDM style and lack of physician race preference. Indeed, greater physician PDM and patient-centred care have both been associated with better patient satisfaction and patient compliance [32]. In addition, African-Americans were found to be less willing to participate in research if they attribute high importance to physician race when seeking routine medical care [28]. In our cohort, African-American and white SLE patients differed in several ways. Specifically, African-American participants had less education, lower household incomes, and higher co-morbidity and depression scores than white participants. Similar racial/ethnic differences have been seen in other SLE cohorts [1, 33, 34]. In contrast to other SLE cohorts [35, 36], however, lupus disease activity and damage index scores were not significantly AUY922 chemical information different between racial/ethnic groups in our study. This may be due to the fact that only lupus patients in the outpatient clinic were recruited. In this setting, lupus patients with more severe disease may have been less inclined to participate in the study. African-American SLE patients were more likely to acknowledge the helpfulness of prayer in the treatment of the disease, not unlike African-American OA patients [37]. Compared with whites, African-American lupus patients were also more likely to believe that the outcomes of their disease could be attributed by their own actions and by powerful others such as family, friends and medical professionals.
