Telephone Intervention Effect Varied by Race, Health Literacy
DURHAM, NC - Race and health literacy were factors in the effectiveness of a telephone-based osteoarthritis (OA) self-management support intervention, according to a new study.1
Researchers from the Durham, NC, VA Medical Center, Duke University in Durham and the University of North Carolina in Chapel Hill noted that nonwhites with low literacy had the greatest improvement in pain as a result of the intervention.
Study participants included 515 veterans with hip and/or knee osteoarthritis (OA). The effects of the intervention were compared with health education and usual care in assessing levels of pain, function and effect.
Measurement tools included the Arthritis Impact Measurement Scales-2 [AIMS2] and the Visual Analogue Scale. Arthritis self-efficacy ratings also were divided by race, white or nonwhite; health literacy, either high or low; and race by health literacy.
Researchers found that mobility, as measured by AIMS2, improved more among nonwhites than whites in the intervention, compared with health education and usual care (P = 0.02 and 0.008). In terms of pain measured by AIMS2, participants with low, as opposed to high literacy, in the intervention showed more improvement compared with those just receiving health education (P = 0.05).
The intervention had a differential effect on pain, measured by AIMS2, compared with usual care, according to the combination of race and health literacy (P = 0.05), however. Researchers reported that nonwhites with low literacy in the intervention had the greatest improvement in pain.
“This telephone-based OA intervention may be particularly beneficial for patients with OA who are racial/ethnic minorities and have low health literacy,” according to the authors, who added, “These results warrant further research designed specifically to assess whether this type of intervention can reduce OA disparities.”
