ABSTRACT
Differences in preference-weighted health-related quality of life (HRQOL) scores by race/ethnicity may be due to social factors. Here, Short-Form Six-Dimension (SF-6D) scores are analyzed among men in a prostate cancer prevention trial to explore such differences. Selenium and vitamin E cancer prevention trial participants who completed the SF-6D at baseline, and in at least 1 of follow-up years 1, 3, and 5 were included. This study compared mean SF-6D scores across race/ethnicity at each point using a linear mixed model controlling for demographic and clinical characteristics. At baseline, 9691 men were eligible for analysis, of whom 7556 (78%) were non-Hispanic White, 1592 (16.4%) were non-Hispanic Black, and 543 (5.6%) were Hispanic. Hispanic and White participants had higher unadjusted mean SF-6D scores than Black participants at every time point (P < 0.05), while white participants had lower mean scores than Hispanic participants at every time point after baseline (P < 0.05). After adjusting for covariates, statistically significant differences in HRQOL among the 3 groups persisted. Hispanic participants had higher preference scores than White participants by 0.073 (P < 0.001), 0.075 (P < 0.001), and 0.040 (P < 0.001) in follow-up years 1, 3, and 5, respectively. Black participants had lower scores than White participants by 0.009 (P = 0.004) and 0.008 (P = 0.02) in follow-up years 1 and 3, respectively. The results suggest there is a preference-weighted HRQOL difference by race/ethnicity that cannot be explained by social and clinical variables alone. Understanding how individuals belonging to different racial/ethnic categories view their own HRQOL is necessary for culturally competent care and cost-effectiveness analyses.
ABSTRACT
PURPOSE: An ostomy introduces to cancer survivors new demands for self-care and healthcare resource use. A curriculum that teaches ostomates self-management skills may affect survivors' use of resources. METHODS: A prospective randomized trial comparing usual care (UC) with an Ostomy Self-Management Training (OSMT) program delivered by telehealth was conducted in patients with ostomies due to cancer. The intervention occurred over 5 weeks with survey administration at baseline, program completion, and 6 months after completion. Quantitative data were analyzed using a mixed-effects logistic model to predict mean values of resource and service use. Responses to the open-ended question were coded and analyzed with directed content analysis. RESULTS: One hundred and sixty-seven subjects (89 in the OSMT arm and 78 in the UC arm) completed the questionnaire at all time points. The changes in likelihoods of emptying one's ostomy bag > 8 times/week and of incurring any out-of-pocket costs on accessories were 14% greater for the intervention group (p = .029 and p = .063, respectively). Qualitative analysis reveals among the OSMT arm an increase in the proportion of ostomy-specific comments and a decrease in the same metric among the UC arm. Common themes included learning to work with equipment, dealing with gas build-up and finding well-fitting clothing. CONCLUSIONS: There are some indications that participants in this structured telehealth program are more active in ostomy self-care. The reported ostomy self-care activities, healthcare consumables, and healthcare services reported by both groups illustrate the complexity of survivorship care following ostomy surgery.
