Race/Ethnicity and economic differences in cost-related medication underuse among insured adults with diabetes. The TRIAD study.

OBJECTIVE—To examine racial/ethnic and economic variation in cost-related medication underuse among insured adults with diabetes. RESEARCH DESIGN AND METHODS—We surveyed 5,086 participants from the multicenter Translating Research Into Action for Diabetes Study. Respondents reported whether they used less medication because of cost in the past 12 months. We examined unadjusted and adjusted rates of cost-related medication underuse, using hierarchical regression, to determine whether race/ethnicity differences still existed after accounting for economic, health, and other demographic variables. RESULTS—Participants were 48% white, 14% African American, 14% Latino, 15% Asian/Pacific Islander, and 8% other. Overall, 14% reported cost-related medication underuse. Unadjusted rates were highest for Latinos (23%) and African Americans (17%) compared with whites (13%), Asian/Pacific Islanders (11%), and others (15%). In multivariate analyses, race/ethnicity significantly predicted cost-related medication underuse (P = 0.048). However, adjusted rates were only slightly higher for Latinos (14%) than whites (10%) (P = 0.026) and were not significantly different for African Americans (11%), Asian/Pacific Islanders (7%), and others (11%). Income and out-of-pocket drug costs showed the greatest differences in adjusted rates of cost-related medication underuse (15 vs. 5% for participants with income ≤

50 per month. CONCLUSIONS—One in seven participants reported cost-related medication underuse. Rates were highest among African Americans and Latinos but were related to lower incomes and higher out-of-pocket drug costs in these groups. Interventions to decrease racial/ethnic disparities in cost-related medication underuse should focus on decreasing financial barriers to medications.

Behavioral Counseling to Prevent Skin Cancer: US Preventive Services Task Force Recommendation Statement

Objectives: In participatory decision-making (PDM), physicians actively engage patients in treatment and other care decisions. Patients who report that their physicians engage in PDM have better disease self-management and health outcomes. We examined whether physicians’ diabetes-specific treatment PDM preferences as well as their self-reported practices are associated with the quality of diabetes care their patients receive. Methods: 2003 cross-sectional survey and medical record review of a random sample of diabetes patients (n = 4198) in 10 US health plans across the country and their physicians (n = 1217). We characterized physicians’ diabetes care PDM preferences and practices as ‘no patient involvement,’ ‘physician-dominant,’ ‘shared,’ or ‘patient-dominant’ and conducted multivariate analyses examining their effects on the following: (1) three diabetes care processes (annual hemoglobin A1c test; lipid test; and dilated retinal exam); (2) patients’satisfaction with physician communication; and (3) whether patients’ A1c, systolic blood pressure (SBP), and low-density lipoprotein cholesterol (LDL) were in control. Results: Most physicians preferred ‘shared’ PDM (58%) rather than ‘no patient involvement’ (9%), ‘physiciandominant’ (28%) or ‘patient dominant’ PDM (5%). However, most reported practicing ‘physician-dominant’ PDM (43%) with most of their patients, rather than ‘no patient involvement’ (13%), ‘shared’ (37%) or ‘patient-dominant’ PDM (7%). After adjusting for patient and physician-level characteristics and clustering by health plan, patients of physicians who preferred ‘shared’ PDM were more likely to receive A1c tests [90% vs. 82%, AOR: 2.05, 95% CI: 1.03—3.07] and patients of physicians who preferred ‘patient-dominant’ treatment decision-making were more likely to receive lipid tests [60% vs. 50%, AOR: 1.58, 95% CI: 1.04—2.39] than those of providers who preferred ‘no patient involvement’ in treatment decision-making. There were no differences in patients’ satisfaction with their doctor’s communication or control of A1c, SBP or LDL depending on their physicians’ PDM preferences. Physicians’ self-reported PDM practices were not associated with any of the examined aspects of diabetes care in multivariate analyses. Conclusions: Patients whose physicians prefer more patient involvement in decision-making are more likely than patients whose physicians prefer more physician-directed styles to receive some recommended risk factor screening tests, an important first step toward improved diabetes outcomes. Involving patients in treatment decision-making alone, however, appears not to be sufficient to improve biomedical outcomes.

Hormone Therapy for the Primary Prevention of Chronic Conditions in Postmenopausal Women: US Preventive Services Task Force Recommendation Statement

Importance Adults who adhere to national guidelines for a healthful diet and physical activity have lower rates of cardiovascular morbidity and mortality than those who do not. All persons, regardless of their risk status for cardiovascular disease (CVD), can gain health benefits from healthy eating behaviors and appropriate physical activity. Objective To update the 2012 US Preventive Services Task Force (USPSTF) recommendation on behavioral counseling to promote a healthful diet and physical activity for cardiovascular disease prevention among adults without obesity who do not have cardiovascular risk factors (hypertension, dyslipidemia, abnormal blood glucose levels, or diabetes). Evidence Review The USPSTF reviewed the evidence on whether primary care–relevant counseling interventions to promote a healthful diet, physical activity, or both improve health outcomes, intermediate outcomes associated with CVD, or dietary or physical activity behaviors in adults; interventions to reduce sedentary behaviors; and the harms of behavioral counseling interventions. Findings Counseling interventions result in improvements in healthful behaviors and small but potentially important improvements in intermediate outcomes, including reductions in blood pressure and low-density lipoprotein cholesterol levels and improvements in measures of adiposity. The overall magnitude of benefit related to these interventions is positive but small. The potential harms are at most small, leading the USPSTF to conclude that these interventions have a small net benefit for adults without obesity who do not have CVD risk factors. Conclusions and Recommendation The USPSTF recommends that primary care professionals individualize the decision to offer or refer adults without obesity who do not have hypertension, dyslipidemia, abnormal blood glucose levels, or diabetes to behavioral counseling to promote a healthful diet and physical activity. Existing evidence indicates a positive but small benefit of behavioral counseling for the prevention of CVD in this population. Persons who are interested and ready to make behavioral changes may be most likely to benefit from behavioral counseling. (C recommendation)

Vision Screening in Children Aged 6 Months to 5 Years: US Preventive Services Task Force Recommendation Statement

Importance Celiac disease is caused by an immune response in persons who are genetically susceptible to dietary gluten, a protein complex found in wheat, rye, and barley. Ingestion of gluten by persons with celiac disease causes immune-mediated inflammatory damage to the small intestine. Objective To issue a new US Preventive Services Task Force (USPSTF) recommendation on screening for celiac disease. Evidence Review The USPSTF reviewed the evidence on the accuracy of screening in asymptomatic adults, adolescents, and children; the potential benefits and harms of screening vs not screening and targeted vs universal screening; and the benefits and harms of treatment of screen-detected celiac disease. The USPSTF also reviewed contextual information on the prevalence of celiac disease among patients without obvious symptoms and the natural history of subclinical celiac disease. Findings The USPSTF found inadequate evidence on the accuracy of screening for celiac disease, the potential benefits and harms of screening vs not screening or targeted vs universal screening, and the potential benefits and harms of treatment of screen-detected celiac disease. Conclusions and Recommendation The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for celiac disease in asymptomatic persons.

Importance Skin cancer is the most common type of cancer in the United States. Although invasive melanoma accounts for only 2% of all skin cancer cases, it is responsible for 80% of skin cancer deaths. Basal and squamous cell carcinoma, the 2 predominant types of nonmelanoma skin cancer, represent the vast majority of skin cancer cases. Objective To update the 2012 US Preventive Services Task Force (USPSTF) recommendation on behavioral counseling for the primary prevention of skin cancer and the 2009 recommendation on screening for skin cancer with skin self-examination. Evidence Review The USPSTF reviewed the evidence on whether counseling patients about sun protection reduces intermediate outcomes (eg, sunburn or precursor skin lesions) or skin cancer; the link between counseling and behavior change, the link between behavior change and skin cancer incidence, and the harms of counseling or changes in sun protection behavior; and the link between counseling patients to perform skin self-examination and skin cancer outcomes, as well as the harms of skin self-examination. Findings The USPSTF determined that behavioral counseling interventions are of moderate benefit in increasing sun protection behaviors in children, adolescents, and young adults with fair skin types. The USPSTF found adequate evidence that behavioral counseling interventions result in a small increase in sun protection behaviors in adults older than 24 years with fair skin types. The USPSTF found inadequate evidence on the benefits and harms of counseling adults about skin self-examination to prevent skin cancer. Conclusions and Recommendation The USPSTF recommends counseling young adults, adolescents, children, and parents of young children about minimizing exposure to UV radiation for persons aged 6 months to 24 years with fair skin types to reduce their risk of skin cancer. (B recommendation) The USPSTF recommends that clinicians selectively offer counseling to adults older than 24 years with fair skin types about minimizing their exposure to UV radiation to reduce risk of skin cancer. Existing evidence indicates that the net benefit of counseling all adults older than 24 years is small. In determining whether this service is appropriate in individual cases, patients and clinicians should consider the presence of risk factors for skin cancer. (C recommendation) The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of counseling adults about skin self-examination to prevent skin cancer.
