Self-reported health risks linked to health plan cost and age group.

BACKGROUND: Studies of private sector employee populations have shown an association between health-risk factors and healthcare costs. Few studies have been conducted on large, public sector employee populations. The objective of the current study was to quantify health plan costs associated with individual tobacco, obesity, and physical inactivity risks in Arkansas's state employee plan. METHODS: De-identified medical and pharmacy claim costs incurred October 1, 2004-February 28, 2006 were linked with results from self-reported health-risk assessments (HRA) completed August 1, 2006-October 31, 2006. High- and no-risk groups were defined on the basis of cigarette use, BMI, and days/week of moderate physical activity. Annualized costs were compared between groups and across ages. Data were analyzed in September 2007. RESULTS: Of the eligible adults (n=77,774), 56% (n=43,461) voluntarily accessed and completed an Internet-based HRA and had claims data-linked for analyses. Average annual costs across the eligible population totaled $3205. Respondents with high risks incurred greater annual costs ($4432) than those with no risks ($2382). Costs were greater among those with one or more risks, compared with no risks, and increased with age. The greatest average annual cost was for people aged 55-64 years in the high-risk group, who had a 2.2-fold higher cost than those aged 55-64 years in the no-risk group ($7233 versus $3266). CONCLUSIONS: Healthcare costs increased with age and were differentially higher for those who used tobacco, were obese, or were physically inactive. The financial viability of the healthcare system is at risk, particularly in plans with a high proportion of adults with health-risk factors.

Quality of care for children in commercial and Medicaid managed care.

CONTEXT: Many states have turned to commercial health plans to serve Medicaid beneficiaries and to achieve cost-containment goals. Assumptions that the quality of care provided to Medicaid beneficiaries through these programs is acceptable have not been tested. OBJECTIVE: To compare the quality of care provided to children and adolescents in commercial and Medicaid managed care in the United States. DESIGN, SETTING, AND POPULATION: Using 1999 data collected through the Health Plan Employer Data and Information Set, we examined reported quality-of-care indicators for children and adolescents. Results from 423 commercial and 169 Medicaid plans were compared. Matched pairs analyses were performed using data from each of the 81 companies serving both populations to control for corporate differences. Correlation coefficients and regression procedures were used to examine observed variations in health plan performance. MAIN OUTCOME MEASURES: Quality indicators including prenatal care, childhood immunizations, well-child visits, adolescent immunizations, and myringotomy and tonsillectomy rates. RESULTS: Using standard indicators of clinical performance, children and adolescents enrolled in Medicaid received worse care compared with their commercial counterparts. For most of the 81 health plans serving both populations, Medicaid enrollees had statistically significantly (P<.001) lower rates than commercial plans for clinical quality indicators (eg, childhood immunization rates of 69% vs 54%); for clinical access indicators (eg, well-child visits in the first 15 months of life, 53% vs 31%); and for common procedures (eg, myringotomies for children aged 0-4 years, 35 vs 2 per 1000 members). Conversely, some plans demonstrated equal and high-quality care for both populations. Regression models failed to identify consistent plan characteristics that explained the observed differences in quality of care. CONCLUSIONS: Most commercial health plans do not deliver high-quality care on a number of performance indicators for children enrolled in Medicaid. Policy makers and the public need plan-specific quality information to inform purchasing decisions.

Health plan quality-of-care information is undermined by voluntary reporting.

BACKGROUND: Most health services in the United States are delivered by managed care organizations (MCOs). Publicly available, plan-specific performance information is required to adequately assess healthcare quality provided. Using women's health indicators, we compared performance results for MCOs and evaluated whether those MCOs that publicly report quality-of-care (QOC) results demonstrate better QOC than those plans that restrict public access to data. METHODS: Data from the Health Plan Employer Data and Information Set (HEDIS) for commercial MCOs in 1998 were analyzed for women's QOC indicators. Plan-specific, regional, and national performances were analyzed and results compared to established benchmarks. Public-reporting plans were compared to plans that restrict access to QOC information. Linear regression was used to identify determinants of health plan performance including public release of information. RESULTS: Commercial MCOs had wide variations in QOC indicators and, on average, failed to attain national health goals for most women's health indicators analyzed. Plans that restricted public access to QOC information had poorer performance than those that did not (p<0.05). Results suggest that whether a plan publicly releases its performance information is highly associated with health plan performance even after taking into account other factors. CONCLUSIONS: The voluntary aspect of reporting and the ability of health plans to restrict public access is allowing poorer performing health plans to escape public scrutiny. Variations in QOC have clinical significance and, if publicly available, would enable individuals to select high-quality healthcare products. The ability of health plans to restrict public information is not consistent with the 1973 Health Maintenance Organization Act requiring public information on health plan quality. A national strategy to ensure that QOC information is available on all healthcare systems is past due.

Differences in health care quality for children and adults under managed care: justification for separate quality assessments?

OBJECTIVE: To assess reported results of health care quality for children and adults in managed systems of care and to determine if variations exist between reported quality results for adults and children within the same plan. METHODS: We utilized Consumer Assessment of Health Plan Survey results reported from 424 managed care plans to the National Committee for Quality Assurance in 1999. Responses from 218 530 adults (515 per plan, 424 plans) and 55 081 parents of children 0-12 years of age (304 per plan, 181 plans) were available. Restricting analyses to the 178 plans reporting both adult and child results, we performed matched-pairs analyses to test the hypothesis that child results would be the same as their adult counterparts within the same plan. Regression methods were employed to test for potential demographic differences explaining observed differences. RESULTS: Within the same plan, reported results for care provided by specialists and primary care physicians to adults and children in the same plan revealed marked variation, including rating of doctor (Spearman correlation coefficient, r(S) =.504) and rating of specialist (r(S) =.326). Conversely, assessments of activities related directly to health plan activities showed little variation, including rating of health plan (r(S) =.850) and claims processing (r(S) =.857). Differences in demographic characteristics between adults and child survey respondents do not appear to explain observed variations. CONCLUSIONS: Separate quality of care assessments for adults and children within the same managed care system identify significant differences in reported quality. Having health plan quality information about adult care does not serve as a proxy for needed information on children, particularly the care related to primary care and specialist providers. Areas of health plan assessment common to both adults and children (eg, claims processing) could be replaced with more targeted assessments of importance to parents and purchasers (eg, children with chronic conditions).
