Catalyzing quality of care improvements for women

Germain A, Egede LE. Trends in sex differences in the receipt of quality of care indicators among adults with diabetes: United States 2002-2011

BACKGROUND

Evidence suggests disparities in quality of care (QoC) indicators based on sex exist in adults diagnosed with diabetes; however, this research is limited. Therefore, the objective of this research study was to assess differences in QOC indicators in a nationally representative sample of men and women with diabetes.

METHODS

Cross-sectional study of 17,702 men and women (≥18 years of age) with diabetes from the 2002-2011 Medical Expenditure Panel Survey Household Component. Sex was the main predictor variable, and the dependent variables were five binary indicators to measure QOC, which included testing of hemoglobin A1c, examining feet annually, getting eyes dilated, checking blood pressure, and visiting the doctor annually. Sample demographics by sex were assessed. Unadjusted analyses were computed for descriptive statistics by sex and proportions of QOC indicators over time. Logistic regression evaluated associations between QOC indicators and sex, while controlling for sociodemographic characteristics, time, and comorbid conditions.

RESULTS

Approximately 44% and 56% of the sample was comprised of men and women, respectively. Unadjusted analyses showed significant differences in A1c testing (p < 0.001) and foot examinations (p = 0.002) for the entire sample, and significant differences in A1c testing (p = 0.027), foot examinations (p = 0.01), and dilated eye exams (p = 0.026) among men and A1c testing (p < 0.001) among women overtime. Adjusted analyses found women to be significantly more likely to have dilated eye examinations during a given year (OR = 1.14; 95% CI 1.04, 1.24), to get their blood pressure checked by a doctor in a given year (OR = 1.44; 95% CI 1.13, 1.84), and to visit a doctor annually (OR = 1.39; 95% CI 1.22, 1.58) compared to men.

CONCLUSIONS

In this sample of adults with diabetes, women had significantly higher odds of receiving quality of care compared to men. These findings suggest the importance of educating patients about appropriate metrics of diabetes management, especially men, and the need for continuous empowerment of women to receive proper and optimal care. Additional research is needed to identify causes and reduce sex and gender disparities associated with diabetes quality of care.

Gender Disparities in the Quality of Cardiovascular Disease Care in Private Managed Care Plans

BACKGROUND

Studies have shown that women with cardiovascular disease (CVD) are screened and treated less aggressively than men and are less likely to undergo cardiac procedures. Research in this area has primarily focused on the acute setting, and there are limited data on the ambulatory care setting, particularly among the commercially insured. To that end, the objective of this study is to determine if gender disparities in the quality of CVD care exist in commercial managed care populations.

METHODS

Using a national sample of commercial health plans, we analyzed member-level data for 7 CVD quality indicators from the Healthcare Effectiveness Data and Information Set (HEDIS) collected in 2005. We used hierarchical generalized linear models to estimate these HEDIS measures as a function of gender, controlling for race/ethnicity, socioeconomic status, age, and plans' clustering effects.

RESULTS

Results showed that women were less likely than men to have low-density lipoprotein (LDL) cholesterol controlled at <100 mg/dL in those who have diabetes (odds ratio [OR], 0.81; 95% confidence interval [CI], 0.76-0.86) or a history of CVD (OR, 0.72; CI 95%, 0.64-0.82). The difference between men and women in meeting the LDL control measures was 5.74% among those with diabetes (44.3% vs. 38.5%) and 8.53% among those with a history of CVD (55.1% vs. 46.6%). However, women achieved higher performance than men in controlling blood pressure (OR, 1.12; 95% CI, 1.02-1.21), where the rate of women meeting this quality indicator exceeded that of men by 1.94% (70.8% for women vs. 68.9% for men).

CONCLUSIONS

Gender disparities in the management and outcomes of CVD exist among patients in commercial managed care plans despite similar access to care. Poor performance in LDL control was seen in both men and women, with a lower rate of control in women suggesting the possibility of less intensive cholesterol treatment in women. The differences in patterns of care demonstrate the need for interventions tailored to address gender disparities.

Gender and racial disparities in the management of diabetes mellitus among Medicare patients

BACKGROUND

Racial/ethnic disparities in diabetes care have been demonstrated in several settings, but few studies have evaluated whether racial/ethnic differences vary by gender. The objective of this study is to understand gender and racial effects on diabetes care for Medicare managed care beneficiaries.

METHODS

Using data from: (1) Healthcare Effectiveness Data and Information Set (HEDIS); (2) Medicare Enrollment Files; and (3) U.S. Census, hierarchical generalized linear analyses were conducted to model the six HEDIS comprehensive diabetes care quality indicators, including processes of care and intermediate outcome measures, as a function of gender and race/ethnicity.

RESULTS

Women were more likely to have received HbA(1c) screening or eye examination, but less likely to have LDL control at <100 mg/dL, compared to men. Racial disparities favored whites in five measures, where African Americans were less likely to have received HbA(1c) screening, eye examination, cholesterol screening, or achieve adequate HbA(1c) control or LDL control at <100 mg/dL. Enrollees in managed care plans where African Americans constituted more than 20% of their insured population tended to have lower likelihood of meeting the HbA(1c) screening, HbA(1c) control, and eye examination measures.

CONCLUSIONS AND DISCUSSION

Gender and racial disparities in performance indicators were present among persons enrolled in Medicare managed care. White women were more likely to have met the performance measures related to process of care, but African Americans fared worse in both process of care and intermediate health outcome measures, compared to their white counterparts. Poor performance in cholesterol control observed in women of both races suggests the possibility of less intensive cholesterol treatment in women. The differences in the pattern of care demonstrate the need for interventions tailored to address gender and race/ethnicity.
