RESUMO

Immigrants have lower and disproportionate use of preventive care. We use longitudinal panel data to examine how the 2014 full implementation of the ACA mandates affected change in preventive services (PS) use among immigrants that gained insurance. We used data on Foreign-Born (FB) and US-Born (USB) adults, ages 26-64 years, from the 2013/16 Medical Expenditures Panel Survey longitudinal files to examine within-person change in yearly utilization of age/sex specific United States Preventive Services Task Force (USPSTF) recommended services. We included five primary care (e.g., influenza immunization), three behavioral (e.g., diet), and seven cancer screening (e.g., mammography) measures. We used generalized estimating equations and difference-in-differences tests to assess the effects of insurance gain on: (1) change in PS utilization, and (2) reduction in utilization disparities between USB and FB adults, adjusting for predisposing, health enabling, and health needs factors. Our results showed that newly-insured FB adults substantially increased their use of all primary care checks, and exercise and diet advice. We also found improvements in use of endoscopies, two modalities of colon cancer screening, and prostate cancer screening, but not in receipt of mammography and clinical breast exams. Newly-insured FB PS use remained lower than use among continuously-insured USB adults, but some of the differences were explained by adjustment to enabling and health needs factors. Briefly, health insurance gains among immigrants translated into substantial improvements in use of recommended PS. Still, notable disparities persist among the newly-insured FB, and more so among the 1 in 5 that remain continuously uninsured.

RESUMO

OBJECTIVES: To examine whether racial/ethnic differences in mortality rates have changed in recent years among adults in late midlife, and if so, how. METHODS: We analyze Health and Retirement Study data on non-Hispanic Whites (Whites), non-Hispanic Blacks (Blacks), and English- and Spanish-speaking Hispanics (Hispanic-English and Hispanic-Spanish), aged 50-64 from 2 periods: 1998-2004 (Period 1, n = 8,920) and 2004-2010 (Period 2, n = 7,224). Using survey-generalized linear regression techniques, we model death-by-end-of-period as a function of race/ethnicity and sequentially adjust for a series of period-specific baseline risk factors including demographics, health status, health insurance, health behaviors, and social networks. Regression decomposition techniques are used to assess the contribution of these factors to observed racial/ethnic differences in mortality rates. RESULTS: The odds ratio for death (ORD) was not statistically different for Blacks (vs. Whites) in Period 1 but was 33% higher in Period 2 (OR = 1.33; 95% confidence interval [CI] = 1.05-1.69). The adjusted ORD among Hispanic-English (vs. Whites) was not statistically different in both periods. The adjusted ORD among Hispanic-Spanish (vs. Whites) was lower (ORD = 0.36; 95% CI = 0.22-0.59) in Period 1 but indistinguishable in Period 2. In Period 1, 50.1% of the disparity in mortality rates among Blacks was explained by baseline health status, 53.1% was explained by financial factors. In Period 2, 55.8% of the disparity in mortality rates was explained by health status, 40.0% by financial factors, and 16.2% by health insurance status. DISCUSSION: Mortality rates among Blacks and Hispanic-Spanish have risen since the mid-1990s. Hispanic-Spanish may be losing their advantageous lower risk of mortality, long known as the "Hispanic Paradox."

RESUMO

OBJECTIVES: Immigrants to the USA have disparate access to health insurance coverage and healthcare services. We evaluate the effects of gaining insurance following the January 2014 Affordable Care Act's (ACA) key provisions implementation on health services use among foreign- (FB) and US-born (USB) adults. METHODS: Longitudinal data from two panels (2013/2014 and 2014/2015) of the Medical Expenditure Panel Survey on FB and USB adults, ages 26-64 (unweighted n = 15,232), and difference-in-differences analysis using generalized estimating equations were used to estimate the effects of insurance gain. The primary outcomes were five measures of healthcare utilization including yearly routine care appointment, annual number of physician office visits, annual number of prescription medications filled or refilled, use of the emergency department (ED) during the year, and having an inpatient hospital stay during the year. RESULTS: Immigrants were more likely to gain health insurance between 2013 and 2015 relative to USB adults (6.3% vs. 4.4%) but remained much more likely to be continuously uninsured by 2015 (20.8% vs. 6.4%). Controlling for sociodemographic and health characteristics, FB and USB adults who gained insurance increased their use of health services, including routine care (absolute change ΔFB = 15.7%; p < 0.001 and ΔUSB = 11.7%; p < 0.001), office-based doctor visits (ΔFB = 1.3; p < 0.001 and ΔUSB = 0.6; p < 0.001), prescribed medications (ΔFB = 2.5; p < 0.001 and ΔUSB = 1.6; p = 0.016), and inpatient hospitalizations (ΔFB = 3.6%; p = 0.017 and ΔUSB = 3%; p < 0.001). ED use increased only among the FB (ΔFB = 4.8%; p < 0.001). Gaining insurance eliminated the differences in health services use for all considered outcomes among the FB relative to the continuously insured USB. CONCLUSIONS: US immigrants had notable gains in health insurance after the ACA provisions took full effect, but major disparities in coverage persist. If insurance continues to expand among immigrants, then the gains may reduce longstanding disparities in health services use and enhance primary and preventive healthcare.

RESUMO

OBJECTIVES: In the United States the percentage of Medicaid enrollees in some form of Medicaid managed care has increased more than seven-fold since 1990, e.g., up from 11% in 1991 to 82% in 2017. Yet little is known about whether and how this major change in Medicaid insurance affects how recipients use hospital emergency rooms. This study compares the performance of Medicaid health maintenance organizations (HMOs) and fee-for-service (FFS) Medicaid regarding the occurrence of potentially preventable emergency department (ED) use. METHODS: Using data from the 2003-2015 Medical Expenditure Panel Survey (MEPS), a nationally representative survey of the non-institutionalized US population, we estimated multivariable logistic regression models to examine the relationship between Medicaid HMO status and potentially preventable ED use. To accommodate the composition of the Medicaid population, we conducted separate repeated cross-sectional analyses for recipients insured through both Medicaid and Medicare (dual eligibles) and for those insured through Medicaid only (non-duals). We explicitly addressed the possibility of selection bias into HMOs in our models using propensity score weighting. RESULTS: We found that the type of Medicaid held by a recipient, i.e., whether an HMO or FFS coverage, was unrelated to the probability that an ED visit was potentially preventable. This finding emerged both among dual eligibles and among non-duals, and it occurred irrespective of the adopted analytical strategy. CONCLUSIONS: Within the U.S. Medicaid program, Medicaid HMO and FFS enrollees are indistinguishable in terms of the occurrence of potentially preventable ED use. Policymakers should consider this finding when evaluating the pros and cons of adopting Medicaid managed care.

RESUMO

Since 2011, the Affordable Care Act (ACA) requires the provision of certain recommended clinical preventive services without cost-sharing for individuals in Medicare. We re-visited the effects of the ACA on preventive services utilization under Medicare, using data from the Medical Expenditure Panel Survey (MEPS) and examined the ACA's longer-term effects on preventive services utilization among Medicare beneficiaries. We analyzed nationally representative data on non-institutionalized Medicare beneficiaries (n = 27,124) from the 2006-2010 and 2012-2016 Medical Expenditure Panel Survey. Preventive services of interest were cholesterol test, blood pressure test, flu shot, endoscopy, blood stool test, clinical breast exam, mammography and prostate exam. We estimated propensity score weighted difference-in-difference (DID) models to test for differences in preventive services utilization based on Medicare insurance status. Nationwide, among beneficiaries with traditional Medicare only, who stood to gain the most from eliminating cost-sharing for preventive services, the percentage of women receiving clinical breast exams rose post-reform (Δ = 8.1%; p < 0.015) as compared to Medicare beneficiaries with supplemental private coverage, while at the same time the percentage receiving other preventive services did not change post-reform (all p > 0.05). Based on this analysis of MEPS data spanning 2006-2016, the ACA's enhancement of Medicare coverage had only modest effects on the percentage of beneficiaries receiving a range of preventive services. Medicare beneficiaries should be better informed of the availability of these services and encouraged by their physicians to avail the no cost-sharing incentive of these reforms.

RESUMO

OBJECTIVES: A well-documented paradox is that Hispanics tend to live longer than non-Hispanic Whites (NHW), despite structural disadvantages. We evaluate whether the "Hispanic paradox" extends to more comprehensive longitudinal aging classifications and examine how lifecourse factors relate to these groupings. METHODS: We used biennial data (1998-2014) on adults aged 65 years and older at baseline from the Health and Retirement Study. We use joint latent class discrete time and growth curve modeling to identify trajectories of aging, and multinomial logit models to determine whether U.S.-born (USB-H) and Foreign-born (FB-H) Hispanics experience healthier styles of aging than non-Hispanic Whites (NHW), and test how lifecycle factors influence this relationship. RESULTS: We identify four trajectory classes including, "cognitive unhealthy," "high morbidity," "nonaccelerated", and "healthy." Compared to NHWs, both USB-H and FB-H have higher relative risk ratios (RRR) of "cognitive unhealthy" and "high morbidity" classifications, relative to "nonaccelerated." These patterns persist upon controlling for lifecourse factors. Both Hispanic groups, however, also have higher RRRs for "healthy" classification (vs "nonaccelerated") upon adjusting for adult achievements and health behaviors. DISCUSSION: Controlling for lifefcourse factors USB-H and FB-H have equal or higher likelihood for "high morbidity" and "cognitive unhealthy" classifications, respectively, relative to NHWs. Yet, both groups are equally likely of being in the "healthy" group compared to NHWs. These segregations into healthy and unhealthy groups require more research and could contribute to explaining the paradoxical patterns produced when population heterogeneity is not taken into account.

RESUMO

INTRODUCTION: The objective of this study is to compare the performance of Medicaid health maintenance organizations (HMOs) and fee-for-service (FFS) Medicaid regarding the prevalence of potentially preventable hospitalizations, a recognized measure of outpatient care quality. METHODS: This study used nationally representative data on non-institutionalized Medicaid recipients, ages 18-64, from the 2003-2012 Medical Expenditure Panel Survey. Separate analyses are conducted for recipients insured through both Medicaid and Medicare ("dual eligibles") and recipients whose only health insurance is Medicaid ("non-duals"). In each group the occurrence of potentially preventable hospitalizations is measured, and then survey-weighted multivariable logistic regression models are fit to quantify the relationship between Medicaid HMO status and the occurrence of such stays. The possibility of selection bias into HMOs is considered and explicitly addressed in model estimation using propensity score methods. RESULTS: Adjusting for covariates and confounders dual eligible enrolled in Medicaid managed care are more likely to have a potentially preventable hospitalization relative to those covered under FFS Medicaid (survey weighted logit model OR = 1.72, 95% CI = 0.98-3.03; propensity score weighted logit model OR = 1.87, 95% CI = 1.06-3.28). In contrast, the odds ratios did not differ among non-duals in Medicaid HMOs versus FFS Medicaid. CONCLUSION: These findings suggest that, at least for dual eligibles, the quality of outpatient care in Medicaid HMOs may be worse than under FFS Medicaid. Better and more streamlined clinical preventive approaches for this high risk and vulnerable population might be required in Medicaid HMOs.

RESUMO

This article examines whether adverse changes to health or functioning serve as an impetus to begin using preventive services among older individuals with a history of non-use. Using data from the 1998-2008 Health and Retirement Study, the use of mammograms, pap smears, prostate cancer screenings, cholesterol checks, and flu shots is examined among 2,975 self-reported non-users of such services. Older women who experience a health shock are 1.86, 1.50, 1.79, and 1.46 times more likely to begin getting mammograms, pap smears, cholesterol checks, and flu shots, respectively. Older men who experience a health shock are 2.24, 2.72, and 1.64 times more likely to begin getting prostate cancer screenings, cholesterol checks, and flu shots, respectively. All of these results are statistically significant. Thus, older adults often improve their health behaviors after experiencing an adverse health event.

RESUMO

This article examines the determinants of healthy aging using Grossman's framework of a health production function. Healthy aging, sometimes described as successful aging, is produced using a variety of inputs, determined in early life, young adulthood, midlife, and later life. A healthy aging production function is estimated using nationally representative data from the 2010 and 2012 Health and Retirement Study on 7,355 noninstitutionalized seniors. Using a simultaneous equation mediation model, we quantify how childhood factors contribute to healthy aging, both directly and indirectly through their effects on mediating adult outcomes. We find that favorable childhood conditions significantly improve healthy aging scores, both directly and indirectly, mediated through education, income, and wealth. We also find that good health habits have positive effects on healthy aging that are larger in magnitude than the effects of childhood factors. Our findings suggest that exercising, maintaining proper weight, and not smoking are likely to translate into healthier aging.

RESUMO

In January 2005, Medicare began covering a one-time initial preventive physical examination (IPPE), also called a "Welcome-to-Medicare" visit, during a beneficiary's first 6 months under Part B. This paper examines the effects of offering Medicare IPPE coverage on the use of mammograms, breast self-exams, Pap smears, prostate cancer screenings, cholesterol screenings, and flu vaccines among beneficiaries new to Part B. We adopt a difference-in-difference estimator and estimate a set of multivariate logit models to quantify the effects of introducing Medicare IPPE coverage on the use of preventive services. Models are estimated separately for men and women. Data for the analysis come from the 1996-2008 Health and Retirement Study. Among both men and women, having coverage for a one-time IPPE under Medicare had no effects on the utilization of any of the preventive services listed above. In this study, we find that offering coverage for a one-time IPPE under Medicare was insufficient to spur greater use of preventive services among new Medicare beneficiaries. These findings are important and suggest that policy-makers may need to consider other approaches to increase the use of recommended preventive services.

RESUMO

OBJECTIVE: Examine differences in health care expenditures between foreign-born and U.S.-born adults in late mid-life, and how these differences change after age 65, when Medicare is near-universal. DATA: Medical Expenditures Panel Survey data (2000-2010) on adults ages 55-75 years (n = 46,132) to examine annual total and payer-specific expenditures. STUDY DESIGN: We use (1) propensity score matching to generate quasi-experimental samples with equivalent health needs and health care preferences, (2) generalized linear modeling to estimate group differences in expenditures, and (3) bootstrapping methods to obtain variance estimates for significance testing. PRINCIPAL FINDINGS: Among adults ages 55-64, the foreign-born spend $3,314 (p < .001) less on health care, even when they have equivalent health needs and health care preferences. This difference is due mainly to lower spending through private insurance. After age 65, differences in total spending disappear but not differences in payer-specific spending. The foreign-born continue to spend significantly less through private insurance and begin to spend significantly more through Medicare and Medicaid. CONCLUSION: Foreign-born adults in late mid-life spend significantly less on health care than U.S.-born adults. After age 65, with near-universal Medicare coverage, differences in total spending disappear between the groups, although differences in spending by payer persist.

RESUMO

OBJECTIVE: Beginning January 1st, 2011 in the United States the Affordable Care Act enhanced Medicare coverage for preventive services by eliminating patient cost-sharing under Part B and by introducing an "Annual Wellness Visit," also free-of-charge. We evaluated the early effects of these reforms on utilization of preventive services. METHOD: We analyzed nationally representative data on 15,044 Medicare seniors from the 2008-2010, and 2012 Medical Expenditure Panel Survey, and examined self-reported cholesterol test, blood pressure check, flu vaccination, endoscopy, fecal occult blood test, prostate specific antigen test, breast examination, and mammography. RESULTS: Enhanced Medicare benefits had no effects on preventive service utilization among Medicare seniors in 2012, including those with traditional Medicare and no other supplemental insurance, who stood to benefit the most from Part B enhancements. CONCLUSION: The muted overall response can be partly attributed to the fact that most seniors already held insurance that fully covered preventive services. While insurance enhancements can sometimes raise utilization, in the case of preventive services there are other fundamental barriers that require attention. Educating and incentivizing physicians about the need to refer/recommend screenings, and enhancing knowledge among seniors about the importance of preventive care are two steps that would likely go a long way towards increasing utilization.

RESUMO

OBJECTIVE: The aim of this study is to evaluate whether Medicare Part D reduced racial/ethnic disparities in hospital utilization among Medicare seniors, based on the Institute of Medicine's definition of a disparity. METHOD: Using data on 43,098 adult respondents to the 2002-2009 Medical Expenditure Panel Survey, we derive a difference-in-difference-in-differences estimator using a multivariate regression framework, and measure Part D's effects on disparities in any hospitalization, the number of nights hospitalized, and inpatient expenses. RESULTS: Part D narrowed racial/ethnic disparities in hospital utilization. For African Americans, it reduced the disparity in any hospitalization by 2.94% (p < .001) but had no effect on disparities in nights hospitalized or inpatient expenses. For Hispanics, Part D reduced disparities in nights hospitalized by 1.58 nights (p = .009) and in inpatient expenses by US$3,453 (p < .001). DISCUSSION: Following Medicare Part D, disparities in hospital utilization narrowed significantly for both African American and Hispanic seniors, but in different ways for each population.

RESUMO

Using 2008 physician survey data, we estimate the relationship between the generosity of fees paid to primary care physicians under Medicaid and Medicare and his/her willingness to accept new patients covered by Medicaid, Medicare, or both programs (i.e., dually enrolled patients). Findings reveal physicians are highly responsive to fee generosity under both programs. Also, their willingness to accept patients under either program is affected by the generosity of fees under the other program, i.e., there are significant spillover effects between Medicare and Medicare fee generosity. We also simulate how physicians in 2008 would have likely responded to Medicaid and Medicare payment reforms similar to those embodied in the 2010 Affordable Care Act, had they been permanently in place in 2008. Our findings suggest that "Medicaid Parity" for primary care physicians would have likely dramatically improved physician willingness to accept new Medicaid patients while only slightly reducing their willingness to accept new Medicare patients. Also, many more primary care physicians would have been willing to treat dually enrolled patients.

RESUMO

BACKGROUND: Medicare covers several cancer screening tests not currently recommended by the U.S. Preventive Services Task Force (Task Force). In September 2002, the Task Force relaxed the upper age limit of 70 years for breast cancer screening recommendations, and in March 2003 an upper age limit of 65 years was introduced for cervical cancer screening recommendations. We assessed whether mammogram and Pap test utilization among women with Medicare coverage is influenced by changes in the Task Force's recommendations for screening. METHODS: We identified female Medicare beneficiaries aged 66-80 years and used bivariate probit regression to examine the receipt of breast (mammogram) and cervical (Pap test) cancer screening reflecting changes in the Task Force recommendations. We analyzed 9,760 Medicare Current Beneficiary Survey responses from 2001 to 2007. RESULTS: More than two-thirds reported receiving a mammogram and more than one-third a Pap test in the previous 2 years. Lack of recommendation was given as a reason for not getting screened among the majority (51% for mammogram and 75% for Pap). After controlling for beneficiary-level socioeconomic characteristics and access to care factors, we did not observe a significant change in breast and cervical cancer screening patterns following the changes in Task Force recommendations. CONCLUSIONS: Although there is evidence that many Medicare beneficiaries adhere to screening guidelines, some women may be receiving non-recommended screening services covered by Medicare.

RESUMO

Medicare adjusts its payments to physicians for geographic differences in the cost of operating a medical practice, but the method it uses is imprecise. We measure the inaccuracy in its geographic adjustment factors and categorize beneficiaries by whether they live where Medicare's formula is favorable or unfavorable to physicians. Then, using the 2001-2003 Medicare Current Beneficiary Survey, we examine whether differences in physician payment generosity, that is, whether favorable or unfavorable, influence the satisfaction ratings Medicare seniors assign to their quality of care and access to services. We find strong evidence that they do. Many beneficiaries live in payment-unfavorable areas and receive a less satisfying quality of care and less satisfying access to services than beneficiaries who live where payments are favorable to physicians.

RESUMO

OBJECTIVE: To evaluate whether Medicare Part D has reduced racial/ethnic disparities in prescription drug utilization and spending. DATA: Nationally representative data on white, African American, and Hispanic Medicare seniors from the 2002-2009 Medical Expenditure Panel Survey are analyzed. Five measures are examined: filling any prescriptions during the year, the number of prescriptions filled, total annual prescription spending, annual out-of-pocket prescription spending, and average copay level. STUDY DESIGN: We apply the Institute of Medicine's definition of a racial/ethnic disparity and adopt a difference-in-difference-in-differences (DDD) estimator using a multivariate regression framework. The treatment group consists of Medicare seniors, the comparison group, adults without Medicare aged 55-63 years. PRINCIPAL FINDINGS: Difference-in-difference-in-differences estimates suggest that for African Americans Part D increased the disparity in annual spending on prescription drugs by $258 (p=.011), yet had no effect on other measures of prescription drug disparities. For Hispanics, DDD estimates suggest that the program reduced the disparities in annual number of prescriptions filled, annual total and out-of-pocket spending on prescription drugs by 2.9 (p=.077), $282 (p=.019) and $143 (p<.001), respectively. CONCLUSION: Medicare Part D had mixed effects. Although it reduced Hispanic/white disparities related to prescription drugs among seniors, it increased the African American/white disparity in total annual spending on prescription drugs.

RESUMO

BACKGROUND: On January 1, 2005, Medicare began covering a "Welcome to Medicare" visit (WMV) for new enrollees with fee-for-service (FFS) Medicare (Parts A and B). The new benefit was expected to increase demand for mammography and Pap tests among women transitioning onto Medicare. This study examined whether Medicare's coverage of a WMV influenced the use of mammography and Pap tests among women aged 65 and 66 years with FFS Medicare. METHODS: Medicare Current Beneficiary Survey (MCBS) data from 2001 to 2007 were linked with Medicare claims. Utilization rates for preventive visits, mammography, and Pap tests were measured among women entering Medicare. Multivariate logistic regressions were estimated to quantify the effects of the new Medicare benefit on the use of these screening tests, controlling for patient characteristics. RESULTS: Regression-adjusted mammography and Pap test rates did not increase after WMV coverage was introduced. The 2005 reform had nonsignificant trivial effects on the use of both tests, most likely because few of the women who were eligible for a WMV took advantage of it. CONCLUSIONS: Medicare coverage of a WMV had no impact on mammography screenings or Pap tests among women who were eligible for the benefit.

RESUMO

OBJECTIVES: To compare racial/ethnic disparities in access to physician services among older adults in 2000 and 2007 and to identify potential factors driving the changes observed. METHOD: Using 2000 and 2007 Medical Expenditure Panel Survey data, we examine 2 measures of access for adults aged 65 and older: whether the individual reports of having a usual source of care (USC) and whether he/she made any physician visits during the past year. We model the determinants of access using logistic regressions and then calculate disparities in access between older African Americans and older Whites and between older Hispanics and older Whites applying a disparity definition suggested by the Institute of Medicine. RESULTS: In both 2000 and 2007, significant racial/ethnic disparities were evident in having no USC and in having no physician visits. Over the period, the disparity in having no physician visits diminished by 6.16% (p = .003) for African Americans, but it worsened by 5.28% (p = .021) for Hispanics. These changes were associated with a positive shift in the distribution of education among older African Americans and an erosion in Medicare among Hispanic seniors. CONCLUSION: Among older adults, disparities in access to physician services have diminished for African Americans but have grown worse for Hispanics.
