Gaps In Quality Of Care Not Consistent Between Traditional Medicare, Medicare Advantage For Racial And Ethnic Groups.

The quality of care experienced by members of racial and ethnic minority groups in Medicare Advantage, which is an increasingly important source of Medicare coverage for these groups, has critical implications for health equity. Comparing gaps in Medicare Advantage and traditional Medicare for three quality-of-care outcomes, measured by adverse health events, between minority and non-Hispanic White populations, we found that the relative magnitude of the gaps varied both by racial and ethnic minority group and by quality measure. Hispanic versus non-Hispanic White gaps were smaller in Medicare Advantage than in traditional Medicare for all outcomes: avoidable emergency department use, preventable hospitalizations, and thirty-day hospital readmissions. The gap between non-Hispanic Black and non-Hispanic White populations was larger in Medicare Advantage than in traditional Medicare for avoidable emergency department use but was no different for hospital readmissions and was smaller for preventable hospitalizations. The Asian versus non-Hispanic White gap was similar in Medicare Advantage and traditional Medicare for avoidable emergency department use and preventable hospitalizations but was larger in Medicare Advantage for hospital readmissions. As Medicare Advantage enrollment expands, monitoring the quality of care for enrollees who are members of racial and ethnic minority groups will remain important.

Differential impacts of reduced worktime on work-life balance in Korea.

This study analyzes the heterogenous effects of reducing weekly work hour on workers' quality of life in Korea. Using longitudinal household data from the Korean Labor and Income Panel Study (KLIPS) from 2001 to 2017, this study aims to shed light on how the work hour reduction policy may differently affect workers with different levels of resources and support by demographic and socioeconomic status. Our estimates from the difference-in-differences approach exploiting the staggered implementation of the work hour reduction policy indicate that the policy increased leisure satisfaction of female workers with low educational level and female workers in regular or inflexible work setting. Given Korea's exceedingly long working hours and inequities in the labor market, a better understanding of the complex factors that affect work-life balance can be helpful in developing policies supportive of healthy work-life balance for workers. This study, to our knowledge, is the first to investigate the composition of workers in the Korean labor market and examine differential impacts of the workhour reduction policy by demographic and socioeconomic status.

The effectiveness of financial incentives for COVID-19 vaccination: A systematic review.

Financial incentives are a controversial strategy for increasing vaccination. In this systematic review, we evaluated: 1) the effects of incentives on COVID-19 vaccinations; 2) whether effects differed based on study outcome, study design, incentive type and timing, or sample sociodemographic characteristics; and 3) the cost of incentives per additional vaccine administered. We searched PubMed, EMBASE, Scopus, and Econlit up to March 2022 for terms related to COVID, vaccines, and financial incentives, and identified 38 peer-reviewed, quantitative studies. Independent raters extracted study data and evaluated study quality. Studies examined the impact of financial incentives on COVID-19 vaccine uptake (k = 18), related psychological outcomes (e.g., vaccine intentions, k = 19), or both types of outcomes. For studies of vaccine uptake, none found that financial incentives had a negative effect on uptake, and most rigorous studies found that incentives had a positive effect on uptake. By contrast, studies of vaccine intentions were inconclusive. While three studies concluded that incentives may negatively impact vaccine intentions for some individuals, they had methodological limitations. Study outcomes (uptake versus intentions) and study design (experimental versus observational frameworks) appeared to influence results more than incentive type or timing. Additionally, income and political affiliation may moderate responses to incentives. Most studies evaluating cost per additional vaccine administered found that they ranged from $49-75. Overall, fears about financial incentives decreasing COVID-19 vaccine uptake are not supported by the evidence. Financial incentives likely increase COVID-19 vaccine uptake. While these increases appear to be small, they may be meaningful across populations.

The impact of benefits coverage expansion of social health insurance: Evidence from Korea.

Despite mandatory social health insurance in Korea, the fraction of total healthcare spending paid out-of-pocket has been considerably high. In 2013, the Korean government expanded benefits coverage of social insurance for patients diagnosed with the costliest disease groups (cardiovascular and cerebrovascular diseases, cancer, and intractable diseases). We analyze individual longitudinal information from the 2010 to 2016 Korea Health Panel to estimate the impact of the policy change on healthcare spending, utilization, and enrollment in private supplemental health insurance. Impacts on other health-related and financial measures are additionally assessed to evaluate the effects in multiple dimensions. Our difference-in-differences approach with entropy balancing weights shows that the expansion of benefits coverage of public health insurance reduced out-of-pocket spending on health by 30% without accompanying increases in healthcare utilization. The impact was smaller for the individuals with high socioeconomic characteristics, who are more likely to use other costly services that remained unaffected by the policy. We do not find evidence that expanding social insurance benefits coverage changed the demand for supplemental private health insurance.

Robotic Prostatectomy and Prostate Cancer-Related Medicaid Spending: Evidence from New York State.

BACKGROUND: Robotic prostatectomy is a costly new technology, but the costs may be offset by changes in treatment patterns. The net effect of this technology on Medicaid spending has not been assessed. OBJECTIVE: To identify the association of the local availability of robotic surgical technology with choice of initial treatment for prostate cancer and total prostate cancer-related treatment costs. DESIGN AND PARTICIPANTS: This cohort study used New York State Medicaid data to examine the experience of 9564 Medicaid beneficiaries 40-64 years old who received a prostate biopsy between 2008 and 2017 and were diagnosed with prostate cancer. The local availability of robotic surgical technology was measured as distance from zip code centroids of patient's residence to the nearest hospital with a robot and the annual number of robotic prostatectomies performed in the Hospital Referral Region. MAIN MEASURES: Multivariate linear models were used to relate regional access to robots to the choice of initial therapy and prostate cancer treatment costs during the year after diagnosis. KEY RESULTS: The mean age of the sample of 9564 men was 58 years; 30% of the sample were White, 26% were Black, and 22% were Hispanic. Doubling the distance to the nearest hospital with a robot was associated with a reduction in robotic surgery rates of 3.7 percentage points and an increase in the rate of use of radiation therapy of 5.2 percentage points. Increasing the annual number of robotic surgeries performed in a region by 10 was associated with a decrease in the probability of undergoing radiation therapy of 0.6 percentage point and a $434 reduction in total prostate cancer-related costs per Medicaid patient. CONCLUSIONS: A full accounting of the costs of a new technology will depend on when it is used and the payment rate for its use relative to payment rates for substitutes.

Associations Between a New York City Paid Sick Leave Mandate and Health Care Utilization Among Medicaid Beneficiaries in New York City and New York State.

Importance: More evidence on associations between mandated paid sick leave and health service utilization among low-income adults is needed to guide health policy and legislation nationwide. Objective: To evaluate the association between New York City's 2014 paid sick leave mandate and health care utilization among Medicaid-enrolled adults. Design Setting and Participants: This retrospective cohort study used New York State Medicaid administrative data for adults 18 to 64 years old continuously enrolled in Medicaid from August 1, 2011, through July 31, 2017. A difference-in-differences approach with entropy balancing weights was used to compare New York City with the rest of New York State to assess the association of the paid sick leave mandate with health care utilization, and for those 40 to 64 years old, with preventive care utilization. The data analysis was performed from June through August 2020. Exposures: Temporal and spatial variation in exposure to the mandate. Main Outcomes and Measures: Annual health care utilization (emergency care, specialist visits, and primary care clinician visits) per Medicaid-enrolled adult. Secondary outcomes include categories of emergency utilization and utilization of 5 preventive services. Results: Of 552 857 individuals (mean [SD] age, 43 [12] years; 351 130 [64%] women) who met inclusion criteria, 99 181 (18%) were White, 162 492 (29%) Black, and 138 061 (25%) Hispanic. Paid sick leave was significantly associated with a reduction in the probability of emergency care (-0.6 percentage points [pp]; 95% CI, -0.7 to -0.5 pp; P < .001), including a 0.3 pp reduction (95% CI, -0.4 to -0.2; P < .001) in care for conditions treatable in a primary care setting and an increase in annual outpatient visits (0.124 pp; 95% CI, 0.040 to 0.208 pp; P < .001). Among those 40 to 64 years old, the mandate was significantly associated with increased probabilities of glycated hemoglobin A1c level testing (2.9 pp; 95% CI, 2.5-3.3 pp; P < .001), blood cholesterol testing (2.7 pp; 95% CI, 2.5-2.9 pp; P < .001), and colon cancer screening (0.4 pp; 95% CI, 0.2-0.6 pp; P < .001). Conclusions and Relevance: This retrospective cohort study of nonelderly adults enrolled in Medicaid New York State showed that mandated paid sick leave in New York City was significantly associated with differences in several dimensions of health care services use.

Behavioral responses to the 2015 MERS epidemic in Korea.

Understanding behavioral responses to epidemics is important in evaluating the broad health consequences of emerging infectious diseases. Building on the economic epidemiology literature, this study investigates individual behavioral responses to the 2015 Middle East Respiratory Syndrome Coronavirus (MERS-CoV) epidemic in Korea using a panel of individuals in a nationally representative survey. Results show that exposure to the epidemic led to lasting impacts on smoking and drinking behaviors, indicating that emerging infectious disease outbreaks are motivations for behavioral changes and opportunities for public policy interventions. In particular, individuals in the hardest-hit regions or socially connected persons were more likely to change their risky behaviors, suggesting that intensity of exposure and social interactions are potential mechanisms.

Moral hazard effects of supplemental private health insurance in Korea.

Supplemental private health insurance has gained popularity despite having a mandatory social health insurance program in Korea. Private insurance supplements the social insurance program by covering co-pays and services not covered by social insurance. Using longitudinal microdata from the 2008-2014 Korea Health Panel, this study finds evidence of favorable selection into supplemental private insurance. Results show that supplemental private insurance increases outpatient and hospitalization utilization. Private health insurance generates welfare benefits especially among the elderly and low-income individuals, though the coverage rate for these groups is low.

Impacts of expanding provider choice for free flu vaccination among the elderly in Korea.

The Korean government, to increase the vaccination rates, implemented the policy expanding provider choice for free seasonal influenza vaccine for the elderly through contracting the provision of immunization to the private sector in 2015. Using the annual nationally representative individual between 2014-2017, this study explores the impacts of the policy change by using a difference-in-differences approach. Results show that influenza vaccine uptake at private clinics increases by 12 percentage points after the policy change. However, this effect is offset by a reduction in uptake at public health centers by 13 percentage points. As a result, we find no evidence that the policy increases overall vaccination coverage among the elderly. These results indicate that policymakers need to explore the reasons for vaccine hesitancy before delivering interventions.

The effect of outdoor smoking ban: Evidence from Korea.

To address exposure to secondhand smoke, which is highly prevalent in Korea, local governments have implemented smoking bans at open public places (parks, bus stops, and school zones) since 2011. Exploiting temporal and spatial variation in the implementation dates of these bans, this study estimates their causal effects on individual smoking behavior. The individual-level longitudinal data from the 2009-2017 Korean Labor and Income Panel Study are linked to the smoking ban legislation information from the National Law Information Center. I find robust evidence that outdoor smoking bans increased the probability of making a quit attempt by 16%. This effect appears immediately after a ban goes into effect and lasts for three or more years. People who spend more time outdoors are more likely to change smoking behavior. I also find heterogeneity in effects across the amount of monetary penalty. Whereas the policy change did not affect the prevalence of smoking overall, higher penalties had stronger impacts on reducing the intensity of smoking and increasing the propensity to try to quit.

Offset Effects of Outpatient Cost-sharing for the Poor in Korea.

OBJECTIVE: The objective of this study was to evaluate the impacts of the implementation of patient cost-sharing for an outpatient visit and prescription drugs for poor and nonable bodied Koreans in 2007. DATA SOURCES/STUDY SETTINGS: Nationally-representative longitudinal data sets (Korea Welfare Panel Study and the Korean Longitudinal Study of Ageing) in 2006, 2008, and 2010. RESEARCH DESIGN: Propensity score matching with difference-in-differences framework exploiting within-person variation in cost-sharing. RESULTS: Decreases in the probability of outpatient visit are offset by increases in the likelihood of hospitalization after the policy change. Cost-sharing also decreases drug adherence by 20%, particularly among chronically-ill persons. CONCLUSION: Because the costs of increased hospitalization among Medical Aid enrollees accrue to the government, the introduction of outpatient cost-sharing does not achieve the goal of cost control.

Intergenerational effects of old-age pension on children's health and well-being.

This study estimates the impacts of the basic old-age pension reform in South Korea on childhood/adolescent health and well-being. Facing a rapidly aging population and the increasing demand for social security for the elderly, the government introduced the basic pension program in 2007, which covered 70% of citizens 65 years or older. Information is obtained from a nationally representative panel of school-aged children from 2006 to 2012. A difference-in-differences approach exploiting within-person variation in exposure to the old-age pension program is used. The unconditional cash transfers for the elderly have substantial impacts on the health of grandchildren. In particular, there is gender-specific differential impacts. While grandmothers' pensions have positive impacts on granddaughters' heights and drinking participation, grandfathers' pension incomes lower smoking participation of grandsons. Results suggest that grandmothers and grandfathers put their resources for their grandchildren in a different way. It also indicates that household is not a unitary entity.

Social capital as a key determinant of willingness to join community-based health insurance: a household survey in Nepal.

OBJECTIVES: Although community-based health insurance (CBHI) schemes have been considered as an intermediate stage to achieve universal health coverage (UHC) in low-resource settings, there is a knowledge gap on ways to make it better. STUDY DESIGN: More than 4000 Nepalese households were randomly selected and surveyed. METHODS: Logistic and multivariate multinomial regressions were estimated. RESULTS: Overall, 88% of included household heads were willing to join CBHI, 61% were willing to pay annual premium less than 600 Nepalese rupees (US$5.6) per household, and more than a half (53%) responded that the government should subsidize a significant portion of the premium. Results showed that a higher level of social capital was significantly related with an increase in odds of accepting higher premiums, while individuals' health status and age did not have such associations. Individuals with bonding social capital were more likely to be inclined to join CBHI. Persons who said they can lend money for a living expense (bonding capital) did not want the government to subsidize the scheme, while this negative association would be reversed if persons had both bonding and bridging social capitals. CONCLUSION: We found significantly positive relationships between social capital and willingness to join and willingness to pay for CBHI in Nepal. Policymakers, aiming to achieve UHC, should be advised that bonding and bridging social capital have differing relationships with willingness to cooperate the external funding sources.

Unmet healthcare needs and health status: Panel evidence from Korea.

AIMS: Even though basic healthcare services have been considered human rights, studies on optimal level of healthcare utilization have produced mixed results. A growing body of literatures has been using unmet healthcare needs, a subjective survey measure, to find inequity in healthcare. But no studies so far have tried to reveal the association of unmet needs with health outcomes so it was hard to get the public's attention. To answer it, this study tries to reveal the associations between unmet healthcare needs and health outcomes. METHODS: A 4-year Korean panel dataset of 7,717 persons (31,668 person-years) were analyzed. Unmet healthcare needs were asked (if yes, its reason was also surveyed) if the respondent ever felt healthcare services were needed but could not receive it in the past 12 months. A health-related quality of life instrument (EQ-5D) and self-rated health were used as dependent variables. To avoid simultaneity, 1-year lagged outcome variables were used. And to control for unobserved individual heterogeneity, fixed effects estimation was also run based on Grossman's human capital model. FINDINGS: Since 2009, more than 14.5% of the study population had reported unmet healthcare needs. When 1-year lagged health outcome variables were regressed on unmet needs, compared to the means, unmet needs were found to associate with 1% decline in EQ-5D and 4.5% decline in self-rated health. Unmet needs due to mild symptoms were not related with outcomes in fixed effects estimation among the elderly. CONCLUSIONS: Even though causal inference were not found, the association between unmet needs and health outcomes were established. Recognizing demand side determinants of healthcare was a strength of this study.

Association between local government social expenditures and mortality levels in Korea.

OBJECTIVES: We examined the association between social expenditures of the local government and the mortality level in Korea, 2004 to 2010. METHODS: We used social expenditure data of 230 local governments during 2004 to 2010 from the Social Expenditure Database prepared by the Korean Institute for Health and Social Affairs. Fixed effect panel data regression analysis was adopted to look for associations between social expenditures and age-standardized mortality and the premature death index. RESULTS: Social expenditures of local governments per capita was not significantly associated with standardized mortality but was associated with the premature death index (decline of 1.0 [for males] and 0.5 [for females] for each expenditure of 100 000 Korean won, i.e., approximately 100 US dollar). As an index of the voluntary effort of local governments, the self-managed project ratio was associated with a decline in the standardized mortality in females (decline of 0.4 for each increase of 1%). The share of health care was not significant. CONCLUSIONS: There were associations between social expenditures of the local government and the mortality level in Korea. In particular, social expenditures per capita were significantly associated with a decline in premature death. However, the voluntary efforts of local governments were not significantly related to the decline in premature death.

Social determinants of smoking behavior: the Healthy Twin Study, Korea.

OBJECTIVES: The purpose of this study was to identify any influence of socioeconomic status on smoking and smoking cessation in a situation where genetic factors are controlled. METHODS: The sample for this study was 2502 members of the twins and families cohort who participated in the Korean Healthy Twins Study from 2005 to 2009. Groups of brothers or sisters, including twins and fraternal twins, were compared in terms of smoking and smoking cessation behaviors according to differences in socioeconomic status and gender. RESULTS: In a situation with complete control of genetic factors, results showed that the daily smoking amount, cumulative smoking amount, and dependence on nicotine decreased with higher-status occupations, and the rate of smoking and amount of cumulative smoking decreased with higher levels of education. Regarding smoking cessation behavior, a higher level of education was associated with a lower smoking cessation rate, and no significant gender differences were found. CONCLUSIONS: Environmental factors had a stronger influence on smoking behavior than did genetic factors. Genetic factors had greater influence on smoking cessation than did environmental factors; however, this requires verification in further studies.
