<p>The dissertation is consisted of two essays on Affordable Care Act Marketplace plan pricing. These two essays are the two chapters of the dissertation respectively.  </p> <p>First essay studies the effect of Medicaid expansion on ACA Marketplace plan premium. The Affordable Care Act (ACA) aims to mitigate Americans’ uninsured crisis by expanding Medicaid and establishing the ACA Marketplace. The Medicaid expansion has a profound impact on Marketplace plan premiums. On the one hand, it lowers the premiums because the expansion drives out the people with lower income from Marketplace plans, resulting in a pool with a lower risk score for these plans. On the other hand, the Medicaid expansion may shrink the pool size of Marketplace plans, resulting in a riskier pool and a higher Marketplace plan premium. Integrating data from multiple sources, we study how these two competing effects vary across markets with different demographics. We find that the premium-reduction effect is less pronounced in more wealthy markets, while the premium-increase effect is less pronounced in more populous markets. We further find that the Medicaid expansion overall decreased the Marketplace premiums, with more reduction for Silver plans than Bronze plans. We also explore how the Medicaid expansion can lower Marketplace premiums indirectly through the change of the market structure. We finally show the heterogeneity of the net impact of the Medicaid expansion on Marketplace premiums across markets. Our results offer important policy and managerial implications.</p> <p>The second essay explores the effect of insurer competition on marketplace plan premiums. ACA Marketplace is a new market opportunity for insurers that grant them access to a new group of customers who were not insured before. Previous studies utilize ACA marketplace data and find that additional insurers on the market are associated with a premium decrease in Marketplaces for a benchmark plan. However, the impact of the insurer entry on the premium is not the same for all plans. Using data from 2014 to 2017, we empirically examine the effect of insurer entry on the premium on Marketplace. Our study first confirms the finding that the premium of the second-lowest Silver plans decreases in the number of insurers. We further find evidence of different price trends across plans of different quality levels with additional insurers on the market. When more insurers are on the market, the premium increases for higher-end plans and decreases for lower-end plans. Our analysis shows that intensified competition may exaggerate price discrimination in certain segments while alleviate price discrimination in other markets. The results offer important managerial implications. </p>

Healthcare fraud is a major problem within the healthcare industry. The study examined medical fraud, its laws, and punishments on federal and state levels. It compared medical fraud to non-fraud crimes done in the healthcare industry. This comparison will be done on a state level. The study attempted to analyze the severity of fraud against non-fraud and that doctors would commit fraud offenses more often than non-fraud offenses.

基於生存權的保障，國家應提供人民生活扶助與醫療救助等給付。全民健保施行後，大法官釋字四七二號揭示對於無力繳納保費者，國家應予適當救助，不得逕行拒絕給付。遂開啟一連串對經濟弱勢者的保費協助措施，輔以相關醫療補助辦法的補助。惟我國領有醫療補助的人口比例甚低。 以美國醫療救助為例，自一九六五年建立Medicaid制度後，發展自今已有超過百分之十五的人口領有醫療救助，其制度強調實質醫療需求的內涵。在美國採開放式醫療市場的情況下，Medicaid對於貧者所提供的醫療服務更形重要。 相對於我國縣（市）醫療補助辦法對於社會救助法規定之過度限縮，是否有違母法，深值檢討。此外，我國亦應放寬對收入戶的認定，並修正醫療補助的資格與內容，以提供更多實質醫療需求者的醫療保障。

The "work first" philosophy of the Personal Responsibility and Work Opportunity Reconciliation Act sent millions of people into the labor force, many for the first time. The result was a dramatic increase in the number of workers whose earnings failed to pull them and their families out of poverty. Assistance in the form of childcare, transportation, medical coverage, and the Earned Income Tax Credit is beginning to receive attention as support mechanisms for people who do not earn adequate wages and receive little benefits from their employers. This study examines the effectiveness of Georgia's approach to providing work support programs to its working poor citizens. No single entity is responsible for making work supports accessible. Thus, services often go underutilized because those who might qualify are not aware of their potential eligibility. Further, there is no state level strategy for ensuring that wage advancement is considered by agencies providing work support services. Using client administrative wage data from the Georgia Department of Labor and qualitative interviews from program staff, the state's structure for assisting the working poor is examined.

PURPOSE: Substantial research demonstrates that many nursing homes are not providing adequate quality of care for residents because of inadequate processes of care and insufficient numbers and training of nursing staff. Some residents experience poor-quality outcomes, such as pressure ulcers and unintended weight loss. To address these issues, the long-term care industry has focused on improving quality of care by improving staff education about care processes and reducing nurse turnover rate. The aim of this study was to compare the association between - licensed nurse hours of care and turnover rate to five quality measures—incidence of ADL decline, physical restraints, prevalence of pressure ulcers among residents with risk factors for skin breakdown, and prevalence of unintended weight loss. DESIGN: The study population included 618 freestanding Texas nursing facilities. A cross-sectional multiple regression analysis was conducted using 2007 data to examine the relationship between nurse staffing levels and turnover and resident outcomes with control variables for facility and resident characteristics. RESULTS: The high-risk pressure ulcer variable accounted for 10% of the variation in the regression model. LVN (hprd) was positively associated with an increase in high-risk pressure ulcers. The ADL decline variable accounted for 7.5% of the variation in the regression model, and RN hprd was positively associated with ADL decline. The prevalence of weight loss variable accounted for 3% of the variation in the regression model. RN turnover rate was approaching significance. The physical restraint variable accounted for 2% of the variation in the regression model. LVN contract hprd was significant and positively associated with an increase in physical restraint use although a minimal contribution to the model given the low percentage of LVN contract hprd. The prevalence of low-risk pressure ulcers was not significant. The control variable case mix index was positively associated with ADL decline, high-risk pressure ulcers, and weight loss. CONCLUSIONS: This research will contribute to understanding the relationship of licensed nursing staff to resident outcomes. Additionally, it will contribute to nursing education, research, and policy. While controlling for acuity using case mix index, some negative findings were still noted that requires further research. / text

Both diabetes and behavioral health disorders (mental and substance use disorders) are significant health issues in the United States. While previous studies have shown worse health outcomes in people with diabetes and co-occurring behavioral health disorders (BHDs) than those with diabetes alone, it is unclear whether the quality of diabetes care was poorer in the presence of co-occurring BHDs. Although previous research has observed a trend of positive outcomes in people with comprehensive diabetes care, there is a lack of evidence about whether that mode of care delivery can improve outcomes in people with co-occurring BHDs. Therefore, further studies are necessary. Using a combined dataset from Medicare and Medicaid claims for Massachusetts residents, this study compared the quality of diabetes care (e.g., having at least 1 hemoglobin A1c test) and diabetes outcomes (e.g., eye complications) among Medicare and Medicaid beneficiaries with diabetes and co-occurring BHDs to those with diabetes alone in Massachusetts in 2005. The results showed a mixed picture on the relationships between BHDs and diabetes outcomes. While substance use disorders had adverse impact on adherence to quality measures (e.g., 20% less likely to attain full adherence, p0.05). Findings from this dissertation research suggest that disparities exist in the quality of diabetes care and health outcomes between people with substance use disorders and those without. The mode of care delivery needs to be further examined so that interventions can be designed to improve the outcomes of people with diabetes.

Background: One in ten people in the U.S. are affected by a substance use disorder (SUD), roughly one third of whom are women. Rates of unintended pregnancy are higher in this population than in the general public. Little is understood about how women with SUD use prescription contraception and think about pregnancy. Methods: By analyzing Medicaid claims data and conducting qualitative interviews with women with SUD, this doctoral thesis seeks to: 1) compare any use of and consistent, continued coverage by prescription contraceptives between women with and without SUD; 2) determine the extent to which SUD is associated with pregnancy, abortion, and adverse feto-maternal outcomes in women who use prescription contraception; and 3) explore facilitators of and barriers to contraceptive utilization by women with SUD, using qualitative interviews. Results: Compared to women without SUD, women with SUD are less likely to use any prescription contraceptive, particularly long-acting reversible methods. Among women who do use long-acting methods, SUD is associated with less continued, consistent coverage by a prescription contraceptive. Among women who use contraception, SUD is also associated with increased odds of abortion. When interviewed, women with SUD report fatalistic attitudes towards pregnancy planning, and have difficulty conceptualizing how susceptibility to pregnancy may change over time. Women with SUD also report that pregnancy has substantial impact on their drug treatment prospects. Conclusions: This study is the first to examine contraceptive utilization by women with SUD who are enrolled in Medicaid or state-subsidized insurance. Our study may help to inform clinical practice and policy development to improve the reproductive health and wellbeing of women with SUD.
