Class of 2007 Abstract / Objectives: To investigate the relationship of price and prevalence of statins when new mediations enter the market and when old medications are withdrawn from the market. Methods: Patients that received a statin were enrolled in the Medicare Current Beneficiary Survey (MCBS) from 1992 to 2002. The overall prevalence of each statin as well as the prevalence of each statin for a patient’s drug coverage (no coverage, Medicaid, Medigap, employer coverage, or other public coverage) were analyzed. Results: The overall prevalence of statin was statistically significant for 1992 versus 2002 (p<0.001). When atorvastatin came to the market towards the end of 1996, there was no difference between simvastatin (p=0.24) and pravastatin (p=0.12) in 1997 versus 1998. Conclusions: There was a difference in the prevalence of statins when atorvastatin entered the market. When cerivastatin left the market, there was a difference in the prevalence of statin use. Atorvastatin became the most prevalent statin by the end of 2002. The price of statins appeared to decrease over time from $39.01 in 1992 to $31.95 in 2002. Also, the year atorvastatin was released the average price of statins increased to $36.57 in 1997.

The population of people ages 65 and older has increased since the 1960s and current estimates indicate it will double by 2060. Medicare is a federal health insurance program for people 65 or older in the United States. Medicare claims fraud and abuse is an ongoing issue that wastes a large amount of money every year resulting in higher health care costs and taxes for everyone. In this study, an empirical evaluation of several unsupervised machine learning approaches is performed which indicates reasonable fraud detection results. We employ two unsupervised machine learning algorithms, Isolation Forest and Unsupervised Random Forest, which have not been previously used for the detection of fraud and abuse on Medicare data. Additionally, we implement three other machine learning methods previously applied on Medicare data which include: Local Outlier Factor, Autoencoder, and k-Nearest Neighbor. For our dataset, we combine the 2012 to 2015 Medicare provider utilization and payment data and add fraud labels from the List of Excluded Individuals/Entities (LEIE) database. Results show that Local Outlier Factor is the best model to use for Medicare fraud detection. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2018. / FAU Electronic Theses and Dissertations Collection

The State Hospital and Medical League was a broadly based organization founded in 1936 and dedicated to achieving State Medicine, a fully funded holistic preventative and curative system, for Saskatchewan. Its study allows us to fill in gaps in what has been a primarily policy level historiography of Canadian medicare. Using Ian McKay's reconnaissance model, we also look at it as a locus for challenges to the entrenched, liberal and individualistic political social and professional hegemony.

Background-Heart failure (HF) is the leading cause for hospital readmission. Hospice care may help palliate HF symptoms but its association with 30-day all-cause readmission remains unknown. Methods and Results-Of the 8032 Medicare beneficiaries hospitalized for HF in 106 Alabama hospitals (1998-2001), 182 (2%) received discharge hospice referrals. Of the 7850 patients not receiving hospice referrals, 1608 (20%) died within 6 months post discharge (the hospice-eligible group). Propensity scores for hospice referral were estimated for each of the 1790 (182+1608) patients and were used to match 179 hospice-referral patients with 179 hospice-eligible patients who were balanced on 28 baseline characteristics (mean age, 79 years; 58% women; 18% non-white). Overall, 22% (1742/8032) died in 6 months, of whom 8% (134/1742) received hospice referrals. Among the 358 matched patients, 30-day all-cause readmission occurred in 5% and 41% of hospice-referral and hospice-eligible patients, respectively (hazard ratio associated with hospice referral, 0.12; 95% confidence interval, 0.06-0.24). Hazard ratios (95% confidence intervals) for 30-day all-cause readmission associated with hospice referral among the 126 patients who died and 232 patients who survived 30-day post discharge were 0.03 (0.04-0.21) and 0.17 (0.08-0.36), respectively. Although 30-day mortality was higher in the hospice referral group (43% versus 27%), it was similar at 90 days (64% versus 67% among hospice-eligible patients). Conclusions-A discharge hospice referral was associated with lower 30-day all-cause readmission among hospitalized patients with HF. However, most patients with HF who died within 6 months of hospital discharge did not receive a discharge hospice referral.

The objective of this DNP project was to highlight the significant impact of health promotion in older adults. As of January 2011, Medicare covers an Annual Wellness Visit (AWV), which is a result of the Affordable Care Act. The AWV allows patients the benefit of receiving covered wellness and preventive care services. Through surveys this project explored what healthcare providers and patients know about the Medicare AWV and what barriers and/or challenges they have experienced with the AWV. The responses to the surveys revealed that providers have misconceptions about the Medicare AWV and some of the patients did not know that Medicare part B offers a covered annual wellness visit. There were several barriers identified by both patients and providers and these barriers will be discussed and explored in this paper.

The purpose of the study is to determine what effect medicare has had on the distribution of public health care expenditures in the state of Oklahoma. The study tests that there is a significant correlation between medical vendor payments and indigency in Oklahoma or in other words that pre-medicare public health care dollars in Oklahoma were distributed to indigents.
