Item A Comparison of Medicare Prospective Payment Systems on P.T.C.A. and Stent Outcomes in an Urban Hospital(2001-05-01) Compton, Ben H.; Doug A. Mains; P. E. HilsenrathCompton, Ben H., A Comparison of Medicare Prospective Systems on P.T.C.A. and STENT Outcomes in an Urban Hospital. Master of Public Health (Health Services Administration), May 2001, 57 pp., 10 tables, 1 graph, bibliography, 51 titles. To determine if differences in outcomes exist between Medicare prospective payment systems when doing percutaneous transluminal coronary angioplasty (PTCA) or STENT surgeries. From January 1999 and December 2000, 146 Medicare patients were identified with 35 being outpatient and 111 inpatient. A separate group of 1-day inpatients was used as a comparison for the outpatient group. Results from the comparison reveal that in the three groups, the majority of patients were white, non-Hispanic males who were about 70 years of age. The 1-day inpatient group had the highest profit of all three with about $3,000 while the inpatient group broke even. The outpatient group had no in-hospital deaths or complications while all three had equal amounts of comorbidities. The conclusion is that losses will probably occur if PTCA and STENTs are done outpatient. Possible solutions are moving to an inpatient setting or determining which costs can be reduced in the outpatient setting.Item A Machine Learning Approach to Identify Predictors of Potentially Inappropriate Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) Use in Older Adults with Osteoarthritis(MDPI, 2020-12-28) Patel, Jayeshkumar; Ladani, Amit; Sambamoorthi, Nethra; LeMasters, Traci; Dwibedi, Nilanjana; Sambamoorthi, UshaEvidence from some studies suggest that osteoarthritis (OA) patients are often prescribed non-steroidal anti-inflammatory drugs (NSAIDs) that are not in accordance with their cardiovascular (CV) or gastrointestinal (GI) risk profiles. However, no such study has been carried out in the United States. Therefore, we sought to examine the prevalence and predictors of potentially inappropriate NSAIDs use in older adults (age > 65) with OA using machine learning with real-world data from Optum De-identified Clinformatics((R)) Data Mart. We identified a retrospective cohort of eligible individuals using data from 2015 (baseline) and 2016 (follow-up). Potentially inappropriate NSAIDs use was identified using the type (COX-2 selective vs. non-selective) and length of NSAIDs use and an individual's CV and GI risk. Predictors of potentially inappropriate NSAIDs use were identified using eXtreme Gradient Boosting. Our study cohort comprised of 44,990 individuals (mean age 75.9 years). We found that 12.8% individuals had potentially inappropriate NSAIDs use, but the rate was disproportionately higher (44.5%) in individuals at low CV/high GI risk. Longer duration of NSAIDs use during baseline (AOR 1.02; 95% CI:1.02-1.02 for both non-selective and selective NSAIDs) was associated with a higher risk of potentially inappropriate NSAIDs use. Additionally, individuals with low CV/high GI (AOR 1.34; 95% CI:1.20-1.50) and high CV/low GI risk (AOR 1.61; 95% CI:1.34-1.93) were also more likely to have potentially inappropriate NSAIDs use. Heightened surveillance of older adults with OA requiring NSAIDs is warranted.Item A Study of Disparities in the Receipt of Anti-Retroviral Drugs, Health Status, and Insurance Coverage Among a Sample of HIV-Positive Adults(2006-12-01) Wittenmyer, Brian F.; Kristine Lykens; Jeffrey Talbert; Tim StrawdermanWittenmyer, Brian F., A Study of Disparities in the Receipt of Anti-Retroviral Drugs, Health Status, and Insurance Coverage among a Sample of HIV-Positive Adults. Master of Public Health (Health Management and Policy), December 2006, 88 pp., 8 tables, references, 32 titles. Anti-retroviral medications (ARV) are effective at treating HIV/AIDS. Medicare, Medicaid, and ADAP are public programs that supply ARVs to needy patients in the U.S. Studies have documented dispartities in AIDS incidence/prevalence, insurance, and ARV-use. The study described demographic, clinical, and insurance characteristics of a sample of HIV+ persons. The study explored relationships between AIDS diagnosis, health status, and ARV-receipt and demographic, insurance, and clinical variables. Disparities in ARV-receipt, AIDS diagnosis, and health-status were found for gender, age, race, geographic region, and SES. Policy recommendations included: shortening the disability waiting-period for Medicare-eligibility, and relaxing Medicaid’s income-eligibility requirements.Item Shorter length of hospital stay for hip fracture in those with dementia and without a known diagnosis of osteoporosis in the USA(BioMed Central Ltd., 2020-12-03) Rasu, Rafia S.; Zalmai, Rana; Karpes Matusevich, Aliza R.; Hunt, Suzanne L.; Phadnis, Milind A.; Rianon, NahidBACKGROUND: About 50% of all hospitalized fragility fracture cases in older Americans are hip fractures. Approximately 3/4 of fracture-related costs in the USA are attributable to hip fractures, and these are mostly covered by Medicare. Hip fracture patients with dementia, including Alzheimer's disease, have worse health outcomes including longer hospital length of stay (LOS) and charges. LOS and hospital charges for dementia patients are usually higher than for those without dementia. Research describing LOS and acute care charges for hip fractures has mostly focused on these outcomes in trauma patients without a known pre-admission diagnosis of osteoporosis (OP). Lack of documented diagnosis put patients at risk of not having an appropriate treatment plan for OP. Whether having a diagnosis of OP would have an effect on hospital outcomes in dementia patients has not been explored. We aim to investigate whether having a diagnosis of OP, dementia, or both has an effect on LOS and hospital charges. In addition, we also report prevalence of common comorbidities in the study population and their effects on hospital outcomes. METHODS: We conducted a cross-sectional analysis of claims data (2012-2013) for 2175 Medicare beneficiaries (>/=65 years) in the USA. RESULTS: Compared to those without OP or dementia, patients with demenia only had a shorter LOS (by 5%; P = .04). Median LOS was 6 days (interquartile range [IQR]: 5-7), and the median hospital charges were $45,100 (IQR: 31,500 - 65,600). In general, White patients had a shorter LOS (by 7%), and those with CHF and ischemic heart disease (IHD) had longer LOS (by 7 and 4%, respectively). Hospital charges were 6% lower for women, and 16% lower for White patients. CONCLUSION: This is the first study evaluating LOS in dementia in the context of hip fracture which also disagrees with previous reporting about longer LOS in dementia patients. Patients with CHF and IHD remains at high risk for longer LOS regardless of their diagnosis of dementia or OP.Item The Association Between Medical Insurance Coverage, In-Hospital Case Fatality Rate, and Length of Hospital Stay Following Admission for Acute Myocardial Infarction in Texas Hospitals(2002-07-01) Boppana, Dinesh; Antonio A. Rene; Sally Blakley; Doug A. MainsDinesh Boppana, The Association Between Medical Insurance Coverage, In-hospital Case Fatality Rate and Length of Hospital Stay Following Admission for Acute Myocardial Infarction in Texas Hospitals. Master of Public Health, July 2002, 53pp., 22 tables, bibliography, 63 titles. This study reports the possible association between type of medical insurance coverage, in-hospital case fatality rates and length of hospital stay following admission for acute myocardial infarction (AMI) in Texas hospitals for the year of 1999. Methods. The data sources was the Texas Health Care Information Council public use data file. Crude and multivariable-adjusted analyses were used to examine the relation between type of medical insurance coverage, length of hospital stay and in-hospital case-fatality rates following AMI. Results. Relative to the referent group of private or commercial insurance patients (odds ratio, 1.0) the multi-variable adjusted odds for dying during acute hospitalization were 1.98 (95% CI, 1.53-2.52) for Medicaid, 1.45 (95% CI, 1.27-1.64) for Medicare. The mean length of hospital stay in days after excluding patients with a prolonged hospitalization was 8.53 (95% CI, 7.93-9.14) for Medicaid, 6.75 (95% CI, 6.52-6.95) for Medicare, and 5.58 (95% CI, 5.37-5.79) for commercial insurance. Conclusions. The findings suggest that patient enrolled in Medicaid and Medicare insurance program had increased in-hospital mortality, and higher length of hospital stay following admission with AMI when compared to the patients enrolled in commercial insurance.
