Measurement Matters: Changing Penalty Calculations Under The Hospital Acquired Condition Reduction Program (Hacrp) Cost Hospitals Millions, Olga A. Vsevolozhskaya, Karina C. Manz, Pierre M. Zephyr, Teresa M. Waters

Biostatistics Faculty Publications

BACKGROUND: Since October 2014, the Centers for Medicare and Medicaid Services has penalized 25% of U.S. hospitals with the highest rates of hospital-acquired conditions under the Hospital Acquired Conditions Reduction Program (HACRP). While early evaluations of the HACRP program reported cumulative reductions in hospital-acquired conditions, more recent studies have not found a clear association between receipt of the HACRP penalty and hospital quality of care. We posit that some of this disconnect may be driven by frequent scoring updates. The sensitivity of the HACRP penalties to updates in the program's scoring methodology has not been independently evaluated.

METHODS: We used …

An Egocentric Network Contact Tracing Experiment: Testing Different Procedures To Elicit Contacts And Places, Andrew Pilny, C. Joseph Huber

Communication Faculty Publications

Contact tracing is one of the oldest social network health interventions used to reduce the diffusion of various infectious diseases. However, some infectious diseases like COVID-19 amass at such a great scope that traditional methods of conducting contact tracing (e.g., face-to-face interviews) remain difficult to implement, pointing to the need to develop reliable and valid survey approaches. The purpose of this research is to test the effectiveness of three different egocentric survey methods for extracting contact tracing data: (1) a baseline approach, (2) a retrieval cue approach, and (3) a context-based approach. A sample of 397 college students were randomized …

Appalachian Caregiver Perspectives On Childhood Gun Safety In The Home, Dannell Boatman

Journal of Appalachian Health

Background: Childhood gun injuries pose a critical public health challenge. For children, unintentional gun injury deaths primarily occur in the home where parents or other adult guardians, referred to as caregivers hereafter, are responsible for safety. While the American Academic of Pediatrics recommends not having guns in areas where children live and play, firearms are often viewed as normative and fill an important role in many homes. This is particularly true in more rural areas, such as Appalachia, where there is a high density of gun ownership. Additional research is needed to understand rural caregivers’ current gun safety practices in …

Murray, Geert Jan Biessels, Claire Troakes, Henrik Zetterberg, John Hardy, Tammaryn Lashley, Alzheimer’S Disease Exome Sequencing Group, Florin Despa

Pharmacology and Nutritional Sciences Faculty Publications

Introduction

This study assessed the hypothesis that circulating human amylin (amyloid‐forming) cross‐seeds with amyloid beta (Aβ) in early Alzheimer's disease (AD).

Methods

Evidence of amylin‐AD pathology interaction was tested in brains of 31 familial AD mutation carriers and 20 cognitively unaffected individuals, in cerebrospinal fluid (CSF) (98 diseased and 117 control samples) and in genetic databases. For functional testing, we genetically manipulated amylin secretion in APP/PS1 and non‐APP/PS1 rats.

Results

Amylin‐Aβ cross‐seeding was identified in AD brains. High CSF amylin levels were associated with decreased CSF Aβ42 concentrations. AD risk and amylin gene are not correlated. Suppressed amylin secretion protected …

Memory-Related Frontal Brainwaves Predict Transition To Mild Cognitive Impairment In Healthy Older Individuals Five Years Before Diagnosis, Yang Jiang, Juan Li, Frederick A. Schmitt, Gregory A. Jicha, Nancy B. Munro, Xiaopeng Zhao, Charles D. Smith, Richard J. Kryscio, Erin L. Abner

Behavioral Science Faculty Publications

BACKGROUND: Early prognosis of high-risk older adults for amnestic mild cognitive impairment (aMCI), using noninvasive and sensitive neuromarkers, is key for early prevention of Alzheimer's disease. We have developed individualized measures in electrophysiological brain signals during working memory that distinguish patients with aMCI from age-matched cognitively intact older individuals.

OBJECTIVE: Here we test longitudinally the prognosis of the baseline neuromarkers for aMCI risk. We hypothesized that the older individuals diagnosed with incident aMCI already have aMCI-like brain signatures years before diagnosis.

METHODS: Electroencephalogram (EEG) and memory performance were recorded during a working memory task at baseline. The individualized baseline neuromarkers, …

Stromberg, Glen Mays, Joann Sorra, Jane Brock, Terry Davis, Suzanne Mitchell, Huong Q. Nguyen, Mark V. Williams

Center for Health Services Research Faculty Publications

BACKGROUND: As health systems transition to value-based care, improving transitional care (TC) remains a priority. Hospitals implementing evidence-based TC models often adapt them to local contexts. However, limited research has evaluated which groups of TC strategies, or transitional care activities, commonly implemented by hospitals correspond with improved patient outcomes. In order to identify TC strategy groups for evaluation, we applied a data-driven approach informed by literature review and expert opinion.

METHODS: Based on a review of evidence-based TC models and the literature, focus groups with patients and family caregivers identifying what matters most to them during care transitions, and expert …

Sex Differences And Psychological Stress: Responses To The Covid-19 Pandemic In China, Shiyan Yan, Rui Xu, Terry D. Stratton, Voyko Kavcic, Dan Luo, Fengsu Hou, Fengying Bi, Rong Jiao, Kangxing Song, Yang Jiang

Behavioral Science Faculty Publications

BACKGROUND: About 83,000 COVID-19 patients were confirmed in China up to May 2020. Amid the well-documented threats to physical health, the effects of this public health crisis - and the varied efforts to contain its spread - have altered individuals' "normal" daily functioning. These impacts on social, psychological, and emotional well-being remain relatively unexplored - in particular, the ways in which Chinese men and women experience and respond to potential behavioral stressors. Our study investigated sex differences in psychological stress, emotional reactions, and behavioral responses to COVID-19 and related threats among Chinese residents.

METHODS: In late February (2020), an anonymous …

Modes Of Transmission Of Severe Acute Respiratory Syndrome-Coronavirus-2 (Sars-Cov-2) And Factors Influencing On The Airborne Transmission: A Review, Mahdieh Delikhoon, Marcelo I. Guzman, Ramin Nabizadeh, Abbas Norouzian Baghani

Chemistry Faculty Publications

The multiple modes of SARS-CoV-2 transmission including airborne, droplet, contact, and fecal–oral transmissions that cause coronavirus disease 2019 (COVID-19) contribute to a public threat to the lives of people worldwide. Herein, different databases are reviewed to evaluate modes of transmission of SARS-CoV-2 and study the effects of negative pressure ventilation, air conditioning system, and related protection approaches of this virus. Droplet transmission was commonly reported to occur in particles with diameter >5 µm that can quickly settle gravitationally on surfaces (1–2 m). Instead, fine and ultrafine particles (airborne transmission) can stay suspended for an extended period of time (≥2 h) …

Maternal Proximity To Mountaintop Removal Mining And Birth Defects In Appalachian Kentucky, 1997-2003, Daniel B. Cooper

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Background: Extraction of coal through mountaintop removal mining (MTR) alters many dimensions of the landscape, and explosive blasts, exposed rock, and coal washing have the potential to pollute air and water with substances known to increase risk of developmental and birth anomalies. Previous research suggests that infants born to mothers living in MTR coal mining counties have higher prevalence of most types of birth defects.

Objectives: This study seeks to examine further the relationship between MTR activity and birth defects by employing individual level exposure estimation through precise satellite data of MTR activity in the Appalachian region and maternal residence …

Patient Engagement In Patient Portals In Appalachia Versus Surrounding Us Census Regions: An Analysis Of Hints (Health Information National Trends Survey) Data, 2017 - 2020, Heather Lea Tudor

Racial Disparities In Syringe Exchange Program Access In Kentucky, Ankur Bhargava

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Non-white Kentuckians use syringe exchange programs (SEPs) at lower rates than white Kentuckians. This analysis begins by documenting this disparity and then explores several potential causes. Access to SEPs is limited by law as only health departments may operate them. Areas of the state in which SEPs face political opposition are therefore underserved. A consequence of this legal limitation is distance to a SEP may be a barrier to access. Analysis of publicly available data indicates non-white drug users in Kentucky are located closer to syringe exchange programs in urban areas but farther away in rural areas. Proximity to a …

The Witness Project In Whitehall, Oh, Freda Allyson Hucek

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Abstract

The Witness Project (WP) is an evidence-based breast cancer screening intervention that will be implemented in Whitehall, Ohio, at three different churches by the Franklin County Health Department. The WP will target African American women 50-74 years old who are non-compliant with current United States Preventative Services Task Force (USPSTF) breast cancer screening recommendations. African American women face disproportionately higher mortality rates from breast cancer when compared to other racial and ethnic groups in the United States and in Whitehall. African American women are less likely to discuss breast cancer and preventive screening services within their community. The WP …

Investigations Into The Genetics Of Mixed Pathologies In Dementia, Adam Dugan

Theses and Dissertations--Epidemiology and Biostatistics

Alzheimer’s disease (AD) is an irreversible, progressive brain disorder that leads to a loss of memory and thinking skills. While tremendous progress has been made in our understanding of the genetics underlying AD, currently known genetic variants explain only approximately 30% of the heritable risk of developing AD. One hurdle to AD research is that it can only be definitively diagnosed at autopsy, making cruder, clinic-based diagnoses more common. In recent years, several brain pathologies that mimic AD’s clinical presentation have been identified including brain arteriolosclerosis, hippocampal sclerosis (HS), and, most recently, limbic-predominant age-related TDP-43 encephalopathy (LATE). It has become …

An Assessment Of Kentucky Birth Records, Focusing On Early-Onset Hypertensive Disorders Of Pregnancy, Environmental Metal Exposures, And Geocoding Precision, 2008-2017, Courtney J. Walker

Theses and Dissertations--Epidemiology and Biostatistics

Using live and stillbirth records from Kentucky (2008-2017), this dissertation assessed the county-level prevalence and geospatial patterns of early-onset hypertensive disorders of pregnancy (eHDP); examined the geocoding precision of addresses recorded on birth records, and evaluated the association between individual risk factors and environmental metal exposures on eHDP prevalence. After adjusting for maternal demographic factors and pre-existing health conditions, we observed that eHDP prevalence was 38% higher (aPR=1.38, 95%CI:1.16, 1.64) in counties with the highest prevalence of married women (> 53.8%) compared to lower prevalence areas (31.6%) had a 20% higher prevalence of eHDP(aPR=1.20, 95%CI:1.00, 1.44) compared to counties with …

Dietary Assessments And Their Association With Psychological Factors, Inflammation, And Cardiovascular Health Outcomes, Junghee Kang

Theses and Dissertations--Nursing

Cardiovascular diseases (CVDs), a group of disorders of the heart and blood vessels, are the leading cause of death worldwide, causing one-third of deaths each year. Diet is one of the most important behavioral risk factors for CVD. The effects of behavioral risk factors, such as diet, may lead to increased blood pressure, increased blood glucose, raised blood lipids, and overweight and obesity. Inflammation contributes to the development of CVD and can be influenced by diet. Dietary assessment indices can measure diet quality from an individual's dietary intake by scoring food and nutrient intakes. However, the mediation effects of diet …

Evaluating The Incidence Of Melanoma And Lung Cancer Of Current And Former Active-Duty U.S. Military Who Were Deployed In Support Of Operation Enduring Freedom And Operation Iraqi Freedom, Brian Kovacic

Theses and Dissertations--Epidemiology and Biostatistics

The incidence of melanoma and lung cancer has been gradually increasing in the United States over the past three decades with the reputed causes due to etiological and environmental exposures, and tobacco usage. There has been concern that melanoma and lung cancer incidence among military personnel may be associated with deployment to environments with intense sun exposure and increased smoking rates due to post-traumatic stress disorder. The aim of this study was to examine associations between deployment in support of Operation Enduring Freedom (OEF) or Operation Iraqi Freedom (OIF), from 2001 through 2015, with subsequent melanoma and lung cancer incidence. …
