mHealth Apps Use and Their Associations With Healthcare Decision-Making and Health Communication Among Informal Caregivers: Evidence From the National Cancer Institute's Health Information National Trends Survey.

PURPOSE: The current study investigates associations between mHealth apps and healthcare decision-making and health communication among informal caregivers in the US. DESIGN: Cross-sectional study employing secondary data. SETTING: The Health Information National Trends Survey (HINTS5, Cycles 2 through 4, 2018 - 2020). SAMPLE: Self-identified informal caregivers (n = 1386; had mHealth apps = 61.3%, female = 63.2%, some college or more in education = 80.3%) who reported owning at least a smartphone or a tablet computer (i.e., ownership of a "smart device"). MEASURES: Sociodemographic characteristics, reports of having mHealth apps, smart device utilization in healthcare decision-making and health communication. ANALYSIS: Accounting for the complex design features of the HINTS data, we constructed multiple hierarchical logistic regressions to compute adjusted odds ratios (aOR) and their 95% confidence intervals (CI). RESULTS: Compared to caregivers without mHealth apps, those with the apps had higher odds of utilizing their smart devices to make a health-related decision, such as how to treat a disease or a medical condition (aOR = 1.65; 95% CI: 1.13-2.39, P < .01), or engage in health-related discussions with a healthcare provider (aOR = 2.36; 95% CI: 1.54-3.61, P < .001). CONCLUSION: Having mHealth apps was associated with a higher likelihood of using smart devices in healthcare decision-making and health communication by informal caregivers. Empowering caregivers to make informed health-related decisions and communicate effectively with healthcare providers are both crucial to health promotion and well-being. Future studies should investigate facilitators as well as barriers to using mHealth apps and smart devices in health-promoting strategies involving informal caregivers.

Impact of the Affordable Care Act on participation in the Supplemental Nutrition Assistance Program among low-income older Medicare beneficiaries.

BACKGROUND: The Affordable Care Act (ACA) provisions, especially Medicaid expansion, are believed to have "spillover effects," such as boosting participation in the Supplemental Nutrition Assistance Program (SNAP) among eligible individuals in the United States (US). However, little empirical evidence exists about the impact of the ACA, with its focus on the dual eligible population, on SNAP participation. The current study investigates whether the ACA, under an explicit policy aim of enhancing the interface between Medicare and Medicaid, has improved participation in the SNAP among low-income older Medicare beneficiaries. METHODS: We extracted 2009 through 2018 data from the US Medical Expenditure Panel Survey (MEPS) for low-income (≤ %138 Federal Poverty Level [FPL]) older Medicare beneficiaries (n = 50,466; aged ≥ 65), and low-income (≤ %138 FPL) younger adults (aged 20 to < 65 years, n = 190,443). MEPS respondents of > %138 FPL incomes, younger Medicare and Medicaid beneficiaries, and older adults without Medicare were excluded from this study. Using a quasi-experimental comparative interrupted time-series design, we examined (1) whether ACA's support for the Medicare-Medicaid dual-eligible program, through facilitating the online Medicaid application process, was associated with an increase in SNAP uptake among low-income older Medicare beneficiaries, and (2) in the instance of an association, to assess the magnitude of SNAP uptake that can be explicitly attributed to the policy's implementation. The outcome, SNAP participation, was measured annually from 2009 through 2018. The year 2014 was set as the intervention point when the Medicare-Medicaid Coordination Office started facilitating Medicaid applications online for eligible Medicare beneficiaries. RESULTS: Overall, the change in the probability of SNAP enrollment from the pre- to post-intervention period was 17.4 percentage points higher among low-income older Medicare enrollees, compared to similarly low-income, SNAP-eligible, younger adults (ß = 0.174, P < .001). This boost in SNAP uptake was significant and more apparent among older White (ß = 0.137, P = .049), Asians (ß = 0.408, P = .047), and all non-Hispanic adults (ß = 0.030, P < .001). CONCLUSIONS: The ACA had a positive, measurable effect on SNAP participation among older Medicare beneficiaries. Policymakers should consider additional approaches that link enrollment to multiple programs to increase SNAP participation. Further, there may be a need for additional, targeted efforts to address structural barriers to uptake among African Americans and Hispanics.

Hospital value-based payment programs and disparity in the United States: A review of current evidence and future perspectives.

Beginning in the early 2010s, an array of Value-Based Purchasing (VBP) programs has been developed in the United States (U.S.) to contain costs and improve health care quality. Despite documented successes in these efforts in some instances, there have been growing concerns about the programs' unintended consequences for health care disparities due to their built-in biases against health care organizations that serve a disproportionate share of disadvantaged patient populations. We explore the effects of three Medicare hospital VBP programs on health and health care disparities in the U.S. by reviewing their designs, implementation history, and evidence on health care disparities. The available empirical evidence thus far suggests varied impacts of hospital VBP programs on health care disparities. Most of the reviewed studies in this paper demonstrate that hospital VBP programs have the tendency to exacerbate health care disparities, while a few others found evidence of little or no worsening impacts on disparities. We discuss several policy options and recommendations which include various reform approaches and specific programs ranging from those addressing upstream structural barriers to health care access, to health care delivery strategies that target service utilization and health outcomes of vulnerable populations under the VBP programs. Future studies are needed to produce more explicit, conclusive, and consistent evidence on the impacts of hospital VBP programs on disparities.

Longitudinal associations between time-varying insomnia symptoms and all-cause health care services utilization among middle-aged and older adults in the United States.

OBJECTIVE: To examine longitudinal associations between time-varying insomnia symptoms (difficulty initiating sleep, difficulty maintaining sleep, early-morning awakenings, and nonrestorative sleep) and all-cause health care services utilization (HSU), including overnight hospital stays, nursing home stays, and home health care services among middle-aged and older adults. DATA SOURCES: The Health and Retirement Study (HRS), a nationwide, population-representative survey of primarily middle-aged and older adults in the United States. STUDY DESIGN: This study is an analysis of prospective data from the HRS for a cohort of 13,168 adults (aged ≥50 years; females = 57.7%). Study participants were followed for 16 years. This study focuses on the associations between time-varying insomnia symptoms, both cumulatively and independently, and repeated HSUs. A marginal structural modeling approach was used to capture time-varying biological, psycho-cognitive, and behavioral health factors, and to adjust for selection bias such as differential loss to follow-up. Generalized estimating equations were employed to compute average marginal effects and their 95% confidence intervals. DATA COLLECTION/EXTRACTION METHODS: We extracted longitudinal data from 2002 through 2018 waves of the HRS. PRINCIPAL FINDINGS: Experiencing higher numbers of insomnia symptoms on a cumulative scale was associated with higher probabilities of HSU. For instance, the likelihood of overnight hospital stays for individuals reporting one symptom increased from 4.7 percentage points on average (95% CI: 3.7-5.6, p < 0.001), to 13.9 percentage points (95% CI: 10.3-17.5, p < 0.001) for those reporting four symptoms, relative to individuals experiencing no insomnia symptoms. Further, experiencing each of difficulty initiating and maintaining sleep, and nonrestorative sleep, as standalone symptoms, was associated with a higher likelihood of HSU when compared to those not experiencing the symptoms. CONCLUSIONS: The results demonstrate the potential consequences and adverse impacts of insomnia symptoms on HSU among middle-aged and older adults. Future investigations should focus on the underlying causes and health systems pathways linking insomnia symptoms to HSU.

Effectiveness of Using Personal Health Records to Improve Recommended Breast Cancer Screening and Reduce Racial and Geographic Disparities Among Women.

This paper examines the effectiveness of using personal health records (PHRs), which contains detailed health information to improve the use of recommended screening mammography among women at potential risk for breast cancer. It also explores the potential of PHR in reducing disparities in recommended mammography use experienced by minority and underserved women. The primary data used for this study were obtained from the 2015 Health Information National Trends Survey, and they were supplemented by the 2016 Area Health Resource Files. The study sample included women aged 40-75 years with no prior diagnosis of cancer. Because the use of PHRs as a key predictor of breast cancer screening may be endogenously determined, we used the instrumental variable (IV) approach to correct for estimation bias. We found a significant and positive association between the use of PHRs and recommended mammography use among women, with the likelihood of mammography screening increasing with more frequent use of PHRs. Furthermore, the effects of PHR use on mammography screening were found to be greater among Hispanic and Black women and those living in non-metropolitan areas compared with White women and those living in metropolitan areas, respectively. The use of PHRs for health information seeking can empower women at potential risk for breast cancer to participate in recommended screening mammography, particularly among those underserved and racial/ethnic minorities. Policymakers should consider developing policies and programs that can promote PHR use by women, especially medically underserved and minority women.

Access to Broadband Internet and its Utilization for Health Information Seeking and Health Communication among Informal Caregivers in the United States.

Informal caregivers provide unpaid care to their physically or mentally ill loved ones and play a critical role in the healthcare delivery. eHealth tools, including the broadband internet, can facilitate care processes and impact the caregiving burden through seeking health information and health communication. This study examines the predictors of access to broadband internet and the factors associated with health information seeking and health communication among informal caregivers with broadband internet. We used data from cycles 1 and 2 of the Health Information National Trends Survey (HINTS 5) and employed generalized linear regression models with the maximum likelihood estimation. Specifically, we performed a two-part model: (1) a logistic regression model of broadband internet access among all caregivers (n = 929) and (2) a logistic regression model of health information seeking and health communication among caregivers with broadband internet access (n = 404). We found that caregivers who were younger (18-34 years versus 45+ years), female (versus male), and those who were divorced/widowed/separated (versus singles) were less likely to have broadband internet access. While those who were married/living as married (versus singles), with higher incomes (≥$100,000 versus <$35,000), and those living in metropolitan areas were more likely to have broadband internet access. Among caregivers with broadband internet access, younger, female, non-Hispanic white caregivers, and those with higher levels of education and income, as well as those who cared for cancer patients, were more likely to seek health information for someone else. Additionally, caregivers aged 35-39 years and those with more education were more likely to look for health information for themselves than their counterparts. Furthermore, caregivers who were aged 40-44 years, females, divorced/widowed/separated, those with higher incomes, and those who cared for patients with Alzheimer's, confusion, and dementia were more likely to communicate electronically with a provider. The results suggest disparities in broadband internet access and indicate variations in factors associated with health information seeking and health communication. The findings underscore the need to address barriers attributed to the digital divide among informal caregiving groups.

Economic Contributions of a College of Pharmacy to the Surrounding Communities and State.

Objective. To quantify the monetary value of economic contributions of a state-funded college of pharmacy as it pursues its missions of teaching, research, service, and patient care. Methods. An economic analysis was performed by applying the Impact Analysis for Planning (IMPLAN) Economic Input-Output Model to financial and enrollment data of the University of Tennessee Health Science Center College of Pharmacy. Results. A total of $94.1 million was attributed to the college in fiscal year 2018, which included $50.7 million of total direct expenditures by the college, its students, and visitors; the indirect effect of over $17 million; and the induced effect of $26.4 million. The college directly employed 117 full-time equivalent employees and 39 pharmacy residents, and supported 763 additional jobs through the economic activities it stimulated. In addition, the presence of the college and its economic contribution enabled federal, state, and local taxing authorities to collect $12 million in tax revenues to support government and public programs. Conclusion. Demonstrating the economic value of colleges of pharmacy is critical when seeking support from campus administrators, state legislators, charitable foundations, government agencies, and industry.

Mobile Health Application and e-Health Literacy: Opportunities and Concerns for Cancer Patients and Caregivers.

Health literacy is critical for cancer patients as they must understand complex procedures or treatment options. Caregivers' health literacy also plays a crucial role in caring for cancer patients. Low health literacy is associated with low adherence to medications, poor health status, and increased health care costs. There is a growing interest in the use of mobile health applications (apps) to improve health literacy. Mobile health apps can empower underserved cancer patients and their caregivers by providing features or functionalities to enhance interactive patient-provider communication and to understand medical information more readily. Despite the potentiality of improving health literacy through mobile health apps, there exist several related concerns: no equal access to mobile technology, no familiarity or knowledge of using mobile health apps, and privacy and security concerns. These elements should be taken into account for health policy making and mobile apps design and development. Importantly, mobile apps should be developed with the goal of achieving a high range of user access by considering all health literacy level and various cultural and linguistic needs.

The Role of Gender in Cost-Related Medication Nonadherence Among Patients with Diabetes.

OBJECTIVE: Under 50% of type 2 diabetic patients achieve the recommended glycemic control. One barrier to glycemic control is patients' cost-related nonadherence to medications. We hypothesize gender differences in medication nonadherence due to costs among diabetic patients. METHODS: US National Health Interview Survey (2011 to 2014) data yielded 5260 males and 6188 females with diabetes for over a year. We applied 2 analytic methods (A and B below) across multiple outcome measures (1 to 4) of medication nonadherence due to cost. The key independent variable was participant's gender. RESULTS: Across methods and measure, females consistently report significantly higher rates of medication nonadherence due to costs. Pearson's χ2 showed that female patients were more likely to (1) skip medication (13.5%-10.2%; P < .001), take less than prescribed medication (13.9%-10.5%; P < .001), delay filling prescriptions (16.8%-12.5%; P < .001), and ask doctors to prescribe lower-cost alternative medications (31.8%-28.0%; P < .001). Controlling for covariates, logistic regression models found females more likely to skip medication (OR, 1.30; 95% CI, 1.09-1.55), take less than prescribed medication (OR, 1.26; 95%, CI, 1.06-1.50), delay filling prescriptions, (OR, 1.29; 95% CI, 1.11-1.50), and request lower-cost medication (OR, 1.17; 95% CI, 1.04-1.32). Our results report other factors that influence medication adherence, including socioeconomic and health status variables. CONCLUSIONS: A significant gender-based disparity exists on cost-related nonadherence of medication among diabetic patients. Health care providers and policy-makers should pay close attention to find ways to address cost-related nonadherence of medication among patients with chronic illness, especially among female patients.

National Trends in Hospital Emergency Department Visits among Those with and without Multiple Chronic Conditions, 2007-2012.

Emergency department (ED) visits and the number of adults with multiple chronic conditions (MCC) have been increasing over the last decade, but little is known about the trends in ED use for patients with MCC. This study examined national trends in ED use for those with MCC compared with one chronic condition and no chronic conditions and used data from the 2007-2012 National Emergency Department Sample, limited to patients 45 years old or older. ED visits for encounters with one chronic condition and MCC increased at significantly greater rates than for those with no chronic conditions both overall and for all subgroups examined.

Access to Employee Wellness Programs and Use of Preventive Care Services Among U.S. Adults.

INTRODUCTION: There is little research at the national level on access to employee wellness programs and the use of preventive care services. This study examined the use of seven preventive care services among U.S working adults with access to employee wellness programs. METHODS: The study population comprised 17,699 working adults aged ≥18 years, obtained from the 2015 National Health Interview Survey. Multivariate logistic regression models examined the relationship between access to employee wellness programs and use of seven preventive care services: influenza vaccination, blood pressure check, diabetes check, cholesterol check, Pap smear test, mammogram, and colon cancer screening. Data analysis began in Fall 2016. RESULTS: Overall, 46.6% of working adults reported having access to employee wellness programs in 2015. Working adults with access to employee wellness programs had higher odds of receiving influenza vaccination (OR=1.57, 95% CI=1.43, 1.72, p<0.001), blood pressure check (OR=2.46, 95% CI=2.17, 2.78, p<0.001), diabetes check (OR=1.30, 95% CI=1.12, 1.50, p<0.001), cholesterol check (OR=1.48, 95% CI=1.33, 1.67, p<0.001), and mammogram (OR=1.57, 95% CI=1.24, 1.98, p<0.001). However, there was no significant difference between access to employee wellness programs and the use of Pap smear test and colon cancer screening services. CONCLUSIONS: Using a nationally representative sample of individuals, this study found a positive association between access to employee wellness programs and the use of preventive care services. The results support favorable policies to encourage implementing wellness programs in all worksites, especially those with <50 employees.

Provision of Rehabilitation Services in Residential Care Facilities: Evidence From a National Survey.

OBJECTIVE: To examine the association between organizational factors and provision of rehabilitation services that include physical therapy (PT) and occupational therapy (OT) in residential care facilities (RCFs) in the United States. DESIGN: A cross-sectional, observational study conducted using a national sample from the 2010 National Survey of Residential Care Facilities conducted by the Centers for Disease Control and Prevention's National Center for Health Statistics. SETTINGS: U.S. RCFs. PARTICIPANTS: RCFs (N=2302; weighted sample, 31,134 RCFs). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The association between characteristics of the facilities, director and staff, and residents, and provision of PT and OT services was assessed using multivariate logistic regression analyses. RESULTS: Among all RCFs in the United States, 43.9% provided PT and 40.0% provided OT. Medicaid-certified RCFs, larger-sized RCFs, RCFs with a licensed director, RCFs that used volunteers, and RCFs with higher personal care aide hours per patient per day were more likely to provide both PT and OT, while private, for-profit RCFs were less likely to provide PT and OT. RCFs with a higher percentage of white residents were more likely to provide PT, while RCFs with chain affiliation were more likely to provide OT. CONCLUSIONS: Less than half of the RCFs in the United States provide PT and OT, and this provision of therapy services is associated with organizational characteristics of the facilities. Future research should explore the effectiveness of rehabilitation services in RCFs on residents' health outcomes.

Does Cost-Related Medication Nonadherence among Cardiovascular Disease Patients Vary by Gender? Evidence from a Nationally Representative Sample.

INTRODUCTION: Cardiovascular disease (CVD) is a leading cause of death and disability as well as a major burden on the U.S. healthcare system. Cost-related medication nonadherence (CRN) to prescribed medications is common among patients with CVD. This study examines the gender differences in CRN among CVD patients. METHODS: We used 2011 to 2014 data from the National Health Interview Survey, an annual, cross-sectional, nationally representative household survey of the noninstitutionalized U.S. civilian population (≥18 years of age). Based on Andersen's model of health services utilization, multivariate logistic regressions were estimated to examine the effect of gender on the primary composite outcome of CRN which was identified if any of the following types of CRN were reported: 1) skipped medication doses to save money, 2) took less medication to save money, and 3) delayed prescription filling to save money. RESULTS: Among CVD patients who had used a prescription medication in the last 12 months, 10.0% skipped medication doses, 10.6% took less medication, and 12.8% delayed filling their prescriptions. After adjusting for confounding factors, gender was found to be significantly associated with the composite outcome of CRN among CVD patients. Women were 1.54 times (95% confidence interval, 1.33-1.77) more likely to have any of the types of CRN compared with men. CONCLUSION: There are significant gender disparities in CRN among CVD patients. More support for and closer monitoring of CRN is needed for disadvantaged groups, especially women with limited resources.

Too Much or Too Little? How Much Control Should Patients Have Over EHR Data?

Electronic health records (EHRs) have been promoted as a mechanism to overcome the fragmented healthcare system in the United States. The challenge that is being discussed is the rights of the patient to control the access to their EHRs' data and the needs of healthcare professionals to know health data to make the best treatment decisions for their patients. The Federal Trade Commission has asked those who store consumer information to comply with the Fair Information Practice Principles. In the EHR context, these principles give the rights to the patient to control who can see their health data and what components of the data are restricted from view. Control is not limited to patients, as it also includes parents of adolescent children. We suggest that the ongoing policy discussion include consideration of the precise questions patients will be asked when a need for data sharing arises. Further, patients should understand the relative risks that they face, and the degree to which their decisions will (or will not) significantly reduce the risk of a data breach. As various approaches are considered, it is important to address the relative resource requirements and the associated costs of each option.

Use of Mobile Health Applications for Health-Seeking Behavior Among US Adults.

This study explores the use of mobile health applications (mHealth apps) on smartphones or tablets for health-seeking behavior among US adults. Data was obtained from cycle 4 of the 4th edition of the Health Information National Trends Survey (HINTS 4). Weighted multivariate logistic regression models examined predictors of 1) having mHealth apps, 2) usefulness of mHealth apps in achieving health behavior goals, 3) helpfulness in medical care decision-making, and 4) asking a physician new questions or seeking a second opinion. Using the Andersen Model of health services utilization, independent variables of interest were grouped under predisposing factors (age, gender, race, ethnicity, and marital status), enabling factors (education, employment, income, regular provider, health insurance, and rural/urban location of residence), and need factors (general health, confidence in their ability to take care of health, Body Mass Index, smoking status, and number of comorbidities). In a national sample of adults who had smartphones or tablets, 36 % had mHealth apps on their devices. Among those with apps, 60 % reported the usefulness of mHealth apps in achieving health behavior goals, 35 % reported their helpfulness for medical care decision-making, and 38 % reported their usefulness in asking their physicians new questions or seeking a second opinion. The multivariate models revealed that respondents were more likely to have mHealth apps if they had more education, health insurance, were confident in their ability to take good care of themselves, or had comorbidities, and were less likely to have them if they were older, had higher income, or lived in rural areas. In terms of usefulness of mHealth apps, those who were older and had higher income were less likely to report their usefulness in achieving health behavior goals. Those who were older, African American, and had confidence in their ability to take care of their health were more likely to respond that the mHealth apps were helpful in making a medical care decision and asking their physicians new questions or for a second opinion. Potentially, mHealth apps may reduce the burden on primary care, reduce costs, and improve the quality of care. However, several personal-level factors were associated with having mHealth apps and their perceived helpfulness among their users, indicating a multidimensional digital divide in the population of US adults.

Paid sick leave is associated with fewer ED visits among US private sector working adults.

CONTEXT: The United States (US) is the only developed country that does not guarantee short-term or longer-term paid sick leave. OBJECTIVE: This study used a multiyear nationally representative database to examine the association between availability of paid sick leave and frequency of emergency department (ED) use among US private sector employees. STUDY SAMPLE: We used the National Health Interview Survey data (2012-2014). The final study sample consists of 42,460 US adults between 18 and 64years of age and working in nongovernmental private sector. RESULTS: Our results suggest that availability of paid sick leave is significantly associated with lower likelihood of ED use, for both moderate (1-3 times/year) and repeated users (4 or more times/year). After controlling for confounding factors, respondents with paid sick leave are 14% less likely to be moderate ED users (adjusted odds ratio, 0.86; 95% CI, 0.79-0.93) and 32% less likely to be repeated ED users (adjusted odds ratio, 0.68; 95% CI, 0.50-0.91). DISCUSSION: Although expansion of health insurance coverage under the Affordable Care Act has not been shown to reduce utilization of high cost health care services such as the ED, our study suggests other factors such as the availability of paid sick leave may do so, by allowing patients to seek care through other more cost-effective mechanisms (eg, primary care providers). To reduce ED utilization, health policymakers should consider alternative reforms including paid sick leave.

Impact of Medicare Part D on Racial Disparities in Adherence to Cardiovascular Medications Among the Elderly.

Medicare Part D improved medication adherence among the elderly, but to date, its effect on disparities in adherence remains unknown. We estimated Part D impact on racial/ethnic disparities in adherence to cardiovascular medications among seniors, using pooled data from the Medical Expenditure Panel Survey (2002-2010) on 14,221 Medicare recipients (65+ years) and 3,456 near-elderly controls (60-64 years). Study sample included White, Black, or Hispanic respondents who used at least one cardiovascular medication. Twelve-month adherence was measured as having an overall proportion of days covered ≥80%. Adherence disparities were defined according to the Institute of Medicine framework. Using difference-in-differences logistic regression, we found Part D to be associated with a 16-percentage-point decrease in the White-Hispanic disparity in overall adherence among seniors, net of the change among controls. Black-White disparities worsened only among men, by 21 percentage points. Increasing access and improving quality of medication use among disadvantaged seniors should remain a policy priority.

Insurance impact on nonurgent and primary care-sensitive emergency department use.

OBJECTIVES: To analyze the relationship between insurance and the likelihood of a nonurgent or primary care-sensitive (PCS) emergency department (ED) visit. STUDY DESIGN: Retrospective cohort study. METHODS: The probabilities of nonurgent and PCS ED visits were derived on the basis of the New York University ED Classification Algorithm. We constructed a logit quasi-likelihood model to examine the insurance impact using 2008 Tennessee Hospital Outpatient Discharge Data. RESULTS: Among a total of 2,177,955 ED visits in the analysis, uninsured status was significantly associated with the likelihood that an ED visit was nonurgent or PCS. These associations were different for men and women and across major racial groups. On average, uninsured status was associated with an increased probability of 0.038 of being nonurgent and 0.054 of being PCS, relative to private insurance status. The corresponding numbers for public insurance status were 0.060 and 0.075, respectively. For nonurgent or PCS probabilities that are not close to 0, higher nonurgent or PCS likelihoods corresponded to lower ED cost per visit to third-party insurers and patients. CONCLUSIONS: Lack of insurance was associated with a higher probability of a nonurgent or PCS ED visit when compared with private insurance. When uninsured individuals gain coverage under the Affordable Care Act through either Medicaid expansion (public coverage) or insurance exchanges (private coverage), the average nonurgent or PCS probabilities could change either way given the opposite effects of public and private insurance coverage. If a lower nonurgent or PCS likelihood materialized, it could be associated with higher ED costs.

Trends in potentially avoidable hospitalizations among adults in Tennessee, 1998-2006.

BACKGROUND: Potentially avoidable hospitalizations are inpatient admissions for certain conditions, called Ambulatory Care Sensitive Conditions (ACSCs), which can potentially be prevented by effective outpatient treatment of individuals who actively participate in their own care and engage in responsible personal behavior. Changes in the rates of ACSC hospitalizations over time may signal an improvement or deterioration in the quality and effectiveness of ambulatory care. These long-term trends may also suggest changes in the underlying factors such as lifestyle choices and dietary practices of individuals and families. OBJECTIVE: This study presents data from the Tennessee Hospital Discharge Datasets on changes in ACSC hospitalizations as a percent of all hospitalizations for 1998-2006. METHODS: Retrospective analysis of administrative data based on the UB-92 claims forms submitted by all short-term acute-care hospitals in Tennessee. RESULTS: Total ACSC hospitalizations in Tennessee increased by 4.2 percent between 1998 and 2006, while the total costs for ACSC hospitalizations decreased by 1.8 percent in constant 2006 dollars. In comparison, total admissions for all conditions increased by 15 percent during 1998-2006 while total hospital costs for all conditions increased by 21 percent. The rate of increase in ACSC hospitalization varied according to patient's race, insurance type, and whether the patient's health plan is managed care or fee-for-service. ACSC patients admitted through an emergency department outnumbered their counterparts who were not admitted through an emergency department by a factor of more than two throughout 1998-2006. CONCLUSIONS: Our analysis of long-term trends of ACSC hospitalizations in Tennessee reveals a mixed bag of good news and bad news. In 1998-2006, ACSC hospitalizations rose at a much lower rate than overall hospitalizations for all conditions. Meanwhile, the costs of ACSC hospitalization in 2006 constant dollars decreased while the costs of overall hospitalizations increased. Minority groups such as blacks and patients insured under TennCare did not experience much decline in ACSC hospitalizations, especially in the rates of chronic ambulatory-care sensitive conditions, when compared with their white and commercially-insured counterparts. Patients whose care was managed experienced smaller declines in ACSC hospitalizations than those not under managed care. Finally, the number of ACSC hospitalizations admitted through an ED outnumbered those admitted through the regular hospital admission department during the study period, and the gap between the two sources of admissions grew larger over time.
