Food Insecurity and Health Care Utilization Among Older Adults in the United States

This study examined the relationships between food insecurity and utilization of four health services among older Americans: office visits, inpatient hospital nights, emergency department visits, and home health care. Nationally representative data from the 2011 and 2012 National Health Interview Survey were used (N = 13,589). Nearly 83.0% of the sample had two or more office visits, 17.0% reported at least one hospital night, 23.0% had at least one emergency room visit, and 8.1% used home health care during the past 12 months. Adjusting for confounders, food-insecure older adults had higher odds of using more office visits, inpatient hospital nights, and emergency department visits than food-secure older adults, but similar odds of home health care utilization. The findings of this study suggest that programs and policies aimed at reducing food insecurity among older adults may have a potential to reduce utilization of health care services.     

Diabetes Burden and Access to Preventive Care in the Rural United States

Context: National databases can be used to investigate diabetes prevalence and health care use. Guideline-based care can reduce diabetes complications and morbidity. Yet little is known about the prevalence of diabetes and compliance with diabetes care guidelines among rural residents and whether different national databases provide similar results.
Purpose: To examine rural-urban differences in the prevalence of diabetes and compliance with guidelines, and to compare the Behavioral Risk Factor Surveillance System (BRFSS) and the Medical Expenditures Panel Survey (MEPS).
Methods: Data for 2001-2002 were analyzed and compared by rural-urban status. Prevalence was calculated as simple unadjusted, weighted unadjusted, and weighted adjusted using a multivariate approach. Results from the 2 databases were compared.
Findings: A slightly higher prevalence of diabetes among rural residents, 7.9% versus 6.0% in MEPS and 7.6% versus 6.6% in BRFSS, was found and persisted after adjustment for age, BMI, insurance coverage, and other demographic characteristics (adjusted OR 1.16 [1.02-1.31] in MEPS; 1.19 [1.01-1.20] in BRFSS). Rural persons in MEPS were less likely to receive an annual eye examination (aOR = 0.85) and a feet check (aOR = 0.89). A significantly ( P < .05) smaller proportion of rural residents in BRFSS received an annual eye examination (aOR = 0.88), feet check (aOR = 0.85), or diabetes education (aOR = 0.83). Rural residents in both datasets were more likely to get a quarterly HbA1c test done.
Conclusion: Rural residents in both datasets had higher prevalence of diabetes. Though not always statistically significant, the trend was to less guideline compliance in rural areas.     

Evaluation of the Effect of a Consumer-Driven Health Plan on Medical Care Expenditures and Utilization

Objective. To compare medical care costs and utilization in a consumer-driven health plan (CDHP) to other health insurance plans.
Study Design. We examine claims and employee demographic data from one large employer that adopted a CDHP in 2001. A quasi-experimental pre–post design is used to assign employees to three cohorts: (1) enrolled in a health maintenance organization (HMO) from 2000 to 2002, (2) enrolled in a preferred provider organization (PPO) from 2000 to 2002, or (3) enrolled in a CDHP in 2001 and 2002, after previously enrolling in either an HMO or PPO in 2000. Using this approach we estimate a difference-in-difference regression model for expenditure and utilization measures to identify the impact of CDHP.
Principal Findings. By 2002, the CDHP cohort experienced lower total expenditures than the PPO cohort but higher expenditures than the HMO cohort. Physician visits and pharmaceutical use and costs were lower in the CDHP cohort compared to the other groups. Hospital costs and admission rates for CDHP enrollees, as well as total physician expenditures, were significantly higher than for enrollees in the HMO and PPO plans.
Conclusions. An early evaluation of CDHP expenditures and utilization reveals that the new health plan is a viable alternative to existing health plan designs. Enrollees in the CDHP have lower total expenditures than PPO enrollees, but higher utilization of resource-intensive hospital admissions after an initially favorable selection.     

Chiropractic in the United States: trends and issues

Chiropractic is the best established of the alternative health care professions. Although marginalized for much of the 20th century, it has entered the mainstream of health care, gaining both legitimacy and access to third-party payers. However, the profession's efforts to validate the effectiveness of spinal manipulative therapy, its principal modality, have yielded only modest and often contrary results. At the same time, reimbursement is shrinking, the number of practitioners is growing, and competition from other healing professions is increasing. The profession's efforts to establish a role in primary care are meeting resistance, and its attempts to broaden its activities in alternative medicine have inherent limitations. Although patients express a high level of satisfaction with chiropractic treatment and politicians are sympathetic to it, this may not be enough as our nation grapples to define the health care system that it can afford.     

Young Adults' Health Care Utilization and Expenditures Prior to the Affordable Care Act

PurposeTo examine young adults' health care utilization and expenditures prior to the Affordable Care Act.MethodsWe used 2009 Medical Expenditure Panel Survey to (1) compare young adults' health care utilization and expenditures of a full-spectrum of health services to children and adolescents and (2) identify disparities in young adults' utilization and expenditures, based on access (insurance and usual source of care) and other sociodemographic factors, including race/ethnicity and income.ResultsYoung adults had (1) significantly lower rates of overall utilization (72%) than other age groups (83%–88%, p < .001), (2) the lowest rate of office-based utilization (55% vs. 67%–77%, p < .001) and (3) higher rate of emergency room visits compared with adolescents (15% vs. 12%, p < .01). Uninsured young adults had high out-of-pocket expenses. Compared with the young adults with private insurance, the uninsured spent less than half on health care ($1,040 vs. $2,150/person, p < .001) but essentially the same out-of-pocket expenses ($403 vs. $380/person, p = .57). Among young adults, we identified significant disparities in utilization and expenditures based on the presence/absence of a usual source of care, race/ethnicity, home language, and sex.ConclusionsYoung adults may not be utilizing the health care system optimally by having low rates of office-based visits and high rates of emergency room visits. The Affordable Care Act provision of insurance for those previously uninsured or under-insured will likely increase their utilization and expenditures and lower their out-of-pocket expenses. Further effort is needed to address noninsurance barriers and ensure equal access to health services.     

Federal Expenditures on Maternal and Child Health in the United States

The goals of this study are to estimate federal maternal and child health (MCH) expenditures and identify their sources. This analysis is intended to provide a broad view of MCH funding appropriations and a basis for discussion of whether funds could be better utilized for the benefit of the population served. Data on federal maternal and child health expenditures for fiscal year (FY) 2006 were derived from examining federal legislation, department/agency budgets, and various web-based program documents posted by federal agencies. Based on selected criteria, we identified programs targeting children under 21 or pregnant/parenting women within the United States. The funding levels of agency programs for maternal and child health activities were determined and the programs briefly summarized. The identifiable funding for maternal and child health programs in FY 2006 approached $57.5 billion dollars. Funding sources for maternal and child health were concentrated within the U.S. Department of Health and Human Services, but spread across several different agencies within the department and in the Departments of Defense, Education, Agriculture, Housing and Urban Development, and the Environmental Protection Agency. Multiple agencies and offices often funded related activities, without evidence of a common underlying strategy. Federal maternal and child health funding mechanisms may lead to a fragmentation in maternal and child health activities. The funding and service delivery apparatus would benefit from an integrative MCH infrastructure approach to pediatric research, service delivery, and data collection/access that incorporates life-course and social/environmental determinants perspectives.     

Societal and Individual Determinants of Medical Care Utilization in the United States

A theoretical framework for viewing health services utilization is presented, emphasizing the importance of the (1) characteristics of the health services delivery system, (2) changes in medical technology and social norms relating to the definition and treatment of illness, and (3) individual determinants of utilization. These three factors are specified within the context of their impact on the health care system. Empirical findings are discussed which demonstrate how the framework might be employed to explain some key patterns and trends in utilization. In addition, a method is suggested for evaluating the utility of various individual determinants of health services utilization used in the framework for achieving a situation of equitable distribution of health services in the United States.     

Contextual Determinants of Maternal Health Care Service Utilization in Nigeria

Despite the high maternal mortality ratio in Nigeria, the use of maternal health care services is very poor. Attempts to explain this situation has focused on individual level factors and the influence of community contextual factors have not received much attention. This study examined the relation of community factors to the use of antenatal care in Nigeria, and explored whether community factors moderated the association between individual characteristics and antenatal care visits. Data were drawn from the 2008 Nigeria Demographic and Health Survey among 16,005 women aged 15–49 years who had had their last delivery in the five years preceding the survey. Results from multi-level models indicated that living in communities with a high proportion of women who delivered in a health facility was associated with four or more antenatal care visits. Residence in high-poverty communities decreased the likelihood of antenatal care attendance. Living in communities with a high proportion of educated women was not significantly related to antenatal care visits. Community factors acted as moderators of the association between educational attainment and antenatal care attendance. Improvement in antenatal care utilization may therefore be enhanced by targeting poverty reduction programs and increasing health facility delivery in disadvantaged communities.     

Telephone survey to assess influenza-like illness, United States, 2006

Although current national response plans assume that most influenza-infected patients would stay home during a pandemic, surveillance systems might be overwhelmed and unable to monitor their health status. We explored the feasibility of using a nationwide telephone survey to monitor at-home patients. Of randomly selected adults surveyed during low influenza activity months (April-October 2006, surveillance weeks 17-41), 86% (7,268/8,449) agreed to answer questions about health status and influenza-like illness symptoms. Three percent (230/7,628) self-reported "flu." A subset (0.9%, 68/230) self-reported fever. In comparison, the Centers for Disease Control and Prevention's Sentinel Provider Network reported clinical influenza-like illness rates of 1.2%, 0.9%, and 1.2% for weeks 17, 20, and 41, respectively. The consistency between information obtained by telephone and surveillance data warrants further studies to determine whether telephone surveys can accurately monitor health status during seasonal influenza peaks and to augment current surveillance systems during a pandemic.     

The Boomers Are Coming: A Total Cost of Care Model of the Impact of Population Aging on Health Care Costs in the United States by Major Practice Category

Objective. To project the impact of population aging on total U.S. health care per capita costs from 2000 to 2050 and for the range of clinical areas defined by Major Practice Categories (MPCs).
Data Sources. Secondary data: HealthPartners health plan administrative data; U.S. Census Bureau population projections 2000–2050; and MEPS 2001 health care annual per capita costs.
Study Design. We calculate MPC-specific age and gender per capita cost rates using cross-sectional data for 2002–2003 and project U.S. changes by MPC due to aging from 2000 to 2050.
Data Collection Methods. HealthPartners data were grouped using purchased software. We developed and validated a method to include pharmacy costs for the uncovered.
Principal Findings. While total U.S. per capita costs due to aging from 2000 to 2050 are projected to increase 18 percent (0.3 percent annually), the impact by MPC ranges from a 55 percent increase in kidney disorders to a 12 percent decrease in pregnancy and infertility care. Over 80 percent of the increase in total per capita cost will result from just seven of the 22 total MPCs.
Conclusions. Understanding the differential impact of aging on costs at clinically specific levels is important for resource planning, to effectively address future medical needs of the aging U.S. population.     

Care From Family Physicians Reported by Pregnant Women in the United States

PURPOSE

We describe the proportion of family physicians providing care of any sort to pregnant women in the United States from 2000 to 2009.

METHODS

We used a repeat, cross-sectional design with data from the nationally representative Integrated Health Interview Series (2000–2009) for respondents who reported being pregnant at the time of the survey (N = 3,204). Using multivariate logistic regression, we modeled changes over time in pregnant women’s reports of care from family physicians. We used interaction terms to test for regional differences in trends.

RESULTS

Approximately one-third of pregnant women reported having seen or talked to a family physician for medical care during the prior year, a percentage that remained stable for the period of 2000 to 2009 (adjusted odds ratio for annual change = 1.006). Most pregnant women reported care from multiple types of clinicians, including family physicians, obstetrician-gynecologists, midwives, nurse practitioners, and physician assistants. There were regional differences in trends in family physician care; pregnant women in the North Central United States increasingly reported care from family physicians, whereas women in the South reported a decline (6.7% annual increase vs 4.7% annual decrease, P ≥.001).

CONCLUSIONS

Trends in family medicine care for pregnant women have remained steady for the nation as a whole, but they differ by region of the United States. Most pregnant women reported care from multiple clinicians, highlighting the importance of care coordination for this patient population.     

Acculturation and Health Care Utilization among Mexican Heritage Women in the United States

With the increasing Latino population in the United States, it is critical to examine the influence of the process of acculturation on health care practices and utilization. The purpose of this study was to evaluate the relationship between acculturation level and post-partum visit (PPV) compliance among Latinas participating in a larger psycho-educational intervention aimed at encouraging women to engage in positive healthcare practices. Acculturation was measured with the Bicultural Involvement Questionnaire which assigned participants to five categories: Assimilated, Separated, Moderate, Bicultural and Alienation. Logistic Regression analyses were conducted to predict post-partum visit attendance. Odds ratios and relative risk of not attending the post-partum visit are presented. Results suggest women in the Separation and Assimilation groups were less likely than bicultural group members to attend the PPV. The only other variable that was significant in this analysis is the group condition, indicating that the intervention group was more likely to attend the PPV than the control group. Women identifying as bicultural seem to participate more actively in their own healthcare as they draw on the cultural assets that have a positive influence on informal health practices, such as healthy eating and refraining from drug use. Bicultural group members can also use formal skills related to language and knowledge of the dominant culture to help effectively navigate the healthcare system. Implications for research, intervention and practice are discussed to improve healthcare practices and increase utilization among Latinas.     

Influenza epidemics in the United States, France, and Australia, 1972-1997

Influenza epidemics occur once a year during the winter in temperate areas. Little is known about the similarities between epidemics at different locations. We have analyzed pneumonia and influenza deaths from 1972 to 1997 in the United States, France, and Australia to examine the correlation over space and time between the three countries. We found a high correlation in both areas between France and the United States (correlation in impact, Spearman's r= 0.76, p < 0.001, and test for synchrony in timing of epidemics, p < 0.001). We did not find a similar correlation between the United States and Australia or between France and Australia, when considering a systematic half-year lead or delay of influenza epidemics in Australia as compared with those in the United States or France. These results support a high correlation at the hemisphere level and suggest that the global interhemispheric circulation of epidemics follows an irregular pathway with recurrent changes in the leading hemisphere.     

Unintended pregnancy in the United States: incidence and disparities, 2006

Background

The incidence of unintended pregnancy is among the most essential health status indicators in the field of reproductive health. One ongoing goal of the US Department of Health and Human Services is to reduce unintended pregnancy, but the national rate has not been estimated since 2001.

Study Design

We combined data on women's pregnancy intentions from the 2006–2008 and 2002 National Survey of Family Growth with a 2008 national survey of abortion patients and data on births from the National Center for Health Statistics, induced abortions from a national abortion provider census, miscarriages estimated from the National Survey of Family Growth and population data from the US Census Bureau.

Results

Nearly half (49%) of pregnancies were unintended in 2006, up slightly from 2001 (48%). The unintended pregnancy rate increased to 52 per 1000 women aged 15–44 years in 2006 from 50 in 2001. Disparities in unintended pregnancy rates among subgroups persisted and in some cases increased, and women who were 18–24 years old, poor or cohabiting had rates two to three times the national rate. The unintended pregnancy rate declined notably for teens 15–17 years old. The proportion of unintended pregnancies ending in abortion decreased from 47% in 2001 to 43% in 2006, and the unintended birth rate increased from 23 to 25 per 1000 women 15–44 years old.

Conclusions

Since 2001, the United States has not made progress in reducing unintended pregnancy. Rates increased for nearly all groups and remain high overall. Efforts to help women and couples plan their pregnancies, such as increasing access to effective contraceptives, should focus on groups at greatest risk for unintended pregnancy, particularly poor and cohabiting women.     

Racial/Ethnic Disparity Trends in Children's Mental Health Care Access and Expenditures from 2002 to 2007

Objective

To examine trends in disparities in children''s mental health care.

Data

2002–2007 Medical Expenditure Panel Survey.

Study Design

We used the Institute of Medicine (IOM) definition of health care disparities and estimated two-part expenditure models to examine disparity trends in any mental health care use, any outpatient care, and psychotropic drug use, as well as expenditures in these three categories, conditional on use. We used 2-year longitudinal panel data to determine disparities in care initiation among children with unmet need.

Principal Findings

Assessing trends over time between 2002 and 2007, we identified that disparities persist for blacks and Latinos in receipt of any mental health care, any outpatient care, and any psychotropic drug use. Among those with positive mental health care expenditures, Latino–white disparities in overall mental health care expenditures increased over time. Among children with unmet need, significant disparities in initiation of an episode of mental health care were found, with whites approximately twice as likely as blacks and Latinos to initiate care.

Conclusions

Disparities in children''s mental health care use are persistent and driven by disparities in initiation, suggesting policies to improve detection or increase initial access to care may be critical to reducing disparities.     

Challenges and Opportunities of Health Care Supply Chain Management in the United States

This article explores current supply chain management challenges and initiatives and identifies problems that affect supply chain management success in the U.S. health-care industry. In addition, it investigates the impact of health care supply chain management (SCM) initiatives on the overall organizational effectiveness. The attitudinal results, as well as the performance results presented in this study support the claim of health care proponents that the SCM allows organizations to reduce cost, improve quality, and reduce cycle time, and leads to high performance.
