Influence of insurance coverage on delays in seeking emergency care in patients with acute chest pain

Critical Care Implications of the Affordable Care Act

OBJECTIVES

To provide an overview of key elements of the Affordable Care Act. To evaluate ways in which the Affordable Care Act will likely impact the practice of critical care medicine. To describe strategies that may help health systems and providers effectively adapt to changes brought about by the Affordable Care Act.

DATA SOURCES AND SYNTHESIS

Data sources for this concise review include search results from the PubMed and Embase databases, as well as sources relevant to public policy such as the text of the Patient Protection and Affordable Care Act and reports of the Congressional Budget Office. As all of the Affordable Care Act's provisions will not be fully implemented until 2019, we also drew upon cost, population, and utilization projections, as well as the experience of existing state-based healthcare reforms.

CONCLUSIONS

The Affordable Care Act represents the furthest reaching regulatory changes in the U.S. healthcare system since the 1965 Medicare and Medicaid provisions of the Social Security Act. The Affordable Care Act aims to expand health insurance coverage to millions of Americans and place an emphasis on quality and cost-effectiveness of care. From models which link pay and performance to those which center on episodic care, the Affordable Care Act outlines sweeping changes to health systems, reimbursement structures, and the delivery of critical care. Staffing models that include daily rounding by an intensivist, palliative care integration, and expansion of the role of telemedicine in areas where intensivists are inaccessible are potential strategies that may improve quality and profitability of ICU care in the post-Affordable Care Act era.

Postoperative mortality after surgery for brain tumors by patient insurance status in the United States

OBJECTIVE

To examine whether being uninsured is associated with higher in-hospital postoperative mortality when undergoing surgery in the United States for a brain tumor.

DESIGN

Retrospective cohort study using the Nationwide Inpatient Sample, January 1, 1999, through December 31, 2008.

SETTING

The Nationwide Inpatient Sample contains all inpatient records from a stratified sample of 20% of hospitals in 37 states.

PATIENTS

A total of 28,581 patients, aged 18 to 65 years, who underwent craniotomy for a brain tumor. Three groups were studied: Medicaid recipients and privately insured and uninsured patients.

MAIN OUTCOME MEASURE

The main outcome measure was in-hospital postoperative death. Associations between this outcome and insurance status were examined within the full cohort and within the subset of patients with no comorbidity using Cox proportional hazards models. These models were stratified by hospital to control for any clustering effects that could arise from differing access to care.

RESULTS

In the unadjusted analysis, the mortality rate for privately insured patients was 1.3% (95% CI, 1.1%-1.4%) compared with 2.6% for uninsured patients (95% CI, 1.9%-3.3%; P < .001) and 2.3% for Medicaid recipients (95% CI, 1.8%-2.8%; P < .001). After adjusting for patient characteristics and stratifying by hospital in patients with no comorbidity, uninsured patients still had a higher risk of experiencing in-hospital death (hazard ratio, 2.62; 95% CI, 1.11-6.14; P = .03) compared with privately insured patients. In this adjusted analysis, the disparity was not conclusively present in Medicaid recipients (hazard ratio, 2.03; 95% CI, 0.97-4.23; P = .06).

CONCLUSIONS

Uninsured patients who underwent craniotomy for a brain tumor experienced the highest in-hospital mortality. Differences in overall health do not fully account for this disparity.

Effect of insurance status on patients admitted for acute diverticulitis

AIM

The study aimed to evaluate the relationship between insurance status and the management and outcome of acute diverticulitis in a nationally representative sample.

METHOD

A retrospective cohort analysis of a nationally representative sample of 1 031 665 hospital discharges of patients admitted for acute diverticulitis in the 2006-2009 Nationwide Inpatient Sample (NIS), Healthcare Cost and Utilization Project data set. The main outcome measures included state at presentation (complicated/uncomplicated), management (medical/surgical), time to surgical intervention, type of operation and inpatient death.

RESULTS

In total, 207 838 discharges were identified (including 37.0% with private insurance, 49.3% in Medicare, 5.6% in Medicaid and 5.8% uninsured) representing 1 031 665 total discharges nationally. Medicare patients were more likely to present with complicated diverticulitis compared with private insurance patients (23.8% vs 15.1%). Time to surgical intervention differed by insurance status. After adjusting for patient, hospital and treatment factors, Medicare patients were less likely than those with private insurance to undergo a procedure (Medicare OR = 0.86, 95% CI: 0.82-0.91), while the uninsured were more likely to undergo drainage (OR = 1.30, 95% CI: 1.16-1.46) or a colostomy only (OR = 1.70, 95% CI: 1.24-2.33). All patients without private insurance were more likely to die in hospital (Medicare OR = 1.29, 95% CI: 1.09-1.52; Medicaid OR = 1.55, 95% CI: 1.22-1.97; uninsured OR = 1.41, 95% CI: 1.07-1.87).

CONCLUSION

In a nationally representative sample of patients with acute diverticulitis, patient management and outcome varied significantly by insurance status, despite adjustment for potential confounders. Providers might need to heighten surveillance for complications when treating patients without private insurance to improve outcome.

Insurance status and the care of adult patients 19 to 64 years of age visiting the emergency department

OBJECTIVES

The objective was to determine whether insurance status is associated with the care of patients presenting to the emergency department (ED).

METHODS

This was a retrospective cross-sectional analysis of ED visits using data from the National Hospital Ambulatory Medical Care Survey (NHAMCS; 1999 through 2008). Patients 19 to 64 years of age were categorized as having private insurance, public insurance, or no insurance as their primary insurance. Six components of ED care were assessed: wait time, left prior to discharge, use of diagnostic testing, treatment, instructions for follow-up, and whether the patient had been seen in the past 72 hours.

RESULTS

Nonprivate insurance status was associated with all six components of ED care, including higher proportions of leaving before discharge of patients with public insurance (4.1%, 95% confidence interval [CI]=3.8% to 4.5%) versus patients with no insurance (4.7%, 95% CI=4.2% to 5.1%) or private insurance (2.2%, 95% CI=2.0% to 2.4%; p<0.001). It was also associated with a higher proportion of return visits with 5.1% (95% CI=4.6% to 5.6%) of patients with public insurance versus 4.7% (95% CI=4.1% to 4.6%) of patients with no insurance versus 3.8% (95% CI=3.5% to 4.2%) of patients with private insurance (p<0.001). Patients with public or no insurance also had decreased odds of ED testing compared to those with private insurance (adjusted odds ratio [AOR] for public=0.84, 95% CI=0.80 to 0.88; and AOR for none=0.82, 95% CI=0.79 to 0.86).

CONCLUSIONS

Nonprivate insurance status is associated with different care patterns in adults aged 19 to 64 years visiting the ED. Further studies are needed to evaluate how these disparate care patterns affect health outcomes.

An official American Thoracic Society systematic review: the association between health insurance status and access, care delivery, and outcomes for patients who are critically ill

RATIONALE

One in three Americans under 65 years of age does not have health insurance during some portion of each year. Patients who are critically ill and lack health insurance may be at particularly high risk of morbidity and mortality due to the high cost of intensive care.

OBJECTIVES

To systematically review the medical and nonmedical literature to determine whether differences in critical care access, delivery, and outcomes are associated with health insurance status.

METHODS

Nine electronic databases (inception to 11 April 2008) were independently screened and abstracted in duplicate.

MEASUREMENTS AND MAIN RESULTS

From 5,508 citations, 29 observational studies met eligibility criteria. Among the general U.S. population, patients who were uninsured were less likely to receive critical care services than those with insurance (odds ratio [OR], 0.56; 95% confidence interval [CI], 0.55-0.56). Once admitted to the intensive care unit, patients who were uninsured had 8.5% (95% CI, 6.0-11.1) fewer procedures, were more likely to experience hospital discharge delays (OR 4.51; 95% CI, 1.46-13.93), and were more likely to have life support withdrawn (OR 2.80; 95% CI, 1.12-7.02). Lack of insurance may confer an independent risk of death for patients who are critically ill (OR 1.16; 95% CI, 1.01-1.33). Patients in managed care systems had 14.3% (95% CI, 11.5-17.2) fewer procedures in intensive care, but were also less likely to receive "potentially ineffective" care. Differences in unmeasured confounding factors may contribute to these findings.

CONCLUSIONS

Patients in the United States who are critically ill and do not have health insurance receive fewer critical care services and may experience worse clinical outcomes. Improving preexisting health care coverage, as opposed to solely delivering more critical care services, may be one mechanism to reduce such disparities.

Neighborhood income, health insurance, and prehospital delay for myocardial infarction: the atherosclerosis risk in communities study

BACKGROUND

Outcomes following an acute myocardial infarction (AMI) are generally more favorable if prehospital delay time is minimized.

METHODS

We examined the association of neighborhood household income (nINC) and health insurance status with prehospital delay among a weighted sample of 9700 men and women with a validated, definite, or probable AMI in the Atherosclerosis Risk in Communities (ARIC) community surveillance study (1993-2002). Weighted multinomial regression with generalized estimation equations was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) and to account for the clustering of patients within census tracts.

RESULTS

Low nINC was associated with a higher odds of long vs short delay (OR, 1.46; 95% CI, 1.09-1.96) and medium vs short delay (OR, 1.43; 95% CI, 1.12-1.81) compared with high nINC in a model including age, sex, race, diabetes, hypertension, presence of chest pain, arrival at the hospital via emergency medical service, distance from residence to hospital, study community, and year of AMI event. Meanwhile, compared with patients with prepaid insurance or prepaid plus Medicare, patients with Medicaid were more likely to have a long vs short delay (OR, 1.87; 95% CI, 1.10-3.19) and a medium vs short delay (OR, 1.76; 95% CI, 1.13-2.74).

CONCLUSIONS

Both low nINC and being a Medicaid recipient are associated with longer prehospital delay. Reducing socioeconomic and insurance disparities in prehospital delay is critical because excess delay time may hinder effective care for AMI.

Factors influencing Hong Kong Chinese patients' decision-making in seeking early treatment for acute myocardial infarction

The purpose of this study was to identify, through in-depth interview, factors that influenced 27 Hong Kong Chinese patients' decision-making in seeking early treatment for acute myocardial infarction (AMI). The median delay time from the onset of symptoms to arrival at the hospital was 15.6 hours for men and 53.7 hours for women. Three major categories emerged from the data: (a) becoming aware of the threat, (b) maintaining a sense of normality, and (c) struggling to mobilize resources. A variety of decisions were made by patients from the onset of chest pain to seeking help. These decisions were heavily influenced by healthcare factors (access to emergency medical service (EMS) and treatment), personal factors (cognitive interpretations of symptoms), sociocultural factors (family situation, cultural beliefs, and practices), and coping strategies.

Womenʼs Delay in Seeking Treatment With Myocardial Infarction

Women, especially those older than 65 years, delay longer than do men before seeking medical treatment for symptoms of an acute myocardial infarction (AMI). The majority of delay time results from the patient's lengthy decision-making processes after symptoms begin and before seeking medical treatment. Effective treatment is time dependent as mortality and morbidity rise with each hour of delay. Therefore, the purpose of this research was 2-fold: (1) to synthesize reported research findings concerning women's reasons for delay in seeking treatment for symptoms of an AMI and (2) to identify areas for further research. Using Cooper's (Synthesizing Research. 3rd ed. London: Sage; 1998) framework for integrative review, this manuscript synthesized the literature from 48 reports published from 1995 to 2003 to describe the primary reason(s) for women's prehospital delay. Three categories emerged to explain why women delay in seeking treatment: (1) clinical, (2) sociodemographic, and (3) psychosocial factors. These factors are found to be multifaceted and complex. The most significant reasons for delay in seeking treatment for symptoms of AMI are the following: atypical presentation of symptoms, severity of presenting symptoms, presence of other chronic illnesses that confused acute symptoms, correct attribution or labeling of symptoms to the heart, perceived seriousness of the symptoms, beliefs of low self-perceived vulnerability to heart attack, and engagement in various other coping mechanisms. This synthesis identified and clarified the current state of science regarding women's prehospital delay in seeking treatment for symptoms of an AMI. Areas for future research are also discussed.

Resources, use, and regionalization of pediatric cardiac services

Care for children with congenital heart disease requires specialized services and various healthcare resources. The purpose of this article is to provide an updated overview of healthcare resources for infants and children with heart disease. In 2001, there were 1609 certified pediatric cardiologists in the United States. The ratio was approximately 45,000 children younger than 18 years per pediatric cardiologist. It is estimated that more than 19,000 cardiac surgeries are performed in children younger than 18 years in the United States each year. This article also reviews the effect of patient characteristics on access to healthcare and use of pediatric cardiac services, and discusses issues related to optimal use of these resources and the development of an organized approach toward service management by regionalization. The authors believe that improved access to high-quality facilities and providers coupled with thoughtful changes in the healthcare delivery system represent an excellent opportunity for optimizing outcomes for children with heart disease.
