Medicaid HMO enrollees in the emergency room: use of nonemergency care

A Value-Based Comparison of the Management of Ambulatory Respiratory Diseases in Walk-in Clinics, Primary Care Practices, and Emergency Departments: Protocol for a Multicenter Prospective Cohort Study

BACKGROUND

In Canada, 30%-60% of patients presenting to emergency departments are ambulatory. This category has been labeled as a source of emergency department overuse. Acting on the presumption that primary care practices and walk-in clinics offer equivalent care at a lower cost, governments have invested massively in improving access to these alternative settings in the hope that patients would present there instead when possible, thereby reducing the load on emergency departments. Data in support of this approach remain scarce and equivocal.

OBJECTIVE

The aim of this study is to compare the value of care received in emergency departments, walk-in clinics, and primary care practices by ambulatory patients with upper respiratory tract infection, sinusitis, otitis media, tonsillitis, pharyngitis, bronchitis, influenza-like illness, pneumonia, acute asthma, or acute exacerbation of chronic obstructive pulmonary disease.

METHODS

A multicenter prospective cohort study will be performed in Ontario and Québec. In phase 1, a time-driven activity-based costing method will be applied at each of the 15 study sites. This method uses time as a cost driver to allocate direct costs (eg, medication), consumable expenditures (eg, needles), overhead costs (eg, building maintenance), and physician charges to patient care. Thus, the cost of a care episode will be proportional to the time spent receiving the care. At the end of this phase, a list of care process costs will be generated and used to calculate the cost of each consultation during phase 2, in which a prospective cohort of patients will be monitored to compare the care received in each setting. Patients aged 18 years and older, ambulatory throughout the care episode, and discharged to home with one of the aforementioned targeted diagnoses will be considered. The estimated sample size is 1485 patients. The 3 types of care settings will be compared on the basis of primary outcomes in terms of the proportion of return visits to any site 3 and 7 days after the initial visit and the mean cost of care. The secondary outcomes measured will include scores on patient-reported outcome and experience measures and mean costs borne wholly by patients. We will use multilevel generalized linear models to compare the care settings and an overlap weights approach to adjust for confounding factors related to age, sex, gender, ethnicity, comorbidities, registration with a family physician, socioeconomic status, and severity of illness.

RESULTS

Phase 1 will begin in 2021 and phase 2, in 2023. The results will be available in 2025.

CONCLUSIONS

The end point of our program will be for deciders, patients, and care providers to be able to determine the most appropriate care setting for the management of ambulatory emergency respiratory conditions, based on the quality and cost of care associated with each alternative.

Demographic factors influencing nonurgent emergency department utilization among a Medicaid population

To use administrative medical encounter data to examine nonurgent emergency department (ED) utilization as it relates to member characteristics (i.e., age, gender, race/ethnicity, urbanicity and federal poverty level (FPL)). This 1 year cross-sectional study used medical claims from a managed care organization for Medicaid members enrolled from October 1, 2010 - September 30, 2011. ED encounters occurring during the study period were classified as either urgent or nonurgent using ICD-9 diagnosis codes obtained from medical claims. Examples of urgent diagnoses include head traumas, burns, allergic reactions, poisonings, preterm labor or maternal/fetal distress. A total of 187,263 members aged 2 to 65 years were retained for study. A zero-inflated Poisson regression model examined the influence of member-level characteristics on nonurgent ED utilization, while simultaneously adjusting for all factors. Females were 41 % more likely to have a nonurgent ED visit (p ≤ 0.0001). Members ages 50-65 were least likely to have a nonurgent ED visit (p ≤ 0.0001). White members had higher odds of having at least one nonurgent ED visit (p ≤ 0.0002). Rural members were 7.7 % less likely to have a nonurgent ED visit. Members in the 400 % + FPL category were less likely to seek nonurgent care from an ED (p ≤ 0.0001). A nonurgent ED visit occurs when care is sought at an ED that could have been handled in a primary care setting. Approximately 30-50 % of all ED visits in the United States are considered nonurgent. This study supports the need to determine factors associated with misuse of ED services for nonurgent care. Demographic factors significantly impacting nonurgent ED utilization include gender, age, race/ethnicity, urbanicity and percent of the FPL. Results may be useful in ED utilization management efforts.

Demand for hospital emergency departments: a conceptual understanding

BACKGROUND

Emergency departments (EDs) are critical to the management of acute illness and injury, and the provision of health system access. However, EDs have become increasingly congested due to increased demand, increased complexity of care and blocked access to ongoing care (access block). Congestion has clinical and organisational implications. This paper aims to describe the factors that appear to influence demand for ED services, and their interrelationships as the basis for further research into the role of private hospital EDs.

DATA SOURCES

Multiple databases (PubMed, ProQuest, Academic Search Elite and Science Direct) and relevant journals were searched using terms related to EDs and emergency health needs. Literature pertaining to emergency department utilisation worldwide was identified, and articles selected for further examination on the basis of their relevance and significance to ED demand.

RESULTS

Factors influencing ED demand can be categorized into those describing the health needs of the patients, those predisposing a patient to seeking help, and those relating to policy factors such as provision of services and insurance status. This paper describes the factors influencing ED presentations, and proposes a novel conceptual map of their interrelationship.

CONCLUSION

This review has explored the factors contributing to the growing demand for ED care, the influence these factors have on ED demand, and their interrelationships depicted in the conceptual model.

[Influence of the organization of primary care and the socio-demographic characteristics of the population on the demand for municipal emergency dental care]

The scope of this study was to evaluate the influence of the social determinants and the provision of primary care services in relation to the use of emergency dental care services in a medium-sized municipality. Data recorded for the 57,231 users of emergency care between 2007 and 2009, in accordance with age, gender, date and period of dental care, social exclusion indices of the suburb in which they live and the existence of a benchmark oral health team, were used to perform the analysis. Of the total population, 5.24% on average per year used the service during the period under scrutiny, with the 20-49 year age group (63.84%) showing the highest demand and equality between genders for such care. Surgical procedures (54.90%) were the most prevalent with an increasing trend for restorative procedures (62,8%). Users living in areas of greater social exclusion were 4.15 times more likely to seek dental care (p < 0.05). No statistically significant association was found between gender or the existence of an oral health team of the suburb in which they live and the demand for emergency dental care. In conclusion, there was greater recourse to emergency municipal dental care by individuals living in vulnerable areas, proving the importance of such care in diminishing oral health inequality.

Revisiting predictors of parental health care-seeking behaviors for nonurgent conditions at one inner-city hospital

INTRODUCTION

To determine important predictors of why parents seek care for their children at a pediatric emergency department (ED) compared to their child's primary care provider's (PCP's) walk-in clinic.

DESIGN

Cross-sectional study.

SETTING

An inner-city hospital located in New York City, from April 2003 to January 2004.

PARTICIPANTS

A convenience sample of 170 parents with children younger than 18 years, Medicaid beneficiaries, had a PCP, and presented with a nonurgent medical problem either at the pediatric ED or walk-in clinic.

MAIN OUTCOME MEASURE

The main outcome measure was the setting in which parents sought care for their child; odds ratios (ORs) were calculated for parents seeking care in the pediatric ED compared to those seeking care at the walk-in clinic, adjusting for predisposing, enabling, and need-related factors.

RESULTS

Of the 170 parent-child visits, 87 (51%) were seeking care at the ED and 83 (49%) at their child's walk-in clinic. In logistic regression, single parenting was the strongest predictor for seeking care in the ED (OR, 5.54; 95% confidence interval [CI], 1.4-26.9), followed by Hispanic ethnicity (OR, 4.96; 95% CI, 1.43-17.2), low parental perceptions of their child's physical health (OR, 0.90; 95% CI, 0.82-0.99), controlling for number of chronic conditions, parental working status, and satisfaction with their PCP.

CONCLUSIONS

Single parenting, Hispanic ethnicity, and perceptions of health are associated with health care-seeking behaviors in high cost settings among Medicaid beneficiaries. Targeted education programs could be used to influence future site of care.

The Impact of Managed Care Enrollment on Emergency Department Use Among Children With Special Health Care Needs

BACKGROUND

Many states recently have experimented with managed care as a way both to control costs and to enhance continuity of care in their publicly financed programs. A few states have applied managed care models to the care of chronically ill children. One marker for the effects of managed care is changes in use of the emergency department (ED).

OBJECTIVE

We sought to determine whether a managed care program can reduce ED use for children with chronic health problems.

SUBJECTS

We studied chronically ill children who were dually enrolled in Michigan's Title V program for children with special health care needs and Medicaid and who were enrolled in a managed care option at some time during the study period. The managed care model emphasized care coordination and did not include strong financial incentives for utilization and cost control. Sample consisted of 8580 person-months.

METHOD

We used a fixed-effect negative binomial Poisson regression model to compare ED use before and after joining a managed care plan to test whether managed care use was associated with reduced likelihood of ED use.

RESULTS

Managed care enrollment was associated with a 23% reduction in the incidence of ED use among children dually enrolled in Medicaid and Title V.

CONCLUSIONS

A managed care model is associated with statistically significant and substantive reductions in observed use of ED care within an important population of children facing chronic illness.

Networks of care: how Latina immigrants find their way to and through a county hospital

The purpose of this paper is to explore qualitatively the principal problems that Latino women face in getting health care for themselves and their families, how their experiences with the health care system affect them, and how they often overcome obstacles to get health care. Focus group and individual interviews with Latinas in a public hospital in Los Angeles County revealed that Latinas faced many challenges in getting health care for themselves and their families, and, as a result, many felt embarrassed, scolded, helpless, and discouraged from seeking care. Yet they overcame enormous obstacles to get into the system through solidarity with other Latinas, either friends or extended family, and connections with key health service personnel. These networks of care enabled Latinas to access a complicated health care system and offer lessons for providers and policy-makers concerned with improving the delivery of care to this population.

Emergency department use among Michigan children with special health care needs: an introductory study

OBJECTIVE

To describe patterns of emergency department (ED) use among children dual-enrolled in Medicaid and Michigan's Children's Special Health Care Services (CSHCS).

DATA SOURCES

Individual claims and enrollment data from Michigan's Medicaid and CSHCS programs for the period January 1, 1998, to June 30, 1999. Claims data were linked with eligibility data and then used to develop a 100 percent sample of claims for individuals enrolled in both Medicaid and CSHCS.

STUDY DESIGN

Poisson regression analysis was used to examine the rate of ED use for dual-enrolled children. A time-varying hazard analysis was also used to examine the impact of changes over time. The key variables were gender, age, race, county of residence, Medicaid eligibility category, and qualifying diagnosis.

PRINCIPAL FINDINGS

Dual-enrolled children under one year of age, and those with qualifying diagnoses of anemia, hemophilia, asthma, epilepsy, and juvenile diabetes displayed especially high rates of ED use. Significant geographic variation in ED use remained after controlling for qualifying diagnoses, race/ethnicity, and other factors. African Americans displayed higher rates of ED utilization than non-Hispanic whites. Supplemental Security Income (SSI) recipients demonstrated higher utilization than other groups.

CONCLUSIONS

Children dually enrolled in CSHCS and Medicaid face diverse challenges of both poverty and chronic illness. Differences in patterns of use highlight the importance, but also the difficulty, of developing systems of care to manage complex chronic conditions in low-income populations.

The importance of outcomes research in pediatric emergency medicine

Applying the methods and tools of outcomes research, "evaluation of the impact of health care on the health outcomes or 'end results' of patients and populations," to the clinical domain of emergency services for children offers an important strategic opportunity for addressing the questions that confront all health care services: What works? For which patients? At what cost? From whose perspective? Although the important questions to address are extensive, much of the intersection between emergency services and outcomes research remains unexplored. Important challenges for researchers intrigued by the opportunities at this intersection of fields include: 1) clear definition of the scope of emergency services; 2) consideration of the appropriate end-point of emergency services-the entire episode of illness and/or services provided within the emergency setting; 3) selection and development of measures that incorporate children's and families' perspectives; and 4) a clear focus on linking research findings with strategies for improving outcomes and informed decision making. This essay will provide an overview of accomplishments and challenges from the field of outcomes research, suggest important opportunities for applying existing methods to emergency medical services for children, and identify potential career paths for current and future investigators.

Emergency medicine and public health: new steps in old directions

Emergency medicine and public health have opportunities to interact in at least 4 areas: surveillance of diseases, injuries, and health risks; monitoring health care access; delivering clinical preventive services; and developing policies to protect and improve the public's health. Recent, cross-cutting initiatives and innovations in these 4 areas follow pathways first explored more than a generation ago and provide an important impetus for future work. An analysis of recent contributions also points to various obstacles and challenges that must be addressed to take full advantage of existing and rapidly developing ties between emergency medicine and public health. The connections between these 2 fields will continue to create important partnership opportunities and the strong possibility of achieving new benefits for patients, the public, and the professionals who serve them.

Managed care and the pediatric emergency department

The growth of managed care has provided health benefits to millions of children while attempting to control the increase in health care costs. In adhering to these goals, MCOs are often at odds with emergency departments, and the emergency department physicians providing emergency care. The appropriateness or inappropriateness of emergency department visits can be disputed, but no criteria have been established. Even the definition of emergency is debated, although many states are adopting a prudent layperson standard. Emergency medicine physicians, primary care providers, and MCOs must cooperate to fully educate parents about the appropriate use of pediatric emergency services. Patients and MCOs should use facilities that can deliver pediatric emergency and critical care or provide appropriate transport systems to facilities that can. COBRA and EMTALA set the legal requirements to which emergency departments must comply when patients present for care. The basic caveats under COBRA require a medical screening examination for every patient and the stabilization of all patients with emergency medical conditions before inquiring about insurance or patients' ability to pay. A part of gatekeeping, MCOs often require authorization for treatment. MCOs authorize payment only. Evaluation and emergency treatment should not be withheld pending authorization. After the medical screening examination, recommended treatment should be in patients' best interests. All patients with potentially life-threatening conditions should be stabilized before transport, and all transfers must comply with the EMTALA. The transfer of unstable patients purely for economic reasons is a violation of the EMTALA. When stable, patients may be transferred to other facilities, but patients requiring specialty care should be taken to facilities best able to provide that care. Financial considerations should be superseded by medical necessity. Finally, improvements can be made in the way emergency medical service is provided to children within the current managed care system. The primary care provider is in a key position to inform parents about the types of pediatric emergencies, what to do in case one occurs, and to provide follow-up care. MCOs should incorporate clear information on pediatric emergencies. A mutual understanding of services needed, and how best to provide those services, are needed to forge a system that is responsive to children's emergency care needs.
