Eager to reduce unnecessary use of hospital emergency departments by Medicaid enrollees, states are increasingly implementing cost sharing for nonemergency visits. This paper uses monthly data from the 2001-2006 Medical Expenditure Panel Surveys (MEPS) to examine how changes in nine states' copayment policies influence enrollees' use of emergency departments. The results suggest that requiring copayments for nonemergency visits did not decrease emergency department use by Medicaid enrollees. Future research should examine more closely the effects at the state level and investigate whether these copayments affected the use of other services, such as hospitalizations or visits to physicians by Medicaid enrollees.

    • "If this large and growing population of older adults is in fact insensitive to using the ED relative to primary care, then their demand for the ED will continue to increase. Perhaps future research efforts could examine how altering deductible and co-payment obligations might affect service use patterns so that those who persistently present with non-severe conditions become more sensitive about using the ED when community-based alternatives are available [12,40].

    ABSTRACT: It is well known that older adults figure prominently in the use of emergency departments (ED) across the United States. Previous research has differentiated ED visits by levels of clinical severity and found health status and other individual characteristics distinguished severe from non-severe visits. In this research, we classified older adults into population groups that persistently present with severe, non-severe, or indeterminate patterns of ED episodes. We then contrasted the three groups using a comprehensive set of covariates. Using a unique dataset linking individual characteristics with Medicare claims for calendar years 1991-2007, we identified patterns of ED use among the large, nationally representative AHEAD sample consisting of 5,510 older adults. We then classified one group of older adults who persistently presented to the ED with clinically severe episodes and another group who persistently presented to the ED with non-severe episodes. These two groups were contrasted using logistic regression, and then contrasted against a third group with a persistent pattern of ED episodes with indeterminate levels of severity using multinomial logistic regression. Variable selection was based on Andersen's behavioral model of health services use and featured clinical status, demographic and socioeconomic characteristics, health behaviors, health service use patterns, local health care supply, and other contextual effects. We identified 948 individuals (17.2% of the entire sample) who presented a pattern in which their ED episodes were typically defined as severe and 1,076 individuals (19.5%) who typically presented with non-severe episodes. Individuals who persistently presented to the ED with severe episodes were more likely to be older (AOR 1.52), men (AOR 1.28), current smokers (AOR 1.60), experience diabetes (AOR (AOR 1.80), heart disease (AOR 1.70), hypertension (AOR 1.32) and have a greater amount of morbidity (AOR 1.48) than those who persistently presented to the ED with non-severe episodes. When contrasted with 1,177 individuals with a persistent pattern of indeterminate severity ED use, persons with severe patterns were older (AOR 1.36), more likely to be obese (AOR 1.36), and experience heart disease (AOR 1.49) and hypertension (AOR 1.36) while persons with non-severe patterns were less likely to smoke (AOR 0.63) and have diabetes (AOR 0.67) or lung disease (AOR 0.58). We distinguished three large, readily identifiable groups of older adults which figure prominently in the use of EDs across the United States. Our results suggest that one group affects the general capacity of the ED to provide care as they persistently present with severe episodes requiring urgent staff attention and greater resource allocation. Another group persistently presents with non-severe episodes and creates a considerable share of the excess demand for ED care. Future research should determine how chronic disease management programs and varied co-payment obligations might impact the use of the ED by these two large and distinct groups of older adults with consistent ED use patterns.

    ABSTRACT: In 2006, Idaho and Kentucky became two of the first states to implement changes to their Medicaid programs under authority granted by the 2005 Deficit Reduction Act (DRA). The DRA granted new flexibility in the design of state Medicaid programs, including a state plan amendment (SPA) option for changes that previously would have required a waiver. This paper uses state Medicaid administrative data to analyze the impact of Medicaid policy changes implemented in these states through a series of SPAs in 2006 and 2007. Changes in utilization are examined for multiple services, including physician, dental, and ER visits, inpatient stays, and prescriptions, among non-elderly adult Medicaid recipients following changes in cost sharing, reimbursement, service delivery, and covered services. Where possible, enrollees not affected by the changes served as a comparison group. While relatively few adults in Idaho received a wellness exam after such coverage was added, the adoption of managed care for dental services was associated with increased receipt of dental care, including preventive care. The new limits on brand name prescriptions in Kentucky were associated with a reduction in the proportion of enrollees with two or more monthly name brand prescriptions while the small copayments introduced did not appear to have a dramatic impact. We find that changes in financial incentives on both the supply-side (such as reimbursement increases) and the demand-side (i.e., benefit changes) alone may not be enough to generate the desired levels of preventive care, especially among those with chronic health conditions.

    ABSTRACT: Although most Medicaid programs have some coverage for tobacco-cessation treatments, little is known about how well the covered treatments are utilized among Medicaid enrollees. To examine the impact of Arkansas Medicaid coverage of tobacco-cessation treatment on utilization of FDA-approved tobacco-cessation pharmacotherapies and counseling services by Medicaid enrollees. This study used Arkansas Medicaid administrative claims data from October 1, 2003, to June 30, 2008. Trend changes in the following monthly measures were examined: (1) total number of pharmacy claims for each covered pharmacotherapy; (2) total number of medical claims for counseling services; and (3) total number of unique enrollees who received each type of covered tobacco-cessation treatment. Average unit of defined daily dose and days with treatment stratified by tobacco-cessation products within 180 days after the first tobacco-cessation treatment were examined for intensity of treatment. Data collection was finished in 2009 and analysis was completed in 2011. By June 30, 2008, a total of 12,673 enrollees received some tobacco-cessation treatments, and 77% of them received pharmacotherapies only. Implementation of the coverage expansion generated an initial increase in utilization of tobacco-cessation medications but quickly declined after 3 months. Utilization increased again when varenicline was added, but also decreased sharply after 6 months. Patterns of monthly claims for counseling services appeared to be inconsistent with the policy change. Medicaid coverage alone may have limited sustained effect on increasing utilization of the covered tobacco-cessation treatments among Medicaid enrollees.
