Insurance matters for low-income adults: results from a five-state survey

Using survey data from 2,000 low-income adult respondents in each of five states, this DataWatch assesses how uninsured, low-income adults differ from low-income adults who have public or private insurance and how Medicaid expansions have affected insurance coverage patterns across states with different eligibility policies. Findings show that the proportion of low-income uninsured adults is two to three times higher in states that have not expanded Medicaid eligibility beyond relatively low welfare levels. Compared with persons who have either Medicaid or private insurance, uninsured persons report more difficulties getting needed care, are less likely to have a regular provider, and rate the care they do receive as lower quality.

Racial differences in eligibility and enrollment in a smoking cessation clinical trial.

Objective: The purpose of this study was to compare the recruitment, eligibility screening, and enrollment of African American and White smokers into an intensive smoking cessation intervention trial [The Chicago STOP Smoking Trial (C-STOP)]. Methods: We compared demographic, smoking, substance use, and medical/psychiatric screening data from the recruitment records of 1,189 non-Hispanic, African American and White smokers screened for eligibility in the last year of a randomized pharmacological and behavioral smoking cessation trial. The study took place at a large urban medical center and two satellite locations within the Chicago metropolitan area. Results: Interest levels in the study were high among African American smokers, with twice as many African Americans as Whites contacting study staff for information and an initial screening. However, African Americans were nearly three times as likely not to be enrolled in the trial as Whites, because of higher ineligibility rates, failure to attend a screening session, and lower participation rates even among those meeting eligibility requirements. Conclusions: Racial differences were observed nearly at all levels of enrollment determination. These critical barriers to inclusion of African Americans in smoking cessation research limit our understanding of treatment efficacy and ultimately the ability to reduce the health disparities in tobacco-related disease experienced by African Americans.

Agreement between school study team decisions and authoritative definitions in classification of students at-risk for mild disabilities.

Investigated the degree to which school study teams (SSTs) considered and used results from traditional psychoeducational measures in determining eligibility or ineligibility for special education. Research definitions based on authoritative criteria were used to define 3 groups of students: 47 learning disabled students, 43 students with mild mental retardation, and 60 low achieving students. These groups were then compared to SST classification decisions to determine relative rates of agreement and disagreement. Results show that SSTs show relatively low rates of agreement with authoritative definitions of mild disability groups. Results also suggest that SSTs are making classification decisions based on perceived educational need rather than test scores provided by school psychologists, and the extent to which these scores meet arbitrary eligibility criteria.

Transcranial power mode Doppler duplex sonography of intracranial aneurysms

Recent events have challenged our health system to increase access to and provide high quality care for patients near the end of life. Simultaneously, Medicare is developing review policies to determine eligibility for hospice patients with select noncancer diagnoses. The purpose of this study was to determine whether the proposed policies met one of their chief goals: accurate identification of patients with a less-than-six-months prognosis. Only 35 percent of 104 patients who died within six months of admission to the hospice used for this study, LifePath Hospice, met the Medicare proposed criteria for hospice eligibility. The median and mean survival time of the sample was 14 and 30 days respectively. Based on this review, it is recommended that Medicare alter their proposed review policies and not limit access to hospice eligible patients who desire and are in need of such services.

On gender specificity of person characteristics in personnel advertisements: a study among future applications

This research is an examination of how person characteristics mentioned in personnel advertisements influence the judgments of male and female students with regard to their subjective eligibility for, and the attractiveness of, a particular vacancy. The first study showed that many frequently mentioned person characteristics in personnel advertisements applied differently to men and women, but that female characteristics were more in demand than male characteristics. The second study examined to what degree male and female participants felt that they themselves possessed male and female characteristics; results showed that the men were more confident about the degree to which they possessed male and female characteristics than the women were. The third study examined how the type of person characteristics mentioned in personnel advertisements influenced men's and women's judgments regarding their eligibility for and the attractiveness of a particular position. The men found all positions about equally attractive, whereas the women found "male" positions considerably less attractive. Implications of the study are discussed.
