Preventive services among Medicare beneficiaries with supplemental coverage versus HMO enrollees, medicaid recipients, and elders with no additional coverage.

BACKGROUND: Studies conducted when Medicare began to cover preventive services, found that beneficiaries with supplemental insurance were much more likely to have such services than those without additional coverage. OBJECTIVE: To examine preventive services among Medicare beneficiaries with supplemental insurance, Medicaid, health maintenance organization (HMO) enrollees, and those without additional insurance. RESEARCH DESIGN: Analysis of the 1996 Medical Expenditure Panel Survey, a nationally representative multistage survey. SUBJECTS: 2,251 persons aged 65 and older with Medicare coverage. MEASURES: Self-reported preventive services, specifically, blood pressure measurement, cholesterol testing, influenza vaccination, mammography, Papanicolau (Pap) testing, and breast and prostate examinations. Multivariate modeling was used to adjust for age, education, race/ethnicity, and functional status. RESULTS: Elders without additional coverage were approximately 10% points less likely to have influenza vaccination, cholesterol testing, mammography, or Pap smears than those with supplemental coverage (P < 0.05). Multivariate adjustment attenuated some of these differences with age and education being the most important predictors of having preventive services. HMO enrollees were more likely to have mammograms than those with supplemental coverage (P < 0.05). CONCLUSIONS: Several years after Medicare extended coverage to include preventive services, differences in utilization of such services among elders with and without supplemental insurance have narrowed substantially.

Differences in functional status of Hispanic versus non-Hispanic White elders: data from the Medical Expenditure Panel Survey.

OBJECTIVES: Few national studies have focused specifically on the functional status of Hispanic elders. We examined the prevalence of functional limitations and disabilities among Hispanic and Black elders compared to non-Hispanic Whites. METHODS: We analyzed seven measures of functional limitations, disabilities, and dependencies. Logistic regression was used to examine racial and ethnic group differences adjusting for age, gender, and education. RESULTS: Compared to non-Hispanic Whites, Hispanics tended to report greater instrumental activities of daily living (IADL) dependencies and cognitive disabilities. Blacks were more likely to have activities of daily living (ADL) and IADL dependencies and require use of assistive devices compared to non-Hispanic Whites. Further adjustment for respondent status reduced differences between groups, but these models may overadjust for functional status differences. DISCUSSION: Given the projected growth of minority elders, policymakers and planners will need to consider race and ethnic differentials in functional status in determining future medical and social service needs.

Health insurance coverage of immigrants living in the United States: differences by citizenship status and country of origin.

OBJECTIVES: This study examined health insurance coverage among immigrants who are not US citizens and among individuals from the 16 countries with the largest number of immigrants living in the United States. METHODS: We analyzed data from the 1998 Current Population Survey, using logistic regression to standardize rates of employer-sponsored coverage by country of origin. RESULTS: In 1997, 16.7 million immigrants were not US citizens. Among non-citizens, 43% of children and 12% of elders lacked health insurance, compared with 14% of non-immigrant children and 1% of non-immigrant elders. Approximately 50% of non-citizen full-time workers had employer-sponsored coverage, compared with 81% of non-immigrant full-time workers. Immigrants from Guatemala, Mexico, El Salvador, Haiti, Korea, and Vietnam were the most likely to be uninsured. Among immigrants who worked full-time, sociodemographic and employment characteristics accounted for most of the variation in employer health insurance. For Central American immigrants, legal status may play a role in high un-insurance rates. CONCLUSIONS: Immigrants who are not US citizens are much less likely to receive employer-sponsored health insurance or government coverage; 44% are uninsured. Ongoing debates on health insurance reform and efforts to improve coverage will need to focus attention on this group.

Trends in health insurance coverage, 1989-1997.

The authors analyze trends in health insurance coverage in the United States from 1989 through 1997, using cross-sectional surveys by the U.S. Census Bureau (Current Population Survey) of 160,000 persons representative of the non-institutionalized population. Between 1989 and 1997, the number of people without health insurance increased by 10.1 million to 43.4 million. From 1989 to 1993, the proportion covered by Medicaid increased by 3.6 percentage points while the proportion covered by private insurance declined by 4.2 percentage points. Since then, private coverage rates have stabilized and Medicaid coverage has decreased. Consequently, the number and percent uninsured continues to rise. Young adults age 18-39 had the largest increase in the proportion uninsured, and rates among children have also risen steeply since 1992. While blacks had the largest increase in the percent uninsured, Hispanics accounted for 35.6 percent of the increase in the number uninsured. Low-income families constituted over half of the increase in the number uninsured, but since 1993 the middle income group had the largest increase in the percent uninsured. Northeastern states had the largest increase in the percent uninsured. Thus, despite economic prosperity, the numbers and rates of the uninsured continue to rise. Principally affected are children and young adults, poor and middle-income families, blacks, and Hispanics.

Impact of language barriers on patient satisfaction in an emergency department.

OBJECTIVE: To examine patient satisfaction and willingness to return to an emergency department (ED) among non-English speakers. DESIGN: Cross-sectional survey and follow-up interviews 10 days after ED visit. SETTING: Five urban teaching hospital EDs in the Northeastern United States. PATIENTS: We surveyed 2,333 patients who presented to the ED with one of six chief complaints. MEASUREMENTS AND MAIN RESULTS: Patient satisfaction, willingness to return to the same ED if emergency care was needed, and patient-reported problems with care were measured. Three hundred fifty-four (15%) of the patients reported English was not their primary language. Using an overall measure of patient satisfaction, only 52% of non-English-speaking patients were satisfied as compared with 71% of English speakers (p < .01). Among non-English speakers, 14% said they would not return to the same ED if they had another problem requiring emergency care as compared with 9.5% of English speakers (p < .05). In multivariate analysis adjusting for hospital site, age, gender, race/ethnicity, education, income, chief complaint, urgency, insurance status, Medicaid status, ED as the patient's principal source of care, and presence of a regular provider of care, non-English speakers were significantly less likely to be satisfied (odds ratio [OR] 0.59; 95% confidence interval [CI] 0.39, 0.90) and significantly less willing to return to the same ED (OR 0.57; 95% CI 0.34, 0.95). Non-English speakers also were significantly more likely to report overall problems with care (OR 1.70; 95% CI 1.05, 2.74), communication (OR 1.71; 95% CI 1.18, 2.47), and testing (OR 1.77; 95% CI 1.19, 2.64). CONCLUSIONS: Non-English speakers were less satisfied with their care in the ED, less willing to return to the same ED if they had a problem they felt required emergency care, and reported more problems with emergency care. Strategies to improve satisfaction among this group of patients may include appropriate use of professional interpreters and increasing the language concordance between patients and providers.

Going bare: trends in health insurance coverage, 1989 through 1996.

OBJECTIVES: This study analyzed trends in health insurance coverage in the United States from 1989 through 1996. METHODS: Data from annual cross-sectional surveys by the US Census Bureau were analyzed. RESULTS: Between 1989 and 1996, the number of uninsured persons increased by 8.3 million (90% confidence interval [CI] = 7.7, 8.9 million). In 1996, 41.7 million (90% CI = 40.9, 42.5 million) lacked insurance. From 1989 to 1993, the proportion with Medicaid increased by 3.6 percentage points (90% CI = 3.1, 4.0), while the proportion with private insurance declined by 4.2 percentage points (90% CI = 3.7, 4.7). From 1993 to 1996 private coverage rates stabilized but did not reverse earlier declines. Consequently, the number uninsured continued to increase. The greatest increase in the population of uninsured [corrected] was among young adults aged 18 to 39 years; rates among children also rose steeply after 1992. While Blacks had the largest percentage increase, Hispanics accounted for 36.4% (90% CI = 32.3%, 40.5%) of the increase in the number uninsured. From 1989 to 1993, the majority of the increase was among poor families. Since then, middle-income families have incurred the largest increase. Northcentral and northeastern states had the largest increases in percent uninsured. CONCLUSIONS: Despite economic prosperity, the numbers and rates of the uninsured continued to rise. Principally affected were children and young adults, poor and middle income families, blacks, and Hispanics.

A reappraisal of private employers' role in providing health insurance.

BACKGROUND: In 1996, according to official figures, 61 percent of Americans received health insurance through employers. However, this estimate includes persons who relied primarily on government insurance such as Medicare, workers whose employers arranged their insurance but contributed nothing toward the premiums, and government employees whose private coverage was paid for by taxpayers. METHODS: To estimate the number of persons whose principal health insurance was paid for in whole or in part by employers in the private sector and the number receiving government-funded insurance, we analyzed data from the March 1997 Current Population Survey. Approximately 130,000 persons representative of the noninstitutionalized U.S. population were sampled. We considered people to be covered principally by health insurance paid for by private-sector employers if they had no public insurance coverage and were covered by insurance from a non-governmental employer who paid all or part of their premiums. Those who were covered by Medicaid, Medicare, insurance resulting from former or current military service, or the Indian Health Service were considered to be receiving government insurance. RESULTS: In 1996, 43.1 percent of the population (90 percent confidence interval, 42.7 to 43.5 percent) depended principally on health insurance paid for by private-sector employers, 34.2 percent (90 percent confidence interval, 33.8 to 34.6 percent) had publicly funded insurance, 7.1 percent (90 percent confidence interval, 6.8 to 7.6 percent) purchased their own coverage, and 15.6 percent (90 percent confidence interval, 15.3 to 15.9 percent) were uninsured. In only six states was more than half the population covered principally by health insurance paid for by private-sector employers. CONCLUSIONS: Current definitions of health insurance overemphasize the role of private employers and underestimate the extent to which government pays for health insurance.

Prognostic factors in patients with methanol poisoning.

OBJECTIVE: To identify prognostic factors in methanol poisoning and determine the effect of medical interventions on clinical outcome. METHODS: Retrospective review of all patients treated for methanol poisoning from 1982 through 1992 at The Toronto Hospital. Presenting history, physical examination, results of laboratory tests, medical interventions, and final outcomes after hemodialysis were abstracted. RESULTS: Of 50 patients treated for methanol poisoning, 18 (36%) died, 32 (64%) survived. Seven of the 32 survivors sustained visual sequelae (22%), the remaining 25 (78%) recovered completely. Patients presenting with coma or seizure had 84% (16/19) mortality compared to 6% (2/31) in those without (p < 0.001). Initial arterial pH < 7 was also associated with significantly higher mortality (17/19, 89% vs 1/31, 3%, p < 0.001). There were no differences in time from presentation to dialysis between survivors and fatalities (8.4 +/- 3.6 vs 7.6 +/- 3.5 hours, p = 0.47). The deceased patients had higher mean methanol concentration than the survivors (83 +/- 53 vs 41 +/- 25 mmol/L, p = 0.004). Subgroup analysis of 19 patients presenting with visual symptoms who survived showed prolonged acidosis (5.4 +/- 2.3 vs 3.0 +/- 2.1 hours, p = 0.06) in those with persistent visual sequelae. CONCLUSIONS: Coma or seizure on presentation and severe metabolic acidosis, in particular initial arterial pH < 7, are poor prognostic indicators in methanol poisoning. Survivors presented with lower methanol concentrations. Patients with residual visual sequelae had more prolonged acidosis than those with complete recovery. Future studies will be needed to confirm the effect of correction of acidosis on final clinical outcome.

Can Medicaid managed care provide continuity of care to new Medicaid enrollees? An analysis of tenure on Medicaid.

OBJECTIVES: The purpose of this study was to analyze duration of coverage among new Medicaid enrollees. METHODS: The 1991 Survey of Income and Program Participation was used to examined the duration of coverage for individuals who did not have Medicaid in January 1991 and obtained coverage by May 1993. RESULTS: Of new Medicaid enrollees, 38% (90% confidence interval [CI] = 34%, 42%) remained covered 1 year later; 26% (90% CI = 21%, 31%) remained covered at 28 months. Of those older than 65 years, 54% (90% CI = 31%, 77%) retained Medicaid for 28 months, vs 20% (90% CI = 14%, 26%) of children. Of people who lost Medicaid, 54% (90% CI = 31%, 77%) had no insurance the following month. CONCLUSIONS: Almost two thirds of new Medicaid recipients lose coverage within 12 months. It is unlikely that Medicaid managed care will enhance continuity of care for new recipients.
