Medicare Part D is Associated With Reducing the Financial Burden of Health Care Services in Medicare Beneficiaries With Diagnosed Diabetes
BACKGROUND: Medicare Part D, implemented in 2006, provided coverage for prescription drugs to all Medicare beneficiaries. OBJECTIVE: To examine the effect of Part D on the financial burden of persons with diagnosed diabetes. RESEARCH DESIGN, SUBJECTS, AND OUTCOME MEASURES: We conducted an interrupted time-series analysis using data from the 1996 to 2008 Medical Expenditure Panel Survey (11,178 persons with diabetes who were covered by Medicare, a…
Socioeconomic Factors and Persistent Racial Disparities in Childhood Vaccination
Differential Effects of the DTaP and MMR Vaccine Shortages on Timeliness of Childhood Vaccination Coverage
Objectives. We determined the effect of diphtheria and tetanus toxoids and acellular pertussis vaccine (DTaP) and measles, mumps, rubella (MMR) vaccine shortages on timeliness of the third dose of DTaP (DTaP3), the fourth dose of DTaP (DTaP4), and the first dose of MMR (MMR1) among subgroups of preschool children. Methods. Data from the 2001 and 2002 National Immunization Surveys were analyzed. Children age-eligible to receive DTaP3, DTaP4, or MM…
Timeliness of Childhood Immunizations: A State-Specific Analysis
Objective. We examined the timeliness of vaccine administration among children aged 24 to 35 months for each state of the United States and the District of Columbia. Methods. We analyzed the timeliness of vaccinations in the 2000–2002 National Immunization Survey. We used a modified Bonferroni adjustment to compare a reference state with all other states. Results. Receipt of all vaccinations as recommended ranged from 2% (Mississippi) to 26% (Mas…
Children Who Have Received No Vaccines: Who Are They and Where Do They Live?
Context. Each year 2.1 million children 19 to 35 months of age are undervaccinated. Among these are children who have received no vaccinations. Unvaccinated children are at increased risk of acquiring and transmitting vaccine-preventable diseases. Objectives. To assess whether the characteristics of children with no vaccinations differ from those of undervaccinated children, to monitor trends in the numbers of unvaccinated children, and to identi…
Racial/Ethnic Disparities in Preschool Immunizations: United States, 1996–2001
Objectives. We examined current racial/ethnic differences in immunization coverage rates among US preschool children. Methods. Using National Immunization Survey data from 1996 through 2001, we compared vaccination coverage rates between non-Hispanic White, non-Hispanic Black, Hispanic, and Asian preschool children. Results. During the 6-year study period, the immunization coverage gap between White and Black children widened by an average of 1.1…
Disparities in Immunizations
Our analysis published in this issue of the Journal1 predicts that disparities in vaccination coverage between non-Hispanic Whites and both non-Hispanic Blacks and Hispanics will widen, and the gap between non-Hispanic Whites and Asians will narrow. That analysis is based on 6 years of data (1996–2001) from the National Immunization Survey (NIS). Since then, 2002 NIS data have become available. We used these data to reanalyze and update our analy…
Vaccination Coverage of American Indian/Alaska Native Children Aged 19 to 35 Months: Findings From the National Immunization Survey, 1998–2000
The federal government has placed a priority on eliminating racial and ethnic health disparities, such as disparities in vaccination coverage, by 2010.1 This study was conducted to examine recent vaccine coverage rates for American Indian/Alaska Native (AIAN) children aged 19 to 35 months and to compare these rates with those of non-AIAN children
