We compare cancer screening rates between the United States and Europe. Many European countries have organized screening programs, whereas the U.S. approach is relatively decentralized. Many European countries, unlike the United States, also impose upper age limits on screening. Overall, European screening rates were 22-88 percent of the corresponding U.S. rates. U.S. residents are more likely to be screened at younger ages, when the expected benefit from early detection is the greatest, but also at older ages, when the expected benefit is declining.

    • "Response categories include a range of 1–5 years, ''more than 5 years,'' and ''never.'' The proportion of women screened calculated using MEPS closely matches the proportion calculated from the Health and Retirement Study but is higher than the proportion calculated using insurance claims[14]. Using the 2011 MEPS, we calculated the proportion of women aged 40–64 who were uninsured for the entire year, lived in households with incomes below 250 % of the federal poverty level, and reported having received a mammogram in the past 2 years.

    ABSTRACT: Objective To describe the number and proportion of eligible women receiving mammograms funded by the National Breast and Cervical Cancer Early Detection Program (NBCCEDP). Methods Low-income, uninsured, and underinsured women aged 40–64 are eligible for mammography screening through the NBCCEDP. We used data from the NBCCEDP, the Current Population Survey, and Medical Expenditure Panel Survey to describe the number and proportion of women screened by the NBCCEDP and overall. Results In 2011 and 2012, the NBCCEDP screened 549,043 women aged 40–64, an estimated 10.6 % (90 % confidence interval [CI] 10.4–10.9 %) of the eligible population. We estimate that 30.6 % (90 % CI 26.4–34.8 %) of eligible women aged 40–64 were screened outside the NBCCEDP, and 58.8 % (90 % CI 54.6–63.0 %) were not screened. The proportion of eligible women screened by the NBCCEDP varied across states, with an estimated range of 3.2 % (90 % CI 2.9–3.5 %) to 52.8 % (90 % CI 36.1–69.6 %) and a median of 13.7 % (90 % CI 11.0–16.4 %). The estimated proportion of eligible women aged 40–64 who received mammograms through the NBCCEDP was relatively constant over time, 11.1 % (90 % CI 10.2–11.9 %) in 1998–1999 and 10.6 % (90 % CI 10.4–11.9 %) in 2011–2012 (p = 0.23), even as the number of women screened increased from 343,692 to 549,043. Conclusions Although the NBCCEDP provided screening services to over a half million low-income uninsured women for mammography, it served a small percentage of those eligible. The majority of low-income, uninsured women were not screened.

    • "As we demonstrate later, these differences are unlikely to be explained by differences in diagnosis or reporting. For example, the prevalence of stroke—a condition that rarely goes undiagnosed—is twice as low in Europe as in the U.S. On the other hand, the prevalence of cancer may be higher in the U.S. because of higher screening rates (Howard et al., 2009).

    ABSTRACT: In 1975, 50-year-old Americans could expect to live slightly longer than most of their Western European counterparts. By 2005, American life expectancy had fallen behind that of most Western European countries. We find that this growing longevity gap is primarily due to real declines in the health of near-elderly Americans, relative to their Western European peers. We use a microsimulation approach to project what US longevity would look like, if US health trends approximated those in Western Europe. The model implies that differences in health can explain most of the growing gap in remaining life expectancy. In addition, we quantify the public finance consequences of this deterioration in health. The model predicts that gradually moving American cohorts to the health status enjoyed by Western Europeans could save up to $1.1 trillion in discounted total health expenditures from 2004 to 2050.

    ABSTRACT: Epoetin alfa and darbepoetin alfa are erythropoiesis-stimulating agents (ESAs) indicated for the treatment of anemia in chronic renal failure, including patients on dialysis and patients not on dialysis. Clinical experience demonstrates that the dose conversion ratio (DCR) between epoetin alfa and darbepoetin alfa is nonproportional across the dosing spectrum. However, previous calculations of the dose relationship between epoetin alfa and darbepoetin alfa, described in previous work as the "dose ratio" (DR), (a) used cross-sectional designs (i.e., compared mean doses for patient groups using each ESA) and were therefore vulnerable to confounding or (b) did not adjust for the nonproportional dose relationship. DRs reported in the literature range from 217:1 to 287:1 epoetin alfa (Units [U]):darbepoetin alfa (micrograms [micrograms]). Payers may need a single DCR that accounts for the nonproportional dose relationship to evaluate the economic implications of converting a nondialyzed patient population with chronic kidney disease (CKD) from epoetin alfa to darbepoetin alfa. To estimate a single mean maintenance DCR between epoetin alfa and darbepoetin alfa in subjects with CKD not receiving dialysis, using methods that take into account the nonproportional dose relationship between the 2 ESAs. This was a post-hoc analysis of a subset of patients enrolled in an unpublished, open-label, single arm phase 3 clinical trial (ClinTrial. gov identifier NCT00093977) that was completed in 2006. Although the clinical trial enrolled both dialyzed and nondialyzed patients, the present study used a patient subset comprising nondialyzed patients with CKD previously receiving weekly or every-other-week (Q2W) epoetin alfa who were switched to Q2W darbepoetin alfa to maintain hemoglobin (Hb) levels between 11.0 and 13.0 grams per deciliter. A population mean DCR was estimated using 2 methods: (a) a regression-based method in which the log-transformed (natural logarithm) mean weekly darbepoetin alfa dose over the evaluation period of the study (weeks 25 to 33) was regressed on the log-transformed (natural logarithm) weekly epoetin alfa dose over the 2-week screening period; and (b) a mean ratio method in which the DCR was calculated for each individual patient and then averaged for the study population to give a population-level DCR. Sensitivity analyses estimated the DCR in various subgroups. Of 1,127 patients enrolled in clinical trial NCT00093977, 567 patients on dialysis were excluded. Of the remaining 560 patients, 104 received weekly or Q2W epoetin alfa, were switched to Q2W darbepoetin alfa, received at least 1 non-zero dose of darbepoetin alfa during the evaluation period, and were included in the DCR calculation for the present study. Analysis of the log-log plot for the regression-based method indicated 2 or more possible regression lines with separate slopes. However, based on our a priori analysis plan to estimate a single DCR for the patient sample, the estimated sample mean maintenance DCR in the regression analysis was 330.6 U epoetin alfa to 1 micrograms darbepoetin alfa. In the mean ratio analysis, the DCR was 375.6 U:1 micrograms. Sensitivity analyses in which DCRs were calculated for different subgroups with different baseline differences identified a variable DCR range of 302-380 U:1 micrograms. The methodology used in estimating the DCR accounts for the nonproportional dose relationship between epoetin alfa and darbepoetin alfa and may represent an advance over the methods used in previous research. The mean maintenance DCR between the 2 ESAs exceeds a threshold of 300 U:1 micrograms, which is greater than previously reported DRs. This methodology provides payers the means to compare ESA doses in CKD patients not receiving dialysis.
