Although Medicare provides beneficiaries with primary access to the health care system, racial/ethnic disparities in health care experiences and preventive care are well documented in the Medicare population.
To investigate disease burden and its possible impact on racial/ethnic health disparities for measures of secondary and tertiary access to health care, such as access to health plan information, obtaining recommended care in a timely manner, and immunization.
A total of 355,874 beneficiaries over the age of 64 years who responded to the 2008 Medicare Consumer Assessment of Healthcare Providers and Systems (CAHPS) survey.
We fit a series of linear, case-mix adjusted models predicting Medicare CAHPS measures of patient experience and immunization from race/ethnicity, a 0 to 6 count of disease burden, and their interaction.
Disparities between non-Hispanic whites and other racial/ethnic groups are largest among beneficiaries with no major health conditions. Disparities between whites and other racial/ethnic groups on getting care quickly and immunization are mitigated at higher levels of disease burden. Disparities persist at higher levels of disease burden for getting information from one's health plan.
Whites have better overall access to care than other beneficiaries with Medicare in the absence of major health conditions. Disparities in getting care quickly and immunizations are smaller among beneficiaries with greater disease burden, perhaps as a function of integration into the health care system gained through management of health issues. These results underscore the importance of outreach to minorities with low utilization and few or no major health conditions.
[Show abstract][Hide abstract] ABSTRACT: Poorly-executed transitions out of the hospital contribute significant costs to the healthcare system. Several evidence-based interventions can reduce post-discharge utilization.
To evaluate the cost avoidance associated with implementation of the Care Transitions Intervention (CTI).
A quasi-experimental cohort study using consecutive convenience sampling.
Fee-for-service Medicare beneficiaries hospitalized from 1 January 2009 to 31 May 2011 in six Rhode Island hospitals.
The CTI is a patient-centered coaching intervention to empower individuals to better manage their health. It begins in-hospital and continues for 30 days, including one home visit and one to two phone calls.
We examined post-discharge total utilization and costs for patients who received coaching (intervention group), who declined or were lost to follow-up (internal control group), and who were eligible, but not approached (external control group), using propensity score matching to control for baseline differences.
Compared to matched internal controls (N = 321), the intervention group had significantly lower utilization in the 6 months after discharge and lower mean total health care costs ($14,729 vs. $18,779, P = 0.03). The cost avoided per patient receiving the intervention was $3,752, compared to internal controls. Results for the external control group were similar. Shifting of costs to other utilization types was not observed.
This analysis demonstrates that the CTI generates meaningful cost avoidance for at least 6 months post-hospitalization, and also provides useful metrics to evaluate the impact and cost avoidance of hospital readmission reduction programs.

[Show abstract][Hide abstract] ABSTRACT: African Americans face higher risk of AKI than Caucasians. The extent to which this increased risk is because of differences in clinical, socioeconomic, or genetic risk factors is unknown. We evaluated 10,588 African-American and Caucasian participants in the Atherosclerosis Risk in Communities study, a community-based prospective cohort of middle-aged individuals. Participants were followed from baseline study visit (1996-1999) to first hospitalization for AKI (defined by billing code), ESRD, death, or December 31, 2010. African-American participants were slightly younger (61.7 versus 63.1 years, P<0.001), were more often women (64.5% versus 53.2%, P<0.001), and had higher baseline eGFR compared with Caucasians. Annual family income, education level, and prevalence of health insurance were lower among African Americans than Caucasians. The unadjusted incidence of hospitalized AKI was 7.4 cases per 1000 person-years among African Americans and 5.8 cases per 1000 person-years among Caucasians (P=0.002). The elevated risk of AKI among African Americans persisted after adjustment for demographics, cardiovascular risk factors, kidney markers, and time-varying number of hospitalizations (adjusted hazard ratio, 1.20; 95% confidence interval [95% CI], 1.01 to 1.43; P=0.04); however, accounting for differences in income and/or insurance by race attenuated the association (P>0.05). High-risk APOL1 variants did not associate with AKI among African Americans (demographic-adjusted hazard ratio, 1.07; 95% CI, 0.69 to 1.65; P=0.77). In summary, the higher risk of AKI among African Americans may be related to disparities in socioeconomic status.
