Timing of home health care initiation and 30-day rehospitalizations among Medicare beneficiaries with diabetes by race and ethnicity.
Older adults with diabetes are at elevated risk of complications following hospitalization. Home health care services mitigate the risk of adverse events and facilitate a safe transition home. In the United States, when home health care services are prescribed, federal guidelines require they begin within two days of hospital discharge. This study examined the association between timing of home health care initiation and 30-day rehospitalization outcomes in a cohort of 786,734 Medicare beneficiaries following a diabetes-related index hospitalization admission during 2015.

Comparison of diabetes medications used by adults with commercial insurance vs Medicare Advantage, 2016 to 2019.
Investigators sought to compare trends in initiation of treatment with GLP-1RA, SGLT2i, and DPP-4i by older adults with type 2 diabetes insured by Medicare Advantage vs commercial health plans. They found that Medicare Advantage beneficiaries may be less likely than commercially insured beneficiaries to be treated with newer medications to lower glucose levels, with greater disparities among lower-income patients. They recommended further investigation of nonclinical factors contributing to treatment decisions and efforts to promote greater equity in diabetes management.

Prescriber continuity and medication availability in older adults with cardiometabolic conditions.
Researchers examined whether the number of prescribers of essential medications was associated with the availability of medications, a surrogate for adherence, to manage diabetes, hypertension or dyslipidemia. They found that the number of prescribers was not significantly associated with availability of oral diabetes agents but having more prescribers is associated with increased medication availability in older Medicare beneficiaries with dyslipidemia or hypertension.

Adherence to tyrosine kinase inhibitors among Medicare Part D beneficiaries with chronic myeloid leukemia.
The authors of this study identified 836 patients with chronic myeloid leukemia (CML) with Medicare Part D insurance coverage who were new tyrosine kinase inhibitors (TKI) users and examined treatment nonadherence. They indicted that the current population-based study found a significantly higher rate of nonadherence among heavily subsidized patients with substantially lower out-of-pocket costs, which suggested that future research is needed to help lower the nonadherence rate among these individuals.

Trends in opioid prescriptions among Part D Medicare recipients From 2007 to 2012.
The researchers used national Medicare data from 2007-2012 to assess temporal and geographic trends in rates of opioid prescription and relationship to opioid toxicity and different state regulations in Part D Medicare recipients. Their analyses of the Medicare data demonstrated substantial growth in opioid prescriptions from 2007 to 2011 and large variation in opioid prescriptions across states.
