The use of many services is lower in Medicare Advantage (MA) compared with traditional Medicare, generating cost savings for insurers, whereas the quality of ambulatory services is higher. This study examined the role of selective contracting with providers in achieving these outcomes, focusing on primary care physicians. Assessing primary care physician costliness based on the gap between observed and predicted costs for their traditional Medicare patients, we found that the average primary care physician in MA networks was $433 less costly per patient (2.

Background: Only a limited number of patients with major depressive disorder (MDD) respond to a first course of antidepressant medication (ADM). We investigated the feasibility of creating a baseline model to determine which of these would be among patients beginning ADM treatment in the US Veterans Health Administration (VHA).

Methods: A 2018-2020 national sample of = 660 VHA patients receiving ADM treatment for MDD completed an extensive baseline self-report assessment near the beginning of treatment and a 3-month self-report follow-up assessment.

Medicare Advantage (MA) enrollment growth could make it difficult for MA plans to maintain their track record of limiting discretionary utilization while delivering higher-quality care than traditional Medicare. We compared quality and utilization measures in Medicare Advantage and traditional Medicare in 2010 and 2017. Clinical quality performance was higher in MA health maintenance organizations (HMOs) and preferred provider organizations (PPOs) than in traditional Medicare for almost all measures in both years.

Background: Although research shows that more depressed patients respond to combined antidepressants (ADM) and psychotherapy than either alone, many patients do not respond even to combined treatment. A reliable prediction model for this could help treatment decision-making. We attempted to create such a model using machine learning methods among patients in the US Veterans Health Administration (VHA).

Racial inequities in clinical performance diminish overall health care system performance; however, quality assessments have rarely incorporated reliable measures of racial inequities. We studied care for more than one million Medicare fee-for-service beneficiaries with cancer to assess the feasibility of calculating reliable practice-level measures of racial inequities in chemotherapy-associated emergency department (ED) visits and hospitalizations. Specifically, we used hierarchical models to estimate adjusted practice-level Black-White differences in these events and described differences across practices.

Article Synopsis
  • The authors analyze various surveys and data to compare mental disorder rates before, during, and after the COVID-19 pandemic.
  • They found that the prevalence of clinically significant anxiety and depression increased by 30% to 50% during the pandemic, which is much lower than earlier exaggerated estimates of up to 800%.
  • Despite some fluctuations in prevalence throughout the pandemic, the overall relative prevalence of mental health issues did not change significantly over time.
