ACO Investment Model Produced Savings, But The Majority Of Participants Exited When Faced With Downside Risk.

Medicare's Accountable Care Organization (ACO) Investment Model (AIM) provided up-front funding to forty-one small, rurally located ACOs to encourage their participation in the Medicare Shared Savings Program. We estimate net savings to Medicare of $381.5 million over three years, driven by utilization reductions in inpatient and other institutional care and by the absence of shared risk for potential increases in Medicare spending incurred by participants.

Payer effects of personalized preventive care for patients with diabetes.

Objectives: To examine the effects of MD-Value in Prevention (MDVIP) enrollment on Medicare expenditures and utilization among fee-for-service (FFS) beneficiaries with diabetes over a 5-year period.

Study Design: We obtained participating physician and beneficiary enrollment lists from MDVIP and Medicare FFS claims data through the Virtual Research Data Center to compare changes in outcomes, before and after enrollment dates, with those of nonenrolled beneficiaries receiving primary care in the same local market.

Methods: We employed propensity score matching to identify comparison beneficiaries similar in observed characteristics and preenrollment trends.

Early Effects of an Accountable Care Organization Model for Underserved Areas.

Background: The Centers for Medicare and Medicaid Services (CMS) developed the Accountable Care Organization (ACO) Investment Model (AIM) to encourage the growth of Medicare Shared Savings Program (MSSP) ACOs in rural and underserved areas. AIM provides financial support to eligible MSSP ACOs by means of prepayment of shared savings. Estimation of the performance of AIM ACOs on measures of spending and utilization in their first performance year would be useful for understanding the viability of ACOs located in these areas.

Does adherence to the Loeb minimum criteria reduce antibiotic prescribing rates in nursing homes?

Objectives: The Loeb minimum criteria (LMC), developed by a 2001 consensus conference, are minimum standards for initiation of antibiotics in long term care settings, intended to reduce inappropriate prescribing. This study examined the relationship between nursing home prescriber adherence to the LMC and antibiotic prescribing rates, overall and for each of three specific conditions (urinary tract infections, respiratory infections, and skin and soft tissue infections).

Design: We performed a cross-sectional analysis at the resident-day level.
