Social risk adjustment In the hospital readmissions reduction program: a systematic review and implications for policy.
Investigators reviewed fourteen studies of social risk adjustment in Medicare's Hospital Readmissions Reduction Program (HRRP). They concluded that their findings support the use of social risk adjustment to improve provider payment equity and highlight opportunities to enhance social risk adjustment in value-based payment programs.

Estimating heterogeneous effects of a policy intervention across organizations when organization affiliation is missing for the control group: application to the evaluation of accountable care organizations.
This study looked at the effects of accountable care organizations (ACOs) on lowering health care costs and reducing the rate of hospital readmissions. The authors used Medicare fee-for-service claims data from 2009-2014 to estimate the heterogenous effects of Medicare ACO programs on hospital admissions across hospital referral regions and provider groups. The results suggested that the ACO programs reduced the rate of readmission to hospitals, and that the effect of joining an ACO varied considerably across medical groups.

Does a reduction in readmissions result in net savings for most hospitals? An examination of Medicare's hospital readmissions reduction program.
This study aimed (1) to estimate the impact of an incremental reduction in excess readmissions on a hospital's Medicare reimbursement revenue, for hospitals subject to penalties under the Medicare's Hospital Readmissions Reduction Program and (2) to evaluate the economic case for an investment in a readmission reduction program.

Trends in hospital readmission of Medicare-covered patients with heart failure.
This study sought to compare trends in Medicare risk-adjusted, 30-day readmissions following principal heart failure (HF) hospitalizations and other hospitalizations with HF. The investigators found that patients with HF are often hospitalized for other causes, and these hospitalizations have high readmission rates. Policy changes led to decreases in readmission rates for both principal and secondary HF hospitalizations. Readmission rates in both groups remained high, suggesting that initiatives targeting all hospitalized patients with HF continue to be warranted.

Trends in 30-day readmission rates for Medicare and non-Medicare patients in the era of the Affordable Care Act.
In this study the investigators we assessed trends in all-cause readmission rates for 1 of the 3 HRRP conditions or conditions not targeted by the HRRP in age-insurance groups defined by age group (>/=65 years or <65 years) and payer (Medicare, Medicaid, or private insurance). The investigators concluded that there appeared to be a systematic improvement in readmission rates for patient groups beyond the population of fee-for-service, older, Medicare beneficiaries included in the HRRP.

Association of coded severity with readmission reduction after the hospital readmissions reduction program.
This research letter describes a study which examined coding by hospitals used to determine rates of readmission under the Hospital Readmission Reduction Program (HRRP). Hospitals who go above a certain rate are subject to financial penalties for 3 targed medical conditions. It was determined that hospitals have begun to change their coding to show increased severity of illness in many of those readmissions. Data came from discharges from the Medicare Provider Analysis and review file between 2008 and 2014. Researchers compared coding severity levels from before HRRP was implemented and post April 1, 2010 when it began.

Hemodialysis hospitalizations and readmissions: the effects of payment reform.
The researchers used a retrospective cohort interrupted time-series study design to examine whether the 2004 nephrologist reimbursement reform led to reduced hospitalizations and rehospitalizations. They found no significant change in all-cause hospitalization or rehospitalization and slight reductions in fluid overload hospitalization and rehospitalization following reimbursement reform.

The effects of state psychiatric hospital waitlist policies on length of stay and time to readmission.
This study examined the effects of a waitlist policy for state psychiatric hospitals on length of stay and time to readmission. The authors found that waitlists were associated with increased length of stay and time to readmission.
