Changes in coding of pneumonia and impact on the hospital readmission reduction program.
Researchers evaluated whether changes in diagnosis assignment explain reductions in 30-day readmission for patients with pneumonia following the Hospital Readmission Reduction Program (HRRP). They conducted a retrospective cohort study of Medicare discharges in HRRP-eligible hospitals; outcomes were 30-day readmission rates for pneumonia under both "narrow" and "broad" definitions that included certain diagnoses of sepsis and aspiration pneumonia. They concluded that changes in the coding of inpatient pneumonia admissions do not explain readmission reduction following the HRRP.

Changes in use of postacute care associated with accountable care organizations in hip fracture, stroke, and pneumonia hospitalized cohorts.
In this study, researchers examined changes in more and less discretionary condition-specific postacute care use associated with Medicare accountable care organization (ACO) implementation. They found that ACOs decreased spending on postacute care by decreasing use of discretionary services. In addition, ACO implementation was associated with reduced length of stay in skilled nursing facilities, while hip fracture patients used institutional postacute settings at higher rates. The authors also observed decreases in spending, readmission days, and mortality among pneumonia patients.
