Association between care fragmentation and total spending after durable left ventricular device implant: a mediation analysis of health care-associated infections within a national Medicare-Society of Thoracic Surgeons INTERMACS linked dataset.
The purpose of this study was to examine the relationship between care fragmentation and total spending for durable left ventricular assisted device (LVAD) implant, and whether this relationship is mediated by infections. The researchers developed a measure of care fragmentation based on the number of shared medical professionals providing care to 4,987 Medicare beneficiaries undergoing LVAD implantation. The study found that the indirect effect of care fragmentation, through infections, was positive and statistically significant. The researchers concluded that higher care fragmentation associated with durable LVAD implantation is related with a greater incidence of infections and higher Medicare beneficiary payments.

Improving care pathways for acute coronary syndrome: patients undergoing percutaneous coronary intervention.
This study examined ways to improve care pathways for acute coronary syndrome (ACS) patients who are low-risk with no complications. They looked at 434,172 low-risk uncomplicated ACS patients eligible for early discharge from the Premier database and identified ACS care pathways. They compared percutaneous coronary intervention (PCI) types (trans-radial intervention [TRI] vs. transfemoral intervention (TFI) and by length of stay (LOS). Associations with costs and outcomes were tested using hierarchical, mixed-effects regression and projections of cost savings were obtained using modeling. More cost-savings were associated with TRI versus TFI. There was not an increased risk of adverse outcomes with a shorter LOS.
