Redesigning inpatient care: Testing the effectiveness of an accountable care team model.

BACKGROUND: US healthcare underperforms on quality and safety metrics. Inpatient care constitutes an immense opportunity to intervene to improve care. OBJECTIVE: Describe a model of inpatient care and measure its impact. DESIGN: A quantitative assessment of the implementation of a new model of care. The graded implementation of the model allowed us to follow outcomes and measure their association with the dose of the implementation. SETTING AND PATIENTS: Inpatient medical and surgical units in a large academic health center. INTERVENTION: Eight interventions rooted in improving interprofessional collaboration (IPC), enabling data-driven decisions, and providing leadership were implemented. MEASUREMENTS: Outcome data from August 2012 to December 2013 were analyzed using generalized linear mixed models for associations with the implementation of the model. Length of stay (LOS) index, case-mix index-adjusted variable direct costs (CMI-adjusted VDC), 30-day readmission rates, overall patient satisfaction scores, and provider satisfaction with the model were measured. RESULTS: The implementation of the model was associated with decreases in LOS index (P < 0.0001) and CMI-adjusted VDC (P = 0.0006). We did not detect improvements in readmission rates or patient satisfaction scores. Most providers (95.8%, n = 92) agreed that the model had improved the quality and safety of the care delivered. CONCLUSIONS: Creating an environment and framework in which IPC is fostered, performance data are transparently available, and leadership is provided may improve value on both medical and surgical units. These interventions appear to be well accepted by front-line staff. Readmission rates and patient satisfaction remain challenging.

Lung preservation: pulmonary flush route affects bronchial mucosal temperature and expression of IFN-gamma and Gro in regional lymph nodes.

Optimal lung preservation via flush of the pulmonary vasculature minimizes early graft failure post-lung transplantation. We hypothesized that the route of pulmonary flush has differential effects on thermal gradients in the lung and expression of inflammatory mediators. Swine underwent antegrade flush (AG) via pulmonary artery; AG/RG: antegrade + retrograde flush via pulmonary veins or AG/BA: antegrade + bronchial artery flush via bronchial artery. Temperatures were recorded in bronchial mucosa and peribronchial lymph nodes. RT-PCR was utilized to detect cytokine gene expression in the nodes. AG/BA flush resulted in greatest cooling of bronchial mucosa and lymph nodes (p < 0.001). The route of flush did not affect expression of RANTES, MCP-1, IL-8, IL-1beta, TNF-alpha or IL-6. However, expression of Gro was reduced 4-h post-preservation in all groups. Only AG/BA resulted in decreased IFN-gamma transcripts. These data show that, compared to AG or AG/RG, AG/BA flush results in the greatest cooling of lung compartments and down regulates lymph node expression of a cytokine and chemokine that have key roles in inflammation and immunity. These data suggest that pulmonary flush via AG/BA during donor harvest may be optimal to decrease the risk of early graft failure.
