ABSTRACT
Patients with hepatopulmonary syndrome (HPS) reportedly experience posttransplant morbidity and require more resources to care during perioperative period. The exact incremental increase of resources utilization compared with non-HPS population remains unknown. METHODS: In this single-center retrospective investigation, we compared the perioperative resources utilization of HPS patients undergoing orthotopic liver transplant (n = 28) to cohort without HPS (n = 739). Potential confounding variables were adjusted in the analysis and the multivariable log-linear regression were used. RESULTS: The overall hospital costs for HPS patients were about 27% higher compared with non-HPS patients (the ratio of geometric means, 1.27; 98.3% confidence interval, 1.09-1.47; P < 0). HPS diagnosis was independently associated with both longer intensive care unit stay (P < 0.001) and hospital stay (P < 0.001). The odds of being discharged to extended care facility were about 15 times higher for HPS patients comparing to non-HPS patients (odds ratio, 14.9; 97.5% confidence interval, 4.98-44.29; P < 0.001). There were no differences observed in odds of being readmitted to the hospital within 6 mo after the transplant (P = 0.75). CONCLUSIONS: HPS diagnosis was associated with longer intensive care unit stay, hospital stay, and increased hospital cost, together with higher odds of being discharged to extended care facility compared with non-HPS patients.
ABSTRACT
BACKGROUND: Care pathways are increasingly important as the shift toward value-based care continues; however, there is an inconsistent literature regarding their efficacy. The authors hypothesized that a total knee arthroplasty (TKA) care pathway, at a multihospital health system, would decrease cost, length of stay (LOS), discharges to inpatient facilities, postoperative complications at 90 days, and improve patient experience. METHODS: A historical control study with multivariable regression was used to determine the association of an evidence-based care pathway with episode of care cost, LOS, discharge disposition, 90-day postoperative complications, and Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores. RESULTS: In total, 6760 primary TKA surgeries were analyzed. Multivariable regression demonstrated that the full protocol period was associated with a decrease in episode of care costs (-8.501%, 95% confidence interval [CI] -9.639 to -7.350), a decrease in LOS (-26.966%, 95% CI -28.516 to -25.382), and an increase in discharges to home (odds ratio [OR] 3.838, 95% CI 3.318-4.446). The full protocol was not associated with a change in 90-day complications (OR 1.067, 95% CI 0.905-1.258) or patient willingness to recommend (OR 1.06, 95% CI 0.72-1.55). Adjusted episode of care cost savings, normalized to average national Medicare reimbursement, were $2360 per patient. CONCLUSION: TKA care pathways are an effective tool for standardizing care and reducing costs across a large health system. Further investigations are needed to develop interventions to consistently reduce complications. National scale implementation of care pathways in TKA could lead to estimated cost reductions of approximately $1.6 billion annually.
