Abstract

fetched live from OpenAlex

BackgroundIndex hospital costs for transcatheter aortic valve replacement (TAVR) remain high. Next-day discharge (NDD) is a safe and feasible strategy in select patients. We sought to explore cost savings associated with NDD TAVR.MethodsWe conducted a retrospective observation cohort study of all fee-for-service Medicare beneficiaries who underwent elective, uncomplicated, transfemoral TAVR in 2016. We employed a cross-sectional regression analysis to estimate risk-adjusted hospital costs savings of NDD relative to longer length of stay (LOS), and logistic regression to determine differences in direct home discharge and readmission.ResultsAmong 14,765 patients (59.2% of all TAVR), 2,169 (14.7%) were identified as NDD. They were younger (81.3 vs. 82.2, p < 0.01), more likely to be male (63% vs. 52%, p < 0.01), and had lower Charlson Comorbidity Index scores (2.73 vs. 2.98, p < 0.01). The adjusted cost for NDD was $7,499 lower compared to non-NDD (p < 0.001), and $5,188 when controlling for hospital fixed effects (p < 0.001); estimated total cost savings ranged from $6,522,183 to $16,265,331. NDD was associated with higher rates of discharged home (83% vs. 59%, p < 0.0001) without home health (16% vs. 28%, p < 0.0001), and lower incidence of readmission at 30 days [OR 0.72 (0.61–0.86), p = 0.0003], 60 days [0.71 (0.61–0.82), p < 0.0001] and 90 days [0.74 (0.65–0.85), p < 0.0001] than non-NDD.ConclusionsThere is significant heterogeneity in LOS after TAVR. Cost savings could be achieved with the implementation of clinical pathways and other strategies. Future research is needed to fully capture the multiple effects associated with LOS.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
