Crude and Adjusted Outcomes After SAVR Between Being Treated at a TAVR Center, Compared With a Non‐TAVR Center, on Discharge Disposition, 30‐Day Readmission, and LOS
| TAVR Center | Non‐TAVR Center | Crude | Adjusteda | |||
|---|---|---|---|---|---|---|
| n (%) | n (%) | OR (95% CI) | P Value | OR (95% CI) | P Value | |
| Discharge dispositionb | ||||||
| Routine | 17 619 (80) | 7838 (77) | Ref | ··· | Ref | ··· |
| Transfer, short term hospital | 157 (1) | 39 (<1) | 1.79 (1.26–2.55) | 0.001 | 2.09 (1.43–3.07) | 0.0002 |
| Transfer, skilled nursing facility | 3973 (18) | 3053 (20) | 0.87 (0.82–0.92) | <0.0001 | 0.92 (0.85–0.99) | 0.02 |

| Length of stay, d | 6 (5–8) | 6 (5–8) | 0.04 (−0.12 to 0.20) | 0.63 | −0.09 (−0.26 to 0.08) | 0.29 |
CIE indicates change in estimate; IQR, interquartile range; LOS, length of stay; OR, odds ratio; SAVR, surgical aortic valve replacement; TAVR, transcatheter aortic valve replacement.
a
Adjusted for year of surgery, age, sex, primary insurance, median household income in the patient's zip code, Charlson comorbidity index, hospital teaching status, and hospital size; age, and Charlson comorbidity index were modeled as a restricted quadratic splines.
b
Compared with routine discharge.
c
Only assessed among patients discharged alive after SAVR.
