850 Length of Hospital Stay and Discharge Disposition in Transcatheter Versus Surgical Aortic Valve Replacement

Transcatheter aortic valve implantation (TAVI) is an attractive alternative to surgical aortic valve replacement (SAVR). Increases in the number of patients having TAVI compared to SAVR will have significant implications on resource utilisation. Data regarding length of stay and discharge disposition were obtained for all patients undergoing aortic valve intervention in Christchurch 2018. SAVR patients were excluded if the indication was endocarditis, bicuspid aortic valve, aortic regurgitation or coronary disease; received mechanical valve or concomitant treatment for another valve. Results are summarised in the table below:Tabled 1SAVRTAVIP-valueNumber3650Age (mean (SD), years)71.4 (6.09)80.5 (5.95)<0.0001Urgent procedure16 (44%)23 (46%)1ICU stay (mean (SD), hours)52.1 (27.4)0 (0)<0.0001Length of hospital stay (mean (SD), days)12.9 (13.1)6.58 (6.83)0.0043Procedure to discharge (mean (SD), days)6.30 (3.94)1.84 (1.84)<0.0001Next day discharge0 (0%)31 (62%)<0.0001Mortality in Hospital2 (5.5%)0 (0%)0.17Discharge to another facility11 (30%)1 (2%)0.0002Discharge Home23 (63%)49 (98%)0.0001 Open table in a new tab Despite being older, TAVI patients did not require ICU, were discharged sooner and were more likely to be discharged home. The majority of TAVI patients were discharged on the first day following the procedure.
