Outcomes
From a total cohort of 7212 hospitalizations with a primary diagnosis of ventricular and underwent catheter ablation, a total of 232 (3.2%) patients had in-hospital mortality; 113 patients had CKD and 119 did not have CKD. CKD was associated with increased odds of mortality. Adjusted OR was 2.24, 95% CI (1.29-3.88), p<0.01.
From 292 readmissions carried a primary diagnosis of ventricular tachycardia, 88 of which were patients with CKD on index admission. CKD on index admission was not associated with increased risk of 30-day readmission due to ventricular tachycardia. Adjusted OR was 1.35, 95% CI (0.78-2.31), P= 0.27.
In terms of acute kidney injury 1348 had acute kidney injury of whom 726 patients had baseline CKD. Presence of CKD was associated with increased risk of acute kidney injury in adjusted multivariate regression model. Adjusted OR was 3.69 95% CI (2.87-4.74), P<0.01.
Mean length of stay in our cohort was 6.40 days. Mean length of stay in patients without and with CKD was 5.69 and 8.73 days, respectively. After adjustment, patients with CKD had increased mean length of stay of 1.58 days and the difference was statistically significant, P<0.01. (Table 2)
Mean hospital charges in our cohort was 188014 USD. Mean hospital charges in patients without and with CKD was 176249 USD and 226796 USD, respectively. After adjustment, there was a mean difference of 27599 USD and the difference was statistically significant, P=0.012. (Table 2)
