(HealthDay News) — Preventable hospital-acquired complications (HACs) are associated with increased risk of adverse outcomes, especially among patients with chronic kidney disease (CKD), according to a study published online in Clinical Journal of the American Society of Nephrology.

Babak Bohlouli, from the University of Alberta in Canada, and colleagues examined the correlation of preventable HACs with mortality, length of stay (LOS), and readmission among adults. Data were included for 536,549 hospitalizations, including 45,733 with CKD.

The researchers found that in patients with CKD and at least one preventable HAC, the adjusted odds ratios of mortality during index hospitalization and from hospital discharge to 90 days were 4.67 (95% confidence interval [CI], 4.17 to 5.22) and 1.08 (95% CI, 0.94 to 1.25), respectively. In patients with 1 or more preventable HAC, the median incremental LOS was 9.86 days. The odds ratio for readmission was 1.24 (95% CI, 1.15 to 1.34) with preventable HAC. Relative to patients without CKD or preventable HAC, the odds ratios for mortality during index hospitalization were 2.22 (95% CI, 1.69 to 2.94), 5.26 (95% CI, 4.98 to 5.55), and 9.56 (95% CI, 7.23 to 12.56), respectively, for patients with CKD with no HAC, without CKD with HACs, and with CKD and HACs.
