Why the study?

Does heart rate variability measured on postoperative day 1 predict length of stay in patients undergoing abdominal aortic surgery?

Population

Implication

May support POD1 HRV for LOS risk stratification after aortic surgery; hypothesis-generating and needs prospective validation.

Structured PICO

Does heart rate variability measured on postoperative day 1 predict length of stay in patients undergoing abdominal aortic surgery?

P
Population
106 patients admitted to the surgical intensive care unit (ICU) after abdominal aortic surgery
I
Intervention
Heart rate variability (HRV) measurement via 24-hour Holter recording on postoperative day 1
O
Outcome
Length of stay (LOS) dichotomized into short (<= 7 days) and long (> 7 days)

Decreased intermediate-term heart rate variability on postoperative day 1 independently predicts longer length of stay in patients undergoing abdominal aortic surgery.
