Why the study?

What factors are associated with prolonged length of stay following cardiac surgery in adult patients?

Key Points

Identify clinical determinants of prolonged total and intensive care unit stay after cardiac surgery and construct a preoperative risk-prediction model.
Retrospective observational study evaluating all adult patients who underwent cardiac surgery at a tertiary referral hospital in Oman between 2009 and 2013.
Assessed preoperative and operative clinical variables against prolonged total postoperative stay (≥11 days) and prolonged cardiac intensive care unit stay (≥5 days).
Prolonged total postoperative stay occurred in 30.5% of patients, with postoperative complications identified as the primary determinant alongside body mass index, surgical type, cardiopulmonary bypass, and packed red blood cell transfusion.
Prolonged intensive care unit stay occurred in 17% of patients, predicted by non-elective surgery, active congestive heart failure, renal failure, and combined coronary and valve operations (model area under the curve = 0.75).
Risk-score stratification categorized patients into three groups with observed intensive care unit prolonged stay probabilities of 11% for group 1, 26% for group 2, and 28% for group 3.

Structured PICO

What factors are associated with prolonged length of stay following cardiac surgery in adult patients?

Population

Adult patients who underwent cardiac surgery at a major referral hospital in Oman between 2009 and 2013.

Intervention

Risk factors for prolonged length of stay (e.g., non-elective surgery, current congestive heart failure, renal failure, combined CABG and valve surgery)

Outcome

Prolonged postoperative length of stay (≥11 days) and prolonged ICU length of stay (≥5 days)

Preoperative factors such as non-elective surgery, congestive heart failure, and renal failure can predict prolonged ICU stay after cardiac surgery, allowing for better resource allocation.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

May aid preoperative CICU risk stratification; leaves open external validation against existing systems.
