title: Factors influencing selected lengths of ICU stay for coronary artery bypass patients.
abstract: This study examines factors influencing the length of intensive care unit stay for patients after coronary artery bypass surgery. Profiles of patients with selected lengths of ICU stay were identified for Group 1 (< or =1 day) and Group 2 (> or =2 days). Medical records of 175 patients who had undergone this procedure at an urban teaching hospital were reviewed. Patients who had a 1-day ICU length of stay were younger (mean=62.39, SD=10.88) and had comorbidities such as hypertension. Those patients with an ICU length of stay 2 days or longer were older (mean=68.18, SD=11.84) and had preoperative comorbidities such as congestive heart failure, chronic obstructive pulmonary disease, ejection fraction <50%, and need for an intra-aortic balloon pump. Atrial dysrhythmias, low cardiac output syndrome, renal insufficiency, and respiratory insufficiency were the postoperative complications associated with a prolonged ICU length of stay. Knowledge of the factors influencing selected lengths of ICU stay will enable nurses to choose patients for critical pathways and to anticipate postoperative problems in high-risk patients.
