Abstract 4704: Prolonged In-Hospital Wait Times Does Not Affect Outcomes for Urgent Coronary Artery Bypass Surgery
Background: Many patients need urgent (same admission) coronary artery bypass grafting (CABG) surgery. Despite meeting Canadian “urgent CABG surgery wait time” benchmarks, there are resource constraints, which are present in many institutions, that sometime results in urgent patients being postponed. It is commonly believed that prolonged waiting for urgent CABG is associated with worse outcomes. Prolonged waiting can thus cause patient and healthcare staff frustration and is a major concern for healthcare managers. This frustration may be unnecessary if outcomes are not worse.
Objective: To determine the patient characteristics and outcomes of patients that wait between 3–5 days vs. 6 –10 days for urgent isolated CABG.
Methods: A prospectively collected database of all consecutive patients having isolated CABG from 1995 to 2007 was analysed. We compared demographic and various outcome parameters in patients requiring urgent surgery whom either waited 3–5 days (a time point chosen to avoid possible miscoding of urgent patients who were actually emergent, requiring surgery within 24 hours) or 6 –10 days in hospital prior to CABG. Percentages correlate to the cohorts and not for the whole database.
Results: Of 4236 urgent CABG patients, there were 841 patients that waited 3–5 days (inclusive) and 1209 patients that waited 6 –10 days (inclusive) for surgery. No significant differences were demonstrated in peri-operative morbidity or mortality. *=statistically significant. Please see table⇓:
Conclusions: We could not show a deleterious effect on morbidity or mortality of waiting in-hospital for up to 10 days for urgent CABG surgery. This may be useful information for patients, families, healthcare providers and resource managers.
