RESUMEN
Congenital heart disease (CHD), the most common congenital malformation, often requires surgical correction. As surgical mortality rates are low, a common quality marker linked with surgical outcomes is hospital length of stay (LOS). Reduced LOS is associated with better long-term outcomes, reduced hospital-acquired complications, and improved patient-family satisfaction. This project aimed to reduce aggregate median postoperative LOS for four CHD lesions from a baseline of 6.2 days by 10%. METHODS: This single-center study utilized the Institute for Healthcare Improvement model to achieve the project aim. A diuretic wean protocol implemented in April 2018 entailed weaning to a homegoing diuretic regimen upon transfer from the cardiac intensive care unit to the inpatient step-down unit. A discharge milestone checklist implemented in September 2018 contained milestones necessary for discharge and an anticipated date of discharge. Outcome measures included aggregate median postoperative LOS and ∆LOS. Balancing measures included cardiac intensive care unit bounce back, pleural chest tube replacement, and readmission rates. RESULTS: Our baseline aggregate median postoperative LOS for the lesions studied was 6.2 days. Following diuretic protocol implementation, the aggregate median LOS decreased to 4.4 days. Baseline ∆LOS decreased from 5.5 to 0.42 days. Postoperative cost fell by an average of $11,874. Balancing measures demonstrated no unintended consequences. CONCLUSIONS: Implementation of a diuretic wean protocol led to sustained improvement in postoperative LOS, and ∆LOS in a subset of CHD patients with no unintended consequences supporting that standardization of postoperative care is effective for improvement efforts and can reduce overall practice variation.
RESUMEN
Viral bronchiolitis is a relative contraindication to elective pediatric cardiac surgery. Nasopharyngeal swab utilizing polymerase chain reaction (PCR) screening for viruses known to cause bronchiolitis are commonly available. The objective of this study was to evaluate clinical outcomes in patients with nasopharyngeal viral PCR positive findings at the time of cardiac surgery. Retrospective review from January 2013 to May 2019 for patients with virus detected by PCR on nasopharyngeal swabs at the time of cardiac surgery. Single ventricle and two ventricle patients were compared to control group of age and procedure matched patients viral negative at the time of surgery. Outcome measures included OR extubation, reintubation, hospital length of stay, and mortality. For two ventricle patients (n = 81; control group = 165), there was no statistical difference in any outcome variable (OR extubation 74% vs 72%; p = 0.9; reintubation 9% vs 11% vs; p = 0.7; hospital length of stay 5 days (1-46) vs 4 days (2-131); p = 0.4; mortality 2 vs 1; p = 0.3). For single ventricle patients, there was no statistical difference in any outcome variable (OR extubation 81% vs 76%; p = 0.6; reintubation 14% vs 21% vs; p = 0.5; hospital length of stay 9.5 days (3-116) vs 15 days (2-241); p = 0.1; mortality 0 vs 3; (p = 0.6)). PCR is a sensitive test that fails to predict which patients will proceed to have a clinically significant infection. Viral bronchiolitis remains a relative risk factor for cardiac surgery; presence of detectable virus via nasopharyngeal swab with limited clinical symptoms may not be a contraindication to cardiac surgery.
