Our data suggest that a) FENO may be a practical tool to evaluate asthma severity and asthma control over time and b) FENO may be used as a marker of compliance with steroids even when FEV1 has not decreased significantly.

Objectives: Describe pediatric palliative care consult in children with heart disease; retrospectively apply Center to Advance Palliative Care criteria for pediatric palliative care consults; determine the impact of pediatric palliative care on end of life. Design: A retrospective single-center study. Setting: A 16-bed cardiac ICU in a university-affiliated tertiary care children’s hospital. Patients: Children (0–21 yr old) with heart disease admitted to the cardiac ICU from January 2014 to June 2017. Measurements and Main Results: Over 1,000 patients (n = 1, 389) were admitted to the cardiac ICU with 112 (8%) receiving a pediatric palliative care consultation. Patients who received a consult were different from those who did not. Patients who received pediatric palliative care were younger at first hospital admission (median 63 vs 239 d; p = 0.003), had a higher median number of complex chronic conditions at the end of first hospitalization (3 vs 1; p < 0.001), longer cumulative length of stay in the cardiac ICU (11 vs 2 d; p < 0.001) and hospital (60 vs 7 d; p < 0.001), and higher mortality rates (38% vs 3%; p < 0.001). When comparing location and modes of death, patients who received pediatric palliative care were more likely to die at home (24% vs 2%; p = 0.02) and had more comfort care at the end of life (36% vs 2%; p = 0.002) compared to those who did not. The Center to Advance Palliative Care guidelines identified 158 patients who were eligible for pediatric palliative care consultation; however, only 30 patients (19%) in our sample received a consult. Conclusions: Pediatric palliative care consult rarely occurred in the cardiac ICU. Patients who received a consult were medically complex and experienced high mortality. Comfort care at the end of life and death at home was more common when pediatric palliative care was consulted. Missed referrals were apparent when Center to Advance Palliative Care criteria were retrospectively applied.

Adoption of a chylothorax management protocol is feasible, and in our small cohort of patients implementation led to a significant decrease in the duration of chest tube utilisation, while eliminating practice variability among providers.

Human rhinovirus (HRV), the most common cause of upper respiratory infection in children, can present as bronchiolitis, pneumonia, or asthma exacerbations. The impact of HRV in infants and toddlers with congenital heart disease is poorly defined. A case-control study was performed to compare the clinical course for 19 young children with respiratory symptoms who tested positive for rhinovirus after heart surgery with that of 56 matched control subjects. The control subjects were matched by surgical repair, age, weight, and time of the year. Patients with known HRVs before surgery and control subjects with respiratory symptoms or positive test results for viruses were excluded from the study. Human rhinovirus infection was associated with more than a tenfold increase in the odds of noninvasive ventilation after extubation (odds ratio [OR] 11.45; 95 % confidence interval [CI] 3.97-38.67), a 12-fold increase in the probability of extubation failure (OR 12.84; 95 % CI 2.93-56.29), and increased use of pulmonary medications including bronchodilator and nitric oxide (p < 0.001). As a result, the hospital length of stay (HLOS) was two times longer than for the control subjects (p < 0.001), and the cardiac intensive care unit (CICU) length of stay (CICU LOS) was three times longer (p < 0.0001). The intubation time was significantly longer (p < 0.001), and the CICU respiratory charges were significantly greater (p = 0.001) for the infected patients. Human rhinovirus increases resource use and prolongs postoperative recovery after pediatric heart surgery. Surgery timing should be delayed for patients with rhinovirus if possible.

Blood testing rates were safely decreased in postoperative pediatric cardiac patients by changing laboratory ordering practices. In addition, packed RBC transfusion was decreased among the most complex patients.

Objectives To evaluate whether a quality improvement intervention reduces sternal wound infection (SWI) rates in children after cardiac surgery. Design This is a pre- and post-intervention quality improvement study. Setting A 16-bed cardiac intensive care unit in a university-affiliated pediatric tertiary care children’s hospital. Patients All patients undergoing cardiac surgery via median sternotomy from January 2010 to December 2014 are included. The SWI rates for primary closure (PC) and delayed sternal closure (DSC) are reported per 100 sternotomies. The hospital acquired infection (HAI) records were used to identify pre- intervention cases, while post-intervention cases were collected prospectively. Intervention Implementation of a sternal wound prevention bundle (SWPB) during the preoperative, intraoperative and postoperative periods for cardiac surgical cases. Measurements and Main Results During the pre-intervention period, 32 (3.8%) patients developed SWI while only 19 (2.1%) developed SWI during the post-intervention period (p=0.04). The rates of SWI following PC were not significantly different pre- and post-intervention (2.4% vs. 1.6%; p=0.35). However, patients with DSC had significantly lower post-intervention infection rates (10.6% vs. 3.9%; p=0.02). Conclusions Implementation of a SWPB during the perioperative period was associated with lower SWI rates in surgeries with DSC.

Objective: Retrospectively apply criteria from Center to Advance Palliative Care to a cohort of children treated in a cardiac ICU and compare children who received a palliative care consultation to those who were eligible for but did not receive one. Methods: Medical records of children admitted to a cardiac ICU between January 2014 and June 2017 were reviewed. Selected criteria include cardiac ICU length of stay >14 days and/or ≥ 3 hospitalisations within a 6-month period. Measurements and Results: A consultation occurred in 17% (n = 48) of 288 eligible children. Children who received a consult had longer cardiac ICU (27 days versus 17 days; p < 0.001) and hospital (91 days versus 35 days; p < 0.001) lengths of stay, more complex chronic conditions at the end of first hospitalisation (3 versus1; p < 0.001) and the end of the study (4 vs.2; p < 0.001), and higher mortality (42% versus 7%; p < 0.001) when compared with the non-consulted group. Of the 142 pre-natally diagnosed children, only one received a pre-natal consult and 23 received it post-natally. Children who received a consultation (n = 48) were almost 2 months of age at the time of the consult. Conclusions: Less than a quarter of eligible children received a consultation. The consultation usually occurred in the context of medical complexity, high risk of mortality, and at an older age, suggesting potential opportunities for more and earlier paediatric palliative care involvement in the cardiac ICU. Screening criteria to identify patients for a consultation may increase the use of palliative care services in the cardiac ICU.
