It is unclear how extracorporeal membrane oxygenation use varies across paediatric cardiac surgical programmes and how it relates to post-operative mortality. We aimed to determine hospital-level variation in post-operative extracorporeal membrane oxygenation use and its association with case-mix adjusted mortality.

Retrospective analysis of 37 hospitals contributing to the Pediatric Cardiac Critical Care Consortium clinical registry from 1 August 2014 to 31 December 2019. Hospitalisations including cardiothoracic surgery and post-operative admission to paediatric cardiac ICUs were included. Two-level multivariable logistic regression with hospital random effect was used to determine case-mix adjusted post-operative extracorporeal membrane oxygenation use rates and in-hospital mortality. Hospitals were grouped into extracorporeal membrane oxygenation use tertiles, and mortality was compared across tertiles.

There were 43,640 eligible surgical hospitalisations; 1397 (3.2%) included at least one post-operative extracorporeal membrane oxygenation run. Case-mix adjusted extracorporeal membrane oxygenation rates varied more than sevenfold (0.9–6.9%) across hospitals, and adjusted mortality varied 10-fold (0–5.5%). Extracorporeal membrane oxygenation rates were 2.0%, 3.5%, and 5.2%, respectively, for low, middle, and high extracorporeal membrane oxygenation use tertiles (P < 0.0001), and mortality rates were 1.9%, 3.0%, and 3.1% (p < 0.0001), respectively. High extracorporeal membrane oxygenation use hospitals were more likely to initiate extracorporeal membrane oxygenation support intraoperatively (1.6% vs. 0.6% low and 1.1% middle, p < 0.0001). Extracorporeal membrane oxygenation indications were similar across hospital tertiles. When extracorporeal cardiopulmonary resuscitation was excluded, variation in extracorporeal membrane oxygenation use rates persisted (1.5%, 2.6%, 3.8%, p < 0.001).

There is hospital variation in adjusted post-operative extracorporeal membrane oxygenation use after paediatric cardiac surgery and a significant association with adjusted post-operative mortality. These findings suggest that post-operative extracorporeal membrane oxygenation use could be a complementary quality metric to mortality to assess performance of cardiac surgical programmes.

To characterise the current approach to sedation, analgesia, iatrogenic withdrawal syndrome and delirium in paediatric cardiac ICUs.

A convenience sample survey of practitioners at institutions participating in the Pediatric Cardiac Critical Care Consortium conducted from September to December 2020.

Paediatric cardiac ICUs.

Survey responses were received from 33 of 42 institutions contacted. Screening for pain and agitation occurs commonly and frequently. A minority of responding centres (39%) have a written analgesia management protocol/guideline. A minority (42%) of centres have a written protocol for sedation. Screening for withdrawal occurs commonly, although triggers for withdrawal screening vary. Only 42% of respondents have written protocols for withdrawal management. Screening for delirium occurs “always” in 46% of responding centres, “sometimes” in 36% of centres and “never” 18%. Nine participating centres (27%) have written protocols for delirium management.

Our survey identified that most responding paediatric cardiac ICUs lack a standardised approach to the management of analgesia, sedation, iatrogenic withdrawal, and delirium. Screening for pain and agitation occurs regularly, while screening for withdrawal occurs fairly frequently, and screening for delirium is notably less consistent. Only a minority of centres use written protocols or guidelines for the management of these problems. We believe that this represents an opportunity to significantly improve patient care within the paediatric cardiac ICU.

We aimed to assess the current nutritional practices in postoperative patients with Congenital Heart Disease.

Cross-sectional electronic survey was sent to members of The Pediatric Cardiac Intensive Care Society.

In Total, 52 members of the Pediatric Cardiac Intensive Care Society responded to the survey consisting of 14% paediatric intensivist, 53% paediatric cardiac intensivist, and 33% nurse/nurse practitioner with a median of 10 years of experience. There was an even distribution between intensivist (55%) and dietitian or nutritionist (45%) in nutrition management. Ninety-eight percent of respondents report that they would feed patients on inotropic or vasoactive support. Only 27% of respondents reported using indirect calorimetry in calculating resting energy expenditure which is the current gold standard. Academic hospitals compared to non-academic hospital were most likely to report feeding patients within 24 hours postoperative (p = 0.014). Having a feeding protocol was associated with feeding within 24 hours postoperative (p = 0.014) and associated with >50% goal intake by 48 hours postoperative (p = 0.025).

Substantial variation in feeding practice still exists despite the American Society for Parenteral and Enteral Nutrition guidelines from 2017. Report of institutional established feeding protocol was associated with increased early feeding and reaching goal feeds by 48 hours postoperative. Very few centres reported use of indirect calorimetry in postoperative paediatric cardiac intensive care patients and many respondents lacked knowledge about applications in this population. Additional work to determine optimal feeding pathways and assessment of caloric needs in this population is needed.
