A Canadian survey of perceived barriers to initiation and continuation of enteral feeding in PICUs.

OBJECTIVE

Clinicians believe nutrition support is important; however, delivery of enteral nutrition may be delayed or interrupted due to a lack of guidelines or perceived contraindications to administration. The aim of this national survey was to examine the knowledge and perceived barriers among clinicians which prevent enteral nutrition administration to PICU patients.

DESIGN

The survey consisted of 23 questions (19 primary and four branching). The survey was validated using a semistructured pilot test by three pediatric critical care intensivists and two pediatric critical care registered dietitians external to the study team.

SETTING

The survey was electronically distributed to clinicians in all PICUs across Canada.

POPULATION

One hundred sixty-two PICU clinicians, including 96 staff intensivists, eight clinical assistants, 36 fellows, and 22 registered dietitians from PICUs across Canada.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

The survey was administered from January to March 2013. The response rate was 50% (55 staff intensivists, two clinical assistants, nine fellows, and 15 registered dietitians). There was high variability among clinicians regarding reasons to delay the onset of enteral nutrition or interrupt enteral nutrition administration. High variability (> 70% agreement and < 10% disagreement or vice versa) was found for some reasons to delay or interrupt enteral nutrition, including lactates (rising or > 2 or > 4 mmol/L), high gastric residual volumes, CT/MRI scans, and hypoplastic left heart syndrome. Sixty-eight percent of PICU clinicians reported no written feeding protocol to be in place.

CONCLUSIONS

Overall, there is high variability among clinicians regarding acceptable procedural and clinical barriers to enteral nutrition administration; this may be improved by a standardized feeding protocol. Therefore, further research must be conducted to provide clinicians with evidence to support their practices for enteral nutrition administration.
