Exploring the current usage of and attitudes towards transanastomotic tube (TAT) feeding in infants born with duodenal atresia: a survey of practice in the UK.

BACKGROUND

Despite evidence demonstrating clinical and cost benefits of transanastomotic tubes (TATs), following repair of congenital duodenal obstruction they are used in a minority of infants in the UK. Most infants are fed using parenteral nutrition (PN) (sometimes in combination with a TAT). This variation is unexplained by clinical or demographic factors. We aimed to understand why this is and the barriers to practice change.

METHODS

UK-based clinicians (surgeons, neonatologists, dietitians and specialist nurses) completed an online mixed methods survey. Open-ended replies were summarised thematically. Data were analysed using descriptive and inferential statistics.

RESULTS

109 clinicians (24 neonatologists, 7 nurses, 3 dietitians, 75 surgeons) from all 25 UK neonatal surgical units completed the survey. 88% (n=96/109) stated TAT use was decided solely by surgeons, driven primarily by considerations of providing appropriate nutrition and risks; 36% of surgeons felt TATs should always be used where possible. Decisions about central venous catheters (CVCs) were made by neonatologists (28%, n=31/109), surgeons (17%, n=18/109), jointly (48%, n=52/109) or 'other' (7%, n=8/109). Neonatologists and surgeons prioritised providing appropriate nutrition and risks when deciding whether to use CVCs/PN; surgeons rated a lack of supporting research and TATs' risks as key barriers to TAT usage. Costs and parents' preferences had limited influence on TAT and PN usage.

CONCLUSIONS

Increased TAT usage requires surgeons to be persuaded of TATs' efficacy and safety, and neonatologist recognition that exclusive TAT feeding (ie, without CVCs/PN) can provide adequate nutrition. Further work is required to appreciate how best to achieve this.
