Extending the scope of dietetic practice in a regional setting: Dietitians credentialed to insert and manage nasogastric tubes.

BACKGROUND & AIMS

To describe the process of credentialing and implementing dietitian insertion of nasogastric tubes (NGTs) in a regional setting in Australia, and report on patient outcomes, timeliness and safety of insertion, and staff acceptance.

METHODS

An observational, mixed-methods study of service and patient outcomes was undertaken during the 2 years (2018-2020) following the implementation of dietitian credentialling for the insertion and management of NGTs. Data relating to the insertion of NGTs by credentialled dietitians were collected prospectively. A staff survey was circulated during and after the data collection period. Data has been reported descriptively.

RESULTS

The model of care was successfully implemented with two dietitians credentialed to insert NGTs. There were 38 unique occasions of NGT insertions for 31 individual patients. Eighty-seven percent (n = 33) of cases were inpatients. NGT insertion was successfully performed by the dietitian 82% of the time (n = 31). No medical complications relating to NGT insertion were reported following a dietitian inserted NGT, with the exception of one incidence of mild epistaxis. The average insertion time was 25.5 min (14.1), the average number of insertion attempts by a dietitian was 1.7 (1.27) and on one occasion more than one x-ray was required.

CONCLUSION

This study supports the recommendations of Dietitians Australia that this model of care is viable as an extended scope of practice model of care for dietetic departments across Australia. This evaluation adds to the evidence base for extended scope of practice and informs future directions for the service and training of dietitians.
