Dietitians' opinions regarding refeeding syndrome, clinical guidelines and extended scope of practice

Refeeding syndrome (RFS) prevalence rates vary across studies depending on the criteria used for assessment and identification. For registered dietitians, the assessment and management of RFS is highly reliant on daily serum electrolyte values; however, registered dietitians working within Australia do not currently possess laboratory test ordering privileges. We aimed to examine the opinions of registered dietitians regarding RFS identification, management and guidelines and the option of using extended scope of practice to order electrolyte monitoring autonomously.

A multi-method action research approach was used, incorporating two projects. The first was a survey examining Australian registered dietitians' (n = 187) opinions regarding RFS identification, management and guidelines, and autonomous electrolyte monitoring. To establish if results were similar internationally, an interview was conducted with 22 registered dietitians working within 10 different countries. Data were analysed using chi-square tests and thematic analysis.

Australian registered dietitians (75%) identify patients at risk of RFS at a high rate of more than once per fortnight, with 74% reporting that they have previously worked with a patient diagnosed with RFS. Results varied internationally, with respondents from eight countries reporting that RFS is a problem within acute care versus respondents from five countries having never treated a patient with RFS. The majority (≥89%) of registered dietitians desire new guidelines and the option to order patient electrolyte monitoring autonomously.

Our findings suggest that more stringent tools for the identification of RFS are necessary. There was limited uniformity across countries, and updated practice guidelines are needed.
