Abstract
Background
Indirect calorimetry is recommended as the reference method for determining energy expenditure and guiding energy delivery in critical care nutrition practice guidelines. However, the availability and use of indirect calorimetry in Australian and New Zealand intensive care units (ICUs) is unknown.
Objectives
To report on the availability and use of indirect calorimetry in Australian and New Zealand ICUs.
Methods
A binational multicentre observational study of nutrition practices was conducted in adult ICUs over a 1-week period in February 2021. All adult ICUs were invited to participate via multiple forums. Participating sites completed a once-off form on hospital and nutrition services which included questions relating to the availability and frequency of use (daily, fortnightly, monthly, and do not use) of indirect calorimetry. Data were collected on the type of device used and barriers to use. Data are reported as n (%).
Results
Forty-four ICUs reported data on hospital and nutrition services. Indirect calorimetry was available in 13 of 44 sites (30%): 12 sites in Australia and one in New Zealand. The COSMED Quark RMR (6/13 [46%]) and Q-NRG+ (5/13 [38%]) devices were the most commonly available. Indirect calorimetry was most frequently used on a weekly (4/13 [31%]) or monthly basis (4/13 [31%]). One site (8%) reported using indirect calorimetry fortnightly, with the remaining sites (4/13 [31%]) reporting that they do not use indirect calorimetry due to a lack of training (1/4 [25%]), no funding for consumables and a lack of training (1/4 [25%]), and for reasons not further specified (2/4 [50%]).
Conclusions
In 2021, indirect calorimetry was available in 30% of ICUs across Australia and New Zealand. However, only one-third of sites used this technology weekly, with reasons limiting use including a lack of training and funding for consumables. Expanding dedicated training programs and improving funding models may help overcome these barriers.
