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.
To report on the availability and use of indirect calorimetry in Australian and New Zealand ICUs.
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 (%).
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%]).
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.

在重症监护营养实践指南中，间接测热法被推荐为确定能量消耗和指导能量供给的参考方法。然而，澳大利亚和新西兰重症监护病房（ICU）中间接测热法的可用性及使用情况尚不清楚。
报告澳大利亚和新西兰ICU中间接测热法的可用性及使用情况。
2021年2月，在成人ICU中进行了一项为期1周的两国多中心营养实践观察性研究。通过多个论坛邀请所有成人ICU参与。参与的机构填写了一份关于医院和营养服务的一次性表格，其中包括与间接测热法的可用性和使用频率（每日、每两周、每月以及不使用）相关的问题。收集了所使用设备的类型和使用障碍的数据。数据以n（%）形式报告。
44个ICU报告了关于医院和营养服务的数据。44个机构中有13个（30%）可使用间接测热法：澳大利亚12个，新西兰1个。最常配备的设备是COSMED Quark RMR（6/13 [46%]）和Q-NRG+（5/13 [38%]）。间接测热法最常每周（4/13 [31%]）或每月（4/13 [31%]）使用一次。有1个机构（8%）报告每两周使用一次间接测热法，其余机构（4/13 [31%]）报告由于缺乏培训（1/4 [25%]）、没有消耗品资金且缺乏培训（1/4 [25%]）以及未进一步说明的原因（2/4 [50%]）而不使用间接测热法。
2021年，澳大利亚和新西兰30%的ICU可使用间接测热法。然而，只有三分之一的机构每周使用该技术，使用受限的原因包括缺乏培训和消耗品资金。扩大专门培训项目和改进资金模式可能有助于克服这些障碍。
