Statistical methods / analysis
This is an exploratory practice audit and hence no power calculation was conducted. Cohort 1 includes 127 patients for which data was collected in a prospective manner as part of a clinical audit over an 18 month time-period from February 2005. Cohort 2 will include prospectively collected patient data from 2018 onwards to match cohort 1, hence including 127 patients.

Continuous variables will be summarised with mean and standard deviation, or median and interquartile range, as appropriate. Categorical variables will be presented as n (%). Patient demographics will be compared between cohorts using t-tests or Mann-Whitney tests for continuous variables, and chi-square or Fishers Exact Test for categorical variables. The primary outcome of mean total delivered calories (kcal/day) will be compared between the two cohorts using an independent samples t-test for an unadjusted analysis, and in a multiple linear regression including cohort and baseline characteristics (age, sex, APACHE-II score at ICU admission) to control for any differences in patient demographics over time. Secondary energy and protein outcomes will be analysed for differences between cohorts and patients with and without head injuries via a linear model with fixed effects for cohort and head injury (Y/N) and tested with planned contrasts. Statistical significance will be assessed at p < 0.05.

Summary
Brief summary
Enteral nutrition (EN), delivered via a tube into the stomach, provided to critically ill patients is largely inadequate, resulting in muscle wasting and reduced physical function in the long-term. Numerous factors are known to influence nutrition delivery in the intensive care unit (ICU) such as interruptions for procedures, delayed initiation of feeding regimes, under or over prescription, and feed intolerance due to delayed gastric emptying. Further, recent evidence raises doubt as to the benefit of early vs delayed initiation of enteral nutrition and the delivery of calories to full prescribed target early in critical illness. Therefore, an exploration of whether there has been a change in nutrition delivery over time to reflect recommendations, and whether potential barriers to nutrition adequacy are as prevalent now as in the past, is required.
