As the authors did not assess inter-rater variability in their study, we performed an ad hoc experiment in our ICU. Ten nurses consecutively estimated and measured measuring tape the height of the same colleague while supine in bed. Height measured in an upright position early in the morning served as the accepted standard. The nurses were asked to perform as usual and without communicating results to the others. One of the main drawbacks of the article by Bojmehrani et al is that the measurement methods used were not sufficiently well described and, by consequence, were probably inconsistently used: the more exact each technique gets, the less margin of interpretation is left to the individual measurer.
In this sense, are you surprised that our nurses used three different techniques to measure height, namely, along the ventral part, along the dorsal part, or on the sides of the probationer, respectively? These results, together with the design of the paper by Bojmehrani et al, suggest that the variation in height measurements was due to the sum of two effects: the diverse techniques used by different examiners and the personal or intra-rater inaccuracy.
A more detailed description of the tape measurement method would probably have given more accurate results, maybe still with a bias but with a reduced variability. Thus, let's try to answer the third question. The study by Bojmehrani et al, as well as our experiment, highlights the point that improperly defined or inaccurately executed measurement techniques should be abandoned in favor of simpler and somehow self-explaining methods.
In this sense, the Chumlea method, which allows height estimation using knee-heel length, might be a valuable alternative. Accurate measurement is really a difficult task, and the list of possible problems could be easily extended. As a matter of fact, the height of our colleague in an upright position the accepted standard was remeasured 12 h later. At the end of his work day, he was 2 cm shorter.
