The process of allocation was preceded by an initial examination of the injured by a triage nurse. This was followed by the assessment of the patients by one of the researcher to verify suitability for the trial. When the patients were found suitable for entering the trial and signed a written consent they were randomized to one of the groups. The study describes the method of allocation (sealed, numbered envelopes that contained randomized allocations) however does not mention any method that would be used to balance the randomisation. Demographic information was acquired at the beginning of the study (during the admission of the patient) and it was used to identify whether any differences between the studied groups existed.The study was not a blind trial, but a so called open trial. In this case the injured patients as well as the emergency nurse practitioner or senior house officers treating them were aware of the nature of the study. In this particular case it was impossible to carry out a single blind or a double blind trial (LoBiondo-Wood, 2002). The level of patient satisfaction was measured using a questionnaire and the patients were asked to complete it immediately following the treatment. While this questionnaire reduces observes bias the case of the assessment of the quality of clinical notes can hardly be considered unbiased despite the use of an established audit tool.
