 The surveys were answered on paper and the data included in an SPSS database by one of the researchers. Single questions in the 24-FS-ICU survey were analyzed according to the authors suggestions with minor modifications. Scores from items 1-6 in the published survey were transformed to scores from 0 to 100. The Mann-Whitney U test was used to determine any score differences between pre- and post-interventions. Differences of P0.05 were considered statistically significant.
