- The P value concerns the differences between pre-IMC and IMC periods. The P value interaction tests whether the differences of studied relevant factors change from the pre-IMC period to the IMC period. In both tests, 10log-transformed costs were analysed. ICU, intensive care unit; IMC, intermediate care unit; LOS, length of stay; SD, standard deviation; TISS, Therapeutic Intervention Scoring System.
