Randomization in this research will be done by block randomization method with a volume of four. The sequence of random allocation and the list of blocks will be obtained by the statistical consultant and with the help of R software. In this method, blocks are formed based on the variables in question. Block randomization is performed by randomizing participants into blocks, so that equal numbers are assigned to each group (intervention and control). Equal numbers of participants enter the groups in consecutive but equal time intervals. After each patient and family enters the ward, according to the prepared block of four (15 blocks of four) based on the sample size, in the first stage, each patient will be randomly placed in the A test group or the B control group. For example, after randomly selecting a block such as the ABAB block, patients are randomly placed in the test, control, test and control groups. After generating the random sequence, sampling is done by hiding the generated sequence. So that before assigning the individual, the assigned group is not known for the samples. This is done by putting a random sequence inside the envelope and choosing a non-transparent envelope. First, a random sequence is created, then based on the size of the research sample, a number of envelopes are prepared and each of the created random sequences is recorded on a card, and the cards are placed in the envelopes in order. In order to maintain a random sequence, the outer surface of the envelopes is numbered in the same order. Finally, the lid of the envelopes is glued and placed in a box in order. At the time of starting the registration of the participants, based on the order of entry of the eligible participants into the study, one of the envelopes is opened in order and the assigned group of that company The doer is revealed. Each patient's code will be assigned to his family member. People are assigned to the desired group in the order of their entry into the study and randomly through randomized blocks.
