the effect of digital window on day and night perception status and sleep quality in intensive care patients

Conditions: Coronary Artery Diseases; Heart Valve Diseases

Summary: the research will be carried out in the cardio vascular surgery (cvs) intensive care unit (icu) of ankara training and research hospital (trh) . patients will be divided into two experimental (n=24) and control (n=24) groups. simple randomization method will be used in the study, provided that there are equal numbers of male and female patients in the experimental and control groups, regardless of the age of the patients. patients in the experimental group will use a digital window. the "patient information form","richard-campbell sleep questionnaire_rcsq " and " day and night perception form" will be used in the data collection phase. ethics committee approval was received from ankara yıldırım beyazıt university ethics committee in order to conduct the study.

this research will be carried out as a randomized controlled experimental study to investigate the effect of the digital window on day and night perception status and sleep quality in intensive care patients. the research population consists of patients who underwent cabg and heart valve surgery and were admitted to the cvc icu of ankara training and research hospital. sample size calculation in order to calculate the sample size, a pilot study was conducted with 6 patients, three in the experimental group and three in the control group, and these pilot study data were used. as a result of the power analysis made with the help of the g\*power 3.0.10 program, the power of the study was found to be 80% for 2 groups and 3 repetitive study designs with an f=0.20 effect size and 5% margin of error. as a result, at least 42 samples in total, 21 of which were in the experimental group and 21 in the control group, were found to be sufficient. considering that the sample size obtained is the lowest limit and the patients have the possibility of going into delirium under intensive care conditions or giving up on continuing to work afterward, considering that the losses may be high, 15% of the number determined according to the sampling calculation was calculated and 48 patients who met the criteria for inclusion in the study were sampled. in experimental studies, it is recommended that the sample loss should not be more than 10-15%. randomization a simple randomization method will be used in the study, provided that there are equal numbers of male and female patients in the experimental and control groups, regardless of the age of the patients. whether the first female and first male patients who will come at the beginning of the study will be in the experimental group or the control group will be determined by drawing lots. the following patients will be divided into two groups, according to the order of arrival, the same-sex patients in the experimental group and the control group. data collection tools: the data in the research; patient information form, richard-campbell sleep questionnaire_rcsq will be collected using the day and night perception form. research implementation whether the first female and first male patients to come to the cvs icu on the day of surgery will be the experimental group or the control group will be determined by drawing lots. the following patients will be divided into two groups, according to the order of arrival, same-sex patients in the experimental group and the control group. in this way, it is planned to establish a balance between the groups according to gender. the patients who will be assigned to the experimental group will sleep on the 1st, 2nd, and 3rd beds, and the patients who will be assigned to the control group will sleep in the 4th, 5th, and 6th beds. data collection will be completed by the researcher by completing the day and night perception form and the richards campbell sleep scale (post-test) on the 1st, 2nd and 3rd days of post-op for the patients in the experimental group who are in the field of view of the digital window and the patients in the control group who are not in the field of view of the digital window. night and day perception form will be administered twice a day, once in the morning and in the evening, and richards campbell sleep scale will be administered once in the morning to each patient at the same time interval.

Eligibility criteria:
