Evaluation of the Effectiveness of Delirium Preventive Care Protocol

Study Overview
=================
Brief Summary
-----------------
The prospective, randomized controlled experimental trial investigates the effectiveness of delirium preventive care protocol for hip fracture patients.

Detailed Description
-----------------
The aim of this prospective, randomized controlled experimental trial is to evaluate the effectiveness of delirium preventive care protocol on pain, functional status, sleep quality and delirium prevention in patients with hip fracture. This research was conducted at a training and research hospital's orthopedics and traumatology department. The study sample was compromised of 80 patients with hip fracture. Intervention and control groups were applied after block randomization. Study data was collected by using Patient Information Form, Mini-Cog Test, Confusion Assessment Method, Visual Analogue Scale, Barthel Index, Mini Nutritional Assessment-Short Form and Richards Campbell Sleep Questionnaire. The patients in the intervention group were provided with nursing care in accordance with the delirium preventive care protocol developed with the support of literature. In the control group, routine nursing care was provided in line with the clinical procedure. The data was analyzed by using number, percentage, mean, standard deviation, median, Interquartile Range, Student's t test, Mann-Whitney U test, Pearson's chi square test, Fisher corrected chi-square test, ANOVA test, Paired Sample t test, Friedman test, Wilcoxon test and Cronbach α coefficient.

| --- | --- |
| Experimental: Intervention<br>Participants who met the criteria for inclusion in the study and volunteered to participate in the study were divided into experimental and control groups by block randomization method. After obtaining written informed consent, the Patient Information Form, Mini Nutritional Assessment- Short Form, Confusion Assessment Method, Barthel Index and Visual Analog Scale were applied to patients. Nursing care was applied to hip fracture patients in the experimental group in accordance with the care protocol developed to prevent delirium. Delirium preventive care protocol was consist of; psychosocial care, monitoring of oxygen saturation, prevention of dehydration, nutritional support, normal elimination, pain control, sleep regulation, avoidance of bladder catheterization and early mobilization. Confusion Assessment Method, Barthel Index and Richards-Campbell Sleep Questionnaire were repeated to patients on the first postoperative day and on the third day. | Procedure: Delirium Preventive Care Protocol<br>* Nursing care was applied to hip fracture patients in the experimental group in accordance with the care protocol developed to prevent delirium.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Richards-Campbell Sleep Questionnaire (RCSQ) | It was applied to patients at first admission to the clinic, on the first and third postoperative day. The scale developed by Richards in 1987; It consists of six items that assess the depth of night's sleep, the time to fall asleep, the frequency of waking up, the time to wake up, the quality of sleep and the noise level in the environment. Each item is evaluated on the chart from 0 to 100. A score of 0-25 indicates a very poor sleep and a score of '76 -100 indicates a very good sleep. The higher the scale score, the better the sleep quality of the patients. The total sleep score is calculated by taking the average of the depth of sleep, the time to fall asleep, the frequency of waking up, the time to stay awake and the quality of sleep. | 4 minutes. | 
| Barthel Index (BI) | Patients filled at frst admission to the clinic, on the first and third postoperative day was developed in 1965 by Mahoney and Barthel. It is used to determine the level of independence of individuals in their activities. The Barthel Index measures the social and physical function of daily life and consists of 10 items that assess the individual's ability to meet daily functions (nutrition, bathing, personal care, dressing, toileting, mobility on flat surfaces, transfer, climbing stairs, bowel and bladder function) without assistance. Each item is scored between 0-15 (varies according to the question). Barthel Index total scores vary between 0-100; 0-20 points completely addiction; 21-61 points severe addiction; Moderate dependence of 62-90 points; 91-99 points mild addiction; 100 points explain independence. In the studies using the Barthel Index, 60 points were taken as the limit and scores above 60 explain the ability to function independently. | 5 minutes. | 
| Visual Analog Scale (VAS) | It was applied to patients at first admission to the clinic, on the first and third postoperative day. It is used to measure the severity of pain. It is easy to use and the same in every language. At the two ends of a ten-centimeter line, two end definitions of the parameter to be evaluated are written and the patient is asked to indicate where his or her condition is appropriate by drawing a line or by pointing or pointing (0: I have no pain, 10: I have unbearable pain). The length of the distance from the absence of pain to the location of the patient indicates the pain of the patient. Less than three of this numerical expression indicates mild pain, three to seven indicates moderate pain, and more than seven indicates severe pain. | 1 minute. | 
| Mini Nutritional Assesment- Short Form (MNA-SF) | It was applied to patients at first admission to the clinic for evaluating of malnutrition. Its use in the elderly is recommended by the European Society for Clinical Nutrition and Metabolism (ESPEN). According to the screening score; 0-7 points indicate malnutrition, 8-11 points indicate malnutrition risk, 12-14 points indicate normal nutritional status. | 2 minutes. |
