Effectiveness of Nursing Orientation for the Reduction of Anxiety and Stress

Study Overview
=================
Brief Summary
-----------------
This study´s objective was to identify the effectiveness of nursing orientation for the reduction of anxiety and stress of patients that was waiting cardiac catheterization. Method. This is a randomized clinical trial. The sample consisted of patients that was waiting cardiac catheterization who were divided into two groups: intervention group (patients who received nursing orientation with a validated guidance manual about this procedure) and control group (patients who received the routine nursing orientation). The primary end points were the anxiety and stress, which was evaluated in two moments (before and after the nursing orientation). The State Anxiety Inventory (STAI-state) was used to assess anxiety and the Perceived Stress Scale (PSS-10) was used to assess stress. Prior to the collection, the research project was submitted to the Research Ethics Committee and the data was collected after its approval.

Detailed Description
-----------------
This study´s objective was to identify the effectiveness of nursing orientation for the reduction of anxiety and stress of patients that was waiting cardiac catheterization. Method. This is a randomized clinical trial. The sample consisted of patients that was waiting cardiac catheterization who were divided into two groups: intervention group (patients who received nursing orientation with a validated guidance manual about this procedure) and control group (patients who received the routine nursing orientation). The subjects were consulted about the desire to participate, and those who agreed, signed the consent form. The patients were randomized to one of two groups (control or intervention), according to the sequence determined by the Random System. Randomization was carried out by a teacher who did not participate of any phase of this study. After randomization, the patients were instructed how to fill out the instruments. The primary end points were the anxiety and stress, which was evaluated in two moments (before and after the nursing orientation). The State Anxiety Inventory (STAI-state) was used to assess anxiety and the Perceived Stress Scale (PSS-10) was used to assess stress. Subsequent to this first evaluation, the patients, both in the control group and in the intervention group, received the intervention by another profissional. After the patients were evaluated about anxiety and stress. Prior to the collection, the research project was submitted to the Research Ethics Committee and the data was collected after its approval.

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change from score of anxiety and stress | The anxiety and stress were evaluated using the State Anxiety Inventory (STAI-state) and the Perceived Stress Scale (PSS-10), immediately before and after interventions. The STAI -state consists of 20 items, with Likert responses ranging from 1 (Absolutely not) to 4 (Very High), obtaining values from 20 to 80 points, that the higher the score, the greater the patient's anxiety. Anxiety was categorized as follows: low anxiety (20-34 points), moderate anxiety (35-49 points), high anxiety (50-64 points) and very high anxiety (65-80 points). The PSS-10 has 10 items, whose score varies from 0 to 40 points, and the higher the scores, the greater the perceived stress of the patient. | The patients were followed for one day |
