Development of a Mobile Application and Determination of Its Effects

Developing and Determining the Effect of Mobile Application for Patients Who Will Have Cardiac Surgery and Cardiovascular Surgery Intensive Care Unit Nurses

It has been determined that patients who have undergone heart surgery have a lack of knowledge about preoperative preparation and postoperative intensive care unit. In order to eliminate the lack of knowledge, patient education has gained importance in the preoperative period. At the same time, it is stated that nurses working in cardiovascular surgery intensive care units need continuous education to cope with the difficulties related to the increasing complexity of patient conditions and technology. With the advancement of technology, mobile applications have become an integral part of the continuous education of patients and nurses. This project was planned to evaluate the effect of the mobile application to be developed for patients who will undergo heart surgery on patient outcomes and the effect of the mobile application to be developed for nurses who provide patient care in intensive care units on the self-efficacy of nurses. In the first step of the project, the content of the mobile application will be developed, expert opinions will be obtained and the comprehensibility of patients and nurses will be tested. The software of the mobile application will be completed by shooting the necessary videos for the final content. In the second step of the project, the effect of the developed mobile application on anxiety, comfort and intensive care unit experiences in patients who meet the inclusion criteria will be examined. A randomized controlled experimental design will be used in this stage. State-Trait Anxiety Inventory, Early Postoperative Comfort Scale (EPQI), Intensive Care Experiences Scale will be used to collect data. Self-Efficacy Scale will be applied to nurses without randomization before and after using the mobile application. Data obtained in the study will be evaluated in a computer environment using SPSS data package program. In statistical decisions, p<0.05 level will be accepted as a significant difference indicator.

Study Overview

• Status: Active, not recruiting
• Conditions: Patient Education; Mobile Application; Cardiovascular Surgery
• Intervention / Treatment: Other: mobile application training

Detailed Description

Population and sample of the project:

The population will consist of all patients undergoing surgery in the Department of Cardiovascular Surgery at Lokman Hekim University Akay Hospital and treated in the ICU. Power analysis was performed to determine the number of people to be included in the study. The power of the test was calculated with the G*Power 3.1 programme. As a similar study in the relevant literature, Pehlivan (2021) calculated the effect size for the state anxiety difference as 0.646. In order to exceed the 90% value in determining the power of the study; 84 people, including 42 people in groups with a significance level of 5% and an effect size of 0.646, should be reached (df=82; t=1.664). Considering the high power of the test and the losses in the study, it was aimed to reach a total of 100 people, including 50 people in the groups.

All nurses working in the ICU of the Cardiovascular Surgery Department of Lokman Hekim University Akay Hospital will constitute the population of the study (N:10) and the nurses who volunteered to participate in the study will constitute the sample. Without randomisation for nurses, all nurses will be ensured to use the mobile application, pre-test and post-test will be performed.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Patients' anxiety	The State and Trait Anxiety scale can be scored between a minimum of 20 and a maximum of 80. As the score increases, the level of anxiety increases.	As soon as you are admitted to the clinic and on the first day after the surgery
blood pressure	Blood pressure will be measured manually	Immediately after admission to the clinic, after waking up in the intensive care unit and on the first day after surgery

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
comfort of patients	Early Postoperative Comfort Scale; The highest total score is 144 and the lowest total score is 24. A low score indicates poor comfort and a high score indicates good comfort.	1st day after surgery

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
satisfaction with mobile application	no scale will be used. Participants will be asked to evaluate the mobile application.	after using the app (1st day after surgery)
