The Effect of a Mobile Application on Patient Outcomes in Colorectal Cancer Patients

The aim of this study is to determine the effect of the interactive nurse support program developed as a mobile application on patient outcomes (symptom management, quality of life, perception of social support and anxiety) in colorectal cancer patients receiving chemotherapy during the COVID-19 process; It was planned in a randomized controlled, single-blind design. In the study, a mobile application will be designed for colorectal cancer patients with the content created in line with the literature. In the application, the "about COVID-19" module, which includes information for colorectal cancer patients during the COVID-19 process, the "learning module" in which the symptoms and suggestions for colorectal cancer patients receiving chemotherapy are included, the "discussion" module where patients can share their knowledge and experiences with each other, The "ask the expert" module, where nurses and physicians can ask questions, will be comprised of the "lived stories" module and the communication sections, which include interview videos made with individuals who are in remission only after completing the treatment related to the disease. A pretest consisting of Personal Information Form, Multidimensional Perceived Social Support Scale EORTC QLQ-C30 and CR29 Quality of Life Scale, ECOG Performance Scale and Beck Anxiety Scale will be administered to all patients included in the study. The mobile application will be installed on the phones of the patients in the experimental group and they will be used for 12 weeks. Patients in the control group will receive standard care during this process and no intervention will be made. In the sixth and twelve weeks, all participants will be given a posttest. The change in symptom management, quality of life, perceived social support and anxiety levels of the experimental group after mobile application use will be evaluated.

Type of Research:

The research was randomized controlled, analytically planned.

Research Hypotheses:

H0-1: The interactive nurse support program developed with the mobile application in colorectal cancer patients receiving chemotherapy during the COVID-19 process has no effect on the quality of life of the patients.

H0-2: The interactive nurse support program developed with the mobile application in colorectal cancer patients receiving chemotherapy during the COVID-19 process has no effect on the social support perceived by the patients.

H0-3: The interactive nurse support program developed with the mobile application in colorectal cancer patients receiving chemotherapy during the COVID-19 process has no effect on the anxiety levels of the patients.

H0-4: The interactive nurse support program developed with a mobile application has no effect on symptom management in colorectal cancer patients receiving chemotherapy during the COVID-19 process.

Population and Sample of the Research:

The population of the research will be the colorectal cancer patients followed in the Ankara City Hospital Medical Oncology Department Outpatient Clinics.

Calculating Sample Size When previous similar studies on sample size were examined, no similar research could be found in terms of sample characteristics and measurement tools. For this reason, after reaching 10 people in the intervention and control groups, the minimum number of people to be included in the sample will be calculated by performing a power analysis from the research results.

In order to determine the sample size, a similar study (Zhu et al. 2018) was examined, but it was seen that the measurement tools were different. For this reason, after reaching 10 people in the research and control group, power analysis will be made with the G. Power program and the minimum number of people to be sampled will be calculated. It is aimed to increase the number of samples in order to increase the power of the research by guaranteeing the minimum number of people that will constitute the sample size.

Randomization Method:

Among the patients who applied to Ankara City Hospital Medical Oncology Department Outpatient Clinics with the diagnosis of colorectal cancer to receive chemotherapy treatment, patients who meet the criteria for inclusion in the study will be determined. In order to prevent possible interaction between patients who meet the inclusion criteria of the study, data wiil be collected from the control group first, according to the order of admission to the hospital, and after the target number is reached, data will be collected from the patients in the intervention group.

Data Collection Forms

1. Personal Information Form
2. Memorial Symptom Assessment Scale (MSDS)
3. EORTC QLQ-C30 and CR29 Quality of Life Scale

Pre-Application:

In order to evaluate the intelligibility and usability of the mobile application and data collection forms created for the interactive nurse support program, a preliminary application was made with 5 patients who met the criteria for inclusion in the study among the patients who applied to Ankara City Hospital Medical Oncology Department Outpatient Clinics with the diagnosis of Colorectal Cancer for chemotherapy treatment. will be done. After the preliminary application, necessary changes will be made in the mobile application and data collection forms. Patients included in the pre-application scope will not be included in the study sample.

Application of Research:

Part 1: Development of Mobile Application 1.1.Developing the Content of the Mobile Application The content of the mobile application will be created by the researcher as a result of extensive literature research. The content created will be submitted to expert opinion, including 1 oncologist, 1 surgical oncology specialist, 4 nurse lecturers, 1 psychiatrist, 1 psychologist, 1 Turkish linguist and 2 oncology nurses. At the same time, the content of the mobile application will be examined by 3 colorectal cancer patients and its comprehensibility will be evaluated. As a result of expert opinions and patient evaluations, arrangements will be made in the content of the mobile application and the mobile application will be finalized.

The content of the mobile application will consist of 5 parts:

* COVID 19 Information Module
* Learning Module
* Discussion Module
* Ask the Expert Module
* Lived Stories Module

Part 2: Implementation of Mobile Application and Collection of Data

* Patients with colorectal cancer who apply to the Department of Medical Oncology will be identified.
* Patients with colorectal cancer who meet the inclusion criteria will be determined (ECOG Performance Scale will be applied at this stage).
* At the beginning of the study, patients who are planned to be included in the study will be informed verbally and in writing about the study and it will be ensured that Informed Consent Forms are filled and signed according to their acceptance status.
* The first day of chemotherapy will be determined for patients who meet the criteria for inclusion in the study and accept to participate in the study. An appointment will be made one day before the chemotherapy treatment and data collection forms will be applied (day 0).

Applications for the Patients in the Experimental Group:

* Interviewing the patients in the experimental group the day before the start of chemotherapy (day 0); Personal Information Form, Multidimensional Perceived Social Support Scale, Quality of Life Scale, Beck Anxiety Scale will be filled.
* The mobile application will be installed on the patient's phone by the researcher. The patient will be registered to the program by creating a changeable user name.
* The patient will be given 15-20 minutes of online training on the use of the mobile application.
* The mobile application will be applied for a total of 12 weeks during 4 cycles of chemotherapy (1 cycle/3 weeks) from the first day of chemotherapy treatment.
* The patient will record the symptoms appearing since the first chemotherapy treatment (symptom type, frequency and severity) in the mobile application, and watch the relevant video recording according to the symptom experienced from the symptom management videos. The patient will be informed that he can record more than one symptom and watch all the videos as many times as he wants. Information texts on patient colorectal cancer and coronavirus will also be accessible at any time. This section covers the "Learning Module" of the mobile application.
* In addition to the video recording, which includes the management initiatives related to the symptom experienced by the patient, the patient will convey his/her individual questions to the researcher by text message or phone call, according to his/her preference. According to the method of conveying the patient's question, the patient's question will be answered by the researcher with the same method. As soon as written messages are sent, they will appear on the researcher's phone screen and the patient will be answered within 1 hour at the latest. If necessary according to the content of the questions regarding the treatment, care or symptom management submitted by the patient, the questions will be directed by the researcher to the oncology physician, who is the other manager in the Ask the Specialist module. The response from the physician will be communicated to the patient. This section covers the "Ask an Expert Module" of the mobile application.
