The Effect of the Mobile Application-based Support Program on the Outcomes of Breast Cancer Patients in the Pandemic

Type of Research:

This research is planned to be carried out as randomized controlled analytical in order to determine the effect of the interactive nurse support program developed with the mobile application in breast cancer patients receiving chemotherapy during the Coronavirus pandemic process.

Hypotheses of the Research:

H0-1: The interactive nurse support program developed with a mobile application in breast cancer patients receiving chemotherapy during the coronavirus pandemic is not effective on patients' perception of social support.

H0-2: The interactive nurse support program developed with a mobile application in breast cancer patients receiving chemotherapy during the coronavirus pandemic. process is not effective on symptom management (symptom frequency, severity, level of distress).

H0-3: The interactive nurse support program developed with a mobile application in breast cancer patients receiving chemotherapy during the coronavirus pandemic. is not effective on the quality of life of the patients.

H0-4: The interactive nurse support program developed with a mobile application in breast cancer patients receiving chemotherapy during the coronavirus pandemic is not effective on patients' anxiety levels.

Population and Sample of the Research:

The population of the study consists of all breast cancer patients who applied to Ankara City Hospital Medical Oncology Department Outpatient Clinic to receive chemotherapy treatment.

In order to determine the sample size, a similar study (Zhu et al. 2018) was examined, and since the measurement tools were different, this study could not be used in calculating the sample number. However, when similar studies using mobile applications were examined in terms of sample size, it was seen that the number of patients in the intervention and control groups was 50 or less. For this reason, first of all, after the twelve-week follow-up of 50 patients in the control group is completed, the mobile application will be applied to 10 patients from the intervention group. When the twelve-week follow-up of 10 patients from the intervention group is completed, a power analysis will be made with the G. Power program using the data of 10 patients in each group, and the minimum number of people to be sampled will be calculated. The number of patients in the control group and intervention group will be increased according to the minimum number of people calculated. In order to prevent possible interaction between the patients, data will be collected from the intervention group patients after the follow-up of the control group patients is completed

Randomization Method:

During the preliminary implementation of the study, it was learned that based on the new working procedure of the Outpatient Chemotherapy Unit, all breast cancer patients who received anthracycline-based chemotherapy were given a treatment appointment at the same time in the afternoon. It was also found that the patients received chemotherapy in the same time interval in side-by-side seats and that the risk of mutual interaction was quite high. Contamination because of interaction between the intervention and control groups causes potential bias in the evaluation of the effect of the intervention in randomized controlled experimental studies. For this reason, patients who met the inclusion criteria were assigned to the intervention and control groups in a way that they would not come into contact with each other. To this end, the Simple Randomization Technique was used to determine which group the data would be collected from first (Random.org, 2021). Since the first group was determined as the control group in the randomization, the data were collected from this group first and then from the intervention group.

Data Collection Tools:

• Demographic and Clinical Information Form
• ECOG (Eastern Cooperative Oncology Group) Performance Scale
• Multidimensional Scale of Perceived Social Support (MSPSS)
• Memorial Symptom Rating Scale (MSDS)
• European Organization for Research and Treatment of Cancer- Quality of Life (EORTC-QLQ) C30 Scale
• QLQ-BR23 Module
• Beck Anxiety Scale
• Mobile Application Effectiveness Evaluation Form Pre-application In order to evaluate the comprehensibility 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 the Ankara City Hospital Medical Oncology Department Outpatient Clinic with the diagnosis of Breast Cancer to receive chemotherapy treatment. will be done. After the preliminary application, necessary changes will be made in the mobile application and data collection forms. If changes are made in the mobile applications and forms in line with the pre-application, the patients included in the pre-application will not be included in the research sample

Application of the 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 Turkish Linguist, 1 psychiatrist, 1 psychologist and 2 oncology nurses. At the same time, the content of the mobile application will be examined by 3 breast cancer patients and its intelligibility 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 mobile application content will consist of 5 parts:

• Coronavirus Pandemic Information Module
• Learning Module
• Discussion Module
• Ask the Expert Module
• Lived Stories Module 1.2. Creating the Technical Infrastructure of the Mobile Application The technical infrastructure of the application will be developed by the web software engineer.

Part 2: Implementation of Mobile Application and Collection of Data

• Patients with breast cancer who apply to the Department of Medical Oncology will be identified.
• Patients with breast cancer who meet the inclusion criteria will be identified (ECOG Performance Scale will be applied at this stage )
• Oral and written information will be given to the patients who are planned to be included in the study at the beginning of the study, and Informed Voluntary Consent Forms will be filled and signed according to their acceptance status.
• The first day of chemotherapy for patients who meet the inclusion criteria and accept to participate in the study will be determined. An appointment will be made one day before the chemotherapy treatment and data collection forms will be applied (day 0).

Practices for Patients in the Intervention Group

• Interviewing the patients in the intervention group the day before chemotherapy starts (day 0); *Demographic and Clinical Information Form

• Multidimensional Scale of Perceived Social Support
• EORTC QLQ-C30 Quality of Life Scale and QLQ-BR23 Module
• Beck Anxiety Scale will be applied.
• 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 training on the use of the mobile application.
• The mobile application will be applied during 4 cycles of chemotherapy (1 cycle/3 weeks or 1 cycle/2 weeks) from the first day of chemotherapy treatment.

The patient will record the symptoms (symptom type and severity) on the mobile application since the first chemotherapy treatment, 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 breast cancer and coronavirus will also be accessible at all times. This section covers the "Learning Module" of the mobile application.

• In addition to the video recording, which includes the management initiatives for the symptom experienced by the patient, the patient will forward 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 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.
• A reminder message will be sent to the patients who do not register their symptoms and log in to the system during the day, as of 20:00.

Patients will be able to enter the Discussion Module according to their preferences and share their experiences and opinions with other patients in the research group who have had the same experiences. This section covers the "Discussion Module" of the mobile application.

• Patients will be able to watch video recordings containing interviews with patients who have had the same experience and have come to the end of their treatment, whenever they want and as many times as they want. This section covers the "Lived Stories Module" of the mobile application.
• Patients will use the mobile application for 8 weeks or 12 weeks after receiving the first course of chemotherapy. Data will be collected with Multidimensional Perceived Social Support Scale, Memorial Symptom Rating Scale, EORTC QLQ-C30 Quality of Life Scale, QLQ-BR23 Module, Beck Anxiety Scale before chemotherapy is started and after each chemotherapy course, 4 times in total. When the cures are completed, a Mobile Application Efficiency Evaluation Form will be added to the data collection forms.

Applications for the Patients in the Control Group:

• The mobile application will not be installed on the phones of the patients in the control group, and the patients will receive standard care.
• Standard care; It includes the patients receiving chemotherapy in the outpatient clinic during the cure times given to them and informing the chemotherapy nurse about the pre-chemotherapy process and possible symptoms.
• Control group patients will be followed for 8 weeks or 12 weeks (4 cycles). Data will be collected with Multidimensional Perceived Social Support Scale, Memorial Symptom Rating Scale, EORTC QLQ-C30 Quality of Life Scale, QLQ-BR23 Module, Beck Anxiety Scale, before chemotherapy starts and after each chemotherapy cycle, 4 times in total.

Dependent and Independent Variables of the Research; Dependent Variables of the Research; symptom management, quality of life, perception of social support, level of anxiety. The independent variables of the research; sociodemographic and clinical characteristics of the patient, interactive nurse support mobile application Evaluation of Data The data to be obtained from the research will be analyzed with the SPSS 22 Program. Descriptive statistics (number, percentage, mean) will be used in the evaluation of the data. The relationship between the measured variables will be evaluated with the t-test, Pearson Chi-square test and Fishher's exact test. In the analysis of multiple dependent variables, 2-way Analysis of Variance and Regression Analysis will be used. A value of p<0.05 will indicate that the difference is significant, and a value of p>0.05 will indicate that the difference is not significant.
