Effect of Education in Rheumatoid Arthritis

Study design and participants This pretest and posttest prospective study was conducted as randomized controlled between February 2019 and October 2019 in the outpatient and inpatient clinics of the Department of Rheumatology of a university hospital in Edirne, Turkey.

Two study groups, control (n = 40) and intervention (n = 40) were randomized controlled groups with 80% power analysis and 95% confidence interval. A single-blind technique was used to eliminate any bias. The patients were not informed of the group to which they belonged. The patients were selected using a simple random sampling method and divided into intervention and control groups using the Research Randomizer program. In the intervention group, 40 women with RA were interviewed at baseline (first interview). In the 3rd month (last interview), eight patients were excluded for the following reasons: four did not wish to continue the study, three could not be reached, and one patient did not complete the forms. Therefore, 32 women with RA were finally included in the intervention group. In the control group, 40 patients were interviewed at baseline. In the 3rd month (last interview), seven patients were excluded for the following reasons: four patients did not wish to continue the study and three patients could not be reached. Therefore, 34 women with RA were finally included in the control group. The study included a total of 66 women with RA, including intervention (n= 32) and control (n= 34) groups. Flow chart of data collection for women with RA is presented Figure 1.

Data collection tools Data were collected by The Patient Information Form, Rheumatoid Arthritis Quality of Life Scale, the Health Assessment Questionnaire, and the Hospital Anxiety Depression Scale.

Patient Information Form: Our study was developed by researchers in line with a literature review on the subject. (Bozbas \& Gurer, 2018; Fall et al., 2013; Moghadam et al., 2018; Neto et al., 2009). The form consisted of eight questions about sociodemographic characteristics (age, marital status, education, etc.), clinical diagnosis, treatment of RA, concomitant chronic disease, and deformity affected by arthritis.

Rheumatoid Arthritis Patient Education Booklet: The content of the booklet was prepared by researchers in line with the literature. (arthritis.org; Moghadam et al., 2018; nras.org.uk; Rahim \& Cheng, 2018). The education topics included description, symptoms, and signs of RA, diagnostic methods, treatment choices, information on medications, RA in pregnancy, disease management information, nutritional recommendations, emotional health, and support in daily living.

Data collection Patients were interviewed twice, at baseline and at the 3rd month. All forms were applied to the patients in the intervention and control groups at baseline. The patients were assigned to the intervention group at random and participated in a one-to-one training program consisting of a 30-min onset session. The Rheumatoid Arthritis Patient Education Booklet prepared by the researchers was administered to patients in the intervention group during education. The inpatients were given one-to-one training in the patient's room during quiet periods. The outpatients were trained in the outpatient clinic, as tis was considered a suitable venue. In the 3rd month, all forms were applied again to the patients in the intervention group, and the same forms were applied to the untrained patients in the control group. The application of the forms took approximately 15 min, and the interviews were conducted face-to-face with the patients.

Data analysis Data were analyzed using IBM SPSS 20.0 program. Socio-demographic data were analyzed using the mean, standard deviation, and frequency. The Mann-Whitney U paired-group test was used to compare results that did not show a normal distribution. The Fisher's exact test, Pearson chi-square test, and continuity correction test were used. The Wilcoxon signed-rank test was used for the paired comparisons in the comparison of qualitative data. The significance level was set at p < 0.05.

Ethical considerations A University Research Ethics Committee was confirmed the study protocol, which adhered to the Helsinki Declaration (Approval number: 2018/344). Before taking part in the study, all of the patients signed consent forms. Participants were informed that their personal information and privacy would be protected. Patients who did not want to continue to participate in the study were free to leave the study at any stage.
