Effect of Mobilization Training Given to Hysterectomy Operation on Bottom Functions and Pain

This two-arm randomized controlled trial (RCT) was conducted in the women patients undergoing hysterectomy located in Edirne, between May 2022 and June 2023. During the intake, the women patients undergoing hysterectomy were informed about the goals and setup of the study and intervention, and assessed for eligibility by a brief standardized interview. The women patients undergoing hysterectomy who fulfilled our criteria received an information letter and informed consent form, as well as the baseline questionnaire. Those women patients undergoing hysterectomy that provided written informed consent for participation were included in the study. Assessments in both groups were performed before randomization (i.e., baseline) and directly after the intervention period.

Randomization: The women patients undergoing hysterectomy were randomly assigned to an education or control groups. A research assistant not actively involved in the design and data analysis of the study created a random distribution sequence and assigned participants to one of the two conditions (1:1 ratio).

Intervention:

Mobilization Training: A face-to-face "Patient Information Form" was applied to the training group in the first interview before the hysterectomy operation. The participants in the training group were given hysterectomy postoperative mobilization training by the researcher (B.K) using presentation and verbal information technique. A "Post-Operative Follow-up Chart" was given to the participants to fill in the 1st and 2nd postoperative days. The training group participants were followed up by the researcher on the 0th and 1st days after the operation in line with the mobilization training they received. The "Post-Operative Follow-up Chart" questioning the patients' mobilization times, distances, bowel functions and pain scores was filled in by the researcher in detail by face-to-face interview method. Mobilization time (minutes) and distance (meters) were evaluated by the patients and their relatives, and recorded on the chart, using the stopwatch and pedometer on the personal mobile phones of the patients.

Control Group: The women patients in the control group who underwent hysterectomy were informed that mobilization training would be performed after a postoperative 2-day waiting period. Meanwhile, no intervention was made except for any routine nursing care.

Measures: "Patient Information Form" and "Post-Operative Follow-up Chart" were used in the study. Patient Information Form: It was created by the researchers by scanning the literature and consists of a total of 18 questions, including 6 questions about the personal characteristics of the participants, 3 questions about the obstetric and surgical characteristics, and 9 questions about the postoperative results. Postoperative Follow-up Chart: It was created by the researchers by scanning the literature and consists of a 24-hour chart including the 0 and 1 postoperative day mobilization time, mobilization distance, pain score, gas and stool output time of the participants.

Sample size calculation for the primary research question was performed based on a pilot study. Tharwat et al. (2021), within the scope of the findings of their study named "Impact of Sugarless Chewing gum Versus Peppermint on First Bowel Movement after Cesarean Section: Randomized Controlled Trial", sample calculation was made by predicting the effect size of 0.6307060, 95% confidence level, and 80% power. Power analysis of the study was performed with G*POWER 3.1.9.7 (Power analysis statistical software) program (Faul et al., 2021). A total of 82 women with hysterectomy (Training group: 41 women, Control group: 41 women) constituted the sample.
