NOVasure EXpierences (NOVEX)

Procedure: Subjects will be recruited from the outpatient clinic from Máxima Medical Center Eindhoven and Veldhoven. Patients presenting with heavy menstrual bleeding and scheduled for endometrial ablation (Novasure) between March 2022 and April 2024 were approached for study participation either by email, phone call, or in-person during their clinic visit. Upon expressing interest, patients will be provided with detailed information about the study and asked to sign an informed consent form. Patients were randomized in an alternating order and 1:1 ratio. Subsequently, after randomization, the participants will be sent a secure email containing the link to the educational videos. Patients will watch the educational videos 1-7 days before their Novasure treatment.On the day of treatment, before undergoing the Novasure procedure, patients will complete the Visual Analogue Scale for Anxiety (VAS-A) and Amsterdam Preoperative Anxiety and Information Scale (APAIS). Two days post-treatment, the participants will receive a questionnaire via email through Research Manager. This questionnaire will encompass inquiries regarding demographics, patient characteristics, treatment-related positive and negative factors, improvement of care, and patient satisfaction. Two groups will complete the questionnaires: one group that viewed an educational video before Novasure treatment and a control group that did not view the video. Both groups receive the same treatment (Novasure), with the only difference being the addition of the educational video as part of pre-procedural preparation, as both groups receive information from the gynecologist about the procedure. Additionally, patients have access to further information online or in brochures. Therefore, conducting this study raises no ethical concerns. The researchers conducted a power calculation using G\*Power 3 to determine the sample size for the questionnaire research. Based on this calculation, considering a pilot study and prior research suggesting a minimum of 12 patients per group, the aim was to include 16 patients per group (total 32 patients). Data will be analyzed by an intention-to-treat analysis. Frequencies and percentages for general characteristics will be determined. The mean plus standard deviation of VAS-A, APAIS anxiety and need to obtain information scores, and other scale variables will be calculated. Mann-Whitney U tests will be used to assess group differences for VAS-A, APAIS, and scale variables. A p\<0.05 will be considered statistically significant. Descriptive statistics will be used to compute frequencies and corresponding percentages for nominal and ordinal variables.
