About

An interventional prospective study on 200 bariatric surgery candidates from the Assuta Medical Center (AMC). The first 100 patients will be assigned to the control group and the later 100 patients will be assigned to the experimental group. All the participants will receive standard care, and only those participants who will assigned to the experimental group will be asked to watch a videotaped lecture of 30 minutes 1-2 weeks prior to the surgery date. The videotaped lecture will include information and guidelines of bariatric surgery preparation. All participants will complete Bariatric surgery knowledge questionnaire and The state-trait anxiety inventory (STAI) questionnaire at the bariatric committee and once again at the pre-surgery clinic which take place 1-10 days pre-surgery.In addition, 20 participants will be recruited to a pilot study for the validation of the Bariatric surgery knowledge questionnaire.

Full description

Only few studies have investigated anxiety level, bariatric surgery and nutrition knowledge and weight loss expectations prior to bariatric surgery. No studies have been published on how preparation lectures prior to bariatric surgery impact on anxiety level and on patients' knowledge. A better preparation process prior to the bariatric surgery may have an impact on higher success rates of bariatric surgeries.

Our study is an interventional prospective study on 200 bariatric surgery candidates from the Assuta Medical Center (AMC). The first 100 patients will be assigned to the control group and the later 100 patients will be assigned to the experimental group. All the participants will receive standard care, and only those participants who will assigned to the experimental group will be asked to watch a videotaped lecture of 30 minutes 1-2 weeks prior to the surgery date. The videotaped lecture will include information and guidelines of bariatric surgery preparation. Topics includes: types of surgeries, preparation to the hospitalization process and to the surgery (e.g. what to expect, personal equipment needs, description of the surgery admission process, etc.), dietary guidelines pre- and post-surgery (e.g. low carb diet 2-3 week prior to the surgery, post-surgery diet progression, techniques of eating and drinking, recommended dietary supplements), recommendation and tips for long term surgery success (e.g. definition of weight loss expectations, physiological, nutritional and life-style strategies for long-term weight loss). All participants will complete Bariatric surgery knowledge questionnaire and The state-trait anxiety inventory (STAI) questionnaire at the bariatric committee and once again at the pre-surgery clinic which take place 1-10 days pre-surgery. In addition, 20 participants be recruited to a pilot study for the validation of the Bariatric surgery knowledge questionnaire.
