Do Text Message Reminders Increase Preoperative Exercise in Obesity Surgery Candidates?

Phase 3

Completed

• Conditions: Perioperative Care; Bariatric Surgery; Obesity
• Interventions: Behavioral: Daily text message reminders

• Registration Number: NCT01607177
• Lead Sponsor: University of Auckland, New Zealand

Brief Summary

Preoperative exercise has been shown to improve physiological and functional capacity in patients undergoing abdominal surgery to prepare them for the stress of surgery. Patients undergoing bariatric surgery are advised to partake in regular preoperative exercise. In the setting of bariatric surgery, as well as preparing patients for the stress of surgery, it is also thought to increase the likelihood that they will exercise postoperatively. However, compliance to this advice is extremely low. Text-message interventions have been shown to improve compliance to other lifestyle interventions. The investigators will compare the rate of compliance to preoperative exercise prior to bariatric surgery in patients who receive a daily text message to those who do not. The investigators will also compare weight loss.

Arm && Interventions

Group	Intervention	Description
Text message group	Daily text message reminders	Patients randomised to this group will receive daily text message reminders used to motivate them to exercise in the preoperative period. They will also receive an exercise information sheet to complement the text messages.

Primary Outcome Measures

Name	Time	Method
Proportion of patients partaking in the minimum recommended amount of weekly physical activity	6 weeks post recruitment	\>450 METmins per week of physical activity as measured by the internationally and locally validated IPAQ questionnaire.

Secondary Outcome Measures

Name	Time	Method
Postoperative Physical Activity	6 weeks postoperatively	Quantity of physical acitivty will be measured as METmins per week as measured by the IPAQ questionnaire
Functional capacity	Baseline and 6 weeks post recuitment (preoperatively)	Measured using the 6 minute walk test
Length of Hospital Stay	As assessed at day of discharge	Total number of days spent in hospital following their operation
Short term weight loss	Out to 6 months postoperatively	Postoperative weight loss as measured by percentage of excess weight loss
Perioperative complications	Out to 30 days postoperatively	Prospectively recorded postoperative complications graded according the Clavien-Dindo classification system
