Study information
Scientific title
Positive Online Weight Reduction Study (POWeR): a randomised multicentre interventional prevention/process of care trial
Acronym
POWeR
Study hypothesis
Obesity is a major and rapidly rising public health threat. Recent NICE guidelines provide recommendations to implement lifestyle changes (diet and exercise) supported by behavioural techniques. Unfortunately, an average practice will have more than 1000 patients with obesity, and most practice staff have neither the training nor the time to implement intensive obesity management programmes based on 1:1 counselling, or even group counselling, to cope with such numbers. The problem will become worse as the obesity epidemic progresses. By providing an intervention which requires fewer resources for training and for intervention this study will allow a much greater group of patients to benefit both locally and nationally.
We have developed written behavioural manuals for both patient and practitioner. This study will create a less resource intensive intervention to support behavioural change by converting these materials into web format, taking advantage of a grant to our group which supports the development of generic web programming for behavioural interventions. After materials have been converted to web format, and are acceptable to patients and practitioners, we will then explore the impact of different levels of nurse support required to achieve effective weight change.

Condition
Topic: Primary Care Research Network for England; Subtopic: Not Assigned; Disease: All Diseases
Intervention
Phase 1:
Study 1: In-depth interviews will be carried out with up to 30 patients from 3 - 4 GP practices to elicit views of the intervention materials (including reactions to content and usability).
Study 2: Up to 5 focus groups will be held for health professionals with practice nurses and GPs from 10 - 20 practices. Participants will be invited to use the training materials and patient website prior to taking part in the focus group to stimulate discussion of the issues relating to content, format and feasibility.
Phase 2:
Pilot RCT: Patients will be offered:
1. Web access and email support
2. Minimal face to face support
3. Intensive face to face visits
4. Normal care
GP records will be reviewed for cost-effectiveness.
