Overview

To help the development of public health guidance on obese adults – lifestyle weight management NICE is calling for evidence for an evidence review that focuses on best practice, barriers and facilitators to delivery, training and evaluation. We are particularly interested in any relevant unpublished, commercial or other information that we would not be able to identify through a search of databases (for example, information on referral or commissioning processes or process reports).  This includes information on:

1. What are the beliefs and attitudes that affect take-up of weight loss programmes and adherence to them once people have started the programme?  How do these beliefs and attitudes vary in the population, for example by ethnic or other population subgroup? 
2. How are weight loss services distributed across the country?  What features of the services determine where, when, how and to whom they are provided?  How do services interact with other elements of the public health system to facilitate or hinder the provision and use of services?
3. What can primary care providers say or do that affects the likelihood of patients taking up referral to and adhering to weight loss programmes? 
4. What beliefs and attitudes do potential referrers to weight loss services hold about such services?
5. How do referral systems vary across the country and how do these characteristics determine uptake and adherence to weight loss programmes?
6. What knowledge and skills are required by providers of weight loss services?
7. What is the best way to commission and monitor weight loss services?

The closing date for submissions is 1 February 2013.

Background

The National Institute for Health and Clinical Excellence (NICE) has been asked by the Department of Health to develop public health guidance on Managing overweight and obesity in adults – lifestyle weight management services.

The scope for this work can be found on the Managing overweight and obesity in adults webpage.

Since publication of the NICE guidance on obesity (2006), more evidence is available on the effectiveness of non-clinical, lifestyle-based weight management programmes for adults. As a result, it may be possible to refine and clarify best practice for both self-help and referral schemes. New evidence may also support the development of guidance on how to commission lifestyle weight management services. This might include, for example, whether a minimum number of sessions are required to ensure cost effectiveness, or the best ways to provide ongoing support. This guidance will provide recommendations for good practice, based on the best available evidence of effectiveness, including cost effectiveness. It is aimed at commissioners, health professionals and providers of weight management programmes. It will also be of interest to overweight and obese adults and other members of the public.

For the purpose of this guidance, multi-component lifestyle weight management approaches are defined as those which focus on adults who are overweight or obese and aim to change someone’s behaviour to reduce their energy intake and make them more physically active. It may include weight management programmes, courses or clubs that:

• accept adults through self-referral or referral from a health practitioner
• are provided by the public, private or voluntary sector
• are based in the community, workplaces, primary care or online.

Call for evidence

This is the second call for evidence for this guidance. The closing date for submissions is 1 February 2013. Please do not re-submit information sent in to the first call for evidence. Any submitted evidence will contribute to the evidence reviews that are being commissioned as part of the development of this guidance. We are particularly interested in receiving unpublished, commercial or other data that we would not be able to identify through a search of databases. We are able to accept data in confidence (see below). Please note that for published data, we are interested in data published from 1995 onwards.

We would like data that can contribute to any the key questions in the scope for this work, although we are particularly interested in information on the barriers to providing/commissioning weight management services and referral systems. This includes:

1. What are the beliefs and attitudes that affect take-up of weight loss programmes and adherence to them once people have started the programme?  How do these beliefs and attitudes vary in the population, for example by ethnic or other population subgroup? 
2. How are weight loss services distributed across the country?  What features of the services determine where, when, how and to whom they are provided?  How do services interact with other elements of the public health system to facilitate or hinder the provision and use of services?
3. What can primary care providers say or do that affects the likelihood of patients taking up referral to and adhering to weight loss programmes? 
4. What beliefs and attitudes do potential referrers to weight loss services hold about such services?
5. How do referral systems vary across the country and how do these characteristics determine uptake and adherence to weight loss programmes?
6. What knowledge and skills are required by providers of weight loss services?
7. What is the best way to commission and monitor weight loss services?

We are interested in a broad range of different types of information, including local process and evaluation reports, measures of service reach and sustainability, finance reports, the pricing of weight management programmes alongside more traditional quantitative evidence (such as pilots or observational studies) and qualitative evidence (such as those which consider participant satisfaction or reasons for drop out). We are particularly interested in evidence that may help to better promote equality of opportunity relating to age, disability, gender, gender identity, ethnicity, religion and belief sexual orientation or socio-economic status.

With finance data, we are interested in the cost to individuals or the LA/NHS of taking part in a weight management programme, including discounts by volume and for longer contracts. We are unlikely to be interested in the profits or losses to a commercial company.

Submitting evidence

If possible, it would be helpful if you could identify which (if any) of the questions above the information you are submitting relates to.

Annex 1

The use of 'commercial in confidence' and 'academic in confidence' data in the development of public health guidance: statement of principle

1. NICE is under obligations of transparency and fairness to all stakeholders, among others, in the development of its guidance

2. The rights of the owners of the data provided to NICE must be respected.

Definitions

3. Commercial in confidence information is information provided in confidence relating to the commercial interests of the owner of the information

4. Academic in confidence information is information provided in confidence in circumstances where disclosure could prejudice future publication of the information in a scientific publication. It would be expected that any information marked as academic in confidence is going to be published at some stage and that a timeline for publication can be given.

Submission of data

5. The amount of information submitted on an 'in confidence' basis should be kept to a minimum. The whole submission should not be marked as confidential. It is likely to be unacceptable to mark complete sections as confidential.

6. Only information that is genuinely confidential, such as actual numbers, should be marked as in confidence. NICE will only treat information in confidence if the material is in fact either 'commercial in confidence' or 'academic in confidence'.

7. When marking data as confidential, organisations should indicate if this status will apply at the time NICE anticipates publication/presentation of the data. The last opportunity for organisations to review the confidential status of information is during the consultation on the draft guidance and its supporting evidence.

8. For all unpublished data submitted as 'academic or commercial in confidence' the minimum that should be made available for release is that which normally would be included in a CONSORT (or PRISMA) compliant abstract and be suitable for public disclosure. An equivalent approach is required for all data and studies which underpin and are included in economic analyses and models, and for the economic model included in the submission if that is marked 'academic or commercial in confidence'.

Presentation of data at PHAC or PDG meetings

9. Data that contributes to evidence of effectiveness and cost effectiveness can be presented to a PDG meeting or to a PHAC meeting provided the information is factual, accurate and not misleading.

10. 'Academic in confidence' information may be presented during the PDG and PHAC meetings, even if the meetings are conducted in public. However, the data owner retains the right to make a final decision in relation to the release of confidential information into the public domain

11. The data owner retains the responsibility for the release of 'commercial in confidence' data into the public domain. With the exception of presentation of data at PDG or PHAC meetings, the data owner retains the right to make a final decision in relation to the release of confidential information into the public domain.

Publication of data

12. In circumstances where NICE wishes to publish data regarded by the data owner as academic or commercial in confidence, both NICE and the data owner will negotiate in good faith to seek to find a mutually acceptable solution, recognising the need for NICE to support its recommendations with evidence and the data owner’s right to publication. However the data owner retains the right to make a final decision in relation to the release of confidential information into the public domain.

Economic models

13. NICE will normally disclose in full economic models provided by manufacturers/sponsors to NICE as part of an submission of evidence, together with the data on which such models are based. Exceptionally, data within a model can be treated as confidential if they contain or make practical the reverse engineering of confidential data inputs which are credibly specified as confidential by the organisation or company.

14. Model structures will not be accepted as confidential information, and by submitting a model the manufacturers/sponsor will be taken to have agreed that the model structure may be put into the public domain.

Disclosure of confidential data

15. NICE is challenged that confidential information it has received should be released in the interests of fairness, during the guidance development process or otherwise, data owners must on request promptly reconsider whether it is in fact necessary to maintain confidentiality.

16. NICE does not intend to make repeated requests for a prima facie tenable claim of confidentiality to be abandoned or modified, and it will accept the data owner’s judgement in that regard.

17. NICE cannot 'second guess' the motives of a data owner. If a data owner would not agree to the specific request for disclosure made, but would agree to some more limited disclosure (for example to a "confidentiality club",) then it is asked itself to suggest the disclosure it would find acceptable, rather than wait for NICE to propose the specific formula it may have in mind and discuss and agree a potential solution with NICE.

18. If disclosure is not possible the data owner must be prepared to assert publicly that the information is considered to be confidential, and must submit evidence giving the justification for maintaining confidentiality in defence of NICE's maintenance of that confidentiality. In the absence of any such assertion and evidence, NICE shall be entitled to conclude that the information is no longer confidential.
