Summary and Purpose

1. The report attached at Appendix One sets out the progress made with the work programme of the Committee agreed by members in 2007/08 and the draft programme for 2008/09.

2. The work programme proposed takes account of the following:

· Issues raised by Members over the last year and discussed in Committee.


· Topics identified by key partners (Patient and Public Involvement Forums, NHS organisation and District Councils).


· National policy developments that will have an impact on the health of local people.


· Local issues that will have an impact on the provision of health services to people living in Hampshire.

3. The approach outlined builds on and consolidates previous work undertaken by the Committee, taking account of the feedback received from organisations that work alongside the Committee. This provides a flexible framework through which the Committee can give informed comment and feedback on a range of issues affecting the health of local people and allows the Committee to respond in a timely manner to proposals from the NHS to substantially vary health care provision. This enables the Committee to take action when opportunities to improve local service delivery are identified.

4. The work programme for the coming year has therefore been based on three core work strands, underpinned by a commitment to building effective working relationships and communications with our partner organisations:

· Reviews of health services - thematic cross cutting reviews of health services in the area of the Committee. The review programme focuses on specific topics of interest or concern to the Committee and identifies opportunities for improvement.


· Health Inquiries - provides a route through which our partner organisations can raise issues with the Committee. This allows action to be initiated speedily, without resort to a formal review and enables good practice to be drawn to the attention of members.


· Substantial variations or developments - as a statutory consultee of the NHS the Committee will respond to proposals that will have a significant impact on service delivery to people living in Hampshire. If the proposal affects services outside the area of the Committee this may include statutory joint arrangements with other health overview and scrutiny Committees.

5. To make the best use of the resources available to the Committee, issues raised with the Committee have been evaluated to ensure that they do not duplicate other scrutiny or review activities and have the potential to influence or improve the topic under consideration. The four criteria used in this process are included in the report.

6. The report provides the context within which the Committee is able to influence and improve the delivery of health services to people living in Hampshire. As such it supports the delivery of the aim of maximising wellbeing as set out in the Corporate Strategy.

Recommendation:

7. The Committee approves the annual report for 2007/08 and the draft work programme for 2008.09.

Health Overview and Scrutiny Committee

Report on Progress Spring 2007 to Spring 2008

Introduction from the Chairman

This report provides an update on the work of the Health Overview and Scrutiny Committee (HOSC) in 2007/08. I would like to thank Committee members and officers for their commitment and hard work during another busy year. As the organisational changes in the NHS have begun to stabilise, distractions of re-organisation are being replaced with renewed focus on health planning, commissioning and service delivery.

The year has seen most NHS organisations achieve stronger financial positions, although pressures to control and achieve cost savings where possible will continue to challenge commissioners to identify efficient, good value providers of health services.

At the end of March this year, Patient and Public Involvement Forums (P&PIFs) will cease to exist. Their place will be taken by Local Involvement Networks (LINks), however we still lack a clear indication from central Government about how they will work. I would like to commend members of P&PIFs in Hampshire for their role in bringing issues to the Committee over this last and previous years. P&PIFs have played a valuable part in supporting the work of HOSCs.

I continue to have monthly meetings with the Chief Executive of the SHA Board, attend board meetings of Hampshire PCT and maintain active contact with other NHS organisations in the County. This engagement with the NHS is an essential part of building and strengthening a productive working relationship with health partners.

In addition to my role as Chairman of the Hampshire HOSC, I am also Chairman of the Hampshire, Southampton, Portsmouth and Isle of Wight Health Scrutiny Joint Committee and the South Central Health Overview and Scrutiny Committees which comprise a network of HOSCs from all local authority areas served by the South Central SHA. These committees allow issues of common concern to be discussed and sometimes addressed more effectively than by individual HOSCs.

The West Sussex Health Overview and Scrutiny Joint Committee, which included Southeast Hampshire HOSC representation, has worked conscientiously to represent to West Sussex PCT concerns about their Fit for the Future proposals which could affect health services in South East Hampshire.

We have continued to monitor progress against the recommendations of the Review of Care at End of Life, which is being taken forward by a steering group jointly led between the PCT and Adult Services. We will continue to have an interest in the development of this work, as well as with out-of-hours services, the responsibility for which now rests with the PCT.

In October, on behalf of the Hampshire, Southampton, Portsmouth and Isle of Wight Health Scrutiny Joint Committee we were pleased to run a Mental Health Workshop on the Mental Health Act 2007 and its implication for health services. This meeting was well attended and appreciated by participants.

Following from the interim Lord Darzi review, the PCT is considering the development of a GP Health Centre to improve access to general practice; the Committee will be providing a response to this proposal.

Access to dental services has continued to be a challenge for the NHS and is an issue in which we will have an interest. Changes in performance targets for the Ambulance Service will necessitate further improvements and efficient solutions, we will also be monitoring progress in this area.

As ever, the Committee will be very vigilant about `temporary' closures and the quality of engagement with the public in service planning and change.

The report sets out:

· Local progress with health scrutiny (Section 1)

· The achievements of the Committee over the last year, including joint scrutiny arrangements (Section 2)

· The outline work programme for 2008/09 (Section 3)

Cllr Dr Raymond Ellis, C.Chem FRCS

Chairman, Health Overview and Scrutiny Committee

Section 1: Local Progress with Health Scrutiny

Health Overview and Scrutiny is a statutory responsibility for local government. It is intended to ensure that decisions about health services are taken with due regard to the people affected. The legislative framework within which the Committee functions, allows Members to consider any aspect of health that affects the population Hampshire. It also places very specific duties on the NHS with regard to consultation, information and responses to any recommendations made by the Committee.

The Committee is a statutory consultee on any substantial change being considered by the NHS and has the power to refer contested decisions about health services to the Secretary of State for Health or to Monitor in the case of Foundation Trusts. A summary of the main powers of the Committee, and the duties placed on the NHS, is attached at Appendix One.

Arrangements are in place to allow these powers to be delegated to allow for specific proposals affecting the health of local people to be considered by a joint committee or, in exceptional circumstances, by another scrutiny committee set up by local government.

As its role has evolved, the Committee has been mindful that it is not the only, or even the main form of engagement between the NHS and local government. Services are increasingly commissioned in partnership across health and social care and this is likely to increase as new policy initiatives are implemented.

Patient and Public Involvement Forums (P&PIFs) and District Councils have each had a role to play in shaping the Committee's understanding of local issues, providing a rich source of intelligence about issues relating to health and health services. Similarly, the Committee needs to have a constructive working relationship with internal service providers, the Executive, the Cabinet and other scrutiny functions undertaken by local authorities and public agencies.

From April 2008 Patient and Public Involvement Forums will cease to exist. Local Involvement Networks (LINks) will become the new body responsible for representing communities and providing opportunities for them to influence the development of the health and social care bodies that service their areas. LINks will have the right to visit some services, and make reports and recommendations to the Committee, partnerships such as the Local Strategic Partnership, and commissioners of health and social care.

Health, and health services in Hampshire are complex, with different priorities in different communities. In order to improve working relationships between Health and Social care, Hampshire PCT has developed three operational areas to fit with the County Council's three social care areas. These arrangements help strengthen local influence on services provided in each area.

The network of working relationships that has now been established demonstrates the commitment of the Committee to ensure that, to the fullest extent possible, it is the local community that has the greatest influence on the development of health services in a particular area. This local influence has been a recurrent theme as the work programme has rolled forward and remains a central feature of the work of the Committee.

Emphasis has therefore been focused on ensuring that programmes are effectively targeted to enable the scrutiny process to be both credible and influential. The approach to health scrutiny adopted by the Committee therefore places emphasis on ways of working that are:

· Challenging but not confrontational

· Evidence based

· Able to improve service delivery

The role of the Committee as a `critical friend' has been established, and relationships with partner organisations, have continued to develop; the relationship with Hampshire PCT has been particularly constructive. The drive to reduce costs in the system will continue to put pressure on local health services to find savings; the potential impact these may have on local people makes it vital that the Committee maintains a constructive dialogue with these organisations and other partners.

The forward work programme of the Committee set out in Section 3 of this report has therefore been developed in discussion with P&PIFs, District Councils and NHS organisations in Hampshire. It takes account of the work that the Committee must do, specifically:

· Respond to proposals to substantially vary NHS services in the area of the Committee

· Manage referrals from P&PIFs (and other partner organisations)

In addition, it identifies issues that may benefit from a more in-depth thematic review. To make the best use of the resources available to the Committee the following four criteria have been developed to guide Members when selecting topics for review:

· Capacity to influence and improve the service under consideration

· Timeliness and relevance to local health services

· Issues not under consideration elsewhere

· Issues not subject to other scrutiny or performance monitoring activities

The approach to health scrutiny adopted by the Committee and described in the following work strands is drawn from national guidance and discussions with partner organisations. A summary of the relevant sections of the Guidance is included at Appendix Two.

The Work Programme of the Committee draws together four main work strands:

· Relationships and Communication: From its inception the Committee has been aware of the need to be able to work in partnership with other agencies when discharging its responsibilities in relation to health overview and scrutiny. Experience reinforces the importance attached by the Committee to ensuring that an extensive network of key contacts is built and maintained to support a challenging but constructive approach to health overview and scrutiny.

· Proposals to vary or develop NHS services: Any proposals for service change from the NHS should be discussed with the Committee at an early stage, in order to agree whether or not the proposal is considered substantial. In determining if a proposal is substantial, the Committee considers the impact of the change on patients, carers, and the public who use, or have the potential to use a service.

· Reviews of Health Services: This strand of work was identified by the Committee to provide thematic cross boundary reviews of health services. These consider specific areas or services that are of interest or concern to the Committee and identify opportunities for improvement.

· Health Inquiries: The `health inquiries' work strand was designed to provide the Committee and partner organisations with a route through which issues could be raised and acted on outside the review process. This mechanism allows the Committee to maximise opportunities to influence and improve health services without recourse to a full review as well as providing a means by which developments in health can be drawn to the attention of the Committee.

Section 2: The Achievements of the Health Overview and Scrutiny Committee in 2007/08

The Committee continues to provide an active and constructive influence in the planning and delivery of health services for the people of Hampshire. The Committee maintains its commitment to taking an independent, impartial approach to considering evidence and ensuring that the views of all relevant stakeholders are taken into account.

Relationships and Communication

Constructive and open relationships with NHS and other partner organisations are essential to the ongoing work of the Committee and to maintaining trust. After an extended period of financial challenges and extensive re-organisation in Health organisations, 2007 has seen these bodies adjust internally to meet the commissioning and strategic challenges in delivering health care in the county. Good communication between the HOSC, Hampshire PCT and South Central SHA is well established, and should continue to be productive with improved structural stability.

Members receive presentations and reports at HOSC meetings that keeps the Committee well informed about health issues and plans that affect the people of Hampshire. Examples include proposals for the development of maternity services in the South East and West of Hampshire, and the actions taken by acute trusts to tackle the incidence of c. difficile.

The HOSC values and continues to build on its working relationships with district councils. Meetings with each district are held during the year, and the HOSC includes representation from the districts via The Hampshire and Isle of Wight Local Government Association.

In addition, the Chairman of the Hampshire P&PIF, and the Chairmen of the Portsmouth, Southampton and Isle of Wight HOSCs are formal observers at HOSC meetings. New arrangements will be put in place to replace P&PIF representation when the LINk is setup in Hampshire.

Referrals from stakeholders, continue to play an important role in informing the Committee of emerging issues. This feedback is an important element in confirming that NHS bodies have engaged properly with patients and relatives or carers when considering service change.

In the context of new Local Area Agreements, increased joint commissioning arrangements and joint or integrated delivery of health and social care, the development of effective working relationships with an increasing wide range of stakeholders will be essential for the Committee.

Proposals to Develop or Vary NHS Services

Proposals to develop or vary NHS services have continued to come to the HOSC throughout he year. Members can be aaaalerted to forthcoming proposals to change health service provision All proposals for varying NHS services are considered by the Committee and any associated reports or comments are included with agenda papers to ensure members are properly informed about proposals to change health service provision.

Reviews of Health Services

Care at End of Life: the report for this review was brought to the Committee in January 2007. Members have maintained an active interest in this importance aspect of care. In October 2007, the Committee met specifically to follow up on the recommendations in the report and to determine how work was being taken forward. Members were told of the establishment of the Care at End of Life Review Implementation Plan Project Steering Group. This steering group is jointly led by Hampshire PCT and Adult Services.

Out of Hours: in March 2006 the Committee reviewed the Hampshire Strategic Health Authority's strategy for the development of OOH services in Hampshire. At that time Hampshire had 7 PCTs and there were 5 separate arrangements in place to provide OOH care. However, during 2006 the SHA became part of South Central SHA, and in October the 7 PCTs became Hampshire PCT. Since October 2006 the PCT has had responsibility for the strategy and development of OOH care in Hampshire.

The Committee continues to have an interest in OOH services, the plans for their development, commissioning and implementation. Members expect to be updated by the PCT on developments through 2007 at the HOSC meeting in May 2008.

Public Health and Wellbeing: the Committee published in March 2006 a comparative review of progress made by the NHS and local authorities in Hampshire against the Health Improvement Foundations for LAAs and the `overarching priorities' of the Department of Health white paper, `Choosing Health: making healthy choices easier', 2004.

Following a year of organisational transformations in the NHS in Hampshire, Jean Bradlow was appointed in March 2007 as Director of Public Health, a joint appointment between Hampshire PCT and the County Council. Whilst the Committee maintains an interest in Public Health, because of the cross-cutting nature of Public Health and Wellbeing, it expects that issues may be taken forward as appropriate by relevant committees.

Joint Committees

Joint Health Overview and Scrutiny Committees may be permanent, where because NHS organisations characteristically provide services to more than one HOSC area, standing joint committees consider issues of common interest. In addition, joint committees may be set up solely to undertake scrutiny of a specific issue of common concern to more than one HOSC.

Hampshire, Southampton, Portsmouth and Isle of Wight Health Scrutiny Joint Committee is a permanent committee under the chairmanship of Cllr Dr Ray Ellis. Over the last year, the following issues have been considered:

· The Hampshire Partnership Trust proposal to achieve foundation trust status

· Services for people with learning disability in South East Hampshire, including the proposed closure of a respite unit

· Maternity Services in South East Hampshire

· Joint Health Protocol adopted

· Ambulance Service response times

· Preparing for Local Involvement Networks (LINks)

· Southampton University Hospitals Trust proposal to achieve foundation trust status

· Isle of Wight Residential Services for Adults

· Specialist Palliative Care Services in South East Hampshire: potential withdrawal of commissioning arrangements by Portsmouth City PCT

Mental Health Workshop): in addition to issues considered by this joint committee, it also organised a mental health workshop, providing opportunity for stakeholders to consider with partners and fellow stakeholders the recently introduced Mental Health Act 2007 and its implications for commissioning and providing health and care services.

The South Central Health Overview and Scrutiny Committee is a regular meeting of HOSC chairmen and officers for the South Central area under the chairmanship of Cllr Dr Ray Ellis. Over the last year, the following issues have been considered:

· Patient and Public Involvement Forums and Local Involvement Networks (LINks)

· Community Hospitals - SHA strategy

· Synopsis of Areas Performance across South Central area

· Our NHS our Future: Darzi Review

· County Hospitals and Community Services - SHA

· South Central Ambulance Service

· Specialist Commissioning - proposals by SHA)

The West Sussex Health Overview and Scrutiny Joint Committee was established to examine the proposals by West Sussex and Brighton and Hove City PCTs. Of particular concern was the proposed re-configuration of acute health services and Maternity Services. The joint committee has met bi-weekly for several months to consider and pursue issues of concern, and continues to do so, pending the final decision of the Health bodies. Issues of concern have included:

· Financial modelling

· Lack of information about maternity services

· Location of accident and emergency services

· Maternity Services

Section 3: Outline Work Programme for 2008/09

Building on feedback from partner organisations, Hampshire Action Teams and Members, the HOSC will continue to use the four work strands identified to form the work programme for the coming year.

Relationships and Communication

The Committee will continue to engage actively with partner organisations across Hampshire, and one-to-one meetings as appropriate.

The Committee will develop links with the Local Involvement Network and other partners who are in a position to comment on health provision and the effectiveness of joint health and social care arrangements. It is anticipated that increasingly Hampshire Action Teams will provide intelligence about health issues in their areas.

Proposals to vary or develop NHS services

The Committee will continue to use the Framework for Assessing Service Change. This documentation has been very effective in helping to clarify and evaluate the extent and implications of proposals of NHS organisations to vary or develop services.

The Committee will continue to be informed by proposed changes by NHS bodies to vary or change services and will respond within agreed timescales.

Reviews of Health Services

The Committee will continue to take an active interest in progress against the HOSC's Review recommendations, and developments in Care at End of Life in Hampshire. The work is being taken forward by the Review Implementation Project Steering Group, a groups that is jointly led between Hampshire PCT and Adult Services.

The Committee will also resume an active interest in the planning and delivery of Out-of-Hours care. Responsibility for strategy and planning rests with Hampshire PCT.

Health Inquiries

The Committee will continue to receive information on, and initiate action in response to, issues raised by Members and partners.

Particular issues for further consideration and action during 2008/09 may include:

· Access to dentistry

· South Central Ambulance Service performance

Appendix Two

Hampshire County Council

Health Overview and Scrutiny Committee

Summary of Key Expectations in the Department of Health Overview and Scrutiny of Health - Guidance

In the Annual Report, useful information is provided about the responsibilities of Members of HOSCs. The Annual Report also notes that interaction between the NHS and its local authority and other partners happens at different levels and in different ways. Local experience and intelligence about how the often complex arrangements work for patients, can come from key statutory partners or independent partners such as P&PIFs (LINks from 1 April 2008)

The busyness and complexity of the NHS, new national initiatives, and local patient experience can sometimes distract from reflection on the fundamental expectations of Government of the Health Overview and Scrutiny role. Some of these expectations are noted below as a reminder as to why the Committee places importance on:

· Relationship building

· Processes for effective scrutiny

· Strategic scrutiny

· Operational scrutiny

Relationship building

In the Department of Health's, Overview and Scrutiny of Health - Guidance, it was clearly indicated that they expected Health Overview and Scrutiny Committees to work in a challenging, complex environment; "The Government's intention is that the focus of health scrutiny is on health improvement, bringing together the responsibilities of local authorities to promote social, environmental and economic well-being and the power to scrutinise local services provided and commissioned by the NHS". One of the key requirements of the Committee must be to establish and build a network of positive working relationships that will make it possible to achieve the broad aim of `health improvement' as indicated in the Guidance. It is for this reason that the Annual Report explicitly comments on `relationship building' as a key area of the Committee's work.

Processes for effective scrutiny

The Guidance implies its concern that HOSCs should have effective processes for scrutinising issues that are brought to it, for example, it says, "...if the process (of scrutiny) is aggressive, or relies on opinion rather than evidence, it is unlikely to lead to positive or sustainable improvement." It also emphasises that scrutiny must be based on firm foundations, "Members of scrutiny committees need to take a constructive but challenging approach to the role, bringing together evidence and people's experience to identify priority issues and drive forward improvement." The Annual Reports makes clear that establishing and building effective processes for the scrutiny function is another key responsibility of the Committee.

Strategic scrutiny

The Guidance document is helpful in explaining the scope of health scrutiny when it says, "The powers of overview and scrutiny of the NHS enable committees to review any matter relating to the planning, provision and operation of health services in the area of its local authority. It is recommended that best use of these powers will depend on committees scrutinising a health issue, system or economy, not just services provided...". The wider context of local service delivery is therefore of significant interest. Examples of this aspect of the Committee's work are to be found in its raising questions about national funding, or in its Hampshire-wide reviews of health issues.

Operational scrutiny

The Government Guidance also gives due weight to Health Scrutiny's role with respect to local service delivery, "Committees are best placed to concentrate on ensuring that health services address the needs of local communities and that local health and health-related issues are being tackled jointly across local agencies." The sections on Proposals to vary or develop NHS Services, and Health Inquiries in the Annual Report contain examples of this aspect of the Committee's work.

Implicit in the Guidance is the expectation that because, "...the focus of health scrutiny is on health improvement", the remit will inevitably include those areas, sometimes associated with `wellbeing' that can be determinants of health, "...the solutions to matters that are scrutinised, may therefore be the responsibility of a number of stakeholders. In this light the power to scrutinise health services should be seen and used in the wider context of the local authority role of community leadership and of other initiatives to promote and facilitate improvement."
