"Health care matters to all of us some of the time, public health matters to all of us all of the time“

C. Everett Koop

What is health?

What is health?

“A state of complete physical , mental and social well being and is not merely the absence of disease of infirmity.” (World Health Organisation, 1948) “The extent to which an individual or group is able to realise aspirations, satisfy needs and to change or cope with the environment “ (World Health Organisation, 1984)

What is Public Health?

• The science and art of preventing disease, prolonging life, and promoting health through the organised efforts of society

Acheson 1988 in the Public Health in England report

• Public health is concerned with improving the health of the population, rather than treating the diseases of individual patients.

Chief Medical Officer

Well-being?

For these purposes we will consider health and well-being to be the same thing

Public health

Focuses on the entire population even when they are not ill

Rather than

Individuals when they become ill

Therefore

Public health regards the community as its patient

The Faculty's Public Health Approach

• •

Is population based Emphasises collective responsibility for health, its protection and disease prevention

•

Recognises the key role of the state, linked to a concern for the underlying socio-economic and wider determinants of health, as well as disease

•

Emphasises partnerships with all those who contribute to the health of the population

Improvement of the Sewerage and Drainage of the Borough of Liverpool

struggling with Liverpool’s health problems

• Obituary: the health of Liverpool was so improved that

there was “no longer any occasion for the salary of a medical officer at £700 per year”

Who contributes to public health?

(even though it may not say so in their job description) • 3 main categories (CMO’s report) –

Professionals who spend some of their time in PH related work – teachers, other healthcare workers, other government officers, systems engineers

– –

Professionals who spend major part of their work in PH issues – health visitors, health promotion, information, EHO Specialists – strategic/senior level – ability to manage change and lead PH programmes Who else?

What does it involve?

• Assessment of health needs • Monitor health status of population • Programmes for risk reduction/screening • Communicable disease control • Planning health services • Evaluation of provision of health services • Manage and implement change • Work with other agencies to maximise health gain

How is PH organised?

• Department of Health (DH) • Strategic Health Authorities (SHA) • Primary Care Trusts (PCT) • Regional Public Health Groups (RPHG) • Local Authorities and Local Strategic Partnerships • Health Protection Agency (HPA) • Public Health Observatories • Faculty of Public Health (FPH)

Organisation of public health

FPH & UKPHR RPHG DH SHA PCT Other Government Departments Regional offices Local Authorities Voluntary agencies etc HPA HPU

3 main areas

Main functions

1. Health protection 2. Health and social care 3. Health improvement

1 Health protection

• Communicable disease control • Environmental health • Emergency planning • Disease and injury prevention

2 Health and social care

• Quality • Clinical effectiveness and efficiency • Clinical governance • Audit and evaluation • Service planning

3 Health improvement

• Inequalities • Lifestyles • Education/housing/employment/ environment – broader determinants of health

Link to inequalities – geographical variations

• A boy in Manchester can expect to live over 7 years less that a boy in Barnet • A girl in Manchester can expect to live 6 years less than a girl in Kensington, Chelsea and Westminster • but there are pockets of deprivation everywhere and health inequalities affect all parts of the country • Premature CHD deaths one of the biggest reasons for inequalities

Actions to tackle inequalities

• Providing a sure foundation through a healthy pregnancy and early childhood • improving opportunity for children and young people • improving NHS primary care services • tackling the major killers: CHD and cancer • strengthening disadvantaged communities • tackling the wider determinants of health

Drivers for Public Health (1)

Drivers for public health (2)

• Wanless and the PH imperative • Policy: Tackling Inequalities & Choosing Health • Public Service Agreements (PSA) • Community Service Agreements (CSA) • Local Authority Agreements (LAAs) • Local Strategic Partnerhsips (LSPs) • Local Operational Plans (LOPs) • Organisational change – reform agenda PBR / PBC and new structures • Financial imperatives and contrary aims

Summary

• Public Health contributes to health on a population basis by assessing needs, interventions and by implementing population level changes by working within and beyond the health sector • Public Health is vital if we are to prevent illness and have affordable health care, now and in the future • Organisational change and government policies both help and hinder the public health agenda

You should now know a little about:

• What is it?
