Back to the talk:Once it was so easy
An individual patient went to a doctorThe doctor:
made a diagnosis (probably wrong),applied a treatment (probably ineffective)
The patient:died, orgot better

Health care before the 20th century
HospitalsPlaces of sanctuaryPatients “patiently waiting for death”

PhysiciansMasters of “watchful waiting”Judicious application of herbal remedies

Type I diabetesThe first chronic disease?
Discovery of insulin changed a rapidly fatal disease of childhood into a lifelong disorderNow compatable with a normal life span, but large differences in actual attainmentHealthy survival requires co-ordination of efforts by many people and organisations

… so now …
A patient with arthritis, Parkinsons, heart failure, bronchitis, diabetes, and depression goes to a family doctorThe patient is referred to a series of medical specialists, nurses, other health professionals, all working together in a network, collaborating with each otherShe receives multiple powerful and effective medicines, all of which are affected by her organ function and by the other drugsShe remains under continuing review for the remainder of her now active and fully engaged life

First question:does health care improve health?
Thomas McKeown and the role of medicine
![Page 13: Re-orienting healthcare system to deliver health gain](https://reader031.fdocuments.net/reader031/viewer/2022020621/61e700cd35c12d1c3a7f12f3/html5/thumbnails/13.jpg)
Medical nemesisIvan Illich
Medicine is not just useless, it is actually harmfulThe concept of iatrogesesisSocial, cultural and structural ‘Hospitals have become
monuments narcissistic scientism’
![Page 14: Re-orienting healthcare system to deliver health gain](https://reader031.fdocuments.net/reader031/viewer/2022020621/61e700cd35c12d1c3a7f12f3/html5/thumbnails/14.jpg)
Archie CochraneEffectiveness and efficiency
“All effective care should be free”"It is surely a great criticism of our profession that we have not organised a critical summary, by specialty or subspecialty, adapted periodically, of all relevant randomized controlled trials."
![Page 15: Re-orienting healthcare system to deliver health gain](https://reader031.fdocuments.net/reader031/viewer/2022020621/61e700cd35c12d1c3a7f12f3/html5/thumbnails/15.jpg)
Florence NightingaleThe concept of avoidable mortality
![Page 16: Re-orienting healthcare system to deliver health gain](https://reader031.fdocuments.net/reader031/viewer/2022020621/61e700cd35c12d1c3a7f12f3/html5/thumbnails/16.jpg)
Avoidable mortality
Concept developed further by Rutsteinin 1970sCauses of death at ages where death should not occurInitial examples included
diabetes under age 49, leukaemia under age 15, Asthma under age 65
![Page 17: Re-orienting healthcare system to deliver health gain](https://reader031.fdocuments.net/reader031/viewer/2022020621/61e700cd35c12d1c3a7f12f3/html5/thumbnails/17.jpg)

What happened where medical care failed to modernise?
Death rate from avoidable mortality in UK and Russia similar in 1965, when little could be doneGap began to widen in 1970s, and has continued to do so since

So health care does make a difference
Next question:How can we maximise health gain?
![Page 22: Re-orienting healthcare system to deliver health gain](https://reader031.fdocuments.net/reader031/viewer/2022020621/61e700cd35c12d1c3a7f12f3/html5/thumbnails/22.jpg)
Living in interesting times
“People first”Concern about future costsFocus on life threatening diseases
![Page 23: Re-orienting healthcare system to deliver health gain](https://reader031.fdocuments.net/reader031/viewer/2022020621/61e700cd35c12d1c3a7f12f3/html5/thumbnails/23.jpg)
Five maxims
1. Prevention is better than cure2. Timely investment pays off3. You can’t leave it to chance (or the
market)4. Anticipate change5. Trust but verify
![Page 24: Re-orienting healthcare system to deliver health gain](https://reader031.fdocuments.net/reader031/viewer/2022020621/61e700cd35c12d1c3a7f12f3/html5/thumbnails/24.jpg)
1. Prevention is better than cure?
Does investment in health promotion save subsequent costs of health care?Does investment in health increase future national wealth?
(to pay for health and social care, among other things)
![Page 25: Re-orienting healthcare system to deliver health gain](https://reader031.fdocuments.net/reader031/viewer/2022020621/61e700cd35c12d1c3a7f12f3/html5/thumbnails/25.jpg)

Ageing populations
Costs of care increase with proximity to death, not chronological age
It is expensive to die, not to grow oldClear evidence for compression of morbidity
Tomorrow’s 80 year olds will be much fitter than today’s
![Page 27: Re-orienting healthcare system to deliver health gain](https://reader031.fdocuments.net/reader031/viewer/2022020621/61e700cd35c12d1c3a7f12f3/html5/thumbnails/27.jpg)
Investment in health –investment in wealth creation
![Page 28: Re-orienting healthcare system to deliver health gain](https://reader031.fdocuments.net/reader031/viewer/2022020621/61e700cd35c12d1c3a7f12f3/html5/thumbnails/28.jpg)
2. Timely investment pays off?The health production function
Human capitalthe right mix of skilled workers
Physical capital Appropriate facilities Effective drugs and technology
Intellectual capitalResearch and developmentImplementation of evidence
Social capitalNetworks and connectionsTrust

Money is not enoughMoney is only useful if there is something to buy
Doctors can’t be trained overnightHospitals don’t come in flat packs
UK reforms increased funding very rapidly
Predictable resultCost inflation

Social capital: the case of magnet hospitals
39 hospitals defined prospectively as providing a good nursing environment;matched with 195 controls with similar characteristics in other areas;after adjustment for severity; magnet hospitals had a 4.6% lower mortality rateboard certification, technology etc.. not relevant
Aiken et al., 1994
![Page 35: Re-orienting healthcare system to deliver health gain](https://reader031.fdocuments.net/reader031/viewer/2022020621/61e700cd35c12d1c3a7f12f3/html5/thumbnails/35.jpg)
The inter-relationship of practically everything
A family is injured in a high speed car crashThey arrive at an emergency department
There is no paediatric service – it has been moved into the communityThe eye injuries cannot be treated as the ophthalmologists have been relocated to an independent treatment centre to concentrate on waiting lists for cataractsThe complex hip fracture cannot be treated, because the orthopaedic surgeons have been relocated to an independent treatment centre to concentrate on waiting lists for keen replacementsThere is no microbiologist to speak to about the wound infection because the service has been moved 200 miles away
![Page 36: Re-orienting healthcare system to deliver health gain](https://reader031.fdocuments.net/reader031/viewer/2022020621/61e700cd35c12d1c3a7f12f3/html5/thumbnails/36.jpg)
3. You can’t leave it to chance?
Surely we could simply leave it to the marketThe invisible hand must be better at organising this complexityNo-one at the centre can possibly second guess all the individual decisions
![Page 37: Re-orienting healthcare system to deliver health gain](https://reader031.fdocuments.net/reader031/viewer/2022020621/61e700cd35c12d1c3a7f12f3/html5/thumbnails/37.jpg)
… except….
Markets in health care don’t work so well
Many people who need health care don’t realise itEven if they do, they may be deterred from seeking itThey often don’t know what they wantThose providing care may not realise these people even exist
![Page 38: Re-orienting healthcare system to deliver health gain](https://reader031.fdocuments.net/reader031/viewer/2022020621/61e700cd35c12d1c3a7f12f3/html5/thumbnails/38.jpg)
Reaching out to those in need
‘[Doctors] tend to gather where the climate is healthy... and where the patients can pay for their services’
Ivan Illich"the availability of good medical care tends to vary inversely with the need for it in the population served."
Julian Tudor Hart

Opportunistic behaviourCream-skimming
Enrolment for a HMO on 6th floor of a building without an elevatorDeclining to treat complex and expensive, but inadequately reimbursed patientsConcentration on conditions with high returns
Short-termismHigh volume elective surgery, but no provision of training

In summaryGood health doesn’t arise by chanceIt helps to have a plan and some idea of how you will achieve itDon’t wait for diseases to become life threatening
