What we have

Archie Cochrane

CONFOUNDING FACTORS

The Evidence Level one Single study Quality of evidence – Consort – Grade

Systematic Review Meta-analysis

Why the unease ? Why is it some have no doubts Why is it some have massive doubts?

Medically unexplained symptoms

Propioibacterium freudenreichii in Emmental cheese

The reason we are uncomfortable Miracle cure for back pain: Agony ended by everyday antibiotics CHEAP antibiotics could end the agony of back pain for millions of Britons for ever. DAILY EXPRESS

Press reports before peer acceptance MMR studies Steroids in cord injury Hence our doubts

Magical thinking in improvement

Need for a science-based approach Rigorous theory and methods Fully specify interventions and mechanisms How much evidence is needed

Problem: childbed fever

Vienna Maternity Institution: rates of puerperal fever

Intervention was right; theory was wrong The logic of hand-washing with chlorine was right (the technical intervention worked) But the big theory of resorption of cadaveric particles was wrong And the adaptive work was disaster

Why we should wait for further evidence

How it all began.....

Conclusion MRI performed at 1-year follow-up in patients who had been diagnosed with sciatica and a herniated disc on MRI …… did not distinguish between those with a favorable outcome and those with an unfavorable outcome
