What is the argument for evidence-based healthcare?

Health service delivery should be based on best available evidence which emerges from findings of rigorously conducted research


Which two factors should the evidence for healthcare consist of?

Effectiveness (of drugs, practices, interventions)

- Cost-effectiveness (in a system with finite resources where should money be spent to gain the maximum utility?)


Identify 4 factors which influence healthcare practices

- Professional opinion

- Clinical fashion

- Historical practice and precedent

- Organisational and social culture


What is evidence based practice?

Evidence-based practice involves the integration of individual clinical expertise with the best available external clinical evidence from systematic research


Systematic reviews and meta-analyses have become very important in informing evidence base.

Why are they needed?

- Traditional literature reviews may be biased and subjective

- Quality of studies reviewed variable and sometimes poor

- Help address clinical uncertainty

- Highlight gaps in research/poor quality research


Provide 4 reasons as to why systematic reviews are useful to clinicians

- Offer quality control and increased certainty

- Offer authoritative, generalisable and up-to-date conclusions

- Reduce delay between research discoveries and implementation

- Help to prevent biased decisions being made


What are the 3 practical criticisms of the evidence-based practice movement?

- An impossible task to create and maintain systematic reviews across all specialities

- Challenging and expensive to disseminate and implement findings

​- Requires ‘good faith’ on the part of pharmaceutical companies



What are the 3 philosophical criticisms of evidence-based practice?

- ‘Does not align with most doctors’ modes of reasoning 

- Aggregate, population-level outcomes don’t mean that an intervention will work for an individual

- Professional responsibility/autonomy
