Dear all,
This is a request for information on how to do that essential but often
under-reported step in EBM: integrating the best available evidence with the
patient's values and preferences.
Situation: My colleagues and I are trying to figure out the best way to
introduce evidence into our conversations with patients and to integrate their
values with the best available evidence.
Background: We are familiar with one suggested way of integrating the evidence
with the patients values:
Users’ Guides to the Medical Literature XX. Integrating Research Evidence With
the Care of the Individual Patient

The concept of factoring in the likelihood of being helped and harmed is
attractive – and while the arithmetic formula outlined in the above article
looks relative simple:
LHHA=[(1/NNT)*ft*s]: [(1/NNH)*fh]
Where
LHH = likelihood of being helped vs harmed
NNT= number needed to treat to help/benefit
NNH= number needed to treat to harm
ft = risk of the treatment outcome event relative to that of the average control
fh = risk of the harm outcome event relative to that of the average control
s=severity factor,
we wonder how many health professionals do easy it is to carry out this piece of
arithmetic in the real-life of every day clinical practice..
Assessment: We wonder if and how fellow healthcare professionals use this
approach in practice? Has anyone developed a systematic approach to do this
for the majority of patients they provide care for?
Recommendations: I am interested in finding out the following information:
1. It would be interesting to hear of other practitioners experience in using
such approach in their own practice.
2. If you have knowledge of other publications using a similar or easier
approach I would be grateful for your knowledge and sources of information.
3. If anyone is has tips / tools / experience of using this approach in regular
day-to-day clinical practice I would like to hear about them too.
Many thanks for your help
