The aims of Evidence Based Medicine are to improve patient care based on principles and treatments that have been proven to be correct,
preferably by prospective randomised control trials rather than simply relying on conventional wisdom, experience and clinical judgement.
Evidence Based Medicine therefore has the potential to impact on:
1. Modes of practice. Evidence Based Medicine may provide pathways for clinical decision making and subsequent patient treatment.
2. The establishment of treatment protocols, particularly in institutions.
3. The establishment of medico-legal risk, negligence and the determination of reasonable and appropriate care.
4. The provision of services within hospitals or communities maybe based on EBM. If a particular treatment or operation has been
   shown not to work it may not be made available. Treatments, which have been expressly shown to be efficacious, may be fast
   tracked into service or more quickly funded.
5. The availability of private and private sector funding.
However, it is time to review the appropriateness of Evidence Based Medicine. There are many actual and potential problems with
Evidence Based Medicine which include:
1. The knowledge base in medicine is extensive and exhaustive. There is a large body of knowledge which is both factually and
   intuitively correct.
2. The collection of Cochrane level 1 or 2 evidence using predominantly prospective randomised controlled trials is arduous, expensive
   and exacting. It has been estimated that fewer than 20% of patients who present to a specialist during an ordinary working day
   would have a clinical problem in which the results of a prospective randomised control trial would direct the clinical management.
3. Cochrane level reviews consistently show that much of the data relating to specific medical issues is usually level 3 or level 4 data.
   Often only one or two prospective randomised controlled trials will have been performed. However errors occur in these trials.
   Frequently second and third trials which confirm the outcomes are not present. Sometimes also the results of reputable prospective
   trials are conflicting.
4. Various institutions and funding bodies are now starting to insist that an Evidence Based Medicine procedure be followed prior to
   the introduction or the maintenance of specific forms of treatment. Many Cochrane Review Boards have a lack of front line clinicians.
   It is also possible that these review panels have excellent expertise in terms of data analysis and the ability to review information
   but may have a weakened clinical understanding as to the practice of medicine
5. The absence of evidence supporting a particular treatment may be used as an argument that that treatment is either unnecessary
   or wrong.. It is important that reviewers report a historical absence of information in that context and do not fill a void with their own
   equally unproven beliefs of prejudices.
6. The establishment of protocols and guidelines across broad treatment areas using EBM as its intellectual base may lack flexibility
   and clinical applicability. Protocols and guidelines are at their strongest when they extensively cover a very small area.
7. Trials, reviews and subsequent guidelines become rapidly outdated. They are difficult to replace due to the extensive cost and
   workshopping that is needed to modify them.
EBM has a useful place to place in medicine and surgery but its limitations need to be recognised.

It is now becoming a recognized standard of good practice that new surgical procedures like new drugs are carefully and formally
assessed before being available for widespread use. History is littered with examples of surgical procedures that are supported by the
wise and the good to be subsequently shown to be ineffective or downright harmful. To avoid such disasters it is essential to compare
the new procedure with appropriate measures directly against the existing gold standard technique.
Although correct evaluation is essential it is also extremely difficult. Patients need to trust their surgeon and believe that he is doing
the best possible operation for them. It does little for the surgeon patient relationship to be told that the doctor is testing out two
procedures because he does not know which is best. It is even less helpful to that relationship to be aware that it is a computer and not
the surgeon who will select the therapy to be given. All surgeons must inevitably be biased towards particular operations. That is why
they recommend them. Evidence based medicine and particularly randomized clinical trials are there to avoid or at least reduce to a
minimum the bias in a trial. Just as they are more difficult to undertake it is therefore more important that we all become used to EBM.
I should like to illustrate the problems and potential solutions to conducting an surgical RCT by illustrating with some of the problems
and solutions we encountered during the Evaluate hysterectomy Trial. As this is probably the largest RCT ever performed in
gynaecological surgery I can assure you that we came up against almost every problem that you might expect and some that you may
not. We will cover issues of trial design and the vital issue of sample size. Almost invariably we choose a sample size that is about the
size of population we expect to have available in the time we think we can spare for the study. Before we performed the Evaluate study
11 other RCT’s were performed comparing LH with TAH. Each of these studies made specific statements that there results confirmed
that both procedures were safe. The size of the studies varied from 40 to 200 patients and the total number of patients in all the studies
was 695. In order to detect a difference of the magnitude we could expect we calculated that we would need 450 patients per trial arm
using an 80% power and a two-sided type 1 error of 5%. ie if the purpose of the study was to determine if the new method of
hysterectomy was as safe as its predecessor, none of the studies were remotely powered to detect this. From that point of view they
were a complete waste of time and the conclusions of safety drawn were invalid. Sadly this is the case for most trials. Obviously other
data with greater magnitudes of differences can still be analysed from these trials but this example is intended to point out the need
to match the size of the trial to the order of magnitude of difference we expect from the procedures.
The message is clear. Carefully drawn up trials are essential but the techniques of trial design and execution are important and like all
statistics garbage in is garbage out.
