Importance of 
Evidence-Based 
Medicine on Research 
and Practice
Introduction
Evidence-based medicine is the 
system of practicing medicine 
in such a way that it results in 
improving outcomes and 
reduces the overall healthcare 
cost. Evidence-based medicine 
also takes care of the individual 
preference of the patients, 
along with the clinical expertise 
of the clinicians.
Evidence-Based 
Medicine
Evidence-based medicine is the 
multidisciplinary approach to 
provide the best care to the 
patient at the right time. 
Evidence-based medicine 
involves the use of the 
experience of the clinician and 
the updated evidence available 
to make the best decision 
related to the treatment 
regimen.
It is to be noted that the 
research article required to alter or 
continue the treatment strategy should 
be strong and fulfill the criteria to 
become credible evidence. This creates 
a basic difference between evidence-
based medicine and traditional 
medicine.
In evidence-based medicine, the doctor 
and the healthcare professionals should 
make the best possible application of 
the evidence to raise the standard of 
patient care. The process of evidence-
based medicine comprises evidence 
selection and knowledge translation in 
terms of patient care.
Evolution of the 
Evidence-Based 
Medicine
 Gordon Guyatt coined the term 
‘Evidence-Based Medicine’ in the year 
1990. This term was first used in an 
article published in the year 1992 in 
JAMA. However, the use of evidence-
based medicine started much before 
this.
 Before evidence-based medicine, 
medical decisions were made based on 
individual clinician’s experience or the 
marketing strategies of 
pharmaceutical companies. Many 
clinicians disagreed with this approach 
and advocate for the practice, which is 
backed up by the latest medical 
knowledge.
Importance in Research 
and Practice
 Updated information to the 
clinicians: Evidence-based medicine 
requires the clinicians to read the 
information and latest research articles 
related to their therapeutic area. 
 Data for making treatment 
decisions: Because of the 
advancements in technology, and the 
availability of user-friendly databases, 
the clinicians now have access to the 
research data and knowledge. 
 Enhance the quality of overall 
care: Through the best-quality peer-
reviewed articles, the clinicians have the 
data and procedures for caring for the 
patients. 
 Make the healthcare system more 
accountable and 
transparent: Patients and their 
relatives, many times, have concerns 
about the treatment strategy of the 
doctor. 
 Improves outcomes: It is one of the 
best effects of evidence-based 
medicine. A lot of data is available that 
indicates that if evidence-based 
medicine is applied logically, it will 
help in improving the overall 
healthcare outcomes.
Practicing the Evidence-
Based Medicine
 Step I: In the first step, the clinicians 
should determine the problem that 
requires to be solved. The primary aim of 
problem identification should be such 
that solving the problem will result in 
improves outcomes and prevent or 
reduce the frequency of recurrent of the 
condition.
 Step II: In the next step, the clinicians 
should search for evidence that may best 
solve their problems. For searching the 
evidence, the clinician should look for 
credible evidence. The sources of 
evidence may be categorized through an 
evidence-based medicine pyramid.
 Step III: The clinicians then critically 
analyze every evidence to determine 
whether it aligns with the solution that 
needs to be determined. 
 Step IV: Once the best solution, 
through the evidence, is determined, 
the doctor may apply the solution in his 
clinical practice.
 Step V: The clinicians should evaluate 
the performance of the new treatment 
strategy. They should measure if there is 
an overall improvement in health 
outcomes.
Conclusion
Evidence-based medicine plays 
an important role in research 
and practice. Through 
evidence-based medicine, 
clinicians can implement the 
best treatment regimens for 
their patients.
