What is Evidence-Base Medicine: Explained by Dr. Max Mongelli

Dr. Max Mongelli is a respected name in the world of Obstetrics. His research on fetal growth, ultrasound, and early pregnancy problems has been detailed in several papers and doctoral thesis. He has also co-authored a book on fetal growth and has contributed to the development of software for creating customized antenatal growth charts which are now used all over the world. In this post, his take on the importance of evidence-based medicine is explained in detail.

Evidence-based medicine is a term which was first used for describing an approach which was used to teach medicine practice and improve the decisions taken by medical professionals for individual patients. Now, it has spread rapidly and is used for describing a decision-making approach which is used at every level in the healthcare industry.

What is EBM?

As per Dr. Max Mongelli, Evidence-Based Medicine (EBM) is a medical approach which is intended to improve the decision-making process by laying a major emphasis on evidence from past research. It can be defined as the use of currently available best evidence for taking decisions with respect to the care provided to individual patients.

Common Sources of EMB

Max Mongelli suggests that some of the most common sources of EMB include-
  • Textbooks
  • Observational studies
  • Traditional teaching
  • Decision analysis
  • Basic Sciences
  • Meta-analysis
  • RCT (Random Controlled Trials)
  • Computer simulation
Importance of RCT

Random Controlled Trials (RCT) according to Dr. Max Mongelli, play an important role in evidence-based medicine. These trials are very useful for evaluating new surgical and evaluating techniques. Moreover, they can also be applied to new diagnostic tests.

 
The main objective of these trials is to reduce the randomization bias, analyze techniques with the intention to treat patients and achieve statistical knowledge with the help of adequate size of the samples. Sealed envelope technique, computer software linked with a central monitoring station and block randomization are some of the most common randomization techniques used for these trials.

Evidence-base Medicine eliminates subjectivity in the medical decision making process. It aims at making it more objective by making it based on evidence rather than opinions.
