Real World Evidence from Retrospective Study: A New Approach

Choosing the best accessible therapeutic and preventive measures to avoid suffering from diseases leading to disability and death is an important goal for all health care professionals. To accomplish this objective, the health care community seeks information on data to support critical decision making while choosing interventions during clinical practice.  A retrospective clinical study looks backward in time, usually using the medical records and interviews with patients who are already known to have a medical condition. The study looks backward and examines exposures to suspected risk or protection factors in relation to an outcome which is established at the beginning of the study. A “Retrospective study” is played out a posteriori, utilizing data on occasions that have occurred previously. In most cases, some or most of the information has just been assembled and put away in the library. In a retrospective study, different patient populations can be compared to one or several outcomes.


Currently, Real-world data and real-world evidence are helping in health care major decision making. Retrospective studies help in collecting the information from different sources of health records which can be used for evaluating new approaches to prevention and treatment. They can be used to help formulate the hypothesis, focus the questions and identify any major issues before a prospective study begins. These studies are relatively inexpensive and faster to conduct than other studies. A retrospective study is often used in medicine, but they are now used by real-world study and real-world experience also. Abiogenesis Clinpharm is an emerging Clinical research organization in Hyderabad (CRO) in Hyderabad which provides client-specific services in the area of clinical development of drugs. Retrospective Studies conducted at Abiogenesis Clinpharm are economical, quicker to analyze and finish than prospective randomized controlled clinical trials.
