Epidemiology and Biostatistics

by Raywat Deonandan, PhD

Epidemiology is the branch of medicine that focuses on the study of how diseases are transmitted in a specific population, with the ultimate goal of utilizing the obtained data to plan and execute successful public health interventions. Epidemiologists are skilled at designing and executing the type of study best suited to the research question at hand. To understand the data generated by studies, epidemiology uses the science of biostatistics, which is the branch of statistics that focuses on the collection, analysis, and interpretation of data derived from living organisms (human beings in this case).

This course requires the student to be familiar with the basics of arithmetic. Moreover, an open mind and patience are highly encouraged, as some concepts require a certain level of abstraction, whereas others may have to be rewatched to better grasp the topic.

Epidemiology and biostatistics are at the core of evidence-based medicine, allowing physicians, medical researchers, and healthcare professionals to draw almost definitive conclusions on the most effective and least damaging interventions available.

Both sciences could appear challenging to the medical student owing to the constant application of mathematical concepts. However, an introductory understanding of these fields is highly encouraged as they heavily impact various aspects of clinical practice, ranging from the design and implementation of clinical studies to the crafting of practice guidelines and assessment of the most likely diagnosis among differentials based on epidemiological data (e.g., men are more likely to suffer from heart disease and women are more likely to suffer from autoimmune illnesses).

It simply and in a nice way explained the Statistical Biases with examples.

By Ismael V. on 07. July 2021 for Pandemics

Bien explicados los conceptos. Esquemas claros y fáciles de entender. Debiera ser un curso aplicable a muchas instituciones de salud para que se entienda mejor la actual pandemia de COVID 19.
