Mr Allan Hackshaw

This course is available on the MSc in Global Health. This course is available with permission as an outside option to students on other programmes where regulations permit.

An optional course for students taking MSc Global Health and available to other students taking relevant MSc programmes, particularly Health, Population and Society and Health and Population Development

The course provides students with an understanding of key epidemiological concepts associated with describing disease/mortality or other health-related features of a population (such as causes of disease or early death), and evaluating ways to treat disease, or prevent disease or early death. This will include: (a) tools for descriptive epidemiology (incidence, prevalence and survival); (b) measures of association, using relative and absolute measures; and (c) confounding and bias. The course introduces the concepts associated with the design and analysis of research studies that are used to examine features of population health and burden of disease. It also introduces students to the principles of causality and risk factors. Students will cover the most common types of research studies used to evaluate human health (observational studies and clinical trials). The course includes fundamentals of data interpretation, including effect sizes, and data analysis (e.g. regression modelling).

Teaching is structured in the form of lectures and seminars. Lectures introduce students to key epidemiological concepts and methods, and complemented by seminars. Most lectures and seminars are based around specific published papers in epidemiology, used to illustrate the concepts. These articles would be sent to students in advance of each class, and students are expected to prepare a short review of the article, using an accompanying set of questions on the study design and interpretation.

Summative assessment is based on an examination to assess student’s understanding of epidemiological concepts and their ability to interpret study results. Summative assessment also includes a research proposal in which students are expected to apply the basic principles of epidemiology in the context of a well-defined research question.

14 hours of lectures and 10 hours of seminars in the LT. 3 hours of help sessions in the ST.

Four 2-hour lectures, six 1-hour lectures, and 5 2-hour seminars in the LT.  One 3-hour revision seminar in the ST.   

Students will be expected to produce 1 project in the LT.

Students will be expected to produce one project in the LT, based on designing a research study, using a topic chosen by the student. In week 6, students would submit a draft report (up to 2000 words) of their project so far (not assessed, but feedback provided), as formative coursework. After this, the report would be expanded and finalised (~3000 words). In the report, students are expected to: (i) identify an epidemiological research question of relevance to global health, with justification, (ii) provide a summary of the key literature, and identify gaps in knowledge, and (iii) describe an epidemiological study to address their research question, including the methods.
