This course is available on the MSc in Global Health Policy, MSc in Health Policy, Planning and Financing, MSc in International Health Policy and MSc in International Health Policy (Health Economics). This course is available as an outside option to students on other programmes where regulations permit.

This course is relevant to all students with an interest in the health and social care interventions. 

Evidence review and synthesis methods (such as systematic reviews and meta-analyses) are increasingly used to evaluate the relative benefits and harms of healthcare interventions. In situations where direct, head-to-head comparisons of interventions do not exist, researchers also increasingly perform indirect comparisons (e.g., network meta-analyses) of two or more interventions to address comparative effectiveness questions. A broad range of decision making bodies across the health care sector (including health technology assessment bodies, drug and medical device licensing agencies, biopharmaceutical industry, and hospitals) need individuals equipped with the methods of reviewing and synthesising the existing body of evidence by performing systematic reviews and meta-analyses.

This course will be focused on the principles of reviewing and synthesising the existing body of literature. The course will have three components. The first will provide the rationale for adopting a systematic approach for evidence review and synthesis. It will equip students with the methods to undertake risk of bias assessments of randomised and non-randomised studies. The second component will focus on the quantitative synthesis of multiple studies in meta-analysis. The third component will discuss the opportunities and challenges of using evidence for decision-making. 

The intended learning outcomes of this course will be the following:

• Describe the rationale for adopting a systematic approach to literature review
• Define the principal threats to validity both in individual studies and collections of studies
• Critically evaluate the quality of randomised and non-randomised studies in oral and written form
• Assess heterogeneity in a collection of studies
• Design and perform a systematic review and meta-analysis evaluating a health care intervention in a group setting
• Describe the opportunities and challenges of using systematic review and meta-analysis findings for decision making

This course will be delivered through a combination of lectures and seminars totalling a minimum 25 hours during Michaelmas Term. Students will have access to lecture materials delivered as short online videos. Students will also work in small groups to complete weekly self-directed learning activities and meet with seminar leads for weekly feedback on their progress. An online computer workshop will be held to introduce students to systematic review and meta analysis software.

There will be a departmental reading week in week 6 of term.
