# Unit information: Clinical Trials and Statistics in 2018/19

Please note: you are viewing unit and programme information for a past academic year. Please see the current academic year for up to date information.

Unit name Clinical Trials and Statistics SOCSM0017 10 M/7 Teaching Block 2 (weeks 13 - 24) Professor. Chris Rogers Not open NONE NONE Bristol Medical School Faculty of Health Sciences

## Description

This unit will provide an overview of the different types of research design, with particular emphasis on clinical trials. It aims to provide students with a good understanding of the underlying principles of clinical trial design and knowledge of the appropriate use of statistics. Examples will be taken from cardiovascular disease and perfusion studies where possible, nonetheless the principles and techniques to be discussed apply equally to other areas of science and medicine. Students will gain an understanding and appreciation of how to conduct clinical trials successfully (e.g. appropriate data collection and case report form design for clinical studies, study size and power calculations, randomisation methods) and how to avoid common pitfalls (e.g. bias and confounding and how to minimize them). Essential concepts underlying statistical methods will be introduced (e.g. data distributions, hypothesis testing, confidence intervals, t-tests, non-parametric methods, chi-squared tests, odds ratios, relative risks etc). Students will gain sufficient knowledge to be able to identify which statistical analysis method should be employed. Mathematical formulae however, will be kept to a minimum. Importantly, the UK research governance framework and the EU directive governing the conduct of clinical trials will be covered.

## Intended learning outcomes

• Describe the key elements of a well-designed research study.
• Describe the common pitfalls when designing and conducting research and explain how they can be avoided.
• Define research hypotheses clearly and choose a suitable research design to address these.
• Decide on an appropriate statistical analysis method to apply and use.
• Carry out simple statistical analyses and interpret the output produced.

## Teaching details

• Web-based (in powerpoint-with recorded audio) and campus-based lectures, tutorials and practical demonstrations
• Online discussion forum(s)
• Self-directed study
• Face-to-face workshops

## Assessment Details

Coursework (contributing a total of 60% to the unit) consisting of:

• 2 sets of multiple choice questions (MCQs) of a simple format (e.g. select an answer from a short number of options, true/false), each contributing 10% to the unit, giving a total of 20%.
• 2 short answer question sets or extended MCQs, each contributing 20% to the unit, giving a total of 40%.

Please note that students will be given formative feedback on all coursework assessments.

Written exam (contributing a total of 40% to the unit and taken in Bristol) consisting of:

• 1 short answer paper contributing 20% to the unit.
• 1 set of MCQs contributing 20% to the unit.

The overall pass-mark for the unit will be 50%. However, students will be required to reach a minimum standard in both their coursework and their written exam; only 5% compensation between the total coursework element and the total exam element will be allowed.
