This workshop is given on behalf of the Individual Patient Data Methods Group.

Workshop type: Training.

Objective: To provide information that will help reviewers make an active decision about whether the IPD approach is appropriate to their own circumstances. We also give guidance on all stages of the process.

Summary:
Systematic reviews and meta-analyses based on the collection, validation and analysis of data on individual participants (IPD) from the relevant trials have been described as the gold standard of review. While many aspects are similar to systematic reviews of aggregate data, there are additional features that require extra skills. Also, they are likely to take longer and may be more resource-intensive than other types of systematic reviews. They are, however, being used increasingly in a range of healthcare areas.

This workshop will consider the potential advantages a nd disadvantages of collecting IPD, including benefits arising from improved data quality, benefits afforded by the type of analyses that can be done, and advantages in achieving consensus from an international multi-disciplinary team on the results and interpretation. Based on our experience, we will provide guidance and practical tips on those aspects that differ with the IPD approach, such as: designing and planning; initiating and maintaining collaboration; and collecting, checking and analysing IPD and reporting results.

Review authors should be able to decide if the IPD approach is right for them and, if so, be able to start to plan an IPD review.

Intended audience: Review authors who are interested in, or are planning, a systematic review that includes IPD (basic knowledge of the systematic review process would be an advantage).

Technical level expected of participants: Intermediate.
