The department of Primary Care and Population Health (PCPH), UCL is offering three short courses on use and analysis of electronic health records 5 - 9 November 2012. • An introduction to primary care databases • Missing data and new methods for multiple imputation of longitudinal health records • An introduction to Hospital Episodes Statistics (HES). All three courses include a mixture of lectures and computer based practical sessions based on Stata 12. Course 1: An introduction to Primary care databases 5 November This course provides an introduction to analyses of primary care databases. The course material is developed around analyses of The Health Improvement Network, but participants can easily adapt the analyses and data management tools to other data sources. It is a practical course with a mixture of lectures and hands-on practical sessions. Course 2: Missing data and new methods for multiple imputation of longitudinal electronic health records 6-7 November This practical course will introduce participants to missing data issues in electronic health records such as primary care databases (THIN and GPRD), but the methods are also applicable to other datasets with longitudinal records. The course will provide a brief introduction to the statistical theory around missing data followed by hands-on practical sessions using the *ice* Stata command for multiple imputation and subsequent sessions using the newly developed algorithms to deal with multiple imputation of longitudinal records. Please notice some basic knowledge and practical experience with Stata will be an advantage for this course. Course 3: An introduction to Hospital Episode Statistics 8 - 9 November This practical course will introduce the participant to analyses using Hospital Episode Statistics (HES), which describes episodes of care in the hospital sector. The course will be of interest to those considering analyses of HES either stand alone or in conjunction with primary care database. The practical sessions will be run in Stata, but the conceptual learning will be applicable across statistical analysis clients. In hands-on sessions over 2 days, participants will develop analysis sets to address questions around length of stay, undertaking exercises designed to illustrate aspects of HES both in terms of potential and challenges. Participants will consider specific disease groupings, types of admission and its implications and linkage with ONS mortality statistics. We will end with a question and answer panel from recognised experts in the development of HES and its analysis. General information and costs: All three courses will be held in the Department of Primary Care and Population Health (PCPH), which is situated at the Royal Free Hospital, Hampstead in North London.
