About

Ronan is particularly interested in the use of electronic patient records for research and has over 10 years’ experience in the use of large primary care databases (CPRD/GPRD, QResearch and THIN).

His longer term aims are:
- to develop and make publicly available appropriate methods that will increase the accessibility and utility of large primary care databases for research; and
- to identify the limits of primary care databases as a data source for clinical studies, in particular for clinical prediction models.

Qualifications

  • MSc Health Psychology, City University, London, 2000
  • MA Psychology, University College Dublin 1991
  • BA Psychology, University College Dublin, 1990

Biography

Prior to being involved in research, Ronan spent about 10 years working in the NHS and for social services as an assistant psychologist and a residential social worker in mental health, learning disabilities, and elderly services.

Since then, he has worked on the General Practice Research Database at the Office for National Statistics, on the QResearch general practice database at the University of Nottingham, and has used The Health Improvement Network (THIN) general practice database for a variety of studies while at the University of Birmingham.

Research

  • Development of clinical prediction models using primary care data.
  • Design and analysis of case-control and cohort studies using primary care data.
  • Analysis of a stepped-wedge randomised control trial to prevent CVD in primary care.
  • Development of a method to impute missing data on ethnicity in cancer registries.
