Primary Care Database User Group Meetings
Thursday 7th April, 3.30-5pm
Partner bereavement and risk of herpes zoster: results from two population-based case-control studies in Denmark and the United Kingdom
Sigrun Alba Johannesdottir Schmidt (Aarhus University, Denmark, and visiting scholar at LSHTM, UK)
I will be presenting the results from an ongoing large case-control study on the association between partner bereavement and herpes zoster. In our study, we combine nationwide Danish registry data and electronic health records in CPRD and HES. I will present the project with a focus on comparing the methodological advantages and disadvantages experienced when using these Danish and British data sources.
Serum creatinine elevation following renin-angiotensin system blockade, adherence to monitoring guidelines, and long-term cardiorenal risks
Morten Schmidt (Aarhus University, Denmark, and visiting scholar at LSHTM, UK)
I will be presenting CPRD data examining to what extent patients who initiate treatment with ACE-inhibitors or Angiotensin II receptor antagonists (ARBs) in primary care in the UK have the guideline recommended pre- and post-initiation monitoring of serum creatinine. Also, we examine the association between serum creatinine changes following ACEi/ARB initiation and long-term cardiorenal risks.

Jordana Peake, from the UCL Institute for Women's Health presented on the use of patient identifiable information for data
linkage for research into neural tube defects in ethnic communities. And Jenny Woodman, from the UCL Institute of Child Health, told us about the role
of the GP for children with (possible) abuse and neglect: a mixed methods study.
14th June 2012
This usergroup meeting focussed on time series analyses. Lisa Szatkowski and Tessa Langley from the UK
Centre for Tobacco Control Studies and University of Nottingham presented

data. Pia Hardelid (ICH, UCL), Nick Freemantle (PCPH, UCL) and Ruth Gilbert (ICH, UCL).
