Profile

Sally studied Mathematics and Statistics at Reading University and Medical Statistics at the London School of Hygiene and Tropical Medicine. In 1991 she joined the department of General Practice at St. George’s Hospital Medical School, as one of the first statisticians to specialise in primary care. During this time she developed an interest in cluster randomised trials. Working with Professor Martin Bland, she wrote a series of statistics notes in the BMJ to provide researchers with accessible information and practical solutions to the issues of sample size and analysis.

She has collaborated on a number of randomised trials in primary care, both individually and cluster randomised. In 2000-2004 she collaborated on a cluster randomised trial of an educational intervention to reduce blood pressure by reducing dietary salt in Ghana.  In 2004 she published a systematic review of home blood pressure monitoring to improve blood pressure control and is currently completing a trial of home blood pressure monitors among stroke patients.

She has co-authored two books: ‘Presenting Statistics from Proposal to Publication’ with Janet Peacock, written to help researchers clearly present statistics in peer review publications, thesis and grant applications. ‘A Practical Guide to Cluster Randomised Trials in Health Services Research’ with Sandra Eldridge will be published in early 2012.

In 2010 she joined the Pragmatic Clinical Trials Unit as senior statistician.

Summary

Recent and ongoing research projects:

  • Home blood pressure monitoring among stroke patients
  • Anti epileptic drug monitoring in pregnancy trial (EMPiRE)
  • Development and validation of a prediction risk model for risk of complications in early onset pre-eclampsia (PREP)

Research

Research Interests:

Sally’s main research interests are in the design of cluster randomised trials and improving the understanding and reporting of statistics among researchers.
