I am a Statistician working within Primary Care at the University of Exeter Medical School. I have a strong interest in routine data, both derived from primary care and other healthcare settings. This interest spans two approaches which are 1) using routine data to explore a variety of health research questions and 2) understanding the limitations of, and the interpretation of, routine data used to inform health service delivery.

Prior to joining the medical school in early 2016 I worked for the Cambridge Centre for Health Services Research at the University of Cambridge. Before this I completed an MSc in Medical Statistics at the London School of Hygiene and Tropical Medicine. Prior to retraining as a statistician, I worked for 10 years as a physicist at the British Antarctic Survey and UCL where I also completed a PhD in space physics.

Research

Research interests

As a statistician I work across a broad range of health and healthcare areas, but there are three areas which have been a focus of my research to date. The first of these is patient experience. Patient experience is about the non-clinical aspects of how patients interact with the health service. I’ve worked extensively with the General Practice Patient Survey data as well as that from the Cancer Patient Experience Survey. These two national annual surveys provide a wealth of data which allow you to drill down to a level of detail which is simply not possible in smaller studies. Further my work as part of the NIHR funded IMPROVE project has help understand how reported outputs from the GP Patient Survey may or may not represent a wider picture.

The second area of focus for me is early diagnosis of cancer. By looking at cancer registry data and other routinely collected data we can gain insights into who is at most risk from delayed diagnosis of cancer and potential reasons why. Armed with this knowledge it should be possible to more effectively target interventions at those in most need and at the right point in the cancer journey. Thirdly, I have been and continue to be, involved in the evaluation of a number health service intervention such as integrated care pilots. A focus here has been on the use of secondary care data as a marker of the success of primary care interventions.

Across all three themes is a methodological interest in organizational variation. In particular I am interested in how we quantify it and how misleading crude statistics can be. Health systems are awash with indicators of activity and quality and care is needed if they are to be used appropriately.
