Dr Thomas Cowling

Associate Professor

United Kingdom

I'm an Associate Professor in the Department of Health Services Research and Policy.

I re-joined this department in September 2023 after spending two years in the Department of Non-communicable Disease Epidemiology (Faculty of Epidemiology and Population Health). This role was based in the Electronic Health Records (EHR) Research Group and involved work on COVID-19 projects as part of the OpenSAFELY collaboration with the Bennett Institute at the University of Oxford.

During my first period in the Department of Health Services Research and Policy, I completed a Medical Research Council (MRC) Skills Development Fellowship (2018-2021). This fellowship focused on measures of patient morbidity and the prognosis of cancer patients, using national cancer and hospital data. I also worked on national audits for colorectal and prostate cancer with the Royal College of Surgeons of England.

I joined LSHTM in 2017 from Imperial College London where I completed degrees in Biomedical Sciences (BSc), Public Health (MPH), and Health Services Research (PhD). My PhD investigated access to general practice services nationally and was funded by a National Institute for Health Research (NIHR) Doctoral Research Fellowship.

Research

Improving healthcare services at scale

I work as part of a collaboration between LSHTM and the Royal College of Surgeons of England to evaluate and improve the quality of NHS cancer services in England and Wales. The National Cancer Audit Collaborating Centre (NATCAN) currently hosts 10 national cancer audits. I work across these audits on methodological aspects, particularly those related to data science and quality improvement. I also lead the two audits for urological cancers: the National Prostate Cancer Audit (NPCA) and National Kidney Cancer Audit (NKCA).

 

Innovation in methods and data science

I have a special interest in developing methods to analyse, visualise, and present large healthcare datasets. For example, I maintain a website on the timeliness of cancer diagnosis and treatment in England (here) using R and Quarto. I have published methods for developing high-dimensional models of comorbidities in hospital data, using either statistical or machine learning methods. Other topics include developing approaches to measuring cancer recurrence and causal inference in the context of competing risks.

 

Clinical epidemiology and real-world data

My research often investigates variation in the structure, processes, and outcomes of health services, particularly for cancer patients. This includes how the organisation of services affects the care that patients receive and the effects of treatments on patient outcomes. I also have a particular interest in prognosis research and prediction modelling. I specialise in the use of national, routinely collected datasets - often called 'electronic health records' or 'real-world data' - for health services research and clinical epidemiology.
