Leveraging Electronic Health Records and Genetic Data for Personalized Antidepressant Treatment: A Causal Analysis Approach

The rising burden of mental health issues has led to a substantial increase in antidepressant prescriptions, with usage in England tripling between 1998 and 2018, accounting for 6% of all drugs dispensed. However, only one-third of patients respond to their first prescribed antidepressant, resulting in prolonged use and multiple medication trials. This highlights a critical gap in understanding antidepressant efficacy and treatment failure.


This PhD project aims to address this knowledge gap by analyzing electronic health records (EHRs) to assess treatment outcomes and integrate environmental, lifestyle, and genetic data to identify factors influencing individual responses. It will first utilize diagnosis codes and prescribing records from the Clinical Practice Research Datalink (CPRD) to create a comprehensive dataset of antidepressant use, examining treatment trajectories across depression episodes. Advanced algorithmic tools, including natural language processing (NLP), will be developed to analyze EHR data, generating metrics for treatment response and resistance. Descriptive and network analyses, as well as statistical models, will identify patterns in medication switching, trends, and differences in treatment responses based on demographic factors. Finally, the project will integrate EHR data with genetic information from the UK Biobank to explore biological mechanisms behind antidepressant outcomes. Causal analysis techniques like Propensity Score Matching and Causal Mediation Analysis will be employed to understand the direct effects of variables on treatment response.


This research will contribute to the development of personalized antidepressant prescribing, ultimately improving patient outcomes by uncovering patterns in treatment effectiveness.

Important Information for International Students

It is the responsibility of the student to apply for their Student Visa.


Please note that the EPSRC DRIVE-Health studentship does not cover the visa application fees or the Immigration Health Surcharge (IHS) required for access to the National Health Service. The IHS is mandatory for anyone entering the UK on a Student Visa and is currently £776 per year for each year of study.

 

Additionally, depending on your chosen project, some nationals may need to apply for an Academic Technology Approval Scheme (ATAS) certificate prior to applying for a visa. The ATAS application process can take up to 3 months and so it is essential that you apply for this early. Please note the following:

 

• If you need to apply for a student visa, you cannot submit your visa application until your ATAS certificate has been issued.

• If you are applying for any other visa, you cannot enrol at King’s and start your programme unless your ATAS certificate has been issued.

• If you apply late, you may not be able to join on the expected entry point and your registration may be postponed
