Lay Summary
1.1. BackgroundDepression is a very common major health problem. With 350 million people affected in the world, depressive disorder is the second leading cause of global burden.1 The high direct and indirect costs for major depression are largely due to significant problems in treatment.2 There are several effective treatments for depressive disorder, but the key challenge is how best to use and deliver currently available effective treatments.3International guidelines recommend antidepressant drugs as first line treatment for adults with moderate to severe depression.4 In England alone, 64.7m prescriptions of antidepressants were dispensed in 2016, more than twice the 31m antidepressants dispensed in 2006. Many patients, however, are given antidepressants, which, for them, prove ineffective or cause intolerable side-effects. This happens because antidepressants are prescribed without a clear understanding of which drug is the most appropriate medication for each patient in terms of both efficacy (effectiveness of treatment to reduce symptoms) and tolerability (the degree to which the side effects can be tolerated by a patient). The majority of prescriptions are for less than 30 days,5 while an adequate trial of antidepressants is generally recommended to be 6-8 weeks before changing or stopping the medication. A too short duration of treatment both limits the therapeutic effect6 and increases the risk of withdrawal symptoms because antidepressants should be tapered off over a period of 4 weeks.5 This can result in patients stopping the antidepressant early because they are prescribed a drug which might work for the “average person” but has not been tailored to them individually.1.2. Aim We aim to ultimately develop and test an evidence-based clinical decision support tool to personalise treatment in depression in the UK. We already have the knowledge which can markedly reduce these shortcomings in using the right antidepressant in treating depression. Implementing a careful analysis of existing data on antidepressants, we can better tailor the choice of a specific drug to a specific person, to increase the likelihood that the drug will be tolerable and effective. The overall aim of this project is to develop an internet-based system, which will help doctors, and patients together choose the best antidepressant for each individual with moderate to severe symptoms of depression, considering together both the efficacy and the adverse events of these drugs. This project specially aims to develop and test a novel precision medicine approach to the optimise the medical (drug) treatment of depressive disorder, which can be used in everyday clinical settings. We aim to develop a web-based platform using large and diverse datasets combining data from hundreds of thousands of patients, to inform shared decision-making at the individual patient level during the routine consultation between doctors and patients. The first phase of this project is obtaining individual patient data which will form a vital part of the dataset. 1.3. Objectives The main objectives of this project are to:1. Collect and summarise the best and most up-to-date scientific evidence about the effectiveness and side effects of antidepressants for major depression in adults and produce treatment recommendations;72. Produce a tool to combine these recommendations with information from electronic patient records and clinicians and patients' preferences, to tailor treatments to individual patients;3. Test whether use of the tool in real-world clinical settings helps patients to follow and keep to treatment, is acceptable to clinicians and patients and is economically feasible.
