Aims
Treatment resistant depression (TRD) affects ≤20% of patients with major depressive disorder and is defined as failure to respond to ≥2 different antidepressants in the same major depressive episode (MDE). TRD patients’ outcomes are poor and real-world data from the UK are limited. The Treatment Resistant Depression in Europe Cohort was established to study patients being treated in local, routine clinical practice. The analysis presented here aimed to compare UK-specific data with data from other European countries included in the study.
MethodA prospective, multicentre, observational cohort study of TRD patients in Italy, Germany, Spain, Portugal, the Netherlands, the UK and Belgium was conducted. Patients aged 18–74 years with current TRD, Montgomery-Åsberg Depression Rating Scale (MADRS) score ≥20, and initiating a new treatment for depression, were eligible. Data from medical records, clinician assessments and patient-reported questionnaires were collected over time, with follow-up of ≥6 months.
ResultData from 411 patients were analysed. At baseline, UK patients (n = 49) had similar depression severity to the whole European cohort (34.7% vs 32.6% of patients categorised as severe based on MADRS score, respectively). Patients had experienced the current MDE for a mean (standard deviation [SD]) of 6.1 (7.9) years vs 2.6 (3.9) years and 14.3% vs 4.9% had experienced ≥5 treatment failures during this time in the UK and whole cohort, respectively. Total mean (SD) Sheehan Disability Scale (SDS) scores of 24.5 (5.1) and 22.4 (5.5) were reported for the UK and whole cohort, respectively. Unemployment and long-term sick leave rates were 38.8% and 20.4% in the UK and 30.2% and 19.0% in the whole cohort, respectively. At 6 months, 8.9% of UK patients were in remission, and 82.2% had not responded to treatment, representing the lowest remission and highest non-response rates across all countries.
ConclusionUK patients had been ill for longer and had more prior treatment failures than other countries in the study. They had high work and functional impairment, and the worst treatment outcomes of all the countries studied. UK TRD patients experience high disease burden; there is an unmet need for treatment strategies with better response rates.

Aims
To assess the incidence and treatments currently used in clinical practice for the treatment of treatment-resistant depression (TRD) in Scotland.
BackgroundPatients with major depressive disorder (MDD) who have not responded to at least two successive antidepressant (AD) treatments in a single episode are described as having Treatment-Resistant Depression (TRD). Epidemiological data on TRD in Scotland is lacking. Furthermore, there is no data to our knowledge on therapies prescribed in Scottish clinical practice to treat TRD.
MethodA retrospective, longitudinal cohort study was conducted using Clinical Practice Research Datalink (CPRD) medical records. Adult patients were indexed on AD prescription, requiring MDD diagnosis within 90 days, from Jan 2011-May 2018 with 360-day baseline and 180-day minimum follow-up periods. Failure of ≥2 adequate oral AD regimens following indexing constituted TRD classification. Incidence rates of MDD and TRD (within the MDD cohort) and treatment lines following TRD classification were derived.
ResultThe analysis included 20,059 patients with MDD (mean age 44 years, 63% female, median follow-up 59 months); 1,374 (6.8%) were classified as TRD. Median time-to-TRD classification was 25 months. The incidence rate of MDD was 15.9 per 1,000 patient-years and for TRD was 14.7 per 1,000 MDD-patient-years. For all first four post-TRD treatment lines, SSRI monotherapy was the most commonly prescribed therapy, followed by combination (dual/triple) therapy and augmentation therapy (at least one oral AD supplemented with lithium, an antipsychotic or an anticonvulsant therapy). At first-line of TRD treatment, 1,050 (76.4%) patients received monotherapy AD, 212 (15.4%) received combination AD therapy and 112 (8.2%) received augmentation therapy. The most common monotherapy treatments at first-line TRD were sertraline (15.6%), mirtazapine (13.8%), fluoxetine (12.2%) and venlafaxine (11.6%). Among combination therapies, mirtazapine, venlafaxine, sertraline and amitriptyline were frequently used. Among the TRD and MDD cohort, no somatic treatments were coded in CPRD, although the use of these treatments was likely underestimated.
ConclusionMonotherapy AD treatment was the most common therapy type for all four post-TRD treatment lines. These data support the need for new treatments that can achieve and maintain therapeutic response, and avoid continuous cycling through similar AD therapies.
