A new diagnosis of complex Post-traumatic Stress Disorder, PTSD – a window of opportunity for the treatment of patients in the NHS?

The concept of complex trauma has been around for a long time and in 2018, it’s expected to become a new diagnosis in the International Classification of Diseases eleventh revision, ICD-11, the World Health Organisation, WHO, manual used formally in the NHS. Psychiatric diagnosis often does not sit well with psychoanalysis, which is at least as interested in unconscious phantasy as it is in symptoms. But as psychodynamically-trained practitioners in the NHS we need to engage with ICD-11 and apply our own understanding to service design so that patients have access to treatment which works for them. The service where I work (a secondary mental health team in the London borough of Lewisham) has already been receiving referrals for ‘complex trauma’ for some time, despite its not being formally classified. Patients so described are most often those with a history of childhood sexual abuse, and refugees with a history of brutality and torture. Differential diagnosis includes personality disorder since many have difficulties with interpersonal issues. In this paper I want to discuss how we might understand the new diagnosis of complex Post-traumatic Stress Disorder, PTSD, and its implications for treatment in the NHS.
