About

Description

This codelist will be used to extract patients with Posttraumatic stress disorder (PTSD ) using OpenSAFELY. The codelist will be applied in studies looking at Trends and variations in the assessment, diagnosis, and treatment of PTSD.

Methodology

We include only SNOMED diagnosis codes for PTSD (including “acute”, “chronic”, “delayed onset”, and “other/unspecified” PTSD, and military-combat qualifiers where explicitly recorded). We exclude symptom terms, screening tools, scale items/scores etc to avoid false positives from suspected cases or symptom screening without a confirmed diagnosis. This choice may reduce sensitivity where PTSD is recorded only as symptoms.

Codelists are developed by a broad community of users for individual study purposes, which may or may not meet the needs of other studies. They should not be thought of as universal definitions of a particular condition.

We don't offer any guarantees about what they do or don't identify. Users should carefully check that any codelist meets their needs, and seek clinical input where appropriate.
