Overview
Brief Summary
It is well known that patients suffering from chronic pain report higher levels of pain, anxiety, and depression if they have experienced a traumatic event. However, little is know about pain area and widespreadness.
In this retrospective study, we want to investigate whether pain area and widespreadness differs in chronic pain patients with and without traumatic events. To test this hypothesis we will retrospectively analyse pain drawings collected at the pain outpatient department from Hannover Medical School. Participants will be divided into four groups depending on the severity of their traumatic events: no trauma; accidental trauma; interpersonal trauma; post-traumatic stress disorder (PTSD).

Outcomes
Primary Outcomes

Time Frame: First visit of each patient at the Pain outpatient department of Hannover Medical School between 2019-02-28 and 2020-07-07
Widespread pain index (WPI) derived from electronic pain drawings (SymptomMapper). The score ranges from 0 (no pain) to 19 (pain affects all possible regions).
Difference in pain area
Time Frame: First visit of each patient at the Pain outpatient department of Hannover Medical School between 2019-02-28 and 2020-07-07
Pain area derived from electronic pain drawings (SymptomMapper). The score ranges from 0 to 100% body area.
