ACUNA CONEJERO, Stephanie Sofía; AGUADO MARQUEZ, Nerea María; ALVAREZ CASADO, Jorge  y  AMORES TOLA, Rebeca. Post-traumatic stress disorder in emergency response. Med. segur. trab. [online]. 2021, vol.67, n.264, pp.232-244.  Epub 14-Mar-2022. ISSN 1989-7790.


Emergency workers are exposed to potentially traumatic situations, so it would be of interest to show whether there is a relationship between these professionals and the development of Post-Traumatic Stress Disorder (PTSD). The aim is to know if there is evidence of such relationship, in addition to identify associated vulnerability factors and effective preventive and therapeutic interventions.


Systematic review through bibliographic research in MEDLINE in PUBMED, SCOPUS, EMBASE, WOS, Cochrane Library Plus, IBECS, LILACS and CISDOC databases, using MeSH terms «emergency responders» and «stress disorder, post-traumatic». CONSORT, STROBE quality standards were applied and we checked the evidence using the SIGN system.


They were selected 6 RCTs (n = 783) and 1 historical cohort study (n = 4487). The most frequent risk factors are: female sex 2.93 (1.42-6.07), diagnosis of depression or anxiety 4.72 (2.33-9.57) in chronicity and substance abuse 5.12 (2.62-9.97) in worsening of PTSD. There are no improvements in preventive interventions (p = 0.712-0.749) and (p = 0.246-0.881). In 2 RCTs, a reduction in the severity of PTSD symptoms was evidenced by Cognitive Behavioral Therapy (CBT) (p = 0.001 and 0.05). There are 2 RCTs with oxytocin that reveal an impact on neural regions for emotional management (p = 0.0024-0.044).


There is a causal relationship between PTSD and emergency workers (evidence 2+). As a treatment, CBT is effective in reducing PTSD symptoms (evidence 1+). The aforementioned vulnerability factors were shown as the most important (evidence 1+). Oxytocin showed evidence as a therapeutic ally (evidence 1+).
