Work-related posttraumatic stress disorder (PTSD) and other emotional diseases as consequence of traumatic events in public transportation: a systematic review

First responders are generally considered to be at greater risk for full or partial posttraumatic stress disorder (PTSD) than most other occupations because their duties routinely entail confrontation with traumatic stressors. These critical incidents typically involve exposure to life threat, either directly or as a witness. There is a substantial literature that has examined the risk factors, symptom presentation, course, and comorbidities of PTSD in this population. However, to our knowledge, there are no systematic reviews of treatment studies for first responders. We conducted a systematic review of the PTSD treatment literature (English and non-English) in order to evaluate such treatment proposals based on what is known about treating PTSD in first responders. We especially sought to identify randomized controlled trials (RCTs) whose primary outcome was PTSD. Our search identified 845 peer-reviewed articles of which 0.002% (n=2) were bona fide RCTs of PTSD treatment in first responders. Both studies tested a psychosocial treatment. We did not locate a single psychopharmacologic RCT for PTSD in first responders. An additional 2 psychosocial studies and 13 case or observational studies comprised the remaining extant literature. Though both RCTs showed significant large treatment effects (d=1.37; h=0.92), the literature is startlingly sparse and is not sufficient for evidence-based recommendations for first responders.

Purpose To examine the influence of employment social support type (e.g. co-worker, supervisor, general support) on risk of occurrence of low back pain, and prognosis (e.g. recovery, return to work status) for those who have low back pain. Methods Systematic search of seven databases (MEDLINE, Embase, PsychINFO, CINAHL, IBSS, AMED and BNI) for prospective or case–control studies reporting findings on employment social support in populations with nonspecific back pain. Data extraction and quality assessment were carried out on included studies. A systematic critical synthesis was carried out on extracted data. Results Thirty-two articles were included that describe 46 findings on the effect of employment social support on risk of and prognosis of back pain. Findings show that there is no effect of co-worker, supervisor or general work support on risk of new onset back pain. Weak effects of employment support were found for recovery and return to work outcomes; greater levels of co-worker support and general work support were found to be associated with less time to recovery or return to work. Conclusions The evidence suggests that the association between employment support and prognosis may be subject to influence from wider concepts related to the employment context. This review discusses these wider issues and offers directions for future research.

Background ‘Suicide hotspots’ include tall structures (for example, bridges and cliffs), railway tracks, and isolated locations (for example, rural car parks) which offer direct means for suicide or seclusion that prevents intervention. Methods We searched Medline for studies that could inform the following question: ‘What interventions are available to reduce suicides at hotspots, and are they effective?’ Results There are four main approaches: (a) restricting access to means (through installation of physical barriers); (b) encouraging help-seeking (by placement of signs and telephones); (c) increasing the likelihood of intervention by a third party (through surveillance and staff training); and (d) encouraging responsible media reporting of suicide (through guidelines for journalists). There is relatively strong evidence that reducing access to means can avert suicides at hotspots without substitution effects. The evidence is weaker for the other approaches, although they show promise. Conclusions More well-designed intervention studies are needed to strengthen this evidence base.
