Suicide Data in Trauma Centers: Implications of Imprecision

BACKGROUND

Trauma registries exist to provide data for evaluating the quality of care of trauma patients. These data facilitate research and can be used for outreach, planning, and improvement in trauma patient outcomes. However, the accuracy of registry data related to suicide has not been well studied.

OBJECTIVE

This study sought to evaluate the accuracy of current trauma registry coding practices related to labeling injury as a suicide attempt among patients presenting to a Level I trauma center after self-inflicted injury.

METHODS

We conducted a single-center, retrospective cohort analysis of a Level I trauma center trauma registry on all patients with self-inflicted injuries from 2011 to 2021. Manual chart review was used to identify cases wherein patients' injuries were categorized as suicidal despite the absence of suicidal intent.

RESULTS

During this 11-year period, 537 patients were identified as having presented to the trauma center for traumatic self-inflicted injuries. Manual chart review revealed that 16% of these patients were incorrectly categorized as having attempted suicide despite their self-inflicted injury lacking suicidal intent (e.g., accidents, nonsuicidal self-harm).

CONCLUSION

We found that 16% of trauma registry patients were overcategorized as having attempted suicide. Trauma registry data are an important source of information for activities related to injury prevention in trauma centers. Imprecise coding of self-inflicted injury may lead to poorly targeted programs and interventions due to incorrectly represented injury causes and patterns in trauma patient populations, including suicide prevention.

The Effect of Gender on Identification and Interpretation of Non-Suicidal Self-Injury

INTRODUCTION

Reported rates of non-suicidal self-injury (NSSI) differ by gender but may be under-reported and under-recognised in men. People engaging in NSSI rarely seek professional help without encouragement, so others play a key role in its identification and potential intervention. The current research investigated others' interpretations of NSSI, examining whether gender affects the likelihood of NSSI identification and views of how common and acceptable NSSI is.

METHOD

Participants (N = 429; 74.1% female, 23.3% male; please see below for further demographic information) responded to two vignettes describing a person self-injuring by punching a wall or by cutting themselves. The person's gender in each vignette was manipulated. Following each vignette, the participants rated the level to which they agreed the behaviour was common for the gender of the person described, as well as the level to which they agreed the behaviour was acceptable for the gender of the person described, on a 5-point Likert scale. Following both vignettes, participants were presented with a definition of NSSI and rated the level to which they agreed cutting and wall-punching were forms of NSSI on 5-point Likert scales. Independent-samples t tests and goodness of fit χ2 tests were conducted as appropriate.

RESULTS

Participants were more likely to identify wall-punching as common for men and cutting as common for women. However, there was no significant difference in whether wall-punching was identified as NSSI or considered to be an acceptable behaviour, regardless of the gender of the person engaging in it. That is, although research suggests that men are far more likely to engage in wall-punching as a form of NSSI than women, participants did not recognise this. Overall, the results indicated a gender-dependent difference in how acceptable and common NSSI is thought to be, but no noticeable difference in identification of a behaviour as NSSI. Wall-punching, typically a form of NSSI engaged in by males, tended not to be identified as such.

CONCLUSION

There is an effect of gender on how NSSI is interpreted, and it seems that men's NSSI is, and will continue to be, under-recognised. This has important implications for the treatment of men's NSSI, which is more likely to be seen as aggression and therefore deserving of punishment than an attempt at emotion regulation.

Experiential Avoidance, Posttraumatic Stress Disorder, and Self-Injurious Thoughts and Behaviors: A Moderation Analysis in a National Veteran Sample

Experiential avoidance (EA) is associated with posttraumatic stress disorder (PTSD) and self-injurious thoughts and behaviors (SITBs) across different populations, and extant literature has demonstrated a strong relationship between PTSD and SITBs. However, no study has explored the potential moderating role EA plays in the association of PTSD with nonsuicidal self-injury (NSSI), suicidal ideation, and suicide attempts. The objective of the present study was to determine if EA would moderate the association with PTSD and SITBs such that the association between PTSD and individuals SITBs would be stronger among individuals with higher EA. In a large national sample of Gulf War Era veterans (N = 1,138), EA was associated with PTSD, lifetime and past-year NSSI, current suicidal ideation, and lifetime suicide attempts in bivariate analyses. Multivariate analyses detected a significant EA by PTSD interaction on lifetime NSSI (AOR = 0.96), past-year NSSI (AOR = 1.03), and suicide attempts (AOR =1.03). Probing of the interactions revealed that the respective associations between PTSD, lifetime and past-year NSSI, and suicide attempts were stronger at lower levels of EA (i.e., better), counter to our hypotheses. These preliminary findings contextualize the relationship between these variables in a Gulf War veterans sample and signal the need to further investigate these relationships. Further, these findings highlight the need for advancement in assessment and intervention of EA and SITBs.

Traditional Masculine Gender Role Norms and Nonsuicidal Self-Injury in Veterans

Reducing Veteran rates of suicide has long remained a top priority for the Veterans Health Administration, and as such, identifying correlates of suicidal behaviors is important to develop targeted interventions. Nonsuicidal self-injury (NSSI) has been identified as a robust predictor of suicide attempts; however, less is known about correlates of NSSI that may aid in upstream prevention efforts. Prior research suggests adherence to various traditional masculine gender role norms may be positively associated with NSSI. Thus, as the U.S. military is widely recognized for promoting and rewarding such norms, this study sought to build off previous research by examining the association between adherence to various masculine gender role norms and engagement in NSSI behaviors among a mixed-sex sample of U.S. Veterans (N = 124). Results showed the norm of emotional control was most strongly associated with lifetime engagement in NSSI behaviors (including the behavior of wall-object punching), whereas the norm of violence was associated with NSSI disorder. Interestingly, exploratory analyses indicated that these associations were primarily driven by women Veterans and sexual orientation status. Overall, the results highlight the importance of assessing for adherence to masculine gender role norms among all Veterans and speak to additional avenues for future research.
