Psychological aspects of peacekeeping operations

Healthy Warrior Effect With Deployment to United Nations Peacekeeping Operation: A Longitudinal Study Among Japan Ground Self-Defense Forces

INTRODUCTION

The "healthy warrior effect" (HWE), in which deployed military personnel are healthier than those not deployed, is known to be associated with deployment. However, the HWE associated with deployment to United Nations (UN) peacekeeping operations (PKO) has not been examined. This study examined the HWE associated with deployment to UN PKO by examining the impact of pre-deployment mental health on the likelihood of deployment and whether this difference persisted after deployment.

MATERIALS AND METHODS

This retrospective cohort study included 2,712 Japan Ground Self-Defense Forces personnel from four engineering units who consented to participate in annual mental health checks conducted between August and October 2015. The Kessler Psychological Distress Scale (K6) was used to assess general psychological distress before and after deployment. Logistic regression analysis adjusted for age, sex, and rank was conducted with deployment as the dependent variable and the pre-deployment K6 total score as the independent variable. Additionally, a mixed-effects model was performed with K6 total scores as the dependent variable, time and deployment as fixed effect factors, and the individual as the random effect factor.

RESULTS

Of the participants, 254 were in the deployed group, and 2,458 were in the non-deployed group. The pre-deployment K6 total score was significantly lower (t = 5.2, P < .001) for the deployed group (0.67 ± 1.60) than for the non-deployed group (1.26 ± 2.41). Logistic regression analysis showed an odds ratio for the K6 total score before deployment as 0.87 (95% CI = 0.79-0.94). The mixed-effects model exhibited a significant negative main effect of being deployed (t = -5.1, P < .001) and a significant interaction effect between time and being deployed (t = -2.5, P = .012).

CONCLUSIONS

Psychologically healthier personnel were more likely to be deployed for UN PKO and their better mental health status persisted after deployment, reflecting the HWE. However, personnel in good health may develop new mental health issues after their deployment, and more attention to health management will be essential before and after deployment.

Caring for Coronavirus Healthcare Workers: Lessons Learned From Long-Term Monitoring of Military Peacekeepers

BACKGROUND

The current outbreak of the coronavirus disease (COVID-19) is of unprecedented proportions in several regards. Recent reports suggest that many frontline healthcare workers (HCWs) suffer from mental health problems, including posttraumatic stress symptoms (PTSS). Previous studies have identified several key factors associated with short-term PTSS in pandemic HCWs, yet limited data is available on factors associated with long-term PTSS. Understanding the psychological impact of the pandemic on HCWs is important in planning for future outbreaks of emerging infectious diseases. In the current study, we look to findings from a highly relevant subsection of the trauma field, the military domain.

OBJECTIVE

Pandemic HCWs and military peacekeepers may experience similar stressors in the line of duty. This study investigated whether factors linked to short-term PTSS in pandemic HCWs were also associated with long-term PTSS in military peacekeepers.

MATERIALS AND METHODS

Peacekeepers who reported pandemic-relevant stressors during deployment to a UN peacekeeping mission were included in the study (N = 1,627). PTSS was self-reported using the Posttraumatic Stress Disorder Checklist - Military Version. Descriptive instruments were used to assess possible factors associated with PTSS. A multiple linear regression analysis was performed to explore associations between these factors and PTSS.

RESULTS

Our model accounted for 50% of the variance in PTSS, F(1503,11) = 139.00, p < 0.001. Age, relationship and employment status, preparedness, working environment, social support after deployment, barriers to disclose, recognition, and loneliness were all significantly associated with PTSS on average 30 years after deployment. The most important risk factors of long-term PTSS were personal barriers to disclose one's experiences and current unemployment.

CONCLUSION

Several factors linked to short-term PTSS in pandemic HCWs were associated with long-term PTSS in peacekeepers. We discuss how these findings may be used to prevent long-term PTSS in HCWs involved in the current COVID-19 outbreak.

Anesthesia during deployment of a military forward surgical unit in low income countries: A register study of 1547 anesthesia cases

BACKGROUND

Military anesthesia meets unique logistical, technical, tactical, and human constraints, but to date limited data have been published on anesthesia management during military operations.

OBJECTIVE

This study aimed to describe and analyze French anesthetic activity in a deployed military setting.

METHODS

Between October 2015 and February 2018, all patients managed by Sainte-Anne Military Hospital anesthesiologists deployed in mission were included. Anesthesia management was described and compared with the same surgical procedures in France performed by the same anesthesia team (hernia repair, lower and upper limb surgeries). Demographics, type of surgical procedure, and surgical activity were also described. The primary endpoint was to describe anesthesia management during the deployment of forward surgical teams (FST). The secondary endpoint was to compare anesthesia modalities during FST deployment with those usually used in a military teaching hospital.

RESULTS

During the study period, 1547 instances of anesthesia were performed by 11 anesthesiologists during 20 missions, totaling 1237 days of deployment in nine different theaters. The majority consisted of regional anesthesia, alone (43.5%) or associated with general anesthesia (21%). Compared with France, there was a statistically significant increase in the use of regional anesthesia in hernia repair, lower and upper limb surgeries during deployment. The majority of patients were civilians as part of medical support to populations.

CONCLUSION

In the context of an austere environment, the use of regional anesthesia techniques predominated when possible. These results show that the training of military anesthetists must be complete, including anesthesia, intensive care, pediatrics, and regional anesthesia.

The Wellbeing of Italian Peacekeeper Military: Psychological Resources, Quality of Life and Internalizing Symptoms

Working as a peacekeeper is associated with the exposure to acute and/or catastrophic events and chronic stressors. Hence, the meager literature about peacekeepers' wellbeing has mainly analyzed Post-Traumatic Stress Disorder (PTSD). This study aims to deep the analysis of the wellbeing of peacekeepers military. Based on the few studies on this population, we hypothesized that Italian peacekeeper military officers and enlisted men (n = 167; 103 males, 6 females, 58 missing) exhibit lower levels of internalizing symptoms (i.e., PTSD, depression, general anxiety, obsessions, and somatization) as compared to a control group (n = 60; 32 males, 28 females). Moreover, we hypothesized that peacekeepers have higher levels of psychological resources (i.e., self-efficacy, self-esteem, social support) and quality of life (i.e., higher life satisfaction and lower general stress). We compared the groups by means of MANOVAs on the subscales of the Psychological Treatment Inventory (PTI; Gori et al., 2015). We found that Italian peacekeepers have lower internalizing symptoms and higher levels of self-efficacy and self-esteem than the control group; however, no statistically significant differences were observed on perceived social support. Finally, peacekeepers have a higher quality of life: scores reflect higher life satisfaction and lower distress than the control group. This study is in line with previous literature supporting the claim that Italian peacekeeper military officers have sufficient psychological resources for coping with the stressful situations implied in peacekeeping missions. Future studies should deepen the analysis of the military's psychological characteristics by comparing war veterans and peacekeeper military.

External-cause mortality among 21 609 Norwegian male military peacekeepers deployed to Lebanon between 1978 and 1998

OBJECTIVE

To investigate external-cause mortality among 21 609 Norwegian male military peacekeepers deployed to Lebanon during 1978-1998.

METHODS

The cohort was followed from the 1st day of deployment through 2013, and mortality during deployment and post discharge was assessed using SMRs calculated from national rates in Norway. Poisson regression was used to see the effect of high-conflict versus low-conflict exposure.

RESULTS

For the total cohort, external-cause mortality was within expected values during deployment (SMR=0.80) and post discharge (SMR=1.05). In the low-conflict exposure group, a lower mortality from all external causes (SMR=0.77), transport accidents (SMR=0.55) and accidental poisoning (SMR=0.53) was seen. The high-conflict exposure group showed an elevated mortality from all external causes (SMR=1.20), transport accidents (SMR=1.51) and suicide (SMR=1.30), but these risks were elevated only during the first 5 years after discharge. This group also showed elevated mortality from all external causes (rate ratio, RR=1.49), and for transport accidents (RR=3.30) when compared with the low-conflict exposure group.

CONCLUSIONS

Overall external-cause mortality among our peacekeepers was equal to national rates during deployment and post discharge. High-conflict exposure was associated with elevated mortality from all external causes, transport accidents and suicide during the first 5 years after discharge from service.
