Do medical services personnel who deployed to the Iraq war have worse mental health than other deployed personnel?
ABSTRACT There is evidence of increased health care utilization by medical personnel (medics) compared to other trades in the UK Armed Forces. The aim of this study was to compare the burden of mental ill health in deployed medics with all other trades during the Iraq war.
Participants' main duty during deployment was identified from responses to a questionnaire and verified from Service databases. Psychological health outcomes included psychological distress, post-traumatic stress disorder, multiple physical symptoms, fatigue and heavy drinking.
A total of 479 out of 5824 participants had a medical role. Medics were more likely to report psychological distress (OR 1.30, 95% CI 1.00-1.70), multiple physical symptoms (OR 1.65, 95% CI 1.20-2.27) and, if men, fatigue (1.38, 95% CI 1.05-1.81) than other personnel. Female medics were less likely to report fatigue (0.57 95% CI 0.35-0.92). Neither post-traumatic stress disorder nor heavy drinking symptoms were associated with a medical role. Traumatic medical experiences, lower group cohesion and preparedness, and post-deployment experiences explained the positive associations with psychological ill health. Medics made greater use of medical facilities than other trades.
There is a small excess of psychological ill health in medics, which can be explained by poorer group cohesion, traumatic medical and post-deployment experiences. The association of mental ill health with a medical role was not the consequence of a larger proportion of reservists in this group.

ABSTRACT: Despite their growing numbers in the United States military, little has been published on healthcare providers (HCP) or female service members from conflicts in Afghanistan and Iraq. The purpose of this secondary analysis of data from the 2005 Department of Defense (DoD) Survey of Health Related Behaviors Among Active Duty Military Personnel was to determine gender differences in reaction to the impact of operational stress in deployed military healthcare providers. The unweighted study sample selected for this data analysis included results from female and male active duty military personnel over the age of 18 years (n=16,146) deployed at least once to Operation Enduring Freedom (OEF) or Operation Iraqi Freedom (OIF) within the past 3 years (n=1,425), for a final sample consisting of either officer (healthcare officer) or enlisted (healthcare specialist) personnel (n=455) (weighted n=23,440). Indices of psychologic distress and social relations were explored and compared. Enlisted female HCPs were more likely to be African American (42.3%) and single (63.0%) and represented the greater percentage with significant psychologic difficulties, as shown by serious psychologic distress endorsement (11.3%) and positive screen results for depression (32.2%). More harmful drinking patterns (Alcohol Use Disorders Identifications Test [AUDIT] score 8-15) were found in more female HCPs (enlisted 61.8%, officers 76.4%) compared with males (enlisted 41.1%, officers 67.1%). Female HCPs serving in the current military conflicts are reporting significant psychologic distress that may adversely impact their performance within the military, in theaters of operations, and in their lives at home. Implications for clinical care of female service members and veterans of current wars are addressed.Journal of Women s Health 01/2012; 21(5):496-504. · 1.42 Impact Factor

ABSTRACT: Among military personnel alcohol consumption and binge-drinking have increased but cigarette smoking has declined in the recent past. Although there is a strong association between smoking and PTSD the association between combat exposure and smoking is not clear. This cross sectional study was carried out among representative samples of SLN Special Forces and regular forces deployed in combat areas. Both Special Forces and regular forces were selected using simple random sampling. Only personnel who had served continuously in combat areas during the one year period prior to end of combat operations were included in the study. Females were not included in the sample. The study assessed several mental health outcomes as well as alcohol use, smoking and cannabis use. Sample was classified according to smoking habits as never smokers, past smokers (those who had smoked in the past but not within the past year) and current smokers (those smoking at least one cigarette within the past 12 months). Sample consisted of 259 Special Forces and 412 regular navy personnel. Prevalence of current smoking was 17.9% (95% CI 14.9-20.8). Of the sample 58.4% had never smoked and 23.7% were past smokers. Prevalence of current smoking was significantly higher among Special Forces personnel compared to regular forces. (OR 1.90 (95% CI 1.20-3.02). Personnel aged ≥35 years had the lowest prevalence of smoking (14.0%). Commissioned officers had a lower prevalence (12.1%) than non commissioned officers or other ranks. After adjustment for demographic variables and service type there was significant association between smoking and combat experiences of seeing dead or wounded [OR 1.79 (95%CI 1.08-2.9)], handling dead bodies [OR 2.47(95%CI 1.6-3.81)], coming under small arms fire [OR 2.01(95%CI 1.28-3.15)] and coming under mortar, missile and artillery fire [OR 2.02(95%CI 1.29-3.17)]. There was significant association between the number of risk events and current smoking [OR 1.22 (95%CI1.11-1.35)]. There was significant association between current smoking and combat experiences. Current smoking was strongly associated with current alcohol use. Prevalence of current smoking was less among military personnel than in the general population. Prevalence of smoking was significantly higher among Special Forces personnel.Substance Abuse Treatment Prevention and Policy 07/2012; 7:27. · 1.16 Impact Factor

ABSTRACT: Interest in the mental health of women deployed to modern military campaigns is increasing, although research examining gender differences is limited. Little is known about experiences women have had on these deployments, or whether men and women respond differently to combat exposure. The current study used data from a representative sample of UK Armed Forces personnel to examine gender differences among those deployed to Iraq and Afghanistan (n=432 women, n=4554 men) in three measures of experience: 'risk to self', 'trauma to others' and 'appraisal of deployment'. We examined the impact of such experiences on post-deployment symptoms of post-traumatic stress disorder (PTSD), symptoms of common mental disorder (CMD) and hazardous alcohol use. After adjustment, men reported more exposure to 'risk to self' and 'trauma to others' events and more negative appraisals of their deployment. Among both genders, all measures of combat experience were associated with symptoms of PTSD and CMD (except 'risk to self' events on symptoms of CMD among women) but not with alcohol misuse. Women reported higher scores on the PTSD Checklist--Civilian Version (PCL-C) among those exposed to lower levels of each experience type but this did not hold in the higher levels. Women reported greater symptoms of CMD and men reported greater hazardous alcohol use across both levels of each experience type. Examining men and women separately suggested similar responses to exposure to adverse combat experiences. The current findings suggest that, although gender differences in mental health exist, the impact of deployment on mental health is similar among men and women.Psychological Medicine 01/2012; 42(9):1985-96. · 5.59 Impact Factor

Aim: There is evidence of increased health care utilization by medical personnel (medics) compared to
other trades in the UK Armed Forces. The aim of this study was to compare the burden of mental ill
health in deployed medics with all other trades during the Iraq war. Methods: Participants’ main duty
during deployment was identified from responses to a questionnaire and verified from Service
databases. Psychological health outcomes included psychological distress, post-traumatic stress disorder,
multiple physical symptoms, fatigue and heavy drinking. Results: A total of 479 out of 5824 participants
had a medical role. Medics were more likely to report psychological distress (OR 1.30, 95% CI 1.00–1.70),
multiple physical symptoms (OR 1.65, 95% CI 1.20–2.27) and, if men, fatigue (1.38, 95% CI 1.05–1.81)
than other personnel. Female medics were less likely to report fatigue (0.57 95% CI 0.35–0.92). Neither
post-traumatic stress disorder nor heavy drinking symptoms were associated with a medical role.
Traumatic medical experiences, lower group cohesion and preparedness, and post-deployment experi-
ences explained the positive associations with psychological ill health. Medics made greater use of
medical facilities than other trades. Conclusions: There is a small excess of psychological ill health in
medics, which can be explained by poorer group cohesion, traumatic medical and post-deployment
experiences. The association of mental ill health with a medical role was not the consequence of a larger
proportion of reservists in this group.
Keywords: Iraq, medical personnel, mental health, military
stress because of their increased exposure to the death or
injury of others.1There have been some reports that military
medics have more mental ill health than their colleagues in
other trades. A small study of non-deployed UK military
healthcare professionals found an overall prevalence of psycho-
logical ill health of 35%.2The majority of reports on mental
health of military medical personnel are of small studies that
do not include a control group making it difficult to gauge
whether mental ill health is more common in medics than in
other military personnel.3–5
Medics are over represented amongst those referred to
mental health services and in those aero-medically evacuated
from Iraq. A total of 44% of all reservists, referred to field
mental health services in Iraq between February and June 2003,
were medics as were 7% of all psychiatric evacuees subse-
quently admitted to a military in-patient psychiatric facility
during the early phase of the Iraq war.6,7These findings are
consistent with studies which have reported that physical and
psychological ill health are high in UK civilian health care
workers but might simply reflect the relative ease of access to
medical services by military medics.8–10
Medics make up ?3% of the total strength of regular UK

(NAO) report identified medics as belonging to a ‘pinch point
trade’ in all three Services, with ‘insufficient trained personnel
to perform operational duties while enabling guideline levels
on amount of time away from home to be met’. The NAO
report estimated that 34% of A&E nurses and 21% general
surgeons were above guideline thresholds for duration of
deployments. Operational commitments are being met by the
use of large numbers of reservists.11In previous papers we
have shown both reservist status12and so called ‘overstretch’13
are associated with poorer health outcomes for deployed
The aim of this study was to compare the burden of
psychological ill health in deployed military medics with that
in all other trades who had served in the 2003 Iraq war. We
also assessed the possible reasons for associations between
medical trade and mental ill health in terms of medical and
combat traumatic experiences, unit cohesion and problems at

served on subsequent TELIC deployments. The study received
approval from King’s College Hospital local research ethics
committee and the Ministry of Defence (Navy) personnel
research ethics committee.
For this article, we include those in the TELIC 1 sample plus
those in the Era group who served on later TELIC operations
(TELIC 2–6). From responses to the questionnaire we identi-
fied 526 participants whose main duty during TELIC opera-
tions was medical or welfare. We were able to verify from
personnel and deployment databases held by the Defence
Analytical Services Agency (DASA) that 479 had a medical
role. We excluded 43 individuals from this analysis because we
were unable to confirm their role and four people were
reassigned to the ‘other main duty’ group because their roles
were not medical. Personnel endorsing a medical role could be
doctors, nurses, medical assistants, medical technicians, aero-
medical evacuation staff, medical administration staff and
other professions allied to medicine. The comparison group
were 5345 respondents who endorsed any other main duty
during TELIC operations. These duties were: combat, logistics/
supply, aircrew, engineering, catering/chef, intelligence, mili-
tary police, flight operations, administrative, musician, warfare
branch and Air Force protection.
The following measures of current health were included in
the questionnaire: the 12 item General Health Questionnaire
(GHQ-12) as a measure of psychological distress; the civilian
version of the post-traumatic stress disorder (PTSD) checklist
(PCL-C); the Chalder fatigue scale; 53 somatic symptoms as
used in our previous study of Gulf War veterans; the World
Health Organization Alcohol Use Disorders Identification Test
(WHO AUDIT).15–18Cases for each measure were defined as
those with a score of: 4 or more for GHQ-12; 4 or more for the
fatigue scale; 50 or more for the PCL-C; 18 or more physical
symptoms; 16 or more on the AUDIT scale, corresponding
to ‘high levels of alcohol problems’ (‘heavy drinking’).18In
addition, participants were asked to provide military and social
demographic details and information about their preparedness
for, and experiences during and after their deployment.
Odds Ratios (OR) with 95% confidence limits (95% CI) were
calculated to assess the association between role in theatre and
health outcomes using logistic regression to control for con-
founders and to adjust for potentially traumatic experiences,
morale and unit cohesion, and problems on return from
deployment. We checked, a priori, for effect modification by
enlistment status (regular or reserve), because of possible
qualitative differences between regular and reserve medical
professionals. Model adequacy was tested using a specification
test and goodness of fit with the Hosmer–Lemeshow test.
A quadratic term was included for the continuous variable
(age) when model inadequacy was indicated. Where model
adequacy was not improved by including quadratic or cubic
terms for age plausible interactions were investigated. Analyses
were performed using STATA 9.2. Appropriate survey
commands (svy) were used to account for the over sampling
of reservists in the original sample.
A total of 5867 responders who deployed on Operation TELIC
1–6 were included in the analysis. We found no interaction
between role and enlistment type (regular or reserve) for any
health outcome. Medics were older, of higher rank and
educational status than non-medical personnel. A higher
proportion of medics was female, in the army, belonged to
the reserve services, and had not experienced deployment
before the Iraq war (table 1).
The experiences of personnel during and after deployment
are shown in table 2. It was less common for medics to have
been deployed with their parent unit, to have felt well
informed about what was going on, for their seniors to have
been interested in what they thought or did, or to be able to go
to most people in their unit if they had a problem. Fewer
medics reported combat exposures but they more commonly
saw people wounded or killed, handled bodies and gave aid to
the wounded. Approximately two-thirds of personnel, irre-
spective of role, experienced diarrhoea and/or vomiting during
deployment but medics more often reported that they required
intravenous fluids, and said their symptoms prevented them
doing normal duties. Medics more often reported spending at
least one night under medical care. They were more commonly
evacuated by air from Iraq to the UK for medical reasons.
On return from deployment, more medics reported having
major problems, with fewer feeling well supported by the
military. More medics reported that other people did not
understand what they had been through.
Psychological distress and multiple physical symptoms, but
not PCL-C caseness or ‘heavy drinking’, were positively
associated with medical trade after adjustment for confounders
(model 1, table 3). Addition of a variable for ‘overstretch’
(up to 12 months/more than 12 months deployed in last three
years) to model 1 had no effect for any health outcome (results
not shown). The models for fatigue showed inadequacy, which
was not improved by adding quadratic or cubic terms for the
age variable. An interaction between trade and sex was thought

to be the most likely problem. We found a significant
interaction (P=0.002) between sex and trade for fatigue,
thus we report results for fatigue stratified by sex in table 3.
The separate models for males and females were adequate.
Medical trade was positively associated with fatigue symp-
toms for men but negatively associated for women (table 3).
All associations were of small effect size except fatigue in
women, which was moderate.

(model 4) were a plausible explanation for the associa-
tions observed after adjustment for confounders only, as
indicated by the reduction in odds ratio to the null after
adjustment. Likewise, cohesion and preparedness (model 2),
and post-deployment experiences (model 5) were also able to
explain the associations. Of note, the association of fatigue
with medical trade in women was not modified by any
In the course of exploring possible interpretations of the
results we observed a significant interaction (P=0.003)
between aiding the wounded and trade for psychological
distress. Among medics, psychological distress was less likely
in those who aided the wounded (adjusted OR 0.62 95% CI
0.35–1.08), although this difference was of only borderline
statistical significance, whereas for other trades psychological
distress was more likely in those who aided the wounded
(adjusted OR 1.47 95% CI 1.20–1.81). Medics who did not aid
the wounded had an increased OR of reporting psychological
distress compared to other trades who did not aid the
wounded (table 4). Medics who did not aid the wounded
did not differ in social or military demographic characteristics
from other medics. Personnel from other trades who gave aid
to the wounded were younger, more often in the army and to
be in combat units but adjusting for combat role did not
account for the association between psychological distress and
aiding the wounded (results not shown).
Medics were more likely to report psychological distress,
multiple physical symptoms and, if men, fatigue than other
deployed Service personnel. PTSD was not associated with
medical trade and nor was ‘heavy drinking’. The association of
mental ill health with a medical role was not the consequence
of a larger proportion of reservists in this group. This finding
was contrary to the expectation since we recently reported that
deployed reservists had a higher prevalence of all health
outcomes measured than regular personnel.12Medical trau-
matic experiences, but not combat traumatic experiences,
explained the associations with psychological ill health.
Likewise, cohesion and preparedness and post-deployment
experiences can explain the associations. We were able to
demonstrate that medics made a greater use of medical
facilities than other trades.
Our study provides an evidence of a small increase in some
psychological symptoms in medics compared to other military
trades, which only partially explains the greater level of
utilization of medical resources evidenced in our study and
also in health data routinely collected by the military.
Our results suggest that medics tended to use medical facilities
over and above the differences in symptoms reported,
especially in relation to spending nights under medical care,
medical evacuation from theatre, and use of intravenous fluids
because of diarrhoea and vomiting. A large gastroenteritis
outbreak occurred in UK deployed forces between 28 March
2003 and 3 May 2003 which disproportionately affected
medics.19However, despite their increased need for intrave-
nous fluids, there was no difference in reported episodes of
gastroenteritis between medics and others in our study.
Female health workers, in most occupational groups, in the
National Health Service (NHS) have higher levels of fatigue
than their male counterparts.20This is contrary to the findings
in this study, possibly explained by differences in the duties
undertaken by male and female military medics not found in
the NHS. Significantly more male medics ‘spent time in a
forward area in close contact with the enemy’ where duties
would include frequent movement of heavy equipment as
units advanced, whereas female medics were more often
deployed to the static field hospital.
What accounts for differences in
Traumatic experiences during deployment
Previous reports have suggested that medical personnel
experience higher rates of PTSD. Emergency room personnel,
intensive care unit nurses and ambulance service personnel
have been reported as being at increased risk of PTSD as
a result of their job experiences, with a substantial proportion
of ambulance workers meeting GHQ case criteria for psy-
chiatric symptoms.21–23Carson and colleagues reported that in
Vietnam nurse veterans witnessing death and serious injury to
others contributed to PTSD.1However, a study of US health
care providers deployed in Iraq and Afghanistan found that
frequent exposure to injured or dead personnel did not
increase the risk of either PTSD or depression.5We did not
find a difference between medical and other trades for PTSD,
but we did find strong evidence that medical traumatic
experiences such as seeing personnel wounded or killed, giving
aid to wounded and handling bodies explained the excess in
multiple physical symptoms and fatigue in males. Aiding the
wounded was associated with psychological distress in both
medics and other trades. For medics, whose training and
experience prepare them for handling casualties, not fulfilling
that role may be associated with increased psychological
distress, whereas for personnel in other trades exposure to
casualty handling increases psychological distress, an effect not
accounted for by combat role.

Cohesion and leadership
Our study also indicated that factors such as cohesion,
leadership and preparedness could be possible contributors to
an excess of psychological symptoms. Medics expressed more
negative sentiments regarding cohesion and leadership. Medics,
particularly regulars, were less likely to report that they
deployed with their parent unit. We found evidence that lack
of unit cohesion and negative views about leadership are able to
explain the excess reporting of psychological distress, multiple
physical symptoms and fatigue in males. We are not aware of
other studies that have covered these factors in military medical
personnel, but unit cohesion has been found to be the most
important motivating factor for combat soldiers, to influence
strain experienced by soldiers on operation, to be the most
powerful predictor of psychiatric symptoms, and to attenuate
the impact of life experiences on PTSD.24–27Studies in civilian
health workers have shown that workload pressures are
associated with psychological ill health in doctors and nurses
and that psychological distress is caused by low involvement in
decision making and poor social support at work.8,28
Another factor that explained the differences in this study was
post-deployment experience. Medics reported more major
problems on return, and more claimed that people did not
understand what they have been through and did not feel well
supported by the military. The duties undertaken by doctors
and nurses, regulars and reserves, are similar whether deployed
or at home, although the conditions in which they work are
very different. Many will return from deployment to work in
NHS hospitals, or MoD hospital units within NHS hospitals,
where the military support network is less accessible.
Strengths and limitations
This is the largest study of the psychological health of military
medical personnel based on a representative sample of the
deployed British military population. It directly compares
psychological ill health between medics and other trades, unlike
other studies which rely for comparisons on other reports using
different methods.5Although the largest study of this nature,
the statistical power to analyse PTSD symptoms was low, but it
was sufficiently high for our other outcomes of psychological
health. Our analysis included all medical personnel but it is
possible that associations may differ between the various health
professions as shown for civilian health workers.29–31
Although the peacetime roles of military doctors and nurses
are comparable to those in the civilian health service and their
roles on deployment, particularly if deployed to the field
hospital are not dissimilar, the role of deployed military
medical assistants may differ markedly from their peacetime
role. Some military medical assistants are effectively well
trained paramedics with additional schooling in basic nursing
care, prescribing and medical administration, whereas others
have only rudimentary medical training and little experience
other than administrative medical centre work. On deploy-
ment they may work as part of a medical team, headed by a
doctor, but at times they will be called upon to practice
independently with only limited and sporadic access to
medical supervision. The effect of this on psychological ill
health could not be considered in our study, but the great
majority of medics felt that their work in theatre matched their
trade experience and ability.
This study is cross sectional and therefore it is not possible
to determine the direction of causation for the associations we
report. Although there is potential for recall bias, we believe it
unlikely that there would be a difference in recall, between
medics and other trades, of the exposures used in the analysis.
Implication and conclusions
Our study has shown that there are small associations between
medical trade and psychological ill health and that there is
greater utilization of health resources by medics that could be
explained by easier access or to a greater level of dissatisfaction.
Our study provides important pointers as to how to address the
excess of psychological ill health. We have demonstrated that,
in comparison to other trades, among medics there was a
feeling of poor group cohesion, a perception that they were
poorly informed and, to some extent that their superiors were
not interested in them. Combat units typically spend up to a
year preparing and training together for an operational
deployment whereas a medical group is assembled only weeks
before deployment and, in recent years, has only two weeks pre-
operational training as a unit, factors which are likely to impair
effective communication and make leadership more of a
challenge. Good team relationships, thorough preparation
and high morale have been shown to protect against serious
adverse reactions to potentially traumatic experiences.32
The situation on the ground in Iraq has undergone change
since data collection for this study ended and many medics
have been re-deployed to Iraq, some on a number of occasions.
A follow-up study is necessary to assess whether psychological
health is deteriorating in deployed medics.

previously been shown to be associated with poorer
health outcomes for deployed personnel.
? The small excess of mental ill health found in deployed
medical personnel compared to other trades may be
explained by: poorer group cohesion and leadership;
exposure to wounded casualties; and post deployment
? The excess is not attributable to the larger proportion
of reservists in medical roles.
? Measures to increase group cohesion and effective
leadership may improve the mental health of deployed
? A need for improved access to military support
networks is indicated for medical personnel who
return from deployment to work in NHS hospitals.
