Background: Data on HBV prevalence among active
military personnel in Saudi Arabia(SA) are lacking. In addition, the
work-related risk of exposure is unclear. the objective of this study was to
estimate the seroprevalence of HBV and the risk ofHBV exposure among SA
National Guard (SANG) soldiers.
Methods: A cross-sectional study was performed
and included 400 male SANG soldiers working in Jeddah during January 2009.
All soldiers completed a questionnaire toassess their risk of exposure and
gave a blood sample to test for hepatitis serology markers.
Results: A total of 16 (4.0%) soldiers were
positive for HbsAg, 53 (13.2%) were positive for anti-HBc, and 230 (57.5%)
were positive for anti-HBs. None of the soldiers hadacute HBV infection, but
15 (3.8%) were chronic HBV carriers. A total of 152 (38.0%)soldiers were
susceptible to HBV infection, and 230 (57.5%) were immune to HBV infection,
primarily (84.3%) due to HBV vaccination. Compared with those who were
negative for anti-HBc (never exposed), soldiers who were positive for
anti-HBc were more likely to be older, have a lower education level, have a
higher income, have alonger service duration, have a household member with
HBV disease, have undergonesurgery, or have undergone endoscopy. In the
multivariate logistic regression model,older age, presence of a household
member with HBV disease and previous endoscopywere independent predictors of
HBV exposure.

Background: Although the risk of hepatitis B virus
(HBV) was reported to be higher in military personnel than the general
population in Saudi Arabia (SA), there is lack of studies assessing HBV
awareness among them. The objective was to evaluate the knowledge, attitude
and practice (KAP) of HBV infection among military personnel.
Methods: An intervention design with pre- and
post-education KAP questionnaire was completed among National Guard soldiers
working in Jeddah during January 2009. Educational intervention was provided
through educational leaflets, group and individual discussions, visual show,
and a lecture. A score was created from the correct answers to 58 questions.
Results: A total of 400 male soldiers with
mean age 30.7 ± 6.1 years completed both questionnaires. The majority had
school education (96.8%) and in the lower military ranks (66.0%). Only 19.5%
of soldiers reported HBV vaccine intake. The low median and inter-quartile
range of the pre-intervention score (16, 6–26) markedly increased after education
(to 53, 50–55, p<0.001). The overall improvement of mean KAP score (204%)
was also observed in all its component scores; disease nature (272%), methods
of transmission (206%), prevention and control (109%), attitude (155%), and
practice (192%). The improvement was evident irrespective of
socio-demographic characteristics and history of HBV vaccine. KAP scores were
significantly associated with higher educational levels, higher monthly income,
administrative jobs, and higher job ranks.
Conclusion: We are reporting a low level of
HBV awareness among Saudi military population. The study confirms the need
and effectiveness of focused multifaceted educational campaigns among the
military population.

BACKGROUND:
Several studies showed that the implementation of the Institute for
Healthcare Improvement (IHI) ventilator bundle alone or with other preventive
measures are associated with reducing Ventilator-Associated Pneumonia (VAP)rates.
However, the association with ventilator utilization was rarely examined and
the findings were conflicting. The objectives were to validate the bundle
association with VAP rate in a traditionally high VAP environment and to
examine its association with ventilator utilization.
MATERIALS
AND METHODS: The study was conducted at the adult medical-surgical intensive
care unit (ICU) at King Abdulaziz Medical City, Saudi Arabia, between 2010
and 2013. VAP data were collected by a prospective targeted surveillance as
per Centres for Disease Control and Prevention (CDC)/National Healthcare
Safety Network (NHSN) methodology while bundle data were collected by a
cross-sectional design as per IHI methodology.
RESULTS:
Ventilator bundle compliance significantly increased from 90% in 2010 to 97%
in 2013 (P for trend < 0.001). On the other hand, VAP rate decreased from
3.6 (per 1000 ventilator days) in 2010 to 1.0 in 2013 (P for trend = 0.054)
and ventilator utilization ratio decreased from 0.73 in 2010 to 0.59 in 2013
(P for trend < 0.001). There were negative significant correlations
between the trends of ventilator bundle compliance and VAP rate
(cross-correlation coefficients -0.63 to 0.07) and ventilator utilization
(cross-correlation coefficients -0.18 to -0.63).
CONCLUSION: More than 70% improvement of
VAP rates and approximately 20%improvement of ventilator utilization were
observed during IHI ventilator bundle implementation among adult critical
patients in a tertiary care centre in Saudi Arabia. Replicating the current
finding in multicentre randomized trials is required before establishing any
causal link.

Perception about vaccine compliance among
newly recruited in Saudi Arabia
|
ملخص المشاركة:
|
Background:
Compliance rates of vaccination among soldiers and health care workers are
historically low and had been conflicting. Although vaccines are available,
prevalence of infections is increasing per year in Saudi National Guard, the
vaccine compliance barriers could be contributing factors and require further
investigation.
Aim:
To explore perception and experiences about communicable disease, preventive
measures and barriers of vaccine compliance among Saudi military soldiers and
health care workers and to assess immunisation program among immunisation
services team.
Methods:
Focus groups discussion, each group was 8 participants and in depth
Interviews were conducted to achieve aim of the study. This research was
granted and ethically approved.
Data
analysis: Interviews were transcribed verbatim. Thematic content analysis
techniques was used in identifying, analysing, and reporting on themes in the
data, major domains and subdomains was identified and statements was coded
independently.
Implications: This study is expected to
provide assistance to health policy makers for good planning and resource
allocation for prevention and control of diseases and improving vaccine
compliance.

Sero-immunity profile, associated knowledge
and concerns of hepatitis B, varicella and measles infections among new
employees recruited in the Saudi National Guard
|
ملخص المشاركة:
|
Background:
The hepatitis B virus (HBV), varicella and measles are all
vaccine-preventable diseases that are easily transmitted in healthcare
facilities and military facilities. Despite efforts by various health sector
providers in Saudi Arabia, these diseases are still considered as the most
common reported infectious diseases among adults.
Aim:
To explore the epidemiological pattern, sero-immunity and associated
knowledge, and concern on HBV, varicella and measles infections among new
employees
Methods:
A cross-sectional study was performed among newly recruited health care
workers (HCWs) and military soldiers in the Saudi National Guard in 2014-15
through a quantitative analysis of sero-prevalence, sero-immunity and
epidemiological characteristics, knowledge among the newly recruited staff.
300
participants of HCWs and 300 of military soldiers were recruited and assessed
to complete a comprehensive questionnaire and 1000 of blood samples were
analysed for each group to find out targeted markers and 300-of blood samples
were matched with the questionnaires from each group. This research was
granted and ethically approved
Implications: This study is expected to contribute to
elaborating the epidemiological pattern of HBV, varicella and measles; among
high-risk groups. It should provide assistance to health policy makers for
good planning and resource allocation for prevention and control of these and
other diseases.
