Introduction: This study aimed to estimate the prevalence of HBV infection and its associated factors
as well as the knowledge of transmission modes among inmates in Champ-Dollon prison,
Méthode: A total of 116 individuals were interviewed using a standardized questionnaire on
sociodemographic characteristics and HBV knowledge. HBsAg, HBsAb and HBcAb were detected by
enzyme immunoassay.
Résultats: Prevalence for HBcAb indicating past or current infection was 44% (95%CI: 34.9-53.0) and
4.3% (95%CI: 1.4-9.8) had HBsAg indicating current infection. Region of origin is significantly
associated with HBV infection (p
Conclusion: The high prevalence combined with the ignorance of infection and the lack of knowledge
of transmission modes underlines the need for preventive actions in prison. A serological screening of
populations characterized by high HBV prevalence would enable the implementation of an intensive
educational program targeting contagious and susceptible inmates. Persons tested positive for HBV
could be excluded from vaccination thus leading to substantial reduction of costs. Prison settings
provide unique opportunities to vaccinate this high risk population. Vaccinating incarcerated persons
protects not only those individuals, but also the community at large.

Introduction: ICU caregivers are facing a demanding job (high level of technology and work load, stressful
environment). They are at high risk of developing anxiety, depression and a burnout syndrome (BOS), which can
impact on their welfare, performances and patients’ care. BOS favours absenteeism and job-leave, whereas the
shortage of ICU caregivers already started.
Méthode: Randomised, controlled, single blind study to evaluate the impact of the intervention of two
psychologists leading weekly sessions in small groups of caregivers (9 months). Individual meetings were
optional. Anxiety (HA)-depression (HD) assessed by HADS, BOS by MBI, before and after the intervention.
Résultats: 170 caregivers, 99(58%) responded the questionnaires before and after. Nurses: 77/99(78);
Men:24(24); Age-9):15(27)/14(25). CG: Scores mean (SEM):HA: before
6.5(.43)/after 6.7(.45); HD:4.2(.45)/3.8(.41); MBI:-15.8(2.33)/-18.5(2.07); Exhaustion:16.9(1.45)/15.1(1.35);
Depersonalisation:5.3(.77)/5.0(.58); Accomplishment:38.1(.87)/38.7(.78). ProportionsN(%) of severe
Anxiety:7(13)/11(19); Severe Depression:0/2(5); Severe BOS:15(41)/9(22). The ICU activities during the 3 time
periods of 3 months, Before, During, After were: Mortality(%): 8.8,8.3,13.0(p=0.009); ICU
admissions:272,242,173; Mean SAPS:39,37,37; Mean PRN:166,167,166, respectively.
Conclusion: Up to 32% of ICU nurses and nurse-assistants show high risk of BOS. Up to17/4% show signs of
anxiety/depression. After the intervention, the scores of BOS decreased significantly whereas it was unchanged in
the CG. The anxiety-depression scores tended to decrease more in the IG(no statistical significance). The
presence of psychologists might help to care for caregivers. Further investigation is needed for physicians.
