“…Another study amongst street recruited injecting drug users in San Francisco concurred with only a 47% vaccination completion rate [Lum et al, 2003]. Reasons cited for refusing HBV immunization include “just didn't want it” [Nyamathi et al, 2010] which was corroborated by the current study. Alternative strategies are needed and although controversial, authors of the San Francisco study suggested monetary remuneration [Lum et al, 2003].…”

Injecting drug users are the principal at risk group for blood borne viruses. The aim was to assess the feasibility of screening substance misusers for blood borne viruses, and to offer appropriate vaccinations/referral to hepatology services. This was a nurse led prospective 6-month study based at a large Substance Misuse Service in south east England. Of the 196 consecutive individuals assessed, 81 were eligible for HBV immunization of whom only 33.3% completed a vaccination course. Prevalence of positive serological markers were: anti-HBc 14.4%, HBsAg 1.5%, and HCV antibody 37.9%. Compared to men, women were more likely to accept blood borne virus testing (83.3% vs. 62.3%), have ever injected (89.6% vs. 76.3%), overdose (54.2% vs. 23.6%), be anti-HBc positive (27.5% vs. 8.8%), drink alcohol above national recommended guidelines (41.7% vs. 25.7%), and have a positive HCV serology (55% vs. 30.4%) (P ≤ 0.05 for all). Of the 73 individuals identified with a positive HBsAg and or HCV antibody, only 14 (19.1%) were known to hepatology services and 8 (20%) of those eligible subsequently accepted a specialist referral. In conclusion, serological markers for blood borne viruses remain high in substance misusers (anti-HBc 14.4%, HCV antibody 37.9%), with women more likely to be positive. Overall, only 33.3% and 20%, respectively, complete HBV vaccination and accept a hepatology referral. A multidisciplinary approach is paramount to address both the blood borne viruses and the substance misuse and realignment of hepatitis services to Substance Misuse Services may offer such a strategy.

“…The Comprehensive Health Seeking and Coping Paradigm (CHSCP) 15 served as the framework for the proposed study. This model has been successfully applied to investigations focusing on understanding HIV, Hepatitis B and C virus risk, and protective behaviors and other health outcomes among drug‐abusing, homeless, and impoverished adults 16‐20 and youth 21,22 . The CHSCP provides a foundation in exploring the importance of various cognitive and behavioral domains in relation to the selection of variables in this study; namely, sociodemographic variables, mental health, sexual activity, and risky drug and alcohol use.…”

This cross-sectional hepatitis health promotion study (N = 156) was designed to identify correlates of cocaine and methamphetamine use, among young, homeless persons living in Los Angeles County. Structured questionnaires were administered at baseline to assess sociodemographic characteristics, drug history and social support. Unadjusted analysis showed that older age, having a history of incarceration, injection drug use (IDU), 10 or more sexual partners and sex for money were associated with both cocaine and methamphetamine use. Logistic regression results showed that injection drug users had over 7 times greater odds of using each stimulant compared with non-users of injection drugs; those reporting at least 10 sexual partners and alcohol use in the past 6 months were more likely to use cocaine than their respective counterparts. African-Americans were also less likely than Whites to report cocaine use. Understanding of these relationships can guide interventions targeting the multiple challenges faced by this population.

“…In conclusion, MI was described as a promising tool for strategies for the promotion of health 42 and vaccination against Hepatitis A and B among patients undergoing methadone maintenance. 43 In the field of vaccination, only two studies used MI techniques to promote immunization among adults. 42,43 Although their results were promising, they were not significant, mostly because of the small sample size 43 and the specific targeted population (adults undergoing methadone maintenance treatment.…”

Background: Delayed vaccinations at 2, 4, and 6 months are associated with a higher probability of delayed age-appropriate vaccination during childhood. This study aimed to assess the effectiveness of an information session on immunization during infancy. Methods: An individual educational information session with motivational interview techniques for immunization of infants was conducted (experimental group) or not conducted (control group) during postpartum stay in a quasi-experimental cohort study. Immunization data were collected from the Eastern Townships Public Health registry at 3, 5, 7, 13, 19, and 24 months of age. Logistic regressions with repeated measures were performed to assess the intervention's impact. Relative risks (RR) were estimated. A multivariate model was obtained adjusted for confounding factors. Results: The experimental and control groups included 1140 and 1249 families, respectively. In per protocol analysis, a significant increase in VC of 3.2, 4.9, 7.3, 6.7, 10.6, and 5.1% was observed at 3, 5, 7, 13, 19, and 24 months. Children from experimental group had 9% more chance at a complete vaccination status between 3 and 24 months compared to children from control group (RR (95% CI): 1.09 (1.05-1.13), p < .001). Children with complete vaccination status at 3 months were more likely to have a complete vaccination status at 24 months (82.3 vs. 48.1%, RR (95% CI): 2.72 (2.28-3.24), p < .001). After adjustment, the estimated RR of the intervention's impact was 1.05 (1.02-1.07), p < .001. Conclusions: An educational information session about immunization based on motivational interview techniques conducted during postpartum hospitalization could improve immunization during infancy.
