Background: Clinicians working in a women's prison in British Columbia observed hepatitis C sero-conversion among inmates, prompting this study to determine: the characteristics of women who do and do not report illicit drug use in prison; patterns of drug use inside prison; factors associated with illicit drug use that might contribute to bloodborne transmission inside prison. Methods: A cross-sectional observational data set was created using an anonymous 61-item self-administered survey. Results: Eighty-three percent (104/126) of eligible inmates participated. Seventy-four percent (77/104) reported their current prison sentence was related to illicit drug use and 25% (26/104) reported their ethnicity as Aboriginal. Ninety-three percent (97/104) reported a prior history of illicit drug use, of whom 70% (68/97) reported a history of injection drug use. Thirty-six percent (37/104) reported illicit drug use in prison, and 21% (22/104) reported injection drug use in prison. Fifty-two percent (54/104) reported hepatitis C sero-positivity, and 8% (8/104) reported HIV sero-positivity. Of the 22 women who reported prison injection drug use, 91% (20/22) reported hepatitis C infection and 86% (19/22) reported injecting with shared needles inside prison, with or without bleach cleaning. Women were more likely to report illicit drug use in prison if they had had illegal sources of income prior to incarceration (p=0.0081, OR 3.19), had previously injected drugs (p=0.036, OR 2.97), and had first injected drugs at a friend's house (p=0.066, OR 2.70). Interpretation: The majority of women reporting prison injection drug use also reported hepatitis C sero-positivity and shared needle use. Canadian prisons are risk situations for transmission of bloodborne pathogens, and provide opportunities for harm reduction strategies. [ABSTRACT FROM AUTHOR]

Objective: To report the findings of a knowledge survey of nurse and physician immunization providers., Design: Cross-sectional postal survey assessing demographic characteristics and vaccine knowledge., Setting: British Columbia (BC)., Participants: Nurse and physician immunization providers in BC., Main Outcome Measures: Knowledge of vaccine-preventable diseases, vaccines in general, and vaccine administration and handling practices., Results: Survey responses were received from 256 nurses and 292 physicians (response rates of 48.6% and 18.3%, respectively). Most nurses (98.4%) reported receiving immunization training outside of the academic setting compared with 55.6% of physicians. Overall, nurse immunizers scored significantly higher than physician immunizers on all 3 domains of immunization knowledge (83.7% vs 72.8%, respectively; P < .001). Physicians scored highest on the vaccine-preventable disease domain and least well on the general vaccine domain. Nurses with more experience as health care providers scored higher. Physicians scored higher if they were female, served patient populations predominantly younger than 5 years, or received immunization training outside of academic settings., Conclusion: In BC, nurse immunizers appear to have higher overall immunization knowledge than physicians and are more likely to receive immunization training when in practice. Physician immunizers might benefit most from further training on vaccines and vaccine administration and handling.

Background: Despite the fact that hepatitis C virus (HCV) is a relatively common infection in Canada, particularly in British Columbia (BC), there is a paucity of information on actual HCV prevalence in pregnant women. At present, pregnant women are only screened if they fit risk criteria, which may result in under-identification of HCV in this population. The purpose of this study was to determine the overall prevalence rate, age and geographic distribution of reported HCV infection among pregnant women in BC, and compare results to a previously conducted anonymous seroprevalence survey., Methods: Reported HCV prevalence was determined through a confidential database linkage of all prenatal screening results at the Canadian Blood Services (CBS) with all HCV test results at the Provincial Laboratory, from May 2000 to Oct 2002. Data were stratified by age group and geographic location, and subsequently compared to an anonymous prenatal seroprevalence survey conducted in 1994., Results: The overall HCV prevalence rate was 50.3/10,000 (95% CI 46.3-54.6), or 0.5% of the cohort. Prevalence was highest in the northern BC region (66.2/10,000, 95% CI 51.4-85.3) and lowest in the populous suburban region southwest of Vancouver (38.0/10,000, 95% CI 32.3-44.8). Of note, the rate of reported HCV among pregnant women was significantly lower than the anonymous seroprevalence rate: 50.3/10,000 vs. 91.3/10,000 (p < 0.0001)., Conclusion: Rates of reported HCV among pregnant women were approximately 50% lower than the rates determined by the anonymous seroprevalence survey. Further research is needed to determine the relative merits of the current selective screening policy versus universal prenatal HCV screening in pregnancy.

Aim: This paper is a report of a study conducted to examine the attitudes, beliefs, behavioural intentions and self-reported behaviour of nurses and physicians relating to key immunization behaviours and compare the findings for nurses and physicians., Background: Immunization is an important and effective public health intervention. Understanding immunization providers' attitudes and beliefs toward immunization has the potential to improve educational efforts and lead to behavioural change., Method: A postal survey was conducted with all immunization providers in British Columbia, Canada, in 2005. The survey elicited data on demographics, practice characteristics, attitudes, perceived social norms and perceived behavioural control related to key immunization behaviours., Results: Responses were received from 344 nurses and 349 physicians. The response rate was 67% for nurses and 22% for physicians. More nurses than physicians thought that administering all recommended vaccines at one visit was important (89.2% vs. 63.2%P < 0.001); nurses felt more pressure from parents to administer all recommended vaccines (82.4% vs. 48.7%P < 0.001), and nurses were also more likely to intend to give all recommended vaccines at one visit (98.8% vs. 73.8%P < 0.001). Both nurses and physicians thought that their own receipt of influenza vaccine each year was important (88.9%, 87.1% respectively P = 0.65)., Conclusion: The foundational work done to develop the survey tool can be used to modify it so that survey findings can be validated according to the Theory of Planned Behaviour. The results could inform the development of behavioural change interventions targeting the identified determinants of immunization provider behaviour.

Background: Although comprising up to 80% of the commercial sex industry in Canada, indoor female sex workers (FSW) are generally not represented in research because they are a hidden population and difficult to access., Objectives: This paper describes a community-academic partnership model that was established to gain access to, deliver outreach services to, and conduct community-based research with the indoor commercial sex industry in four cities in British Columbia., Methods: The project employed an ongoing community consultation, peer-delivered approach to reaching this overlooked segment of the commercial sex industry. Peers (former and current FSW) were hired, trained, and supported as outreach workers and participated in the development, implementation, and evaluation of the project. Outreach teams visited sex establishments to deliver harm reduction materials and provide education, support, and referrals. The teams developed rapport with establishment managers and staff to facilitate research recruitment and data collection. The community team leader met with managers in targeted business to describe the study and elicit permission to recruit workers. The team leader conducted in-person interviews with consenting FSW., Observations: During the first 2 years of the project, more than 50 sex establishments were visited by outreach teams and 37 allowed repeat visits. Research interviews have been conducted with 49 FSW in seven establishments from four cities., Conclusions: Although the high cost in terms of time and resources must be recognized, this project represents a successful research and outreach model that permits access to the hidden commercial sex industry.

Background: We undertook a study to examine the fertility intentions and reproductive health issues of women living with HIV in a broad-based sample in British Columbia, Canada., Methods: Between November 2003 and December 2004, we invited women with HIV at all HIV clinics and AIDS service organizations in the province of British Columbia, Canada, to complete the survey instrument 'Contraceptive Decisions of HIV-positive Women'. Logistic regression analysis was conducted to calculate adjusted odds ratios to identify factors that may be significant predictors of the intention of women living with HIV to have children., Results: Of the 230 surveys completed, 182 women (79.1%) were of reproductive age (

Background: Lifetime protection against pertussis has been adopted as a goal of immunization programs in Canada. To anticipate adult coverage with a combined product containing tetanus (T) and diphtheria (d) toxoids and acellular pertussis (aP) vaccine as a booster dose, we conducted a survey of households in British Columbia, Canada., Methods: In a random telephone survey involving 800 adults, 25 years of age and older, we assessed current behaviors related to adult Td immunization and beliefs regarding pertussis vaccine under various scenarios relevant to adult decision-making., Results: Forty-five percent of participants reported having received tetanus vaccine within the previous 10 years; this rate was lowest amongst elderly persons 65 years of age or more (28%). On multi-variate analysis, being up-to-date with tetanus immunization was independently associated with belief that an adult should be immunized against tetanus and perception that tetanus is life-threatening and inversely associated with being elderly. At baseline, 59% of respondents indicated willingness to receive pertussis immunization if provided free; this increased to 76% following sequential information about communicability and severity of pertussis illness and safety, efficacy and convenience of vaccine and up to 87% if accompanied by physician or nurse recommendation. Sixty-three percent of adults indicated they would receive the vaccine if required to pay $40.00 (Cdn) for it., Conclusions: Personal risk perception, public funding and physician recommendation are important to adults when considering tetanus and pertussis immunization. These factors may be relevant as immunization programs are expanded to include more adults generally.

Since the late 1980s, several HIV-specific quality of life instruments have been developed; however, little testing has been done in terms of their validity and reliability for HIV-infected women. The purpose of this study was to test the content validity, concurrent validity, internal consistency, and test-retest reliability of the Multidimensional Quality of Life Questionnaire for Persons with HIV/AIDS (MQOL-HIV) in a sample of 85 HIV-infected women. The MQOL-HIV is a 40-item scale comprised of 10 dimensions. Most of the items and all of the domains were determined content valid but revision of some of the items and domains is recommended. Concurrent validity was measured between the MQOL-HIV and the MOS-HIV and ranged from 0.51-0.81 between similar domains. Of the 10 domains and the entire instrument, 7 had a Cronbach's alpha over 0.70 (range 0.43-0.92). Eight domains and the entire instrument achieved test-retest correlation coefficients over 0.70 (range 0.60-0.96). Although some revision may make the scale more content-valid for HIV-infected women, given due care in the interpretation of results, the MQOL-HIV can be used with female populations in its current form.
