  1. A-Track pilot survey in Regina: Preliminary findings Presented at the RQHR Research Showcase June 19, 2013 Dr. Maurice Hennink Deputy Medical Health Officer Population and Public Health Services

  2. A-Track Surveillance Team

  3. Overview • Background • Survey Implementation • Methodology • Results • Socio-demographics • Sexual behaviour • Injection and non-injection drug use • HIV testing history • History of STBBI • Use of health services and needle exchange programs

  4. Background • Public Health Agency of Canada in collaboration with All Nations Hope AIDS Network, Aboriginal community groups and the Regina Qu’Appelle Health region conducted a behavioural and biological surveillance survey to determine the prevalence of HIV and associated infections, behaviours and socio-demographic factors among Aboriginal populations in Regina. • This survey collected self-reported information on socio-demographic factors and social determinants of health; sexual and drug-use practices; diagnostic testing and treatment for HIV, tuberculosis, and other infections; access to health services; and knowledge of modes of transmission for HIV and other sexually transmitted and blood-borne infections. • The pilot survey was conducted between December 2011 and June 2012.

  5. Trends over time Time T3 prev. T2 prev. T1 prevalence Description of the A-Track system • Repeated cross-sectional surveys at selected sentinel sites (urban/semi-urban) across Canada • Venue-based sampling • Consistent sampling and recruitment strategies over time

  6. Methodology • Anonymous cross-sectional survey with informed consent. • Participants recruited using venue-based sampling methods. • Venues were identified based on geographic clusters and neighborhoods where Aboriginal people mostly reside or socialize. • The target sample size was 1,100. • The dataset was checked for similarities in individual profiles (age and risk behaviours) to exclude duplicate entries.

  7. Methodology • Eligibility criteria • participants be between 15 and 60 years of age, • could speak English, and • could provide informed consent. • Exclusion Criteria • A person who, in the judgement of interviewer, appears intoxicated, or incapacitated due to psychological or cognitive deficit or discomfort or distress and is hence unable to provide informed consent or is incapable of understanding the survey information. • A person who has already participated once in the current survey. • A person who does not self-identify as Aboriginal and who does not meet the age inclusion criteria.

  8. Methodology • Interviewer-administered questionnaires • socio-demographic, • sexual behaviour, • drug use, • history of HIV testing, sexually transmitted infections and tuberculosis, • access to health services • knowledge of HIV • $20 provided for participation. • Questionnaires were administered using a laptop computer and interviewers entered responses directly into the computer during the interview.

  9. Methodology • Participants were asked to provide a finger-prick blood sample and was tested for HIV, HCV (hepatitis C) and syphilis antibodies. • Counseling and HIV antibody testing was made available for participants who were interested in finding out their HIV status. • Community partners involved • having input into how the project will be organized, • part of the analysis and interpretation of data and how the results are distributed.

  10. Ethical Aspects • Anonymous • Informed Consent • Ethics approval was obtained from the Research Ethics Boards for Health Canada/PHAC, Regina Qu’Appelle Health Region, and the University of Regina/First Nations University of Canada.

  11. Limitations • A-Track survey was not population based and used venue-based sampling method to enroll survey participants. This may not reflect all Aboriginal people and their distribution in the population. • A-Track sample included: • A higher proportion of First Nations individuals • A lower proportion of Metis and Inuit people compared to these groups in Regina • Given the better representation of the First Nations peoples in the A-Track survey, survey findings may be more reflective of actual First Nations population living in Regina. • The findings are based on self-reported data (except for sero-prevalence of HIV and HCV) and may be subject to social desirability bias.

  12. Results

  13. Data Collection • Conducted between December 5, 2011 and June 15, 2012. • Total Interviewed 1,071 • Total duplicates 7 • Total available for analysis 1,064 • Total who didn’t provide a Dried Blood Sample 19 (1.8%) • A range of communication activities were implemented to highlight the study among the prospective study population at each venue prior to commencement.

  48. Health care access by health providers/facilities (n=821) Each respondent could select more than one category

  49. Conclusions • The findings highlight some of the critical issues that exist around risk behaviours and the transmission of HIV in the Aboriginal population including: • education levels • history of family separations • correctional services involvement • a high HIV prevalence amongst survey participants, with strong correlation to past or current use of injection drugs • the proportion of participant who were unaware of their HIV infection is higher than the estimated proportion of 25% for the overall Canadian population of people living with HIV • RQHR and service provider agencies can use the information included in this report to better understand local harm reduction needs and to tailor services to prevent increased HIV transmission.

  50. Conclusions • These data represent the best available findings on HIV prevalence and associated factors for First Nations and Métis people in Regina. However, these data cannot be generalized to the overall Aboriginal population of Regina. • The development and implementation process has illustrated many successes in collaboration between public health and community. • Lessons learned will also inform the utility and methodological feasibility of future wider implementation of the A-Track surveys at other off-reserve sentinel sites in Canada • Findings support continued work on the HIV strategy.
