Tuberculosis transmission in the Indigenous peoples of the Canadian prairies.

SETTING: The prairie provinces of Canada. OBJECTIVE: To characterize tuberculosis (TB) transmission among the Indigenous and non-Indigenous Canadian-born peoples of the prairie provinces of Canada. DESIGN: A prospective epidemiologic study of consecutively diagnosed adult (age ≥ 14 years) Canadian-born culture-positive pulmonary TB cases on the prairies, hereafter termed "potential transmitters," and the transmission events generated by them. "Transmission events" included new positive tuberculin skin tests (TSTs), TST conversions, and secondary cases among contacts. RESULTS: In the years 2007 and 2008, 222 potential transmitters were diagnosed on the prairies. Of these, the vast majority (198; 89.2%) were Indigenous peoples who resided in either an Indigenous community (135; 68.2%) or a major metropolitan area (44; 22.2%). Over the 4.5-year period between July 1st, 2006 and December 31st 2010, 1085 transmission events occurred in connection with these potential transmitters. Most of these transmission events were attributable to potential transmitters who identified as Indigenous (94.5%). With a few notable exceptions most transmitters and their infected contacts resided in the same community type. In multivariate models positive smear status and a higher number of close contacts were associated with increased transmission; adjusted odds ratios (ORs) and 95% confidence intervals (CIs), 4.30 [1.88, 9.84] and 2.88 [1.31, 6.34], respectively. Among infected contacts, being Indigenous was associated with disease progression; OR and 95% CI, 3.59 [1.27, 10.14] and 6.89 [2.04, 23.25] depending upon Indigenous group, while being an infected casual contact was less likely than being a close contact to be associated with disease progression, 0.66 [0.44, 1.00]. CONCLUSION: In the prairie provinces of Canada and among Canadian-born persons, Indigenous peoples account for the vast majority of cases with the potential to transmit as well as the vast majority of infected contacts. Active case finding and preventative therapy measures need to focus on high-incidence Indigenous communities.

Improving the Standards-Based Management-Recognition initiative to provide high-quality, equitable maternal health services in Malawi: an implementation research protocol.

BACKGROUND: The Government of Malawi is seeking evidence to improve implementation of its flagship quality of care improvement initiative-the Standards Based Management-Recognition for Reproductive Health (SBM-R(RH)). OBJECTIVE: This implementation study will assess the quality of maternal healthcare in facilities where the SBM-R(RH) initiative has been employed, identify factors that support or undermine effectiveness of the initiative and develop strategies to further enhance its operation. METHODS: Data will be collected in 4 interlinked modules using quantitative and qualitative research methods. Module 1 will develop the programme theory underlying the SBM-R(RH) initiative, using document review and in-depth interviews with policymakers and programme managers. Module 2 will quantitatively assess the quality and equity of maternal healthcare provided in facilities where the SBM-R(RH) initiative has been implemented, using the Malawi Integrated Performance Standards for Reproductive Health. Module 3 will conduct an organisational ethnography to explore the structures and processes through which SBM-R(RH) is currently operationalised. Barriers and facilitators will be identified. Module 4 will involve coordinated co-production of knowledge by researchers, policymakers and the public, to identify and test strategies to improve implementation of the initiative. POTENTIAL IMPACT: The research outcomes will provide empirical evidence of strategies that will enhance the facilitators and address the barriers to effective implementation of the initiative. It will also contribute to the theoretical advances in the emerging science of implementation research.

Comparing antiretroviral treatment outcomes between a prospective community-based and hospital-based cohort of HIV patients in rural Uganda.

BACKGROUND: Improved availability of antiretroviral therapy in sub-Saharan Africa is intended to benefit all eligible HIV-infected patients; however in reality antiretroviral services are mainly offered in urban hospitals. Poor rural patients have difficulty accessing the drugs, making the provision of antiretroviral therapy inequitable. Initial tests of community-based treatment programs in Uganda suggest that home-based treatment of HIV/AIDS may equal hospital-based treatment; however the literature reveals limited experiences with such programs. THE RESEARCH: This intervention study aimed to; 1) assess the effectiveness of a rural community-based ART program in a subcounty (Rwimi) of Uganda; and 2) compare treatment outcomes and mortality in a rural community-based antiretroviral therapy program with a well-established hospital-based program. Ethics approvals were obtained in Canada and Uganda. RESULTS AND OUTCOMES: Successful treatment outcomes after two years in both the community and hospital cohorts were high. All-cause mortality was similar in both cohorts. However, community-based patients were more likely to achieve viral suppression and had good adherence to treatment. The community-based program was slightly more cost-effective. Per capita costs in both settings were unsustainable, representing more than Uganda's Primary Health Care Services current expenditures per person per year for all health services. The unpaid community volunteers showed high participation and low attrition rates for the two years that this program was evaluated. CHALLENGES AND SUCCESSES: Key successes of this study include the demonstration that antiretroviral therapy can be provided in a rural setting, the creation of a research infrastructure and culture within Kabarole's health system, and the establishment of a research collaboration capable of enriching the global health graduate program at the University of Alberta. Challenging questions about the long-term feasibility and sustainability of a community-based ARV program in Uganda still remain. THE PARTNERSHIP: This project is a continuation of previous successful collaborations between the School of Public Health of Makerere University, the School of Public Health of University of Alberta, the Kabarole District Administration and the Kabarole Research and Resource Center.

Public knowledge and attitudes toward HIV/AIDS and antiretroviral therapy in Kabarole district, western Uganda.

A study on knowledge about HIV/AIDS and antiretroviral therapy (ART) was conducted in the general population of a rural district in western Uganda. Three hundred seventy-two participants were selected by random cluster sampling and interviewed with an interview-administered questionnaire. Data were analyzed quantitatively with descriptive, univariate and linear multivariate statistical analysis with the knowledge score about ART as the dependent variable. The results indicate that the mean knowledge was 7.7 in a scale from 0 to 13. Predictor for better ART knowledge was a higher educational status of the participants. Older participants over 50 years were less ART knowledgeable. Only 19% of the participants have been tested for HIV. The conclusions are that the ART knowledge in this population is remarkably high which is reaffirming and important for achieving a high adherence to ART. Of concern is the low proportion of persons tested for HIV in this general population. Kabarole district seems to be receptive and capable for intensifying HIV testing which is a precondition for the ART roll-out.

Patterns of injury in children: a population-based approach.

OBJECTIVE: We describe the frequency and patterns of injury affecting 96 359 children between 0 and 10 years old and living in Alberta, Canada. DESIGN: This population-based, longitudinal study involved children born in the 3 fiscal years of April 1, 1985 to March 31, 1988, recruited before age 1, and who remained in the study until at least age 5. We used the International Classification of Diseases, Ninth Revision, Clinical Modification chapter-17 diagnostic codes provided by physicians. Codes were grouped into 17 categories; injury episodes were calculated, and age- and gender-specific incidence rates for each category were calculated. The age, pattern, times of greatest risk, and the effect of gender on the type and incidence of injury were determined. SETTING: Health care administrative data were obtained from all fee-for-service health care venues in Alberta between April 1, 1985 and March 31, 1998 providing services to children registered with the Alberta Health Care Insurance Plan and otherwise meeting entrance criteria. RESULTS: Nearly 84% of children received care for an injury during the study period, and in any given year approximately 21% of the population studied had at least 1 injury. Repeat injury was common (73%), and boys were more likely than girls to be injured and to have repeat injury. The most common injuries were dislocations and sprains, open wounds, and superficial injuries and contusions. Burns, poisoning, intracranial injury, and foreign bodies were the next most common, and fractures were least common. Approximately 10% of injuries were multiple-category injuries. Rates varied greatly by injury category, age, and gender. Hospitalization rates varied in a similar manner and commonly accounted for approximately 10% of all services. Males were most likely to have an injury, and aboriginal children or children who had received welfare at some time were at greatest risk. CONCLUSIONS: Administrative data can be used to estimate the incidence of injury in a pediatric population. Distinct patterns of injury occur at different ages. Recurrent injury is common. Almost identical proportions of injury (46%) are treated in emergency departments and physicians' offices.

Citizen participation in health decision-making: past experience and future prospects.

Every couple of decades governments decide that they need to involve citizens more in public decision-making processes. The significant changes that have occurred over the past decade, including a growing loss of faith in the traditional institutions of government, have once again prompted political decision-makers to explore options for enhanced citizen participation. In the health care sector, reforms occurring during the 1990s were couched in terms such as "enhanced responsiveness," "improved accountability," and "increased citizen participation." In the new millennium, governments and regional health authorities have been relatively silent on this issue. As has been the case in the past, a wide range of opinions exist about what citizen participation is and how governments should proceed. Without either conceptual clarity or practical direction, governments have been slow to articulate what they hope to achieve or how they intend to get there. The purpose of this paper is to examine the concept of citizen participation within the context of a series of basic questions from which decision-makers might draw some policy relevance. Rather than taking a particular disciplinary perspective (i.e. health promotion), the authors have chosen to review a broad spectrum of existing literature to provide a better understanding of what is known about citizen participation, both good and bad. As such, the paper is meant to be a point of departure for an informed discussion of the possibilities for improved citizen participation in health (care) decision-making.
