Managing Matajoosh: determinants of first Nations' cancer care decisions.

BACKGROUND: Accessing cancer treatment requires First Nation peoples living in rural and remote communities to either commute to care, or to relocate to an urban centre for the length or part of the treatment. While Canadians living in rural and remote communities must often make difficult decisions following a cancer diagnosis, such decisions are further complicated by the unique policy and socio-historical contexts affecting many First Nation peoples in Canada. These contexts often intersect with negative healthcare experiences which can be related to jurisdictional confusion encountered when seeking care. Given the rising incidence of cancer within First Nation populations, there is a growing potential for negative health outcomes. METHODS: The analysis presented in this paper focuses on the experience of First Nation peoples' access to cancer care in the province of Manitoba. We analyzed policy documents and government websites; interviewed individuals who have experienced relocation (N = 5), family members (N = 8), healthcare providers and administrators (N = 15). RESULTS: Although the healthcare providers (social workers, physicians, nurses, patient navigators, and administrators) we interviewed wanted to assist patients and their families, the focus of care remained informed by patients' clinical reality, without recognition of the context which impacts and constrains access to cancer care services. Contrasting and converging narratives identify barriers to early diagnosis, poor coordination of care across jurisdictions and logistic complexities that result in fatigue and undermine adherence. Providers and decision-makers who were aware of this broader context were not empowered to address system's limitations. CONCLUSIONS: We argue that a whole system's approach is required in order to address these limitations.

Mammography rates for breast cancer screening: a comparison of First Nations women and all other women living in Manitoba, Canada, 1999-2008.

INTRODUCTION: First Nations (FN) women historically have low rates of preventive care, including breast cancer screening. We describe the frequency of breast cancer screening among FN women living in Manitoba and all other Manitoba (AOM) women after the introduction of a provincial, organized breast screening program and explore how age, area of residence, and time period influenced breast cancer screening participation. METHODS: The federal Indian Registry was linked to 2 population-based, provincial data sources. A negative binomial model was used to compare breast cancer screening for FN women with screening for AOM women. RESULTS: From 1999 through 2008, 37% of FN and 59% of AOM women had a mammogram in the previous 2 years. Regardless of area of residence, FN women were less likely to have had a mammogram than AOM women (relative rate [RR] = 0.69 in the north, RR = 0.55 in the rural south, and RR = 0.53 in urban areas). CONCLUSIONS: FN women living in Manitoba had lower mammography rates than AOM women. To ensure equity for all Manitoba women, strategies that encourage FN women to participate in breast cancer screening should be promoted.

Factors associated with human papillomavirus infection detected by polymerase chain reaction among urban Canadian aboriginal and non-aboriginal women.

OBJECTIVES: To determine the prevalence and correlates of human papillomavirus (HPV) infection among women attending an ethnically mixed, predominantly low-income, inner-city primary care clinic. STUDY DESIGN: Cross-sectional survey (N = 1,477). Demographic, behavioral, and reproductive history data were collected by questionnaire. Cervical swabs were analyzed for gonorrhea and chlamydial infections, abnormal cytology, and HPV infection assessed by PCR followed by hybridization for types 6, 11, 16, 18, 31, 33, and 35. RESULTS: Human papillomavirus was detected in 33% of specimens, with no significant difference between Aboriginal (AB) and non-Aboriginal women. Adjusting for AB status, HPV infection was associated with marital status, condom use, number of sexual partners (last year and lifetime), age at first sexual intercourse, a history of sexual abuse, and current abnormal Papanicolaou (Pap) smear. In multivariate analyses excluding abnormal Pap smear as an independent variable, marital status and the number of lifetime sexual partners were found to be significant independent predictors of HPV infection. Comparing individuals with 20+ lifetime sexual partners and those with 1 or fewer partners, the odds ratio (OR) for HPV infection was 1.90 (95% confidence interval [CI] 1.66-2.17) among AB women and 1.54 among non-AB women (95% CI 1.36-1.73). The OR for infection with HPV types 6 and 11 was 1.39 (95% CI 1.22-1.58), whereas for the high oncogenic risk types of 16, 18, 31, 33, and 35, the OR was 1.82 (95% CI 1.65-2.01). CONCLUSIONS: No differences were found between AB and non-AB women in the detection of HPV DNA, despite the higher risk for cervical cancer and the prevalence of recognized behavioral and reproductive risk factors among AB women. This study also indicates that the association of sexual activity with HPV infection holds true for both high- and low-oncogenic HPV types.
