Abstract

Cancer Health services Health system Indigenous people Meta-analysis Social determinants Surgery Systematic review
Background: As cancer incidence increases globally, so does the prevalence of cancer among Indigenous peoples. Indigenous peoples face significant barriers to healthcare, including access to and uptake of surgery. To date, the synthesis of access to and uptake of surgery for Indigenous peoples living with cancer has not yet been reported. Methods: We conducted a systematic literature review and meta-analysis of access to and uptake of surgery for Indigenous peoples in Canada, Australia, New Zealand, and the United States. Five databases were searched to identify studies of Indigenous adults with cancer and those who received surgery. The Joanna Briggs Institute critical appraisal tools were used to assess the quality and inclusion of articles. Random effect meta-analyses were conducted to estimate the pooled prevalence of surgery in Indigenous people with cancer. Findings: Of the 52 studies in the systematic review, 38 were included in the meta-analysis. The pooled prevalence of surgery in Indigenous people with cancer was 56.2% (95% confidence interval (CI): 45.4–66.7%), including 42.8% (95% CI: 36.3–49.5%) in the Native Hawaiian population, 44.5% (95% CI: 38.7–50.3%) in the Inuit and 51.5% (95%CI: 36.8–65.9%) in Aboriginal and Torres Strait Islander people. Overall, Indigenous people received marginally less cancer surgery than non-Indigenous people (3%, 95% CI: 0–6%). Indigenous people were 15% (95% CI: 6–23%) less likely to receive surgery than non-Indigenous people for respiratory cancers. Remoteness, travel distance, financial barriers, and long waiting times to receive surgery were factors cited as contributing to lower access to surgery for Indigenous people compared to non-Indigenous people. Interpretation: Efforts to improve access and use of cancer services and surgery for Indigenous peoples should be multilevel to address individual factors, health services and systems, and structural barriers. These determinants need to be addressed to expedite optimal care for Indigenous peoples, especially those living in outer metropolitan areas.
