The rising demand for colonoscopy raises concerns that M\u0101ori populations could be under\u2010served. This study aimed to compare rates of colonoscopy provision and colonoscopy KPIs between M\u0101ori and New Zealand (NZ) European patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This retrospective comparative study was conducted at Whanganui Hospital (NZ). Consecutive colonoscopies performed between September 2016 and March 2020 were included. Primary outcome was the rate of colonoscopy provision for the population. Secondary outcomes were the colonoscopy completion rate (CCR), colonoscope withdrawal time (CWT), polyp detection rate (PDR) and adenoma detection rate (ADR). Subgroup analysis of ADR in index symptomatic colonoscopies was also performed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 2962 colonoscopies were analysed (385 M\u0101ori; 2577 NZ European). Rates of colonoscopy provision in participants aged \u226540 were significantly lower among M\u0101ori (6.1% versus 9.1%; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.0001). The CCR (<jats:italic>P<\/jats:italic>\u00a0=\u00a01.00), CWT (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.28) and PDR (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.24) were similar. Whilst the ADR in the overall cohort was significantly lower in M\u0101ori (32.7% versus 40.0%; <jats:italic>P<\/jats:italic>\u00a0=\u00a00.028), this was not observed when stratified by 10\u2010year age cohorts. The ADR was similar on subgroup analysis of index symptomatic colonoscopies (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.42).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>This study found inequities in access to colonoscopy services for M\u0101ori compared to NZ European patients. Among those that did receive colonoscopy, there were no differences in colonoscopy quality after age stratification. Improving equity will require the addition of colonoscopy provision rates to other mandatory KPIs and reporting these by ethnicity in all endoscopy units.<\/jats:p><\/jats:sec>","DOI":"10.1111\/ans.16636","type":"journal-article","created":{"date-parts":[[2021,2,18]],"date-time":"2021-02-18T19:18:49Z","timestamp":1613675929000},"page":"1575-1581","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Equity of colonoscopy provision and quality in M\u0101ori and New Zealand Europeans: a comparative retrospective study"],"prefix":"10.1111","volume":"91","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6627-9233","authenticated-orcid":false,"given":"Matthew","family":"Donachie","sequence":"first","affiliation":[{"name":"Department of Surgery, Whanganui Hospital Whanganui District Health Board  Gonville New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sameer","family":"Bhat","sequence":"additional","affiliation":[{"name":"Department of Surgery, Faculty of Medical and Health Sciences The University of Auckland  Grafton New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teri","family":"Whiley","sequence":"additional","affiliation":[{"name":"Department of Surgery, Whanganui Hospital Whanganui District Health Board  Gonville New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wiremu","family":"MacFater","sequence":"additional","affiliation":[{"name":"Department of Surgery, Faculty of Medical and Health Sciences The University of Auckland  Grafton New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6530-2454","authenticated-orcid":false,"given":"Ian P.","family":"Bissett","sequence":"additional","affiliation":[{"name":"Department of Surgery, Faculty of Medical and Health Sciences The University of Auckland  Grafton New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marianne","family":"Lill","sequence":"additional","affiliation":[{"name":"Department of Surgery, Whanganui Hospital Whanganui District Health Board  Gonville New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,2,15]]},"reference":[{"key":"e_1_2_8_2_1","unstructured":"New Zealand Ministry of Health.New Zealand Cancer Registry: Selected Cancers 2015 2016 2017.2019.
