RE Official Information Act request WCDHB 9339
I refer to your email dated 22 August 2019 requesting the following information under the Official Information Act from West Coast DHB related to the percentages of Maori who have had colonoscopies. Specifically:
- It would be greatly appreciated if your IT or data analysis team at the District Health Board could provide the Society with data on the percentages of Maori who have had colonoscopy in the past year (or financial year if that is easier to work out), as compared with the percentage of Māori in the local population.
Response:
There were a total of 341 individual patients who had a colonoscopy at West Coast DHB in 2018/19, of whom 7.33% had identified as being Maori.
The overall resident population of Maori on the West Coast in 2018/19 is 3,970, or 12.0% of the overall population in the West Coast DHB district, based on the Statistics New Zealand population projection estimates for 2018/19.
However, over three quarters of colonoscopies are performed on people over 40 years of age. The West Coast Maori population for over 40 year olds in 2018/2019 is 950 or 6.8% of the total population over 40.
I trust that this satisfies your interest in this matter.
Please note that this response, or an edited version of this response, may be published on the West Coast DHB website after your receipt of this response.
