Dear Ministry of Health,

I am writing to request information under the Official Information Act 1982, concerning traumatic brain injury (TBI) admissions to hospitals in New Zealand between the years 1985 and 1987.

Specifically, I would like to request the following data:

The total number of TBI admissions to hospitals during the years 1985, 1986, and 1987.
The breakdown of TBI admissions by age group (e.g., under 18, 18-24, 25-34, 35-44, 45-54, 55-64, 65 and over) for each year.
The breakdown of TBI admissions by gender for each year.
The primary causes of TBI (e.g., falls, motor vehicle accidents, sports injuries, assaults) for each year, with the number of cases for each cause.
The severity of TBIs (e.g., mild, moderate, severe) for each year, with the number of cases for each severity level.
The average length of hospital stay for TBI patients for each year.
The number of TBI-related fatalities for each year.
Please provide the information in electronic format, preferably in a spreadsheet format such as Excel or CSV. If any of the requested information is unavailable or cannot be provided, kindly inform me of the reasons for its unavailability and, if possible, suggest alternative data sources that may have the requested information.

I understand that under the Official Information Act 1982, I should receive a response to my request within 20 working days. If my request is likely to take longer to process, please let me know as soon as possible.

Thank you for your assistance in providing this information.

Yours faithfully,

Amy Ferguson
