A population-based study of traumatic brain injury incidence and mechanisms in New Zealand: 2021-2022 compared with 2010-2011.

ABSTRACT:

Background

Monitoring traumatic brain injury (TBI) incidence and epidemiological patterns is important for evidence-based strategic planning, policy, prevention, and resource allocation. We revisited population-based estimates and examined patterns of TBI incidence (all ages, severities) in 2021-2022 compared with 2010-2011 in New Zealand (NZ).

Methods

Examining an urban (Hamilton) and rural (Waikato District) region in NZ (May 2021-April 2022, unintentionally following the start of the COVID-19 pandemic), we calculated crude annual age-, sex-, ethnic-, urban/rural area- and mechanism-specific TBI incidence per 100,000 person-years with 95% Confidence Intervals (CI). Poisson regression was used to derive adjusted Risk Ratios (aRRs) to compare age-standardised rates between s
