Counts of mortality and morbidity based on routinely collected national datasets have undercounted Māori, the indigenous people of New Zealand. To correct for the undercount, when estimating fatal and serious non-fatal injury incidence, the 'ever-Māori' method has been used. This study sought to determine how well the ever-Māori method corrects for the undercount.
Trends in frequencies and age-standardised rates for fatal injury indicators were compared using: (a) ever-Māori classification; (b) New Zealand Census Mortality Study adjustment ratios applied to Total Māori counts from the Mortality Collection; and (c) Total Māori counts from the Mortality Collection. For serious non-fatal injury, trends using ever-Māori were compared with Total Māori from hospital discharge data.
The absolute number of injuries attributable to Māori varied depending on the method used to adjust for ethnicity status, but trends over time were comparable.
At present, there is no optimal method for adjusting for the undercount of Māori in routinely collected health databases. Reassuringly, trends in fatal and serious non-fatal injury are similar across the methods of adjusting for the undercount.
基于常规收集的国家数据集计算的死亡率和发病率统计数据低估了毛利人，毛利人是新西兰的土著居民。为了纠正这种低估，在估计致命和严重非致命伤害发生率时，使用了“一直是毛利人”的方法。本研究旨在确定“一直是毛利人”的方法在多大程度上纠正了这种低估。
使用以下方法比较致命伤害指标的频率和年龄标准化率趋势：（a）一直是毛利人分类；（b）新西兰人口普查死亡率研究调整比率应用于死亡率收集的毛利人总数；以及（c）死亡率收集的毛利人总数。对于严重非致命伤害，使用“一直是毛利人”的趋势与来自医院出院数据的毛利人总数进行了比较。
归因于毛利人的伤害绝对数量取决于用于调整族裔地位的方法，但随着时间的推移，趋势是可比的。
目前，在常规收集的健康数据库中，没有调整毛利人低估的最佳方法。令人欣慰的是，纠正低估的方法在致命和严重非致命伤害方面的趋势是相似的。
