These researchers developed and applied a systematic method in order to monitor all hospital admissions for infectious and non-infectious diseases in New Zealand from 1989 to 2008. They investigated trends in incidence and distribution by ethnic group and socioeconomic status. Infectious diseases were the largest contributor to hospital admissions of any cause, increasing from 20.5% of acute admissions in 1989-93 to 26.6% in 2004-08. Ethnic and social inequalities were noted for infectious disease risk. In 2004-08, the age-standardised rate ratio was 2.15 for Māori (Indigenous New Zealanders) and 2.35 for Pacific peoples compared with the European and Other groups. The ratio was 2.81 for the most socioeconomically deprived quintile compared with the least deprived quintile. These inequalities have increased substantially in the past 20 years, particularly for Māori and Pacific peoples in the most deprived quintile.
An example of the need to continue collecting and analysing valid, reliable, comparable data for trends, levels and inequalities in order to monitor progress and plan services. More importantly, the findings underscore the fact that social effects are the biggest contributor to these health inequities in New Zealand.
