#hauora: Sepsis is placing a growing burden on Aotearoa’s health system

Sepsis is placing a growing burden on Aotearoa’s health system, with new research showing a sharp rise in hospital admissions over the past two decades, and Māori and Pacific communities disproportionately affected.

The study from the University of Otago, Wellington analysed public hospital data between 2000 and 2019, finding admissions for sepsis increased by 78 percent over that period.

Sepsis is a life-threatening condition caused by the body’s extreme response to infection, which can lead to organ failure and death. Researchers say it has had a significant impact on health outcomes in Aotearoa, accounting for tens of thousands of deaths and a notable share of overall mortality.

The findings show stark inequities, with Māori and Pacific peoples far more likely to be hospitalised with sepsis and significantly more likely to die from the condition compared to other groups. People living in the most deprived communities also faced a much higher risk of death.

Infants and older people, particularly those over 70, were among the most vulnerable, although survival rates have improved over time, especially for older patients.

Researchers say the number of cases is likely to keep rising as the population ages and more people live with chronic conditions such as diabetes. They also point to factors like overcrowded housing and wider social inequities as increasing the risk.

Health experts say many cases of sepsis are preventable, and are calling for stronger public health measures, including earlier detection and treatment, better use of antibiotics, and improved awareness.

They also warn that delays in treatment are putting lives at risk, with many patients not receiving care within the critical early window.

There are growing calls for a coordinated national approach, with experts urging the Government to prioritise a comprehensive plan to address sepsis, reduce inequities, and improve outcomes for whānau across the country.
