Auckland University research links nurse shortages to increased surgical deaths

Research from Auckland University indicates that nurse shortages in post-operative care in New Zealand may lead to approximately 182 preventable deaths annually. The study analyzed data from over 200,000 patients and 223,000 operations conducted between 2022 and 2024, linking surgical outcomes to nursing staffing levels.

Findings show that approximately 45% of shifts were understaffed, with 28% falling below predefined targets. The research established a direct correlation between staffing levels and patient safety: each reduction of one nurse per shift was associated with a 7% increase in complications, a 7% increase in “failure to rescue” events, and a 13% increase in mortality rates.

Lucy Middleton of the New Zealand Nurses Organisation noted that these findings highlight the human cost of staffing levels being determined by cost-cutting budgets rather than patient requirements, specifically citing the impact of recent recruitment freezes at Te Whatu Ora.
