新西兰医疗系统正面临严峻的护士人手不足危机。在2022年的独立评审中，83%的3366名一线护士表示患者在人手不足班次中未获得完整护理1。人手不足的情况持续恶化，2021年有23%的班次存在人员不足，到2022-2024年这一比例上升至38%1。针对外科病房的数据更为令人担忧，在2022-2024年间对94个新西兰外科病房的223415例手术收治情况的分析显示，43.5%的班次护理小时数少于患者评估所需1。
护士人手不足对患者预后造成直接威胁。研究证实，每减少一名护士，术后90天内死亡率增加13%，并发症和抢救失败率各增加7%1。消除现有人手不足需增加166名护士（141个全职岗位），这一举措可减少年均182例术后死亡1。为应对这一危机，新西兰卫生部门正考虑采取立法手段规定最低护患比例。国际经验表明该举措行之有效，昆士兰州2016年立法规定日班和午班至少1名护士对应4名患者，夜班为1:7，随后医院护士高度倦怠率降低24%，工作不满意度降低27%1。加州在2004年实施类似法律后，患者每天获得比其他州患者多2-3小时护理1。
New Zealand is grappling with a critical shortage of nursing staff that has become a focal point in electoral debate, with researchers and policymakers increasingly advocating for legislated minimum patient-to-nurse ratios.1 An independent review in 2022 found that 83% of 3,366 frontline nurses reported patients did not receive complete care during understaffed shifts.1 The problem has intensified significantly, with understaffed shifts rising from 23% in 2021 to 38% between 2022 and 2024.1
The consequences of inadequate nursing levels have proven measurable and severe. Analysis of 223,415 surgical cases across 94 New Zealand operating rooms between 2022 and 2024 revealed that 43.5% of shifts fell short of the nursing hours required by patient acuity assessments.1 Research demonstrates that losing a single nurse correlates with a 13% increase in patient mortality within 90 days post-operation, alongside 7% increases in both complication rates and resuscitation failures.1 Addressing current understaffing would require adding 166 nurses (equivalent to 141 full-time positions), potentially preventing 182 post-operative deaths annually.1
International precedent suggests legislative solutions can improve both patient outcomes and workforce conditions. Queensland implemented mandatory nurse-to-patient ratios in 2016, requiring at least one nurse per four patients during day and afternoon shifts, and one per seven during night shifts.1 This reform yielded measurable benefits, reducing high burnout rates among hospital nurses by 24% and job dissatisfaction by 27%.1 California's 2004 legislation similarly advanced patient care, resulting in patients receiving 2 to 3 additional hours of nursing care daily compared to other states.1 New Zealand's health authorities are currently evaluating whether to adopt comparable ratio-based staffing models.1
