Cost containment: the Pacific. New Zealand

Area of Science:

• Health Services Research
• Critical Care Medicine
• Health Economics

Background:

• New Zealand's healthcare system is government-funded and undergoing reform.
• Healthcare spending is 7.4% of GDP, with limited Intensive Care Unit (ICU) beds (0.9% of total beds).
• ICU bed numbers decreased by 5% between 1989-1992.

Purpose of the Study:

• To analyze the resource allocation and clinical practices in New Zealand's Intensive Care Units (ICUs).
• To understand how limited ICU resources influence patient care and technology adoption.

Main Methods:

• Analysis of healthcare spending, ICU bed availability, and historical trends in bed numbers.
• Examination of clinical practices, including patient selection, therapy limitation, and technology use.

Main Results:

• Clinicians manage limited ICU resources by preventing severe illness, carefully vetting admissions, and reducing length of stay.
• Therapy limitation and withdrawal are established practices.
• Physicians are conservative with new technology but value quality and efficiency.

Conclusions:

• New Zealand ICUs operate with resource constraints, necessitating careful management and established practices for therapy limitation.
• Efficient resource utilization and knowledge diffusion are key features, despite conservative technology adoption.
