A baseline assessment of current practice of use of hospital supplies in 2 surgical theatres was carried out. An initiative to preduce preventable waste costs was then initiated, involving all stakeholders to embed good practice. Finally an unannounced audit was conducted to evaluate the success of the initiative. The results showed that the initiative had been adopted and there was a clear reduction in preventable waste costs.
