The development of a method for comparative costing of individual intensive care units. The Intensive Care Working Group on Costing.

Intensive care is one of the most costly areas of hospital care. Unfortunately, because of the diversity of case mix, costing intensive care is difficult. Many described costing methods previously are limited by being cumbersome, laborious to apply and expensive. The aim of this study was to develop a method for costing intensive care which can be applied with ease but facilitate meaningful cost comparisons between intensive care units. The method developed was based on cost blocks where the major components were identified and costed in a 'top-down' manner. Using strict definitions, the cost blocks attempted to measure the costs of equipment, estates, nonclinical support services (such as hospital management costs), clinical support services (such as physiotherapy, laboratory services), consumables (such as drugs, fluids and disposables) and staff. The study found that clinical support services, consumables and staff costs accounted for approximately 85% of the total costs.
