How Much Does Management of an Asthma-Related Event Cost in a Malaysian Suburban Hospital?

Abstract

Background: Patients with asthma need long-term management to maintain optimal control. In addition to routine maintenance, urgent visits and hospitalizations may be required, as these patients are prone to acute exacerbations. The aim of this study was to estimate the costs of maintenance and acute exacerbation managements in patients with asthma in a suburban public hospital in Malaysia.

Methods: An activity-based microcosting approach was applied to estimate the unit cost of events from the hospital's perspective. First, activities and resources that were involved in each cost center were identified and valued against a suitable form of unit. Thereafter, the mean cost of each resource per event was calculated by dividing the product of the quantity of the resource used and the unit cost of the resource by the number of events. The mean cost per event was the sum of the cost of resources for all cost centers involved. The costs were expressed in 2014 US dollars ($) and Malaysian Ringgit (RM).

Results: Data were collected from 15 maintenance, 20 acute exacerbation, and 50 hospitalization events. The mean (±SD) cost of maintenance management was $48.04 (±10.10); RM154.68 (±32.52). The cost of acute exacerbation management in the Emergency Department was $13.50 (±2.21), RM43.46 (±7.10); and in the medical ward, the cost was $552.13 (±303.41), RM1777.86 (±976.98), per hospitalization event.

Conclusion: The microcosting of management of asthma-related events provides more accurate estimates that could be used in local economic studies. However, its possible limited generalizability to other types of health care settings in Malaysia needs to be kept in mind.
