Background: First of all, in method of Activity Based Costing (ABC), activities identify and then direct and overhead costs associated with each activity calculate based on allocation methods. This study aimed at estimating cost of Hematology ward based on method of Activity Based Costing in Imam Reza hospital of Tehran city in 2014.
Materials and Methods: This study was an applied and cross-sectional one. Specific and overhead data cost of Hematology ward collected using activity-based costing method in Imam Reza hospital in the first semester of 2014. In order to allocate the costs of Hematology ward services, first, allocation bases were determined and then direct allocation method utilized to estimate the costs.
Results: The study findings indicated that costs of each CBC Test, Malaria slide, Cell Count of Biological Fluids and Reticulocyte count were 72673, 64678, 48509 and 48508 Rials respectively. Among the cost centers, the highest costs belonged to buildings depreciation (overhead) (714117127 Rials), Hematology personneles (4182223581 Rials (and materials and supplies costs (110635349 Rials), respectively.
Conclusions: Based on study results, estimated costs differed from tariffs and only Cell Count of Biological Fluids tariff is greater than the estimated cost, the rest of the tests had fewer tariffs than estimated cost which cause laboratory financial loss. At first, in order to control or increase productivity, it is essential to focus on building depreciation costs (e.g. increasing the number of tests) and then should be plan properly to increase manpower productivity of materials and supplies. All tariffs were estimated higher than the estimated cost without building depreciation cost.
