The revenue generated from clinical chemistry and hematology laboratory services as determined using activity-based costing (ABC) model.

Abstract

Background The rapid and continuous growth of health care cost aggravates the frequently low priority and less attention given in financing laboratory services. The poorest countries have the highest out-of-pocket spending as a percentage of income. Higher charges might provide a greater potential for revenue. If fees raise quality sufficiently, it can enhance usage. Therefore, estimating the revenue generated from laboratory services could help in capacity building and improved quality service provision.Methods Panel study design was used to determine revenue generated from clinical chemistry and hematology services at Tikur Anbessa Specialized Teaching Hospital, Addis Ababa, Ethiopia. Activity-Based Costing (ABC) model was used to determine the true cost of tests performed from October 2011 to December 2011 in the hospital. The principle of Activity-based Costing is that activities consume resources and activities consumed by services which incur the costs and hence service takes the cost of resources. All resources with costs are aggregated with the established casual relationships. The process maps designed was restructured in consultation with the senior staffs working and/or supervising the laboratory and pretested checklists were used for observation. Moreover, office documents, receipts and service bills were used while collecting data. The amount of revenue collected from services was compared with the cost of each subsequent test and the profitability or return on investment (ROI) of services was calculated. Data were collected, entered, cleaned, and analyzed using Microsoft Excel 2007 software program and Statistical Software Package for Social Sciences version 19 (SPSS). Paired sample t test was used to compare the price and cost of each test. P-value less than 0.05 were considered as statistically significant.ResultA total of 25,654 specimens were analyzed during 3 months of regular working hours. The total numbers of clinical chemistry and hematology tests performed during the study period were 45,959 (66.1 %) and 23,570 (33.9 %), respectively. Only 274, 386 (25.3 %) Ethiopian Birr (ETB) was recovered from the total cost of 1,086,008.09 ETB incurred on clinical chemistry and hematology laboratory tests. The result showed that, about 133,821 (12.32 %) ETB was revenue not collected from out-of-pocket payments that was paid for the services as a result of under pricing. The result showed that 18 out of 20 laboratory tests were under priced. The cost burden related to free Anti Retro-viral Therapy (ART) services was 285,979.82 (26.3 %) ETB.ConclusionThe cost per test estimated was significantly different to the existing price. About 90 % of the tests were under priced. This information could warn the hospital to reconsider resetting prices of these tests profitability ration less than 1. The revenue collected could help to build capacity, upscale quality, and sustainable service delivery.
