Comparative Analysis of Costing Methods for Magnetic Resonance Imaging in a Tertiary Care Teaching Hospital: An Observational Study

Abstract

Background: Health-care costs, often determined through outdated methods, fail to capture the true costs of care delivery. Traditional costing methods in the health-care sector have proven insufficient, leading to potential revenue losses and increased patient out-of-pocket expenses. Activity-based costing (ABC) and time-driven ABC (TDABC) offer alternative approaches to cost calculation, aiming for a more accurate reflection of resource consumption. Methodology: This descriptive observational study was conducted in the magnetic resonance imaging (MRI) center of a tertiary care teaching hospital, focusing on a single noncontrast MRI scan costing. Direct observations and record reviews, including standard operating procedures, policy letters, financial documents, and miscellaneous records, were employed. Results: Using traditional costing, the unit cost of an MRI scan was calculated at INR 1291.51. ABC yielded a unit cost of INR 3613.77, while TDABC resulted in a unit cost of INR 2764.39. A comparison between the three costing methods revealed potential revenue losses with traditional costing. In contrast, TDABC appeared to strike a balance between financial prudence and reduced patient out-of-pocket expenses. Conclusion: The study emphasizes the significance of understanding true costs in health-care delivery. The results advocate for the adoption of TDABC as a favorable compromise, enabling the hospital to retain revenue without burdening patients with additional costs. Notably, the study highlights the necessity for a granular understanding of true costs for successful transitions from volume to value in health care.
