    Abstract:
    BACKGROUND: The optimal management of patients with suspected biliary obstruction remains unclear, and includes the possible performance of magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP). OBJECTIVES: To complete a cost analysis based on a medical effectiveness randomized trial comparing an ERCP-first approach with an MRCP-first approach in patients with suspected bile duct obstruction. METHODS: The management strategies were based on a medical effectiveness trial of 257 patients over a 12-month follow-up period. Direct and indirect costs were included, adopting a societal perspective. The cost values are expressed in 2012 Canadian dollars. RESULTS: Total per-patient direct costs were Can$3547 for ERCP-first patients and Can$4013 for MRCP-first patients. Corresponding indirect costs were Can$732 and Can$694, respectively. Causes for differences in direct costs included a more frequent second procedure and a greater mean number of hospital days over the year in patients of the MRCP-first group. In contrast, it is the ERCP-first patients whose indirect costs were greater, principally due to more time away from activities of daily living. Choosing an ERCP-first strategy rather than an MRCP-first strategy saved on average Can$428 per patient over the 12-month follow-up duration; however, there existed a large amount of overlap when varying total cost estimates across a sensitivity analysis range based on observed resources utilization. CONCLUSIONS: This cost analysis suggests only a small difference in total costs, favoring the ERCP-first group, and is principally attributable to procedures and hospitalizations with little impact from indirect cost measurements.
