Background:
Emergency surgery increases the risk of a retained surgical sponge (RSS) by 9-fold. In most cases, surgical counts are falsely reported as correct. We hypothesized that the institutional costs resulting from a RSS would make routine intraoperative radiography (IOR) more cost-effective than surgical counts in preventing RSS after emergent open cavity cases.
Methods:
A cost-effectiveness analysis was performed to compare routine IOR with surgical counts after emergent open cavity operations. Parameter estimates were obtained from the literature, expert opinion via a standardized survey, and existing institutional data.
Results:
Routine IOR was the preferred strategy ($705 vs $1155 per patient) under the assumptions of the base case. The surgical count strategy was dominated by the institutional costs incurred after a RSS. Routine IOR was preferential as long as the sensitivity of surgical counts was less than 98% and the legal fees were more than $44,000 per case of RSS.
Conclusions:
Routine IOR is a simple, cost-effective option to reduce the occurrence of this preventable medical error. Institutional costs and legal fees associated with RSS dominate the cost of the surgical count strategy, making routine IOR a more cost-effective strategy than surgical counts given the best available parameter estimates.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
