Background: Video-assisted thoracoscopic surgery (VATS) is a practical resource in the management of traumatic hemothorax. However, it carries inherent risks and should be mobilized cost-effectively. In this study, we investigated the ideal VATS timing using cost analysis.
Methods: 617 cases of unilateral traumatic hemothorax from 2012 to 2022 were identified in our trauma database. We extracted encounter cost, length of stay (LOS), and operative cost information. Using Kruskal-Walli's test, we compared the cost and LOS for patients who underwent VATS or continued nonoperative management in the first 7 days of admission. Additionally, we computed the daily proportion of patients initially managed nonoperatively but ultimately underwent VATS. P-values <.05 were considered significant.
Results: The median encounter cost of cases managed operatively before hospital day 4 (HD4) was higher than those managed nonoperatively. This difference was $63k on HD2 (P-value .07) and was statistically significant for HD3 (difference of $65k, P-value .02). The median LOS with operational management on HD2 and 3 was 7 and 6 respectively vs median LOS of 2 and 3 with nonoperative management on those days (P-value <.001, .01 respectively). The proportion of patients who failed nonoperative management did not change from baseline until HD4 (23% (95% CI 19.7, 26.3) vs 33.9% (95% CI 28.3, 39.6), P-value <.001).
Discussion: Early mobilization of VATS before hospital day 4 increases the overall hospital cost without offering any length of stay benefit. Continuing nonoperative management longer than 4 days is associated with a high failure rate and a costlier operation.
