Prevention of retained surgical sponges: a decision-analytic model predicting relative cost-effectiveness.
Regenbogen SE, Greenberg CC, Resch SC, et al. Prevention of retained surgical sponges: a decision-analytic model predicting relative cost-effectiveness. Surgery. 2009;145(5):527-35. doi:10.1016/j.surg.2009.01.011.
A cost-effectiveness analysis model was used to assess the utility of three methods for preventing retained surgical sponges: bar-coded sponges, radiofrequency ID–tagged sponges, and standard x-ray screening. The newer technologies were found to be more cost effective.
