 Investigators further adjust search costs for variation in practices during searches. At times surgeons continue with the procedure e.g. closing the wound while in other cases surgeons will assist with efforts to locate the sponge. As investigators are interested in time spent on non-productive searches, investigators will use a range of estimates of non-productive search costs. Investigators start with 100 non-productive and also estimate based on 75 non-productive 25 of the search time moving forward with the procedure and 50 non-productive 50 of the search time moving forward with the procedure. Investigators will use the average radiography costs from published literature 286 in addition to the operating room time associated with obtaining an intraoperative radiograph 30minutes. All times and costs will be analyzed using ranges, means, and standard deviations. Comparison before and after implementation of the RF detection technology will be described as percentages and analyzed using chi square with Yates correction.
