A Cost Benefit Between Pyxis And Bar Coding For The Brooke Army Medical Center Operating Room PDF Download

Brooke Army Medical Center (BAMC) is analyzing methods to optimize the operating room (OR). One goal of BAMC's OR is to capture supply costs associated with different procedures as well as to assign the costs to patients. Another goal is to provide real time access to supplies for patient care for a variety of elective and non-elective surgeries in a tertiary care medical center with a level I trauma mission. A cost effective analysis was conducted to compare Pyxis, a secure cabinet that uses touch-to-take technology, to bar coding technology. The study was conducted in two phases. The first phase used the Army decision making tool, DECMAT, to decide which system best accomplished the goals of the study. Pyxis with a value of 3.751 was chosen over bar coding, 1.000E9. The second phase of the study measured how accurately the selected system, Pyxis, calculated the costs of the supplies used for designated procedures versus using physician preference cards, prime vendor pricing lists, credit card purchases, and contracts to manually calculate the costs of supplies. The statistical software package, Statistical Package for Social Sciences (SPSS) 12.0.1, was utilized to determine the variance for the dependent variable, current procedural terminology codes (CPT) codes, and the two independent variables, manual and Pyxis calculation of costs. Descriptive statistics were utilized to determine the mean and standard deviation for the manual calculations as $2,726.61 and $2,573.84; and $2,799.33 and $2,646.08 for Pyxis. An Independent T-test and ANOVA table was used to determine the statistical significance of the variation. The F-test value, .015 and .003, for both tests illustrated little scientific significance between the two independent variables.
