{Abstract}: <B>BACKGROUND: </B>Many commercial and artisanal devices are utilized for temporary abdominal closure in patients being managed with an open abdomen for abdominal sepsis. The costs of materials required to treat patients with an open abdomen varies drastically. In Costa Rica, due to the lack of accurate information relating to the actual cost to manage a patient entails that the method with the least expensive materials is usually selected.<BR><B>METHODS: </B>A single-center retrospective review of 46 patients diagnosed with abdominal sepsis and successfully treated with an open abdomen and one of the three temporary abdominal closure methods during the year 2018 in a tertiary hospital was evaluated using a gross-cost pricing model developed by the authors. The three temporary abdominal closure methods were a locally manufactured Bogota Bag, and commercial abdominal negative pressure therapy dressing and negative pressure therapy with 0.9% saline solution instillation. The per-unit-costs were hospital day and intensive care day, number of surgical procedures per patient, cost negative pressure therapy kits.<BR><B>RESULTS: </B>Statistically significant cost reduction was observed in the cohort treated with negative pressure therapy with instillation as compared to the other temporary abdominal closure methods. The reduction of hospital length of stay, as well as fewer number of surgeries were the main contributing factors in diminishing costs. On average, the costs to treat a patient utilizing negative pressure therapy with instillation was nearly 50% lower than using the other two temporary abdominal closure methods.<BR><B>CONCLUSIONS: </B>The costs relating to managing abdominal sepsis in the septic open abdomen vary greatly according to the temporary abdominal closure utilized. If the hospital length of stay, intensive care unit length of stay and number of surgeries required are the main parameters used in determining costs, the use of negative pressure therapy with 0.9% saline solution instillation reduces costs by nearly 50% in comparison to conventional negative pressure wound therapy and Bogota Bag. In this instance, the more expensive method at first glance, obtained a considerable cost reduction when compared to therapies that utilize less expensive materials.
