Objective: getting to know the total cost of each type of bedsore (pressure sores), as it is a chronical injury commonly seen in patients with low mobility. Method: We realized a retrospective review of clinical records for the 2008 to 2011 period, corresponding to the plastic surgery activity records of the Paraplegic Hospital. Results: the ischial pressure sore is the most commonly treated (43.27%), and also shows the lowest total cost (€ 57,196.29). The highest cost of a bedsore due to its location corresponds to sacral pressure sores (40.41%, being the second most frequent type, with a total cost of € 112,012.96). Conclusions: Faced with these treatment costs, prevention campaigns are established in an attempt to prevent these high costs to the National Health System.
