AbstractPURPOSE OF THE STUDY The study aims to quantify the costs of a hospital stay of patients with total knee periprosthetic joint infection throughout the period of treatment. MATERIAL AND METHODS The group included patients who have been treated at our department for infection as a complication of total knee replacement since 1 January 2011, who have been provided with treatment (including complications) exclusively at the departments of Nemocnice České Budějovice, a.s. and whose treatment can be considered completed in 2018. The patients were included in the study regardless of the type of infection and method of treatment. The group consisted of 24 patients (11 men and 13 women). There were 2 cases of early postoperative infection, 6 cases of late postoperative infection and 16 cases of hematogenous infection. The group includes 17 patients treated by a two-stage reimplantation, 6 patients treated by a revision surgery with implant retention, and 1 patient treated by a one-stage replacement. In selected patients, all the reported points for all the hospital stays and costs incurred on a separately charged material were ascertained and the final sum was compared with the reimbursement obtained by the hospital in the DRG system valid for the respective year of treatment. The total costs were analysed and moreover, an analysis by type of infection and method of treatment was carried out. RESULTS The average costs of managing infection as a complication of TKA in our department amounted to CZK 405 864 (CZK 66 768-CZK 181 17). The average cost of a two-stage revision was CZK 497 487, the cost of a revision surgery with original implant retention was CZK 175 312. The reimbursement in respect of the monitored cases in the DRG system equalled CZK 276 230 (CZK 40 943-CZK 848 401). The aforementioned suggests that the average loss per a treated patient is CZK 129 635 (CZK + 26 066Kč-CZK -332 774). DISCUSION Our study is in agreement with recent literature, when confirming that the care associated with infections as a complication of TKA is very costly (especially in case of a two-stage reimplantation) and also that this care is not fully covered by the health insurance company. The reimbursement made by the health insurance companies does not cover on average 1/3 of the costs of care for an infectious patient. Theoretically, the reasons behind the reduced reimbursement may be sanctions which, however, cannot be accepted in case of late hematogenous infections which constituted more than 50% in our group. CONCLUSIONS Our study presented the actual costs associated with the care of TKA infection. It makes sense that the most expensive is the two-stage reimplantation, which is nevertheless still considered to be the gold standard procedure in chronic TKA infection. High costs of therapy together with the requirement of expert care would justify the introduction of care provided by specialised centres. In this case, centralisation could result in a more efficient use of funds and improvement of the quality of provided care.
