Abstract
Chronic osteomyelitis is a challenging problem and a growing burden for the National Health Service. Conventional method of treatment is 2 stage surgery, with debridement and prolonged courses of antibiotics. Recently single stage treatment of chronic osteomyelitis is gaining popularity due decreased patient morbidity and cost effectiveness. Dead space management in single stage treatment is accomplished by either a muscle / myocutaneous or antibiotic loaded calcium sulphate beads.
We analysed the cost effectiveness of two dead space management strategies in single stage treatment of osteomyelitis. Study is designed to analyse the health economics at 2 time points; 45 days post surgery and 2 years post surgery. We report preliminary results at 45 days post surgery.
Setting – Level 1 trauma centre and university hospital
Approval – Ethics committee approved study
10 patients in each group were retrospectively analysed through patient records. Each group was identified for standard demographics, duration of procedure, hospital stay, type and duration of postoperative antibiotics, number of out patient visits in first 45 days and recurrence of infection.
Table attached details the results of both groups
In health technology assessment four quadrant model, CSB appears in quadrant II suggesting that it is more cost effective.
Based on small data set and on assessment only evaluating cost, at 45 days assessment, antibiotic calcium sulphate beads from a Health Economic Cost Effectiveness Analysis offers a better economic outcome. This is holding constant the morbidity of the patients and effectiveness, assuming both treatments are standards of care, which is best evaluated at 24 months.
