Abstract. Aim: This study aimed to define the costs of surgical management of chronic osteomyelitis where free tissue transfer was required in addition to debridement of bone, particularly the increased costs incurred by a return to theatre. We hypothesised that there would be a significantly greater cost when patients required re-exploration for vascular compromise.

Method: We retrospectively analysed the costs of a consecutive series of sixty patient episodes treated at the Bone Infection Unit in Oxford from 2012 to 2015. Treatment involved excision of osteomyelitis with free tissue transfer for immediate soft tissue cover. We compared the costs of uncomplicated cases with those who returned to theatre and determined the profit / loss for the hospital from renumeration through the UK National Health Service Tariff Structure.

Results: Hospital income according to UK HRG tariff was compared to the actual cost of treatment and these 60 cases were significantly underfunded overall (P < 0.005). In just 1 case, the cost to the hospital was completely covered by tariff.

Six patients (10%) returned to theatre for urgent flap re-exploration with five flaps salvaged and one failed, requiring another free flap reconstruction (1.7%). These six patient episodes had a significantly higher mean cost compared to the uncomplicated cases. The average financial loss to the hospital for patients who did return to theatre was £19401 (range £8103 to £48380) and in those who did not was £9600 (range - £600 to £23717). The case requiring further free tissue transfer cost a total of £74158, £48380 more than the hospital was paid: the most extreme discrepancy. The overall loss for this group of 60 patients was £610 090.

Conclusions: Surgery for chronic osteomyelitis is multidisciplinary, complex and therefore expensive with a significant risk of complications. However, this study demonstrates that the hospital currently makes a financial loss on almost all patients but especially if flap complications occur. This study has implications for the long term viability of specialist units treating this important disease.
