Background: Necrotising fasciitis is a serious bacterial infection of the soft tissue and fascial layers beneath the skin which can spread rapidly, with potentially life-threatening consequences. The aim of this study was to audit presentations of necrotising fasciitis under orthopaedic services in the Bay of Plenty region over a 2-year period. Methods: All cases of necrotising fasciitis diagnosed in Tauranga and Whakatāne hospitals from 1 April 2021 to 31 March 2023 were identified and obtained using ICD-10 coding data. Descriptive analysis was used to report incidence rates. The literature was searched to identify global trends in necrotising fasciitis and explanations for trends were explored. Results: Five cases of necrotising fasciitis were identified over the study period. All cases were diagnosed during the final 5 months of the study period. Many body sites were implicated, with some cases of multifocal infection. Implicated sites included the foot and ankle (n=3), upper arm (n=2), lower leg (n=2), pelvis and thigh (n=l), and forearm (n=1). There was no clear association between age, gender, ethnicity, and location of inhabitancy with rates of necrotising fasciitis. Conclusion: Necrotising fasciitis is an orthopaedic emergency. Our results showed a sharp increase in its incidence under orthopaedic services in the Bay of Plenty region, which is consistent with wider literature and a cause for concern.. Increasing awareness, bacterial virulence, and increasing prevalence of comorbid conditions have been speculated as possible drivers of necrotising fasciitis rates. Further research is warranted to identify causes and prevention strategies for necrotising fasciitis.
