  • Title: Comparison of Australian and New Zealand referral rates for hyperbaric oxygen in oro-facial osteoradionecrosis: evidence-based, funding constraint or clinician whim?
    Author: Sames C, Gorman DF, Sandiford P, Zhou L.
    Journal: Diving Hyperb Med; 2015 Dec; 45(4):244-6. PubMed ID: 26687312.
    Abstract:
    AIM: To compare Australian and New Zealand (NZ) rates of referral to hyperbaric units for patients with, or at risk of developing mandibular or maxillary osteoradionecrosis (ORN) due to a history of radiotherapy for oro-pharyngeal cancer. METHOD: Relevant patient treatment data from all hyperbaric units in Australia and NZ were collated and analysed. RESULTS: The rate of referral to hyperbaric units in Australia for treatment or prophylaxis of patients with, or at risk of oro-facial ORN, was 1.7 times the rate of referral in NZ. Within Australia, there was a greater than three-fold interstate variation. CONCLUSION: There is a significant referral rate difference both within Australia and between Australia and NZ for hyperbaric oxygen therapy for oro-facial ORN. Possible reasons for this difference include access to funding, logistical difficulties, clinician preference for an alternative treatment and clinician attitudes to hyperbaric oxygen.
