Comparison of Australian and New Zealand referral rates for hyperbaric oxygen in oro-facial osteoradionecrosis: evidence-based, funding constraint or clinician whim?

What Researchers Did

Researchers compared the rates of referral to hyperbaric units for oro-facial osteoradionecrosis patients in Australia and New Zealand by collating and analyzing patient treatment data from all hyperbaric units in both countries.

What They Found

The referral rate to hyperbaric units for oro-facial osteoradionecrosis in Australia was 1.7 times higher than in New Zealand. Additionally, a greater than three-fold variation in referral rates was observed within Australia across different states.

What This Means for Canadian Patients

While this study focused on Australia and New Zealand, its findings suggest that similar variations in referral rates for hyperbaric oxygen therapy might exist within Canada. This highlights the importance of standardized guidelines and equitable access to specialized treatments for Canadian patients at risk of oro-facial osteoradionecrosis.

Canadian Relevance

This study has no direct Canadian connection as it focused exclusively on referral rates within Australia and New Zealand.

Study Limitations

The study did not definitively determine the underlying causes for the observed referral rate variations, only suggesting possible factors like funding access or clinician preference.
