What Researchers Did
Researchers in France conducted a retrospective survey to count occupational accidents among staff working in hyperbaric chambers from 2005 to 2011.
What They Found
Out of 73 staff members from 12 participating centres, 27% reported at least one accident. A total of 30 accidents occurred, with 20 being hyperbaric-related, primarily ear traumas (70%), followed by decompression illness (15%) and cutaneous decompression sickness (10%). The overall accident rate was 372 per 100,000 hyperbaric sessions, with hyperbaric-specific accidents at 248 per 100,000 sessions.
What This Means for Canadian Patients
This study highlights the importance of safety protocols for staff operating hyperbaric chambers, which indirectly ensures a safer environment for patients receiving HBOT. Understanding common staff accidents, like ear traumas, can help Canadian hyperbaric facilities implement better training and preventative measures to protect their teams and maintain high standards of care.
Canadian Relevance
This study is not Canadian. However, it covers decompression sickness, which is a Health Canada-recognised indication for hyperbaric oxygen therapy.
Study Limitations
The study's retrospective design and reliance on self-reported questionnaire data from less than half of the hyperbaric centres in France may have led to underreporting or recall bias.
