Sensitivity analysis
Table 83 shows the results of the sensitivity analysis varying the efficacy of the
comparator group using the 95% CI, costs of a doctor in attendance during treatment,
varying the number of HBOT sessions per patient and the number of chambers in the
facility.
Table 83 Sensitivity analysis – osteoradionecrosis
Sensitivity Analysis Incremental cost per case of osteoradionecrosis avoided
$28,480 – primary case
15.87% of patients in the comparator group with
$66,187
osteoradionecrosis (lower 95% CI)
46.98% of patients in the comparator group with
osteoradionecrosis (upper 95% CI)
Cost of doctor/specialist covered by cost of patient
assessment prior to a course of HBOT treatment
$16,663
$18,438
15 HBOT sessions per patient $14,212
40 HBOT sessions per patient $37,991
Operating costs shared between 2 HBOT units $16,214
Operating costs shared between 4 HBOT units $10,081
Table 83 shows that if the staff requirements of a hyperbaric nurse, technician and
physician are shared among four HBOT chambers in a hyperbaric facility, the
incremental cost per case of osteoradionecrosis avoided is $10,081. The incremental cost
per case of osteoradionecrosis avoided is $66,187, using the lower limit of the 95% CI
for the efficacy of the comparator group, keeping the efficacy of the HBOT group fixed.
Summary
The incremental treatment cost per case of osteoradionecrosis avoided is estimated to be
$28,480, in patients who had an indication for removal of one or more teeth in a segment
of the mandible. Sensitivity analysis suggests a range of $10,081-$66,187 per case of
osteoradionecrosis avoided.
Conclusions
The indicative cost-effective ratios estimated for a small number of indications i.e.
HBOT in diabetic wounds, necrotising soft tissue infections, and osteoradionecrosis, are
summarised in Table 84.

Diabetic Wounds
- Incremental Cost per Amputation Avoided $22,054 (cost saving to $63,100)
Non-Diabetic Wounds
