UPIBill,
Did you get your Rx for oxygen therapy?
Some interesting statistics regarding oxygen therapy from the
US Cluster Headache Survey many of us completed in 2008:
1134 individuals completed the survey (816 male, 318 female). 868 patients had episodic CH while 266 had chronic CH.
OXYGEN THERAPY USAGE 1. 93% were aware of O2 being an acute therapy.
2. 34% had never tried O2
3. Current users: only 287 patients or 25% of the survey population are using oxygen at present
**Males make up 73% of the current users
WHO PRESCRIBED OXYGEN - 44% had to first suggest O2 therapy to their physicians to get it prescribed.
- There was an equal distribution (28% each) of physician type (general practitioner, general neurologist, headache specialist) who initially prescribed O2.
REASONS WHY A PHYSICIAN WOULD NOT PRESCRIBE O2 1. Did not believe it worked 44%
2. Did not know that O2 was used for CH 32%
3. Stated medical literature not convincing enough to prescribe 16%.
INSURANCE ISSUES - Patient or physician had to submit medical literature 44% of the time to get reimbursement for O2.
- Only 64% of insurers covered O2 for CH.
PRESCRIBING PATTERNS1. 50% of those using O2 never received training on proper use of O2 cylinder equipment or mask.
2. 45% had to find a source to buy O2 on their own.
3. On oxygen prescriptions only 45% specified a flow rate, 50% stated CH as diagnosis and 28% indicated a specific mask type.
4. 12% of CH patients had used welders O2 (non-prescription, less expensive) stating economic reasons including having no insurance.
5. Oxygen delivery systems prescribed:
nasal cannula 11% (useless for CH)
standard mask 29% (also useless for CH)
high concentration non-rebreather mask 47%
6. Initial flow rates prescribed
7 lpm 23%,
8-12 lpm 51%
13-15 lpm 18%
>15 lpm. 6% (25 liters/minute is the lowest flow rate that supports hyperventilation and hyperventilating on 100% oxygen results in very rapid and very safe aborts.)
