A survey of fibromyalgia patients, Functioning with Fibro, developed and funded by Pfizer Inc., and conducted in collaboration with the National Fibromyalgia & Chronic Pain Association (NFMCPA) and the American Association of Nurse Practitioners (AANP), evaluated the extent to which their chronic widespread pain affects various aspects of their life.
The survey of 1,228 adults in the U.S. diagnosed with fibromyalgia, including those with severe fibromyalgia pain,* also evaluated how fibromyalgia patients engage their healthcare providers (HCPs) to help them understand and manage their pain.
*Severe FM pain as defined by those who reported experiencing pain levels of seven and above as measured by the pain
Numeric Rating Scale (NRS) (patient reported, 1-10 with 1 being no pain and 10 being excruciating pain)
The Functioning with Fibro survey was conducted between August 9 and August 23, 2013 using an email invitation and an online survey.
Results of any sample are subject to variation. The magnitude of the variation is measurable and is affected by the number of interviews and the level of percentages expressing the results. In this particular survey the chances are 95 in 100 that a survey result does not vary, plus or minus, by more than 2.8 percentage points from the result that would be obtained if interviews had been conducted with all persons in the universe represented by the sample. The margin of error for any subgroups will be slightly higher.
