    UnlabelledIn 2004, the American Pain Society (APS) issued evidence-based fibromyalgia treatment recommendations. The objective of this claims database analysis is to describe prescription and medical use in patients with newly diagnosed and established fibromyalgia. Privately insured patients with 2+ myalgia/myositis claims (1999 to 2005) were categorized as newly diagnosed or established; this dichotomy involves comparisons between prediagnosis (S1) and postdiagnosis (S2) stages in the newly diagnosed and between newly diagnosed (S2) and established patients (S3). Use of APS guideline medications increased across stages: selective serotonin reuptake inhibitors (SSRIs) (S1, S2, S3: 20.6%, 22.9%, 25.3%), serotonin norepinephrine reuptake inhibitors (SNRIs) (4.5%, 6.4%, 8.9%), pregabalin/gabapentin (5.4%, 7.4%, 8.8%), benzodiazepines (19.0%, 21.1%, 24.2%), non-benzodiazepine sedatives (9.1%, 11.5%, 13.7%) (all P < .0001), and opioids (39.5%, 43.3%, 43.9%; S1 vs S2, P < .0001; S2 vs S3, P = .2835). Use of multiple therapeutic classes also increased across stages: 3+ classes (7.1%, 9.6%, 11.8%) (all P < .0001). Office visits to providers increased, on average, after diagnosis: primary care (70.9%, 78.3%, 76.3%; all P < .0001), chiropractors (28.8%, 51.1%, 53.3%; all P < .0001), rheumatologists (4.2%, 9.9%, 10.5%; S1 vs S2, P < .0001; S2 vs S3, P = .0595), mental health (6.4%, 7.3%, 8.3%; S1 vs S2, P < .0001, S2 vs S3, P = .0003). Average health care costs rose after diagnosis in the newly diagnosed group (S1: $6555 vs S2: $8654, P < .0001).PerspectiveThis paper investigates prescription drug and medical care use with respect to stages of fibromyalgia diagnosis. Established fibromyalgia patients use more medical resources and have higher rates of concomitant medication use than newly diagnosed fibromyalgia patients. Findings can help educate providers regarding optimal drug treatment patterns in this population.
