Inclusion criteria

Inclusion criteria: The data collection period spanned from April 1, 2022, to March 31, 2025. Patient records were extracted from the hospital's electronic medical record system. Cases with a documented insurance diagnosis of 'fibromyalgia' were initially identified. To account for potential omissions, additional cases were manually reviewed and identified based on outpatient records maintained by the attending physicians.

Design outcomes

Primary

Measure	Time frame
Pain intensity and distribution were assessed using the Numerical Rating Scale (NRS), Widespread Pain Index (WPI), Symptom Severity Scale (SS), the Short-Form McGill Pain Questionnaire (SF-MPQ), and the Brief Pain Inventory (BPI). These assessments were conducted at the initial visit and at each subsequent outpatient visit. If the initial consultation occurred at another institution, and relevant pain scale data were included in the referral documents, those data were utilized. The baseline values were defined as those recorded at the initial visit, and the final values were defined as those recorded as of March 2025. In cases where no data were available in March 2025, the most recent available data prior to that date were used as the final values. For patients who discontinued follow-up, the last recorded values at the time of discontinuation were considered the final values. The rate of change was calculated based on these baseline and final values.	—

Secondary

Measure	Time frame
For approximately 40 hospitalized patients, changes in pain intensity during hospitalization were evaluated. In patients with comorbid migraine, headache severity was assessed using the Headache Impact Test-6 (HIT-6) and the Migraine Disability Assessment Scale (MIBS-4). In addition, relevant clinical data were collected, including laboratory tests, computed tomography (CT), magnetic resonance imaging (MRI), radionuclide imaging (RI), and electrophysiological studies.	—
