Many bladder pain syndrome/interstitial cystitis (BPS/IC) patients report multiple pain locations outside the pelvis. No research has examined pain using a whole-body diagram, pain-associated adjustment factors, or the impact of pain in multiple body areas on patients’ quality of life (QoL).
Compare and contrast pain in BPS/IC patients and controls using a whole-body diagram (visible body areas). Examine the association between patient adjustment factors and greater number of body pain areas (pain phenotypes).
Design, setting, and participants
Validated questionnaires were collected from diagnosed, tertiary-care, outpatient, female BPS/IC patients (n
Outcome measurements and statistical analysis
Cross-tabulation and analysis of variance models addressed the patient and control differences.
Results and limitations
Patients reported more pain than controls in all reported body areas. Four pain phenotypes were created based on increasing counts of body locations (BPS/IC only, BPS/IC
Patients reported numerous systemic pain symptoms outside the areas associated with the bladder/pelvic region, and increased numbers of body pain sites were associated with poorer patient outcomes (ie, pain severity, depression). This study illustrates the significant negative impact of pain on patient adjustment in BPS/IC. These findings suggest that clinicians carefully consider pain location distributions and the potential impact of body pain phenotypes during patient evaluation and treatment planning.
