To describe a chronic pelvic pain population and assess for centralized pain using a validated fibromyalgia scale, and further to evaluate how the fibromyalgia phenotype correlates with patient clinical characteristics.METHODS:
A retrospective chart review was performed of new patients who presented to the University of Michigan Chronic Pelvic Pain Clinic in the department of Obstetrics and Gynecology from January to November 2013. We collected patient demographics, pain characteristics and treatments, medical history, fibromyalgia survey score, Brief Pain Inventory (BPI), and standardized depression, anxiety and sleep surveys. Fibromyalgia survey scores were categorized into low (0–4), medium (5–7), and high (8–16) based on previous data and descriptive statistics were applied.RESULTS:
During the study period 312 women presented to the Chronic Pelvic Pain clinic. The majority were White and employed, and the mean age was 35.5±11.7 years. Women with higher fibromyalgia survey scores were younger (33.8±10.6, P=.006), had more days of pain per month and missed days of work, higher pain intensity and interference scores, and significantly more pain with a full bladder (P=.01) and bowel movements (P=.001). Furthermore, women with a fibromyalgia phenotype were more likely to have depression, anxiety, and sleep problems.CONCLUSION:
Higher Fibromyalgia survey scores in a chronic pelvic pain population were significantly associated with higher pain severity and pain interference scores. Similar to other chronic pain conditions, the fibromyalgia phenotype among women with chronic pelvic pain is associated with greater pain morbidity.
