IPDE-SQ personality disorders impact on healthcare and societal costs in fibromyalgia
Fibromyalgia syndrome (FMS) is characterized by multi focal pain, fatigue, non-restorative sleep, subjective cognitive problems, high levels of distress. FMS is a complex entity recognized as an illness by the World Health Organization (WHO) in 1992 and described in the International Classification of Diseases (ICD-10) under code number M79.
FMS diagnosis is clinical and to date there is no cure, only treatment of symptoms and data is also lacking on comorbid personality disorders and fibromyalgia syndrome. Therefore, to assess the prevalence of personality disorder (PD) in FMS patients, a study was conducted. Further, it was also analyzed that whether the presence of comorbid PD in fibromyalgia syndrome worsen the functional impairment and greater healthcare services.
In a randomized, controlled trial, a cross-sectional study was performed with 216 FMS patients. Controlled trial was carried out in three primary healthcare centers situated in the region of Barcelona, Spain. Measurements were done using International Personality Disorder Examination Screening Questionnaire, the fibromyalgia Impact Questionnaire, the client service receipt inventory and a socio-demographic questionnaire.
After analysis, it was observed that most patients had a potential PD according to the IPDE-SQ. The most prevalent PD were the avoidant, obsessive-compulsive. Statistically significant difference was also observed between FMS patients with potential PD vs non-PD. Presence of PD resulted in more healthcare costs.
At the end, it was concluded that the personality disorder were more frequent comorbid conditions in patients with FMS. Evaluated results suggested that the screening of comorbid PD in patients with FMS might be recommendable for the detection of potential frequent attenders to primary and specialized care.
