Psychiatry & Psychosomatic Medicine

Statement of the Problem: There are a specific sub-group of patients with emotionally unstable personality disorder (EUPD) who tend to somatize overwhelming feelings rather than act them out via risky behaviors. They present to primary care services, receive polypharmacy and are more likely to commit suicide. There are neuropsychiatric, psychodynamic and developmental explanations for their tendency to somatize, but very little epidemiological data. We performed an audit of a tier-3 personality disorder unit to determine the prevalence of psychosomatic disorders in this population and to determine any relationship between these diagnoses, prescribing practices and attendance at therapy.

Methodology & Theoretical Orientation: We conducted an audit of 63 waiting-list patients and performed a key-term search to determine frequency of psychosomatic symptoms. We also performed a sub-group analysis of those patients in mentalization-based therapy (i.e., with confirmed EUPD) and recorded the medications they were prescribed and their attendance at therapy.

Findings: Psychosomatic conditions affected 57% of the waiting list population and 77% of the sub-group analysis. The most common complaints were unexplained musculo-skeletal pain, unexplained chest pain and irritable bowel syndrome. Those with co-morbid psychosomatic conditions were prescribed more medications, missed more therapy and cited medical reasons more often for missed appointments.

Conclusion & Significance: Psychosomatic disorders are more common in patients with EUPD than those without the diagnosis. Psychosomatic disorders impact on attendance at therapy and increase the risk of polypharmacy. As such, psychosomatic conditions should be routinely screened for at assessment and be positively diagnosed so that they can be addressed as a barrier to engaging in treatment and understood within therapy as a coping mechanism. Psychosomatic disorders should be among the list of differentials as the multi-disciplinary team investigate, interpret and manage physical symptoms sensibly.
