Patients with psychodermatological problems are numerous, and can be challenging to manage within the constraints of general dermatology clinics. Despite this, psychodermatology services remain limited in the UK and globally. A study in 2012 found that only 6% of departments in the UK had a dedicated psychodermatology service (1). Commissioners may be reluctant to fund such multidisciplinary services, perceiving them to be costly. This case series, along with two other published studies, shows the reverse to be true (2, 3).
METHODSWe aimed to study the direct healthcare costs associated with caring for 4 typical patients with a range of diagnoses in our psychodermatology service. We used nationally-agreed tariffs to estimate the costs of primary and secondary care consultations, investigations and treatments prior to referral, and compared this to the costs incurred within the psychodermatology service ( Table I). At the time that the patients were cared for, our service comprised a consultant dermatologist conducting joint patient assessments with a senior clinical psychologist. Limited in-house psychological therapy was available thereafter if indicated, but we had to refer on to separate local psychiatric services if this was deemed necessary.
RESULTSPatient A presented with episodic hair loss and was eventually diagnosed with trichotillomania. Prior to referral, her care was estimated to have cost £1,209 (€1,347). She was assessed in the psychodermatology service and received a short course of psychological therapy, costing £386 (€430) in total. This led to acceptance of her hairpulling and resulted in resolution of her symptoms.Patient B was referred to dermatology with multiple large bullae and erosions. She also reported a myriad of other complaints including widespread pain, visual loss, headaches, weakness, incontinence, twitching, recurrent abdominal pain and dyspnoea. She had been thoroughly assessed by multiple departments over 5 years. She was eventually diagnosed with factitious skin disease and medically unexplained symptoms. Prior to referral, the cost of investigating and treating her skin complaint was £5,555 (€6,190). A conservative estimate of the cost with regard to her additional symptoms was £14,979 (€16,692). Psychodermatology input, costing £218 (€242), helped her to identify that her predominant problem was with her mental health and she agreed to psychiatric referral. This resulted in marked improvement in both her skin and other symptoms, including regaining of some of her vision, allowing her to be discharged to psychiatric services.Patient C presented with painful, non-healing erosions which he attributed to tick bites. He had amassed an extensive collection of samples and had consulted a number of clinics around the region. He was diagnosed with delusional infestation and was referred to the psychodermatology clinic where he has been started on risperidone. The cost of his care prior to referral was £2,892 (€3,223). Within the psychodermatology service, his care has so far cost £46...
