The global prevalence of primary psychodermatologic disorders: a systematic review.

The management of primary psychodermatologic disorders (PPDs) (i.e. psychiatric disorders with dermatologic presentation) is challenging. The scarceness of reported prevalence hinders the development of coordinated interventions to improve healthcare delivery. This review aimed to explore the global prevalence of PPDs. The review was conducted according to the Preferred Reporting Items for Systematic Review and Meta-Analyses statement. Of the 4632 identified publications, 59 were included. Five PPDs were investigated from the included studies: delusional parasitosis (n = 9), skin picking disorder (n = 26), trichotillomania (n = 26), tanning dependence (n = 5) and repetitive nail biting (n = 6). Delusional parasitosis was rare in the general population (prevalence ranging from 0.0002% to 0.03%), with higher rates in psychiatric settings (outpatient = 0.5%; inpatient = 0.1%). Other pathologic or subclinical forms of PPDs had a minimum prevalence of 0.3% (median = 7.0%; mean = 17.0%). The distribution of the prevalence rates was highly skewed, with large differences based on the study setting (e.g. dermatologic settings, psychiatric settings, and general population). The most common condition was pathologic skin picking (prevalence, 1.2%-11.2%) in the general population. Its rates were higher in the psychiatric settings (obsessive-compulsive disorder, 38.5%; Tourette syndrome, 13.0%; body dysmorphic disorder, 26.8%-64.7%). The prevalence of trichotillomania in the general population ranged from 0.6% to 2.9%, while that of pathologic tanning and nail biting could not be ascertained as the studies were mainly in students (range; 12.0%-39.3% and 3.0%-10.1%, respectively). In conclusion, PPDs are common, especially in the dermatologic and psychiatric settings. Further population-based studies are needed to determine more accurate prevalence rates.

Are psychiatric team meetings patient centred? A cross-sectional survey on patient views regarding multi-disciplinary team meetings.

OBJECTIVES: The system of weekly psychiatric ward rounds is being challenged and multi-disciplinary team meetings (MDTMs) involving inpatients have been developed. These aim to improve integration between medical and social services and increase patient involvement in their care. However, such large meetings are potentially threatening to the patient. This survey aimed to examine inpatient experience of MDTMs and identify factors that significantly alter this experience. METHODS: In this cross-sectional survey we assessed patient opinion regarding patient inclusive MDTMs in a psychiatric inpatient unit. A total of 27 participants (response rate 90%) were included. We utilised descriptive statistics and Fisher's exact test for non-parametric data where appropriate. RESULTS: In all, 85% (n=23) of patients identified the consultant psychiatrist as a member that they would like to have present at the MDTM. The ward nurse was identified by 63% (n=17) of patients. In all, 48% (n=13) of patients reported feeling anxious/threatened at the MDTM. In all, 70% (n=19) of patients stated that they would have felt less threatened at the MDTM if there were fewer people in attendance. A significant number of voluntary patients (n=11) felt threatened/anxious at the MDTM compared with involuntary patients (n=2) (χ 2=4.921, df=1, p=0.026). CONCLUSION: The central findings of this study are that patients would prefer fewer people at the MDTM and would feel less threatened/anxious if they participated in selecting those in attendance. These findings suggest that greater patient involvement in preparation for the MDTM could result in a less anxiety filled experience for them.
