Prevalence and characteristics of cluster B personality disorder in a consultation–liaison psychiatry practice

Abstract

Objective. Quantitative studies on cluster B-personality disorder (PD) in the general hospital are scarce. The aim of this study is to examine the prevalence and characteristics of cluster B-PD patients in a consultation-liaison practice. Methods. Files of 258 consecutive patients referred for psychiatric consultation were examined. Cluster B patients were compared with the remaining patients. Results. Eleven point six percent of these patients were diagnosed with a cluster B-PD. On univariate analysis, cluster B patients were more likely to be younger (P < 0.001), unmarried (P = 0.005), and without organic medical illness (P < 0.001).These patients had a shorter admission (P < 0.0001), and were more frequently treated in the emergency room (66.6% versus 37.5%, P = 0.02).There was a trend toward comorbid substance use disorder (P = 0.09). On multivariate analysis, cluster B patients presented significantly with self-harming behavior/ideation (80% versus 18%, OR = 12.07; 95% CI = 4.37–33.31; P < 0.0001). Conclusions. In view of the high prevalence of cluster B-PD in our preliminary study, general hospital staff requires practical skills for managing these high-maintenance patients. We believe that this study and further research will promote evidence-based recommendations for consultation-liaison psychiatrists.
