Abstract

BACKGROUND:

Cluster B personality disorders (PDs) are prevalent mental health conditions in the general population (1%-6% depending on the subtype and study). Affected patients are known to be heavier users of both mental and medical health care systems than patients with other clinical conditions such as depression.

METHODS:

Several rates were estimated using data from the integrated monitoring system for chronic diseases in the province of Quebec, Canada. It provides a profile of annual and period prevalence rates, mortality rates, and years of lost life as well as health care utilisation rates for Quebec residents. All Quebec residents are covered by a universal publicly managed care health plan. It is estimated that the monitoring system includes 99% of Quebec's 8 million inhabitants.

RESULTS:

Quebec residents aged 14 years and older were included in the study. The lifetime prevalence of cluster B PDs was 2.6%. The mean years of lost life expectancy were 13 for men and 9 for women compared to the provincial population. The 3 most important causes of death are suicide (20.4%), cardiovascular diseases (19.1%), and cancers (18.6%). In 2011 to 2012, 78% had consulted a general practitioner and 62% a psychiatrist, 44% were admitted to an emergency department, and 22% were hospitalised.

CONCLUSIONS:

Considering mortality, cluster B personality disorder is a severe condition, is highly prevalent in the population, and is associated with heavy health care services utilisation, especially in emergency settings.
