Concept: Personality Disorders - Measuring Prevalence

Introduction

This concept defines personality disorders and describes how this medical condition has been defined in MCHP research. This includes a list of databases where this information resides, the ICD diagnosis codes that are used to define it, and a list of MCHP research that has investigated personality disorders, with links to the research results and findings in this research.

Personality disorders are a class of mental illnesses characterized by chronic behavioral and relationship patterns that often cause serious personal and social difficulties, as well as a general impairment of functioning (Doupe et al.; 2008).

Technical Definition of Personality Disorders

The technical definition of personality disorders using administrative data includes:

• Data Sources:
  
  • Hospital Abstracts data; and
    
  • Medical Services (Physician Claims) data.
  
  
• Code Values and Conditions: - defined as Manitoba residents with:
  
  
  • one or more hospitalization with a diagnosis for personality disorders:
    
    
    • ICD-9-CM code: 301; OR
      
    • ICD-10-CA codes: F21, F34.0, F60, F61, F62, F68.1, F68.8 or F69; OR
    
    
  • one or more physician visits with a diagnosis for personality disorders using ICD-9-CM code 301.
  
  NOTE: In most MCHP research, the definition is generally restricted to those aged 10 and older. In Chartier et al. (2015), the definition is restricted to those aged 18 and older.

MCHP Research Investigating Personality Disorders

The following sections describe how personality disorders are investigated in several MCHP deliverables and provides links to specific information in each report.

1. Martens et al. (2004)

In the Patterns of Regional Mental Illness Disorder Diagnoses and Service Use in Manitoba: A Population-Based Study deliverable by Martens et al. (2004) they investigated the treatment prevalence of personality disorders separately and as one of five cumulative disorders. For more information, see:


• 2.2 Treatment Prevalence of Cumulative Disorders - information is presented by RHA for 1997/98 to 2001/02; and
  
• 2.9 Treatment Prevalence of Personality Disorders - information is presented by RHA, RHA District, age and sex, and income quintile for 1997/98 to 2001/02

NOTE 1: Additional information on personality disorders is provided throughout the report.
NOTE 2: In addition to using the Hospital Abstracts and Medical Services data, this report also used the Mental Health Management Information System (MHMIS) data.

2. Doupe et al. (2008)

In the An Initial Analysis of Emergency Departments and Urgent Care in Winnipeg deliverable by Doupe et al. (2008) they investigated the use of emergency departments and Urgent Care by patients with mental illness diagnoses, including personality disorders. For more information, see:


• Table 8.4: Distribution of Emergency Department Users by Previous Diagnosis of Select Mental Illnesses
  
• Table 8.5: Distribution of Emergency Department Visits at HSC and SBGH by Mental Illness Diagnosed at the Time of the Visit
  
• Table 9.3: Distribution of Urgent Care Users by Previous Diagnosis of Select Mental Diseases

3. Fransoo et al. (2009)

In the Manitoba RHA Indicators Atlas 2009 deliverable by Fransoo et al. (2009) they compared the prevalence of personality disorders between 1996/97-2000/01 and 2001/02-2005/06 separately and as one of five cumulative disorders. For more information, see:


• Table 5.1: Comparison of Mental Illness Prevalence Values
  
• Section 5.1 - Cumulative Mental Illness that contains information on cumulative mental illness prevalence by RHA; and
  
• Section 5.6 - Personality Disorders that contains information on personality disorders prevalence by RHA, RHA District and Winnipeg Neighbourhood Clusters

4. Martens et al. (2010)

In the Profile of Metis Health Status and Healthcare Utilization in Manitoba: A Population-Based Study deliverable by Martens et al. (2010) they compared a cohort of Metis to all other Manitobans on several aspects of health. They investigated and compared the prevalence of personality disorders as one of five conditions in a cumulative mental illness condition, separately, and as a comorbidity of mental illness diagnoses. The general time frame for this study is from 2002/03 to 2006/07. For more information, see:


• Section 4.10 - All Cause Five-Year Mortality Rates for Individuals with Cumulative Mental Illness including information by RHA, Metis Region, and Winnipeg Community Area;
  
• Table 6.0 - Overall Key Findings of Mental Illness Indicators
  
• Section 6.1 - Cumulative Mental Illness that contains prevalence information by RHA, Metis Region and Winnipeg Community Area.
  
• Section 6.6 - Personality Disorders that contains prevalence information by RHA, Metis Region and Winnipeg Community Area.
  
• Section 6.8 - Comorbidity of Mental Illness Diagnoses that includes information on comorbidities among specified mental illness disorders for the Metis population and all other Manitobans.

5. Martens et al. (2010)

In the Health Inequities in Manitoba: Is the Socioeconomic Gap in Health Widening or Narrowing Over Time? deliverable by Martens et al. (2010) they investigated personality disorders as one of five conditions belonging to a condition termed "cumulative mental health illness". The time frame for this study covered 1984/85 to 2008/09 and includes five different 5-year periods. For more information, see:

• Chapter 7 - Mental Health - Cumulative Health measuring five-year periods of prevalence over time, including information by RHA, income quintiles, rural and urban areas, and using Lorenz curves

6. Chartier et al. (2012)

In the Health and Healthcare Utilization of Francophones in Manitoba deliverable by Chartier et al. (2012) they compared the prevalence of personality disorders between a Francophone cohort and a group of Other Manitobans for 2004/05 - 2008/09, separately and as one of five cumulative mental health disorders. Rate ratios are used to compare the two groups. For more information, see:


• section 6.1 Cumulative Mental Health Disorders
  
• section 6.5 Personality Disorders

7. Chartier et al. (2015)

In Care of Manitobans Living with Chronic Kidney Disease deliverable by Chartier et al. (2015) they investigated the prevalence and relative risk of personality disorders as part of a term called "any mental disorder" in cohorts of patients with end stage kidney disease (ESKD), chronic kidney disease (CKD), and no CKD. Analysis was restricted to those aged 18 years and older. For more information, see:


• Table 4.2: Mental Disorders in Adults in End Stage Kidney Disease Patient Cohorts
  
• Table 4.6: Mental Disorders in Adults in Chronic Kidney Disease Patient Cohorts

8. Chartier et al. (2018)

In this reseach, the findings are illustrated and discussed by Health Region, Health Region District, Winnipeg Neighbourhood Cluster, Age and Sex, and Income Quintile. For more information, see the section titled Personality Disorders in the online deliverable.
