A systematic review of validated suicide outcome classification in observational studies

BACKGROUND: Suicidal outcomes, including ideation, attempt, and completed suicide, are an important drug safety issue, though few epidemiological studies address the accuracy of suicidal outcome ascertainment. Our primary objective was to evaluate validated methods for suicidal outcome classification in electronic health care database studies. METHODS: We performed a systematic review of PubMed and EMBASE to […]

National Suicide Rates a Century After Durkheim: do we Know Enough to Estimate Error?

Durkheim’s nineteenth-century analysis of national suicide rates dismissed prior concerns about mortality data fidelity. Over the intervening century, evidence documenting various types of error in suicide data has only mounted & surprising levels of such error continue to be routinely uncovered. Yet the annual suicide rate remains the most widely used population-level suicide metric troday. […]

Suicidal Behavior: the Need for its Documentation in Multiaxial DSM-V Diagnoses


Can Novel Nosological Strategies aid in the Identification of Risk for Suicidal Behavior?

In this editorial, the authors discuss the way suicidal behaviour is currently classified in the DSM-IV – only as a symptom in the context of Major Depressive Episode or of Borderline Personality Disorder. They recommend that suicidal behaviour be considered a separate diagnostic category & documented on a sixth axis. (16 refs.)

Issues for DSM-V: Suicidal Behavior as a Separate Diagnosis on a Separate Axis

Severity of Depressive Episodes According to ICD-10: Prediction of Risk of Relapse and Suicide

All psychiatric inpatients in Denmark who had received a diagnosis of a single depressive episode at their first discharge between 1994-1999 were identified. The risk of relapse & the risk of suicide were compared for patients discharged with an ICD-10 diagnosis of a single mild (1103 patients), moderate (3182 patients) or severe (2914 patients) depressive […]

Mild Disorders Should not be Eliminated From the DSM-V

High prevalence estimates in epidemiological surveys have led to concerns that the DSM system is overly inclusive & that mild cases should be excluded from future DSM editions. This article demonstrates that DSM-III-R disorders can be placed on a severity gradient that has a dose-response relationship with outcomes assessed a decade later, & that no […]

An Evaluation of External Cause-of-Injury Codes Using Hospital Records From the Indian Health Service, 1985

This study examined external cause-of-injury & poisoning codes from American Indian Health Service hospital records in order to evaluate the usefulness of International Classification of Diseases coding. Of the 10,921 hospital discharge records with at least one injury-related diagnosis or health service code, 7.3% were coded as suicide/attempt. The authors conclude that this coding was […]

Surveillance of Poisoning and Drug Overdose Through Hospital Discharge Coding, Poison Control Center Reporting, and the Drug Abuse Warning Network

The authors compared 4 measures of poisoning incidence by studying a case series at 2 urban hospitals. In multiple logistic regression, factors of age, hospital admission, suicidal intent, principal poisoning or overdose type, & mixed drug overdose were statistically significnat predictors of case match or report varying by surveillance measure. Findings indicate that common surveillance […]

The Validity of Major Depression With Psychotic Features Based on a Community Study

This article reports on the evidence for the validity of psychotic major depression as a distinct subtype based on cross sectional and 1 year prospective data from the Epidemiologic Catchment Area study.
