5 Steps to Improve QoC….and change clinical practice

1. Re-look at concept / criteria /symptoms

2. Understand Detection Problems

3. Understand special populations

4. Consider Enhanced Detection

5. Tie Detection to Clear Action

4. Comorbid Depression

Back to Basics

Page 58: RCPsych AGM10 - Diagnosing depression in primary care and hospital settings new evidence (v3)

Approaches to Somatic Symptoms of DepressionInclusiveUses all of the symptoms of depression, regardless of whether they may or may not be secondary to a physical illness. This approach is used in the Schedule for Affective Disorders and Schizophrenia (SADS) and the Research Diagnostic Criteria.

ExclusiveEliminates somatic symptoms but without substitution. There is concern that this might lower sensitivity. with an increased likelihood of missed cases (false negatives)‏

EtiologicAssesses the origin of each symptom and only counts a symptom ofdepression if it is clearly not the result of the physical illness. This is proposed by the Structured Clinical Interview for DSM and Diagnostic Interview Schedule (DIS), as well as the DSM-III-R/IV).

SubstitutiveAssumes somatic symptoms are a contaminant and replaces these additional cognitive symptoms. However it is not clear what specific symptoms should be substituted
