Q: Patient Health Questionnaire-nine (PHQ-9) is a scoring system to determine severity for?

A) Depression 
B) Anxiety 
C) Pain
D) Sedation 
E) Delirium 

Answer: A

PHQ-9 is a questionnaire to determine the severity of depression. If a patient scores more than 20, it determines severe depression and may warrants ICU admission, particularly if reported with suicidal ideation.

It consists of nine questions, and each question can have a maximum of 3 points, ranging from 0 to 3, depending on severity reported by a patient - not determined by a provider.

The score was developed by Drs. Robert L Spitzer, Janet BW Williams, Kurt Kroenke, and colleagues, with an educational grant from Pfizer, Inc. It has no copyrights and no permission is required to reproduce, translate, display or distribute.
