Prevalence and Severity of Depression Among Cardiothoracic Surgery Healthcare Workers in Baghdad: A PHQ-9 Cross-Sectional Study

Assessing the Prevalence and Severity of Depression Among Cardiothoracic Surgery Healthcare Workers in Baghdad Using the PHQ-9: A Cross-Sectional Study

This observational study aims to estimate the prevalence and severity of depression in HCWs in cardiothoracic surgery departments in Baghdad City, Iraq, using a self-administered PHQ-9 questionnaire. The main questions it aims to answer are:

What is the prevalence of depression among cardiothoracic surgery healthcare workers? How is the severity of depression distributed within this group? Are there specific occupational or demographic factors associated with higher levels of depression?

Participants will:

Fill out the PHQ-9 in order to measure the severity of depressive symptoms at a specific moment in time.

Demographic and occupational details such as age, gender, years of experience and position held should be taken to look for possible relationship with depression.

Major depressive disorder is a prevalent, severe, and recurring mental health condition.There is a significant difference in the prevalence of major depressive disorder across various socioeconomic contexts and countries. Depression is a debilitating mental illness, severely impacting psychosocial function and quality of life.

Individuals, including healthcare workers, are at risk of developing various psychological disorders, with depression being the most prevalent. In Iraq, healthcare workers are particularly vulnerable to psychological distress due to the nature of their job. They often have to deal with heavy workloads, night shifts, and shift work, which can take a toll on their mental well-being. These occupational stress factors can lead to burnout, anxiety, sleep problems, psychiatric disorders, or even depression. It has been reported that the screening for depression among healthcare workers is on the rise. Healthcare workers and individuals who work in the healthcare industry often experience symptoms of anxiety and depression at a significant rate.

There are several tools that can be used to screen for depressive disorders. One commonly used instrument in primary care is the Patient Health Questionnaire-9 (PHQ-9), which is a brief, self-administered, and easy-to-score tool that is well-validated for detecting and monitoring changes in depression severity. and detection of this condition in large epidemiological studies As this instrument is based on DSM-IV criteria, it tends to identify cases with Major Depressive Episode (MDE) when the scores are high. Additionally, it can be utilized to evaluate the intensity of depression by distinguishing between mild to severe cases. However, it is important to note that there is mounting evidence that the cut-off points used to determine the degree of severity may differ based on various contexts.

This study addresses the mental health gap among Iraqi healthcare workers, particularly in cardiothoracic surgery, within a healthcare system strained by war, resource shortages, and heavy patient loads. Despite these challenges, few studies assess depression in this group. Findings aim to inform mental health support policies for high-stress medical fields in Iraq.
