Amid the coronavirus disease 2019 (COVID-19) pandemic, healthcare workers (HCW) have been overworked and faced with the risk of being infected with severe acute respiratory syndrome coronavirus (SARS-CoV-2), the causative pathogen of COVID-19.
A new study by US-based researchers – at the Northwest Mental Illness Research, Education and Clinical Center and Columbia University – has found that healthcare workers have experienced significant psychiatric distress during the pandemic.
The coronavirus pandemic
The coronavirus pandemic first emerged in Wuhan City, China, in December 2019. Since then, it has spread to 191 countries and territories, infecting over 76.79 million and killing more than 1.69 million people.
Due to the scale and speed of the virus’s spread, many countries’ healthcare systems were overwhelmed, and hospitals faced a shortage of intensive care unit (ICU) beds, personal protective equipment (PPE), and personnel.
The impact of the prolonged physical and emotional stress on HCW and first responders (FR) working during the pandemic has attracted significant attention in the media. Previous studies have also tackled the physical and emotional stressors among these workers, linked with significant personal distress and decreased professional longevity.
Previous studies have tied the pandemic to higher psychiatric symptoms among healthcare workers, including depression, insomnia, anxiety, and post-traumatic stress disorder (PTSD).
A study in New York found increased use of medical leave, leading to decreased workforce availability among healthcare workers.
Significant psychiatric distress
The study, which appeared on the preprint medRxiv* server, aimed to determine the relationship between COVID-19 stressor frequency and psychiatric rating scale scores among HCW/FR. The team also wanted to determine if the psychiatric rating scale scores affect the perceived work function and work longevity.
To arrive at the study findings, the team assessed the rate of depression, insomnia, anxiety, and PTSD symptoms in both traditionally defined HCW, as well as in FR, such as police officers, firefighters, and EMTs working during the pandemic.
The study involved 118 HCWs and FR caring for COVID-19 patients in the United States. The team used the PTSD checklist (PCL5), the Patient Health Questionnaire (PHQ9) for depression, the Insomnia Severity Index (ISI), and the General Anxiety Disorder 7 (GAD7).
The team has found that 31% of the 104 participants who completed the COVID-19 occupational exposure assessment had been ill with known or likely COVID-19. Another 19% reported a close family member who had been ill with known or likely COVID-19, and 12% reported the death of a family member due to COVID-19. About 30% also said that they had underlying health conditions that placed them at an increased risk of COVID-19.
The team revealed that 26% of the participants had a total PCL5 score of 31 or higher, indicating PTSD symptoms. These are symptoms that are usually experienced after traumatic stress. In terms of depressive symptoms, 60% of the participants had a total PHQ9 score that is above the standard threshold for mild depression, and 28% had an ISI score for least moderate insomnia. Lastly, 67% had a GAD7 score for mild anxiety.
