# Prolonged Effects on Frontline Caregivers: Occupational Stress and Mental Well-Being in Transformed Healthcare Environments Post-COVID-19

## TL;DR

This study shows that nursing technicians in Brazil's emergency units face high anxiety and poor quality of life due to stressful work environments and pandemic effects, which impacts their ability to provide quality healthcare.

## Contribution

The study identifies the pandemic's prolonged psychological effects on frontline healthcare workers as a systemic public health issue, emphasizing the need for environment-focused interventions.

## Key findings

- Nursing technicians in Brazilian emergency units experience pervasive anxiety and compromised quality of life due to work stress and pandemic effects.
- Psychological distress is strongly linked to lower quality of life and depression in social relationships.
- Work environment stress, not sociodemographic factors, is the primary driver of mental health issues among these professionals.

## Abstract

Public health relevance—How does this work relate to a public health issue?
This study investigates the mental health and quality of life among nursing technicians working in Brazilian Unified Health System (SUS) emergency units, a critical workforce for public health, particularly in the post-COVID-19 pandemic context.The research demonstrates that the inherently stressful work environment and the psychosocial sequelae of the pandemic contribute to pervasive anxiety and compromise the quality of life and social relationships of these professionals, thereby directly impacting their capacity to deliver high-quality healthcare to the population.

This study investigates the mental health and quality of life among nursing technicians working in Brazilian Unified Health System (SUS) emergency units, a critical workforce for public health, particularly in the post-COVID-19 pandemic context.

The research demonstrates that the inherently stressful work environment and the psychosocial sequelae of the pandemic contribute to pervasive anxiety and compromise the quality of life and social relationships of these professionals, thereby directly impacting their capacity to deliver high-quality healthcare to the population.

Public health significance—Why is this work of significance to public health?
The study reveals that the intrinsic and demanding nature of emergency work, exacerbated by the prolonged effects of the pandemic, represents the primary stressor for nursing technicians, superseding sociodemographic and professional factors such as salary or workload. This indicates a systemic public health issue requiring environment-centric approaches.The identified widespread anxiety, characterized as a common and persistent experience among these professionals, suggests a “chronic allostatic load” or a “Long COVID-19” effect on the mental health of frontline workers. This condition can precipitate compassion fatigue and care errors, ultimately jeopardizing patient safety and the effectiveness of SUS emergency services.

Public health implications—What are the key implications or messages for practitioners, policy makers and/or researchers in public health?
For policymakers and healthcare administrators, support interventions must extend beyond traditional solutions (e.g., salary adjustments or workload modifications), emphasizing the adaptation of work environments to the “new realities” of the post-pandemic era, fostering communication, and combating isolation.It is imperative to develop comprehensive strategies that enhance the overall quality of life and coping mechanisms of nursing technicians through robust organizational and individual support. This approach aims to mitigate amplified psychological impacts and ensure the sustained quality and safety of patient care in the post-pandemic landscape.

Objectives: This study evaluated Quality of Life (QoL) and mental health among nursing technicians in Brazilian Unified Health System (SUS) emergency units, specifically exploring occupational safety and well-being in the post-COVID-19 era. Design: A quantitative, descriptive, exploratory, cross-sectional design was employed. Methods: Data from 146 nursing professionals in Brazilian SUS emergency units were collected remotely during the post-acute pandemic phase (July–Nov 2024). QoL (WHOQOL-BREF) and mental health (HADS) were assessed, followed by descriptive and correlational statistics. Results: The predominantly female, experienced sample showed heterogeneous general QoL but pervasive anxiety, reflecting a sustained psychological burden. Sociodemographic/professional factors had a negligible impact; the emergency environment’s overwhelming influence, intensified by post-pandemic challenges, was key. Psychological distress was strongly negatively correlated with overall QoL and depression in the social domain. Conclusions: The intrinsic nature of emergency work, amplified by persistent psychosocial effects of the global health crisis, drives anxiety and impairs QoL/social relationships. Interventions strengthening QoL, enhancing coping, and adapting work environments to new realities (e.g., loneliness, prolonged mental health impacts) are vital for professional well-being and patient care in this post-pandemic era.
