Intensive Care Unit Memories and Trauma Triggers for Acute Respiratory Distress Syndrome Survivors Hospitalized During the COVID-19 Pandemic.

Abstract

Background: Intensive care unit (ICU) admissions can be traumatic for critically ill, ventilated acute respiratory distress syndrome (ARDS) patients due to fear of death, an inability to verbally communicate, reliance on health care professionals, and invasive medical interventions. Adult ARDS patients hospitalized during the COVID-19 pandemic were strictly isolated and had limited to no visitation from loved ones, impacting their access to support systems.

Objective: To explore the memories and sensory triggers for them (if applicable) of adult ARDS survivors hospitalized during the COVID-19 pandemic.

Methods: This study used a phenomenological design with an interpretative descriptive approach. Semistructured interviews with open-ended questions were conducted with survivors. Thematic analysis of 16 ARDS survivors' responses to ICU memories and sensory triggers questions was completed to identify the most prevalent themes.

Results: Major themes for vivid memories included (1) altered reality, (2) vivid nonsense dreams, (3) medical treatment/procedures, and (4) feeling lonely/isolated. Themes for triggers included (1) seeing doctors/nurses/hospitals and medical equipment or seeing/hearing media depictions of them, (2) hearing ringtones and beeping/alarms, (3) seeing/hearing helicopters, (4) smelling cleaning products, and (5) seeing/touching scars.

Discussion/conclusions: Fifteen of the 16 ARDS survivors reported traumatic vivid memories, often triggered by sensory stimuli they encountered in their everyday lives. It is important for acute care and outpatient nurses to understand the impact of an ICU admission on ARDS survivors' mental health, so they can adopt evidence-based interventions to prevent or limit these effects.
