The experience of a loved one's stay in a COVID-19 intensive care unit (ICU), either intubated or on respiratory support, forces family caregivers (hereafter 'caregivers') to face core existential fears, such as uncertainty and death. It also poses a serious threat to basic human needs for autonomy, competence, and relatedness, as family caregivers have no control over the illness, and limited prior competence in dealing with critical illness. COVID-19 likely aggravates this experience, as social distancing cuts caregivers off from visiting patients in the ICU, from using their usual social supportive network and the threat of infection extends to caregivers themselves, their children and family. Combined, these extreme circumstances put caregivers in emotional turmoil and in need of psychological support and assistance in managing difficult emotions. ICU caregivers are at risk of developing clinically relevant symptoms of anxiety or posttraumatic stress. During the patient's ICU stay, caregivers experience peri-traumatic distress, such as helplessness, grief, frustration and anger, that may predict later posttraumatic stress disorder (PTSD). Symptoms of anxiety and PTSD may last for months to years after the patient's discharge. Further, caregivers of patients who die in an ICU may be at greater risk of prolonged grief disorder. Supportive interventions may reduce psychological late effects in ICU caregivers, but the primary focus of the majority of interventions has been on communication or surrogate decision making. The CO-CarES study aims to develop and test the feasibility of a tele-delivered psychological intervention to enable caregivers of ICU patients with COVID-19 to better endure the overwhelming uncertainty and emotional strain and reduce the risk of posttraumatic stress and prolonged grief. The study hypothesizes that providing psychological intervention during and after the patients' hospitalization, can decrease peri-traumatic distress during ICU hospitalization and decrease risk of post-traumatic stress, anxiety, depression and perceived stress following discharge, as well as prolonged grief in bereavement. A secondary hypothesis is that changes in emotion regulation mediate effects of the intervention on long-term psychological outcomes.
