Many patients who survive a critical illness suffer physical, psychological and cognitive problems, negatively impacting their quality of life, which has been termed Post-ICU Syndrome (PICS). Some studies have reported a residual effect several months after discharge from the ICU, affecting people's quality of life and functionality. Among the psychological symptoms of PICS are described symptoms of depression, anxiety and post-traumatic stress disorder (PTSD). It is estimated that at least 50% of ICU survivors will present psychological symptoms of PICS at discharge and other studies report that a quarter of survivors present PTSD symptoms one year after discharge from the ICU.

Spirituality should be an essential element of health care, as it is part of the essence of being human. International accreditation associations and scientific societies suggest incorporating spiritual care into the usual standards of care. Studies of hospitalized patients have shown that a large percentage of patients consider religion or spirituality to be an important factor in enabling them to cope with serious illness. And although previous studies have shown that chaplain/priest care is associated with increased satisfaction in family members of critically ill patients, the focus has traditionally been on offering support to family members and not to patients. However, there is a growing recognition of the need for a comprehensive approach in health care to provide spiritual support to ICU patients that is evaluated and contributes to improving the quality of life of these individuals. On the other hand, showing the impact of spiritual care on health outcomes of individuals, through studies such as this one, can contribute to a paradigm shift from a biomedical perspective to a holistic view of ICU patients. The technological and advanced life support offered by the ICU is essential for critically ill patients, but the survival of a severe disease without a good quality of life makes it necessary to seek strategies to improve this problem, which undoubtedly requires a comprehensive approach to the person, through medical-physiological care and spiritual care.

The proposed design aims to evaluate the feasibility of implementing a spiritual accompaniment intervention for patients who received care in the ICU, and to begin to implement it during hospitalization. This will provide information regarding the feasibility of implementing an intervention of this type in this context, offering it during hospitalization and its remote implementation process, once the patient is discharged. Considering that these studies work with small samples, it is not necessary to estimate the sample calculation. However, in order to obtain some preliminary results of the effect of the intervention, a sample of 15 people per group will be recruited and followed up until 6 months after discharge, which will allow us to evaluate changes over time in PICS symptoms. It is proposed that the intervention will begin during hospitalization, so that it will have a preventive nature and help mitigate the impact of ICU hospitalization on the development of mental health symptoms in patients. Participants will be randomly assigned to groups and will be evaluated considering intention to treat. On the other hand, gathering the perspective of volunteers, patients and research support team will provide us with inputs to improve the intervention and the best way to implement it.
