Abstract
BACKGROUND Cognitive impairment poses a significant challenge following critical illness in the intensive care unit. A knowledge gap exists concerning how patients experience cognitive impairments. OBJECTIVES The aim was to explore patients' and relatives' experiences of patients' cognitive impairment due to critical illness following an intensive care unit admission. METHODS A qualitative multicentre study was conducted in Denmark with 3- and 6-month follow-ups using single and dyadic interviews. A phenomenological hermeneutic approach was adopted using a Ricoeur-inspired textual in-depth analysis method. The Consolidated Criteria for Reporting Qualitative Research checklist was used. RESULTS Three themes emerged from interviews with 18 patients and 14 relatives: 'It feels like living in a parallel world', 'Getting back to a normal everyday life with a vulnerable self', and 'Managing everyday life using self-invented strategies'. Patients used self-invented strategies to manage their vulnerability and newly acquired cognitive impairments when no help or support was provided specifically targeting their cognitive impairments. Not being as cognitively capable as they previously had been turned their lives upside down. Losing control and not being themselves made them vulnerable. Patients did not want to burden others. However, support from relatives was invaluable in their recovery and rehabilitation. CONCLUSIONS Patients experienced multiple cognitive impairments affecting their adaption to everyday life. They strove to overcome their vulnerability using a variety of self-invented strategies and activities.

Abstract
The purpose of this article was to analyze the concept of "the fighter in the intensive care unit (ICU)" per the scientific literature and the impact this mentality has on care administered in the ICU. A literature review and a concept analysis based on Rodger's evolutionary method were performed to identify surrogate terms, antecedents, attributes, and consequences pertaining to the "fighter" in the ICU. Thirteen articles with a focus on "the fighter" were included in this analysis. There is a strong desire to remain optimistic and maintain high spirits as a coping mechanism in the face of extreme prognostic uncertainty. Themes that emerged from the literature were the need to find inner strength and persist in the face of adversity. The concept of "the fighter in the ICU" can serve as either adaptive or maladaptive coping, depending on the larger clinical picture. Patient experiences in the ICU are fraught with physical and psychological distress. How the patient and family unit cope during this anxiety-provoking time is based on the individual. Maintaining optimism and identifying as a fighter can be healthy ways to adapt to the circumstances. This concept analysis highlights the importance of holistic care and instilling hope particularly as patients may be nearing the end of life.

Intensive Crit Care Nurs 2023; 79:103522. [PMID: 37598502 DOI: 10.1016/j.iccn.2023.103522] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 07/27/2023] [Accepted: 07/30/2023] [Indexed: 08/22/2023]
Abstract
BACKGROUND During the COVID-19 pandemic, patients cared for in the intensive care unit were exposed to many risk factors for developing delirium and subsequent distorted memories. Further, seeing healthcare professionals who have been dressed in personal protective equipment and face masks could have affected the patients' memories. Therefore, the aim of this study was to explore memories and how they are experienced and managed by former patients who have been treated for COVID-19 in an intensive care unit. METHODS Sixteen former patients treated for COVID-19 at a large emergency hospital in Sweden were interviewed 3-8 months after discharge from the intensive care unit. The data were interpreted using thematic analysis. The Consolidated Criteria for Reporting Qualitative Research checklist was followed in the reporting of the study. FINDINGS Participants' descriptions of their memories of treatment in the intensive care unit for COVID-19 generated three themes: 'Distorted truth' the content in the memories which implied facing death in an unreal distorted environment. 'Captive,' was the experience and feelings linked to memories with a feeling of being exposed and alone, and 'Coping with memories' explained how participants managed the implications of the memories using a mixture of strategies. CONCLUSIONS For former patients who were admitted to an intensive care unit after a diagnosis of COVID-19, memories caused considerable distress, which were similar to other intensive care patientś experiences, before the pandemic. Emotion-focused and problem-focused strategies could be used to cope with these memories. Healthcare professionals wearing protective equipment gave the patient a distant feeling, but more important was to be treated with attention/care and respect. IMPLICATIONS FOR CLINICAL PRACTICE Awareness of the impact of distorted memories on patients who are severely ill and their needs and strategies to cope with these memories can form the basis for early interventions that promotes well-being during care and recovery. Healthcare professionals have an important task to inform patients and their family members about the existence of distorted memories, and talk about the patients' experience of them, to facilitate their recovery.

Abstract
BACKGROUND Family members of critically ill patients often experience anxiety when their relatives are transferred from ICU to another level of care. ICU liaison nurse (ICULN) visits have been associated with improved support for patients, their families and nursing staff but has not been extensively studied in the non-English speaking setting. Yet, cross-country variations such as how hospital care is delivered and by who means that innovations such as the ICULN may not be able to be simply transferred to other contexts and may not have similar outcomes. AIM The aim of this study was to investigate family member's experiences with and evaluation of ICULN support service in one Swedish ICU. STUDY DESIGN A qualitative evaluation study was undertaken, recruiting family members of former ICU patients. Audio-taped in-depth interviews were conducted. Data were analysed by content analysis. FINDINGS Fifteen family members were interviewed. Two categories: Minds the gap between intensive care and the next care level and providing stability in an uncertain situation were identified. The ICULN supported the family members both directly, when the ICULNs listened to their questions and met their needs, and indirectly, when the ICULNs took responsibility for the patients and their physical and psychological conditions and wellbeing. CONCLUSION Families valued and were satisfied with the ICULN service but also gave suggestions to improve the service in this particular hospital context. RELEVANCE TO CLINICAL PRACTICE The study showed that an ICULN support service met several needs of family members and therefore was a beneficial way to support patients and family members in the transition from the ICU to the ward.

Abstract
OBJECTIVES Critical illness is a life-threatening condition for the patient, which affects their family members as a traumatic experience. Well-known long-term consequences include impact on mental health and health-related quality of life. This study aims to develop a grounded theory to explain pattern of behaviours in family members of critically ill patients cared for in an intensive care unit, addressing the period from when the patient becomes critically ill until recovery at home. RESEARCH METHODOLOGY/DESIGN We used a classic grounded theory to explore the main concern for family members of intensive care patients. Fourteen interviews and seven observations with a total of 21 participants were analysed. Data were collected from February 2019 to June 2021. SETTING Three general intensive care units in Sweden, consisting of a university hospital and two county hospitals. FINDINGS The theory Shifting focus explains how family members' main concern, living on hold, is managed. This theory involves different strategies: decoding, sheltering and emotional processing. The theory has three different outcomes: adjusting focus, emotional resigning or remaining in focus. CONCLUSION Family members could stand in the shadow of the patients' critical illness and needs. This emotional adversity is processed through shifting focus from one's own needs and well-being to the patient's survival, needs and well-being. This theory can raise awareness of how family members of critically ill patients manage the process from critical illness until return to everyday life at home. Future research focusing on family members' need for support and information, to reduce stress in everyday life, is needed. IMPLICATIONS FOR CLINICAL PRACTICE Healthcare professionals should support family members in shifting focus by interaction, clear and honest communication, and through mediating hope.

Abstract
INTRODUCTION Physical therapists supporting patients in intensive care unit (ICU) rehabilitation can improve their clinical practice with insight in patients' lived body experiences. OBJECTIVE To gain insight in patients' lived body experiences during ICU stay and in recovery from critical illness. METHODS Through a comprehensive systematic literature search, 45 empirical phenomenological studies were identified. Patients' lived body experiences were extracted from these studies and synthesized following the seven-phase interpretative approach as described by Noblit and Hare. RESULTS Three lines of argument were illuminated: 1) "recovery from critical illness starts from a situation in which patients experience the lived body as unable;" 2) "patients experience progress in recovery from critical illness when the lived body is empowered;" and 3) "recovery from critical illness results in a lived body changed for life." Eleven third-order constructs were formulated as different kinds of bodies: 1) "an intolerable body;" 2) "an alienated body;" 3) "a powerless body;" 4) "a dependent body;" 5) "a restricted body;" 6) "a muted body;" 7) "a touched body;" 8) "a transforming body;" 9) "a re-discovering body;" 10) "an unhomelike body;" and 11) "a remembering body." CONCLUSION Patients' lived body experiences during ICU stay and in recovery from critical illness have richly been described in phenomenological studies and were synthesized in this meta-ethnography.

Longing for homelikeness: A hermeneutic phenomenological analysis of patients' lived experiences in recovery from COVID-19-associated intensive care unit acquired weakness. J Adv Nurs 2022; 78:3358-3370.

Abstract
Aims To explore lived experiences of patients recovering from COVID‐19‐associated intensive care unit acquired weakness and to provide phenomenological descriptions of their recovery. Design A qualitative study following hermeneutic phenomenology. Methods Through purposeful sampling, 13 participants with COVID‐19‐associated intensive care unit acquired weakness were recruited with diversity in age, sex, duration of hospitalization and severity of muscle weakness. Semi‐structured in‐depth interviews were conducted from 4 to 8 months after hospital discharge, between July 2020 and January 2021. Interviews were transcribed verbatim and analysed using hermeneutic phenomenological analysis. Results The analysis yielded five themes: ‘waking up in alienation’, ‘valuing human contact in isolation’, ‘making progress by being challenged’, ‘coming home but still recovering’ and ‘finding a new balance’. The phenomenological descriptions reflect a recovery process that does not follow a linear build‐up, but comes with moments of success, setbacks, trying new steps and breakthrough moments of achieving mobilizing milestones. Conclusion Recovery from COVID‐19‐associated intensive care unit acquired weakness starts from a situation of alienation. Patients long for familiarity, for security and for recognition. Patients want to return to the familiar situation, back to the old, balanced, bodily self. It seems possible for patients to feel homelike again, not only by changing their outer circumstances but also by changing the understanding of themselves and finding a new balance in the altered situation. Impact Muscle weakness impacts many different aspects of ICU recovery in critically ill patients with COVID‐19‐associated intensive care unit acquired weakness. Their narratives can help nurses and other healthcare professionals, both inside and outside of the intensive care unit, to empathize with patient experiences. When healthcare professionals connect to the lifeworld of patients, they will start to act and communicate differently. These insights could lead to optimized care delivery and meeting patients' needs in this pandemic or a possible next.

Abstract
OBJECTIVES The aim of this study was to investigate health-related quality of life (HRQOL) and related factors in intensive care unit survivors one-12 months after discharge. RESEARCH METHODOLOGY/DESIGN This cross-sectional survey included survivors who had been admitted to an intensive care unit for ≥48 hours. MAIN OUTCOME MEASURES HRQOL was measured using the EQ-5D-5L profile, which evaluates five dimensions of health (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) on five levels (no, slight, moderate, severe, and extreme problems), EQ-VAS (score range 0-100, 100 indicating best health) and EQ values (score range -0.066-1, 1 indicating best health). The factors influencing HRQOL were analyzed by Tobit regression. SETTING Survivors treated in an intensive care unit at six institutions in Korea. RESULTS Only 7.9% of the 534 participants had self-reported profiles of no health problems in all five dimensions. The proportion of participants with slight problems was highest in pain/discomfort with 85.0%. The proportion with severe problems was highest in usual activities with 21.7%, followed by mobility with 21.0%. The median and interquartile range of the EQ-VAS and EQ values were 60.00 (45.00 to 75.00) and 0.72 (0.52 to 0.80), respectively. Negative impact factors on HRQOL included older age, women, residing in a long term care facility, unemployment, emergency intensive care admission, and intensive care stay ≥ 7 days. CONCLUSION HRQOL among Korean intensive care survivors is low. The level of problems in physical dimensions is more severe than that in mental health dimensions. Early rehabilitation in the intensive care unit should be provided to facilitate long-term recovery.

Abstract
OBJECTIVES To illuminate patients' experiences of being a part of an liaison nurse support service focused on supporting recently transferred intensive care unit patients. RESEARCH METHODOLOGY/DESIGN A qualitative inductive descriptive design including in-depth interviews was chosen. SETTING A project including an liaison nurse support service-intervention was undertaken during a 16-week period at a University hospital in Sweden. The liaison nurse support service was available Monday-Friday 10 am - 6 pm and nurses visited the patient 1-4 times after transfer to the ward. MAIN OUTCOME MEASURES Of the 109 patients who were visited by the liaison nurse support service, 14 agreed to be interviewed about their experiences of the transfer. Data was analysed by inductive content analysis. FINDINGS One overall theme, An advocate in a vulnerable situation emerged from the data. Four subthemes were identified: Ensures transfer of information between the intensive care unit and the general ward, Makes the circumstances understandable and coordinates between the care levels and Offers emotional support and stability in an uncertain situation. CONCLUSION The liaison nurse support service contributed to ensuring accurate transfer of information, solved problems when the patient themselves did not have control or strength and provided emotional support.
