Acute confusion and unreal experiences in intensive care patients in relation to the ICU syndrome. Part II

Patients' Dreams and Unreal Experiences During Intensive Care Unit (ICU) Hospitalization

In the intensive care unit (ICU), patients often experience fragmented memories, primarily comprising dreams and illusions. These experiences can impact psychosocial well-being, correlating with post-traumatic stress symptoms and heightened anxiety. Understanding these phenomena is crucial for holistic care. To systematically explore patients' perspectives concerning the recollection of dreams and unreal encounters during their stay in the ICU, considering pertinent clinical conditions and potential influencing factors, we conducted a comprehensive search in the PubMed/MEDLINE, Web of Science, and Scopus databases until November 20, 2023, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. From an initial pool of 288 records, a thorough screening for eligibility resulted in the inclusion of nine studies for this systematic review. These selected studies underwent evaluation using either the Critical Appraisal Skills Programme (CASP) Qualitative Checklist or the Newcastle-Ottawa Scale (NOS). All studies categorized dreams into three main types: positive, distressing (including nightmares), and neutral experiences. These were further detailed based on aspects such as time, space, senses, emotions, and distinguishing between reality and unreality. Two studies found associations between dreams and conditions like Guillain-Barré syndrome (GBS), mental abnormalities, and delirium. In one study, GBS patients had more vivid dreams, hallucinations, and delusions compared to ICU control group patients; delirious patients tend to report more frequent frightening dreams. Patients in the ICU who recalled dreams often had more severe illness, longer stays, and higher ventilation frequency. Notably, a prolonged ICU stay significantly predicted the likelihood of dream recall, as consistently observed in three other studies. This suggests that patients with prolonged ICU stays, experiencing higher dream recall, underwent extended treatments. This systematic exploration of patients' perspectives on fragmented memories underscores the connections between these experiences, clinical conditions such as GBS and delirium, and extended ICU stays. Recognizing and attending to these psychological aspects in post-ICU care is critical for alleviating the enduring emotional consequences for patients.

Social isolation at the end of life: A case report of one person's journey navigating the medical landscape during the COVID-19 pandemic

BACKGROUND

In addition to physical symptom burden, psychological suffering at end of life (EOL) is quite pervasive. As such, the interdisciplinary team in our Palliative and Supportive Care Unit strives to provide quality care sensitive to the physical and psychosocial needs of patients. Involving and allowing for the presence of family members is one way in which we afford our patients some additional comfort. Unfortunately, the current pandemic has placed limitations on this rather fundamental need for both patients and their family members. Here, we present a case illustrating the effects of visitor restrictions/isolation due to COVID-19 on the suffering of a patient at the EOL.

CASE DESCRIPTION

A male in his 20s with a refractory hematologic malignancy decided to pursue a comfort-based approach to care after a rapid clinical deterioration. Due to visitor restrictions, he had to face this decision with limited support at the bedside, which caused significant distress. He was forced to choose among several immediate family members who would be at his side through his hospitalization, to be his advocate, at times his voice, his confidant, and the person to relay all information to those on the outside. He expressed a wish to be married before he died, which occurred in our palliative care unit. This life goal was one we would normally encourage those he loved to gather around him, but this was not possible. He passed peacefully two days after he was married.

CONCLUSION

Although social limitations are necessary to help provide safety to the patients and staff in a hospital, they can have a direct impact on the suffering of patients and families at the EOL. Helping to maintain dignity, reflect on their life, and resolve any conflicts in the presence of family members is a benchmark for providing quality palliative care. Being barred from visitation due to isolation, threatens this care and lays the foundation for complicated grief among family members. Further research is needed to help balance the needs of those at the EOL with public safety. One such measure to help ease distress is to allow for more virtual visitation through electronic measures.

Delirium-related distress in the ICU: A qualitative meta-synthesis of patient and family perspectives and experiences

BACKGROUND

Better understanding of patient and family member experiences of delirium and related distress during critical care is required to inform the development of targeted nonpharmacologic interventions.

OBJECTIVE

To examine and synthesize qualitative data on patient and family member delirium experiences and relieving factors in the Intensive Care Unit (ICU).

DESIGN

We conducted a systematic review and qualitative meta-synthesis. Eligible studies contained adult patient or family quotes about delirium during critical care, published in English in a peer-reviewed journal since 1980. Data sources included PubMed, Embase, CINAHL, PsycINFO, Web of Science, Cochrane and Clinicaltrials.gov.

METHODS

Systematic searches yielded 3238 identified articles, of which 14 reporting 13 studies were included. Two reviewers independently extracted data into a Microsoft Excel spreadsheet. Qualitative meta-synthesis was performed through line-by-line coding of relevant quotes, organization of codes into descriptive themes, and development of analytical themes. Five patients/family members with experience of ICU delirium contributed to the thematic analysis.

RESULTS

Qualitative meta-synthesis resulted in four major themes and two sub-themes. Key new patient and family-centric insights regarding delirium-related distress in the ICU included articulation of the distinct emotions experienced during and after delirium (for patients, predominantly fear, anger and shame); its 'whole-person' nature; and the value that patients and family members placed on clinicians' compassion, communication, and connectedness.

CONCLUSIONS

Distinct difficult emotions and other forms of distress are experienced by patients and families during ICU delirium, during which patients and families highly value human kindness and empathy. Future studies should further explore and address the many facets of delirium-related distress during critical care using these insights and include patient-reported measures of the predominant difficult emotions.

Patients' experiences of delirium: A systematic review and meta-summary of qualitative research

AIMS

The purpose of this systematic review and meta-summary was the aggregation of the empirical qualitative literature on patients' experiences of delirium in order to support the development and implementation of patient-oriented delirium management and to guide future research.

DESIGN

We conducted a systematic literature review of qualitative research published between January 1980 and June 2019.

DATA SOURCES

In June 2019, we searched in Medline, CINAHL, SSCI and PsycInfo to identify relevant reports. In addition, we conducted searches in three dissertation databases (BASE, DART and ProQuest) and Google Scholar.

REVIEW METHODS

We used methods developed by Sandelowski and Barroso to construct a meta-summary of the findings by extracting them from the reports, abstracting them into meta- findings and calculating their manifest interstudy frequency effect sizes.

RESULTS

Out of the 742 identified records, 24 reports based on delirium experience accounts of 483 patients met our criteria and were included. One thousand ninety-seven findings were extracted from these reports and abstracted into 92 meta-findings. These were grouped to the five emerging themes 'perception', 'emotions', 'interaction with others', 'dealing with delirium' and 'influence on further life'.

CONCLUSION

Delirium is commonly perceived as an overall distressing condition, which can accompany and influence patients even after hospital discharge.

IMPACT

This systematic review and meta-summary is the most comprehensive aggregation of qualitative research of the patient delirium experience to date. It allows us to better understand, extract meaning from, and weigh the qualitative findings in their context by calculating their manifest frequency effect sizes. This can be used to support the development and implementation of delirium management concepts.

The Family and Safety of the Hospitalized Patient: An Integrative Literature Review

<b><i>Framework:</i></b> Considering that the current data on health care safety remain alarming, there is an overwhelming urge for the ongoing study of this topic and for recommendations and differentiated strategies which aim to promote health and which prove effective. Some recommendations have been taken into consideration, such as patient-centered care, and consequently the need for greater involvement of patient and family in this process. However, we have identified arguments for and against the involvement of family in the care process, and consequently a greater or lesser openness towards hospital visits. <b><i>Objective:</i></b> What are the implications of the presence of family for the safety of hospitalized patients? What does the science say about these implications? <b><i>Methods:</i></b> We conducted an integrative literature review by referring to the Web of Science, CINAHL, Medline, and Scopus databases, according to the recommendations of the Joanna Briggs Institute for scoping review. <b><i>Results:</i></b> We found 115 articles. After selection, 13 articles were included in this review. There were 6 qualitative studies, 5 quantitative studies, and 2 literature reviews. Data were grouped according to: the perspective of patients and their families, the health professionals’ perspective, and statistical evidence. <b><i>Conclusion:</i></b> Families take efforts to protect the safety of hospitalized patients but feel unprepared; a lack of follow-up was reported. Some health professionals claim that the presence of the family can increase the risks for patient safety and the fear of an increased workload. The evidence of the presence of the family and its link to the safety of the hospitalized patient demonstrated that this relationship is not yet well understood. There were limited findings about this in the current literature. <b><i>Relevance to Clinical Practice:</i></b> Structured interventions about family integration in ensuring the safety of hospitalized patients may have the potential to contribute to the safety of health care.

Distorted Memories and Related Factors in ICU Patients

This study aimed to examine the relationship between memory status of and factors related to patients in the intensive care unit (ICU) using a cross-sectional study design. Participants were adult patients who were admitted to the general ICUs for more than 48 hours. One week after ICU discharge, a survey on memory distortion was conducted. Overall, 133 patients were included, of whom 51.1% reported distorted memories. Among them, 15.0% had memory loss; 48.1% had unrealistic experiences; 27.8% recalled confusion, panic, anxiety, and discomfort during their ICU stay; and 9% had traumatic experiences. Multiple logistic regression analyses revealed that memory loss was associated with an operation, and a significant association was observed between traumatic memory and pain. Opioid use may have a protective effect against memory loss. These results suggest the importance of relieving pain and preserving true memories during ICU treatment.

Strategies for communicating with conscious mechanically ventilated critically ill patients

Critically ill patients admitted to the intensive care unit (ICU) frequently require ventilatory support. To provide this life-saving therapy, oral intubation or tracheostomy placements are needed. Consequently, verbal ability to communicate is lost. Furthermore, depending on the severity of the clinical condition and other comorbidities, patients commonly develop ICU-acquired weakness, which may preclude gestural communication and motor abilities. Under this circumstance, the patient's inability to interact with health care providers and/or family members results in psychological alterations, as well as isolation and reduction of self-esteem. A variety of tools have been developed to improve patient-clinician communication. This article reviews patient complications due to lack of communication, available tools to enhance interactions, and current published evidence to support communication tools.

Clinical Practice Guidelines for the Prevention and Management of Pain, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU

OBJECTIVE

To update and expand the 2013 Clinical Practice Guidelines for the Management of Pain, Agitation, and Delirium in Adult Patients in the ICU.

DESIGN

Thirty-two international experts, four methodologists, and four critical illness survivors met virtually at least monthly. All section groups gathered face-to-face at annual Society of Critical Care Medicine congresses; virtual connections included those unable to attend. A formal conflict of interest policy was developed a priori and enforced throughout the process. Teleconferences and electronic discussions among subgroups and whole panel were part of the guidelines' development. A general content review was completed face-to-face by all panel members in January 2017.

METHODS

Content experts, methodologists, and ICU survivors were represented in each of the five sections of the guidelines: Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption). Each section created Population, Intervention, Comparison, and Outcome, and nonactionable, descriptive questions based on perceived clinical relevance. The guideline group then voted their ranking, and patients prioritized their importance. For each Population, Intervention, Comparison, and Outcome question, sections searched the best available evidence, determined its quality, and formulated recommendations as "strong," "conditional," or "good" practice statements based on Grading of Recommendations Assessment, Development and Evaluation principles. In addition, evidence gaps and clinical caveats were explicitly identified.

RESULTS

The Pain, Agitation/Sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) panel issued 37 recommendations (three strong and 34 conditional), two good practice statements, and 32 ungraded, nonactionable statements. Three questions from the patient-centered prioritized question list remained without recommendation.

CONCLUSIONS

We found substantial agreement among a large, interdisciplinary cohort of international experts regarding evidence supporting recommendations, and the remaining literature gaps in the assessment, prevention, and treatment of Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) in critically ill adults. Highlighting this evidence and the research needs will improve Pain, Agitation/sedation, Delirium, Immobility (mobilization/rehabilitation), and Sleep (disruption) management and provide the foundation for improved outcomes and science in this vulnerable population.

The lived experience of delirium in intensive care unit patients: A meta-ethnography

OBJECTIVES

The objectives were to interpretatively synthesise qualitative findings on patients' lived experience of delirium in the intensive care unit (ICU) and to identify meanings and potential existential issues that affect them during and after their experience. Patients may face existential challenges when they are vulnerable in their confusion, all while confronting the reality of their mortality in the critically ill state.

REVIEW METHODS

The study involved meta-ethnographic synthesis of published qualitative studies addressing the lived experience of delirium for patients in ICU based on a systematic literature search.

DATA SOURCES

MEDLINE, PsycINFO, Embase, Scopus, CINAHL, ProQuest, and Cochrane were the sources. Studies were selected based on the predefined inclusion/exclusion criteria. The identified studies were subjected to a quality appraisal based on a Critical Appraisal Skills Programme tool.

RESULTS

Based on the eligibility criteria, nine qualitative studies were included, of overall medium to high quality. One core theme, "a perturbing altered reality" and four main themes were identified: "disturbed sense of time", "omnipresent feeling of fear", "impact of human connection", and "perceiving surreal events". These four themes illustrate how the three salient existential issues of uncertainty, self-perceived helplessness, and death that are present in delirium make it a highly distressing experience for patients in ICU.

CONCLUSIONS

Critically ill patients who experience delirium appear to face intense existential issues, which may not be identified by care providers and may remain unaddressed during their ICU stay and after discharge. Patients report that addressing the memories of these issues would be therapeutic. Future research needs to explore care approaches to meet the unique psychosocial needs of critically ill patients with delirium.

Neuropathic pain in a rehabilitation setting after spinal cord injury: an interpretative phenomenological analysis of inpatients' experiences

Study design

Qualitative, semi-structured interviews.

Objectives

Neuropathic pain (NP) can be psychologically and physically debilitating, and is present in approximately half of the spinal cord injured (SCI) population. However, under half of those with NP are adherent to pain medication. Understanding the impact of NP during rehabilitation is required to reduce long-term impact and to promote adherence to medication and psychoeducation recommendations.

Setting

United Kingdom.

Methods

Five males and three females with SCI and chronic NP, resident in rehabilitation wards at a specialist SCI center in the United Kingdom, took part. Semi-structured interviews were conducted with participants less than 15 months post-SCI (mean = 8.4 months). Verbatim transcripts were subject to interpretative phenomenological analysis (IPA).

Results

Three super-ordinate themes were identified, mediating pain and adherence: (1) the dichotomy of safety perceptions; (2) adherence despite adversity; and (3) fighting the future. Analyses suggest that experience of the rehabilitation setting and responsiveness of care shapes early distress. Attitudes to medication and psychosocial adjustment are relevant to developing expectations about pain management.

Conclusions

Enhancing self-efficacy, feelings of safety in hospital, and encouraging the adoption of adaptive coping strategies may enhance psychosocial and pain-related outcomes, and improve adherence to medication. Encouraging adaptive responses to, and interpretation of, pain, through the use of interventions such as coping effectiveness training, targeted cognitive behavioral pain management, and acceptance-based interventions such as mindfulness, is recommended in order to reduce long-term reliance on medication.

"Eight Days of Nightmares … " - Octogenarian Patients' Experiences of Postoperative Delirium after Transcatheter or Surgical Aortic Valve Replacement

BACKGROUND

Surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI) are increasingly performed in octogenarian patients with severe aortic stenosis (AS), including those with high surgical risk. Postoperative delirium (PD) is a common and serious complication in older patients, characterised by reduced awareness, change in consciousness, disturbance in logical thinking and hallucinations.

METHODS

To explore how octogenarian patients experienced PD, a qualitative study was conducted including five women and five men between 81 and 88 years. The incidence of PD was assessed for five days using the Confusion Assessment Method. Cognitive function was assessed preoperatively and at a 6-month follow-up using the Mini-Mental State Examination. In-depth interviews were conducted 6-12 months post-discharge, transcribed, and analysed using Giorgi's phenomenological method.

RESULTS

Postoperative delirium experiences were grouped into six themes: "Like dreaming while awake", "Disturbed experiences of time", "Existing in a twilight zone", "Trapped in medical tubes", "Moving between different surroundings" and "Meeting with death and the deceased".

CONCLUSIONS

For the first time, we show that octogenarian patients who undergo SAVR or TAVI have strong and distressing memories of their delirious state that can persist for up to 12 months later. These findings provide valuable new information that will likely improve delivery of health services and enhance professional and empathic care of octogenarians after SAVR and TAVI.

Sedation of Patients in Intensive Care Medicine and Nursing: ethical issues

This article focuses on the ethical aspects of medically-induced sedation and pain relief in intensive care medicine. The study results reported are part of a larger investigation of patients’ experiences of being sedated and receiving pain relief, and also families’ experiences of having a close relative under controlled sedation in an intensive care unit.

The study is based on qualitative in-depth interviews with nine nurses and six doctors working in intensive care and surgical units in a major Norwegian hospital. The textual data are interpreted according to Kvale’s method for analyzing qualitative data.

There are ethical problems regarding how to achieve an acceptable balance between a patient’s subjective well-being and the medical need for reduced sedation. The authors discuss whether some medical reasons for reduced sedation are ethically justifiable, given the actual medical knowledge available. The study also addresses the ethical consequences of reducing medically-induced sedation and the demands it puts on interdisciplinary co-operation and communication, as well as the importance of improving the quality of medical and nursing care.

Recall of ICU Stay in Patients Managed With a Sedation Protocol or a Sedation Protocol With Daily Interruption

OBJECTIVES

To 1) describe factual, emotional, and delusional memories of ICU stay for patients enrolled in the SLEAP (Daily sedation interruption in mechanically ventilated critically ill patients cared for with a sedation protocol) trial; 2) compare characteristics of patients with and without ICU recall, and patients with and without delusional memories; and 3) determine factors associated with delusional memories 28 days after ICU discharge.

DESIGN

Prospective cohort.

SETTING

Sixteen North American medical and surgical ICUs.

PATIENTS

Critically ill, mechanically ventilated adults randomized in the SLEAP trial.

INTERVENTIONS

Post-ICU interviews on days 3, 28, and 90 using the validated ICU Memory Tool.

MEASUREMENTS AND MAIN RESULTS

Overall, 289 of 297 ICU survivors (97%) (146 protocolized sedation and 143 protocolized sedation plus daily interruption patients) were interviewed at least once. Because there were no differences in recall status or types of memories between the two sedation groups, we present the findings for all patients rather than by study group. On days 3, 28, and 90, 28%, 26%, and 36% of patients, respectively, reported no recall of being in the ICU (overall perception, self-reported) (p = 0.75). Mean daily doses of benzodiazepines and opioids were lower in patients with no ICU recall than those with recall (p < 0.0001 for both). Despite one third of patients reporting no recall of ICU stay on day 3, 97% and 90% reported at least one factual and one emotional memory from ICU, respectively. Emotional memories declined with time after ICU discharge, particularly panic and confusion. Delusional memories 28 days after discharge were common (70%) yet unrelated to delirium (p = 0.84), recall status (p = 0.15), total dose of benzodiazepine (p = 0.78), or opioid (p = 0.21). Delusional memories were less likely with longer duration of mechanical ventilation (odds ratio, 0.955; 95% CI, 0.91-1.00; p = 0.04).

CONCLUSIONS

Recall of ICU stay and types of memories reported were not influenced by the trial sedation strategy. Lack of ICU recall and delusional memories were common after ICU discharge despite the use of sedation strategies that promoted wakefulness.

Making sense of it: intensive care patients' phenomenological accounts of story construction

BACKGROUND

Patients entering intensive care encounter physical and psychological stress that may lead to psychological morbidity such as depression, anxiety and post-traumatic stress. It has been suggested that constructing a story may assist psychological recovery. However, this has been minimally investigated in intensive care patients.

AIM

The aim of this article is to examine the process of story construction in people's phenomenological accounts of being a patient in the technological environment of intensive care.

STUDY DESIGN

The study design was informed by Heideggerian phenomenology.

METHODS

Semi-structured interviews were conducted with 19 patients who had been in intensive care for at least 4 days. Interviews were digitally recorded, transcribed and analysed utilizing Van Manen's framework for thematic analysis.

FINDINGS

Making sense of their experiences in an intensive care unit appeared to be fundamental to story construction. Themes that arose were 'why am I here?', 'filling in the gaps', 'sorting the real from the unreal' and 'searching for familiarity'. These themes describe how participants sought temporal and causal coherence in order to construct their integrated and understandable story. Families appeared to play a critical role in helping participants fill in the gaps, sorting the real from the unreal and their subsequent psychological recovery.

CONCLUSIONS AND RELEVANCE TO CLINICAL PRACTICE

The importance of early support from health care professionals to facilitate patients' story construction is highlighted. The study also emphasizes the role families play in supporting patients while they make sense of their experiences and the associated psychological recovery process. Further research to evaluate methods of facilitating story construction, such as nurse-led debriefing and patient diaries, is recommended. In addition, an investigation of families' perceptions of their role in assisting patients construct their story may facilitate the development of strategies by health care professionals to effectively support families in their role.

Experiences of undergoing cardiac surgery among older people diagnosed with postoperative delirium: one year follow-up

Background

Cardiovascular disease is common among old people and many undergo cardiac surgery. Scientific knowledge is available on cardiac surgery from several perspectives. However, we found few studies focusing on older patients’ experiences of cardiac surgery. The aim of this study was to illuminate experiences of undergoing cardiac surgery among older people diagnosed with postoperative delirium, a one year follow-up.

Methods

Qualitative interviews were conducted with 49 participants (aged ≥70 years) diagnosed with delirium after cardiac surgery. Data were collected in Sweden during 2010 through individual, semi-structured interviews in participants’ homes one year after surgery. The interviews were analyzed using qualitative content analysis.

Results

Four themes with sub-themes were formulated: Feeling drained of viability includes having a body under attack, losing strength and being close to death. Feeling trapped in a weird world describes participants having hallucinations, being in a nightmare and being remorseful for their behavior. Being met with disrespect includes feeling disappointed, being forced, and feeling like cargo. On the other hand, Feeling safe, including being in supportive hands and feeling grateful, points to participants’ experiences of good care and the gift of getting a second chance in life.

Conclusions

Even one year after cardiac surgery, participants described in detail feelings of extreme vulnerability and frailty. They also had felt completely in the hands of the health care professionals. Participants described experiences of hallucinations and nightmares during hospitalization. Cardiac surgery was a unique, fearful, traumatic and unpleasant experience yet could also include pleasant or rewarding aspects. It seems that health care professionals need deeper knowledge on postoperative delirium in order to prevent, detect and treat delirium to avoid and relieve the suffering these experiences might cause.

The experience of communication difficulties in critically ill patients in and beyond intensive care: Findings from a larger phenomenological study

Communication difficulties in intensive care units (ICU) with critically ill patients have been well documented for more than three decades. However, there is only a paucity of literature that has explored communication difficulties beyond the ICU environment. This paper discusses the experience of communication difficulties in critically ill patients in ICU and beyond as part of findings from a larger study that explored the lived experiences of critically ill patients in ICU in the context of daily sedation interruption (DSI). The aim of the study was to describe the lived experience of people who experienced critical illness in ICU using a hermeneutic phenomenological approach in the DSI context. Twelve participants aged between 20 and 76 years with an ICU stay ranging from 3 to 36 days were recruited from a 16 bed ICU in a large regional referral hospital in New South Wales (NSW), Australia. Participants were intubated, mechanically ventilated and subjected to (DSI) during their critical illness in ICU. In-depth face to face interviews with participants were conducted at two weeks after discharge from ICU and at six to eleven months later. Interviews were audio taped and transcribed. Thematic analysis using van Manen's (1990) method was completed. The overarching theme; 'Being in limbo' and subthemes 'Being disrupted'; 'Being imprisoned' and 'Being trapped' depict the main elements of the experience. This paper discusses communication difficulties in critically ill patients as one of the main findings relating to the theme 'Being trapped'. Participants' reports of communication difficulties in ICU are similar to those reported by patients in other studies where DSI was not used. However, not many studies have reported ongoing communication difficulties after ICU hospitalisation. Recommendations are made for new models of care and support to mitigate critically ill patients' communication concerns in ICU and for further research into the causes and treatment to benefit this group of patients. Most importantly, extra care is recommended not to damage vocal cords during intubation and cuff inflation in the course of mechanical ventilation.

‘A post-transplant person’: Narratives of heart or lung transplantation and intensive care unit delirium

Exploring patients’ narratives can lead to new understandings about perceived illness states. Intensive Care Unit delirium is when people experience transitory hallucinations, delusions or paranoia in the Intensive Care Unit and little is known about how this experience affects individuals who have had a heart or lung transplant. A total of 11 participants were recruited from two heart and lung transplant services and were invited to tell their story of transplant and Intensive Care Unit delirium. A narrative analysis was conducted and the findings were presented as a shared story. This shared story begins with death becoming prominent before the transplant: ‘you live all the time with Mr Death on your shoulder’. Following the operation, death permeates all aspects of dream worlds, as dreams in intensive care ‘tunes into the subconscious of your fears’. The next part of the shared story offers hope of restitution; however, this does not last as reality creeps in: ‘I thought it was going to be like a miracle cure’. Finally, the restitution narrative is found to be insufficient and individuals differ in the extent to which they can achieve resolution. The societal discourse of a transplant being a ‘gift’, which gives life, leads to internalised responsibility for the ‘success’ or ‘failure’ of the transplant. Participants describe how their experiences impact their sense of self: ‘a post-transplant person’. The clinical implications of these findings are discussed.

Nurses' perceptions of unpleasant symptoms and signs in ventilated and sedated patients

AIMS AND OBJECTIVES

To describe intensive care nurses' perceptions and assessments of unpleasant symptoms and signs in mechanically ventilated and sedated adult intensive care patients.

BACKGROUND

Mechanically ventilated patients are unable to express themselves verbally and depend upon nurses to control their symptoms by understanding their unpleasant experiences, such as pain, anxiety or delirium and interpret the relevant signs. Nurses must have enough knowledge to adjust their analgesics and sedatives appropriately and to avoid under- or oversedation.

DESIGN

A cross-sectional survey design.

METHODS

A study with a self-administrated questionnaire was undertaken in October 2007 to February 2008, with a convenience sample of 183 intensive care nurses in Norway.

RESULTS

The questionnaire was completed by 86 (47%) nurses. Most perceived that critical illness polyneuropathy/myopathy occurred frequently. Half the nurses underestimated pain, anxiety and delirium. Signs such as a response to contact, cough reflex, wakefulness and muscle tone were considered most important in assessing oversedation. Agitation, facial grimacing, tube intolerance and wakefulness were considered most important in assessing undersedation. The Comfort Scale and Adoption of the Intensive Care Environment corresponded best to the signs identified by the nurses.

CONCLUSION

The nurses underestimated unpleasant symptoms other than critical illness polyneuropathy/myopathy. A further mapping of patients' experiences should be conducted, with an emphasis on the more 'silent' distressing symptoms. Further tools to facilitate the communication of consciousness levels and the intolerance of unpleasant symptoms must be developed and implemented.

RELEVANCE TO CLINICAL PRACTICE

A deeper understanding of unpleasant symptoms and signs focused in learning activities may help nurses to recognize patients' early problems and allow targeted interventions. A more active stimulus-response assessment of ICU patients is required to detect oversedation, critical illness polyneuropathy/myopathy and hypoactive delirium. Assessment tools should reflect both the patient's tolerance of various unpleasant symptoms and the level of consciousness.

The "Truman Show" delusion: psychosis in the global village

INTRODUCTION

We report a novel delusion, primarily persecutory in form, in which the patient believes that he is being filmed, and that the films are being broadcast for the entertainment of others.

METHODS

We describe a series of patients who presented with a delusional system according to which they were the subjects of something akin to a reality television show that was broadcasting their daily life for the entertainment of others. We then address three questions, the first concerning how to characterise the delusion, the second concerning the role of culture in delusion, and the third concerning the implications of cultural studies of delusion for the cognitive theory of delusion.

RESULTS

Delusions are both variable and stable: Particular delusional ideas are sensitive to culture, but the broad categories of delusion are stable both across time and culture. This stability has implications for the form a cognitive theory of delusion can take.

CONCLUSIONS

Cultural studies of delusion have important contributions to make to the cognitive theory of delusion.

Investigating risk factors for psychological morbidity three months after intensive care: a prospective cohort study

INTRODUCTION

There is growing evidence of poor mental health and quality of life among survivors of intensive care. However, it is not yet clear to what extent the trauma of life-threatening illness, associated drugs and treatments, or patients' psychological reactions during intensive care contribute to poor psychosocial outcomes. Our aim was to investigate the relative contributions of a broader set of risk factors and outcomes than had previously been considered in a single study.

METHODS

A prospective cohort study of 157 mixed-diagnosis highest acuity patients was conducted in a large general intensive care unit (ICU). Data on four groups of risk factors (clinical, acute psychological, socio-demographic and chronic health) were collected during ICU admissions. Post-traumatic stress disorder (PTSD), depression, anxiety and quality of life were assessed using validated questionnaires at three months (n = 100). Multivariable analysis was used.

RESULTS

At follow-up, 55% of patients had psychological morbidity: 27.1% (95% CI: 18.3%, 35.9%) had probable PTSD; 46.3% (95% CI: 36.5%, 56.1%) probable depression, and 44.4% (95% CI: 34.6%, 54.2%) anxiety. The strongest clinical risk factor for PTSD was longer duration of sedation (regression coefficient = 0.69 points (95% CI: 0.12, 1.27) per day, scale = 0 to 51). There was a strong association between depression at three months and receiving benzodiazepines in the ICU (mean difference between groups = 6.73 points (95% CI: 1.42, 12.06), scale = 0 to 60). Use of inotropes or vasopressors was correlated with anxiety, and corticosteroids with better physical quality of life.

CONCLUSIONS

Strikingly high rates of psychological morbidity were found in this cohort of intensive care survivors. The study's key finding was that acute psychological reactions in the ICU were the strongest modifiable risk factors for developing mental illness in the future. The observation that use of different ICU drugs correlated with different psychological outcomes merits further investigation. These findings suggest that psychological interventions, along with pharmacological modifications, could help reduce poor outcomes, including PTSD, after intensive care.

Meanings of being critically ill in a sound-intensive ICU patient room - a phenomenological hermeneutical study

The aim of this study was to illuminate the meanings of being critically ill in a sound-intensive ICU patient room, as disclosed through patients’ narratives. Patient rooms in ICUs are filled with loud activity and studies have revealed sound levels comparable to those of a busy road above the patient’s head. There is a risk that the sound or noise is disturbing and at worst a major problem for the patient, but there is a lack of knowledge concerning the patients’ own experiences. Thirteen patients were asked to narrate their experiences of the sound environment in ICU patient rooms. The interviews were analyzed using a phenomenological- hermeneutical method inspired by the philosophy of Ricoeur. Six themes emerged from the analysis. Conclusion: The meanings of being a patient in a sound- intensive environment were interpreted as never knowing what to expect next regarding noise, but also of being situated in the middle of an uncontrollable barrage of noise, unable to take cover or disappear. This condition is not to be seen as static; for some patients there is movement and change over time. The meanings indicate that the unpredictable shifts between silence and disturbing sounds stress the critically ill patient and impede sleep and recovery. Our findings indicate the need to reduce disturbing and unexpected sounds and noise around critically ill patients in high-tech environments in order to facilitate wellbeing, sleep and recovery. Nurses have a vital role in developing such an environment.

Predictive value and validation of the NEECHAM Confusion Scale using DSM-IV criteria for delirium as gold standard

BACKGROUND

Delirium is common among older people in hospital and various instruments have been developed for detecting delirium. One of these, the NEECHAM Confusion Scale, is easy for nurses to administrate but needs to be tested further.

AIMS AND OBJECTIVES

The aim of the present study was to assess the validity and predictive value of the NEECHAM Confusion Scale.

METHODS

The study was conducted among 149 patients aged ≥ 65, who had undergone surgery for a hip fracture. The patients were observed daily using DSM-IV criteria for delirium. The NEECHAM Confusion Scale was performed upon admission and prior to discharge.

RESULTS

The incidence of DSM-IV related delirium was 24%. Patients who scored below 25 points on the NEECHAM scale had a 12 times higher risk of developing DSM-IV related delirium. During admission, the sensitivity of NEECHAM was zero because all patients with DSM-IV delirium were excluded, the specificity was 75%. On discharge, it was 100% and 91% respectively.

CONCLUSIONS

This study adds to the body of knowledge that NEECHAM discriminates for delirium. It is a valid and reliable screening instrument for predicting delirium. The instrument can be used for clinical practice to identify patients who are at risk of contracting delirium and when considering prevention measures.

Patients' participation in and evaluation of a follow-up program following intensive care

BACKGROUND

Patients' difficulties following critical illness and the willingness of intensive care units (ICU) to take an expanded responsibility during the recovery period have led to the development of different follow-up programs. The aim of this study was to explore and describe patients' participation in and evaluation of a follow-up program at a nurse-led clinic (NLC).

METHODS

Patients with a length of stay ≥72 h, discharged from the ICU, participated in a follow-up program based on three contacts, as a visit to the NLC, telephone contact, ward visit or as an indirect contact, during a 6-month period. A specially developed database recorded information regarding patients' participation and questionnaires were used to obtain patients' views of the follow-up program.

RESULTS

Of 96 study patients, 51% visited the NLC once or twice. These patients were younger (P<0.001) and had lower Acute Physiology and Chronic Health Evaluation II (P=0.017) compared with those who did not visit the clinic. The most common reason for not visiting the clinic was not enough strength, chiefly physical. In the evaluation, patients answered that they received advice and information, an opportunity to talk, increased knowledge and re-evaluated memories and experiences from the ICU stay. Patients appreciated the follow-up and expressed gratitude to the competent and obliging staff.

CONCLUSION

The current follow-up program, adjusted to individual patients' conditions and needs in terms of different types of contacts and continuity, was found to be of great value. Effects of the program other than the patient perspective are also relevant to evaluate.

Older adults' perceptions of feeling safe in an intensive care unit

AIM

This paper is a report of a study of older adults' perceptions of feeling safe in an intensive care unit.

BACKGROUND

Significant ageing of the world population is expected. Correspondingly, there is a growing global urgency for healthcare systems to prepare for the increased number of older adults who will require intensive care. Although patients have recounted situations in which feeling safe was essential to their experience, there is little empirical evidence about feeling safe for older adults in intensive care.

METHOD

In 2008, 10 older adults who suffered unexpected critical health events and who were admitted to intensive care units were recruited for this grounded theory study. Participants were interviewed after transferring to an intermediate care unit and again after discharge. They were asked to reflect upon and discuss their experiences of feeling safe in intensive care.

FINDINGS

Participants' actual and expected interaction with intensive care nurses was essential to their perceptions of feeling safe. Four main categories were identified as requisite to interaction with nurses: proximity, oversight, predictability and initiative. A substantive grounded theory of feeling safe for older adults in intensive care is presented.

CONCLUSION

Nurses must present themselves as accessible so patients perceive that they can initiate interaction with a qualified nurse. Patients must also see that nurses are monitoring them and believe that the nurses will help them if they experience a critical health event while in the intensive care unit.

The effect of nurse-facilitated family participation in the psychological care of the critically ill patient

AIM

This paper is a report of a Neuman systems model-guided study of the effects of nurse-facilitated family participation in psychological care on the extent of patient delirium and psychological recovery following critical illness.

BACKGROUND

Psychological disturbances resulting from critical illness have been well documented in international literature. Few studies have tested interventions designed to alleviate such disturbances.

METHODS

A comparative time series design was used. A total of 170 critically ill patients and families participated in the study - 83 in the control group and 87 in the intervention group. Data were collected during critical illness and subsequent recovery using the Therapeutic Intervention Scoring System-28, Intensive Care Delirium Screening Checklist and the Sickness Impact Profile. The study was carried out in Northern Ireland, data collection taking place from January 2004 to December 2005.

RESULTS/FINDINGS

Nurse-facilitated family participation in psychological care did not significantly reduce the incidence of delirium among patients in critical care, but patients receiving intervention demonstrated better psychological recovery and wellbeing than the control group at 4, 8 and 12 weeks after admission to critical care.

CONCLUSION

Nurse-facilitated family participation in the psychological care may strengthen the lines of defence and resistance against the stressors experienced by the patient during critical illness and improve psychological recovery.

Neurosurgery three times over: a psychiatrist's insider perspective

The author, a practicing psychiatrist, describes his own experience in becoming a neurosurgical patient, three times in quick succession, for a recurring subdural hematoma. In addition to a brief review of the literature, he observes his own experience, including reaction to the diagnosis and to the surgical, postsurgical, and intensive-care experience. Suggestions are made to neurosurgeons and their staff to help patients during this experience and in recovery, from the vantage point of a psychiatrist who specializes in dealing with psychological issues arising from illness.

An act of caring - patient diaries in Norwegian intensive care units

AIM

The aim of this study was to obtain more knowledge about the background, extent and implementation of diaries in Norwegian intensive care units (ICUs) providing mechanical ventilation to adult patients.

BACKGROUND

The growing understanding of long-term consequences of intensive care therapy has compelled nurses to introduce patient diaries to prevent problems after discharge from ICU. Research on this practice is limited.

DESIGN/METHOD

The study had a qualitative descriptive design, and was conducted by means of semi-structured telephone interviews with 30 participants, all experienced intensive care nurses. The strategy of analysis was a template organizing style.

FINDINGS

The findings show that 31 out of 70 ICUs offer patient diaries, and many units have a long history of diary writing. Most of the units have some kind of guidelines, and the study has shown that diaries serve dual purposes; one of caring and another of therapy. Although these two dimensions seemingly present a paradox from a theoretical point of view, a combination appears to be at work in clinical practice. This may be explained by a tendency in nursing to regard caring as superior to therapy. The writing frequency varies, and the units that reported high activity provided follow-up programs in addition to diary writing. Diary writing as a nursing intervention is threatened by a lack of funding.

Muslim women's experiences of suffering in Jordanian intensive care units: a narrative study

This paper explores Muslim women's experiences of suffering in Jordanian intensive care units. A narrative approach was employed to access women's stories of their critical illness. Sixteen women who had spent at least 48 hours in intensive care were recruited from two hospitals in a Jordanian city and took part in between one and three interviews over a six-month period. Women's accounts of suffering were pervaded with physical, social, spiritual and technological themes. Pain was a central strand in the women's accounts and was experienced often as severe, overwhelming and disturbing to their sleep. The sudden onset of illness, the unfamiliar ICU environment and feeling of uncertainty made it difficult for the women to interpret their experiences. Religious beliefs and cultural norms helped the women make sense of their suffering. Social support, especially from the family, was reported by the women to be essential: a lack of social support was seen as a symbol of death. This study emphasises the importance of looking at a patient who is critically ill as a whole person within the context of their cultural, spiritual and biographical milieu.

Patients' recovery after critical illness at early follow-up

AIM

To determine the quality of life, particularly physical function, of intensive care survivors during the early recovery process.

BACKGROUND

Survivors of critical illness face ongoing challenges after discharge from the intensive care unit and on returning home. Knowledge about health issues during early phases of recovery after hospital discharge is emerging, yet still limited.

DESIGN

Descriptive study where the former critically ill patients completed instruments on general health and quality of life (SF-36) in the first six months of recovery.

METHODS

Participants responded to the SF-36 questionnaire and questions about problems, one to six months after intensive care, either face-to-face or by telephone.

RESULTS

Thirty-nine participants had a mean age of 60 years; of them, 59% were men and had been in intensive care for 1-69 days (median = 5). Most participants (69%) rated their health as good or fair, but 54% rated general health as worse than a year ago. Mean quality of life scores for all scales ranged from 25-65.5%, with particularly low scores for Role-Physical (25) and Pain (45.1). Half the participants reported difficulty with mobility, sleep and concentration, and 72% that their responsibilities at home had changed. No relationships were found between SF-36 scores and admission diagnosis, gender, age or length of intensive care stay.

CONCLUSIONS

These survivors of critical illness and hospitalisation in an intensive care unit perceive their general health to be good despite experiencing significant physical limitations and disturbed sleep during recovery.

RELEVANCE TO CLINICAL PRACTICE

Knowledge of issues in these early phases of recovery and discussion and resolution of patient problems could normalise the experience for the patient and help to facilitate better quality of life.

Sedation practice in three Norwegian ICUs: a survey of intensive care nurses' perceptions of personal and unit practice

OBJECTIVES

To describe intensive care nurses' perceptions of unit and personal sedation practice in the context of nursing and medical treatment of adult intensive care patients sedated and ventilated for more than 24 hours.

METHODS

Self-administered questionnaire.

SETTING

Three general ICUs in three university hospitals in Norway.

RESULTS

Eighty-six questionnaires were returned (response rate 47%). Continuous infusions of fentanyl and midazolam were perceived as most common and nurses often gave both analgesics and sedatives prior to care. Daily interruption of sedation or analgesia-based sedation was not perceived as practice in the units. MAAS was most commonly used, whilst protocols or objective scoring systems were not. Documentation of sedation levels was fairly routine, whereas documentation of patient needs was not perceived as important. Collaboration with physicians was viewed as most important, whilst no significance was assigned to collaboration with relatives.

CONCLUSION

The study shows that a focus on analgesia-based sedation and continual control of the sedation level should be considered in order to decrease the risk of oversedation. Inclusion of relatives' opinions, increased collaboration between nurses and physicians, and implementation of sedation tools, may contribute to even better patient outcome and should be focus in further studies.

Surgical intensive care unit (ICU) delirium: a "psychosomatic" problem?

OBJECTIVE

Intensive Care Unit (ICU) delirium is a common complication after major surgery and related among other potential medical precipitants to either pre-existing cognitive impairment or the intensity and length of anesthesiology or the type of surgery. Nevertheless, in some rare situations, an organic etiology is not always found, which can be frustrating for the medical team. Some clinicians working in an intensive care unit have a reluctance to seek another hypothesis in the psychological field.

METHOD

To illustrate this, we report the case of a 59-year-old woman who developed a massive delirium during her intensive care unit stay after being operated on for a left retroperitoneal sarcoma. Interestingly, she had had no previous cognitive disorders and a somatic explanation for her psychiatric disorder could not been found. Just before the surgery, she was grieving the recent loss of a colleague of the same age, and also a close friend, and therefore had a death anxiety.

RESULTS

With this case report, we would like to point out the importance of psychological factors that might precipitate delirium in a predominately somatic environment such as an intensive care unit.

SIGNIFICANCE OF RESULTS

ICU delirium can sometimes be considered as a "psychosomatic" problem with either a stress response syndrome after surgery or a defense mechanism against death anxiety. Clinicians should be aware of the possibility of such psychological factors even if they always must first rule out potential somatic causes for delirium and encourage thorough investigation and treatment of these medical causes. A collaboration with the psycho-oncologist is recommended to better manage this "psychosomatic" problem.

More than nothing: the lived experience of tracheostomy while acutely ill

While the physical sensations surrounding tracheostomy tube insertion have been reported within nursing and allied healthcare literature, the lived experience of these sensations is poorly described. This appears relevant given the imminent results of the Tracman study (2008). A purposive sample of three participants who had tracheostomy tubes previously within a critical care area or still in situ were recruited. They described their experiences in a face-to-face semi-structured interview that were audio taped. The interviews were transcribed verbatim and analysed using Giorgi's 5 concrete steps of the human scientific phenomenological method (1997). Findings revealed themes that drew attention to the fundamental aspects of the experience. These were: Practical recommendations draw attention to the organisational support required for staff expected to care for these patients in the ward environment. This involves the introduction of evidence based guidelines and competency based care to promote the acquisition of skills required to perform those essential tasks such as suction and stoma care to a high standard. Protected, formalised skills based teaching is seen as fundamental in this process. Patients' felt confident in nursing staff that were able to demonstrate proficiency with such tasks and this is seen as crucial when one considers that the tracheostomy tube is a new experience for patients.

The PRaCTICaL study of nurse led, intensive care follow-up programmes for improving long term outcomes from critical illness: a pragmatic randomised controlled trial

OBJECTIVES

To test the hypothesis that nurse led follow-up programmes are effective and cost effective in improving quality of life after discharge from intensive care.

DESIGN

A pragmatic, non-blinded, multicentre, randomised controlled trial.

SETTING

Three UK hospitals (two teaching hospitals and one district general hospital).

PARTICIPANTS

286 patients aged >or=18 years were recruited after discharge from intensive care between September 2006 and October 2007.

INTERVENTION

Nurse led intensive care follow-up programmes versus standard care. Main outcome measure(s) Health related quality of life (measured with the SF-36 questionnaire) at 12 months after randomisation. A cost effectiveness analysis was also performed.

RESULTS

286 patients were recruited and 192 completed one year follow-up. At 12 months, there was no evidence of a difference in the SF-36 physical component score (mean 42.0 (SD 10.6) v 40.8 (SD 11.9), effect size 1.1 (95% CI -1.9 to 4.2), P=0.46) or the SF-36 mental component score (effect size 0.4 (-3.0 to 3.7), P=0.83). There were no statistically significant differences in secondary outcomes or subgroup analyses. Follow-up programmes were significantly more costly than standard care and are unlikely to be considered cost effective.

CONCLUSIONS

A nurse led intensive care follow-up programme showed no evidence of being effective or cost effective in improving patients' quality of life in the year after discharge from intensive care. Further work should focus on the roles of early physical rehabilitation, delirium, cognitive dysfunction, and relatives in recovery from critical illness. Intensive care units should review their follow-up programmes in light of these results.

The meaning of family members' presence during intensive care stay: a qualitative study

The aim of this study was to investigate what the presence of family members meant to patients in intensive care units. The study employed a qualitative approach with semi-structured interviews and qualitative content analysis. Eleven intensive care patients were interviewed at a university hospital in Norway. The results of the study indicated that the patients desired some limitation of visitors' presence and preferred visits only from those who were closest in daily life. Visits had a variety of functions for intensive care patients, including promoting support for patients and families. However, visits also caused stress for patients and worries about creating stress for family members. The patients' requirements for information differed. The findings suggest that information to the families is important for the patients need for reality orientation. Visits in intensive care units and information to the families have mutual importance for the patients and their families. The study supports prior claims that flexible visiting routines are challenging for ICU nurses. A dialogue with the families is recommended in order to find a balance between the social support and the stress caused by visits. This puts the families in a better position to give support to the patients during recovery.

Outcome after injury: memories, health-related quality of life, anxiety, and symptoms of depression after intensive care

BACKGROUND

To examine the relationship between delusional memories from the Intensive Care Unit (ICU) stay, health related quality of life (HRQoL), anxiety, and symptoms of depression in patients with physical trauma, 6 months to 18 months after their ICU stay.

METHODS

Multicenter study in five combined medical and surgical ICUs (n = 239). A questionnaire comprising the Medical outcome Short Form 36, the Hospital Anxiety and Depression scale, and the Intensive Care Unit Memory tool was sent to the patients with trauma 6 months to 18 months after their discharge from the ICU. Clinical data were drawn from patient records in retrospect. A matched reference sample (n = 159) was randomly drawn from the Swedish Short Form 36 norm database (n = 8,930).

RESULTS

Patients with trauma had significantly lower HRQoL than the reference sample. One or more delusional memories such as hallucinations, nightmares, dreams, or sensations of people trying to hurt them in the ICU were experienced by 26%. These patients were significantly younger, had a longer ICU stay, relied more on mechanical ventilation, and had higher Injury Severity Score and Sequential Organ Failure Assessment scores. They also reported a significantly poorer HRQoL and a higher probability of experiencing anxiety (51% vs. 29%) and symptoms of depression (48% vs. 26%) compared with patients without such memories.

CONCLUSIONS

Our results highlight the importance of treating the delusional memories experienced by ICU patients with a trauma diagnosis as a postinjury factor with a potential to create anxiety and symptoms of depression and which may affect HRQoL after discharge.
