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

Patient recall of intensive care delirium: A qualitative investigation

BACKGROUND

Many patients in the Intensive Care Unit (ICU) experience delirium. Understanding the patient perspective of delirium is important to improve care and reduce suffering. The aim of our study was to investigate the subjective patient experience of delirium, delirium-related distress, and delirium management in ICU.

METHODS

Our study had a qualitative multicenter design applying individual interviews and thematic analysis. Participants were critically ill adult patients that were determined delirium positive according to validated delirium screening tools during ICU admission. The interviews were conducted after ICU discharge when patients were delirium-free as assessed by the "Rapid clinical test for delirium" (4AT) and able to participate in an interview.

RESULTS

We interviewed 30 patients choosing the main themes deductively: Delirium experience; Delirium related distress; and Delirium management. Despite variations in recollection detail, ICU survivors consistently reported delirium-related distress during and after their ICU stay, manifesting as temporal confusion, misinterpretations, and a sense of distrust towards ICU staff. Delusions were characterized by a blend of factual and fictional elements. Impaired short-term memory hindered communication and intensified feelings of isolation, neglect, and loss of control.

CONCLUSION

The ICU survivors in our study recalled delirium as an unpleasant and frightening experience, often leading to delirium-related distress during and after their ICU stay, indicating the necessity for enhanced assessment and treatment.

Bringing Delirium to Light: Impact of CAM-ICU Tool to Improve Care Coordination

BACKGROUND

Delirium is a serious complication in patients in the critical care unit (CCU) that may lead to prolonged hospitalization if left undetected. The CCU at our hospital does not have a framework for determining delirium that could affect patient outcomes and discharge planning.

PRIMARY PRACTICE SETTING

CCU in a community hospital.

METHOD

A posttest-only design was used for this study. We established a framework for the early assessment of delirium, educated and trained nurses to detect delirium, collaborated with the informatics department, intensivist, nursing, respiratory therapy and worked with case management to deploy the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU). We used a one-tailed independent t test to determine the impact of CAM-ICU on length of stay (LOS). Cross-tabulation and chi-square tests were used to examine the impact of CAM-ICU tool on home care utilization between the intervention and comparison groups.

RESULTS

There was a 3.12% reduction in LOS after implementing the CAM-ICU tool. Also, a reduction in home care service utilization demonstrated statistical significance ( p = .001) between the intervention group (62.5%; n = 177) and the comparison group (37.5%; n = 106).

IMPLICATIONS FOR CASE MANAGEMENT PRACTICE

Case managers are essential in improving care transitions. Case managers need to become competent in understanding the implications of the CAM-ICU tool because of their relevant role in the multidisciplinary rounds as advocates to improve care transitions across the continuum of care. Case managers need to have an understanding on how to escalate when changes in the Richmond Agitation-Sedation Scale scores occur during the multidisciplinary rounds because it can affect care coordination throughout the hospital.

CONCLUSIONS

Implementing the CAM-ICU decreased LOS, and reduced health care utilization. The early identification of patients with delirium can affect the outcomes of critically ill patients and entails multidisciplinary collaboration.

Requesting That Delirium Achieve Parity With Acute Encephalopathy in the MS-DRG System

Since 2007, the Medicare Severity Diagnosis Related Groups classification system has favored billing codes for acute encephalopathy over delirium codes in determining hospital reimbursement and several quality-of-care value metrics, despite broad overlap between these sets of diagnostic codes. Toxic and metabolic encephalopathy codes are designated as major complication or comorbidity, whereas causally specified delirium codes are designated as complication or comorbidity and thus associated with a lower reimbursement and lesser impact on value metrics. The authors led a submission to the U.S. Centers for Medicare and Medicaid Services requesting that causally specified delirium be designated major complication or comorbidity alongside toxic and metabolic encephalopathy. Delirium warrants reclassification because it satisfies U.S. Centers for Medicare and Medicaid Services' guiding principles for re-evaluating Medicare Severity Diagnosis Related Group severity levels. Delirium: (1) has a bidirectional relationship with the permanent condition of dementia (major neurocognitive disorder per DSM-5-TR), (2) indexes vulnerability across populations, (3) impacts healthcare systems across levels of care, (4) complicates postoperative recovery, (5) consigns patients to higher levels of care, (6) impedes patient engagement in care, (7) has several recent treatment guidelines, (8) often indicates neuronal/brain injury, and (9) represents a common expression of terminal illness. The proposal's impact was explored using the 2019 National Inpatient Sample, which suggested that increasing delirium's complexity designation would lead to an upcoding of less than 1% of eligible discharges. Parity for delirium is essential to enhancing awareness of delirium's clinical and economic costs. Appreciating delirium's impact would encourage delirium prevention and screening efforts, thereby mitigating its dire outcomes for patients, families, and healthcare systems.

The phenotype of delirium based on a close reading of diagnostic criteria

OBJECTIVE

Although delirium is well known to acute care clinicians, the features required for its diagnosis and how to understand and operationalize them remain sticking points in the field. To clarify the delirium phenotype, we present a close reading of past and current sets of delirium diagnostic criteria.

METHODS

We first differentiate the delirium syndrome (i.e., features evaluated at bedside) from additional criteria required for diagnosis. Next, we align related features across diagnostic systems and examine them in context to determine intent. Where criteria are ambiguous, we review common delirium instruments to illustrate how they have been interpreted.

RESULTS

An acute disturbance in attention is universally attested across diagnostic systems. A second core feature denotes confusion and has been included across systems as disturbance in awareness, impaired consciousness, and thought disorganization. This feature may be better understood as a disturbance in thought clarity and operationalized in terms of neuropsychological domains thereby clearly linking it to global neurocognitive disturbance. Altered level of activity describes a third core feature, including motor and sleep/wake cycle disturbances. Excluding stupor (wherein mental content cannot be assessed due to reduced arousal) from delirium, as in DSM-5-TR, is appropriate for a psychiatric diagnosis, but the brain injury exclusion in ICD-11 is unjustified.

CONCLUSIONS

The delirium phenotype involves a disturbance in attention, qualitative thought clarity, and quantitative activity level, including in relation to expected sleep/wake cycles. Future diagnostic systems should include a severity threshold and specify that delirium diagnosis refers to a 24-h period.

Associations between delirium and SARS-CoV-2 pandemic visitor restrictions among hospitalized patients

OBJECTIVES

Delirium is associated with increased morbidity and mortality, but environmental and behavioral factors may decrease the risk of developing delirium and thus must be considered. To investigate trends in delirium prevalence and examine associations of visitor restrictions with delirium diagnoses among all patients hospitalized during and prior to the novel coronavirus SARS-CoV-2 (COVID-19) pandemic.

STUDY DESIGN

Retrospective epidemiological assessment.

METHODS

The medical records of all patients (n = 33,141) hospitalized within a three-hospital academic medical center system in a large Midwestern metropolitan area from March 20, 2019, through March 19, 2021, were analyzed.

RESULTS

The overall prevalence of delirium during COVID-19 was 11.26% (confidence interval [CI]: 10.79%, 11.73%) compared to 9.28% (CI: 8.82%, 9.73%) before COVID-19. From our adjusted logistic regression analyses, we observed that the odds of delirium among non-isolated patients were significantly higher during COVID-19 visitor restrictions (adjusted odds ratio [aOR]: 1.354; 95% CI: 1.233, 1.488; P < 0.0001) than before. The odds of delirium among isolated patients were not significantly higher during COVID-19 visitor restrictions (aOR: 1.145; 95% CI: 0.974, 1.346; P = 0.1006) than before.

CONCLUSIONS

Medically isolated patients remained at high risk of developing delirium both prior to and during COVID-19 era visitor restrictions. However, non-medically isolated patients had a significantly increased risk of delirium during the social isolation of visitor restrictions compared to prior to visitor restrictions.

Struggling to return to everyday life-The experiences of quality of life 1 year after delirium in the intensive care unit

BACKGROUND

Many critically ill patients report a change in their health-related quality of life after intensive care unit (ICU) discharge. Patients who experience delirium during their ICU stay are perceived as a fragile group of ICU survivors, and the 'quality of life' phenomenon needs to be studied among these patients.

AIM

To explore everyday life experiences of critically ill patients with delirium during the ICU stay, from ICU discharge until 1-year follow-up, focusing on their health-related quality of life and cognitive function.

STUDY DESIGN

We used a descriptive qualitative research design and interviewed patients 1 year after ICU admission. The participants were recruited from a pre-planned one-year follow-up study of 'Agents Intervening against Delirium for patients in the Intensive Care Unit trial'. Data were analysed using Framework Analysis Method and content analysis.

RESULTS

Nine women and eight men participated and reported a struggle when returning to everyday life or adapting to a new normality from hospital discharge to 1 year later. None of the participants had been aware of the challenges they would face after hospital discharge. They described a need for more information about these challenges to themselves and about primary care to better understand their situation and the struggles they experience during recovery. One overall theme emerged from the analysis 'From enduring to adapting' with three subthemes: 'Struggling to regain a functional life', 'Struggling to regain normal cognition' and 'Distressing manifestations from the ICU'.

CONCLUSIONS

To improve recovery and the quality of rehabilitation for critically ill patients suffering from delirium, it is essential to understand the phenomenon of ICU survivorship and what this fragile group of patients is going through. It is necessary to bridge the gap between secondary and primary care so patients can receive optimal training and support when needed.

RELEVANCE TO CLINICAL PRACTICE

Bridging the gap between primary and secondary healthcare services is urgently needed to improve rehabilitation for ICU survivors after critical illness.

Family functioning of families experiencing intensive care and the specific impact of the COVID-19 pandemic: A grounded theory study

OBJECTIVES

In order to provide a deeper understanding of family functioning, the aim of this study was to identify, describe and conceptualise the family functioning of families where a formerly critically ill family member had stayed at the intensive care unit, with the impact of a pandemic.

RESEARCH METHODOLOGY/DESIGN

The study has a grounded theory design including interviews with eight families.

SETTING

Former adult intensive care patients cared for Covid-19 infection and their family. Eight patients and twelve family members from three different intensive care units.

MAIN OUTCOME MEASURES

The results presented are grounded in data and identified in the core category "Existential issues" and the categories "Value considerateness; Anxiety and insecurity in life; Insight into the unpredictability of life."

FINDINGS

The core category could be found in all data and its relationship and impact on the categories and each other. The core is a theoretical construction, whereas the family functioning of families where a formerly critically ill family member had stayed at the intensive care unit was identified, described, and conceptualised. Being able to talk repeatedly about existential issues and the anxiety and insecurity in life, with people that have similar experiences helps the patient and their family to consider and gain insight into the unpredictability of life, and thereby better cope with changes in life.

CONCLUSION

There is awareness about the love that exists within the family. A willing to supporting each other in the family even if the critical illness made the family anxious and afraid.

IMPLICATIONS FOR CLINICAL PRACTICE

Even if the pandemic Covid-19 led to restrictions inhibiting family focused nursing, it is important to confirm the family as a part of the caring of the ICU patient. The patients are not alone, their family are fighting together for the future.

Delirium-related psychiatric and neurocognitive impairment and the association with post-intensive care syndrome-A narrative review

INTRODUCTION

Delirium is common among patients admitted to the intensive care unit (ICU) and its impact on the neurocognitive and psychiatric state of survivors is of great interest. These new-onset or worsening conditions, together with physical alterations, are called post-intensive care syndrome (PICS). Our aim is to update on the latest screening and follow-up options for psychological and cognitive sequelae of PICS.

METHOD

This narrative review discusses the occurrence of delirium in ICU settings and the relatively new concept of PICS. Psychiatric and neurocognitive morbidities that may occur in survivors of critical illness following delirium are addressed. Future perspectives for practice and research are discussed.

RESULTS

There is no "gold standard" for diagnosing delirium in the ICU, but two extensively validated tools, the confusion assessment method for the ICU and the intensive care delirium screening checklist, are often used. PICS complaints are frequent in ICU survivors who have suffered delirium and have been recognized as an important public health and socio-economic problem worldwide. Depression, anxiety, post-traumatic stress disorder, and long-term cognitive impairment are recurrently exhibited. Screening tools for these deficits are discussed, as well as the suggestion of early assessment after discharge and at 3 and 12 months.

CONCLUSIONS

Delirium is a complex but common phenomenon in the ICU and a risk factor for PICS. Its diagnosis is challenging with potential long-term adverse outcomes, including psychiatric and cognitive difficulties. The implementation of screening and follow-up protocols for PICS sequelae is warranted to ensure early detection and appropriate management.

Examining Subjective Psychological Experiences of Postoperative Delirium in Older Cardiac Surgery Patients

BACKGROUND

Postoperative delirium (POD) is an acute syndrome including inattention and impaired cognition that affects approximately 42% of older cardiac surgical patients. POD is linked to adverse outcomes including morbidity, mortality, and further cognitive decline. Less is known about the subjective psychological experience of POD and its ongoing impact on well-being.

METHODS

We performed a qualitative analysis of the long-term psychological sequelae of older adults who experience POD after cardiac surgery. We sampled 30 patients aged 60 years and older who experienced at least 2 episodes of POD during a prior hospital admission. We administered semistructured interviews with participants via telephone 3 to 5 years postoperatively. Interviews were transcribed and thematically analyzed. Data were interpreted in accordance with the naturalist paradigm.

RESULTS

Three overarching themes emerged in our qualitative analysis. The first reflected the multifaceted presentation of POD, including distortion of time and reality; feelings of isolation; and a loss of self, identity, and control. The second theme reflected the psychological challenges associated with functional decline after surgery. Common examples of functional decline included cognitive difficulties, excessive fatigue, and a perceived loss of independence. The final theme captured the emotional sequelae of acute illness, which included low mood, reduced motivation, and social comparisons.

CONCLUSIONS

Our findings emphasize the multidimensional experience of POD and long-term effects on psychological wellbeing. Our research highlights the beneficial role multidisciplinary clinicians play in managing POD including strategies that may be embedded into clinical practice and helps anesthesiologists understand why patients who have experienced POD in the past may present with specific concerns should they require subsequent surgery.

Impact of a sensory stimulation program conducted by family members on the consciousness and pain levels of ICU patients: A mixed method study

Background

The results of several studies show the different effects of a balanced sensory stimulation program (SSP) on patients with brain injury admitted to the intensive care unit (ICU), but these effects have been less studied based on mixed and comprehensive methods.

Method

This mixed-method study involved 66 patients with brain injury admitted to the ICU who were allocated into intervention (n = 33) and control (n = 33) groups using random stratified sampling. Patients in the intervention group received a sensory stimulation program from family members for 1 h daily during ICU hospitalization, while the control group received only routine care. Patients' level of consciousness and pain intensity were measured immediately before and after the intervention using Glasgow Coma Scale (GCS) and Behavioral Pain Scale (BPS), respectively. In-depth unstructured interviews were conducted with the patients in the intervention group 3 months after discharge from the ICU. These interviews were analyzed following Graneheim and Lundman (2004) conventional content analysis method.

Results

A significant difference was found between the study groups in terms of the mean difference of GCS (P =0.001) and BPS score (P = 0.001) before and after intervention. Patients in the intervention group had a higher mean GCS and a lower mean BPS than did patients in the control group. The main themes extracted from the qualitative analysis confirmed the results obtained from the quantitative phase of the study.

Conclusion

The combination of the quantitative and qualitative findings suggested that amidst the many hardships and sufferings brain injury patients go through in the ICU, a sensory stimulation program offered by family members may have many benefits such as increased level of consciousness and reduced pain for these patients. Therefore, it is necessary to formulate a framework for this program and provide the needed facilities in order to benefit more from the capacity of such programs for ICU patients.

Peripheral interleukin-6-associated microglial QUIN elevation in basolateral amygdala contributed to cognitive dysfunction in a mouse model of postoperative delirium

Background

Developing effective approaches for postoperative delirium has been hampered due to the lack of a pathophysiologically similar animal model to offer insights into the pathogenesis. The study, therefore, aimed to develop a delirium-like mouse model and explore the underlying mechanism.

Methods

The three cycles of 10-min clamp following 5-min reopening of the superior mesenteric artery (SMA) were performed in adult male C57BL/6 mice to induce a delirium-like phenotype. Composite Z score calculated based on the results of Open Field, Y Maze and Buried Food Tests was employed to assess the delirium phenotype in mice. Microglia activities were monitored by immunofluorescence staining and comprehensive morphological analysis. Systemic administration of minocycline (MINO), IL-6 antibody or IL-6 neutralizing antibody, was applied to manipulate microglia. The expressions of Indoleamine 2,3-dioxygenase-1 (IDO-1) and quinolinic acid (QUIN) were examined by RT-PCR and High-Performance Liquid Chromatography/Mass Spectrometry, respectively. Cytokines were measured using fluorescence activated cell sorting method.

Results

The repeated ischemia/reperfusion (I/R) surgery caused significant anxiety (P < 0.05) and cognition decline in working memory and orientation (P < 0.05) in mice at postoperative 24 h. The composite Z score, indicating an overall disturbance of brain function, fluctuated over 24 h after I/R surgery (P < 0.001). Immunofluorescent staining showed that the percentage of microglia in the basolateral amygdala (BLA) (P < 0.05) was reactivated after I/R surgery and was negatively correlated with dwell time at Y maze (R = −0.759, P = 0.035). Inhibiting microglia activities by MINO reduced QUIN productions (P < 0.01) that improved cognitive deficits (P < 0.05). The peripheral IL-6 might cause IL-6 elevation in the BLA. Systemic administration of IL-6 antibodies suppressed I/R-induced IL-6 elevations (P < 0.05), microglial reactivations (P < 0.05), IDO-1 expressions (P < 0.01), and neuroactive metabolite QUIN productions (P < 0.05) in the BLA, resulting in a recovery of cognitive deficits (P < 0.05). Injection of IL-6 exerted opposite effects.

Conclusion

The repeated intestinal I/R surgery-induced mouse model is a simple and reproducible one of postoperative delirium. Peripheral IL-6-associated microglial QUIN elevations in the BLA contributed to cognitive dysfunction in the model of postoperative delirium.

Effect of Intensive Psychological Nursing Intervention on HAMD and SF-36 Scores in Patients with Severe Liver Cancer in ICU

The aim of the study was to explore the effect of intensive psychological nursing intervention on HAMD and SF-36 scores in patients with severe liver cancer in intensive care unit (ICU). 134 critically ill patients with liver cancer in ICU who underwent resection of primary liver cancer from July 2019 to November 2021 were selected. The patients were randomly divided into control group and study group. The patients in the control group received routine nursing. The patients in the study group received intensive psychological nursing intervention on the basis of routine nursing. Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), and the MOS 36-item short-form health survey (SF-36) scores before and after nursing were compared between the two groups. The satisfaction of the two groups of patients with nursing was counted. The HAMA, HAMD, and SF-36 scores of patients receiving intensive psychological nursing intervention were significantly better than those receiving routine nursing. The nursing satisfaction of patients receiving intensive psychological nursing intervention was significantly higher than that of patients receiving routine nursing. Intensive psychological nursing intervention for patients with severe liver cancer in ICU can significantly reduce HAMD, improve SF-36 score, and patient nursing satisfaction. It is worthy of wide clinical promotion.

Delirium in intensive care: violence, loss and humanity

Delirium in intensive care is an altered state that can bring with it persecutory paranoias, and sometimes expressions of violence on the part of the patient; it can be deeply disturbing for the person experiencing it as well as for those around them. Although the impacts of delirium on patients' recovery and long-term mental health are well documented, qualitative research in this area remains rare. This article is derived from a narrative and musical study of the experience of delirium in hospital, undertaken better to understand the perspectives of people who have experienced delirium, as well as the healthcare professionals and family members who care for them. Data were collected in South Africa between 2015 and 2017. The study took the form of interviews and focus groups with a total of 15 participants, as well as periods of observation and audio recording in a hospital intensive care unit. Thematic and narrative analysis of the data were carried out alongside the composition of new music incorporating audio recordings from the study. Analysis suggested three key themes emerging from the data. First, the violence experienced and expressed by patients, both within delirious hallucination and in observable reality. Second, the interconnected losses undergone by patients in spaces of intensive care. Third, healthcare professionals' attempts to bring greater humanity into the potentially dehumanising space of intensive care. The results and discussion point to possible relationships between delirium and the working cultures and physical environment of intensive care, and may reinforce the need for sensitive and committed communication between healthcare professionals and patients.

Caring for patients displaying agitated behaviours in the intensive care unit - A mixed-methods systematic review

BACKGROUND

Patient agitation is common in the intensive care unit (ICU), with consequences for both patients and health professionals if not managed effectively. Research indicates that current practices may not be optimal. A comprehensive review of the evidence exploring nurses' experiences of caring for these patients is required to fully understand how nurses can be supported to take on this important role.

OBJECTIVES

The aim of this study was to identify and synthesise qualitative and quantitative evidence of nurses' experiences of caring for patients displaying agitated behaviours in the adult ICU.

METHODS

A mixed-methods systematic review was conducted. MEDLINE, CINAHL, PsycINFO, Web of Science, Emcare, Scopus, ProQuest, and Cochrane Library were searched from database inception to July 2020 for qualitative, quantitative, and mixed-methods studies. Peer-reviewed, primary research articles and theses were considered for inclusion. A convergent integrated design, described by Joanna Briggs Institute, was utilised transforming all data into qualitative findings before categorising and synthesising to form the final integrated findings. The review protocol was registered with PROSPERO CRD42020191715.

RESULTS

Eleven studies were included in the review. Integrated findings include (i) the strain of caring for patients displaying agitated behaviours; (ii) attitudes of nurses; (iii) uncertainty around assessment and management of agitated behaviour; and (iv) lack of effective collaboration and communication with medical colleagues.

CONCLUSIONS

This review describes the challenges and complexities nurses experience when caring for patients displaying agitated behaviours in the ICU. Findings indicate that nurses lack guidelines together with practical and emotional support to fulfil their role. Such initiatives are likely to improve both patient and nurse outcomes.

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.

Virtual reality stimulation to reduce the incidence of delirium in critically ill patients: study protocol for a randomized clinical trial

BACKGROUND

Delirium has been long considered as a major contributor to cognitive impairments and increased mortality following a critical illness. Pharmacologic and non-pharmacologic strategies are used against delirium in the intensive care unit (ICU), despite these strategies remaining controversial. Previous studies have shown the feasibility of using virtual reality within the ICU setting, and we propose to use this technology to investigate the effect of immersive virtual reality stimulation on the incidence of delirium in the ICU. Moreover, we propose to use motion sensors to determine if patient movement patterns can lead to early prediction of delirium onset.

METHODS

This study is conducted as a randomized clinical trial. A total of 920 critically ill patients in the ICU will participate. The control group will receive standard ICU care, whereas the intervention group will, in addition to the standard ICU care, receive relaxing 360-degree immersive virtual reality content played inside a head-mounted display with noise-cancelling headphones, three times a day. The first 100 patients, regardless of their group, will additionally have their movement patterns recorded using wearable and ambient sensors. Follow-up measurements will take place 6 months after discharge from the ICU.

DISCUSSION

Delirium is widely present within the ICU setting but lacks validated prevention and treatment strategies. By providing patients with virtual reality stimulation presented inside a head-mounted display and noise-cancelling headphones, participants may be isolated from disturbances on an ICU. It is believed that by doing so, the incidence of delirium will be decrease among these patients. Moreover, identifying movement patterns associated with delirium would allow for early detection and intervention, which may further improve long-term negative outcomes associated with delirium during critical care.

Tools for assessment of acute psychological distress in critical illness: A scoping review

OBJECTIVES

Patients' experience of psychological distress in the intensive care unit (ICU) is associated with adverse effects, reduced satisfaction, and delayed physical and psychological recovery. There are no specific guidelines for the assessment and management of acute psychological distress during hospitalisation in the ICU. We reviewed existing tools for the assessment of acute psychological distress in ICU patients, examined evidence on their metric properties, and identified potential gaps and methodological considerations.

METHOD

A scoping review based on literature searches (Cumulative Index to Nursing and Allied Health Literature, Medical Literature Analysis and Retrieval System Online, Excerpta Medica Database, PsycINFO, Scopus, Health and Psychosocial Instruments, Dissertations and Theses Global, and Google Scholar) and predefined eligibility criteria was conducted as per current scoping review guidelines.

FINDINGS

Overall, 14 assessment tools were identified having been developed in diverse ICU settings. The identified tools assess mainly anxiety and depressive symptoms and ICU stressors, and investigators have reported various validity and reliability metrics. It was unclear whether available tools can be used in specific groups, such as noncommunicative patients and patients with delirium, brain trauma, stroke, sedation, and cognitive impairments.

CONCLUSION

Available tools have methodological limitations worth considering in future investigations. Given the high prevalence of psychiatric morbidity in ICU survivors, rigorously exploring the metric integrity of available tools used for anxiety, depressive, and psychological distress symptom assessment in the vulnerable ICU population is a practice and research priority.

RELEVANCE TO CLINICAL PRACTICE

These results have implications for the selection and implementation of psychological distress assessment methods as a means for promoting meaningful patient-centred clinical outcomes and humanising ICU care experiences.

First Person Account COVID 19 Delirium in a Doctor: When Death Stalks the Mind

Previous studies reported that 20-30% of COVID-19 patients will develop delirium during the hospitalization, achieving 70% in cases of severe illness. The risks factors and the consequences of delirium are well-documented in the literature; however, little is known about the personal experience of delirium. Delirium burden is common and tends to be distressing even after the delirium episode has resolved. Taking this in mind, the present work provides a first-person account of a doctor who acquired Covid-19 and developed bilateral pneumonia and had delirium and a complicate course of illness. During the course of his delirium, the patient recalled experiences of reality and unreality, complete disorientation, lack of control, strong emotions, and intense fear of dying which was significantly distressing. We anticipate that delirium burden will be common on these patients and family members and clinicians should be aware of this phenomenon in order to evaluate the neuropsychiatric consequences of this condition.

Use of Diaries in Intensive Care Unit Delirium Patients: German Nursing Perspectives

Diaries are written for patients in intensive care units by staff and relatives, especially when patients experience a disorder of their consciousness, such as delirium. Diary entries are written in common language, describing the situation of the patient. The diary can be read by the patient and the family and support the coping and understanding of what happened. It can function as a tool for supporting communication about different experiences and views of critical illness.

A quality improvement project to improve the identification and management of delirium

BACKGROUND

Efforts to reduce delirium burden through screening, identification, and prevention is considered one of the major public health priorities of the last decade. In 2017, an audit of delirium screening in our unit revealed suboptimum assessment of our patients, with compliance with the Confusion Assessment Method for the ICU (CAM-ICU) assessments highly variable and ad hoc, and sometimes not at all. A separate sedation audit also revealed that our sedation practices did not align with current critical care guidelines emphasizing light sedation strategies.

AIM

The aim of this project was to develop resources to educate the unit on delirium, improve the management of sedation with a sedation algorithm, formalize the elements of delirium prevention and care into a delirium pathway, and improve the compliance with delirium screening.

METHODS

We developed a delirium clinical pathway and sedation algorithm, a delirium resource book, and an online educational module on the district health board (DHB) intranet. We provided extensive teaching of all these resources over delirium month. We used pre- and post-auditing of sedation practices and delirium screening compliance to inform the success of this project.

RESULTS

Of the 140 members of staff, 85% (n = 120) received delirium education. In 2018/2019, 84% of 145 patient charts reached the unit standard of four to six hourly CAM-ICU assessments compared with 45% in 2017. The sedation audit revealed a slight improvement in the trend towards lighter sedation, with Richmond Agitation Sedation Scoring (RASS) scores reflecting light sedation, increasing from a mean of 31% in 2017 to 41% in 2019 from 41 patient charts.

CONCLUSIONS

This project provides a useful framework to enable future quality improvement work around delirium and sedation management. The clinical pathway and sedation algorithm have been a useful tool to introduce to the unit as a way of formalizing the elements of delirium care and assessment.

Delirium in intensive care: A stepped-wedge cluster randomised controlled trial for a nurse-led intervention to reduce the incidence and duration of delirium among adults admitted to the intensive care unit (protocol)

BACKGROUND

Delirium is an acute disorder of attention and cognition with the highest rates among adults receiving intensive care. An acute episode of delirium is associated with morbidity and mortality, as well as a significant psychological sequela. Importantly, an increasing body of evidence supports the benefit of nonpharmacological, nurse-led interventions to reduce the incidence and duration of delirium among adults cared for in the intensive care unit (ICU).

OBJECTIVES

This study will evaluate the impact of a nursing-led delirium prevention protocol that is aimed at reducing the incidence and duration of delirium among adults admitted to the ICU. The delirium prevention nursing protocol specifically targets risk factors for delirium.

STUDY PLAN

A stepped-wedge cluster randomised controlled trial approach will be used to assess the effectiveness of the nurse-led intervention, in four adult ICUs across the South Western Sydney Local Health District (SWS-LHD), over a 12-month period. The primary outcomes of interest are (i) the incidence of delirium before and after the implementation of the nurse-led intervention and (ii) the number of delirium-free days during an ICU stay, before and after the implementation of the nurse-led intervention.
