Quality of life outcomes after intensive care. Comparison with a community group

A randomized clinical trial to evaluate the effect of post-intensive care multidisciplinary consultations on mortality and the quality of life at 1 year

PURPOSE

Critical illness is associated with long-term increased mortality and impaired quality of life (QoL). We assessed whether multidisciplinary consultations would improve outcome at 12 months (M12) after intensive care unit (ICU) discharge.

METHODS

We performed an open, multicenter, parallel-group, randomized clinical trial. Eligible are patients discharged alive from ICU in 11 French hospitals between 2012 and 2018. The intervention group had a multidisciplinary face-to-face consultation involving an intensivist, a psychologist, and a social worker at ICU discharge and then at M3 and M6 (optional). The control group had standard post-ICU follow-up. A consultation was scheduled at M12 for all patients. The QoL was assessed using the EuroQol-5 Dimensions-5 Level (Euro-QoL-5D-5L) which includes five dimensions (mobility, self-care, usual activities, pain, and anxiety/depression), each ranging from 1 to 5 (1: no, 2: slight, 3: moderate, 4: severe, and 5: extreme problems). The primary endpoint was poor clinical outcome defined as death or severe-to-extreme impairment of at least one EuroQoL-5D-5L dimension at M12. The information was collected by a blinded investigator by phone. Secondary outcomes were functional, psychological, and cognitive status at M12 consultation.

RESULTS

540 patients were included (standard, n = 272; multidisciplinary, n = 268). The risk for a poor outcome was significantly greater in the multidisciplinary group than in the standard group [adjusted odds ratio 1.49 (95% confidence interval, (1.04-2.13)]. Seventy-two (13.3%) patients died at M12 (standard, n = 32; multidisciplinary, n = 40). The functional, psychological, and cognitive scores at M12 did not statistically differ between groups.

CONCLUSIONS

A hospital-based, face-to-face, intensivist-led multidisciplinary consultation at ICU discharge then at 3 and 6 months was associated with poor outcome 1 year after ICU.

Impact of a Postintensive Care Unit Multidisciplinary Follow-up on the Quality of Life (SUIVI-REA): Protocol for a Multicenter Randomized Controlled Trial

Background

Critically ill patients are at risk of developing a postintensive care syndrome (PICS), which is characterized by physical, psychological, and cognitive impairments and which dramatically impacts the patient’s quality of life (QoL). No intervention has been shown to improve QoL. We hypothesized that a medical, psychological, and social follow-up would improve QoL by mitigating the PICS.

Objective

This multicenter, randomized controlled trial (SUIVI-REA) aims to compare a multidisciplinary follow-up with a standard postintensive care unit (ICU) follow-up.

Methods

Patients were randomized to the control or intervention arm. In the intervention arm, multidisciplinary follow-up involved medical, psychological, and social evaluation at ICU discharge and at 3, 6, and 12 months thereafter. In the placebo group, patients were seen only at 12 months by the multidisciplinary team. Baseline characteristics at ICU discharge were collected for all patients. The primary outcome was QoL at 1 year, assessed using the Euro Quality of Life-5 dimensions (EQ5D). Secondary outcomes were mortality, cognitive, psychological, and functional status; social and professional reintegration; and the rate of rehospitalization and outpatient consultations at 1 year.

Results

The study was funded by the Ministry of Health in June 2010. It was approved by the Ethics Committee on July 8, 2011. The first and last patient were randomized on December 20, 2012, and September 1, 2017, respectively. A total of 546 patients were enrolled across 11 ICUs. At present, data management is ongoing, and all parties involved in the trial remain blinded.

Conclusions

The SUVI-REA multicenter randomized controlled trial aims to assess whether a post-ICU multidisciplinary follow-up improves QoL at 1 year.

Association between social capital and depression among critically ill patients: evidence from a cross-sectional study in rural Shandong, China

BACKGROUND

With an increasing number of critically ill patients, attention should be paid to both their physical health and mental health. The objective of this study is to examine the links between depression and social capital among critically ill patients.

METHODS

Data for 1043 patients with critical illnesses was collected with a stratified cluster random sampling method in rural Shandong, China. Depression symptoms were measured using a short form version of the Center for Epidemiologic Studies Depression Scale (CESD-10) and the total scores of them were dichotomized. We associated structural social capital with social networks, social participation, and social support. Cognitive social capital includes the degree of availability of social trust and reciprocity. Binary logistic regression was used to explore whether social capital was significantly associated with depression among patients with critical illnesses.

RESULTS

We found that 68.5% of the critically ill patients in our sample population had depression. CESD-10 scores were negatively correlated with social capital, including occupations of their frequent contacts, social trust in relatives and friends, distance to the nearest medical institution and medical assistance convenience from non-spouse. In addition, low economic status, and low self-rated health were more significantly correlated with depression in critically ill patients.

CONCLUSIONS

Our findings suggest that more attention should be paid to the mental health of critically ill patients and more formal society, community and government support form given, particularly in rural China.

Suicide and self-harm in adult survivors of critical illness: population based cohort study

OBJECTIVE

To analyse the association between survival from critical illness and suicide or self-harm after hospital discharge.

DESIGN

Population based cohort study using linked and validated provincial databases.

SETTING

Ontario, Canada between January 2009 and December 2017 (inclusive).

PARTICIPANTS

Consecutive adult intensive care unit (ICU) survivors (≥18 years) were included. Linked administrative databases were used to compare ICU hospital survivors with hospital survivors who never required ICU admission (non-ICU hospital survivors). Patients were categorised based on their index hospital admission (ICU or non-ICU) during the study period.

MAIN OUTCOME MEASURES

The primary outcome was the composite of death by suicide (as noted in provincial death records) and deliberate self-harm events after discharge. Each outcome was also assessed independently. Incidence of suicide was evaluated while accounting for competing risk of death from other causes. Analyses were conducted by using overlap propensity score weighted, cause specific Cox proportional hazard models.

RESULTS

423 060 consecutive ICU survivors (mean age 61.7 years, 39% women) were identified. During the study period, the crude incidence (per 100 000 person years) of suicide, self-harm, and the composite of suicide or self-harm among ICU survivors was 41.4, 327.9, and 361.0, respectively, compared with 16.8, 177.3, and 191.6 in non-ICU hospital survivors. Analysis using weighted models showed that ICU survivors (v non-ICU hospital survivors) had a higher risk of suicide (adjusted hazards ratio 1.22, 95% confidence interval 1.11 to 1.33) and self-harm (1.15, 1.12 to 1.19). Among ICU survivors, several factors were associated with suicide or self-harm: previous depression or anxiety (5.69, 5.38 to 6.02), previous post-traumatic stress disorder (1.87, 1.64 to 2.13), invasive mechanical ventilation (1.45, 1.38 to 1.54), and renal replacement therapy (1.35, 1.17 to 1.56).

CONCLUSIONS

Survivors of critical illness have increased risk of suicide and self-harm, and these outcomes were associated with pre-existing psychiatric illness and receipt of invasive life support. Knowledge of these prognostic factors might allow for earlier intervention to potentially reduce this important public health problem.

The impact of intensive care in a private hospital on patients aged 80 and over: health-related quality of life, functional status and burden versus benefit

BACKGROUND

Greater numbers of persons aged over 80 years are admitted to intensive care units (ICU) compared with 15 years ago. Outcomes other than death such as physical dependence and cognitive impairment and treatment burden are important to older people.

AIMS

The aims of this study were to determine the long-term outcomes of functional impairment, health-related quality of life (HRQoL) and the self-reported burden of treatment in a sample of patients aged 80 years and above admitted to ICU. Half of the cohort were admitted for elective cardiac surgery, the rest for non-cardiac surgery and medical conditions.

METHODS

In this longitudinal cohort study, in a tertiary level ICU, we measured HRQoL using the SF-36 and functional status using the modified Barthel Index at several time points over a 2-year follow-up period. We also assessed treatment burden by asking participants whether they thought the episode of care was worthwhile.

RESULTS

A total of 348 patients was recruited into the study. One-fifth of the cohort had died by the 2-year follow-up data collection point. There was an improvement in physical functioning in the cardiac surgery group at 6 months which was not sustained. There was no change in HRQoL at 2 years in either group. The majority valued the episode of care.

CONCLUSION

We demonstrated that HRQoL and previous lifestyle is preserved in the majority following ICU admission, associated with a high level of patient valuation of the episode of care.

Sedation and its psychological effects following intensive care

Significant psychological impacts, including post-traumatic stress disorder (PTSD), have been associated with patients under sedation in intensive care units (ICUs). However, it remains unknown if and how sedation is related to post-ICU psychological outcomes. This literature review explores the relationships between sedation, the depth of sedation and psychological disorders. A review of existing literature was undertaken systematically with key terms and included peer-reviewed primary research and randomised controlled trials (RCTs). To ensure subject relevance pre-2006, non-English and paediatric-based research was excluded. Findings highlighted that reduced sedation levels did not significantly reduce the outcome of PTSD, yet reduced ICU length of stay and length of mechanical ventilation (MV) were both associated with lighter sedation. Further research is recommended into more specific factual and delusional memories post ICU in relation to the level of sedation and to psychological distress.

Emotional sequelae among survivors of critical illness: a long-term retrospective study

CONTEXT

Treatment in an ICU can be stressful and traumatic for patients, and can lead to various physical, psychological and cognitive sequelae.

OBJECTIVES

The aim of the study was to assess the influence of the social, economic and working status of individuals in regard to long-term anxiety and depression among ICU convalescents.

DESIGN

Retrospective, cross-sectional, 5-year survey between 2005 and 2009.

SETTING

The general ICUs of two hospitals in Lublin (Poland): the Teaching Hospital, Medical University of Lublin and the District Hospital.

PATIENTS

All adults surviving an ICU stay of more than 24 h were eligible. In December 2010, 533 questionnaires were sent to discharged ICU survivors, and 195 (36.6%) were returned. One hundred and eighty-six patients were enrolled in the study. Patients with brain injuries were excluded.

MAIN OUTCOME MEASURES

The questionnaire consisted of the Hospital Anxiety and Depression Scale (HADS); questions defining social, economic and working status before and after intensive care stay, health status before intensive care stay, as well as questions about memories and readmissions to intensive care were included.

RESULTS

According to HADS, 34.4% patients had an anxiety disorder and 27.4% were depressed. There was a strong positive correlation between anxiety and depression (r = +0.726, P<0.001). Better material and housing conditions correlated with lower anxiety and depression rates. Acute Physiology and Chronic Health Evaluation II scores on admission positively correlated with both anxiety (r =+0.187; P=0.011) and depression (r = +0.239; P=0.001). A negative correlation between health status before intensive care admission and HADS scores was observed (anxiety rs = -0.193; P=0.008; depression rs = -0.227; P=0.002); better health resulted in less anxiety and depression disorders.

CONCLUSION

Adverse social and economic status is associated with higher rates of anxiety and depression following ICU stay.

Measuring quality of life after intensive care using the Arabic version for Morocco of the EuroQol 5 Dimensions

Background

Health-related quality of life (HRQL) is a relevant outcome measures in intensive care unit (ICU). The aim of this study was to evaluate HRQL of ICU patients 3 months after discharge using the Arabic version for Morocco of the EuroQol-5-Dimension (EQ-5D), and to examine the psychometric properties of the questionnaire.

Results

The Arabic version for Morocco of the EQ-5D was approved by the EuroQol group. A prospective cohort study was conducted after medical ICU discharge. At 3-month follow up, the EQ-5D (self classifier and EQ-VAS) was administered in consultation or by telephone. EQ-VAS varies from 0 (better HRQL) to 100 (worst HRQL). An unweighted scoring for EQ5D-index was calculated. EQ5D-index ranges from -0.59 to 1. Test-retest reliability of the EQ-5D was tested using Kappa coefficient and intraclass correlation coefficient (ICC). Criterion validity was assessed by correlating EQ-VAS and EQ5D-index with the Short Form 36 (SF-36). Construct validity was tested using simple and multiple liner regression to assess factors influencing patients'HRQL. 145 survivors answered the EQ-5D. Median EQ5D-index was 0.52 [0.20-1]. Mean EQ-VAS was 62 ± 20. Test-retest reliability was conducted in 83 patients. ICCs of EQ5D-index and EQ-VAS were 0.95 and 0.92 respectively. For EQ-5D self classifier, agreement by kappa was above 0.40. Significant correlations were noted between EQ5D-index, EQ-VAS and SF-36 (p < 0.001). In multivariate analysis, factors associated with poorer HRQL for EQ5D-index were longer ICU length of stay (β = -0.01; p = 0.017) and higher educational level (β = -0.2; p = 0.001). For EQ-VAS men were associated with better HRQL (β = 6.5; p = 0.048).

Conclusions

The Arabic version for Morocco of the EQ-5D is reliable and valid. Women, high educational level and longer ICU length of stay were associated with poorer HRQL.

A longitudinal qualitative exploration of healthcare and informal support needs among survivors of critical illness: the RELINQUISH protocol

INTRODUCTION AND BACKGROUND

Survival following critical illness is associated with a significant burden of physical, emotional and psychosocial morbidity. Recovery can be protracted and incomplete, with important and sustained effects upon everyday life, including family life, social participation and return to work. In stark contrast with other critically ill patient groups (eg, those following cardiothoracic surgery), there are comparatively few interventional studies of rehabilitation among the general intensive care unit patient population. This paper outlines the protocol for a sub study of the RECOVER study: a randomised controlled trial evaluating a complex intervention of enhanced ward-based rehabilitation for patients following discharge from intensive care.

METHODS AND ANALYSIS

The RELINQUISH study is a nested longitudinal, qualitative study of family support and perceived healthcare needs among RECOVER participants at key stages of the recovery process and at up to 1 year following hospital discharge. Its central premise is that recovery is a dynamic process wherein patients' needs evolve over time. RELINQUISH is novel in that we will incorporate two parallel strategies into our data analysis: (1) a pragmatic health services-oriented approach, using an a priori analytical construct, the 'Timing it Right' framework and (2) a constructivist grounded theory approach which allows the emergence of new themes and theoretical understandings from the data. We will subsequently use Qualitative Health Needs Assessment methodology to inform the development of timely and responsive healthcare interventions throughout the recovery process.

ETHICS AND DISSEMINATION

The protocol has been approved by the Lothian Research Ethics Committee (protocol number HSRU011). The study has been added to the UK Clinical Research Network Database (study ID. 9986). The authors will disseminate the findings in peer reviewed publications and to relevant critical care stakeholder groups.

Critical illness in HIV-infected patients in the era of combination antiretroviral therapy

As HIV-infected persons on combination antiretroviral therapy (ART) are living longer and rates of opportunistic infections have declined, serious non-AIDS-related diseases account for an increasing proportion of deaths. Consistent with these changes, non-AIDS-related illnesses account for the majority of ICU admissions in more recent studies, in contrast to earlier eras of the AIDS epidemic. Although mortality after ICU admission has improved significantly since the earliest HIV era, it remains substantial. In this article, we discuss the current state of knowledge regarding the impact of ART on incidence, etiology, and outcomes of critical illness among HIV-infected patients. In addition, we consider issues related to administration of ART in the ICU and identify important areas of future research.

Observational study of admission and triage decisions for patients referred to a regional intensive care unit

The objectives of this study were to identify factors associated with decisions concerning triage and admission to the intensive care unit and to describe the outcome of patients referred to intensive care unit for admission. The study was a single-centre, prospective, observational study. It was performed in the general intensive care unit of a tertiary regional hospital, over the period of February to June 2009. The patients were non-elective, acute medical in-patients. For 100 patients referred, only 36 were admitted to the intensive care unit. The remaining 64 were declined admission: nine were declined admission because they were assessed as too sick to benefit, 41 were declined admission because they were assessed as too well to benefit and 14 were deemed to potentially benefit from intensive care unit admission but were not admitted ('triage'). Patients most likely to receive triage decisions were medical in-patients who had expressed wishes about end-of-life care, who were functionally limited with co-morbid conditions affecting their performance status. Patients referred by Resident Medical Officers were also more likely to receive a triage decision. Age, gender Aboriginal and Torres Strait Islander status, diagnostic category and reason for referral did not impact on admission or triage decisions. Bed status in intensive care unit at the time of referral affected neither admission nor triage decisions. Hospital mortality in patients deemed too well to benefit from intensive care unit was 7.3%, suggesting that all patients referred for consideration of admission to intensive care unit should be classified as 'high risk'.

Health-related quality of life in Australian survivors of critical illness

OBJECTIVE

To document health-related quality of life of an Australian sample of intensive care unit survivors 6 months after intensive care unit discharge and compare this with preadmission health-related quality of life, health-related quality of life of national population norms, and international samples of intensive care unit survivors.

DESIGN

Prospective observational single-center study.

SETTING

Eighteen-bed medical-surgical tertiary intensive care unit of an Australian metropolitan hospital.

PATIENTS

Of the 122 eligible patients, 100 were recruited (intensive care unit length of stay >48 hrs, age >18 yrs, not imminently at risk of death) and the final sample comprised 67 patients, age (median [interquartile range], 61 yrs [49-73 yrs]), 60% male admitted to the intensive care unit for a median [interquartile range] 101 hrs (68-149 hrs). Normative age- and sex-matched Australian Short-Form 36 data from the Australian Bureau of Statistics, selected international cohorts of intensive care unit survivors, and their respective national age-matched normative data were included for comparison.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Sixty-seven participants provided responses to questions rating health-related quality of life (Australian Short-Form 36) at preadmission (on admission to the intensive care unit or through retrospective recall as soon as able) and 6 months after intensive care unit discharge. Ten additional participants were unable to provide study data without proxy input and were excluded from analysis. Participants reported clinically meaningful improvements in bodily pain (p = .001), social functioning (p = .03), role-emotional domains of the Short-Form 36 (p = .04), and mental component summary score (p = .01) at 6 months after intensive care unit discharge, mostly attributable to the patients undergoing cardiac surgery, whereas remaining Short-Form 36 domains showed no difference between preadmission and 6 months (p > .05). Participants reported clinically meaningful decrements in preadmission Short-Form 36 data compared with the Australian normative population with role-physical (p < .001) and physical functioning (p < .001) most affected at follow-up. Health-related quality of life in this sample was comparable with international samples of intensive care unit survivors.

CONCLUSIONS

Although the majority of health-related quality of life domains did not differ between preadmission and 6-month follow-up, participants reported significant and clinically meaningful improvements in pain and mental health at follow-up. Critical illness survivors' health-related quality of life remained within 1 sd of Australian norms at follow-up and physical function health-related quality of life was most affected. Health-related quality of life in these Australian survivors of the intensive care unit was comparable with international survivors 6 months after intensive care unit admission.

Healthcare Utilisation among Patients Discharged from Hospital after Intensive Care

Surviving critical illness can be life-changing and presents new healthcare challenges for patients after hospital discharge. This feasibility study aimed to examine healthcare service utilisation for patients discharged from hospital after intensive care unit stay. Following Ethics Committee approval, patients aged 18 years and older were recruited over three months. Those admitted after cardiac surgery, discharged to another facility or against medical advice were excluded. Patients were informed of the study by post and followed-up by telephone at two and six months after discharge. General practitioners were also contacted (44% responded). Among 187 patients discharged from hospital, 11 died, 25 declined to participate and 39 could not be contacted. For 112 patients (60%) who completed a survey, the majority (82%) went home from hospital and were cared for by their partner (53%). More than half of the patients (58%) reported taking the same number of medications after intensive care unit stay but 30% took more (P=0.023). While there was no change in the number of visits to the general practitioner for 64% of patients, 29% reported an increase after intensive care unit stay. At six months, 40% of responders who were not retired were unemployed. Discharge summary surveys revealed 39 general practitioners (71%) were satisfied with details of ongoing healthcare needs. Twenty-one general practitioners wrote comments: 10 reported insufficient information about ongoing needs/rehabilitation and two reported no mention of intensive care unit stay. Survivors of critical illness had increased healthcare needs and despite most returning home, had a low workforce participation rate. This requires further investigation to maximise the benefits of survival from critical illness.

Quality of life in the five years after intensive care: a cohort study

INTRODUCTION

Data on quality of life beyond 2 years after intensive care discharge are limited and we aimed to explore this area further. Our objective was to quantify quality of life and health utilities in the 5 years after intensive care discharge.

METHODS

A prospective longitudinal cohort study in a University Hospital in the UK. Quality of life was assessed from the period before ICU admission until 5 years and quality adjusted life years calculated.

RESULTS

300 level 3 intensive care patients of median age 60.5 years and median length of stay 6.7 days, were recruited. Physical quality of life fell to 3 months (P = 0.003), rose back to pre-morbid levels at 12 months then fell again from 2.5 to 5 years after intensive care (P = 0.002). Mean physical scores were below the population norm at all time points but the mean mental scores after 6 months were similar to those population norms. The utility value measured using the EuroQOL-5D quality of life assessment tool (EQ-5D) at 5 years was 0.677. During the five years after intensive care unit, the cumulative quality adjusted life years were significantly lower than that expected for the general population (P < 0.001).

CONCLUSIONS

Intensive care unit admission is associated with a high mortality, a poor physical quality of life and a low quality adjusted life years gained compared to the general population for 5 years after discharge. In this group, critical illness associated with ICU admission should be treated as a life time diagnosis with associated excess mortality, morbidity and the requirement for ongoing health care support.

[Relevance of quality of life questionnaires in women with endometriosis]

High recurrence rates have been reported in women treated for endometriosis despite advances in medical and surgical treatments improving both fertility and symptoms. It should therefore be considered a chronic disorder. In this particular setting, the main objectives for practitioners are to limit disease progression, recurrence and to improve quality of life (QOL). Previous studies have demonstrated a relation between an increase in pain intensity and a decrease in QOL. However, visual analogue scales to measure general well-being are insufficient to quantify the impact of endometriosis on QOL. Several generic questionnaires, mainly the SF-36, are available in various languages but are not specific of women with endometriosis. Some specific questionnaires are available but have been validated in English population for the most part rending comparison between countries difficult. Despite these limits, QOL should be systematically monitored over time by a validated questionnaire for this chronic disorder and could be a criterion for therapeutic strategy.

Evaluation of the effect of prospective patient diaries on emotional well-being in intensive care unit survivors: a randomized controlled trial

OBJECTIVE

To evaluate the effect of a prospective diary intervention on levels of anxiety and depression in a group of intensive care unit survivors.

DESIGN

Pragmatic randomized controlled trial.

SETTING

Adult intensive care unit, medical/surgical wards of a district general hospital and community bases.

PATIENTS

A total of 36 patients who were admitted to the intensive care unit between March 2006 and March 2007 for a minimum of 48 hrs.

INTERVENTIONS

Prospective diary kept by nursing staff for the duration of the patient's stay on intensive care unit, containing daily information about their physical condition, procedures and treatments, events occurring on the unit, and significant events from outside the unit.

MEASUREMENT AND MAIN RESULTS

At initial assessment, almost half of patients fell into the "disorder likely" category on the Hospital Anxiety and Depression Scale (44% for anxiety and 47.2% for depression). Paired-samples Student's t tests to compare the Hospital Anxiety and Depression Scale scores at time 1 and time 2 in the two participant groups revealed that the experimental group displayed statistically significant decreases in both anxiety (t (1,17) = 2.65, p < 0.05) and depression (t (1,17) = 3.33, p < 0.005) scores, while the control group did not, a difference attributed to the diary intervention.

CONCLUSIONS

Survivors of critical illnesses are likely to experience clinically significant symptoms of anxiety and depression following their discharge from hospital. The prospective diary intervention designed to help patients understand what happened to them in intensive care and it has a significant positive impact on anxiety and depression scores almost 2 months after patients' discharge from intensive care unit. Attempts to replicate these results using larger samples are therefore encouraged, with the aim of informing best practice guidelines.

From rehabilitation to optimal function: role of clinical exercise therapy

PURPOSE OF REVIEW

Increasing numbers of critically ill and injured patients are surviving their initial hospitalization. The immobilization associated with long-term critical care can lead to deterioration of the musculoskeletal system within 6 h of bed rest, and muscle strength can decline by as much as 40% within a week of immobilization.

RECENT FINDINGS

The physical, emotional, and social deficits consequent to immobilization persist despite current rehabilitation, and a substandard quality of life following the event ensues for as long as 7 years post-trauma. The cause of decline in quality of life is believed to stem most directly from the physical impact of illness, resulting in such impairments as weakness, fatigue, and difficulty in mobilization.

SUMMARY

Physical therapy is a necessary component of the rehabilitation process. Although physical therapy often succeeds in restoration of the activities of daily life, patients are often unequipped to resume their pretrauma level of activity or functional capacity, including return to work or school. We opine that a vigorous program of physical training implemented soon after discharge from physical therapy is a logical and cost-effective extension of the continuum of rehabilitation after critical illness. Such extension, supervised by an advanced exercise specialist, addresses many physical limitations that persist after critical illness and limit functional recovery.

Study protocol: the Intensive Care Outcome Network ('ICON') study

Background

Extended follow-up of survivors of ICU treatment has shown many patients suffer long-term physical and psychological consequences that affect their health-related quality of life. The current lack of rigorous longitudinal studies means that the true prevalence of these physical and psychological problems remains undetermined.

Methods/Design

The ICON (Intensive Care Outcome Network) study is a multi-centre, longitudinal study of survivors of critical illness. Patients will be recruited prior to hospital discharge from 20–30 ICUs in the UK and will be assessed at 3, 6, and 12 months following ICU discharge for health-related quality of life as measured by the Short Form-36 (SF-36) and the EuroQoL (EQ-5D); anxiety and depression as measured by the Hospital Anxiety and Depression Scale (HADS); and post traumatic stress disorder (PTSD) symptoms as measured by the PTSD Civilian Checklist (PCL-C). Postal questionnaires will be used.

Discussion

The ICON study will create a valuable UK database detailing the prevalence of physical and psychological morbidity experienced by patients as they recover from critical illness. Knowledge of the prevalence of physical and psychological morbidity in ICU survivors is important because research to generate models of causality, prognosis and treatment effects is dependent on accurate determination of prevalence. The results will also inform economic modelling of the long-term burden of critical illness.

'One patient amongst many': a qualitative analysis of intensive care unit patients' experiences of transferring to the general ward

Introduction

Many patients experience 'relocation stress' when they are transferred from an intensive care unit (ICU) to step-down (high dependency) or general ward care, and much has been written about the psychological causes. This qualitative analysis of in-depth, narrative interviews with former ICU patients explores and examines patients' accounts in order to identify additional causes of relocation stress.

Methods

Forty former ICU patients were recruited throughout the UK, using maximum variation sampling, to achieve a broad range of experiences of intensive care. Interviews in people's homes were recorded on video and audio equipment as part of a study for the Database of Personal Experiences of Health and Illness (DIPEx) web resource. All interviews were transcribed, checked and returned to respondents. For this report, a qualitative thematic analysis was used to explore experiences of transfer.

Results

We found that most people experienced relocation distress not only because of physical and emotional difficulties relating to their illness and treatment and the inevitable anxiety resulting from leaving a protected environment, but also from concrete, practical causes. These included specific concerns about communication, feeding, nursing care and support, as well as ward organization and environment. Written excerpts from the interviews and two video excerpts taken from the DIPEx website illustrate our findings.

Conclusion

We conclude that there are several aspects of care that deserve further examination by researchers and service providers, and that not all of the factors associated with relocation stress should be seen as an inevitable consequence of the psychological adjustment involved in transfer from an ICU.

Life beyond severe traumatic injury: an integrative review of the literature

It is only recently that recognition of the serious and debilitating sequelae of trauma has prompted exploration of outcomes beyond survival, such as disability, health status and quality of life. This paper aims to review the literature describing outcomes following severe traumatic injury to provide clinicians with a greater understanding of the recovery trajectory following severe trauma and highlight the issues faced by those recovering from such injury. Electronic databases, published reference lists and the Internet were searched to identify relevant literature. The heterogeneous nature of published literature in this area prohibited a systematic approach to inclusion of papers in this review. Trauma survivors report significant sequelae that influence functional status, psychological wellbeing, quality of life and return to productivity following severe injury. Key themes that emerge from the review include: current trauma systems which provide inadequate support along the recovery trajectory; rehabilitation referral which is affected by geographical location and provider preferences; a long-term loss of productivity in both society and the workplace; a high incidence of psychological sequelae; a link between poor recovery and increased drug and alcohol consumption; and valued social support which can augment recovery. Future research to evaluate interventions which target the recovery needs of the severely injured patients is recommended. Particular emphasis is required to develop systematic, sustainable and cost-effective follow-up to augment the successes of existing acute trauma services in providing high quality acute resuscitation and definitive trauma management.

Quality of life outcome of critical care survivors eighteen months after discharge from intensive care

AIM

To assess the changes in health-related quality of life in patients discharged from the intensive care unit (ICU).

METHODS

At the General University ICU, Trauma Hospital in Athens, 242 patients were enrolled prospectively over a study period of 18 months. Out of these, 116 participants (47.9%) completed all survey components at 6, 12, and 18 months. We used Quality of Life-Spanish (QOL-SP) to assess the health-related quality of life. Patients or their relatives were interviewed on ICU admission and at 6, 12, and 18 months after discharge from the ICU.

RESULTS

Mean quality of life score of the patients increased from 2.9+/-4.8 (out of maximum 25 points) on ICU admission to 7.0+/-7.2 points at 6 months after discharge, and then decreased to 5.6+/-6.9 points at 18 months (P<0.001; Friedman Test). Multilinear regression analysis showed that the variables which had the strongest association with the quality of life on admission were age (P=0.002) and male sex (P=0.001), whereas age (P<0.001), length of ICU stay (P<0.001), and male sex (P=0.002) had the strongest association 18 months after discharge from the ICU. Survival rate was 66.9% at discharge from ICU and 61.6% at hospital discharge. There were 33% deaths in the ICU, 5.3% in the hospital, and 6.2% after ICU discharge. There were 7.4% patients lost to follow-up.

CONCLUSIONS

After discharge from the ICU, patients' quality of life was poor and showed an improvement at 18 months after discharge, but was still worse than on admission. Age, ICU length of stay, and male sex were the factors that had the strongest impact on the quality of life on admission and at 18 months after discharge from the ICU.

Health related quality of life six months following surgical treatment for secondary peritonitis--using the EQ-5D questionnaire

BACKGROUND

To compare health related quality of life (HR-QoL) in patients surgically treated for secondary peritonitis to that of a healthy population. And to prospectively identify factors associated with poorer (lower) HR-QoL.

DESIGN

A prospective cohort of secondary peritonitis patients was mailed the EQ-5D and EQ-VAS 6-months following initial laparotomy.

SETTING

Multicenter study in two academic and seven regional teaching hospitals.

PATIENTS

130 of the 155 eligible patients (84%) responded to the HR-QoL questionnaires.

RESULTS

HR-QoL was significantly worse on all dimensions in peritonitis patients than in a healthy reference population. Peritonitis characteristics at initial presentation were not associated with HR-QoL at six months. A more complicated course of the disease leading to longer hospitalization times and patients with an enterostomy had a negative impact on the mobility (p = 0.02), self-care (p < 0.001) and daily activities: (p = 0.01). In a multivariate analysis for the EQ-VAS every doubling of hospital stay decreases the EQ-VAS by 3.8 points (p = 0.015). Morbidity during the six-month follow-up was not found to be predictive for the EQ-5D or EQ-VAS.

CONCLUSION

Six months following initial surgery, patients with secondary peritonitis report more problems in HR-QoL than a healthy reference population. Unfavorable disease characteristics at initial presentation were not predictive for poorer HR-QoL, but a more complicated course of the disease was most predictive of HR-QoL at 6 months.

Theoretical model of coping among relatives of patients in intensive care units: a simultaneous concept analysis

This paper reports the development of a theoretical model of relatives' coping approaches during the patient's intensive care unit stay and subsequent recovery at home by performing an analysis of concepts generated from two empirically grounded, theoretical studies in this area.

BACKGROUND

When supporting relatives of intensive care unit patients, it is important that nurses have access to evidence-based knowledge of relatives' coping approaches during the period of illness and recovery.

METHOD

Simultaneous concept analysis was used to refine and combine multiple coping concepts into a theoretical model of coping. The concepts were generated in two previous empirical studies of relatives' coping approaches during mechanically ventilated patients' intensive care unit stays and recovery at home.

FINDINGS

The theoretical model was developed in 2004-2005 and illustrates the effectiveness of different coping approaches in relation to each other and to social support. Definitions summarizing each coping approach and containing the knowledge gained through the simultaneous concept analysis method were also formulated.

CONCLUSION

This middle-range theory of relatives' coping approaches may make a valuable contribution to international intensive care unit nursing practice, especially as it is based on empirical studies and may therefore serve as a basis for the development of future clinical guidelines. However, the theoretical model needs to be empirically validated before it can be used.

Physical and psychological sequelae of critical illness

OBJECTIVES

To measure levels of anxiety, depression and post-traumatic stress among survivors of a critical illness and to relate these symptoms to general health parameters.

DESIGN

A prospective study of patients who had spent a minimum 3 days (median 9 days) in a general intensive care unit (ICU). Of these patients, 51 were interviewed 3 months after discharge and 45 of them were reviewed at 9 months.

METHODS

General health was assessed by a physical symptom score, the EuroQol 'thermometer' and the Short Form 36 (SF-36) questionnaire. Physical and mental component summary measures (PCS, MCS) were calculated from the SF-36 data. Psychological health was assessed using both the Hospital Anxiety and Depression Scale and the Impact of Events Scale.

RESULTS

At both 3 and 9 months after ICU discharge 24% of patients qualified as a 'case' of anxiety, while similar figures were seen for intrusion (24 and 20%). The incidence of depression (35 and 47%) and avoidance (36 and 38%) was higher on each occasion. Four of the eight SF-36 domains improved with time, as did PCS (from 29.0 to 35.4), but there was no significant difference in physical symptom score, EuroQol value or MCS. Strong correlations were seen between the physical and psychological parameters at each time point.

CONCLUSIONS

A substantial proportion of patients who survive a critical illness show evidence of anxiety and depression up to 9 months later, and most of them also have symptoms indicative of post-traumatic stress. Delayed physical recovery may contribute to this psychological morbidity. ICU follow-up clinics should be able to detect patients suitable for psychological intervention.

A national survey of intensive care follow-up clinics

Intensive care follow-up clinics allow extended review of survivors of critical illness. However, the current provision of intensive care follow-up clinics in the UK is unknown. We performed a survey of intensive care follow-up clinic practice in the UK. A questionnaire was sent to 298 intensive care units in the UK to determine the number of follow-up clinics and details of current follow-up practice. Responses were received from 266 intensive care units, an 89% response rate. Eighty units (30%) ran a follow-up clinic. Only 47 (59%) of these clinics were funded. Of those intensive care units without a follow-up clinic, 158 (88%) cited 'financial constraints' as the reason. Over half of the follow-up clinics (44 clinics, 55%) were nurse-led, and the majority (56 clinics, 77%) only routinely review patients treated on the intensive care unit for 3 or 4 days or longer. Nearly half of the follow-up clinics (39 clinics, 49%) have pre-negotiated access to at least one other out-patient service.

A self-report-based study of the incidence and associations of sexual dysfunction in survivors of intensive care treatment

OBJECTIVES

To determine the incidence and associations of sexual dysfunction in survivors of intensive care unit treatment in their first year after hospital discharge using a self-report measure.

DESIGN

A prospective observational study.

SETTING

ICU Follow-up Clinic, The Royal Berkshire Hospital, Reading.

SUBJECTS

One hundred and twenty-seven patients aged 18 years and over who spent 3 days or more in the intensive care unit.

MAIN OUTCOME MEASURES

Demographic data; reported incidence of sexual dysfunction and post-traumatic stress disorder symptomatology; association between reported sexual dysfunction and age, gender, post-traumatic stress disorder symptomatology and length of intensive care unit stay; patient and partner satisfaction with current sex life.

RESULTS

Fifty-two patients (43.6%) reported symptoms of sexual dysfunction. There was a significant association between sexual dysfunction and post-traumatic stress disorder symptomatology (p = 0.019). There was no association between reported sexual dysfunction and gender (p = 0.33), age (p = 0.8) or intensive care unit length of stay (p = 0.41). Forty-five per cent of patients and 40% of partners were not satisfied with their current sex life. No other medical practitioner had sought symptoms of sexual dysfunction during the study period.

CONCLUSIONS

Symptoms of sexual dysfunction are common in patients recovering from critical illness and appear to be significantly associated with the presence of post-traumatic stress disorder symptomatology. The intensive care unit follow-up clinic is a suitable forum for the screening and referral of patients with sexual dysfunction.

Effects of prolonged intensive care unit stay on quality of life and long-term survival after transthoracic esophageal resection

OBJECTIVE

There are few prospective data on the effects of prolonged intensive care unit stay on the quality of life and long-term survival of a homogeneous patient population. Therefore, the aims of this prospective study were a) to describe the quality of life in patients after having a transthoracic esophageal resection; and b) to analyze the influences of a prolonged intensive care unit stay on quality of life and survival in patients after esophageal cancer resection who survived to hospital discharge.

DESIGN

Prospective study.

SETTING

Medical center.

PATIENTS

The study population consisted of 109 patients undergoing a transthoracic resection for adenocarcinoma of the middistal esophagus or gastric cardia between April 1994 and February 2000.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

A comparison was made between patients staying <or=5 days vs. >or=6 days in the intensive care unit and also <or=2 days vs. >or=14 days. Quality of life was assessed in all patients by mailed self-report questionnaires at baseline (preoperatively), at 5 wks, and at 3, 6, 9, 12, 18, 24, 30, and 36 months after surgery. Daily physical, emotional, and social functioning was assessed with the generic Medical Outcome Studies Short Form-20. Disease-specific quality of life was measured by an adapted Rotterdam Symptom Check List. Quality of life data were gathered between July 1994 and March 2003. Five of the 109 patients died in the hospital and were excluded from the analysis. All five of them were in the intensive care unit >or=6 days. Of the remaining 104 patients, 92 provided baseline scores. The data of the 92 patients were used for the quality of life analyses. For the clinicopathologic and survival analysis, the data of 104 hospital survivors were used. Patients spent a median of 5.5 days (range 0-71) in the intensive care unit. The Medical Outcome Studies Short Form-20 and the Rotterdam Symptom Check List measurements showed no clear differences in long-term quality of life between patients after a short vs. a prolonged postoperative intensive care unit period. The median overall survival in all patients was 2.0 yrs (range 0.1-8.0). Median overall survival in patients staying in the intensive care unit <or=5 days was 1.9 yrs (range 0.3-7.4 yrs) vs. 2.7 yrs (range 0.9-7.2 yrs) in patients staying >or=6 days (p = .9, log-rank test). Median overall survival in patients staying in the intensive care unit <or=2 days was 1.7 yrs (range 1.2-2.6 yrs) vs. 2.0 yrs (range 0.2-3.8 yrs) in patients staying >or=14 days (p = .74, log-rank test).

CONCLUSIONS

For patients who survived to hospital discharge after transthoracic esophagectomy, there was no difference in long-term quality of life or survival between those submitted to the intensive care unit for a short period vs. a long period.

Prolonged cognitive dysfunction in survivors of critical illness

A prospective study using neuropsychological testing explored cognitive performance, and specifically executive function, in survivors of critical illness during the first year of recovery. Fifty-one patients who had survived 3 days or more in the intensive care unit were studied approximately 3 months after discharge; 45 of them were studied again 6 months later. General health was assessed using the Short-Form 36. Cognitive and executive functions were measured using Raven's Progressive Matrices, the Hayling Sentence completion test and the Six-Element Test. Three months after discharge from intensive care, all eight domains of Short-Form 36 were impaired among survivors; by 9 months, four of the eight domains showed significant improvement. At 3 months, 35% of patients scored at or below a level equivalent to the lowest performing 5% of a normal population (i.e. the fifth percentile) on two or more tests of cognitive function; by 9 months only 4% of patients were impaired to this extent. Although cognitive performance improved with time, it remained below normal.

Long-term survival from intensive care: a review

OBJECTIVE

To determine whether the long-term benefit of an ICU requires prolonged patient follow-up we reviewed long-term survival of patients from general ICUs.

METHOD

We carried out a computerised search of online databases Medline (1966-2004), Embase (1966-2004) and Cochrane Library (1966-2004) for studies reporting patients' long-term survival for greater than 12 months from general ICUs. SELECTED STUDIES: We identified 19 studies that met the selection criteria. The casemix and severity of illness varied. Differences included the services provided, investigator inclusion/exclusion criteria and proportion of medical patients (range 13-79%).

RESULTS

Mean reported ICU length of stay was 5.3 days. The study initiation time for follow-up varied (mostly from time of ICU admission), as did the duration of follow-up (16 months-13 years). ICU and hospital mortality rates ranged from 8% to 33% and 11% to 64%, respectively. The reported 5-year mortality ranged from 40% to 58%.

CONCLUSIONS

Well designed studies on long-term outcomes are needed to demonstrate the value of intensive care. Deficiencies in design, methodology, and reporting make interpretation and comparison difficult. Recommendations are made for the reporting of outcome from the ICU. Optimum duration of follow-up has not been determined.

Psychosocial adaptation in relatives of critically injured patients admitted to an intensive care unit

The aim of this study is to analyze how the length of time a patient spends in an Intensive Care Unit (ICU) affects close relatives, with regard to specific clinical variables of personality, family relationships and fear of death. The study group consisted of 57 relatives of seriously ill patients admitted to the ICU of "Virgen del Rocío" Rehabilitation and Trauma Hospital (Seville, Spain). The instruments applied were: a psychosocial questionnaire, clinical analysis questionnaire, family environment scale and fear of death scale. The relatives of patients admitted to ICU obtained higher scores in hypochondria, suicidal depression, agitation, anxious depression, guilt-resentment, paranoia, psychasthenia, psychological maladjustment and self-expression, and less in fear of their own death, as when compared to interviews with the same relatives 4 years later. The length of time a patient spent in the ICU influenced relatives in some clinical variables of personality, family relationships and fear of death

Does ICU length of stay influence quality of life?

BACKGROUND

Patients with prolonged stay in the intensive care unit (ICU) use a disproportionate share of resources. However, it is not known if such treatment results in impaired quality of life (QOL) as compared to patients with a short length of stay (LOS) when taking into account the initial severity of illness.

METHODS

Prospective, observational case-control study in a university hospital surgical and trauma adult ICU. All patients admitted to the ICU during a 1-year period were included. Patients with a cumulative LOS in the ICU > 7 days, surviving up to 1 year after ICU admission and consenting were identified (group L, n = 75) and matched to individuals with a shorter stay (group S). Matching criteria were diagnostic group and severity of illness. Health-related quality of life (HRQOL) was assessed 1 year after admission using the short-form 36 (SF-36) and was compared between groups and to the general population. Further, overall QOL was estimated using a visual analogue scale (VAS) and willingness to consent to future intensive care, and was compared between groups L and S.

RESULTS

Based on ANCOVA, a significant difference between groups L and S was noted for two out of eight scales: role physical (P = 0.033) and vitality (P = 0.041). No differences were found for the physical component summary (P = 0.065), the mental component summary (P = 0.267) or the VAS (P = 0.316). Further, there was no difference in expectation to consent to future intensive care (P = 0.149). As compared to the general population, we found similar scores for the mental component summary and for three of eight scales in group L and five of eight scales in group S.

CONCLUSIONS

When taking into account severity of illness, HRQOL 1 year after intensive care is comparable between patients with a short and a long LOS in the ICU. Thus, prolonged stay in the ICU per se must not be taken as an indicator of future poorer HRQOL. However, as compared to the general population, significant differences, mostly in physical aspects of QOL, were found for both groups of patients.

Psychological implications of admission to critical care

Admission to critical care can have far-reaching psychological effects because of the distinct environment. Critical care services are being re-shaped to address long-term sequelae, including post-traumatic stress disorder, anxiety and depression. The long-term consequences of critical illness not only cost the individual, but also have implications for society, such as diminished areas of health-related quality-of-life in sleep, reduced ability to return to work and enjoy recreational activities (Audit Commission, 1999; Hayes et al, 2000). The debate around the phenomenon of intensive care unit (ICU) syndrome is discussed with reference to current thinking. After critical care, patients may experience amnesia, continued hallucinations or flashbacks, anxiety, depression, and dreams and nightmares. Nursing care for patients while in the critical care environment can have a positive effect on psychological well-being. Facilitating communication, explaining care and rationalizing interventions, ensuring patients are oriented as to time and place, reassuring patients about transfer, providing patients,where possible, with information about critical care before admission and considering anxiolytic use, are all practices that have a beneficial effect on patient care. Follow-up services can help patients come to terms with their experiences of critical illness and provide the opportunity for them to access further intervention if desired. Working towards providing optimal psychological care will have a positive effect on patients' psychological recovery and may also help physical recuperation after critical care.

A qualitative study of the experiences of patients following transfer from intensive care

In nursing literature much attention has been paid to patients' experiences while in intensive care. Extensive literature exists examining the longer-term effects of critical care [Jones C, Humphris GM, Griffiths RD. Psychological morbidity following critical illness - the rationale for care after intensive care. Clinical Intensive Care 1998;9:199-205; Griffiths RD, Jones C. ABC of intensive care. Recovery from intensive care. Br Med J 1999;319:417-429]. There is an apparent scarcity of data examining patients' experiences immediately following discharge to wards. A Husserlian phenomenological approach was utilised to gain some understanding of the experience of patients following transfer from intensive care. Ten patients selected purposively comprised the sample. Interviews were performed on the wards 3-5 days following transfer from intensive care. Data was analysed utilising () [Colaizzi PF. Psychological Research as the phenomenologist views it. In: Valle R, King M, editors. Alternatives for psychology. New York: Oxford University Press; 1978. p. 48-71] procedural approach to phenomenological interpretation and analysis. Three major themes emerged: physical response, psychological response and provision of care. These provide a possible framework for patient assessment. Implications for future practice and study are discussed.

Psychological repercussions in family members of hospitalised critical condition patients

OBJECTIVE

We analysed the influence of certain variables [quality of life (QoL) and passage of time] of patients in the intensive care unit (ICU) on other variables (clinical dimensions of personality, family environment, fear of death) of their family members.

METHOD

Fifty-seven family members of ICU patients filled in five questionnaires when the patients stayed in the ICU, and 4 years later, the patients filled in a QoL questionnaire.

RESULTS

The following results were obtained: (1) Passage of time has influence on Agitation, Boredom-withdrawal, Psychopathic Deviation, and Psychological Inadequacy, only in family members of patients with good QoL; (2) family members score higher in Hypochondriasis, Suicidal Depression, Agitation, Anxious Depression, Guilt-resentment, Paranoia, Psychasthenia, Psychological Inadequacy, and Expression, and lower in Fear of the process of another's dying, when the patient was in ICU than 4 years later; (3) family members of patients with bad QoL 4 years after ICU score higher in Hypochondriasis, Suicidal Depression, Agitation, Schizophrenia, Psychasthenia and Psychological Inadequacy than did the family members of patients with good QoL.

Quality of life before and after intensive care

Quality of life is often thought to be poor before and after intensive care unit admission. The aim of this study was to investigate changes in quality of life before and after intensive care. A prospective cohort study of 300 consecutive patients admitted to intensive care was performed in a Scottish Teaching Hospital. Quality of life was assessed premorbidly and 3, 6 and 12 months after intensive care admission for surviving patients using SF-36 as well as EQ-5D scores at 12 months. The median value for age was 60.5 years and for APACHE II score, 18. The mean length of stay was 6.7 days. SF-36 physical component scores decreased from premorbid values at 3 months (p = 0.05) and then returned to premorbid values at 12 months (p < 0.001). The mean physical scores were below the population norm at all time points but the mean mental scores were similar or higher than these population norms. Patients who died after intensive care discharge had lower quality of life scores than did survivors (all p < 0.01). Poor premorbid quality of life was demonstrated and appears to reduce after ICU discharge. For survivors there was a slow increase in physical quality of life to premorbid levels by the end of the first year but these remained lower than in the general population. ICU patients experience a considerable longer-term burden of ill health.

Examining discharge outcomes and health status of critically ill patients: some practical considerations

This prospective observational study examined the outcomes of 200 consecutive admissions to an adult tertiary level Intensive Care Unit (ICU). Eligible and consenting participants were also involved in a sub-study that examined health status at four measurement points from pre-illness to 6 months post-discharge. Of the 189 individual patients admitted, 23% died in ICU and 57% were discharged home. The health status sub-study enrolled 34 participants (39% of eligible patients) who were representative of the ICU population for demographic and clinical variables. Surviving participants returned to a similar, though not identical state of health at 6 months post-discharge, when compared to their pre-ICU health-state using the 15D and SF-36 instruments. Health status at ICU discharge was significantly impaired when compared to other measurement points, particularly for mobility, breathing, eating, usual activities and vitality. A number of methodological challenges were evident, particularly for the health status sub-study, including prospective subject recruitment and retention, losses to follow-up and instrument responsiveness. Despite the limitations noted, the study provided useful findings and recommendations for the continued development of methods to examine the health status of critically ill patients.

Coping strategies of relatives when an adult next-of-kin is recovering at home following critical illness

The trend within the Swedish healthcare system is to reduce the duration of hospital care. This means that a patient who is discharged to their home after critical illness is highly likely to be functionally impaired, and therefore, requires care-giving assistance from a family member. The aim of this study was to generate a theoretical model with regard to relatives' coping when faced with the situation of having an adult next-of-kin recovering at home after critical illness. The design incorporated grounded theory methodology. Four coping strategies exhibiting different characteristics were identified: volunteering, accepting, modulating and sacrificing. Factors determining the choice of coping strategy were the physical and psychological status of the relative, previous experience of ICU-care and the psychological status of the patient. The theoretical model described in this article can contribute to expanding healthcare professionals' understanding of the coping strategies of relatives during recovery, but also provide inspiration for social action to be taken.

The effect of chronic pain on health related quality of life amongst intensive care survivors

Intensive care unit (ICU) survivors report reductions in health-related quality of life (HR-QOL), whilst chronic pain is common in the general population. However, it is unknown whether there are associations between the experience of ICU and the incidence of chronic pain. A questionnaire--Pain Scale, Pain Self-Efficacy Questionnaire (PSEQ), Centre of Epidemiology Study Depression Scale (CES-D Scale) and the Short Form Health Survey (SF-36)--was sent to 99 consenting patients who had been in the ICU for >48 hours. Sixty-six and 52 questionnaires were returned at 1 and 6 months respectively. There was a general limitation in activities of daily living; younger ages (36-65 years) experienced a decease in work performance and other physical activities. Bodily pain increased, general health diminished, and engagements in social activities were severely affected. There was a decline in mental health for those 36-65 years of age. HR-QOL improved over time; 28% experienced chronic pain and had longer hospital length of stay (LOS), tended to have longer ICU LOS and were ventilated for longer. Those with chronic pain had significant reductions in physical function, bodily pain, general health and vitality. Ventilator hours and hospital LOS were associated with risk of chronic pain (OR 1.09, p=0.033 and OR 1.27, p=0.046). HR-QOL in ICU survivors declined, although there was a general improvement from 1-6 months. This decline in HR-QOL affected younger people (less than 65 years) more than older people. Chronic pain is a significant issue post ICU and is associated with poorer HR-QOL.

Follow-up after intensive care: a single center study

OBJECTIVES

To study health problems, quality of life, functional status, and memory after intensive care.

SETTING

Adult patients ( n=346) discharged from a university hospital ICU.

DESIGN AND METHODS

Prospective cohort study. Follow-up patients were found using the ICU database and the Peoples Registry. Quality of life (QOL) was measured with the Short Form 36 (SF-36) 6 months after ICU discharge. Semi-structured interviews, questionnaires, Glasgow Outcome Score (recovery), and Karnofsky Index (functional status) were used at consultations 7-8 months after ICU discharge.

RESULTS

The SF-36 response rate was 64.5%, with scores significantly lower than population scores. Consultation patients ( n=136) did not differ from the rest ( n=210) regarding age, SAPS II scores, length of stay (LOS), and reasons for ICU admission. At follow-up 67.6% of consultation patients continued most activities, 75% looked after themselves, and 64.7% were non-workers, compared to 40.4% before the ICU admission. During and after the ICU stay, 40% lost more than 10 kg body weight. Fifty-eight (43%) could not remember anything from their ICU stay. At follow-up only 22 (16%) could remember having received information during their ICU stay. Three patients needed referral to other specialties.

CONCLUSIONS

We should focus more on optimizing symptom management and giving repeated information after ICU discharge. Nutritional status and weight loss is another area of concern. More research is needed to find out how the broad range of psychosocial and physical problems following an ICU stay relates to the stay.

Family carers of ICU survivors: a survey of the burden they experience

Intensive care unit (ICU) survivors may experience deterioration in their quality of life for months following their return home, with families assuming a caregiving role. The aim of this study was to measure the burden associated with caring for a family member who had been critically ill. The study also sought to describe the relationship between three factors (filial obligation, social support, self-efficacy) and caregiver burden. Seventy-one family carers, 51 females (72%) and 20 (28%) males of long-term intensive care patients completed a mailed survey, after signing an informed consent form. Although the vast majority of the caregivers were providing substantial number of hours of care each week, they scored lower than the midpoint on all caregiver burden inventory subscales. Filial obligation was found to be positively associated with caregiver burden; however, there was no association between social support, self-efficacy and caregiver burden. Male caregivers experienced significantly more burden than female caregivers. The findings suggest that an understanding of the factors that impact on caregiver burden of families of ICU survivors is only beginning to emerge.

Long-term outcome in ICU patients: what about quality of life?

OBJECTIVE

Analysis of mortality and quality of life (QOL) after intensive care unit (ICU) discharge.

DESIGN

Prospective, observational study.

SETTING

Mixed, 31-bed, medico-surgical ICU.

PATIENTS

Consecutive adult ICU admissions between June 25 and September 10, 2000, except admissions for uncomplicated elective postoperative surveillance. INTERVENTIONS. None.

MEASUREMENTS AND RESULTS

Age, past history, admission APACHE II, SOFA score (admission, maximum, discharge), ICU and hospital mortality were recorded. A telephone interview employing the EuroQol 5D system was conducted 18 months after discharge. Of 202 patients, 34 (16.8%) died in the ICU and 23 (11.4%) died in the hospital after ICU discharge. Of the 145 patients discharged alive from hospital, 22 could not be contacted and 27 (13.4%) had died after hospital discharge. Of the 96 patients (47.5%) who completed the questionnaire, 38% had a worse QOL than prior to ICU admission, but only 8.3% were severely incapacitated. Twenty-three patients (24%) had reduced mobility, 15 (15.6%) had limited autonomy, 24 (25%) had alteration in usual daily activities, 29 (30.2%) expressed more anxiety/depression, and 42 (44%) had more discomfort or pain. Twenty-eight (62.2% of those who worked previously) patients had returned to work 18 months after ICU discharge.

CONCLUSIONS

Comparing QOL after discharge with that before admission, patients more frequently report worse QOL for the domains of pain/discomfort and anxiety/depression than for physical domains. Factors commonly associated with a change in QOL were previous problems in the affected domains, prolonged hospital length of stay (LOS), greater disease severity at admission and degree of organ dysfunction during ICU stay.

Triaging patients to the ICU: a pilot study of factors influencing admission decisions and patient outcomes

OBJECTIVE

To assess the appropriateness of ICU triage decisions. DESIGN. Prospective descriptive single-center study.

SETTING

Ten-bed, medical-surgical ICU in an acute-care 460-bed, tertiary care hospital.

PATIENTS

All patients triaged for admission were entered prospectively.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Age, underlying diseases, admission diagnoses, Mortality Probability Model (MPM0) score, information available to ICU physicians, and mortality were recorded. Of the 334 patients (96% medical), 145 (46.4%) were refused. Reasons for refusal were being too-sick-to-benefit (48, 14%) and too-well-to-benefit (93, 28%). Factors independently associated with refusal were patient location, ICU physician seniority, bed availability, patient age, underlying diseases, and disability. Hospital mortality was 23% and 27% for patients admitted to our ICU and other ICUs, respectively, and 7.5% and 60% for patients too well and too sick to benefit, respectively. In the multivariate Cox model, McCabe = 1 [hazard ratio (HR), 0.44 (95% CI, 0.24-0.77), P=0.001], living at home without help (HR, 0.440, 95% CI, 0.28-0.68, P=0.0003), and immunosuppression (HR, 1.91, 95% CI, 1.09-3.33, P=0.02) were independent predictors of hospital death. Neither later ICU admission nor refusal was associated with cohort survival. MPM0 was not associated with hospital mortality.

CONCLUSIONS

Refusal of ICU admission was related to the ability of the triaging physician to examine the patient, ICU physician seniority, patient age, underlying diseases, self-sufficiency, and number of beds available. Specific training of junior physicians in triaging might bring further improvements. Scores that are more accurate than the MPM0 are needed.

Six-month neuropsychological outcome of medical intensive care unit patients

OBJECTIVE

To examine neuropsychological function, depression, and quality of life 6 months after discharge in patients who received mechanical ventilation in the intensive care unit.

DESIGN

Prospective cohort study.

SETTING

Tertiary care, medical and coronary intensive care unit of a university-based medical center.

STUDY POPULATION

A total of 275 consecutive, mechanically ventilated patients from a medical intensive care unit were prospectively followed. At 6 months, 157 were alive, of whom 41 (26%) returned for extensive follow-up testing.

MEASUREMENT AND MAIN RESULTS

Neuropsychological testing and assessment of depression and quality of life were performed at 6-month follow-up. Seven of 41 patients were excluded from further analysis due to preexisting cognitive impairment determined via surrogate interviews using the Modified Blessed Dementia Rating Scale and a review of medical records. On the basis of strict criteria derived from normative data, we found that 11 of 34 patients (32%) were neuropsychologically impaired. Impairment was generally diffuse but occurred primarily in areas of psychomotor speed, visual and working memory, verbal fluency, and visuo-construction. The rate of neuropsychological deficits in the study population was markedly higher than population norms for mild dementia. Scores on the Geriatric Depression Scale-Short Form were significantly more abnormal in the neuropsychologically impaired group than in the nonimpaired group at hospital discharge (p =.04) and at 6-month follow-up (p =.02), and clinically significant depression was found in 27% of impaired subjects at hospital discharge and in 36% at 6-month follow-up. No differences were observed between groups in quality of life as measured with the Short Form Health Survey-12 at discharge or 6-month follow-up.

CONCLUSIONS

Prolonged neuropsychological impairment is common among survivors of the medical intensive care unit and occurs with greater than anticipated frequency when compared with relevant normative data. Future investigations are warranted to elucidate the nature of the association between critical illness, neuropsychological impairment, depression, and decreased quality of life.

Changes in health-related quality of life from 6 months to 2 years after discharge from intensive care

BACKGROUND

Intensive care patients have, both before and after the ICU stay, a health-related quality of life (HRQOL) that differs from that of the normal population. Studies have described changes in HRQOL in the period from before the ICU stay and up to 12 months after. The aim of this study was to investigate possible longitudinal changes in HRQOL in adult patients (>18 years) from 6 months to 2 years after discharge from a general, mixed intensive care unit (ICU) in a university hospital.

METHODS

This is a prospective cohort study. Follow-up patients were found using the ICU database and the Peoples Registry. HRQOL was measured with the Short Form 36 (SF-36) questionnaire. Answers at 6 months and 2 years were compared for all patients, surgical and medical patients, and different admission cohorts.Differences are presented with 95% confidence intervals. The SF-36 data were scored according to designed equations. SPSS 11.0 was used to perform t-tests and Mann-Whitney tests.

RESULTS

A total of 100 patients (26 medical and 74 surgical) answered the SF-36 after 6 months and again after 2 years. There was overall moderate improvement in 6 out of 8 dimensions of the SF-36, and the average increase in score was + 4.0 for all 8 dimensions. The changes for surgical and medical patients were similar. Neurological and respiratory patients reported increased average HRQOL scores, while cardiovascular patients did not. Patients with worsening of scores from 6 months to 2 years were insignificantly older than patients with improved scores (55.3 vs. 49.7 years), and both groups had comparable severity scores (simplified acute physiology score, SAPS II, 37.2 vs. 36.3) and length of ICU stay (2.7 vs. 3.2 days). The statistically significant changes in HRQOL (in the Role Physical and Social Functioning dimensions) were, due to sample size, barely clinically relevant.

CONCLUSION

In a mixed ICU population we found moderate increases in HRQOL both for medical and surgical patients from 6 months to 2 years after ICU discharge, but the sample size is a limitation in this study.
