Health-related quality of life of ICU survivors: review of the literature

Psychological symptoms and health-related quality of life in intubated and non-intubated intensive care survivors: A multicentre, prospective observational cohort study

Objective

To compare long-term psychological symptoms and health-related quality of life (HRQOL) in intubated versus non-intubated ICU survivors.

Design

Prospective, multicentre observational cohort study.

Setting

Four tertiary medical-surgical ICUs in Australia.

Participants

Intubated and non-intubated adult ICU survivors.

Main outcome measures

Primary outcomes: clinically significant psychological symptoms at 3- and 12-month follow-up using Post-Traumatic Stress Syndrome-14 for post-traumatic stress disorder; Depression, Anxiety Stress Scales-21 for depression, anxiety, and stress. Secondary outcomes: HRQOL, using EuroQol-5D-5L questionnaire.

Results

Of the 133 ICU survivors, 54/116 (47 %) had at least one clinically significant psychological symptom (i.e., post-traumatic stress disorder, anxiety, depression, stress) at follow-up. Clinically significant scores for psychological symptoms were observed in 26 (39 %) versus 16 (32 %) at 3-months [odds ratio 1.4, 95 % confidence interval (0.66-3.13), p = 0.38]; 23 (37 %) versus 10 (31 %) at 12-months [odds ratio 1.3, 95 % confidence interval (0.53-3.31), p = 0.57] of intubated versus non-intubated survivors, respectively. Usual activities and mobility were the most commonly affected HRQOL dimension, with >30 % at 3 versus months and >20 % at 12-months of overall survivors reporting ≥ moderate problems. There was no difference between the groups in any of the EQ5D dimensions.

Conclusions

Nearly one-in-two (47 %) of the intubated and non-intubated ICU survivors reported clinically significant psychological symptoms at 3 and 12-month follow-ups. Overall, more than 30 % at 3-months and over 20 % at 12-months of the survivors in both groups had moderate or worse problems with their usual activities and mobility. The presence of psychological symptoms and HRQOL impairments was similar between the groups.

Turkish translation, cross-cultural adaptation, and assessment of psychometric properties of the Ottawa sitting scale for the intensive care unit survivors

PURPOSE

To translate and cross-culturally adapt the Ottawa Sitting Scale (OSS) developed for acute care patients into Turkish and to examine its psychometric properties in intensive care unit (ICU) survivors.

METHODS

After translation process the Turkish version of the scale was adminstered to eighty-one patients aged 39-82 years after discharge from the ICU and videotape was recorded. Two physiotherapists watched the videotaped records during the evaluation and scored. Test-retest reliability was assesed by scoring the same video recordings 15 days after the initial scoring. Correlations of the OSS with Berg Balance Scale (BBS), Functional Independence Measurement (FIM), the ICU length of stay and, total mechanical ventilation duration were assessed for convergent validity.

RESULTS

The intra-class correlation coefficient for inter and intra-rater reliability was 0.989-0.994 and 0.998 respectively. The internal consistency was excellent (Cronbach's α = 0.998). The OSS score was highly correlated with the BBS total score (r = 0.716), the BBS unsupported sitting item score (r = 0.863), and moderately correlated with the total score of the FIM (r = 0.602), the number of days in ICU (r= -0.545), and total mechanical ventilation duration (r = -0.518).

CONCLUSION

The Turkish version of OSS has been found to be valid and reliable in assessment of sitting balance in patients discharged from intensive care unit.Implications For RehabilitationPhysiotherapeutic measurements are crucial and necessary to determine the functional status of the patients.Ottawa Sitting Scale was translated and culturally adapted to Turkish and showed good psychometric propertiesOttawa Sitting Scale is valid and reliable tool to evaluate sitting balance in intensive care unit survivors.Ottawa Sitting Scale can guide clinicians in establishing evaluation and rehabilitation programs for patients discharged from intensive care unit.

Reduced quality of life in ICU survivors - the story behind the numbers: A mixed methods study

PURPOSE

To gain insight into the daily functioning of ICU survivors who reported a reduced quality of life (QoL) one year after ICU admission.

MATERIALS AND METHODS

A two-phase mixed method study design. QoL was assessed using the SF-36 questionnaire before admission and after one year (Phase 1). Participants reporting a reduced QoL were invited for an in-depth interview (Phase 2). Interview data were coded thematically using the PROMIS framework.

RESULTS

Of the 797 participants, 173 (22%) reported a reduced QoL, of which 19 purposively selected patients were interviewed. In line with their questionnaire scores, most participants described their QoL as reduced. They suffered from physical, mental and/or cognitive problems, impacting their daily life, restricting hobbies, work, and social activities. A new balance in life, including relationships, had to be found. Some interviewees experienced no changes in their QoL; they were grateful for being alive, set new life priorities, and were able to accept their life with its limitations.

CONCLUSIONS

Reduction in QoL is due to physical, mental, and cognitive health problems, restricting participants what they want to do. However, QoL was not only affected by the critical illness, but also by factors including independency, comorbidity, and life events. Registration: NCT03246334 (clinical trials.gov).

Changes in health-related quality of life after discharge from an intensive care unit: a systematic review

Quality of life after critical illness is becoming increasingly important as survival improves. Various measures have been used to study the quality of life of patients discharged from intensive care. We systematically reviewed validated measures of quality of life and their results. We searched PubMed, CENTRAL, CINAHL, Web of Science and Open Grey for studies of quality of life, measured after discharge from intensive care. We categorised studied populations as: general; restricted to level-3 care or critical care beyond 5 days; and septic patients. We included quality of life measured at any time after hospital discharge. We identified 48 studies. Thirty-one studies used the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) and 19 used the EuroQol-5D (EQ-5D); eight used both and nine used alternative validated measures. Follow-up rates ranged from 26-100%. Quality of life after critical care was worse than for age- and sex-matched populations. Quality of life improved for one year after hospital discharge. The aspects of life that improved most were physical function, physical role, vitality and social function. However, these domains were also the least likely to recover to population norms as they were more profoundly affected by critical illness.

Factors associated with venous thromboembolic events following ICU admission in patients undergoing spinal surgery: an analysis of 1269 consecutive patients

In BriefIn a retrospective study the authors examined 1269 patients who underwent spinal surgery and were admitted to the intensive care unit (ICU) and identified factors that are associated with venous thromboembolic events (VTEs) in this "high risk" group. Amongst these high-risk factors were: surgeries longer than 4 hours, comorbid disease, patients needing an osteotomy, and patients undergoing spinal stabilization for fractures. Identification of factors that can be optimized prior to surgery will decrease the rates of VTE.

Health-related quality of life in intensive care survivors: Associations with social support, comorbidity, and pain interference

BACKGROUND

Experiences during a stay in the intensive care unit (ICU), including pain, delirium, physical deterioration, and the critical illness itself, may all influence survivors' health-related quality of life (HRQOL). However, few studies have examined the influence of social support, comorbidity, and pain interference on ICU survivors' HRQOL.

OBJECTIVES

To investigate possible associations between social support, number of comorbidities, and pain interference on HRQOL in ICU survivors.

METHODS

ICU survivors responded to a survey 3 months (n = 118) and 1 year (n = 89) after ICU discharge. HRQOL was measured using the Short Form Health Survey-12 (v1), social support using the revised Social Provision Scale, pain interference using the Brief Pain Inventory-Short Form, and comorbidities using the Self-Administered Comorbidity Questionnaire.

RESULTS

Physical and mental HRQOL were reduced at both 3 months and 1 year in ICU survivors compared with the general population. This reduction was more pronounced at 3 months for physical HRQOL, while a small reduction in mental HRQOL was not clinically relevant. Social support was statistical significantly positively associated with mental HRQOL at 3 months, while number of comorbidities was statistical significantly associated with a reduction in physical HRQOL at 3 months and 1 year and mental HRQOL at 1 year. Lastly pain interference was significantly associated with a reduction in physical HRQOL at 3 months and 1 year.

CONCLUSIONS

ICU survivors primarily report reduced physical HRQOL. Social support was positively associated with mental HRQOL, while number of comorbidities, and pain interference were all significantly associated with a reduction in HRQOL. Pain interference was associated with the largest reduction in HRQOL.

Changes in health-related quality of life (HRQoL) after discharge from intensive care unit: a protocol for a systematic review

INTRODUCTION

Treatment on an intensive care unit (ICU) imposes a high treatment burden on patients, as well as an economic burden for the healthcare provider. Many studies have recorded health-related quality of life (HRQoL) in patients after treatment on an ICU. We propose a systematic review of these studies.

METHODS

We will search the National Library of Medicine's PubMed electronic database (PubMed), the Cochrane database, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Science and Open Grey to identify papers reporting quality of life after discharge from ICU. We will include papers including validated quality of life measures. We will examine three categories: populations of patients treated on general ICUs, patients with severe infections and patients with respiratory dysfunction. We will extract HRQoL data. We will assess papers for risk of bias using the QUADAS-2 tool. The strength of our conclusions will depend on the quality and number of papers showing uniform results.

ETHICS AND DISSEMINATION

This review will use published literature and contains no primary data; so we do not need ethical approval. We will submit the outcome of the systematic review to a peer-reviewed journal.

Rehabilitation activities, out-patient visits and employment in patients and partners the first year after ICU: a descriptive study

OBJECTIVES

To describe the influence of critical illness on patients and their partners in relation to rehabilitation, healthcare consumption and employment during the first year after Intensive Care Unit discharge.

DESIGN

Longitudinal, observational and descriptive.

SETTING

Five Danish Intensive Care Units.

METHODS

Data were collected from hospital charts, population registers and interviews with 18 patients and their partners at 3 and 12 months after intensive care discharge. Descriptive statistical analysis was performed.

RESULTS

Post-discharge inpatient rehabilitation was median (range) 52 (15-174) days (n=10). Community-based training was 12 (3-34) weeks (n=15). Neuropsychological rehabilitation following brain damage was 13-20 weeks (n=3). Number of out-patient visits 1 year before and 1 year after were mean 3 versus 8, and General Practitioner visits were 12 versus 18. Three patients resumed work at pre-hospitalisation employment rates after 12 months. After the patients' stay in intensive care, partners' mean full-time sick leave was 17 (range 0-124) days and 21 (range 0-106) days part time. Partners often had long commutes.

CONCLUSION

Most patients had comprehensive recovery needs requiring months of rehabilitation. Some partners needed extensive sick leave. The study reveals the human cost of critical illness and intensive care for patients and partners in the Danish welfare system.

Quality of life before intensive care using EQ-5D: patient versus proxy responses

OBJECTIVE

To compare patients' retrospectively reported baseline quality of life before intensive care hospitalization with population norms and proxy reports.

DESIGN

Prospective cohort study.

SETTING

Thirteen ICUs at four teaching hospitals in Baltimore, MD.

PATIENTS

One hundred forty acute lung injury survivors and their designated proxies.

INTERVENTIONS

Around the time of hospital discharge, both patients and proxies were asked to retrospectively estimate patients' baseline quality of life before hospital admission using the EQ-5D quality-of-life instrument.

MEASUREMENTS AND MAIN RESULTS

Mean patient-rated EQ-5D visual analog scale scores and utility scores were significantly lower than population norms but were significantly higher than proxy ratings. However, the magnitude of difference in average utility scores between patients and either population norms or proxies was not clinically important. For the five individual EQ-5D domains, κ statistics revealed slight to fair agreement between patients and proxies. Bland-Altman plots demonstrated that for both the visual analog scale and utility scores, proxies underestimated scores when patients reported high ratings and overestimated scores for low patient ratings.

CONCLUSIONS

Patients retrospectively reported worse baseline health status before acute lung injury than population norms and better status than proxy reports; however, the magnitude of these differences in health status may not be clinically important. Proxies had only slight to fair agreement with patients in all five EQ-5D domains, attenuating patients' more extreme ratings toward moderate scores. Caution is required when interpreting proxy retrospective reports of baseline health status for survivors of acute lung injury.

Quality of life after intensive care: a systematic review of the literature

OBJECTIVES

To evaluate quality of life at least 12 months after discharge from the intensive care unit of adult critically ill patients, to evaluate the methodology used to assess long-term quality of life, and to give an overview of factors influencing quality of life.

DATA SOURCES

EMBASE-PubMed, MEDLINE (OVID), SCI/Web of Science, the Cochrane Library, Google Scholar, and personal files.

DATA EXTRACTION

Data extraction was performed independently and cross-checked by two reviewers using a predefined data extraction form. Eligible studies were published between 1999 and 2009 and assessed quality of life ≥12 months after intensive care unit discharge by means of the Medical Outcomes Study 36-Item Short Form Health Survey, the RAND 36-Item Health Survey, EuroQol-5D, and/or the Nottingham Health Profile in adult intensive care unit patients.

DATA SYNTHESIS

Fifty-three articles (10 multicenters) were included, with the majority of studies performed in Europe (68%). The Medical Outcomes Study 36-Item Short Form Health Survey was used in 55%, and the EuroQol-5D, the Nottingham Health Profile, the RAND 36-Item Health Survey, or a combination was used in 21%, 9%, 8%, or 8%, respectively. A response rate of ≥80% was attained in 26 studies (49%). Critically ill patients had a lower quality of life than an age- and gender-matched population, but quality of life tended to improve over years. The worst reductions in quality of life were seen in cases of severe acute respiratory distress syndrome, prolonged mechanical ventilation, severe trauma, and severe sepsis. Study quality criteria, defined as a baseline quality of life assessment, the absence of major exclusion criteria, a description of nonresponders, and a comparison with a reference population were met in only four studies (8%). Results concerning the influence of severity of illness, comorbidity, preadmission quality of life, age, gender, or acquired complications were conflicting.

CONCLUSIONS

Quality of life differed on diagnostic category but, overall, critically ill patients had a lower quality of life than an age- and gender-matched population. A minority of studies met the predefined methodologic quality criteria. Results concerning the influence of the patients' characteristics and illnesses on long-term quality of life were conflicting.

Patients' recovery after critical illness at early follow-up

AIM

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

BACKGROUND

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

DESIGN

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

RELEVANCE TO CLINICAL PRACTICE

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

Baseline quality of life before intensive care: a comparison of patient versus proxy responses

OBJECTIVE

To compare acute lung injury patients' self-reported, retrospective baseline quality of life before their intensive care hospitalization with population norms and retrospective proxy estimates.

DESIGN

Prospective cohort study using the Short Form 36 quality-of-life survey.

SETTING

Thirteen intensive care units at four teaching hospitals in Baltimore, Maryland.

PATIENTS

One hundred thirty-six acute lung injury survivors and their designated proxies.

INTERVENTIONS

Both patients and proxies were asked to estimate patient baseline quality of life before hospital admission using the Short Form 36 survey.

MEASUREMENTS AND MAIN RESULTS

Compared with population norms, quality-of-life scores were lower in acute lung injury patients across all eight domains, but the difference was significantly greater than the minimum clinically important difference in only two of eight domains (Physical Role and General Health). The mean paired difference between patient and proxy responses revealed no clinically important difference. However, kappa statistics demonstrated only fair to moderate agreement for all domains. Bland-Altman analysis revealed that, for all domains, proxies tended to overestimate quality of life when patient scores were low and underestimate the quality of life when patient scores were high.

CONCLUSION

Retrospective assessment of quality of life before hospitalization revealed that acute lung injury patients' scores were consistently lower than population norms, but the magnitude of this difference may not be clinically important. Proxy assessments had only fair to moderate agreement with patient assessments. Across all eight Short Form 36 quality-of-life domains, proxy responses represented an attenuation of patient quality-of-life estimates.

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.

Physical Rehabilitation following Critical Illness

The effects of critical illness and associated significant periods of immobility often result in patients requiring lengthy periods of rehabilitation. Patients frequently have diminished cardiac and respiratory reserve, together with generally decreased muscle strength and endurance. Myopathies and neuropathies are sometimes evident, and patients are frequently unable to carry out simple functional tasks.

Although the need for physical rehabilitation is well established, substantive evidence to guide rehabilitation services is lacking. Research has been conducted to establish safe commencement of mobilisation, and expert opinion is that there is a generally accepted hierarchy of mobilisation techniques. As well as progressively increasing mobility, there are also suggestions that specific exercise programmes can influence weaning time and length of stay. Post discharge, evidence suggests that there is a need for on-going rehabilitation, and early research shows encouraging results. However, many questions remain unanswered. More evidence is required in order to establish what the best practice is for acute rehabilitation and for rehabilitation as part of follow-up care.

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.

Devenir et qualité de vie d'une population âgée de plus de 80 ans trois mois après un séjour en réanimation

OBJECTIVES

The aging of the population has seen an increase in the number of elderly patients admitted to reanimation units. We sought to know the outcomes and evolution of the quality of life of a population of elderly patients after their experience with this type of service.

METHOD

We included all patients older than 80 years who had been in two intensive care units in the Loire region of France between October 2005 and May 2006. We studied their state of mind 3 months after they exited the service. Then, for the survivors, we used the Activities of Daily Living (ADL) scale and the generic questionnaire of health, the SF-36, to evaluate the evolution of their degree of autonomy and quality of life related to health compared to that one month prior to entry in the reanimation unit.

RESULTS

We included 70 patients (mean age 85.2+/-4.5 years). At 3 months after exiting reanimation, the survival rate was 57%, and 28 survivors underwent rating scale testing. The physical score of the SF-36 and the ADL score were significantly decreased as compared with that one-month before admission, with no significant difference in mental score of the SF-36. Physical deterioration did not have a significant effect on the evolution of perceived health (dimension GH of the SF-36), life and relations with others (dimension SF) or mental health (dimension MH). The decreased ADL score was correlated with that of the two physical dimensions of the SF-36, with no correlation with the four psychic dimensions. A total of 92% of patients were satisfied with their care in reanimation and three of four would agree to go back if their state required it. For the others, it is a question of respecting the will of the elderly patients confronted with reanimation care.

CONCLUSION

Three months after intensive care with reanimation, elderly patients do not have significantly modified perceived health and psychic state as compared with objective deteriorated physical capacity. The absence of consensus on the threshold of old age and the quality-of-life instrument to use prevents a comparison of our results with those in the literature. However, others have shown and we agree that elderly people could benefit from reanimation therapy.

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.

Role of preexisting disease in patients' perceptions of health-related quality of life after intensive care

OBJECTIVES

To find out how patients perceive their health-related quality of life after they have been treated in an intensive care unit and whether preexisting disease influenced their perception.

DESIGN

: Follow-up, quantitative, dual-site study.

SETTING

Combined medical and surgical intensive care units of one university and one general hospital in Sweden.

PATIENTS

Among the 1,938 patients admitted, 562 were considered eligible (>24 hrs in the intensive care unit, and age >18 yrs). The effect of preexisting disease was assessed by use of a large reference group, a random sample (n = 10,000) of the main intake area of the hospitals.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

During 2000-2002, data were collected from the intensive care unit register and from a questionnaire mailed to the patients 6 months after their discharge from hospital. Subjects in the reference group were sent postal questionnaires during 1999. Of the patients in the intensive care unit group, 74% had preexisting diseases compared with 51% in the reference group. Six months after discharge, health-related quality of life was significantly lower among patients than in the reference group. When comparisons were restricted to the previously healthy people in both groups, the observed differences were about halved, and when we compared the patients in the intensive care unit who had preexisting diseases with subjects in the reference group who had similar diseases, we found little difference in perceived health-related quality of life. In some dimensions of health-related quality of life, we found no differences between patients in the intensive care unit and the subjects in the reference population.

CONCLUSIONS

Preexisting diseases significantly affect the extent of the decline of health-related quality of life after critical care, and this effect may have been underestimated in the past. As most patients who are admitted to an intensive care unit have at least one preexisting disease, it is important to account for these effects when examining outcome.

Outcomes of Elderly Survivors of Intensive Care

An increasing proportion of critically ill patients are elderly (ie, >or= 65 years of age). This poses complex challenges and choices for the management of elderly patients. Outcome following admission to the ICU has been traditionally concerned with mortality. Beyond mortality, outcomes such as functional status and health-related quality of life (HRQOL) have assumed greater importance. This article reviews the literature, published in English from 1990 to December 2003, pertaining to HRQOL and functional status outcomes of elderly patients. Functional status and HRQOL of elderly survivors of ICUs has been underinvestigated. There is no agreement as to the optimal instrument choice, and differences between studies preclude meaningful comparison or pooling of results.

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.

Quality of life in adult survivors of critical illness: a systematic review of the literature

OBJECTIVE

To determine how the quality of life (QOL) of intensive care unit (ICU) survivors compares with the general population, changes over time, and is predicted by baseline characteristics.

DESIGN

Systematic literature review including MEDLINE, EMBASE, CINAHL and Cochrane Library. Eligible studies measured QOL > or = 30 days after ICU discharge using the Medical Outcomes Study 36-item Short Form (SF-36), EuroQol-5D, Sickness Impact Profile, or Nottingham Health Profile in representative populations of adult ICU survivors. Disease-specific studies were excluded.

MEASUREMENTS AND RESULTS

Of 8,894 citations identified, 21 independent studies with 7,320 patients were reviewed. Three of three studies found that ICU survivors had significantly lower QOL prior to admission than did a matched general population. During post-discharge follow-up, ICU survivors had significantly lower QOL scores than the general population in each SF-36 domain (except bodily pain) in at least four of seven studies. Over 1-12 months of follow-up, at least two of four studies found clinically meaningful improvement in each SF-36 domain except mental health and general health perceptions. A majority of studies found that age and severity of illness predicted physical functioning.

CONCLUSIONS

Compared with the general population, ICU survivors report lower QOL prior to ICU admission. After hospital discharge, QOL in ICU survivors improves but remains lower than general population levels. Age and severity of illness are predictors of physical functioning. This systematic review provides a general understanding of QOL following critical illness and can serve as a standard of comparison for QOL studies in specific ICU subpopulations.

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.

Returning home after intensive care: a comparison of symptoms of anxiety and depression in ICU and elective cardiac surgery patients and their relatives

OBJECTIVE

This study gathered data on symptoms of anxiety and depression in patients and relatives after discharge from intensive care and examined whether the intensive care population differ from an elective cardiac surgery group with regards to their anxiety and depression symptom reporting.

DESIGN AND SETTING

A single measurement point matched group comparison study in an ICU follow-up programme.

PATIENTS AND PARTICIPANTS

Twenty ICU patients and their relatives and a matched comparison group of 15 elective cardiac surgery patients and their relatives.

MEASUREMENTS AND RESULTS

Patients and relatives completed the Hospital Anxiety and Depression Scale. Relatives answered an open question to explore the perceived impact of Intensive care/cardiac surgery on their lives. ICU patients' relatives reported significantly higher number of symptoms of anxiety than did ICU patients, higher number of symptoms of depression than cardiac surgery patients' relatives, and more troubling and life-altering experiences than the relatives of cardiac surgery patients.

CONCLUSIONS

Relatives of ICU patients also suffer anxiety and depression, and services should address this need. Group differences suggest that ICU patients' relatives have "unique" characteristics of depression symptom reporting.

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.

Following the path of ICU survivors: a quality-improvement activity

Recent interest in continuity of care has meant that the illness trajectory experienced by intensive care unit (ICU) patients has received more attention. Using continuous quality improvement as a framework, this paper describes information obtained during a 3-year period relating to ICU patients' long-term experiences after being discharged from hospital. This information identified that most participants had been discharged home but that many experienced problems with mobility, disability and fatigue. Changes in employment status and the need for financial assistance were noted. As a result of the information provided by this activity, clinical practice has changed and a number of formal research studies have been undertaken.

Will he get back to normal? Survival and functional status after intensive care therapy

The study aim was to address healthcare workers' and patients' questions about the likely level of recovery at 6 months of patients admitted to an Australian intensive care unit (ICU). Ninety-three consecutive, eligible adults were identified and followed prospectively. Severity of illness on admission was assessed using Acute Physiological and Chronic Health Evaluation (APACHE II), while functional status at 6 months was evaluated using the Sickness Impact Profile (SIP). Cumulative mortality was 25%. Admission severity of illness was associated with survival at 6 months (P < or = 0.001). Fifty-one (78%) of the 70 survivors were interviewed. Admission severity of illness scores correlated with functional status at 6 months (r = 0.34, P = 0.01), a finding reported in only one other study. More than half of those interviewed had returned to near pre-admission functional status. Those with poor functional status included high proportions of people with chronic illness and head injury. Overall, physical recovery was more complete than psychosocial recovery. The findings provide useful information for addressing questions relating to physical and psychosocial recovery, appetite, sleep patterns and return to work post discharge.

Health status of ICU survivors: a pilot study

This paper reports on a pilot study that focused on the feasibility of conducting longitudinal research on the health status of intensive care unit (ICU) survivors. Twenty patients completed a short ICU specific health status survey while in ICU and then were invited to complete the same survey--with the addition of the Medical Outcome Study Short Form-36 (SF-36) health status survey--at 6 and 12 months after their hospital discharge. While the patients were in the ICU, 20 family members completed the same survey on the patients' behalf as proxy respondents. Most patients were willing to be in the study for its duration. There was a wide variation in patients' responses to the ICU specific instrument at all data collection points. Patient and proxy responses were very similar for almost all of the physical items but there was a lack of agreement for the more subjective psychosocial items. The SF-36 was found to be more reliable and easier to score and analyse in this small study than the ICU specific health status instrument. The three SF-36 scales ranked lowest at 6 months were physical functioning, role-physical and role-emotional, while at 12 months the three lowest were role-physical, role-emotional and vitality. Total attrition at 12 months was 40 per cent. Using the results of the SF-36, sample size estimates were conducted in preparation for a larger study. It was concluded that it is feasible to conduct longitudinal research on ICU survivors but proxy responses should not be used indiscriminately.
