Health-related quality of life of patients with multiple organ dysfunction: individual changes and comparison with normative population

Factors associated with employment outcome after critical illness: Systematic review, meta-analysis, and meta-regression

AIMS

To synthesize data on prevalence and risk factors for return to work (RTW) in ICU survivors.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

PUBMED, CINAHL, EMBASE and PsycINFO databases were searched from 2000-Feb 2020.

REVIEW METHODS

Peer-reviewed articles that included adult ICU survivors and employment outcomes. Two investigators independently reviewed articles following the PRISMA protocol. Pooled prevalence for RTW was calculated. Meta-regression analyses were performed to assess the association between disability policies, temporal factors and RTW following ICU.

RESULTS

Twenty-eight studies (N = 8,168) met the inclusion criteria. All studies were scored as 'low risk of bias'. Using meta-analysis, the proportion (95% CI) of RTW following ICU was 29% (0.20,0.42), 59% (0.50,0.70), 56% (0.50,0.62), 63% (0.54,0.72), 58% (0.37,0.91), 58% (0.42,0.81), and 44% (0.25,0.76) at 3, 4-6, 7-12, 13-24, 25-36, 37-48, and 49-60 months, respectively. Time and disability policy support are factors associated with the proportion of ICU survivors who RTW. Through meta-regression, there is a 20% increase (95% CI: 0.06, 0.33) in the proportion of individuals who RTW per year. However, the average rate of increase slows by 4% (-0.07, -0.1) per year. In countries with high support policies, the proportion of RTW is 32% higher compared with countries with low support policies (0.08, 0.24). However, as subsequent years pass, the additional proportion of individuals RTW in high support countries declines (β = -0.06, CI: -0.1, -0.02).

CONCLUSIONS

Unemployment is common in ICU survivors. Countries with policies that give higher support for disabled workers have a higher RTW proportion to 3 years following ICU admission. However, from 3-5 years, there is a shift to countries with lower support policies having better employment outcomes.

IMPACT

Health care policies have an impact on RTW rate in survivors of ICU. Healthcare providers, including nurses, can function as public advocates to facilitate policy change.

Impact of Critical Illness on Quality of Life after Intensive Care Unit Discharge

Objective

To assess the quality of life (QoL) following intensive care unit (ICU) discharge using 6 months’ prospective follow-up and to analyze the risk factors affecting quality-of-life post-discharge.

Design

A prospective observational cohort study. Conducted on adult patients, discharged from ICU after more than 7 days’ stay. Study duration is from January 2017 to October 2018. Patients <18 years, nonconsenting, preexisting neurological illness, and lost to follow-up were excluded. Follow-up was done at 1 and 6 months using the SF-36 questionnaire. The pre-ICU functional status, patient demographics, sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation (APACHE II) score, New York Health Evaluation (NYHA) classification, and details of ICU stay were collected.

Results

One hundred patients (M = 60, F = 40) with ICU stay (13.64 ± 3.75 days), days of mechanical ventilation (7.93 ± 3.89 days), admission APACHE II (18.88 ± 4.34) and SOFA (7.73 ± 1.54) scores. Comparison showed physical component summary (PCS) score and mental component summary (MCS) score at pre-ICU were 55.12 and 55.09 which decreased to 39.59 and 35.49 (p < 0.05) at 1 month post-discharge and 47.93 and 37.46 at 6 months. Age, APACHE II, and SOFA scores are the significant factors affecting PCS and MCS. Length of ICU stay and duration of mechanical ventilation did not affect significantly at 6 months. When compared with general population PCS and MCS showed significant deterioration at 1 and 6 months.

Conclusion

Post-ICU discharge patients have significant functional impairment and compromised health-related QoL (HRQoL). Age and severity of illness significantly affects health quality parameters and decline is below the normal data of general population.

Return to work after critical illness: a systematic review and meta-analysis

BACKGROUND

Survivors of critical illness often experience poor outcomes after hospitalisation, including delayed return to work, which carries substantial economic consequences.

OBJECTIVE

To conduct a systematic review and meta-analysis of return to work after critical illness.

METHODS

We searched PubMed, Embase, PsycINFO, CINAHL and Cochrane Library from 1970 to February 2018. Data were extracted, in duplicate, and random-effects meta-regression used to obtain pooled estimates.

RESULTS

Fifty-two studies evaluated return to work in 10 015 previously employed survivors of critical illness, over a median (IQR) follow-up of 12 (6.25-38.5) months. By 1-3, 12 and 42-60 months' follow-up, pooled return to work prevalence (95% CI) was 36% (23% to 49%), 60% (50% to 69%) and 68% (51% to 85%), respectively (τ ²=0.55, I²=87%, p=0.03). No significant difference was observed based on diagnosis (acute respiratory distress syndrome (ARDS) vs non-ARDS) or region (Europe vs North America vs Australia/New Zealand), but was observed when comparing mode of employment evaluation (in-person vs telephone vs mail). Following return to work, 20%-36% of survivors experienced job loss, 17%-66% occupation change and 5%-84% worsening employment status (eg, fewer work hours). Potential risk factors for delayed return to work include pre-existing comorbidities and post-hospital impairments (eg, mental health).

CONCLUSION

Approximately two-thirds, two-fifths and one-third of previously employed intensive care unit survivors are jobless up to 3, 12 and 60 months following hospital discharge. Survivors returning to work often experience job loss, occupation change or worse employment status. Interventions should be designed and evaluated to reduce the burden of this common and important problem for survivors of critical illness.

An Early Tailored Approach Is the Key to Effective Rehabilitation in the Intensive Care Unit

OBJECTIVE

To investigate the effectiveness, feasibility, and safety of an evidence-based rehabilitation care pathway in the intensive care unit (ICU) in different patient populations.

DESIGN

Observational prospective cohort study, with retrospective controls.

SETTING

ICUs of a university hospital.

PARTICIPANTS

Patients admitted between April 1, 2015, and June 30, 2015, were compared to a retrospective cohort admitted to the same ICUs during the same 3-month period in 2014. The number of patients studied (N=285) included 152 in the prospective group and 133 in the retrospective group.

INTERVENTIONS

The prospective cohort benefited of a rehabilitation care pathway based on (1) interdisciplinary teamwork; (2) early customized and goal-oriented rehabilitation; (3) daily functional monitoring and treatment revision; (4) agreed discharge policy; and (5) continuity of care. The retrospective cohort underwent usual care.

MAIN OUTCOME MEASURES

Included the following: (1) proportions of patients undergoing rehabilitation team evaluation; (2) latency between patient admission to ICUs and rehabilitation team assessment; (3) proportions of patients undergoing rehabilitation treatment during ICU stay; (4) latency between the patient admission to ICUs and rehabilitation start; (5) ICU stay and total acute hospital stay; and (5) proportion of ventilator-free days out of ICU stay.

RESULTS

The novel rehabilitation care pathway led to (1) an increased proportion of patients receiving rehabilitative assessment (P<.0001); (2) a decreased latency from ICU admission to both rehabilitation team assessment and rehabilitation start (P<.0001); (3) an increased proportion of patients undergoing rehabilitation (P<.0001); (4) a shorter length of stay in ICUs (P<.0001) and in hospital (P=.047); and (5) a shorter mechanical ventilation duration (P<.02). A direct relationship between rehabilitation start latency and ICU length of stay was observed.

CONCLUSIONS

An early, interdisciplinary team approach, providing a customized dynamic planning of physiotherapy programs, increases ventilator-free time and reduces total hospital stay, especially in patients admitted to the ICU after general surgery. This rehabilitation care pathway can be generalized to different geopolitical scenarios, being feasible, safe and cost effective.

Factors associated with missed assessments in a 2-year longitudinal study of acute respiratory distress syndrome survivors

Background

To evaluate participant-related variables associated with missing assessment(s) at follow-up visits during a longitudinal research study.

Methods

This is a prospective, longitudinal, multi-site study of 196 acute respiratory distress syndrome (ARDS) survivors. More than 30 relevant sociodemographic, physical status, and mental health variables (representing participant characteristics prior to ARDS, at hospital discharge, and at the immediately preceding follow-up visit) were evaluated for association with missed assessments at 3, 6, 12, and 24-month follow-up visits (89–95% retention rates), using binomial logistic regression.

Results

Most participants were male (56%), white (58%), and ≤ high school education (64%). Sociodemographic characteristics were not associated with missed assessments at the initial 3-month visit or subsequent visits. The number of dependencies in Activities of Daily Living (ADLs) at hospital discharge was associated with higher odds of missed assessments at the initial visit (OR: 1.26, 95% CI: 1.12, 1.43). At subsequent 6-, 12-, and 24 months visits, post-hospital discharge physical and psychological status were not associated with subsequent missed assessments. Instead, the following were associated with lower odds of missed assessments: indicators of poorer health prior to hospital admission (inability to walk 5 min (OR: 0.46; 0.23, 0.91), unemployment due to health (OR: 0.47; 0.23, 0.96), and alcohol abuse (OR: 0.53; 0.28, 0.97)) and having the preceding visit at the research clinic rather than at home/facility, or by phone/mail (OR: 0.54; 0.31, 0.96). Inversely, variables associated with higher odds of missed assessments at subsequent visits include: functional dependency prior to hospital admission (i.e. dependency with > = 2 Instrumental Activities of Daily Living (IADLs) (OR: 1.96; 1.08, 3.52), and missing assessments at preceding visit (OR: 2.26; 1.35, 3.79).

Conclusions

During the recovery process after hospital discharge, dependencies in physical functioning (e.g. ADLs, IADLs) prior to hospitalization and at hospital discharge were associated with higher odds of missed assessments. Conversely, other indicators of poorer health at baseline were associated with lower odds of missed assessments after the initial post-discharge visit. To reduce missing assessments, longitudinal clinical research studies may benefit from focusing additional resources on participants with dependencies in physical functioning prior to hospitalization and at hospital discharge.

Health-related quality of life after general surgical intensive care

BACKGROUND

Impaired mental and physical health are common complications after intensive care that could influence the patient's health-related quality of life (HRQoL). Earlier research has mainly focused on HRQoL in mixed surgical and medical ICU populations. This study aimed to describe and analyze factors associated with HROoL after discharge from a general surgical ICU.

METHODS

A prospective cohort study was conducted in a general surgical ICU in Sweden between 2005 and 2012. Adult patients (≥18 years) with an ICU length of stay ≥96 hours were included. HRQoL was measured at 3, 6, and 12 months after discharge from the ICU using a questionnaire (SF-36). A linear mixed model was used to analyze changes over time and Wilcoxon Signed Rank Tests were used to compare the 12-months results to an age and gender matched reference population in Sweden. Linear regression analyses were performed to explore the impact on HRQoL from background variables.

RESULTS

Of 447 patients eligible for the study, 276 patients (62%) answered SF-36 at least once at 3, 6 or 12 months after ICU care and were included in the study. HRQoL improved over time but was still significantly lower at 12 months compared to the reference population. Female gender, age <75 years, living single, and ICU-stay of more than 14 days were associated with lower HRQoL.

CONCLUSION

General surgical ICU patients reports low HRQoL 1 year after ICU stay. The impaired HRQoL could be a long-lasting problem with major consequences for the individual, family, and society.

Organ support therapy in the intensive care unit and return to work: a nationwide, register-based cohort study

PURPOSE

The association between severity of illness and ability to return to work is unclear. Therefore, we investigated return to work and associations with measures of illness severity in ICU survivors.

METHODS

We conducted this cohort study using Danish registry data for the period 2005-2014 on ICU patients who were discharged alive from hospital, had an ICU length of stay (LOS) of at least 72 h, were not treated with dialysis before hospital admission and were working prior to admission. We assessed (1) the cumulative incidence (chance) of return to work (2005-2017) and receipt of social benefits after discharge from a hospital stay with ICU admission and (2) the association between organ support therapies (renal replacement therapy, cardiovascular support and mechanical ventilation), and during 2011-2014 SAPS II and ICU LOS, and return to work, using multivariable Cox regression.

RESULTS

Among 5762 ICU survivors, 68% returned to work within 2 years after hospital discharge. Disability and sickness benefits constituted 89% of social benefits among patients not returning to work and 59% among patients withdrawing from work following an initial return to work. Mechanical ventilation (HR 0.70, 95% CI [0.65-0.77]), but not RRT (HR 0.85, 95% CI [0.71-1.02]), cardiovascular support (HR 0.93, 95% CI [0.82-1.07]) and increasing SAPS II, was associated with decreased chance of return to work. Increasing ICU LOS was also associated with a decreased chance of return to work.

CONCLUSIONS

The majority of a nationwide cohort of ICU survivors returned to work. Sick leave and receipt of disability pension were common following ICU admission. Mechanical ventilation and longer ICU LOS were associated with reduced chances of return to work.

Acute Pancreatitis Has a Long-term Deleterious Effect on Physical Health Related Quality of Life

BACKGROUND & AIMS

It is not clear how acute pancreatitis (AP) affects health related quality of life (HRQOL). We aimed to determine the long-term independent effect of AP on physical and mental HRQOL.

METHODS

We analyzed data from 91 patients (mean 52 years of age, 54% women) admitted with AP to the University of Pittsburgh Medical Center from 2011 to 2015 who responded to telephone surveys at a median of 14 months after hospital discharge (interquartile range, 12-16 months). Individuals who did not answer the telephone survey were sent a questionnaire by regular mail. Patients answered questions from the 12-Item Short-Form Survey, and answers were used to calculate mental component summary (MCS) and physical component summary (PCS) scores with norm-based scoring (normal ≥50). HRQOL for these subjects was compared with that of age- and sex-matched individuals without pancreatitis (1:2) identified from the North American Pancreatitis Study. We controlled for other covariates using multivariable regression analysis.

RESULTS

At follow-up, individuals with AP had a significantly lower PCS score (46.2 ± 11.8) than did control subjects (51.1 ± 9.5; P < .01), but a similar MCS score. A 4-point reduction of the PCS was attributed to AP after controlling for sociodemographic factors and medical comorbidities. The only pancreatitis-related factor associated with low PCS score was multisystem organ failure. Presence of abdominal pain, analgesic use, disability, and current smoking at the time of follow-up were also associated with lower PCS scores. Etiology of AP, disease severity (by Revised Atlanta classification), use of nutritional support, and performance of pancreatic interventions did not affect HRQOL at follow-up.

CONCLUSIONS

In a 14-month follow-up of patients hospitalized with AP, we found a meaningful, independent, and deleterious effect of AP in the physical HRQOL of these patients, compared to individuals without AP. Further research is needed to determine the duration of this impairment and to evaluate the effects of modifying risk factors.

[Health-related quality of life after mechanical ventilation in the intensive care unit]

BACKGROUND

It is unknown whether health related quality of life measured in German patients one year after mechanical ventilation in the intensive care unit is impaired or not.

OBJECTIVES

The aim of this study was to assess health related quality of life one year after inclusion into a randomized controlled trial for weaning from mechanical ventilation with the help of a questionnaire that has never been used in critically ill patients and to investigate whether health related quality of life scores differ between the study population and a general German population.

METHODS

We followed up with patients one year after inclusion into a randomized control trial investigating the effect of SmartCare/PS on total ventilation time compared to protocol-driven weaning (ASOPI trial, clinicaltrials.gov ID00445289). Health related quality of life was measured using the quality of life questionnaire C‑30 version 3.0 from the European Organization of Research and Treatment of Cancer (EORTC). Mean differences of at least 10 score points in the quality of life scales were considered clinically significant.

RESULTS

Of the 232 patients who were alive 90 days after study inclusion, 24 patients died one year after study inclusion and 64 patients were lost to follow-up. Of the remaining145 patients who were successfully contacted, 126 patients agreed to fill out the questionnaire. Questionnaires were sent back to the study site by 83 patients and these were analyzed. Health-related quality of life was significantly lower in five of the six functional scales (physical functioning, role functioning, cognitive functioning, social functioning, global health status) and in eight of the nine symptom scales (fatigue, pain, dyspnea, insomnia, appetite loss, constipation, diarrhea, financial difficulties) compared to the reference values of a German normal population.

CONCLUSIONS

The EORTC QLQ-C30 questionnaire is suitable for the acquisition of the health-related quality of life in formerly critically ill patients. Health-related quality of life is severely impaired after mechanical ventilation in the intensive care unit. Future studies should consider health related quality of life as a possible study endpoint.

The role of memories on health-related quality of life after intensive care unit care: an unforgettable controversy?

Background

Decreased health-related quality of life (HRQoL) is a significant problem after an intensive care stay and is affected by several known factors such as age, sex, and previous health-state. The objective of this study was to assess the association between memory and self-reported perceived HRQoL of patients discharged from the intensive care unit (ICU).

Methods

A prospective, multicenter study involving nine general ICUs in Portugal. All adult patients with a length of stay >48 hours were invited to participate in a 6-month follow-up after ICU discharge by answering a set of structured questionnaires, including EuroQol 5-Dimensions and ICU memory tool.

Results

A total of 313 (52% of the eligible) patients agreed to enter the study. The median age of patients was 60 years old, 58% were males, the median Simplified Acute Physiology Score II (SAPS II) was 38, and the median length of stay was 8 days for ICU and 21 days for total hospital stay. Eighty-nine percent (n=276) of the admissions were emergencies. Seventy-eight percent (n=234) of the patients had memories associated with the ICU stay. Patients with no memories had 2.1 higher chances (P=0.011) of being in the bottom half of the HRQoL score (<0.5 Euro-Qol 5-Dimensions index score). Even after adjusting for pre-admission characteristics, having memories was associated with higher perceived HRQoL (adjusted odds ratio =2.1, P=0.022).

Conclusion

This study suggests that most of the ICU survivors have memories of their ICU stay. For the ICU survivors, having memories of the ICU stay is associated with a higher perceived HRQoL 6 months after ICU discharge.

Risk factors for worsened quality of life in patients on mechanical ventilation. A prospective multicenter study

OBJECTIVE

To identify risk factors for worsened quality of life (QoL) and activities of daily living (ADL) at 3 and 12 months after discharge from the Intensive Care Unit (ICU) in patients on mechanical ventilation (MV).

DESIGN

A prospective, multicentric observational study was made.

SETTING

Three ICUs in Argentina.

PATIENTS

The study included a total of 84 out of 129 mainly clinical patients admitted between 2011-2012 and requiring over 24hours of MV.

INTERVENTIONS

No interventions were carried out.

VARIABLES

Quality of life was assessed with the EQ-5D (version for Argentina), and ADL with the Barthel index.

RESULTS

The EQ-5D and Barthel scores were assessed upon admission to the ICU (baseline) and after three months and one year of follow-up. Comorbidities, delirium, ICU acquired weakness (ICUAW), and medication received were daily assessed during ICU stay. The baseline QoL of the global sample showed a median index of [0.831 (IQR25-75% 0.527-0.931)], versus [0.513 (IQR0.245-0.838)] after three months and [0.850 (IQR0.573-1.00)] after one year. Significant differences were observed compared with QoL in the Argentinean general population [mean 0.880 (CI 0.872-0.888), p<0.001; p<0.001; p0.002]. Individual analysis showed that 67% of the patients had worsened their QoL at three months, while 33% had recovered their QoL. In the multivariate analysis, the variables found to be independent predictors of worsened QoL were a hospital stay ≥21 days [OR 12.57 (2.75-57.47)], age ≥50 years [OR 5.61 (1.27-24.83)], previous poor QoL [OR 0.11 (0.02-0.54)] and persistent ICUAW [OR 8.32 (1.22-56.74)]. Similar results were found for the worsening of ADL.

CONCLUSIONS

Quality of life is altered after critical illness, and its recovery is gradual over time. Age, length of hospital stay, previous QoL and persistent ICUAW seem to be risk factors for worsened QoL.

A randomised controlled trial and cost-effectiveness analysis of high-frequency oscillatory ventilation against conventional artificial ventilation for adults with acute respiratory distress syndrome. The OSCAR (OSCillation in ARDS) study

BACKGROUND

Patients with the acute respiratory distress syndrome (ARDS) require artificial ventilation but this treatment may produce secondary lung damage. High-frequency oscillatory ventilation (HFOV) may reduce this damage.

OBJECTIVES

To determine the clinical benefit and cost-effectiveness of HFOV in patients with ARDS compared with standard mechanical ventilation.

DESIGN

A parallel, randomised, unblinded clinical trial.

SETTING

UK intensive care units.

PARTICIPANTS

Mechanically ventilated patients with a partial pressure of oxygen in arterial blood/fractional concentration of inspired oxygen (P : F) ratio of 26.7 kPa (200 mmHg) or less and an expected duration of ventilation of at least 2 days at recruitment.

INTERVENTIONS

Treatment arm HFOV using a Novalung R100(®) ventilator (Metran Co. Ltd, Saitama, Japan) ventilator until the start of weaning. Control arm Conventional mechanical ventilation using the devices available in the participating centres.

MAIN OUTCOME MEASURES

The primary clinical outcome was all-cause mortality at 30 days after randomisation. The primary health economic outcome was the cost per quality-adjusted life-year (QALY) gained.

RESULTS

One hundred and sixty-six of 398 patients (41.7%) randomised to the HFOV group and 163 of 397 patients (41.1%) randomised to the conventional mechanical ventilation group died within 30 days of randomisation (p = 0.85), for an absolute difference of 0.6% [95% confidence interval (CI) -6.1% to 7.5%]. After adjustment for study centre, sex, Acute Physiology and Chronic Health Evaluation II score, and the initial P : F ratio, the odds ratio for survival in the conventional ventilation group was 1.03 (95% CI 0.75 to 1.40; p = 0.87 logistic regression). Survival analysis showed no difference in the probability of survival up to 12 months after randomisation. The average QALY at 1 year in the HFOV group was 0.302 compared to 0.246. This gives an incremental cost-effectiveness ratio (ICER) for the cost to society per QALY of £88,790 and an ICER for the cost to the NHS per QALY of £ 78,260.

CONCLUSIONS

The use of HFOV had no effect on 30-day mortality in adult patients undergoing mechanical ventilation for ARDS and no economic advantage. We suggest that further research into avoiding ventilator-induced lung injury should concentrate on ventilatory strategies other than HFOV.

The influence of hospitalization or intensive care unit admission on declines in health-related quality of life

RATIONALE

Survivors of critical illness report impaired health-related quality of life (HRQoL) after hospital discharge, but the degree to which these impairments are attributable to critical illness is unknown.

OBJECTIVES

We sought to examine changes in HRQoL associated with an intensive care unit (ICU) stay and the differential association of type of hospitalization (critical illness versus noncritical illness) on changes in HRQoL.

METHODS

We identified 11,243 participants in the Ambulatory Care Quality Improvement Project (a multicenter randomized trial of Veterans conducted March 1997 to August 2000) completing at least two Medical Outcomes Study Short-Form 36 questionnaires over 2 years, and categorized patients by hospitalization status during the interval between measures. We used multiple linear regression with generalized estimating equations for analysis.

MEASUREMENTS AND MAIN RESULTS

Our primary outcome was change in the Physical Component Summary score. Participants requiring hospitalization or ICU admission had significantly worse baseline HRQoL than those not hospitalized (P < 0.001). Compared with patients who were not hospitalized, follow-up Physical Component Summary scores were lower among non-ICU hospitalized patients and ICU patients (adjusted β-coefficient = -1.40 [95% confidence interval, -1.81, -0.99] and adjusted β-coefficient = -1.53 [95% confidence interval, -2.11, -0.95], respectively), with no difference between the two groups (P value = 0.80). Similar results were seen for the Mental Component Summary score and each of the Medical Outcomes Study Short-Form 36 subdomains.

CONCLUSIONS

Prehospital HRQoL is a significant determinant of HRQoL after hospitalization or ICU admission. Hospitalization is associated with increased risk of impairment in HRQoL after discharge, yet the overall magnitude of this reduction is small and similar between non-ICU hospitalized and critically ill patients.

Long-term treated intensive care patients outcomes: the one-year mortality rate, quality of life, health care use and long-term complications as reported by general practitioners

BACKGROUND

The purpose of this study was to determine the one-year mortality rate and its predictors regarding long-term intensive care-treated patients together with their health-related quality of life (HRQL), place of living, healthcare use and long-term complication characteristics after intensive care unit (ICU) discharge.

METHODS

A retrospective cohort study was performed in a 20-bed mixed ICU. The patients that were treated for more than 72 h between 2007 and 2012 were included in this study. The one-year mortality rate was calculated, and the characteristics of the ICU survivors that died within one year after ICU discharge were further analysed. For all patients, the Dutch version of the SF-36 questionnaire was used to assess their current HRQL. The results were compared with a normal population. Additionally, patients were questioned about their place of living, and their general practitioners (GPs) were questioned about the patients' possible long-term complications.

RESULTS

Seven hundred and forty patients were included in this study, and their one-year mortality rate was 28 %, of which half died within the first week after ICU discharge. The one-year mortality rate predictors included age at the time of ICU admission, APACHE IV-predicted mortality score, number of comorbidities and ICU re-admissions. The ICU survivor HRQL was significantly lower compared with the normal population. Half of the patients did not return to their pre-hospital place of living, and numerous possible long-term complications were reported, particularly decreased tolerance, chronic fatigue and processing problems of relatives.

CONCLUSIONS

One-year mortality rate of long-term ICU-treated patient was 28 %, and this was predicted by age, disease severity, comorbidities and ICU re-admissions. The ICU survivors reported a lower HRQL, and a minority of these patients returned home directly after hospital discharge; however, GPs reported numerous possible long-term complications.

Changes in health-related quality of life in older patients one year after an intensive care unit stay

AIMS AND OBJECTIVES

This study investigates health-related quality of life in older patients, over one year following an intensive care unit stay.

BACKGROUND

Health-related quality of life is an important outcome when assessing long-term effectiveness of intensive care treatment, and to assist patients, their relatives and healthcare professionals in making treatment decisions.

DESIGN

Prospective non-randomised longitudinal study.

METHODS

The Short Form Health Survey 36 was administered 1 week after an intensive care stay (retrospective baseline), and after six months and 12 months to the study population and to an age-matched comparison group at recruitment (baseline), and after six months and 12 months. Demographic data, admission diagnosis, length of stay, severity of illness, pain, anxiety, agitation, and intratracheal suctioning, turning and intubation were recorded. Recruitment period: December 2008 to April 2011.

RESULTS

Health-related quality of life of the older patients was significantly lower than the comparison group, both before and after the intensive care unit stay, and showed great individual variability. Within group scores, however, were stable over the year. Both physical and mental health scores were lower for the older patients. Renal failure, cardiac surgery and illness severity were associated with lower physical health scores. Cardiovascular illness, intratracheal suctioning and turning were associated with lower mental health scores.

CONCLUSIONS

Health-related quality of life was lower in older patients than in the age-matched group but remained stable over one year.

RELEVANCE TO CLINICAL PRACTICE

Older patients with severe illnesses, acute renal failure or who have had cardiac surgery, need additional support after hospital discharge due to functional restrictions. Discharge planning should ensure that this support would be provided. Special attention should be given to develop and use methods to reduce distress during routine intensive care interventions such as intratracheal suctioning or turning.

Long-term survival and quality of life after open abdominal aortic aneurysm repair

BACKGROUND

Open repair of abdominal aortic aneurysm (AAA) generally involves postsurgery admission to the intensive care unit (ICU). Few studies have evaluated the impact of surgery for either ruptured or nonruptured AAA (with postoperative ICU treatment) on long-term survival and quality of life. The primary aim of this study was to quantify long-term survival and health-related quality of life (HrQpL) of a cohort of patients undergoing open AAA repair after hospital discharge.

METHODS

Consecutive patients undergoing open elective or acute AAA reconstruction with postoperative admission to the ICU and discharged alive from the hospital during 2009 were identified. Primary outcome measures were 1-year and long-term mortality. The secondary outcome was the HrQoL using the EuroQol-6D (EQ-6D) questionnaire at the end of the follow-up period.

RESULTS

A total of 263 patients were treated and postoperatively discharged alive: 56 had a ruptured AAA (rAAA), 35 a symptomatic AAA, and 172 an asymptomatic AAA. The 1-year mortality after open AAA repair was 8 %. Overall, 39 % of patients died within 10 postoperative years (mean 6.0 ± 2.8 years). Long-term survival of patients with a ruptured or symptomatic aneurysm was similar to that of patients undergoing elective aneurysm repair. Long-term HrQoL of the total study population was worse than that of an age-matched general Dutch population on the EQ-us (range 0-1, difference 0.12). This decrease in HrQoL was mainly seen in mobility, self-care, usual activities, and cognition.

CONCLUSIONS

Ten years after open AAA repair, the overall survival rate was 59 %. Long-term survival and HrQoL were similar for patients with a repaired ruptured or symptomatic aneurysm and those who underwent elective aneurysm repair. There were also no differences in patients with infrarenal versus juxtarenal/suprarenal aneurysms. Surviving patients had a lower HrQoL than the age-matched general Dutch population, especially regarding mobility, self-care, usual activities, and cognition.

Our paper 20 years later: 1-year survival and 6-month quality of life after intensive care

INTRODUCTION

In the early 1990s, the in-hospital mortality rate of intensive care unit (ICU) patients dropped, and interest in the quality of life (QOL) of ICU survivors increased. In 1996, we published a study to investigate 1-year survival after hospital discharge and 6-month QOL after intensive care. Now, we compare our previous results with those reported in the recent literature to appraise any changes, and new knowledge in the area.

RESULTS

The 1-year survival of ICU patients after hospital discharge is substantial, lower than in the general population, and different among subgroups. Some studies showed a reduction in QOL at 6 months, as in our study, while others showed an improvement. Different results seem to be related mainly to the case mix. Studies on different types of patients found long-term cognitive impairment in ICU survivors, possibly not disease specific. The proportions of patients with neuropsychological morbidities such as posttraumatic stress disorder, anxiety, and depression, described after our study, did not show any change over time.

CONCLUSIONS

Differences between studies on long-term survival and QOL do not allow conclusions to be drawn about change over time. No change was found in neuropsychological morbidities. However, a lack of change may not be viewed negatively, because critically ill patients who survive ICU today may be at higher risk for poor long-term outcome than in the past due to the higher severity of their illness and the more aggressive treatments received. Future studies may provide understanding of the relationships between psychiatric symptoms, cognitive impairment, functional disability, and QOL.

A rehabilitation intervention to promote physical recovery following intensive care: a detailed description of construct development, rationale and content together with proposed taxonomy to capture processes in a randomised controlled trial

BACKGROUND

Increasing numbers of patients are surviving critical illness, but survival may be associated with a constellation of physical and psychological sequelae that can cause ongoing disability and reduced health-related quality of life. Limited evidence currently exists to guide the optimum structure, timing, and content of rehabilitation programmes. There is a need to both develop and evaluate interventions to support and expedite recovery during the post-ICU discharge period. This paper describes the construct development for a complex rehabilitation intervention intended to promote physical recovery following critical illness. The intervention is currently being evaluated in a randomised trial (ISRCTN09412438; funder Chief Scientists Office, Scotland).

METHODS

The intervention was developed using the Medical Research Council (MRC) framework for developing complex healthcare interventions. We ensured representation from a wide variety of stakeholders including content experts from multiple specialties, methodologists, and patient representation. The intervention construct was initially based on literature review, local observational and audit work, qualitative studies with ICU survivors, and brainstorming activities. Iterative refinement was aided by the publication of a National Institute for Health and Care Excellence guideline (No. 83), publicly available patient stories (Healthtalkonline), a stakeholder event in collaboration with the James Lind Alliance, and local piloting. Modelling and further work involved a feasibility trial and development of a novel generic rehabilitation assistant (GRA) role. Several rounds of external peer review during successive funding applications also contributed to development.

RESULTS

The final construct for the complex intervention involved a dedicated GRA trained to pre-defined competencies across multiple rehabilitation domains (physiotherapy, dietetics, occupational therapy, and speech/language therapy), with specific training in post-critical illness issues. The intervention was from ICU discharge to 3 months post-discharge, including inpatient and post-hospital discharge elements. Clear strategies to provide information to patients/families were included. A detailed taxonomy was developed to define and describe the processes undertaken, and capture them during the trial. The detailed process measure description, together with a range of patient, health service, and economic outcomes were successfully mapped on to the modified CONSORT recommendations for reporting non-pharmacologic trial interventions.

CONCLUSIONS

The MRC complex intervention framework was an effective guide to developing a novel post-ICU rehabilitation intervention. Combining a clearly defined new healthcare role with a detailed taxonomy of process and activity enabled the intervention to be clearly described for the purpose of trial delivery and reporting. These data will be useful when interpreting the results of the randomised trial, will increase internal and external trial validity, and help others implement the intervention if the intervention proves clinically and cost effective.

Physical and cognitive performance of patients with acute lung injury 1 year after initial trophic versus full enteral feeding. EDEN trial follow-up

RATIONALE

We hypothesized that providing patients with acute lung injury two different protein/calorie nutritional strategies in the intensive care unit may affect longer-term physical and cognitive performance.

OBJECTIVES

To assess physical and cognitive performance 6 and 12 months after acute lung injury, and to evaluate the effect of trophic versus full enteral feeding, provided for the first 6 days of mechanical ventilation, on 6-minute-walk distance, cognitive impairment, and secondary outcomes.

METHODS

A prospective, longitudinal ancillary study of the ARDS Network EDEN trial evaluating 174 consecutive survivors from 5 of 12 centers. Blinded assessments of patients' arm anthropometrics, strength, pulmonary function, 6-minute-walk distance, and cognitive status (executive function, language, memory, verbal reasoning/concept formation, and attention) were performed.

MEASUREMENTS AND MAIN RESULTS

At 6 and 12 months, respectively, the mean (SD) percent predicted for 6-minute-walk distance was 64% (22%) and 66% (25%) (P = 0.011 for difference between assessments), and 36 and 25% of survivors had cognitive impairment (P = 0.001). Patients performed below predicted values for secondary physical tests with small improvement from 6 to 12 months. There was no significant effect of initial trophic versus full feeding for the first 6 days after randomization on survivors' percent predicted for 6-minute-walk distance, cognitive impairment status, and all secondary outcomes.

CONCLUSIONS

EDEN trial survivors performed below predicted values for physical and cognitive performance at 6 and 12 months, with some improvement over time. Initial trophic versus full enteral feeding for the first 6 days after randomization did not affect physical and cognitive performance.

Quality of life before admission to the intensive care unit

Objective

To examine the reliability of the SF-36 general health questionnaire when used to evaluate the health status of critically ill patients before admission to intensive care and to measure their health-related quality of life prior to admission and its relation to severity of illness and length of stay in the intensive care unit.

Methods

Prospective cohort study conducted in the intensive care unit of a public teaching hospital. Over three months, communicative and oriented patients were interviewed within the first 72 hours of intensive care unit admission; 91 individuals participated. The APACHE II score was used to assess severity of illness, and the SF-36 questionnaire was used to measure health-related quality of life.

Results

The reliability of SF-36 was verified in all dimensions using Cronbach's alpha coefficient. In six dimensions of eight domains the value exceeded 0.70. The average SF-36 scores of the health-related quality of life dimensions for the patients before admission to intensive care unit were 57.8 for physical functioning, 32.4 for role-physical, 53.0 for bodily pain, 63.2 for general health, 50.6 for vitality, 56.2 for social functioning, 54.6 for role-emotional and 60.3 for mental health. The correlations between severity of illness and length of stay and the health-related quality of life scores were very low, ranging from -0.152 to 0.175 and -0.158 to 0.152, respectively, which were not statistically significant.

Conclusion

In the sample studied, the SF-36 demonstrated good reliability when used to measure health-related quality of life in critically ill patients before admission to the intensive care unit. The worst score was role-physical and the best was general health. Health-related quality of life of patients before admission was not correlated with severity of illness or length of stay in the intensive care unit.

Health-related quality of life scores after intensive care are almost equal to those of the normal population: a multicenter observational study

INTRODUCTION

Health-related quality of life (HRQoL) in patients treated in intensive care has been reported to be lower compared with age- and sex-adjusted control groups. Our aim was to test whether stratifying for coexisting conditions would reduce observed differences in HRQoL between patients treated in the ICU and a control group from the normal population. We also wanted to characterize the ICU patients with the lowest HRQoL within these strata.

METHODS

We did a cross-sectional comparison of scores of the short-form health survey (SF-36) questionnaire in a multicenter study of patients treated in the ICU (n = 780) and those from a local public health survey (n = 6,093). Analyses were in both groups adjusted for age and sex, and data stratified for coexisting conditions. Within each stratum, patients with low scores (below -2 SD of the control group) were identified and characterized.

RESULTS

After adjustment, there were minor and insignificant differences in mean SF-36 scores between patients and controls. Eight (n = 18) and 22% (n = 51) of the patients had low scores (-2 SD of the control group) in the physical and mental dimensions of SF-36, respectively. Patients with low scores were usually male, single, on sick leave before admission to critical care, and survived a shorter time after being in ICU.

CONCLUSIONS

After adjusting for age, sex, and coexisting conditions, mean HRQoL scores were almost equal in patients and controls. Up to 22% (n = 51) of the patients had, however, a poor quality of life as compared with the controls (-2 SD). This group, which more often consisted of single men, individuals who were on sick leave before admission to the ICU, had an increased mortality after ICU. This group should be a target for future support.

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 and pruritus in patients with severe sepsis resuscitated with hydroxyethyl starch long-term follow-up of a randomised trial

INTRODUCTION

The effects of hydroxyethyl starch (HES) on patient-centered outcome measures have not been fully described in patients with severe sepsis. We assessed health-related quality of life (HRQoL) and the occurrence of pruritus in patients with severe sepsis randomized to resuscitation with HES 130/0.42 or Ringer's acetate.

METHODS

We did post hoc analyses of the Danish survivors (n=295) of the 6S trial using mailed questionnaires on self-perceived HRQoL (Short Form (SF) - 36) and pruritus.

RESULTS

Median 14 months (interquartile range 10 to 18) after randomization, 182 (61%) and 185 (62%) completed questionnaires were obtained for the assessment of HRQoL and pruritus, respectively. Responders were older than nonresponders, but characteristics at randomization of the responders in the HES vs. Ringer's groups were comparable. At follow-up, the patients in the HES group had lower mental component summary scores than those in the Ringer's group (median 45 (interquartile range 36 to 55) vs. 53 (39 to 60), P=0.01). The group differences were mainly in the scales of vitality and mental health. There was no difference in the physical component summary scores between groups, but patients in the HES group scored worse in bodily pain. Forty-nine percent of patients allocated to HES had experienced pruritus at any time after ICU discharge compared to 43% of those allocated to Ringer's (relative risk 1.13, 95% confidence interval 0.83 to 1.55, P=0.43).

CONCLUSIONS

At long-term follow-up patients with severe sepsis assigned to resuscitation with HES 130/0.42 had worse self-perceived HRQoL than those assigned to Ringer's acetate whereas there were no statistically significant differences in the occurrence of pruritus.

Long-term mortality and quality of life after septic shock: a follow-up observational study

PURPOSE

In septic shock, short-term outcomes are frequently reported, while long-term outcomes are not. The aim of this study was to evaluate mortality and health-related quality of life (HRQOL) in survivors 6 months after an episode of septic shock.

METHODS

This single-centre observational study was conducted in an intensive care unit in a university hospital. All patients with septic shock were included. Mortality was assessed 6 months after the onset of septic shock, and a comparison between patients who survived and those who died was performed. HRQOL was assessed using the MOS SF-36 questionnaire prior to hospital admission (baseline) and at 6 months in survivors. HRQOL at baseline and at 6 months were compared to the general French population, and HRQOL at baseline was compared to 6-month HRQOL.

RESULTS

Ninety-six patients were included. Six-month mortality was 45%. Survivors were significantly younger, had significantly lower lactate levels and SAPS II scores, required less renal support, received less frequent administration of corticosteroids, and had a longer length of hospital stay. At baseline (n = 39) and 6 months (n = 46), all of the components of the SF-36 questionnaire were significantly lower than those in the general population. Compared to baseline (n = 23), the Physical Component Score (CS) improved significantly at 6 months, the Mental CS did not differ.

CONCLUSIONS

Mortality 6 months after septic shock was high. HRQOL at baseline was impaired when compared to that of the general population. Although improvements were noted at 6 months, HRQOL remained lower than that in the general population.

The effect of acute kidney injury on long-term health-related quality of life: a prospective follow-up study

Introduction

Acute kidney injury (AKI) is a serious complication in critically ill patients admitted to the Intensive Care Unit (ICU). We hypothesized that ICU survivors with AKI would have a worse health-related quality of life (HRQOL) outcome than ICU survivors without AKI.

Methods

We performed a long-term prospective observational study. Patients admitted for > 48 hours in a medical-surgical ICU were included and divided in two groups: patients who fulfilled RIFLE criteria for AKI and patients without AKI. We used the Short-Form 36 to evaluate HRQOL before admission (by proxy within 48 hours after admission of the patient), at ICU discharge, hospital discharge, 3 and 6 months following ICU discharge (all by patients). Recovery in HRQOL from ICU-admission onwards was assessed using linear mixed modelling.

Results

Between September 2000 and January 2007 all admissions were screened for study participation. We included a total of 749 patients. At six months after ICU discharge 73 patients with AKI and 325 patients without AKI could be evaluated. In survivors with and without AKI, the pre-admission HRQOL (by proxy) and at six months after ICU discharge was significantly lower compared with an age matched general population. Most SF-36 dimensions changed significantly over time from ICU discharge. Change over time of HRQOL between the different AKI Rifle classes (Risk, Injury, Failure) showed no significant differences. At ICU discharge, scores were lowest in the group with AKI compared with the group without AKI for the physical functioning, role-physical and general health dimensions. However, there were almost no differences in HRQOL between both groups at six months.

Conclusions

The pre-admission HRQOL (by proxy) of AKI survivors was significantly lower in two dimensions compared with the age matched general population. Six months after ICU discharge survivors with and without AKI showed an almost similar HRQOL. However, compared with the general population with a similar age, HRQOL was poorer in both groups.

Health-related quality of life of long-term survivors of intensive care: changes after intensive care treatment. Experience of an Austrian intensive care unit

OBJECTIVE

The aim of the study was to determine if health-related quality of life of long-term survivors changes 24 months after intensive care treatment compared to the quality of life before admission.

METHODS

From 281 patients treated at the ICU in 2001, 132 survivors were contacted by phone on average 24 months after discharge. Fernandez questionnaire was used to assess preadmission quality of life prospectively and postdischarge quality of life, retrospectively. In addition, age, sex, admission diagnosis, ICU length of stay, presence of organ failure, and necessity of mechanical ventilation were determined.

RESULTS

In the 101 ICU survivors who responded to the questionnaire, the total score of quality of life did not change significantly over time (5.48 ± 5.3 before admission vs. 5.6 ± 5.8 at follow-up; p = 0.9). Similarly, the performance of normal daily activities did not alter (3.0 ± 3.5 vs. 3.39 ± 3.6; p = 0,3). In contrast, the ability to perform basic physiological activities worsened significantly (0.39 ± 0.76 vs. 0.76 ± 1.52; p = 0.037), whereas the emotional state improved significantly after intensive care treatment (2.08 ± 1.78 vs. 1.46 ± 1.56, p = 0.003). In a stepwise multiple regression analysis the total score of quality of life before admission was the only variable which influenced the quality of life 2 years after ICU-stay.

CONCLUSIONS

In the interviewed population the total score of health-related quality of life did not change after intensive care treatment. Surprisingly, emotional state improved significantly although physical performance decreased. Quality of life after ICU discharge was predominantly influenced by preadmission quality of life. However, these results are not reflective of all ICU survivors.

[Long-term outcome of elderly patients after intensive care treatment]

In general, elderly patients have poorer outcomes than younger patients after intensive care treatment. Diagnosis at admission and high age mainly influence short-term mortality within the first few months after intensive care, while comorbitities and functional status are more pivotal regarding long-term mortality. Furthermore, the main reasons for reduced physical fitness and neurocognitive consequences that often last for many months after intensive care treatment of older patients are described. Many outcome studies show that physical und mental sequelae after intensive care treatment are not only substantial but also unpredictable. Due to the constant improvement of intensive care treatment during recent decades, increasingly more patients survive their acute critical disease. Now it is time to focus on translational research to discover causal relationships between intensive care treatment and morbidity during follow-up to improve the quality of survival.

Physical effects of trauma and the psychological consequences of preexisting diseases account for a significant portion of the health-related quality of life patterns of former trauma patients

BACKGROUND

Health-related quality of life (HRQoL) is known to be significantly affected in former trauma patients. However, the underlying factors that lead to this outcome are largely unknown. In former intensive care unit (ICU) patients, it has been recognized that preexisting disease is the most important factor for the long-term HRQoL. The aim of this study was to investigate HRQoL up to2 years after trauma and to examine the contribution of the trauma-specific, ICU-related, sociodemographic factors together with the effects of preexisting disease, and further to make a comparison with a large general population.

METHODS

A prospective 2-year multicenter study in Sweden of 108 injured patients. By mailed questionnaires, HRQoL was assessed at 6 months,12 months, and 24 months after the stay in ICU by Short Form (SF)-36, and information of preexisting disease was collected from the national hospital database. ICU-related factors were obtained from the local ICU database. Comorbidity and HRQoL (SF-36) was also examined in the reference group, a random sample of 10,000 inhabitants in the uptake area of the hospitals.

RESULTS

For the trauma patients, there was a marked and early decrease in the physical dimensions of the SF-36 (role limitations due to physical problems and bodily pain). This decrease improved rapidly and was almost normalized after 24 months. In parallel, there were extensive decreases in the psychologic dimensions (vitality, social functioning, role limitations due to emotional problems,and mental health) of the SF-36 when comparisons were made with the general reference population.

CONCLUSIONS

The new and important finding in this study is that the trauma population seems to have a trauma-specific HRQoL outcome pattern.First, there is a large and significant decrease in the physical dimensions of the SF-36, which is due to musculoskeletal effects and pain secondary to the trauma. This normalizes within 2 years, whereas the overall decrease in HRQoL remains and most importantly it is seen mainly in the psychologic dimensions and it is due to preexisting diseases.

Lung function and quality of life in survivors of the acute respiratory distress syndrome (ARDS)

Recent studies have begun to describe the long-term outcomes of acute respiratory distress syndrome (ARDS) survivors. These patients experience a number of physical, mental and psychological morbidities that significantly impair their health-related quality of life (HRQL). The trajectory of pulmonary recovery in survivors of ARDS, as it relates to lung function, structure and health-related quality of life (HRQL), is predictable and often persists years after hospital discharge. True pulmonary parenchymal morbidity is uncommon and when present, persistent restrictive disease is likely related to diaphragmatic weakness with a mild reduction in diffusion capacity (DLCO). Future research should focus on identifying patients at risk for long-term functional limitations and the design of rehabilitation interventions tailored to individual patient needs.

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.

The Academic Medical Center Linear Disability Score for evaluation of physical reserve on admission to the ICU: can we query the relatives?

Introduction

Evaluating the pre-morbid functional status in critically ill patients is important and frequently done using the physical component score (PCS) of the Short Form 36, although this approach has its limitations. The Academic Medical Center Linear Disability Score (ALDS) is a recently developed generic item bank used to measure the disability status of patients with a broad range of diseases. We aimed to study whether proxy scoring with the ALDS could be used to assess the patients' functional status on admission for cardiac care unit (CCU) or ICU patients and how the ALDS relates to the PCS using the Short Form 12 (SF-12).

Methods

Patients and proxies completed the ALDS and SF-12 score in the first 72 hours following ICU scheduled surgery (n = 14), ICU emergency admission (n = 56) and CCU emergency admission (n = 70).

Results

In all patients (n = 140) a significant intra-class correlation was found for the ALDS (0.857), the PCS (0.798) and the mental component score (0.679) between patients and their proxy. In both scheduled and emergency admissions, a significant correlation was found between patients and their proxy for the ALDS, although the lowest correlation was found for the ICU scheduled admissions (0.755) compared with the ICU emergency admissions (0.889). In CCU patients, the highest significant correlation between patients and proxies was found for the ALDS (0.855), for the PCS (0.807) and for the mental component score (0.740).

Conclusions

Relatives in close contact with critically ill patients can adequately reflect the patient's level of disability on ICU and CCU admission when using the ALDS item bank, which performed at least as well as the PCS. The ALDS could therefore be a useful alternative for the PCS of the SF-12.

Does intensive care unit severity of illness influence recall of baseline physical function?

PURPOSE

The aim of this study is to evaluate if severity of illness in the intensive care unit influences patients' retrospective recall of their baseline physical function from before hospital admission.

MATERIALS AND METHODS

This is a prospective cohort study of 193 acute lung injury survivors who, before hospital discharge, retrospectively reported their prehospitalization physical function using the Short Form 36 quality of life survey.

RESULTS

Four measures were used to evaluate intensive care unit (ICU) severity of illness: (1) Acute Physiology and Chronic Health Evaluation II Acute Physiologic Score at ICU admission, (2) Lung Injury Score at acute lung injury diagnosis, (3) Sequential Organ Failure Assessment score at study enrollment, and (4) maximum daily Sequential Organ Failure Assessment score during the entire ICU stay. In multivariable linear regression analysis, no measure of severity of illness was associated with prehospitalization physical function. Education level significantly modified the relationship between ICU severity of illness and baseline physical function with lower educational attainment having a stronger association with baseline physical function.

CONCLUSION

Intensive care unit severity of illness was not associated with patients' retrospectively recalled baseline physical function. Patients with a lower level of education may be more influenced by ICU severity of illness, but the magnitude of this effect may not be clinically meaningful.

Health-related quality of life of survivors of penetrating trunk trauma in Johannesburg, South Africa

PURPOSE

To study how the health-related quality of life (HRQOL) of survivors of penetrating trunk trauma (PTT) changes from pre-morbid status to 6 months after hospital discharge and to determine differences in the HRQOL between subjects ventilated for short and prolonged periods of time. To determine how the HRQOL of PTT survivors compares with that of a healthy control group in order to identify limitations imposed by critical illness.

METHODS

Retrospective and observational prospective assessment of the quality of life (QoL) of PTT survivors with the Medical Outcomes Short Form-36 (SF-36) UK English version questionnaire. Cross-sectional assessment of the QoL of a healthy control group with the SF-36.

RESULTS

The physical component summary (PCS) score was significantly reduced for the short mechanical ventilation (MV) group (n = 13) at 1 and 3 months compared to pre-admission status (p = 0.00, respectively). The mental component summary (MCS) score was significantly reduced at 1, 3 and 6 months (p = 0.00, respectively). The PCS and MCS were significantly reduced for the long MV group (n = 29) at all three assessments compared to the pre-admission HRQOL (p = 0.00-0.01). The short MV group reported HRQOL comparable to that of the healthy group (n = 40) at 6 months after discharge. The long MV group had a significant reduction in the PCS at 1, 3 and 6 months compared to the healthy group (p = 0.00, respectively). The long MV group had significantly reduced PCS at 3 and 6 months compared to the short MV group (p = 0.01 and 0.00, respectively).

CONCLUSIONS

Subjects who had higher morbidity and prolonged MV suffered from reduced HRQOL related to physical health for up to 6 months after discharge.

Health-related quality of life before planned admission to intensive care: memory over three and six months

Background

The validity of Health-Related Quality of Life (HRQOL) recalled by ICU admitted patients have not been published. The aim of this study was to compare the baseline HRQOL measured before surgery and ICU admission with that recalled at 3 and 6 months in a population of patients with planned ICU admission after surgery.

Methods

This prospective study was performed in three Italian centres on patients who had undergone General, Orthopaedic or Urologic surgery. All adult patients with planned ICU admission between October 2007 and July 2008 were considered for enrolment. At hospital admission, the Mini Mental Status Examination and EuroQoL (EQ) questionnaire (referring to the last two weeks) were administered to the patients who consented. Three and six months after ICU admission, the researchers administered by phone the EQ questionnaire and Post-Traumatic Stress Syndrome 14 questions Inventory, asking the patients to rate their HRQOL before surgery and ICU admission. Past medical history demographic and clinical ICU-related variables were collected.

Statistical analysis

Chi-square test and non parametric statistics were used to compare groups of patients. The EQ-5D was transformed in the time trade-off (TTO) to obtain a continuous variable, subsequently analysed using the Intraclass Correlation Coefficient (ICC).

Results

Of the 104 patients assessed at baseline and discharged from the hospital, 93 had the EQ administered at 3 months, and 89 at 6 months. The ICC for TTO recalled at 3 months vs pre-ICU TTO was 0.851, and that for TTO recalled at 6 months vs pre-ICU TTO was 0.833. The ICC for the EQ-VAS recalled at 3 months vs pre-ICU EQ-VAS was 0.648, and that for the EQ-VAS recalled at 6 months vs pre-ICU EQ-VAS was 0.580. Forty-two (45%) patients assessed at 3 months gave the same score in all EQ-5D items as at baseline. They underwent mainly orthopaedic surgery (p 0.011), and perceived the severity of their illness as lower (p 0.009) than patients scoring differently at 3 months in comparison with baseline.

Conclusions

The patients with planned ICU admission have a good memory of their health status as measured by EQ-5D in the period preceding surgery and ICU admission, especially at three months.

Pre-existing disease: the most important factor for health related quality of life long-term after critical illness: a prospective, longitudinal, multicentre trial

INTRODUCTION

The aim of the present multicenter study was to assess long term (36 months) health related quality of life in patients after critical illness, compare ICU survivors health related quality of life to that of the general population and examine the impact of pre-existing disease and factors related to ICU care on health related quality of life.

METHODS

Prospective, longitudinal, multicentre trial in three combined medical and surgical intensive care units of one university and two general hospitals in Sweden. By mailed questionnaires, health related quality of life was assessed at 6, 12, 24 and 36 months after the stay in ICU by EQ-5D and SF-36, and information of pre-existing disease was collected at the 6 months measure. ICU related factors were obtained from the local ICU database. Comorbidity and health related quality of life (EQ-5D; SF-36) was examined in the reference group. Among the 5306 patients admitted, 1663 were considered eligible (>24 hrs in the intensive care unit, and age >or= 18 yrs, and alive 6 months after discharge). At the 6 month measure 980 (59%) patients answered the questionnaire. Of these 739 (75%) also answered at 12 month, 595 (61%) at 24 month, and 478 (47%) answered at the 36 month measure. As reference group, a random sample (n = 6093) of people from the uptake area of the hospitals were used in which concurrent disease was assessed and adjusted for.

RESULTS

Only small improvements were recorded in health related quality of life up to 36 months after ICU admission. The majority of the reduction in health related quality of life after care in the ICU was related to the health related quality of life effects of pre-existing diseases. No significant effect on the long-term health related quality of life by any of the ICU-related factors was discernible.

CONCLUSIONS

A large proportion of the reduction in the health related quality of life after being in the ICU is attributable to pre-existing disease. The importance of the effect of pre-existing disease is further supported by the small, long term increment in the health related quality of life after treatment in the ICU. The reliability of the conclusions is supported by the size of the study populations and the long follow-up period.

One-year mortality, quality of life and predicted life-time cost-utility in critically ill patients with acute respiratory failure

Introduction

High daily intensive care unit (ICU) costs are associated with the use of mechanical ventilation (MV) to treat acute respiratory failure (ARF), and assessment of quality of life (QOL) after critical illness and cost-effectiveness analyses are warranted.

Methods

Nationwide, prospective multicentre observational study in 25 Finnish ICUs. During an eight-week study period 958 consecutive adult ICU patients were treated with ventilatory support over 6 hours. Of those 958, 619 (64.6%) survived one year, of whom 288 (46.5%) answered the quality of life questionnaire (EQ-5D). We calculated EQ-5D index and predicted lifetime quality-adjusted life years (QALYs) gained using the age- and sex-matched life expectancy for survivors after one year. For expired patients the exact lifetime was used. We divided all hospital costs for all ARF patients by the number of hospital survivors, and by all predicted lifetime QALYs. We also adjusted for those who died before one year and for those with missing QOL to be able to estimate the total QALYs.

Results

One-year mortality was 35% (95% CI 32 to 38%). For the 288 respondents median [IQR] EQ-5D index after one year was lower than that of the age- and sex-matched general population 0.70 [0.45 to 0.89] vs. 0.84 [0.81 to 0.88]. For these 288, the mean (SD) predicted lifetime QALYs was 15.4 (13.3). After adjustment for missing QOL the mean predicted lifetime (SD) QALYs was 11.3 (13.0) for all the 958 ARF patients. The mean estimated costs were 20.739 € per hospital survivor, and mean predicted lifetime cost-utility for all ARF patients was 1391 € per QALY.

Conclusions

Despite lower health-related QOL compared to reference values, our result suggests that cost per hospital survivor and lifetime cost-utility remain reasonable regardless of age, disease severity, and type or duration of ventilation support in patients with ARF.

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.

[Variations in health-related quality of life in critical patients]

OBJECTIVE

To determine the changes in the health-related quality of life (hRQOL) six months after discharge from the ICU and the conditions associated to them.

DESIGN

A prospective cohort study.

SETTING

14 beds medical-surgical intensive care unit (ICU).

PATIENTS

A total of 247 patients admitted to our ICU for more than 24 hours with a follow-up of 6 months were study. Those admitted with acute coronary syndrome or for monitoring purposes were excluded.

INTERVENTION

A quality of life survey was conducted using the score developed by the PAEEC group (project of the epidemiological analysis of critical illness) to assess hRQOL before ICU admission and 6 months after discharge.

RESULTS

The hRQOL deteriorated, going from a median value of 3 to 6 (p < 0.001). The multivariate analysis showed less deterioration of hRQOL in patients with chronic health conditions registered on the APAChE-II score (regression coefficient [RC] = -1.4; 95% CI, -2.5 to -0.2; p < 0.02) and in those with a hRQOL > or = 10 points (RC = -4,4; 95% CI, -5.9 to -2.8; p < 0.001). There was more deterioration in polytraumatized patients (RC = 1.9; 95% CI, 0.6-3.3; p = 0.01) or with renal failure (RC = 3.9; 95% CI, 1.9-5.9; p < 0.001) or in those with a stay duration longer than 10 days (RC = 1.9; 95% CI, 0.6-3.2; p < 0.001).

CONCLUSIONS

Most patients experience deterioration of hRQOL. Patients with chronic diseases or with worst previous hRQOL who survive 6 months experience less deterioration of hRQOL than those who are polytraumatized or have renal failure or a longer ICU stay.

Six-month outcome in acute kidney injury requiring renal replacement therapy in the ICU: a multicentre prospective study

OBJECTIVE

To assess quality of life (QOL), mortality rate and renal function 6 months after onset of renal replacement therapy (RRT) for acute kidney injury (AKI) in the ICU.

PARTICIPANTS AND SETTING

This prospective observational study was conducted in seven ICUs in France over 9 months. Inclusion criteria were: age > or =18 years, RRT delivered for AKI and informed consent signed. AKI was defined from the RIFLE score. Recipients of kidney grafts or patients undergoing chronic RRT were not included.

MEASUREMENTS AND RESULTS

QOL was assessed using the Short Form Health Survey (SF-36) questionnaire together with the Index of Activities of Daily Living (ADL) (0: full assistance to 6: no assistance). SF-36 was compared to a reference age- and sex-matched French population. Patient status, place of residence, and persistence of RRT, ADL and SF-36 were assessed at 28 days, 3 months and 6 months from inclusion. In the study period, 205 patients were included and 1 withdrew. At 6 months, 77/204 were alive (mortality 62%). SF-36 and ADL significantly increased from day 28 to 6 months. In the survivors at 6 months, SF-36 items were significantly lower than in the reference population, with the physical items more severely affected than the mental items; 64% were fully autonomous (ADL score = 6); 69% were living in their homes, and 12% were still undergoing RRT; 94% would agree to undergo the same management again.

CONCLUSIONS

ICU survivors from RRT for AKI have an impaired QOL at 6 months, but sustained autonomy in their daily lives.

Quality of life and persisting symptoms in intensive care unit survivors: implications for care after discharge

BACKGROUND

We assessed the quality of life of ICU survivors using SF-36 at 4 months after ICU discharge and investigated any correlation of PCS and MCS with age, illness severity and hospital or ICU length of stay. We examined the relationship between these variables, persisting physical and psychological symptoms and the perceived benefit of individual patients of follow-up.

FINDINGS

For one year, adult patients admitted for multiple organ or advanced respiratory support for greater than 48 hours to a 16-bedded teaching hospital general intensive care unit were identified. Those surviving to discharge were sent a questionnaire at 4 months following ICU discharge assessing quality of life and persisting symptoms. Demographic, length of stay and illness severity data were recorded. Higher or lower scores were divided at the median value. A two-tailed Students t-test assuming equal variances was used for normally-distributed data and Mann-Whitney tests for non-parametric data.87 of 175 questionnaires were returned (50%), but only 65 had sufficient data giving a final response rate of 37%. Elderly patients had increased MCS as compared with younger patients. The PCS was inversely related to hospital LOS. There was a significant correlation between the presence of psychological and physical symptoms and desire for follow-up.

CONCLUSION

Younger age and prolonged hospital stay are associated with lower mental or physical quality of life and may be targets for rehabilitation. Patients with persisting symptoms at 4 months view follow-up as beneficial and a simple screening questionnaire may identify those likely to attend outpatient services.

Long-term physical outcome in patients with septic shock

BACKGROUND

Limited information is available on physical function after septic shock. The aim of the present study was to assess the physical outcome in survivors 1 year after septic shock.

METHODS

The outcome status of all 174 adult patients admitted to a mixed ICU with the diagnosis septic shock in a 1-year period was registered. Survivors were interviewed about physical function and socioeconomic status using a questionnaire including the Short Form-36 survey. The pre-ICU-admission Functional Comorbidity Index (FCI) was also registered.

RESULTS

Of the 80 survivors, two were still hospitalised; thus, 78 were invited to participate and 70 replied (inclusion-rate 88%). Patients were followed up at median 351 days after hospital discharge. At follow-up the patients had a markedly reduced physical component summary score (PCS) compared with age- and sex-adjusted general population controls (36 vs. 47, P<0.0001). This was also observed in patients with no comorbidity before ICU admission (34 vs. 47, P<0.001). There was a negative correlation (r=-0.27, P=0.03) between pre-ICU-admission FCI values and the PCS at follow-up. According to 81% of the patients, loss of muscle mass was the main cause of decreased physical function. Only 43% (10 vs. 23, P=0.01) of the previously employed had returned to work, and the number of patients in need of home-based personal assistance had doubled (10/20, P=0.04).

CONCLUSION

Physical function is substantially reduced in survivors of septic shock 1 year after discharge.

Individual quality of life in chronic kidney disease: influence of age and dialysis modality

BACKGROUND AND OBJECTIVES

Novel individualized quality-of-life (IQOL) measures permit patients with chronic kidney disease (CKD) to nominate unique areas of their lives that contribute to their well-being. This study assessed for differences in domains nominated by patients with CKD. We also examined the strength of association between (1) multidimensional health-related quality-of-life measures and IQOL and (2) psychosocial factors and IQOL.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

We performed a cross-sectional study of 151 patients who were undergoing peritoneal dialysis or hemodialysis or had stages 4 through 5 CKD. Patients completed the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQOL-DW), an instrument that assesses IQOL on the basis of patient-identified domains. Patients also completed health-related quality-of-life and psychosocial health measures.

RESULTS

Patients with CKD nominated many domains on the SEIQOL-DW, but family and health were the most common for all groups. Kidney disease was listed more frequently by peritoneal dialysis compared with hemodialysis patients or patients with CKD (31 versus 14 versus 5%, respectively). There were no significant differences in SEIQOL-DW scores between subgroups. SEIQOL-DW scores correlated with mental well-being and inversely correlated with chronic stress and depression.

CONCLUSIONS

Patients with advanced CKD demonstrate compromised quality-of-life scores comparable to dialysis patients. IQOL measures provide unique information that may help guide interventions that are better tailored to address patients' concerns about their well-being. These findings also suggest that renal clinics should have staff available to address psychosocial aspects of patient well-being.
