Patients with multimorbidity increasingly impact healthcare systems, both in primary care and in hospitals. This is particularly true in Internal Medicine. This population associates with higher mortality rates, polypharmacy, hospital readmissions, post-discharge syndrome, anxiety, depression, accelerated age-related functional decline, and development of geriatric syndromes, amongst others. Internists and Hospitalists, in one of their roles as Generalists, are increasingly asked to attend to these patients, both in their own Departments as well as in surgical areas. The management of polypathology and multimorbidity, however, is often complex, and requires specific clinical skills and corresponding experience. In addition, patients' needs, health-care environment, and routines have changed, so emerging and re-emerging specific competences and approaches are required to offer the best coordinated, continuous, and comprehensive integrated care to these populations, to achieve optimal health outcomes and satisfaction of patients, their relatives, and staff. This position paper proposes a set of emerging and re-emerging competences for internal medicine specialists, which are needed to optimally address multimorbidity now and in the future.

Introduction Cognitive impairment and depression in patients with heart failure (HF) are common comorbidities and are associated with increased morbidity, readmissions and mortality. Timely recognition of cognitive impairment and depression is important for providing optimal care. The aim of our study was to determine if these disorders were recognised by clinicians and, secondly, if they were associated with hospital admissions and mortality within 6 months’ follow-up. Methods Patients (aged ≥65 years) diagnosed with HF were included from the cardiology outpatient clinic of Gelre Hospitals. Cognitive status was evaluated with the Montreal Cognitive Assessment test (score ≤22). Depressive symptoms were assessed with the Geriatric Depression Scale (score >5). Patient characteristics were collected from electronic patient files. The clinician was blinded to the tests and asked to assess cognitive status and mood. Results We included 157 patients. Their median age was 79 years (65–92); 98 (62%) were male. The majority had New York Heart Association functional class II. Cognitive impairment was present in 56 (36%) patients. Depressive symptoms were present in 21 (13%) patients. In 27 of 56 patients (48%) cognitive impairment was not recognised by clinicians. Depressive symptoms were not recognised in 11 of 21 patients (52%). During 6 months’ follow-up 24 (15%) patients were readmitted for HF-related reasons and 18 (11%) patients died. There was no difference in readmission and mortality rate between patients with or without cognitive impairment and patients with or without depressive symptoms. Conclusion Cognitive impairment and depressive symptoms were infrequently recognised during outpatient clinic visits.

Delirium is een veelvoorkomende complicatie in het ziekenhuis bij oudere patienten met een heupfractuur. Het risico op een delirium kan verlaagd worden door tijdige inzet van preventieve maatregelen. In Gelre ziekenhuizen hebben wij de voorspellende waarde van het in Nederland veelal gebruikte VMS (veiligheidsmanagementsysteem)-screeningsinstrument onderzocht. De voorspellende waarde hiervan bleek matig.

Background Cancer societies and research cooperative groups worldwide have urged for the development of cancer trials that will address those outcome measures that are most relevant to older patients. We set out to determine the characteristics and study objectives of current clinical trials in hematological patients. Method The United States National Institutes of Health clinical trial registry was searched on 1 July 2013, for currently recruiting phase I, II or III clinical trials in hematological malignancies. Trial characteristics and study objectives were extracted from the registry website. Results In the 1207 clinical trials included in this overview, patient-centered outcome measures such as quality of life, health care utilization and functional capacity were only incorporated in a small number of trials (8%, 4% and 0.7% of trials, respectively). Even in trials developed exclusively for older patients, the primary focus lies on standard end points such as toxicity, efficacy and survival, while patient-centered outcome measures are included in less than one-fifth of studies. Conclusion Currently on-going clinical trials in hematological malignancies are unlikely to significantly improve our knowledge of the optimal treatment of older patients as those outcome measures that are of primary importance to this patient population are still included in only a minority of studies. As a scientific community, we cannot continue to simply acknowledge this issue, but must all participate in taking the necessary steps to enable the delivery of evidence-based, tailor-made and patient-focused cancer care to our rapidly growing elderly patient population.

Background:Delirium is a common neuropsychiatric syndrome with considerable heterogeneity in clinical profile. Identification of clinical subtypes can allow for more targeted clinical and research efforts. We sought to develop a brief method for clinical subtyping in clinical and research settings.Methods:A multi-site database, including motor symptom assessments conducted in 487 patients from palliative care, adult and old age consultation-liaison psychiatry services was used to document motor activity disturbances as per the Delirium Motor Checklist (DMC). Latent class analysis (LCA) was used to identify the class structure underpinning DMC data and also items for a brief subtyping scale. The concordance of the abbreviated scale was then compared with the original Delirium Motor Subtype Scale (DMSS) in 375 patients having delirium as per the American Psychiatric Association's Diagnostic and Statistical Manual (4th edition) criteria.Results:Latent class analysis identified four classes that corresponded closely with the four recognized motor subtypes of delirium. Further, LCA of items (n = 15) that loaded >60% to the model identified four features that reliably identified the classes/subtypes, and these were combined as a brief motor subtyping scale (DMSS-4). There was good concordance for subtype attribution between the original DMSS and the DMSS-4 (κ = 0.63).Conclusions:The DMSS-4 allows for rapid assessment of clinical subtypes in delirium and has high concordance with the longer and well-validated DMSS. More consistent clinical subtyping in delirium can facilitate better delirium management and more focused research effort.

Background: In clinical practice lateral images of the chest are performed for various reasons. As these lateral chest X rays show the vertebrae of the thoracic and thoraco-lumbar region, we wondered if these X-rays can be used for evaluation of vertebral fractures instead of separate thoracic spine X-rays. Methods: To evaluate the agreement and intraobserver reliability of the semi-quantitative method for vertebral fractures on the lateral chest X-ray (X-chest) in comparison to the lateral thoracic spine X-ray (X-Tspine), two observers scored vertebral fractures on X-Tspine and twice on X-chest, separately, blinded and in different time periods. Agreement and Cohens' kappa were calculated for a diagnosis of any fracture on patient level and on vertebral body level. The study was done in patients visiting an outpatient geriatric day clinic, with a high prevalence of vertebral fractures. Results: 109 patients were included. The intraobserver agreement for X-chest versus X-Tspine was 95-98% for the two levels of fracturing, with a Cohen's kappa of 0.88-0.91. The intraobserver agreement and reliability of the re-test on the X-chest showed an agreement between 91 and 98% with a Cohen's kappa of 0.81-0.93. More vertebrae were visible on the X-chest, mean 10.2, SD 0.66 versus mean 9.8, SD 0.73 on the X-Tspine (p

Background In a Dutch multicentre study, elderly (65 + year) metastatic breast cancer patients, eligible for first-line chemotherapy, were randomised between two types of single-agent chemotherapy. As accrual was slow, with 78 randomised patients between April 2007 and September 2011, we explored potential barriers in the accrual process and their consequences for characteristics of included patients. Methods We sent surveys on the reasons for non-inclusion to all coordinating investigators. We also examined inclusion in a concurrent, non-elderly breast cancer study of the trialists' group and analysed baseline geriatric characteristics of included patients. Results Investigators from fifteen participating centres returned the survey. Most commonly reported barriers to inclusion were: patient's refusal of chemotherapy ( n = 8) or of randomisation ( n = 9), impaired cognition ( n = 3) and insufficient cardiac function ( n = 2). Oncologists' preference for combination regimens over single-agent chemotherapy was reported twice. Twenty-eight potentially eligible patients, aged 65–71 years, were included in a concurrent, study investigating combination chemotherapy in fit non-elderly patients with metastatic breast cancer. However, baseline characteristics of the included patients showed that the OMEGA study succeeded in including frail and older patients, with a performance status of 2 in 22% of patients and 54% of patients aged 75 years or older. Conclusion Accrual in this study was mainly hampered by patient's refusal or preference for a particular type of treatment, and an overall condition considered as too fit or too frail for inclusion. Future trials in elderly metastatic breast cancer patients should focus on non-restrictive inclusion criteria as well as on education of physicians and elderly patients on the advantages of trial participation.

Background Reduced muscle density is associated with an increased risk of postoperative complications. We examined the prognostic value of muscle density as a predictor of postoperative complications in elderly patients undergoing surgery for colorectal cancer. Methods Patients (≥70 years) who underwent surgery for colorectal cancer between 2006 and 2013 were selected from a prospective single centre database. The Hounsfield Unit Average (HUA or HU/mm 2 ) of the psoas muscles at the level of the third lumbar vertebra was calculated on the scan. High and low muscle density groups were identified based on the lowest gender specific HUAC quartile. Major postoperative complications (Clavien-Dindo (CD) ≥3) within 30 days after surgery were retrospectively documented. Logistic regression analysis was used to identify risk factors for postoperative complications. Results A total of 373 patients (median age = 78 years) were included in this study. The mean muscle density score was 24.5 ± 4.3 HU/mm 2 for males and 26.3 ± 5.0 HU/mm 2 for females. The cut-off point for the lowest gender specific quartile was ≤22.0 HU/mm 2 for males and ≤23.5 HU/mm 2 for females. After multivariable regression, there was a statistically significant association between muscle density and CD ≥ 3 (OR = 1.84 (95% CI 1.11–3.06), p = 0.019). Anastomotic leakage in patients with a primary anastomosis (n = 287) occurred more often in patients with low muscle density (11.7% vs 23.3%, p = 0.016). The associations remained significant after correction for confounders. Conclusion Low muscle density is associated with major postoperative complications in older patients who undergo surgery for colorectal cancer.

In a prospective cohort study of 395 geriatric outpatients, mortality after 3 years was associated with prevalent vertebral fractures at baseline. The mortality risk was independently associated with the presence of three or more vertebral fractures at baseline. In the surviving patients, the risk of incident fractures was noteworthy, occurring in 26 % of these patients. The purpose of this study is to determine mortality rate and the incidence of vertebral fractures in a geriatric outpatient group, during a 3-year follow-up period, in a teaching hospital in Amsterdam, The Netherlands. This study includes a prospective cohort study of 395 geriatric patients who had their baseline visit at a diagnostic day hospital in 2007 and 2008. They were invited for follow-up 3 years later. Lateral X-rays of the lumbar spine and chest were performed at baseline and after 3 years; vertebral fractures were scored in all patients according to the semi-quantitative method of Genant. After 3 years, mortality was 46 % and associated with prevalent vertebral fractures at baseline (odds ratio (OR), 1.83; 95 % CI, 1.23-2.74). The presence of three or more vertebral fractures at baseline was an independent risk factor for mortality (OR, 3.32; 95 % CI, 1.56-7.07). Other independently associated risk factors were greater age, higher co-morbidity score, and having more prescriptions. Higher cognitive capacity protected against mortality after 3 years. In 72 patients, radiography was repeated. Nineteen patients (26 %) had an incident radiographic vertebral fracture: 16 in those with a prevalent fracture, and 3 in those without a prevalent vertebral fracture at baseline. In geriatric outpatients, mortality after 3 years was associated with prevalent vertebral fractures at baseline, and the mortality risk was independently associated with 3 or more vertebral fractures at baseline. In survivors, the risk of incident fractures was noteworthy, since these occurred in 26 % of the patients, particularly in those with a prevalent vertebral fracture.

Objective: Circadian rhythm disturbances, like sundowning, are seen in dementia. Because the circadian rhythm is regulated by the biological clock, melatonin might be effective in the treatment of these disturbances. We systematically studied the effect of melatonin treatment in patients with dementia. In addition, we elaborate on the possible effects one might expect of melatonin treatment in patients with delirium, since dementia and delirium are strongly related. Moreover, some evidence exists that sundowning in patients with dementia and the alterations in the sleep/wake cycle, seen in patients with delirium both originate from circadian rhythm disturbances. Design: A systematic search of the literature, published between 1985 and April 2009, was performed using PubMed and other databases. All papers on melatonin treatment in dementia were retrieved. Effects of melatonin on circadian rhythm disturbances were scored by means of scoring sundowning/agitated behaviour, sleep quality and daytime functioning. Results: Nine papers, including four randomised controlled trials (RCTs) (n = 243), and five case series (n = 87) were reviewed. Two of the RCTs found a significant improvement on sundowning/agitated behaviour. All five case series found an improvement. The results on sleep quality and daytime functioning were inconclusive. Conclusion: Sundowning/agitated behaviour improves with melatonin treatment in patients with dementia. There are several arguments that sundowning in patients with dementia and the alterations in the sleep/wake cycle in patients with delirium have a common background, namely a disturbance of the circadian rhythm. This suggests that melatonin treatment could also have the same positive effects in patients with delirium. Copyright (C) 2010 John Wiley & Sons, Ltd

AIM: Prehabilitation, defined as enhancement of the preoperative condition of a patient, is a possible strategy for improving postoperative outcome. Lack of muscle strength and poor physical condition, increasingly prevalent in older patients, are risk factors for postoperative complications. Eighty-five per cent of patients with colorectal cancer are aged over 60 years. Since surgery is the cornerstone of their treatment, this review systemically examined the literature on the effect of physical prehabilitation in older patients undergoing colorectal surgery.METHOD: Trials and case-control studies investigating the effect of physical prehabilitation in patients over 60 years undergoing colorectal surgery were retrieved from MEDLINE, EMBASE, CINAHL and the Cochrane library. Patient characteristics, the type of intervention and outcome measurements were recorded. The risk of bias and heterogeneity was assessed.RESULTS: Five studies including 353 patients were identified. They were small, containing an average of 77 patients and were of moderate methodological quality. Compliance rates of the prehabilitation programme varied from 16 to 97%. None of the studies could identify a significant reduction of postoperative complications or length of hospital stay. Four studies showed physical improvement (walking distance, respiratory endurance) in the prehabilitation group. Clinical heterogeneity precluded a meta-analysis.CONCLUSION: Prehabilitation is a possible means of enhancing the physical condition of patients preoperatively. The quality of studies in older patients undergoing colorectal surgery is poor, despite the increase in elderly people with colorectal cancer. Defining specific patient groups at risk and standardizing the outcome are essential for improving the results of treatment.

Currently over 55% of end-stage renal disease (ESRD) patients are aged ≥60 years and patients >75 years represent the fastest growing segment of the dialysis population. We aimed to assess whether the Groningen frailty indicator (GFI) can be used to distinguish fit older ESRD patients, likely able to tolerate and benefit from dialysis, from frail older patients who need further evaluation with a geriatrician's comprehensive assessment. All patients aged ≥65 years visiting the pre-dialysis unit at the Gelre hospital between 2007 and 2013 were included and underwent the GFI (n = 65). Patients with GFI ≥ 4 (frail) were referred for geriatric consultation (n = 13). Results of the GFI and nephrologists' evaluation were compared with geriatrician's assessment. Survival rates and outcomes after one year of follow up were recorded. Twenty patients (32%) were identified as frail. Of the problems identified by the geriatrician in 13 patients, 55% were not reported in the nephrologists' notes. The first year after inclusion, 30% of patients with a GFI ≥ 4 died, compared to 9% of fit patients (p = 0.04). Moreover, 90% of frail patients had been hospitalized one or more times, compared to 53% in the fit group (p = 0.005). Although the GFI can be a useful instrument to identify ESRD patients at risk, both the GFI and the nephrologists' assessment failed to identify specific geriatric impairments. Further research is needed to develop a specific frailty indicator for ESRD patients and to determine the value and effect of a comprehensive geriatric assessment in ESRD patients

Objectives: Delirium is common in older patients admitted to hospital. Information obtained from patient's relatives or caregivers may contribute to improved detection. Our aim was to develop a caregiver based questionnaire, the Informant Assessment of Geriatric Delirium (I-AGeD), to assist in better recognition of delirium in elderly patients. Methods: A cross-sectional observational study using a scale construction patient cohort and two validation cohorts was conducted at geriatric departments of two teaching hospitals in the Netherlands. Delirium status, based on DSM-IV criteria, was assessed directly on admission by a geriatric resident and research coordinator and evaluated within the first 48 hours of admission. Questionnaire item sampling was based on discussions with an expertpanel. Caregivers filled out a 37-item questionnaire of which ten items were selected reflecting delirium symptoms, based on their discriminatory abilities, internal consistency and interitem correlations. Results: A total of 88 patients with complete study protocols in the construction cohort were included. Average age was 86.4 (SD 8.5), and 31/88 patients had delirium on admission. Internal consistency of the 10-item I-AGeD was high (Cronbach's alpha = 0.85). At a cut-off score greater than 4 sensitivity was 77.4% and specificity 63.2%. In patients without dementia, sensitivity was 100% and specificity 65.2%. Validation occurred by means of two validation cohorts, one consisted of 59 patients and the other of 33 patients. Sensitivity and specificity in these samples ranged from 70.0-88.9% and 66.7%-100%. Conclusion: The newly constructed caregiver based I-AGeD questionnaire is a valid screening instrument for delirium on admission to hospital in geriatric patients.

Sleep deprivation is common in intensive care unit (ICU) patients. The criterion standard for sleep monitoring, polysomnography, is impractical in ICU. Actigraphy (a wrist watch indicating amount of sleep) proved to be a good alternative in non-ICU patients, but not in prolonged mechanically ventilated patients, probably due to ICU-acquired weakness. Short-stay ICU patients do not suffer from ICU-acquired weakness. However, the accuracy of actigraphy is unknown in these patients. Therefore, we compared actigraphy to polysomnography in short-stay ICU patients. Sleep measurements were conducted in 7 postcardiothoracic surgery patients. The sensitivity (percentage of actigraphy data that agreed with sleep determined using polysomnography) and specificity (percentage of actigraphy data that agreed with awake determined using polysomnography) were calculated. The result showed that actigraphy underestimated the amount of wake time and overestimated the amount of sleep. The median specificity for actigraphy was always less than 19% and sensitivity more than 94%. Therefore, actigraphy is not reliable for sleep monitoring in short-stay ICU patients.

Introduction: Information to treat geriatric patients evidence-based is hard to find. Recently, a sensitive and a specific search filter to improve searching for literature relevant to geriatric medicine were developed in a research setting. The aim of this study is to determine whether these filters are able to find the articles considered relevant for daily clinical practice by young geriatricians. Materials and methods: For this study, we included references identified for lectures of the session of the 9th European Academy for Medicine of Ageing (EAMA) course 2011 about "Ageing and functionality" and lectures of the session entitled "Evidence-Based Medicine" (EBM). Relevant references were combined with the specific and sensitive search strategy in MEDLINE. Results: Of the 50 relevant articles for the course "Functionality", the sensitive filter identified 46 (92%); the specific filter 39 (78%). Of the 92 relevant references on "EBM", the sensitive filter retrieved 80 (87%), the specific filter 59 (64%). Articles not identified by the sensitive filter, were mostly missed because the filter specifically search for relevant terms mentioned in title or abstract. Conclusion: Geriatricians can be confident that the majority of relevant articles will be retrieved by the sensitive search filter. Searching for literature will be simplified and made more efficient by using a search filter. By demonstrating the pros of the filter we hope to stimulate implementation in daily clinical practice, so our elderly population is as much treated by the most up to date available evidence as possible.

Background/Aims: A disturbed sleep-wake rhythm cycle can be seen in delirium and as melatonin regulates this cycle via melatonin receptors, genetic variations in these receptors may contribute to susceptibility to delirium. The purpose of this study was to investigate whether genetic variants in the melatonin receptor 1B (MTNR1B) gene are associated with delirium. Methods: Elderly medical and hip surgery patients were included in the study. Five single-nucleotide polymorphisms (SNPs) were determined in the MTNR1B gene, i.e. rs18030962, rs3781638, rs10830963, rs156244 and rs4753426. Results: In total, 53% of 171 hip fracture patients and 33% of 699 medical patients were diagnosed with delirium. None of the polymorphisms were found to be associated with the occurrence of delirium. Conclusion: Future research could focus on sequencing this gene to look for other functional SNPs in relation to delirium. Copyright (C) 2012 S. Karger AG, Basel

Delirium is the most common mental disorder at older age in hospitals after acute admission. The pathogenesis of delirium is largely unknown. Hyperactivity of the hypothalamic-pituitary-adrenal axis, leading to increased cortisol levels, has been suggested to play a role in the development of delirium. The effects of cortisol, the most important glucocorticoid (GC) in humans, are mainly mediated by the GC receptor (GR). Several polymorphisms in the GR gene that alter the GC sensitivity are known. The aim of this study was to study the role of these GR polymorphisms in delirium in elderly patients. Patients aged 65 years and older admitted to the medical department or scheduled for hip surgery were included. Delirium was diagnosed using the Confusion Assessment Method. Five single nucleotide polymorphisms in the GC receptor gene were genotyped and haplotypes were constructed. Delirium was associated with impaired cognitive (P

Both the patient's and the caregiver's perspectives are discussed. The guideline includes chapters on epidemiology, etiology and risk factors, and the non-pharmacological and pharmacological prevention and treatmentof delirium. Inaddition, onechapter is dedicated to the ‘organization of care’. This latter chapter was more heavily based on expert opinion than the other chapters.

Introduction Delirium is a common neuropsychiatric syndrome with considerable heterogeneity that includes a variety of clinical (motor) subtypes. Because delirium is typically highly fluctuating, understanding the longitudinal stability of subtypes is crucial to evaluating their relevance to treatment and outcome. Aims to examine the changes (variability) in motor subtype profile in patients with delirium over serial assessment using the Delirium Motor Subtype Scale, and to investigate predictors of variability. Methods We studied motor subtype profile of patients with delirium assessed daily over a week in elderly patients undergoing hip fracture surgery. A Generalized Estimating Equations Model examined possible predictors of change in motor subtype status, including baseline variables and delirium course. Results We included 118 patients developing DSM-IV delirium after hip-surgery [mean age 87.0±6.5 years; range 65–102; 66% females]. At first assessment, hyperactive subtype was most common (49%), followed by hypoactive (31%) and mixed subtype (14%), with 6% of delirious patients not fulfilling criteria of any DMSS-defined motor subtype. Almost two-thirds (n=69) of these patients underwent at least one more assessment, and for these 45 (57%) remained stable in motor subtype over time, while the rest 34 (43%) underwent change. A range of baseline characteristics were not significant predictors of variability in subtype profile. Conclusions Motor subtype profile is typically stable for orthopaedic patients with delirium. Thus evidence from cross-sectional studies of motor subtypes can be applied to many patients with delirium. Further longitudinal studies can clarify the stability of motor subtypes across different clinical populations.

Wij hebben onderzocht op welke manier meer resultaten uit wetenschappelijk onderzoek (wetenschappelijk bewijs of ‘evidence’) specifiek voor ouderen verkregen kan worden en hoe dat het beste door artsen die met ouderen werken in de klinische praktijk kan worden toegepast. Ouderen zijn namelijk vaak uitgesloten van klinische studies omdat ze bijvoorbeeld teveel comorbiditeit hebben, maar ook soms zonder duidelijke reden. Ook hebben zelf nieuwe evidence gecreeerd door het uitvoeren van een gerandomiseerde gecontroleerde studie (RCT) uitgevoerd naar het effect van paracetamol op slaapproblemen bij ouderen. Er zijn meerdere manieren om de toepassing van evidence-based medicine in de geriatrie te verbeteren. Door met onze zoekfilters medische databases te doorzoeken verloopt dit efficienter. Daarnaast maakt het samenvatten van bewijs in systematische reviews en scoping reviews duidelijk op welke vlakken meer bewijs nodig is. Individuele patienten data (IPD) zouden voor iedereen beschikbaar moeten komen, waardoor het makkelijker wordt om de gegevens van oudere patienten samen te voegen in een IPD review. Trials die beogen ouderen te includeren moeten zodanig opgezet worden dat de kans dat de inclusie wordt gehaald hoog is. Voordat een trial wordt uitgevoerd zou een pilot gedaan moeten worden om de haalbaarheid van de studie vast te stellen. Door deze maatregelen wordt de zorg en behandeling van ouderen meer gebaseerd op wetenschappelijk bewijs, hetgeen hopelijk zal bijdragen aan betere zorg voor deze groeiende groep.

In the Netherlands, it is estimated that yearly between 40,000 and 160,000 patients develop delirium in the hospital. In a substantial part of the hospitals, a hospital-wide policy regarding prevention, treatment and care of patients with delirium is missing. However, in 2010, The Dutch Health Care Inspectorate launched new regulatory that requires that by 2012, every hospital has to have a delirium screening program and a hospital-wide protocol for delirium in patients of 70 years and older. Secondly, despite the fact that at this moment only around two-third of the hospitals are equipped with a geriatric team, there has to be 24 h availability of specialized personnel for the management of delirium. In this article, the management for an average patient with delirium is described based on the Dutch national guideline for delirium of 2005. We expect that the insufficiencies in delirium care found by the Inspectorate will not be solved in 2012, but hopefully this new policy will help doctors and hospitals with tools and new incentives to develop better standard care for patients with delirium in the future in the Netherlands.

Summary In a prospective cohort study of 395 geriatric outpatients, mortality after 3 years was associated with prevalent vertebral fractures at baseline. The mortality risk was independently associated with the presence of three or more vertebral fractures at baseline. In the surviving patients, the risk of incident fractures was noteworthy, occurring in 26 % of these patients.

Sleep deprivation is common in ICU patients, but difficult to investigate [1]. The gold standard for sleep monitoring, polysomnography (PSG), is impractical for use in ICU patients [2]. Actigraphy proved to be a good alternative in non-ICU patients [3]. However, in prolonged mechanically ventilated patients, actigraphy was inaccurate, probably due to ICU-acquired weakness and resulting inactivity [2]. Short-stay ICU patients do not suffer from ICU-acquired weakness, and the accuracy of actigraphy in these patients has not yet been studied [4]. The aim of this study was to investigate actigraphy for sleep assessment in short-stay ICU patients.
