Observed daytime sleepiness in in-hospital geriatric patients and risk of falls.

BACKGROUND: Daytime sleepiness and falls are frequent in geriatric in-hospital patients; however, the relationship between both events is not clear. To test the hypothesis that observed daytime sleepiness is associated with falls in geriatric in-hospital patients data collected from medical records of patients who were admitted to an acute geriatric department were retrospectively analyzed. METHODS: The data from the medical records of patients who were admitted to the geriatric department of the Alfried-Krupp-Hospital in Essen, Germany in the period from January 2018 to March 2020 were retrospectively analyzed. Personal data, data concerning the geriatric assessment, observed daytime sleepiness, and falls were recorded. RESULTS: From a total of 1485 patients who were consecutively admitted to hospital, the data of 1317 (87%) patients could be included for further analysis. During the hospital stay 146 (11%) patients fell at least once, 35 (3%) patients had more than 1 fall and 64 falls (44%) occurred while patients were standing (bipedal fall). Daytime sleepiness was observed in 73% of the patients with bipedal falls and in 65% patients with nonbipedal falls (p < 0.01). Falls correlated significantly with the history of a recent fall, the length of hospital stay, the Barthel index (BI) on admission, the mini mental state examination (MMSE), dementia and observed daytime sleepiness. No correlation was found between falls and age, multimorbidity, and the number of drugs used. Drugs related to falls were medications to treat Parkinson's disease, antidepressants and neuroleptics. In a multiple logistic regression analysis in-hospital falls were significantly and independently associated with a history of falls, length of in-hospital stay, dementia, and observed daytime sleepiness. CONCLUSION: Observed daytime sleepiness is associated with in-hospital falls in geriatric patients. Prospective interventional studies are needed to confirm this relationship, and to quantify the impact of sleepiness on the risk of falling. Additionally, the impact of treatment for observed daytime sleepiness on the risk of falling should be assessed. The assessment of sleepiness should become a routine task in geriatrics.

[Frailty phenotype and risk factor for disturbed sleep]. / Frailty-Phänotyp und Risikofaktor gestörter Schlaf.

Regardless of the nature of its operationalization, frailty has significant negative consequences for the person concerned and the community. Even if a generally accepted definition of frailty is still missing, there is no doubt about the existence of this phenomenon. Pathophysiologically, a dysfunctional interaction between multiple complex systems is discussed. Therapeutic interventions show that frailty is a dynamic state that can be improved. The pathophysiological characteristics of frailty and sleep disturbances show numerous similarities. In addition, the risk of frailty is increased in individuals with sleep disturbances. As the majority of sleep disorders can usually be well treated, screening for sleep disorders should be integrated into a comprehensive concept of management of frailty.

Developing a novel tool to assess the ability to self-administer medication in non-demented in-hospital patients: ABLYMED study protocol.

BACKGROUND: Older people often suffer from multimorbidity resulting in polypharmacy. The correct administration of medication is a crucial factor influencing treatment efficacy. However, tools for evaluating the ability to self-administer different dosage forms of medications are lacking. The objectives of the ABLYMED study are to 1) assess the ability to self-administer different dosage forms of medication in older non-demented in-hospital patients who report autonomous management of medication, 2) identify factors influencing the ability to self-administer medication, and 3) develop a standardized tool to validly assess the ability to self-administer different dosage forms of medications based on the final study results. METHODS: One hundred in-patients from the department of orthopedics and trauma surgery of the University Hospital Düsseldorf  ≥ 70 years of age and regularly taking ≥ 5 different drugs autonomously will be prospectively recruited into the observational cross-sectional single-center ABLYMED study. Patients undergo an interview addressing demographic and clinical information, medication history (which medications are taken since when, in which dose and dosage form, and subjective proficiency of taking these medications), medication adherence, and factors possibly influencing adherence including personality traits and perceived quality of the medication regimen. Quality of the medication regimen is also rated by clinicians according to validated lists. Further, patients receive a comprehensive geriatric assessment including measures of cognition, mobility, and functional status. The ability to self-administer medication is assessed by having patients perform different tasks related to medication self-administration, which are video recorded and rated by different experts. The patients' self-reported ability will be correlated with the observed performance in the self-administration tasks. Further, factors correlating with the reported and observed ability to self-administer medication will be evaluated using correlation and regression models. Based on the final study results, a novel tool to assess the ability of older patients to self-administer medication will be developed. DISCUSSION: In addition to guideline-based pharmacotherapy, correct intake of prescribed medication is crucial for optimal therapy of multimorbidity in older people. Tools to validly assess the ability of older patients to self-administer different dosage forms of medications are lacking, but should be included in comprehensive geriatric assessments to secure functional health. TRIAL REGISTRATION: Development of an assessment instrument to evaluate the ability to manage various dosage forms, DRKS-ID: DRKS00025788 , (date of registration: 07/09/2021).

[Lung function test in advanced age]. / Lungenfunktionsprüfung im höheren Lebensalter.

Advanced age is not an obstacle to carring out a lung function test. In most cases a lung function test is necessary due to the fact that about 20% of older persons are affected by an obstructive respiratory disorder. Standard values for the lung function test are available up to advanced ages. The experience of the examiner and a calm environment for the lung function test have an impact on the quality of the measurement results. Severe cognitive impairments and severe immobility make the performance of a lung function test impossible. Simple geriatric assessments can help to reliably identify these patients. Alternative lung function test procedures have to be validated in order to adequately diagnose this vulnerable subgroup of patients at risk.

Developing an Alternative Version of the Epworth Sleepiness Scale to Assess Daytime Sleepiness in Adults with Physical or Mental Disabilities.

INTRODUCTION: Excessive daytime sleepiness (EDS) is a frequent symptom with many possible causes, and many of these can be treated. EDS and its underlying causes have been associated with various negative health consequences. Recognition of EDS is thus an important public health concern. The concept of EDS is, however, not yet well defined, and different measures are used to diagnose EDS. The Epworth Sleepiness Scale (ESS) is the most widely used tool to assess daytime sleepiness in a broad range of populations. Its applicability in patients exhibiting physical or mental disabilities, like older multimorbid patients, is limited, since the ESS was not developed and validated in this patient group. METHODS: Within an expert study with 35 sleep medicine experts and a pilot study with 52 geriatric in-patients, who frequently exhibit physical or mental disabilities, and patients' close relatives, we adapted the original ESS to develop an alternative version to assess daytime sleepiness in adults with physical or mental disabilities (ESS-ALT). RESULTS: In this adapted version, items 3 (sitting inactively in a public place) and 8 (sleepy in traffic) were replaced by 2 new items (sitting in a waiting room, sitting and eating a meal) and an interview format was used. This ESS-ALT achieved fewer missing responses (23 vs. 73%) and a higher level of internal consistency (Cronbach's α = 0.64 vs. 0.23) than the original ESS while keeping its somnificity structure. CONCLUSION: The ESS-ALT achieves better psychometric properties than the original ESS for individuals with physical or mental disabilities.

Clinical and functional patient characteristics predict medical needs in older patients at risk of functional decline.

BACKGROUND: The rising number of older multimorbid in-patients has implications for medical care. There is a growing need for the identification of factors predicting the needs of older patients in hospital environments. Our aim was to evaluate the use of clinical and functional patient characteristics for the prediction of medical needs in older hospitalized patients. METHODS: Two hundred forty-two in-patients (57.4% male) aged 78.4 ± 6.4 years, who were consecutively admitted to internal medicine departments of the University Hospital Essen between July 2015 and February 2017, were prospectively enrolled. Patients were assessed upon admission using the Identification of Seniors at Risk (ISAR) screening followed by comprehensive geriatric assessment (CGA). The CGA included standardized instruments for the assessment of activities of daily living (ADL), cognition, mobility, and signs of depression upon admission. In multivariable regressions we evaluated the association of clinical patient characteristics, the ISAR score and CGA results with length of hospital stay, number of nursing hours and receiving physiotherapy as indicators for medical needs. We identified clinical characteristics and risk factors associated with higher medical needs. RESULTS: The 242 patients spent [median(Q1;Q3)]:9.0(4.0;16.0) days in the hospital, needed 2.0(1.5;2.7) hours of nursing each day, and 34.3% received physiotherapy. In multivariable regression analyses including clinical patient characteristics, ISAR and CGA domains, the factors age (ß = - 0.19, 95% confidence interval (CI) = - 0.66;-0.13), number of admission diagnoses (ß = 0.28, 95% CI = 0.16;0.41), ADL impairment (B = 6.66, 95% CI = 3.312;10.01), and signs of depression (B = 6.69, 95% CI = 1.43;11.94) independently predicted length of hospital stay. ADL impairment (B = 1.14, 95%CI = 0.67;1.61), cognition impairment (B = 0.57, 95% CI = 0.07;1.07) and ISAR score (ß =0.26, 95% CI = 0.01;0.28) independently predicted nursing hours. The number of admission diagnoses (risk ratio (RR) = 1.06, 95% CI = 1.04;1.08), ADL impairment (RR = 3.54, 95% CI = 2.29;5.47), cognition impairment (RR = 1.77, 95% CI = 1.20;2.62) and signs of depression (RR = 1.99, 95% CI = 1.39;2.85) predicted receiving physiotherapy. CONCLUSION: Among older in-patients at risk for functional decline, the number of comorbidities, reduced ADL, cognition impairment and signs of depression are important predictors of length of hospital stay, nursing hours, and receiving physiotherapy during hospital stay.

[Treatment of insomnia in old age]. / Therapie der Insomnie im höheren Lebensalter.

Insomnia is one of the most frequent health disorders in old age. It causes suffering and numerous health problems. Therefore, treatment is often indicated. Behavioral therapy is the treatment of choice even in older individuals. In addition, light therapy also has an important role. Pharmacological treatment measures are less well studied, the benefits in long-term use are unclear and should only be applied in the short term to reduce suffering as well as being integrated into a comprehensive treatment concept.

Assessment of sleep and sleep disorders in geriatric patients.

Sufficient and refreshing sleep is important for good health, physical and cognitive functioning as well as quality of life. An assessment of sleep quality and sleep disorders is therefore mandatory in geriatric patients. Despite a variety of clinical assessment tools for screening and diagnosing sleep disorders, only some of them have been validated in older subjects and nearly none in geriatric patients or in individuals with dementia. Therefore, the aim of this review is to present a concise overview of assessment tools for sleep disorders that are widely used in sleep medicine and to briefly discuss the suitability and limitations in geriatric patients and subjects with dementia.

Health outcome of older hospitalized patients in internal medicine environments evaluated by Identification of Seniors at Risk (ISAR) screening and geriatric assessment.

BACKGROUND: Hospitals are in need of valid and economic screening and assessment tools that help identifying older patients at risk for complications which require intensified support during their hospital stay. METHODS: Five hundred forty-seven internal medicine in-patients (mean age 78.14 ± 5.96 years; 54.7% males) prospectively received Identification of Seniors at Risk (ISAR) screening. If screening results were positive (ISAR score ≥ 2), a comprehensive geriatric assessment (CGA) was performed. We explored sensitivity and specificity of different ISAR and CGA cutoffs. Further, we analyzed the risk of falls and how patients got discharged from hospital. RESULTS: ISAR+/CGA abnormal patients spent more days in hospital (16.1 ± 14.5), received more nursing hours per day (3.0 ± 2.3), more hours of physiotherapy during their hospital stay (2.2 ± 3.2), and had more falls (10.1%) compared to ISAR+/CGA normal (10.9 ± 12.3, 2.0 ± 1.2, 1.2 ± 4.3, and 2.8%, respectively, all p ≤ 0.016) and ISAR- (9.6 ± 11.5, 2.3 ± 4.5, 0.7 ± 2.0, and 2.2%, respectively, all p ≤ 0.002) patients. ISAR+/CGA abnormal patients terminated their treatment regularly with being discharged back home less often (59.6%) compared to ISAR+/CGA normal (78.5%, p = 0.002) and ISAR- (78.2%, p = 0.056) patients. ISAR cutoff≥2 and CGA defined as abnormal in case of impairment of ADL plus another CGA domain achieved best sensitivity/specificity. CONCLUSIONS: Abnormal geriatric risk screening and assessment are associated with longer hospital stay and higher amount of nursing and physiotherapy during hospital stay, greater risk of falling, and a lower percentage of successfully terminated treatment in older in-patients.

Changes in prescription patterns in older hospitalized patients: the impact of FORTA on disease-related over- and under-treatments.

PURPOSE: Physicians often face difficulties in choosing appropriate medications for multimorbid older people. The FORTA (Fit for the Aged) classification (A: absolutely, B: beneficial, C: careful, D: don't) was proposed as a clinical tool for improving the quality of drug treatment in the aged. As an implicit tool, FORTA has been shown to aid medication optimization and improve clinical end points in the VALFORTA trial. In this prospective randomized controlled study, 207 older hospitalized patients received standard geriatric treatment and 202 patients received FORTA-guided treatment. METHODS: Here, changes of drug prescriptions at the anatomical-therapeutic-chemical system (ATC) level were evaluated separately for important diagnoses in descriptive analyses; over- and under-treatment rates were compared between groups. RESULTS: At the individual drug/drug class level related to all important diagnoses, the application of FORTA significantly improved under-treatments for 12 drugs/drug classes (e.g., ACE inhibitors to treat arterial hypertension) and over-treatments for 7 drugs/drug classes (e.g., proton pump inhibitors to treat gastroesophageal reflux disease). CONCLUSIONS: FORTA representing the first combined positive/negative labeling approach at the individual drug level aids the optimization of drug treatment in older people as detected for drugs/drug classes at the ATC level in important indications. FORTA is effective in addressing over- and under-treatments even if analyzed for smaller subgroups of VALFORTA.

Pain and sleep : A bidirectional relationship.

Disturbed sleep and persistent pain are common in old people. Persistent pain has a well proven impact on sleep but the relationship between both phenomena is bidirectional since disturbed sleep affects pain perception by lowering the pain threshold. An optimal disease management takes both phenomena into account.

Sleep in older adults and in subjects with dementia.

The neuronal structures for the regulation of sleep and wakefulness are located in the brain. This complex network is vulnerable to numerous factors, most importantly neurodegenerative diseases and drugs. The macrostructure and microstructure of sleep change with age. These changes are more pronounced in subjects with dementia. Sleep disorders in subjects with dementia may be independent of dementia or caused by dementia. Furthermore, epidemiological studies reveal that sleep disorders per se may induce dementia by reduction of cerebral clearance of beta-amyloids. The population attributable risk (PAR) of sleep disturbances to the incidence of dementia is estimated to be about 15%; therefore, management of sleep disturbances in older adults and subjects with dementia gives the opportunity of an impact on incidence and course of dementia. Sleep history should be taken from each individual and obvious sleep disturbances, especially sleep apnea, should be managed according to current guidelines. Future studies that concern the incidence and the management of dementia must take into account sleep and sleep disturbances.

Principles of practice parameters for the treatment of sleep disordered breathing in the elderly and frail elderly: the consensus of the International Geriatric Sleep Medicine Task Force.

Sleep disordered breathing (SDB) is a leading cause of morbidity worldwide. Its prevalence increases with age. Due to the demographic changes in industrial societies, pulmonologists and sleep physicians are confronted with a rapidly growing number of elderly SDB patients. For many physicians, it remains unclear how current guidelines for SDB management apply to elderly and frail elderly patients. The goal of this consensus statement is to provide guidance based on published evidence for SDB treatment in this specific patient group.Clinicians and researchers with expertise in geriatric sleep medicine representing several countries were invited to participate in a task force. A literature search of PubMed from the past 12 years and a systematic review of evidence of studies deemed relevant was performed.Recommendations for treatment management of elderly and frail elderly SDB patients based on published evidence were formulated via discussion and consensus.In the last 12 years, there have been surprisingly few studies examining treatment of SDB in older adults and even fewer in frail older adults. Studies that have been conducted on the management of SDB in the older patient population were rarely stratified for age. Studies in SDB treatment that did include age stratification mainly focused on middle-aged and younger patient groups. Based on the evidence that is available, this consensus statement highlights the treatment forms that can be recommended for elderly SDB patients and encourages treatment of SDB in this large patient group.

VALFORTA: a randomised trial to validate the FORTA (Fit fOR The Aged) classification.

TRIAL DESIGN: to further validate the FORTA (Fit fOR The Aged) concept, a bicentric randomised, controlled trial was run in two geriatric clinics. METHODS: patients (≥65 years, ≥3 drugs or ≥60 years, ≥6 drugs) with three relevant diseases and hospitalisation for ≥5 days were randomised. In the intervention, but not the control group, a FORTA team instructed ward physicians on FORTA. FORTA is the first positive/negative listing approach labelling medications used to treat chronic illnesses in older patients from A (indispensable), B (beneficial), C (questionable) to D (avoid). The primary end point was the FORTA score: sum of medication errors classified as over-, under- and mistreatment. Consecutive patients were randomised to the intervention and control ward; outcome assessment was blinded. RESULTS: four hundred and nine patients (age 81.5 years, 64% female, hospitalisation 17.4 days) were included. The primary end point was significantly (P < 0.0001) more reduced in the intervention versus control groups (2.7 ± 2.25 versus 1 ± 1.8, mean ± SD, intergroup comparison of admission/discharge differences). Over- and under-treatment scores and use of A (increase) and D (decrease) drugs were significantly improved (P < 0.01). The total number of adverse drug reactions (ADRs) was significantly reduced by FORTA (P < 0.05, number needed to treat is 5). Activities of daily living and renal failure improved significantly (P < 0.05). Blood pressure remained constant in the intervention, but decreased significantly in the control group. CONCLUSION: applying FORTA to hospitalised geriatric patients leads to improvement of medication quality and may improve secondary clinical end points (e.g. ADRs). The concept is amenable to successful communication and implementation. Registration (DRKS-ID): DRKS00000531. FUNDING: DFG-German Research Foundation (WE 1184/15-1).
