Effects of medication management in geriatric patients who have fallen: results of the EMMA mixed-methods study.

BACKGROUND: comprehensive medication management (CMM) can reduce medication-related risks of falling. However, knowledge about inter-individual treatment effects and patient-related barriers remains scarce. OBJECTIVE: to gain in-depth insights into how geriatric patients who have fallen view their medication-related risks of falling and to identify effects and barriers of a CMM in preventing falls. DESIGN: complementary mixed-methods pre-post study, based on an embedded quasi-experimental model. SETTING: geriatric fracture centre. METHODS: qualitative, semi-structured interviews framed the CMM intervention, including a follow-up period of 12 weeks. Interviews explored themes of falling, medication-related risks, post-discharge acceptability and sustainability of interventions using qualitative content analysis. Optimisation of pharmacotherapy was assessed via changes in the weighted and summated Medication Appropriateness Index (MAI) score, number of fall-risk-increasing drugs (FRID) and potentially inappropriate medications (PIM) according to the Fit fOR The Aged and PRISCUS lists using parametric testing. RESULTS: thirty community-dwelling patients aged ≥65 years, taking ≥5 drugs and admitted after an injurious fall were recruited. The MAI was significantly reduced, but number of FRID and PIM remained largely unchanged. Many patients were open to medication reduction/discontinuation, but expressed fear when it came to their personal medication. Psychosocial issues and pain increased the number of indications. Safe alternatives for FRID were frequently not available. Psychosocial burden of living alone, fear, lack of supportive care and insomnia increased after discharge. CONCLUSION: as patients' individual attitudes towards trauma and medication were not predictable, an individual and longitudinal CMM is required. A standardised approach is not helpful in this population.

Combined systematic screening for malnutrition and dysphagia in hospitalized older adults: a scoping review.

BACKGROUND: Dysphagia affects about 40% of patients admitted to acute geriatric wards, as it is closely associated with diseases that rise in prevalence with advancing age, such as stroke, Parkinson's disease, and dementia. Malnutrition is a highly associated predictive factor of dysphagia as well as one of the most common symptoms caused by dysphagia. Thus, the two conditions may exist simultaneously but also influence each other negatively and quickly cause functional decline especially in older adults. The purpose of this review was to determine whether institutions have established a protocol combining screenings for dysphagia and malnutrition on a global scale. If combined screening protocols have been implemented, the respective derived measures will be reported. METHODS: A scoping review was conducted. A systematic database search was carried out in January and February 2024. Studies were included that examined adult hospitalized patients who were systematically screened for dysphagia and malnutrition. The results were managed through the review software tool Covidence. The screening of titles and abstracts was handled independently by two reviewers; conflicts were discussed and resolved by consensus between three authors. This procedure was retained for full-text analysis and extraction. The extraction template was piloted and revised following feedback prior to extraction, which was carried out in February 2024. RESULTS: A total of 2014 studies were found, 1075 of which were included for abstract screening, 80 for full text screening. In the end, 27 studies were extracted and reported following the reporting guideline PRISMA with the extension for Scoping Reviews. CONCLUSION: Most of the studies considered the prevalence and association of dysphagia and malnutrition with varying outcomes such as nutritional status, pneumonia, oral nutrition, and swallowing function. Only two studies had implemented multi-professional nutrition teams.

[Assessment of cognition: dementia and delirium : In consideration of the AWMF guidelines 038-013 and 084-002LG]. / Assessment der Kognition: Demenz und Delir : Unter Berücksichtigung der AWMF-Leitlinien 038-013 und 084-002LG.

Cognitive disorders are multifaceted and the range of neuropsychological instruments is correspondingly extensive; however, most examiners have to limit themselves to a small selection in order to master them safely. In geriatric patients the various forms and stages of dementia dominate. Delirium must be distinguished from these as an acute life-threatening event. The personal and external medical history as well as clinical observation are the first steps in the assessment of cognition; the selection of test procedures is graduated and bears the patient's benefit in mind. When compiling a toolbox for use in one's own field of work, in addition to instruments focusing on different degrees of severity, alternatives should also be considered for use in the presence of comorbidities that reduce the validity (visual, hearing and fine motor disorders) and the examination situation should be taken into account.

[Prevention of ischemic stroke in old age]. / Prävention des ischämischen Schlaganfalls im Alter.

Stroke is one of the main causes of permanent disability and death and the risk increases with age. Primary and secondary prevention therefore have a high priority. The treatment of risk factors, such as high blood pressure, diabetes mellitus and hyperlipidemia is just as important as anticoagulation in atrial fibrillation, in addition to optimization of lifestyle and diet. Platelet function inhibitors play a role in the prophylaxis of recurrence, carotid surgery and stenting are used in selected patients. There is little study evidence for old people, individualized treatment planning takes functional status and comorbidities into account.

Pulse-echo ultrasound measurement in osteoporosis screening: a pilot study in older patients.

BACKGROUND: A mere 25% of patients who need treatment for osteoporosis receive appropriate therapy, partly due to the time-consuming and stressful diagnostic workup for older patients with functional decline. AIMS: The purpose of the present study was to investigate the accuracy of pulse-echo ultrasound measurement of the lower leg for the detection of osteoporosis in older patients, and evaluate the effect of a proposed diagnostic algorithm. METHODS: Cortical thickness and the so-called density index (DI) were measured prospectively on the lower leg with a pulse-echo ultrasound (PEUS) device. The accuracy of the device was compared with dual-energy X-ray absorptiometry (DXA) of the hip. We calculated algorithms combining FRAX® scores and PEUS measures as a guide for specific treatment of osteoporosis. RESULTS: Three hundred and thirty-three patients aged on average 81 years (82.1% women, 275/333) were included in the study. The sensitivity of the ultrasound device versus DXA for the detection of osteoporosis was 94.4% (84/89), and the specificity was 59% (144/247). The gender-specific sensitivity was 96.2% (75/78) for women and 81.8% (9/11) for men. DISCUSSION: Clinical decisions for the specific treatment of osteoporosis could be based on the proposed algorithm, without additional DXA measurements, in 90.9% (303/333) of the patients. CONCLUSION: Older patients with a similar risk profile as in our study population may benefit from PEUS, as it is a non-invasive, cost-effective, and efficient diagnostic tool with high accuracy in screening patients for osteoporosis and the risk of fractures.

Prevalence of Subclinical Cardiovascular Disease in Patients with Non-Alcoholic-Fatty Liver Disease: Analysis of the Paracelsus 10.000 Cohort Study.

BACKGROUND: In patients with non-alcoholic fatty liver disease (NAFLD) cardiovascular diseases are more often the cause of death than the liver disease itself. However, the prevalence of atherosclerotic manifestations in individuals with NAFLD is still uncertain. This study aimed to explore the association between NAFLD and coronary artery calcification (CAC) in a Central European population. METHODS: A total of 1,743 participants from the Paracelsus 10,000 study were included. The participants underwent CAC scoring and were assessed for fatty liver index (FLI), fibrosing non-alcoholic steatohepatitis Index (FNI) and fibrosis-4 index (FIB-4 score), which are indicators for steatosis and fibrosis. Multivariable logistic regression models were calculated. RESULTS: Results revealed an association between liver steatosis/fibrosis and CAC. A FLI > 60 was associated with higher odds of NAFLD (OR 3.38, 95% CI: 2.61-4.39, p < 0.01) and increased prevalence of CAC-Score >300 compared to FLI <30 (9% vs. 3%, p < 0.01), even after adjusting for traditional cardiometabolic risk factors. While the crude odds ratios of the FIB-4 scores ≥ 1.3 and FNI score were significantly associated with increased odds of CAC, they became non-significant after adjusting for age, sex, and MetS. CONCLUSION: This study reveals a significant association between NAFLD and CAC. The findings suggest that assessing liver fat and fibrosis could enhance assessment of cardiovascular risk, but further research is needed to determine whether hepatic fat plays an independent role in the development of atherosclerosis and whether targeting liver steatosis can mitigate vascular risk.

[Assessment tools for palliative care needs in patients with heart failure in general practice]. / Assessment-Tools zur Identifizierung eines Palliativbedarfes bei Herzinsuffizienzpatienten in der allgemeinmedizinischen Praxis.

Palliative care of patients with non-oncological, chronic diseases is for the most part achieved by general practicioners (GP). Currently however standardized questionnaires are barely used by GPs to determine the demand. It is far more an intuitive, individual decision, at what time and to what extend a palliative treatment takes place at home. Based on an example of a patient with chronic heart failure, it's determined, if and with which assessment-tools the need for a (specialised) palliative care in general medicine can be detected.

Delirium in geriatric patients.

Delirium is the most common acute disorder of cognitive function in older patients. Delirium is life threatening, often under-recognized, serious, and costly. The causes are multifactorial, with old age and neurocognitive disorders as the main risk factors. Etiologies are various and multifactorial, and often related to acute medical illness, adverse drug reactions, or medical complications. To date, diagnosis is clinically based, depending on the presence or absence of certain features. In view of the multifactorial etiology, multicomponent approaches seem most promising for facing patients' needs. Pharmacological intervention, neither for prevention nor for treatment, has been proven effective unanimously. This article reviews the current clinical practice for delirium in geriatric patients, including etiology, pathophysiology, diagnosis, prognosis, treatment, prevention, and outcomes.

[Atypical Parkinson's syndrome in old age]. / Atypische Parkinson-Syndrome im Alter.

Atypical Parkinson syndromes represent a neuropathologically heterogeneous group and include the clinical entities dementia with Lewy bodies (DLB), multiple system atrophy (MSA), progressive supranuclear palsy (PSP), and corticobasal degeneration (CBD). The DLB and MSA are characterized by deposition of the protein alpha-synuclein (synucleinopathy), PSP and CBD are characterized by deposition of tau protein, often in the form of neurofibrillary tangles in nerve and glial cells (tauopathy). Misfolding and aggregation of the aforementioned proteins causes degeneration of the affected cell populations but the disease also spreads to anatomically neighboring brain regions, thus contributing to disease progression. The clinical characteristics (poor response to dopaminergic treatment, ataxia, apraxia, vertical gaze palsy and rapid progression) enable a differentiation from idiopathic Parkinson's disease.

The Prospective Studies of Atherosclerosis (Proof-ATHERO) Consortium: Design and Rationale.

Atherosclerosis - the pathophysiological mechanism shared by most cardiovascular diseases - can be directly or indirectly assessed by a variety of clinical tests including measurement of carotid intima-media thickness, carotid plaque, -ankle-brachial index, pulse wave velocity, and coronary -artery calcium. The Prospective Studies of Atherosclerosis -(Proof-ATHERO) consortium (https://clinicalepi.i-med.ac.at/research/proof-athero/) collates de-identified individual-participant data of studies with information on atherosclerosis measures, risk factors for cardiovascular disease, and incidence of cardiovascular diseases. It currently comprises 74 studies that involve 106,846 participants from 25 countries and over 40 cities. In summary, 21 studies recruited participants from the general population (n = 67,784), 16 from high-risk populations (n = 22,677), and 37 as part of clinical trials (n = 16,385). Baseline years of contributing studies range from April 1980 to July 2014; the latest follow-up was until June 2019. Mean age at baseline was 59 years (standard deviation: 10) and 50% were female. Over a total of 830,619 person-years of follow-up, 17,270 incident cardiovascular events (including coronary heart disease and stroke) and 13,270 deaths were recorded, corresponding to cumulative incidences of 2.1% and 1.6% per annum, respectively. The consortium is coordinated by the Clinical Epidemiology Team at the Medical University of Innsbruck, Austria. Contributing studies undergo a detailed data cleaning and harmonisation procedure before being incorporated in the Proof-ATHERO central database. Statistical analyses are being conducted according to pre-defined analysis plans and use established methods for individual-participant data meta-analysis. Capitalising on its large sample size, the multi-institutional collaborative Proof-ATHERO consortium aims to better characterise, understand, and predict the development of atherosclerosis and its clinical consequences.

Evaluation of baseline fracture risk in younger postmenopausal women with breast cancer using different risk assessment methods.

OBJECTIVE: Controversy exists about the impact of bone mineral density (BMD) and fracture risk in newly diagnosed patients with breast cancer (BC). It is presumed that there are differences in BMD between women with BC and healthy controls. BMD is therefore considered as a potential marker to predict BC risk. This study was conducted to investigate the association of BMD, trabecular bone score (TBS) and fracture risk in younger postmenopausal women with hormone responsive BC. METHODS: Overall, 343 women were examined. Women with BC were matched to a control group of the general population. Forty-nine women and fifty-nine controls were included in the final analysis. All subjects underwent dual energy x-ray absorptiometry (DXA) of the lumbar spine, femoral neck, and the total hip to evaluate bone mineral density. The 10-year fracture risk for a major osteoporotic fracture was assessed using the FRAX-score and the TBS-adjusted FRAX-Score, respectively. RESULTS: Lumbar and femoral neck BMD were similar in BC patients and controls. No difference was found for TBS of the spine (1.38 ± 0.1 vs.1.36 ± 0.09) in the BC and the control group, respectively (p = 0.19). The 10- year probability for a major osteoporotic fracture (MoF) or femoral neck (FN) fracture was 6.1 (± 2.6%) and 0.9 (± 1.2%) in the BC group vs. 6.7 (± 3.5%) (p = 0.33) and 0.9 (± 1.1%) (p = 0.73) in the control group. CONCLUSION: Postmenopausal women younger than 60 years with breast cancer do not show any differences in baseline BMD, TBS, or TBS adjusted FRAX in comparison to controls.

Comparison of visual, automatic and semiautomatic methods to determine ventilatory indices in 50 to 60 years old adults.

The aim of this study was to compare different methods of detecting ventilatory indices (VI) and to investigate the impact of cardiorespiratory fitness (CRF) level on VI detection. Fifty females and fifty males completed a graded exercise test until volitional exhaustion with continuous gas-exchange measurement. The first and second ventilatory indices (VI-1, VI-2) were detected through different single automatic methods and through a semiautomatic method which combines visual and automatic detection methods. Additionally, the VIs were detected visually by two experts which served as the study specific gold standard. When comparing the semiautomatic method at VI-1 (intraclass correlation coefficients (ICC) 0.88 [0.81, 0.92], Bland-Altman bias ± limits of agreement (LoA) 55 ± 334 ml O2 · min-1) and VI-2 (ICC 0.97 [0.96, 0.98], LoA 1 ± 268 ml O2 · min-1) to the visually detected VI, high levels of agreements and no significant differences were found. This was not the case for any of the other automatic methods. Additionally, we couldn't find any relevant differences regarding the CRF level.We therefore concluded that the semiautomatic detection method should be used for VI detection, as results are more accurate than in any of the single-automatic methods.Abbreviations: CPET: cardiopulmonary exercise test; CRF: Cardiorespiratory fitness; VO2peak: peak oxygen uptake; VI-1: first ventilatory indices; VI-2: second ventilatory indices; LoA: Bland-Altman bias ± limits of agreement; ICC: intraclass correlation coefficient.

What do geriatric patients experience during an episode of delirium in acute care hospitals? : A qualitative study.

BACKGROUND: Predispositions and triggers for delirium, such as noxious agents are known and behavior can be monitored; however, there is little to no information available regarding the experience of patients during delirium episodes. Not much is known about a person's world of experiences, which therefore mostly remains as a sort of black box. OBJECTIVE: This study was motivated by the following question: "What do (Austrian) geriatric patients experience during an episode of delirium in an acute care hospital?" The main objective of this article is to present little snippets from the experiences and to allow geriatric patients to speak for themselves. PATIENTS AND METHODS: From 2013 to 2016 interviews were carried out within the framework of a qualitative investigation. For data collection narrative interviews according to Fritz Schütze were employed and 10 interviews were conducted in a hospital setting with German-speaking Austrian patients aged between 75 and 90 years (mean age 80.2 years; 7 female and 3 male). The individual interviews lasted between 60 and 120 min. Primary data in the form of individual interpretation and interpretation groups from interview transcripts were marked and coded according to Mayring. RESULTS: All patients who participated in the interviews subjectively recognized delirium as a negative experience. The data analysis led to three main categories with subcategories: changes in sensory perception, extraordinarily strong emotions and memories. It is important to differentiate between two very different types of memories: firstly, personal fate or life changes and secondly, those regarding experiences of war. CONCLUSION: Scandinavian and Anglo-American literature describe different categories, such as a change in reality, strong emotions and dramatic episodes in the experience of delirium, which can be transferred to Austria. Others consider the biography of each individual patient in context with the sociocultural history of Austria, especially following developments after 1940.

Polypharmacy in palliative care-COPD and multimorbidity : A case report.

This is the case report of an 80-year-old woman with advanced chronic obstructive pulmonary disease (COPD), multimorbidity and frailty. Despite regular critical re-evaluation of on-going medication, a significant reduction of prescribed medication was not achieved up until the patient's terminal phase, and this may have contributed to several episodes of delirium. It was particularly difficult to reduce the number of prescribed drugs due to cardiovascular, endocrinologic, orthopaedic, neurologic, psychiatric and pulmonary comorbidities. Probable drug-drug interactions and side effects were repeatedly observed. This case report aims to describe a dilemma frequently encountered in the care of patients with progressed pulmonary disease in the context of frailty and multimorbidity.

[Doping for the brain]. / Doping für das Gehirn.

The enhancement of physical and cognitive abilities (i. e. concentration, vigilance, memory) has always been desirable for humans. The term pharmacological neuroenhancement refers to the use of legal or nonprescription psychoactive substances by healthy subjects with the intention of cognitive enhancement. To give the most prominent example, caffeine serves worldwide as a natural stimulant. Brain doping, however, specifies the use of illegal substances or prescription drugs beyond approval with the purpose of cognitive enhancement. Only amphetamines, methylphenidate and modafinil have significant effects on attentiveness, concentration and alertness, whereas other substances, such as anti-dementia drugs or anti-depressants failed to demonstrate cognitive enhancement in healthy subjects.

Electroencephalogram alpha asymmetry in geriatric depression : Valid or vanished?

BACKGROUND: A correlation between asymmetry in electroencephalographs (EEG) and depression has been demonstrated in many studies. To the best of our knowledge there are no studies including oldest old geriatric patients. OBJECTIVE: The objective of this study was to evaluate whether frontal and parietal alpha asymmetry can be used to differentiate between depressed and control patients in a cohort sample with a mean age of 80 years. MATERIAL AND METHODS: Differences in the EEG were investigated in 39 right-handed female geriatric patients (mean age 80 years) with respect to frontal alpha asymmetry (FAA) and parietal alpha asymmetry (PAA) in depression (n = 14), depression combined with anxiety (n = 11) and normal controls (n = 14) as assessed with the hospital anxiety and depression scale (HADS). Band power was calculated for alpha 1 (6.9-8.9 Hz), alpha 2 (8.9-10.9 Hz) and alpha 3 bands (10.9-12.9 Hz). Furthermore, correlations between frontal and parietal alpha asymmetry and the geriatric depression scale (GDS), the HADS and the mini mental state examination (MMSE) were calculated. RESULTS: A differentiation between the three groups was not possible with FAA and PAA. Significant correlations were found between PAA alpha 3 band and anxiety and depression. CONCLUSION: The alpha asymmetry in EEG seemed to disappear with age. Correlations between PAA and anxiety and depression were found. The results are in line with the right (hemisphere) hemi-aging hypothesis.

EEG beta 2 power as surrogate marker for memory impairment: a pilot study.

BACKGROUND: Memory deficits are dominant in dementia and are positively correlated with electroencephalographic (EEG) beta power. EEG beta power can predict the progression of Alzheimer´s (AD) as early as at the stage of mild cognitive impairment (MCI) and could possibly be used as surrogate marker for memory impairment. The objective of this study is to analyze the relationship between frontal and parietal EEG beta power and memory-test outcome. Frontal and parietal beta power is analyzed for a resting state and an eyes-closed backward counting condition and related to memory impairment parameters. METHODS: A total of 28 right-handed female geriatric patients (mean age = 80.6) participated voluntarily in this study. Beta 1 (12.9-19.2 Hz) and beta 2 (19.2-32.4 Hz) EEG power at F3, F4, Fz, P3, P4, and Pz are correlated with immediate wordlist recall, delayed wordlist recall, recognition of learned words, and delayed figure recall. For classification between impaired and intact memory, we calculated a binary logistic regression model with memory impairment as a dependent variable and beta 2 power as an independent variable. RESULTS: We found significant positive correlations between frontal and parietal beta power and delayed memory recall. A significant correlation (Bonferroni correction, p < 0.05) was found at F4 beta 2 during backward counting. The binary logistic regression model with F4 beta 2 power during the counting condition as a predictor yielded a sensitivity of 76.9% (95% CI) and a specificity of 73.3% (95% CI) for classifying patients into "verbal-memory impaired" and "intact." CONCLUSIONS: EEG beta 2 power recorded during a backward counting condition with eyes closed can be used as surrogate marker for verbal memory impairment in geriatric patients. Antidepressant treatment was correlated with EEG data in resting state but not in counting condition. Further studies are necessary to verify the results of this pilot study.

[Polyneuropathy in the elderly]. / Polyneuropathie im Alter.

The peripheral nervous system is subject to changes during the ageing process, e. g. deep tendon reflexes decrease, as does proprioception. Polyneuropathies, on the other hand, need to be distinguished from age-related changes as independent diseases with etiologies similar to those at younger ages. Etiologies includes metabolic disorders, primary inflammatory polyneuropathies, and systemic disorders. Neuropathies associated with diabetes, malignancy, and monoclonal gammopathies appear to be more common in older patients. Using a systematic approach, it is possible to establish a specific diagnosis in the majority of cases. Since polyneuropathies contribute to reduced mobility in the elderly, an assessment of functional skills is mandatory. Polyneuropathy therapy is primarily based on the treatment of underlying conditions and neuropathic pain management. Physiotherapy and rehabilitation target pain relief and maintaining activities of daily living.

Heme oxygenase-1 gene promoter microsatellite polymorphism is associated with progressive atherosclerosis and incident cardiovascular disease.

OBJECTIVE: The enzyme heme oxygenase-1 (HO-1) exerts cytoprotective effects in response to various cellular stressors. A variable number tandem repeat polymorphism in the HO-1 gene promoter region has previously been linked to cardiovascular disease. We examined this association prospectively in the general population. APPROACH AND RESULTS: Incidence of stroke, myocardial infarction, or vascular death was registered between 1995 and 2010 in 812 participants of the Bruneck Study aged 45 to 84 years (49.4% males). Carotid atherosclerosis progression was quantified by high-resolution ultrasound. HO-1 variable number tandem repeat length was determined by polymerase chain reaction. Subjects with ≥32 tandem repeats on both HO-1 alleles compared with the rest of the population (recessive trait) featured substantially increased cardiovascular disease risk (hazard ratio [95% confidence interval], 5.45 [2.39, 12.42]; P<0.0001), enhanced atherosclerosis progression (median difference in atherosclerosis score [interquartile range], 2.1 [0.8, 5.6] versus 0.0 [0.0, 2.2] mm; P=0.0012), and a trend toward higher levels of oxidized phospholipids on apolipoprotein B-100 (median oxidized phospholipids/apolipoprotein B level [interquartile range], 11364 [4160, 18330] versus 4844 [3174, 12284] relative light units; P=0.0554). Increased cardiovascular disease risk in those homozygous for ≥32 repeats was also detected in a pooled analysis of 7848 participants of the Bruneck, SAPHIR, and KORA prospective studies (hazard ratio [95% confidence interval], 3.26 [1.50, 7.33]; P=0.0043). CONCLUSIONS: This study found a strong association between the HO-1 variable number tandem repeat polymorphism and cardiovascular disease risk confined to subjects with a high number of repeats on both HO-1 alleles and provides evidence for accelerated atherogenesis and decreased antioxidant defense in this vascular high-risk group.

Pain treatment for nursing home residents differs according to cognitive state - a cross-sectional study.

BACKGROUND: Communication skills are known to decrease with advancing cognitive impairment. Analgesic treatment in long-term care may be deficient due to the residents' impaired ability to communicate their pain and needs. Undertreated pain frequently leads to rising BPSD in residents with cognitive impairment, resulting in a treatment with antipsychotics. Aim of this study was the analysis of differences in assessment and pharmacological treatment of pain in nursing home residents relative to their cognitive state and ability to articulate pain. METHODS: Data stems from the baseline of a non-experimental pre-post-study in 12 Austrian nursing homes. Residents' pain prevalence in relation to pain assessment and cognitive decline was assessed, data on medical diagnoses and prescriptions were retrieved from the nursing homes' documentation (n = 425). Residents were first divided into two groups: Residents with MMSE ≥ 18 were selected into group CUS (cognitively unimpaired/slightly impaired), residents with MMSE ≤ 17 were selected into group CI (cognitively moderately to severely impaired). CI residents were then sub-grouped according to their ability to communicate pain via the Verbal Rating Scale (VRS) (i.e. group CI-V, group CI-NV). Pain behavior of CI residents was assessed with a modified German version of PAINAD. Group differences were tested with ANOVA and H-test, 95 % confidence intervals were calculated and associations were tested with log-binomial regression. RESULTS: Pain prevalence in CI residents irrespective of their ability to communicate pain was 80 % and exceeded the CUS group prevalence significantly by 14 %. CI residents had significantly less analgesic prescriptions. Furthermore, CI residents have a significantly higher risk of getting no analgesics when in pain than CUS residents (CI-V: RR =2.6, CI-NV: RR =3.4). Use of antipsychotics was high in all groups (49 - 65 %) with more prescriptions in the cognitively impaired group. CONCLUSION: Results point toward an underuse of pain medication in cognitively impaired residents, especially those unable to communicate pain verbally. The implementation of standardized pain assessments adapted to the cognitive abilities of residents may foster the recognition of pain, warrant optimized pain management, reduce inadequate medication and consequently raise the chance of equally effective pain treatment regardless of cognitive state.
