Deprescribing of antidepressants: development of indicators of high-risk and overprescribing using the RAND/UCLA Appropriateness Method.

BACKGROUND: Antidepressants are first-line medications for many psychiatric disorders. However, their widespread long-term use in some indications (e.g., mild depression and insomnia) is concerning. Particularly in older adults with comorbidities and polypharmacy, who are more susceptible to adverse drug reactions, the risks and benefits of treatment should be regularly reviewed. The aim of this consensus process was to identify explicit criteria of potentially inappropriate antidepressant use (indicators) in order to support primary care clinicians in identifying situations, where deprescribing of antidepressants should be considered. METHODS: We used the RAND/UCLA Appropriateness Method to identify the indicators of high-risk and overprescribing of antidepressants. We combined a structured literature review with a 3-round expert panel, with results discussed in moderated meetings in between rounds. Each of the 282 candidate indicators was scored on a 9-point Likert scale representing the necessity of a critical review of antidepressant continuation (1-3 = not necessary; 4-6 = uncertain; 7-9 = clearly necessary). Experts rated the indicators for the necessity of review, since decisions to deprescribe require considerations of patient risk/benefit balance and preferences. Indicators with a median necessity rating of ≥ 7 without disagreement after 3 rating rounds were accepted. RESULTS: The expert panel comprised 2 general practitioners, 2 clinical pharmacologists, 1 gerontopsychiatrist, 2 psychiatrists, and 3 internists/geriatricians (total N = 10). After 3 assessment rounds, there was consensus for 37 indicators of high-risk and 25 indicators of overprescribing, where critical reviews were felt to be necessary. High-risk prescribing indicators included settings posing risks of drug-drug, drug-disease, and drug-age interactions or the occurrence of adverse drug reactions. Indicators with the highest ratings included those suggesting the possibility of cardiovascular risks (QTc prolongation), delirium, gastrointestinal bleeding, and liver injury in specific patient subgroups with additional risk factors. Overprescribing indicators target patients with long treatment durations for depression, anxiety, and insomnia as well as high doses for pain and insomnia. CONCLUSIONS: Explicit indicators of antidepressant high-risk and overprescribing may be used directly by patients and health care providers, and integrated within clinical decision support tools, in order to improve the overall risk/benefit balance of this commonly prescribed class of prescription drugs.

Diagnostic accuracy of the 'Dysphagia Screening Tool for Geriatric Patients' (DSTG) compared to Flexible Endoscopic Evaluation of Swallowing (FEES) for assessing dysphagia in hospitalized geriatric patients - a diagnostic study.

BACKGROUND: Oropharyngeal dysphagia is highly prevalent among hospitalized geriatric patients. The screening instruments used to date have been evaluated primarily in stroke patients. This diagnostic study aimed to validate a new screening instrument for oropharyngeal dysphagia, the 'Dysphagia Screening Tool for Geriatric Patients' (DSTG), as compared to one of the gold standards, flexible endoscopic evaluation of swallowing (FEES). MATERIALS AND METHODS: Geriatric inpatients admitted to five geriatric hospitals in Germany were consecutively evaluated using both DSTG and FEES in random order and by different evaluators blinded to the results of the other evaluation. In the FEES examination, a score of more than 3 on Rosenbek's Penetration Aspiration Scale was considered evidence of clinically relevant oropharyngeal dysphagia. Sensitivity, specificity and further measures of test performance were calculated for DSTG. RESULTS: The 53 volunteers recruited were on average 85 years of age, 56.6% were women. Twenty patients (37.7%) were diagnosed with dysphagia using FEES. Of these, 12 were screened as positive on DSTG. Of the 33 FEES negative patients, 4 tested positive on DSTG. The following test parameters were calculated for DSTG: sensitivity: 0.60, 95% confidence interval [0.39 ; 0.78], specificity 0.88 [0.73 ; 0.95], positive predictive value 0.75 [0.51 ; 0.90], negative predictive value 0.78 [0.63 ; 0.89], positive likelihood ratio 4.95 [1.85 ; 13.27], negative likelihood ratio 0.46 [0.26 ; 0.79]. In a receiver-operator characteristic (ROC) curve analysis, the area under the curve (AUC) was 0.77 [0.62 ; 0.91]. No adverse events occurred. CONCLUSION: The DSTG appears to be a valid instrument for screening of oropharyngeal dysphagia in geriatric inpatients.

Effectiveness of a multi-component community-based care approach for older people at risk of care dependency - results of a prospective quasi-experimental study.

BACKGROUND: Due to demographic changes, the elderly population in western countries is constantly growing. As the risk of functional decline and multimorbidity increases with age, health care systems need to face the challenge of high demand for health care services and related costs. Therefore, innovative health care approaches and geriatric screenings are needed to provide individualised care. This study aims to expand the state of research by investigating the effectiveness of a multi-component care approach for the elderly in a German community setting. METHODS: A prospective, quasi-experimental study was initiated by statutory health insurance (SHI) companies. The innovative care approach includes a geriatric assessment, a case and network management as well as digital supporting tools and was implemented at the Center for Geriatrics and Gerontology (Albertinen Haus, Hamburg-Eimsbuettel). Participants of the intervention were compared to matched controls recruited in comparable urban areas. The primary outcome measure was the progression in long-term care grade during the period of observation (21 months), which was analysed on the basis of SHI claims data. Secondary endpoints were morbidity, mortality and self-reported health-related quality of life (HRQoL) measured by SF-36. RESULTS: Overall, 2,670 patients (intervention group (IG) n=873; control group (CG) n=1,797) were analysed. Logistic regression analysis showed no statistically significant difference in progression of long-term care grade between IG and CG (Odds Ratio (OR)=1.054; 95% confidence interval (CI) 0.856-1.296; p-value=0.616). Differentiated analyses indicated an initial effect, which might be attributable to the geriatric assessment. However, an adapted regression model resulted in a reversed but even non-significant effect (OR=0.945; 95% CI 0.757-1.177; p-value=0.619). While secondary analyses of long-term care grade, mortality and HRQoL did not show intervention effects, a statistically significant relative change of 0.865 (95% CI 0.780, 0.960; p-value=0.006) in morbidity indicated a potential benefit for the IG. CONCLUSIONS: The analyses did not reveal a significant effect of the community-based intervention on the primary outcome and thus we are not able to recommend a transfer into SHI standard care. Tendencies in secondary analyses need to be proved in further research. TRIAL REGISTRATION: German Clinical Trials Register, retrospective registration on February 01, 2022 ( DRKS00027866 ).

[Development of a new screening instrument for screening of dysphagia in geriatric patients: the dysphagia screening tool geriatrics]. / Entwicklung eines neuen Screeninginstruments zum Screening auf Dysphagie bei geriatrischen Patienten: das Dysphagie Screening-Tool Geriatrie.

BACKGROUND: Oropharyngeal dysphagia is widespread in geriatric patients and is nearly always multicausal. It is often insufficiently recognized and leads to severe complications. The available and established screening tools all focus primarily on patients with neurological diseases, usually following a stroke. MATERIAL AND METHODS: The working group on dysphagia of the German Society of Geriatrics (DGG), which is comprised of physicians, speech and language therapists and dysphagia therapists, performed a literature review on dysphagia screening tools. Based on the results of the literature search and own experience, a new screening instrument suitable for geriatric patients was developed and agreed by the consensus group. RESULTS: The new screening instrument for the detection of oropharyngeal dysphagia in geriatric patients consists of three parts: 1) consciousness and posture control while sitting, 2) ability to swallow saliva and to cough as well as tongue motility and 3) the water swallowing test. The screening can be applied by trained medical personnel and can easily be integrated into everyday practice. CONCLUSION: The new screening tool is especially aimed at geriatric patients. It has advantages compared to previously recommended screening tests. Initial experiences with the instrument show good practicability and acceptance in geriatric teams. Further studies have to test the validity of the instrument.

Potentially inappropriate medication among people with dementia in eight European countries.

Objectives: to evaluate the frequency of potentially inappropriate medication (PIM) prescription among older people with dementia (PwD) from eight countries participating in the European study 'RightTimePlaceCare', and to evaluate factors and adverse outcomes associated with PIM prescription. Methods: survey of 2,004 PwD including a baseline assessment and follow-up after 3 months. Interviewers gathered data on age, sex, prescription of medication, cognitive status, functional status, comorbidity, setting and admission to hospital, fall-related injuries and mortality in the time between baseline and follow-up. The European Union(7)-PIM list was used to evaluate PIM prescription. Multivariate regression analysis was used to investigate factors and adverse outcomes associated with PIM prescription. Results: overall, 60% of the participants had at least one PIM prescription and 26.4% at least two. The PIM therapeutic subgroups most frequently prescribed were psycholeptics (26% of all PIM prescriptions) and 'drugs for acid-related disorders' (21%). PwD who were 80 years and older, lived in institutional long-term care settings, had higher comorbidity and were more functionally impaired were at higher risk of being prescribed two PIM or more. The prescription of two or more PIM was associated with higher chance of suffering from at least one fall-related injury and at least one episode of hospitalisation in the time between baseline and follow-up. Conclusions: PIM use among PwD is frequent and is associated with institutional long-term care, age, advanced morbidity and functional impairment. It also appears to be associated with adverse outcomes. Special attention should be paid to psycholeptics and drugs for acid-related disorders.

[List-based concepts in pharmacotherapy of older and geriatric patients]. / Listenbasierte Ansätze in der Arzneimitteltherapie bei älteren und geriatrischen Patienten.

Pharmacotherapy for older and geriatric patients is a challenge, especially because older and geriatric patients are particularly prone to adverse drug reactions and the evidence for drug use is limited for this patient group; therefore, several list-based recommendations have recently been developed in order to improve appropriate pharmacotherapy. These lists of recommendations differ in their criteria and the compilation of drugs, for example in terms of potentially inappropriate medication, drugs increasing the risk of falling and anticholinergic effects. This review highlights the characteristics of selected recently published lists, describes the concepts behind them and discusses the advantages and disadvantages of the individual approaches.

Sleep duration and quality in heart failure patients.

PURPOSE: Sleep-disordered breathing (SDB) is highly prevalent in patients with heart failure and reduced left ventricular ejection fraction (HF-REF). SDB is classified as predominant obstructive (OSA) or central (CSA) and may alter sleep duration, sleep quality, and quality of life. This study describes sleep quality and duration in well-characterized cohorts of these patients. METHODS: Two hundred fifty consecutive patients with HF-REF (NYHA class ≥II, ejection fraction ≤45%) underwent cardiac and pulmonary examination, plus full attended in-hospital overnight polysomnography (PSG). PSG recordings were performed according to current recommendations and underwent independent, blinded analysis at a core laboratory. RESULTS: Patients with HF-REF and CSA were older and had more impaired cardiac function compared to those with OSA. With respect to sleep parameters, patients with CSA spent more time in bed than those with OSA (468 ± 52 vs 454 ± 46 min, p = 0.021) while sleep efficiency was lower (67 ± 14 vs 72 ± 13% of total sleep time (TST), p = 0.008). In addition, CSA patients spent more time awake after sleep onset (101 ± 61 vs 71 ± 46 min, p = 0.001) and had more stage N1 (light) sleep (33 ± 19 vs 28 ± 16% of TST, p = 0.017). Overall, the proportion of sleep spent in N3 (slow-wave/deep) sleep in HF-REF patients with SDB was low (4.1 ± 6.3% of TST) compared with healthy adults. CONCLUSIONS: HF-REF patients with CSA compared to OSA have worse sleep efficiency and quality. This could result in less restorative sleep, changes in sympathovagal balance, and impaired resetting of important reflexes, which might contribute to worse cardiovascular outcomes in HF-REF patients with SDB.

Nocturnal hypoxaemia is associated with increased mortality in stable heart failure patients.

AIM: This study investigated the prognostic value of sleep-disordered breathing (SDB) in a large cohort of patients with heart failure with reduced left ventricular function (HF-REF), with focus on the role of nocturnal hypoxaemia. METHODS: This single-centre prospective cohort study enrolled patients with chronic stable HF-REF (NYHA ≥II) receiving guideline-based treatment. Unattended in-hospital polygraphy was performed to determine the apnoea-hypopnoea index (AHI). Pulse oximetry was used to determine hypoxaemic burden [time with oxygen saturation <90% (T90)], and all-cause mortality was recorded. RESULTS: Complete data were available for 963 of 1249 patients. At baseline, 58% of patients had moderate-to-severe SDB. The median follow-up was 7.35 years; 480 of 963 (49.8%) patients died. Mortality rate (per 100 person-years) was 8.1 [95% confidence interval (CI) 7.0-9.4] in patients with no or mild SDB, but 12.2 (95% CI 10.9-13.7) in moderate-to-severe SDB. Apnoea-hypopnoea index was significantly associated with time to death from any cause in a simple Cox model [hazard ratio (HR) 1.011, P < 0.001], but was no longer significant after adjustment for confounding factors (HR 1.005, P = 0.085). T90 was significantly (P < 0.001) associated with time to death from any cause even after adjustment for confounding factors. The risk of death increased by 16.1% (95% CI 8.6-24.2) per hour of T90. Five-year survival probabilities for patients in T90 quartiles 1, 2, 3, and 4 were 70, 63, 60, and 50%, respectively. CONCLUSION: Hypoxaemic burden was a robust and independent predictor of all-cause mortality in chronic stable HF-REF patients. Whether or not targeting nocturnal hypoxaemia is associated with beneficial effects on mortality in HF-REF patients remains to be determined.

Interactions between C-reactive protein and traditional risk factors in predicting mortality of older adults.

BACKGROUND: Elevated levels of C-reactive protein (CRP) are known to be associated with cardiovascular (CV) morbidity and mortality in older adults, however, there seems to be heterogeneity of this association across subsets of individuals. We aim to assess the effects of interactions between CRP and one of the following traditional CV risk factors regarding all-cause mortality in unselected elderly men and women: age, sex, body mass index, diabetes, and hypertension. PATIENTS AND METHODS: Three hundred and forty-four general practitioners all over Germany enrolled 6,817 unselected participants, aged 65 years or older, and performed thorough examinations, including CRP measurement at baseline (getABI study). All-cause mortality was determined in the following seven years. Cox regression analyses were done using uni- and multivariable models. RESULTS: At baseline 4,172 participants of this cohort had a CRP value of ≤ 3 mg/L (low level CRP group), 2,645 participants had a CRP value of > 3 mg/L (high level CRP group). The unadjusted hazard ratio for all-cause death of the high level CRP group compared to the low level CRP group was 1.49 (95 % confidence interval [95 %CI] 1.34 to 1.66). After adjustment for sex, age, education, peripheral artery disease/media sclerosis, other prior vascular events, smoking status, diabetes, systolic blood pressure, antihypertensive medication, body mass index, cholesterol, and statin use, the hazard ratio was 1.34 (95 %CI 1.20 to 1.50). Significant interactions with CRP were found for sex (adjusted hazard ratio 1.38, 95 %CI 1.11 to 1.72), age (0.75, 95 %CI 0.60 to 0.94), and baseline systolic blood pressure (0.64, 95 % CI 0.51 to 0.81). The interactions of CRP with body mass index and of CRP with diabetes were not significant. CONCLUSIONS: In older German adults, there seem to be effect modifications by age, sex, and arterial hypertension regarding the effect of CRP in the prediction of all-cause mortality.

The risk of peripheral artery disease in older adults - seven-year results of the getABI study.

BACKGROUND: To assess the risk of peripheral artery disease (PAD) in older adults and the contribution of traditional and novel risk factors to the incidence of PAD. PATIENTS AND METHODS: 344 general practitioners (GPs), trained by vascular specialists all over Germany, enrolled 6,880 unselected participants aged 65 years or older (getABI study). The onset of PAD was determined by a regression method in the course of repeated measurements of the ankle brachial index (ABI) over seven years. PAD onset was defined by the declining linear regression ABI line reaching 0.9 or by PAD symptoms. RESULTS: The cumulative PAD incidence over seven years was 12.9%, corresponding to an incidence rate of 20.3 per 1000 person years (95% confidence interval [95%CI] 18.8 to 21.7). Logistic regression analysis showed that traditional risk factors contributed significantly to the risk of PAD: current smoker status (odds ratio 2.65, 95%CI 2.08 to 3.37), diabetes (1.35, 95%CI 1.13 to 1.62), and low-density lipoprotein >130 mg/dl (1.26, 95%CI 1.07 to 1.48). Three novel risk factor candidates showed significant impact on PAD incidence: elevated sensitive C-reactive protein level (1.23, 95%CI 1.05 to 1.45), impaired estimated glomerular filtration rate (1.27, 95%CI 1.03 to 1.56), and elevated homocysteine level (1.19, 95%CI 1.01 to 1.41). CONCLUSIONS: Older adults in Germany have a PAD risk of 12.9% per seven years. Potentially modifiable traditional PAD risk factors yield high impact on PAD incidence. Novel risk factor candidates may contribute to the risk of PAD.

Pneumonia severity, comorbidity and 1-year mortality in predominantly older adults with community-acquired pneumonia: a cohort study.

BACKGROUND: In patients with community-acquired pneumonia (CAP), short-term mortality is largely dependent on pneumonia severity, whereas long-term mortality is considered to depend on comorbidity. However, evidence indicates that severity scores used to assist management decisions at disease onset may also be associated with long-term mortality. Therefore, the objective of the study was to investigate the performance of the pneumonia severity scores CURB-65 and CRB-65 compared to the Charlson Comorbidity Index (CCI) for predicting 1-year mortality in adults discharged from hospital after inpatient treatment for CAP. METHODS: From a single centre, all cases of patients with CAP treated consecutively as inpatients between 2005 and 2009 and surviving at least 30 days after admission were analysed. The patients' vital status was obtained from the relevant local register office. CURB-65, CRB-65 and CCI were compared using receiver operating characteristics (ROC) analysis. RESULTS: Of 498 cases analysed, 106 (21.3%) patients died within 1 year. In univariate analysis, age ≥65 years, nursing home residency, hemiplegia, dementia and congestive heart failure were significantly associated with mortality. CURB-65, CRB-65 and CCI were also all associated with mortality at 1 year. ROC analysis yielded a weak, yet comparable test performance for CURB-65 (AUC and corresponding 95% confidence interval [CI] for risk categories: 0.652 [0.598-0.706]) and CCI (AUC [CI]: 0.631 [0.575-0.688]; for CRB-65 0.621 [0.565-0.677] and 0.590 [0.533-0.646]). CONCLUSIONS: Neither CURB-65 or CRB-65 nor CCI allow excellent discrimination in terms of predicting longer term mortality. However, CURB-65 is significantly associated with long-term mortality and performed equally to the CCI in this respect. This fact may help to identify CAP survivors at higher risk after discharge from hospital.

Short-term mortality of adult inpatients with community-acquired pneumonia: external validation of a modified CURB-65 score.

OBJECTIVE: The management of community-acquired pneumonia (CAP) continues to be a challenge, especially in older people. To enable better risk stratification, a variation of the severity scores CRB-65 and CURB-65, called CURB-age, has been suggested. We compared the association between risk groups as defined by the scores and 30-day mortality for a cohort of mainly older inpatients with CAP. METHODS: We retrospectively analysed data from the CAP database from the years 2005 to 2009 of a single centre in Herne, Germany. Patient characteristics, criteria values within the severity scores CURB-65, CRB-65 and CURB-age, and 30-day mortality were assessed. We compared the association between score points and score-defined risk groups and mortality. Sensitivity and specificity with corresponding 95% CIs were calculated, and receiver operating characteristic (ROC) curve analysis was performed. RESULTS: Data from 559 patients were analysed (mean age 74.1 years, 55.3% male). Mortality at day 30 was 10.9%. CURB-age included more patients in the low-risk category than CRB-65 (195 vs 89), and the patient group had a lower mortality (2.6% vs 3.4%). When compared with CURB-65, CURB-age included slightly fewer patients (195 vs 214) with lower mortality (2.6% vs 4.2%). CURB-age sorted the most patients who died within 30 days into the high-risk CAP group (CURB-age, 32; CURB-65, 28; CRB-65, 9), which had the highest mortality (CURB-age, 26.4%; CURB-65, 19.4%; CRB-65, 21.4%). Advantages of CURB-age categories were depicted through ROC curve analysis (area under the curve 0.73 (95% CI 0.67 to 0.79) for CURB-age categories, 0.67 (95% CI 0.60 to 0.74) for CURB-65 categories, and 0.59 (95% CI 0.52 to 0.66) for CRB-65 categories). CONCLUSIONS: In comparison with CRB-65 and CURB-65, risk stratification as defined by CURB-age showed the closest association with 30-day mortality in our sample. Further prospective studies are needed to assess the potential of CURB-age for better risk prediction, especially in older patients with CAP.

Instruments to identify elderly patients in the emergency department in need of geriatric care.

The number of people with functional limitations, cognitive impairment and disability with unscheduled, unintended contact to emergency departments seeking acute medical care is increasing. With this, the problem of how to identify elderly people in need for acute geriatric care has evolved. The best solution to the problem would be to perform comprehensive geriatric assessment during the initial contact; however, comprehensive geriatric assessment is considered too complex and therefore not feasible for emergency departments. Instead, screening instruments have been developed and proposed. In this narrative review, selected screening instruments are discussed. The instrument best studied in various settings and countries is the Identification of Seniors At Risk (ISAR) screening tool which contains six simple questions that are easy to administer and can be assessed even in urgent situations. In recent years, several studies have examined the validity of ISAR in different European countries. Most of these studies, including one German study and a recent systematic review, confirmed the validity of ISAR. Unfortunately, evidence is conflicting, as some studies found only weak or even no association between ISAR and negative health outcomes. Other instruments have been investigated to a lesser extent and do not indicate obvious advantages over ISAR. Despite growing evidence in the field, there are still many uncertainties. Further research is needed to solve existing inconsistencies and to assess how elderly patients screened positive for acute geriatric care needs can best be managed further.

The Ariadne principles: how to handle multimorbidity in primary care consultations.

Multimorbidity is a health issue mostly dealt with in primary care practice. As a result of their generalist and patient-centered approach, long-lasting relationships with patients, and responsibility for continuity and coordination of care, family physicians are particularly well placed to manage patients with multimorbidity. However, conflicts arising from the application of multiple disease oriented guidelines and the burden of diseases and treatments often make consultations challenging. To provide orientation in decision making in multimorbidity during primary care consultations, we developed guiding principles and named them after the Greek mythological figure Ariadne. For this purpose, we convened a two-day expert workshop accompanied by an international symposium in October 2012 in Frankfurt, Germany. Against the background of the current state of knowledge presented and discussed at the symposium, 19 experts from North America, Europe, and Australia identified the key issues of concern in the management of multimorbidity in primary care in panel and small group sessions and agreed upon making use of formal and informal consensus methods. The proposed preliminary principles were refined during a multistage feedback process and discussed using a case example. The sharing of realistic treatment goals by physicians and patients is at the core of the Ariadne principles. These result from i) a thorough interaction assessment of the patient's conditions, treatments, constitution, and context; ii) the prioritization of health problems that take into account the patient's preferences - his or her most and least desired outcomes; and iii) individualized management realizes the best options of care in diagnostics, treatment, and prevention to achieve the goals. Goal attainment is followed-up in accordance with a re-assessment in planned visits. The occurrence of new or changed conditions, such as an increase in severity, or a changed context may trigger the (re-)start of the process. Further work is needed on the implementation of the formulated principles, but they were recognized and appreciated as important by family physicians and primary care researchers.Please see related article: http://www.biomedcentral.com/1741-7015/12/222.

External validation of the CURSI criteria (confusion, urea, respiratory rate and shock index) in adults hospitalised for community-acquired pneumonia.

BACKGROUND: For patients hospitalised due to community-acquired pneumonia (CAP), mortality risk is usually estimated with prognostic scores such as CRB-65 or CURB-65. For elderly patients, a new score referred to as CURSI has been proposed which uses shock index (SI) instead of the blood pressure (B) and age (65) criteria. The new score has not been externally validated to date. METHODS: We used data from a hospital-based CAP registry to compare the ability of CURSI, CURB-65 and CRB-65 to predict mortality at day 30 after hospital admission. Patients were stratified by score points as well as score-point-based risk categories, and mortality for each group was assessed. To compare test performance, receiver-operating characteristic (ROC) curves were constructed, and the areas under the curve (AUROC) were calculated with 95% confidence intervals (CI). RESULTS: We analysed 553 inpatients (45% females, median age 78 years) hospitalised between 2005 and 2009 for CAP. Overall, mortality at day 30 was 11% (59/553). The study sample was characterised by advanced comorbidity (chronic heart failure: 22%, chronic kidney failure: 27%) and functional impairment (nursing home residency: 26%, dementia: 31%). All risk scores were significantly associated with 30-day mortality. The AUROC values with 95% CI using score points for risk prediction were as follows: 0.63 [0.56-0.71] for CRB-65, 0.68 [0.61-0.75] for CURB-65 and 0.68 [0.61-0.75] for CURSI. The CURSI-defined low-risk group (0 or 1 score point) had a higher mortality (8%) than the low-risk groups defined by CURB-65 and CRB-65 (4% and 3%, respectively). Lowering the cut-off for the CURSI-defined low-risk group (0 point only) would lower the mortality to 4%, making it comparable to the CURB-65-defined low-risk group. CONCLUSIONS: In our study, the CURSI-defined low-risk group had a higher 30-day mortality than the low-risk groups defined by CURB-65 and CRB-65. Lowering the cut-off value for the CURSI low-risk group would result in a mortality comparable to the CURB-65-defined low risk group. Even then, however, CURSI does not perform better than the established risk scores.

Falls and EQ-5D rated quality of life in community-dwelling seniors with concurrent chronic diseases: a cross-sectional study.

BACKGROUND: Although recommended for use in studies investigating falls in the elderly, the European Quality of Life Group instrument, EQ-5D, has not been widely used to assess the impact of falls on quality of life. The aim of this study was to investigate the association of single and frequent falls with EQ-5D rated quality of life in a sample of German community-dwelling seniors in primary care suffering a variety of concurrent chronic diseases and conditions. METHODS: In a cross-sectional study, a sample of community-dwelling seniors aged ≥ 72 years was interviewed by means of a standardised telephone interview. According to the number of self-reported falls within twelve months prior to interview, participants were categorised into one of three fall categories: no fall vs. one fall vs. two or more falls within twelve months. EQ-5D values as well as other characteristics were compared across the fall categories. Adjustments for a variety of concurrent chronic diseases and conditions and further variables were made by using multiple linear regression analysis, with EQ-5D being the target variable. RESULTS: In total, 1,792 participants (median age 77 years; 53% female) were analysed. The EQ-5D differed between fall categories. Participants reporting no fall had a mean EQ-5D score of 81.1 (standard deviation [s.d.]: 15.4, median: 78.3), while participants reporting one fall (n = 265; 14.8%) and participants with two or more falls (n = 117; 6.5%) had mean total scores of 77.0 (s.d.: 15.8, median: 78.3; mean difference to participants without a fall: -4.1, p < 0.05) and 72.1 (s.d.: 17.6, median: 72.5; mean difference: -9.0, p < 0.05), respectively. The mean difference between participants with one fall and participants with two or more falls was -4.9 (p < 0.05). Under adjustment for a variety of chronic diseases and conditions, the mean decrease in the total EQ-5D score was about -1.0 score point for one fall and about -2.5 points for two or more falls within twelve months. In quantity, this decrease is comparable to other chronic diseases adjusted for. Among the variables with the greatest negative association with EQ-5D ratings in multivariate analysis were depression and fear of falling. CONCLUSIONS: The findings suggest that falls are negatively associated with EQ-5D rated quality of life independent of a variety of chronic diseases and conditions.

Predictive validity of the identification of seniors at risk screening tool in a German emergency department setting.

BACKGROUND: The identification of patients at high risk for adverse outcomes [death, unplanned readmission to emergency department (ED)/hospital, functional decline] plays an important role in emergency medicine. The Identification of Seniors at Risk (ISAR) instrument is one of the most commonly used and best-validated screening tools. As to the authors' knowledge so far there are no data on any screening tool for the identification of older patients at risk for a negative outcome in Germany. OBJECTIVES: To evaluate the validity of the ISAR screening tool in a German ED. DESIGN: This was a prospective single-center observational cohort study in an ED of an urban university-affiliated hospital. Participants were 520 patients aged ≥75 years consecutively admitted to the ED. MEASUREMENTS: The German version of the ISAR screening tool was administered directly after triage of the patients. Follow-up telephone interviews to assess outcome variables were conducted 28 and 180 days after the index visit in the ED. The primary end point was death from any cause or hospitalization or recurrent ED visit or change of residency into a long-term care facility on day 28 after the index ED visit. RESULTS: The mean age ± SD was 82.8 ± 5.0 years. According to ISAR, 425 patients (81.7%) scored ≥2 points, and 315 patients (60.5%) scored ≥3 points. The combined primary end point was observed in 250 of 520 patients (48.1%) on day 28 and in 260 patients (50.0%) on day 180. Using a continuous ISAR score the area under the curve on day 28 was 0.621 (95% confidence interval, CI 0.573-0.669) and 0.661 (95% CI 0.615-0.708) on day 180, respectively. CONCLUSION: The German version of the ISAR screening tool acceptably identified elderly patients in the ED with an increased risk of a negative outcome. Using the cutoff ≥3 points instead of ≥2 points yielded better overall results.

Anticholinergic burden measures, symptoms, and fall-associated risk in older adults with polypharmacy: Development and validation of a prognostic model.

BACKGROUND: Anticholinergic burden has been associated with adverse outcomes such as falls. To date, no gold standard measure has been identified to assess anticholinergic burden, and no conclusion has been drawn on which of the different measure algorithms best predicts falls in older patients from general practice. This study compared the ability of five measures of anticholinergic burden to predict falls. To account for patients' individual susceptibility to medications, the added predictive value of typical anticholinergic symptoms was further quantified in this context. METHODS AND FINDINGS: To predict falls, models were developed and validated based on logistic regression models created using data from two German cluster-randomized controlled trials. The outcome was defined as "≥ 1 fall" vs. "no fall" within a 6-month follow-up period. Data from the RIME study (n = 1,197) were used in model development, and from PRIMUM (n = 502) for external validation. The models were developed step-wise in order to quantify the predictive ability of anticholinergic burden measures, and anticholinergic symptoms. In the development set, 1,015 patients had complete data and 188 (18.5%) experienced ≥ 1 fall within the 6-month follow-up period. The overall predictive value of the five anticholinergic measures was limited, with neither the employed anticholinergic variable (binary / count / burden), nor dose-dependent or dose-independent measures differing significantly in their ability to predict falls. The highest c-statistic was obtained using the German Anticholinergic Burden Score (0.73), whereby the optimism-corrected c-statistic was 0.71 after interval validation using bootstrapping and 0.63 in the external validation. Previous falls and dizziness / vertigo had the strongest prognostic value in all models. CONCLUSIONS: The ability of anticholinergic burden measures to predict falls does not appear to differ significantly, and the added value they contribute to risk classification in fall-prediction models is limited. Previous falls and dizziness / vertigo contributed most to model performance.

Health economic perspective on a community-based intervention for older people at risk of care dependency - results of a prospective quasi-experimental study.

This prospective, quasi-experimental study aims to compare healthcare resource utilization (HCRU) and costs of a multi-component care approach for older people in a community setting (intervention group (IG)) with usual care in a matched control group (CG) during a 21-month observation period. The reablement-oriented intervention included a geriatric assessment, a case and network management and digital supporting tools. Regression models were applied to determine intervention effects regarding hospitalization, total hospital length of stay (LOS), number of physician consultations, and healthcare costs using claims data. 872 subjects were included in the IG and 1,768 in the CG. The analyses showed that the intervention did not affect hospitalization (OR = 1.153; 95% CI: 0.971-1.369, p = .105). However, participating in the IG lead to a small but significant increase of physician contacts by a factor of 1.078 (Exp(ß) = 1.078; 95% CI: 1.011-1.149; p = .022). A non-significant mean difference in costs of €1,183 (95% CI: €-261.6 to €2,627.6, p = .108) per participant was identified. Further research is needed to generate robust evidence on the optimal design of care approaches for older people and the health economic implications of such interventions to improve care and resource allocation decision-making. Trial registration: The study was registered at the German Clinical Trials Register (DRKS00027866).

[Disease sequelae on function in persons 70 years and older and the acceptance of a new supporting network, the NetzWerk GesundAktiv (NWGA)]. / Funktionale Krankheitsfolgen von Menschen im Alter ab 70 Jahren und die Akzeptanz eines neuen Unterstützungs-Netzwerkes, das NetzWerk GesundAktiv (NWGA).

BACKGROUND: The growing need of nursing care as life expectancy increases is a problem. The Netzwerk AktivGesund (NWGA) tries to change this development in a positive way. In a pilot region of the city of Hamburg, persons 70 years and older were invited by their health insurance companies to participate in the NWGA supportive network. Results of the acceptance analysis are described here. METHODS: In order to focus on persons at risk of need for help functional competence was assessed by using the LUCAS functional ability index (selfreport questionnaire). In an explorative way, participants, refusers, persons interested (excluded due to high functional competence), and non-responders were compared in a retrospective observational study. Sociodemographic and routine data were used as ICD diagnoses from hospitalisations, number of contacts to physicians and level of need of nursing care during the 12 months before recruitment. RESULTS: There were 962 participants (7.4 %), 948 refusers (7.2 %), 2437 persons with interest (18.6 %) and 8753 non-responders (66.8 %) from the 13 100 persons contacted by mail. The sociodemographic factors differed between these groups. ICDs typical of older patients and ICD codes of functional impairment from the 5422 hospital stays showed different frequencies. Persons with interest had nearly no need of nursing care and the lowest level of morbidity. CONCLUSIONS: The results show that impairments of motoric and cognitive functions, in particular, and sociodemographic factors have impact on the acceptance of the NWGA. The recruitment for participation should be improved using approaches that are differentiated, respectively. Awareness of functional impairment as disease sequelae and pacemaker of need of nursing care, in general, might facilitate health promotion and prevention in older persons. An interest in preventative activities was remarkably frequent among the persons 70 years and older.
