Neurogeriatrics-a vision for improved care and research for geriatric patients with predominating neurological disabilities.

Geriatric medicine is a rapidly evolving field that addresses diagnostic, therapeutic and care aspects of older adults. Some disabilities and disorders affecting cognition (e.g. dementia), motor function (e.g. stroke, Parkinson's disease, neuropathies), mood (e.g. depression), behavior (e.g. delirium) and chronic pain disorders are particularly frequent in old subjects. As knowledge about these age-associated conditions and disabilities is steadily increasing, the integral implementation of neurogeriatric knowledge in geriatric medicine and specific neurogeriatric research is essential to develop the field. This article discusses how neurological know-how could be integrated in academic geriatric medicine to improve care of neurogeriatric patients, to foster neurogeriatric research and training concepts and to provide innovative care concepts for geriatric patients with predominant neurological conditions and disabilities.

Diagnostic accuracy of three different methods of temperature measurement in acutely ill geriatric patients.

OBJECTIVE: we examined the diagnostic accuracy of different methods of body temperature measurement to diagnose infection in geriatric patients presenting to the emergency department (ED). METHODS: this observational study was done in consecutive patients ≥75 years old presenting to the ED. Body temperature was determined by tympanal thermometry, temporal artery thermometry and rectal temperature measurement. Adjudicated final diagnosis of infection was done by two experts including patient history, clinical and laboratory findings as well as radiographic studies. RESULTS: a total of 427 patients were included in the data analysis (age: 82.7 ± 5.1 years). Infection was present in 105 patients (24.6%). Respiratory rate, heart rate and body temperature were significantly higher in patients with infection, blood pressure was lower (P < 0.01). Body temperature measured by tympanal and temporal artery thermometry was correlated with rectal thermometry. Body temperature was significantly higher in patients with infection compared with those without infection independent of the method of body temperature measurement (P < 0.001). The diagnostic accuracy for infection quantified by the area under curve (AUC) was comparable among rectal [AUC: 0.72 (95% CI: 0.65-0.80)] and tympanal thermometry [AUC: 0.73 (95% CI: 0.66-0.81)], but significantly lower in temporal artery thermometry [AUC: 0.65 (95% CI: 0.57-0.73; P < 0.001)]. Compared with rectal measurement tympanal thermometry showed a higher bias than temporal artery thermometry (0.54 versus 0.03°C), while its limits of agreement were more narrow (-0.14 to 1.21°C versus -0.94-1.01°C). CONCLUSION: diagnostic accuracy for the identification of infection was comparable among tympanal and rectal thermometry and lower for temporal artery thermometry. Different cut-off points should be used to identify infection using tympanal (37.3°C) or rectal (37.9°C) thermometry. In general, temperature measurement is an insensitive method to identify geriatric patients with infection. Registration number clinicaltrials.com: KSMC-tempger-1.

Early detection of non-ST-elevation myocardial infarction in geriatric patients by a new high-sensitive cardiac troponin T assay.

BACKGROUND AND AIMS: The new high sensitivity cardiac Troponin T (cTnThs) assay has recently been introduced in our clinic and ensures higher sensitivity than the fourth-generation cardiac troponin T (cTnT) assay from the same manufacturer (Roche Diagnostics). We determined the diagnostic performance of the cTnThs compared with the cTnT assay in geriatric patients, especially those with non-ST elevation myocardial infarction (NSTE- MI). METHODS: We retrospectively analysed 253 patients (age 82 ± 8 years; 82 men, 172 women) with diagnoses of suspected NSTEMI admitted to our Department of Geriatric Medicine. Patients were divided into one group of 113 patients using cTnThs, and another of 140 patients using cTnT for diagnosis. Each group included patients at the same months but different years, in either cTnThs or cTnT assays. NSTEMI was diagnosed according to current guidelines. RESULTS: Baseline characteristics were similar in both groups. The proportions of patients with elevated cardiac troponin (cTn) levels significantly increased from 35% in the cTnT group to 76% in the cTnThs group (p<0.001), although no coronary cause for the elevated cTn levels was shown in about two-thirds of these patients. In patients with NSTE- MI, 58% in the cTnThs group vs 42% in the cTnT group were diagnosed within 4 hours of the onset of symptoms, whereas 42% in the cTnThs group vs 58% in the cTnT group were diagnosed more than 4 hours later (p=0.018). CONCLUSIONS: The prevalence of elevated cTn has more than doubled with the use of cTnThs. However, no coronary cause was found in two-thirds of our geriatric patients, al- though more NSTEMI patients were diagnosed earlier by cTnThs.

Oropharyngeal dysphagia in older persons - from pathophysiology to adequate intervention: a review and summary of an international expert meeting.

Oropharyngeal dysphagia (OD) is a highly prevalent and growing condition in the older population. Although OD may cause very severe complications, it is often not detected, explored, and treated. Older patients are frequently unaware of their swallowing dysfunction which is one of the reasons why the consequences of OD, ie, aspiration, dehydration, and malnutrition, are regularly not attributed to dysphagia. Older patients are particularly vulnerable to dysphagia because multiple age-related changes increase the risk of dysphagia. Physicians in charge of older patients should be aware that malnutrition, dehydration, and pneumonia are frequently caused by (unrecognized) dysphagia. The diagnosis is particularly difficult in the case of silent aspiration. In addition to numerous screening tools, videofluoroscopy was the traditional gold standard of diagnosing OD. Recently, the fiberoptic endoscopic evaluation of swallowing is increasingly utilized because it has several advantages. Besides making a diagnosis, fiberoptic endoscopic evaluation of swallowing is applied to evaluate the effectiveness of therapeutic maneuvers and texture modification of food and liquids. In addition to swallowing training and nutritional interventions, newer rehabilitation approaches of stimulation techniques are showing promise and may significantly impact future treatment strategies.

Do clinical guidelines improve management of sepsis in critically ill elderly patients? A before-and-after study of the implementation of a sepsis protocol.

AIM: Guidelines for the management of sepsis have been published but not validated for elderly patients, though a prompt work-up and initiation of appropriate therapy are crucial. This study assesses the impact of a sepsis protocol on timelines for therapy and mortality in standardized management. METHODS: Consecutive patients aged 70 years and older who were diagnosed with sepsis and admitted during the observation periods were included in this before-and-after study at a medical intensive care unit (ICU). Age, sex, and process-of-care variables including timely administration of antibiotics, obtaining blood cultures before the start of antibiotics, documenting central venous pressure, evaluation of central venous blood oxygen saturation, fluid resuscitation, and patient outcome were recorded. RESULTS: A total of 122 patients were included. Sepsis was diagnosed in 22.9 % of patients prior to the introduction of the protocol and 57.4 % after introduction. Volume therapy was conducted in 63.9 % of the patients (11.5 % preprotocol). Blood culture samples were taken prior to the administration of antibiotics in 67.2 % of patients (4.9 % preprotocol), and antibiotics were applied early in 72.1 % of patients (32.8 % preprotocol). Lactate was set in 77.0 % of patients (11.5 % preprotocol). A central venous catheter was inserted in 88.5 % of patients (68.9 % preprotocol), and the target central venous pressure was achieved in 64.3 % of patients (47.2 % preprotocol). ICU mortality was reduced by 5.2 % and hospital mortality by 6.4 %. CONCLUSIONS: The use of standardized order sets for the management of sepsis in elderly patients should be strongly recommended for better performance in treatment. Compliance with the protocol was associated with reduced length of stay, reduced mortality, and improved initial appropriate therapy.
