“…In contrast to the above-mentioned disciplines, evidence regarding the diagnostic impact of ultrasound examinations in geriatric patients is scarce [8]. The possible role of point-of-care ultrasound (POCUS) in geriatric patients was summarized in a review by Schumacher et al [9,10] and the limited existing literature has recently been summarized [8]. Due to the documented lack of data, we proposed that geriatric POCUS should be evaluated in a prospective study as presented here [8].…”

Purpose The aim of the current study was to evaluate point of care ultrasound (POCUS) in geriatric patients by echoscopy using a handheld ultrasound device (HHUSD, VScan) at bedside in comparison to a high-end ultrasound system (HEUS) as the gold standard. Materials and Methods Prospective observational study with a total of 112 geriatric patients. The ultrasound examinations were independently performed by two experienced blinded examiners with a portable handheld device and a high-end ultrasound device. The findings were compared with respect to diagnostic findings and therapeutic implications. Results The main indications for the ultrasound examinations were dyspnea (44.6 %), fall (frailty) (24.1 %) and fever (21.4 %). The most frequently found diagnoses were cystic lesions 32.1 % (35/109), hepatic vein congestion 19.3 % (21/109) and ascites 13.6 % (15/110). HHUSD delivered 13 false-negative findings in the abdomen resulting in an “overall sensitivity” of 89.5 %. The respective “overall specificity” was 99.6 % (7 false-positive diagnoses). HHUSD (versus HEUS data) resulted in 13.6 % (17.3 %) diagnostically relevant procedures in the abdomen and 0.9 % (0.9 %) in the thorax. Without HHUSD (HEUS) 95.7 % (100 %) of important pathological findings would have been missed. Conclusion The small HHUSD tool improves clinical decision-making in immobile geriatric patients at the point of care (geriatric ward). In most cases, HHUSD allows sufficiently accurate yes/no diagnoses already at the bedside, thereby clarifying the leading symptoms for early clinical decision-making.

“…However, several external factors, such as hydration status, obesity, or recent physical activity, can affect the results ( 3 ). Therefore, muscle ultrasound is considered an available, safe, cost-efficient and quick alternative to assess skeletal muscle size ( 4 , 5 ). To date, in both elderly people and younger populations, few studies have shown good reliability and validity of muscle ultrasound compared with MRI, CT or DEXA ( 6 , 7 ).…”

Objective To evaluate the reliability and validity of a standardized ultrasound examination protocol for measuring vastus lateralis muscle size. Design Prospective cohort study. Subjects Sixteen staff members of the university hospital of Heidelberg. Methods Muscle thickness, cross-sectional area and subcutaneous adipose tissue thickness were measurxsed at 3 standardized sites on the right and left vastus lateralis muscle. Ultrasound measurements were collected by 2 independent investigators on 2 different days and compared with magnetic resonance imaging measurements. Results Intraclass correlation coefficients (ICC) for intra- and inter-rater reliability showed very good closeness of agreement for all parameters (ICC = 0.929–0.994, p < 0.001). Muscle thickness and subcutaneous adipose tissue thickness ultrasound and magnetic resonance imaging measurements revealed good to very good closeness of agreement (ICC = 0.835–0.969, p < 0.001), whereas cross-sectional area showed only average closeness of agreement (ICC = 0.727, p < 0.001). A strong predictive positive correlation for ultrasound and magnetic resonance imaging-based measurements of cross-sectional area was found (R ² = 0.793, p < 0.001). Conclusion By standardization of an examination protocol, quantitative vastus lateralis muscle ultrasound proved to be a reliable method for assessing vastus lateralis muscle size. Furthermore, this protocol is valid for measuring muscle thickness and subcutaneous adipose tissue thickness, although there seems to be a systematic underestimation of cross-sectional area depending on subcutaneous adipose tissue thickness. LAY ABSTRACT The quantification of muscle mass is crucial for diagnosis and monitoring of muscle atrophy caused by inactivity or in the context of diseases, and could also be used for monitoring the development of muscle hypertrophy during resistance training. Application of a standardized examination protocol for quantitative vastus lateralis muscle ultrasound proved to be a reliable method for assessing vastus lateralis muscle size in people with varying body weight and body composition, respectively. In this regard, it could be considered an alternative examination tool to time- and cost-consuming gold-standard magnetic resonance imaging (MRI), which is seldom readily available in clinical practice. However, compared with MRI measurements, muscle cross-sectional area measured using ultrasound seems to be systematically underestimated, depending on subcutaneous adipose tissue thickness.

“…Die meisten der teilnehmenden Ärzte (71 -85 %) hatten Interesse, die neue Methode zu erlernen, um diese auch im klinischen Alltag anzuwenden. Sie schlussfolgerten, dass GEBUS eine Technik ist, die der Praktiker zur Grundversorgung beherrschen sollte [104]. Zu beachten ist, dass diese Untersuchung in South Carolina, USA, stattfand wo die Sonografie von Hilfspersonal, nicht von Ärzten durchgeführt wird.…”
