Abstract 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.

Abstract Background Rheumatic heart disease affects 33 million people in low and middle income countries and is the leading cause of cardiovascular death among children and young adults. Penicillin prophylaxis has been shown to improve valvular function among patients with clinically silent or mild disease. Efforts to expand echocardiographic screening are focusing on simplified protocols, non-physician ultrasonographers, and portable ultrasound devices, including handheld ultrasound. Recent advances support the use of single-view screening protocols. With the increasing availability and low cost of handheld devices, prospective studies are needed to evaluate their performance in these settings. Methods We conducted a cross-sectional study among 19 at-risk school-children participating in a rheumatic heart disease screening program in Ethiopia comparing a handheld ultrasound device (Phillips Lumify) to a fully-equipped portable ultrasound machine (Sonosite M-Turbo). Results Agreement between devices was similar for expert and non-expert review (84%). However, when reviewed by a non-expert the Lumify identified fewer screen-positive cases (p-value 0.083). We also compared non-expert to expert interpretation by device and found a significant difference in interpretation for the Lumify (p-value 0.025). There was a trend towards shorter jet length by color Doppler in the handheld ultrasound device for both expert and non-expert review. Conclusions Our study highlights the importance of using caution when applying proposed single-view criteria as the sensitivity and specificity may be affected by the device.
