BACKGROUND With the coronavirus disease 2019 pandemic, the need for telemedicine is rapidly growing worldwide. The development and improvement of remote physical examination systems, especially remote auscultation, are required to facilitate telemedicine. A Bluetooth system combined with an electronic stethoscope is a promising option for remote auscultation in clinics and hospitals. In our previous work, we demonstrated that the utility of a Bluetooth-connected real-time remote auscultation system for the lung simulator is comparable to that of classical direct auscultation. However, the utility of such systems remains unknown for cardiac auscultation. OBJECTIVE This study was conducted to evaluate the utility of real-time auscultation using a Bluetooth-connected electronic stethoscope compared to that of classical auscultation using a cardiology patient simulator. METHODS This was an open-label randomized controlled trial, including senior residents and faculty members in the Department of General Internal Medicine of a university hospital. The only exclusion criterion was a refusal to participate. All participants attended a tutorial session, in which they listened to 15 heart sounds on the cardiology patient simulator using a traditional stethoscope and were told the correct classification. Thereafter, participants were randomly assigned to either the real-time remote auscultation group (intervention group) or the classical auscultation group (control group) for test sessions. In the test sessions, participants had to classify a series of ten heart sounds. The intervention group remotely listened to the heart sounds using an electronic stethoscope, a Bluetooth transmitter, and a wireless, noise-canceling, stereo headset. The control group listened to the heart sounds directly using a classic stethoscope. The primary outcome was the test score. The secondary outcomes were the rates of correct answers for each heart sound. The two groups were compared using Fisher’s exact test. RESULTS In total, 20 participants were included; six and 14 were assigned to the intervention and control groups, respectively. There was no difference in age (P=.99), sex (P=.99), or years from graduation (P=.78) between the two groups. The overall test score in the intervention group (50/60, 83.3%) was not different from that in the control group (119/140, 85.0%) (P=.77). There was no heart sound for which the correct answer rate differed between groups. CONCLUSIONS This study demonstrated that the utility of a real-time remote cardiac auscultation system using a Bluetooth-connected electronic stethoscope was comparable to that of direct auscultation using a classic stethoscope. This implies that the real world’s essential heart sounds could be classified by a real-time remote cardiac auscultation system using a Bluetooth-connected electronic stethoscope.

Abstract Objective: This study aimed to assess the utility of real-time remote auscultation using the cardiopulmonary simulators.Methods: In this open-label, randomized controlled trial, the researchers randomly assigned general internal medicine doctors to the real-time remote auscultation group (intervention group) or the classical auscultation group (control group). In the training session, participants listened to five different lung sounds and five cardiac sounds in a previously determined order with the correct classification. In the test session, participants had to classify the five lung sounds and five cardiac sounds in random order. For both sessions, the intervention group auscultated at a distance of 220 m, with an Internet-connected electronic stethoscope while watching the auscultation places on the computer screen. The control group performed direct auscultation using a classical stethoscope. The primary outcome was the total test score.Results: Twenty participants were included in the study. The total test scores of lung auscultation in the intervention (86%) and control (90%) groups were not significantly different (P = .54). The total test score of cardiac auscultation in the control group (94%) was superior to that in the intervention group (72%, P < .05). Valvular diseases were not misclassified as normal sounds in real-time remote cardiac auscultation. Discussion and Conclusions: The utility of real-time remote lung auscultation using an Internet-connected electronic stethoscope was comparable to that of classical lung auscultation. Classical cardiac auscultation was superior to real-time remote cardiac auscultation. However, real-time remote cardiac auscultation is useful for classifying valvular diseases and normal sounds.

RESULTS In total, 20 participants were included; eleven and nine were assigned to the intervention and control groups, respectively. There was no difference in age (P=.25), sex (P=.82), and years from graduation (P=.15) between the two groups. The overall test score in the intervention group (80/110, 72.7%) was not different from that in the control group (71/90, 78.9%) (P=.32). The only lung sound for which the correct answer rate differed between groups was that of pleural friction rubs (P=.03); it was lower in the intervention group (3/11, 27%) than in the control group (7/9, 78%,). CONCLUSIONS The utility of a real-time remote auscultation system using a Bluetooth-connected electronic stethoscope was comparable to that of direct auscultation using a classic stethoscope, except for classification of pleural friction rubs.

AbstractBackgroundEvaluation of efficacy, safety and feasibility of hyperthermic baths (HTB; head-out-of-water-immersion in 40°C), twice a week, compared to a physical exercise program (PEP; moderate intensity aerobic exercises) in moderate to severe depression.MethodSingle-site, open-label randomized controlled 8-week parallel-group pilot study at an university outpatient clinic as part of usual depression care. Medically stable outpatients with depressive disorder (ICD-10: F32/F33) as determined by the 17-item Hamilton Depression Rating Scale (HAM-D) score ≥18 and a score ≥2 on item 1 (Depressed Mood) were randomly assigned to receive either two sessions of HTB or PEP per week (40-45 min) provided by two trained doctoral students. An independent biometric center used computer-generated tables to allocate treatments. Primary outcome measure was the change in HAM-D total score from baseline (T0) to the 2-week time point (T1). Linear regression analyses, adjusted for baseline values, were performed to estimate intervention effects on an intention-to-treat (ITT) principle.Findings45 patients (HTB n = 22; PEP n = 23) were randomized and analyzed according to ITT (mean age = 48.4 years, SD = 11.3, mean HAM-D score = 21.7, SD = 3.2). Baseline-adjusted mean difference was 4.3 points in the HAM-D score in favor of HTB (p<0.001). This improvement was achieved after two weeks. Compliance with the intervention and follow-up was far better in the HTB group (2 vs 13 dropouts). There were no treatment-related serious adverse events. Main limitation: the number of dropouts in the PEP group (13 of 23) was far higher than in other trials investigating exercise in depression (18.1 % dropouts).ConclusionsHTB seems to be a fast-acting, safe and easy accessible method leading to clinically relevant improvement in depressive disorder after two weeks; it is also suitable for persons who have problems performing exercise training.Trial registrationGerman Clinical Trials Register (DRKS) with the registration number DRKS00011013 (registration date 2016-09-19) before onset of the study.
