As medical staff also need to be protected from infection during an outbreak, the need for telemedicine is growing rapidly worldwide. However, auscultation became challenging during the COVID-19 pandemic. Although there has been a concerning decline in physicians’ auscultatory skills, auscultation will remain important in the 2020s, as cardiopulmonary diseases are important underlying or direct causes of death and morbidity, substantially impacting quality of life and health care costs. Auscultation is not only a highly cost-effective screening tool to detect abnormal clinical signs but also a useful means to build a good relationship between physician and patient. Since the French physician René Laennec invented the stethoscope in 1816, auscultation has been an essential component of clinical examination. This means that most of the real world’s essential cardiopulmonary sounds could be classified by a real-time remote auscultation system using a Bluetooth-connected electronic stethoscope. There was no cardiac sound for which the correct answer rate differed between groups.Ĭonclusions: 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. The overall test score for cardiac auscultation in the intervention group (50/60, 83.3%) was not different from that in the control group (119/140, 85.0% P=.77). 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%). The overall test score of lung auscultation in the intervention group (80/110, 72.7%) was not different from that in the control group (71/90, 78.9% P=.32).

There were no differences in age, sex, and years from graduation between the 2 groups in each part. Results: In total, 20 participants were included. The primary outcome was the test score, and the secondary outcomes were the rates of correct answers for each sound. The control group listened to the sounds directly using a traditional stethoscope.

The intervention group listened to the sounds remotely using the electronic stethoscope, a Bluetooth transmitter, and a wireless, noise-canceling, stereo headset.

#Stethoscope placement for lung sounds series

In the test sessions, participants had to classify a series of 10 lung sounds and 10 cardiac sounds, depending on the study part. 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.

All participants attended a tutorial session, in which they listened to 15 sounds on the simulator using a classic stethoscope and were told the correct classification. Each part contained a tutorial session and a test session. This study consisted of 2 parts: lung auscultation and cardiac auscultation. The only exclusion criterion was a refusal to participate.

Methods: This was an open-label, randomized controlled trial including senior residents and faculty in the department of general internal medicine of a university hospital. Objective: This study was conducted to assess the utility of real-time auscultation using a Bluetooth-connected electronic stethoscope compared to that of classical auscultation, using lung and cardiology patient simulators. However, the utility of such systems remains unknown.

A system combining an electronic stethoscope and Bluetooth connectivity is a promising option for remote auscultation in clinics and hospitals. To facilitate telemedicine, the development and improvement of remote examination systems are required.
