3. Assessment of accuracy and sensitivity of the device in our cohort of SMA children.
The audio files recorded by carers with the Tytocare digital stethoscope resulted clear when listened to remotely. The overall quality value assigned by the remote team was “very good” (5/5 points). The vesicular murmur was detectable and rated as “very clear” in 20 (87%) children out of 23 (%) and 3/23 (13%) was “slightly disturbed” due to background noise (same as digital stethoscope friction, TV, voices). The remote team did not rate as “highly disturbed” none of the recordings.
All our patients had normal respiratory findings and these were concordant between the “bed-side” multidisciplinary teamconventional auscultation and the remote assessment in all cases.
