Study summary

Assessing non-inferiority of a newly developed electronic stethoscope NoaScope in comparison with the conventional 3M Littmann stethoscope

Read the detailed description

The enrolled population will include adults with a history of heart and lung complications. The enhanced sound quality of the electronic stethoscope and its non-inferiority to the traditional/conventional 3M Littmann stethoscope will be assessed through auscultation examination of every patient by a health professional (consultant, medical resident, and house officer) with both the electronic stethoscope and 3M Littmann/traditional/conventional stethoscope

What researchers measure

Primary outcomes

  1. Correctly identified abnormal heart and lung sounds by doctors using two stethoscopes: NoaScope and 3M™️ Littmann®️ Classic III.

    Each patient will receive two auscultation examinations: one with NoaScope and another with 3M™️ Littmann®️ Classic III. The investigators will determine the clinical feasibility and non-inferiority of NoaScope to the FDA-approved 3M™️ Littmann®️ Classic III from auscultation findings (heart and lungs) by doctors (holding varied levels of clinical expertise). Doctors will examine each patient using two stethoscopes: NoaScope and 3M™️ Littmann®️ Classic III. The investigators will also measure inter and intra observer agreement by the Kappa index with the help of a questionnaire. Kappa values \< 0.8 means weak to moderate level of agreement and Kappa values between 0.8 - 1.0 would mean strong level of agreement.

    Time frame: 1 month

  2. The measurement of sound quality in a clinical setting by means of an MOS scale on a questionnaire.

    The investigators will measure sound quality on a mean opinion score scale with values ranging form 1 (bad) to 5 (excellent).

    Time frame: 1 month

Secondary outcomes

  1. Difference in performance between subgroups of doctors based on clinical experience.

    This will be estimated as a proportion difference of correctly identified heart and lung sounds for each doctor subgroup.

    Time frame: 1 month
