Developing a video expert panel as a reference standard to evaluate respiratory rate counters in paediatric pneumonia diagnosis

05 May 2022
Clinical Research Results Abstract Research Idea Abstract Outline of the research question: How can a video expert panel (VEP) be developed as a reference standard to evaluate respiratory rate (RR) counters in paediatric pneumonia diagnosis?Background: Fast breathing (FB) pneumonia is identified by observing child’s chest and counting RR. Manual RR counting is challenging for health workers often resulting in misdiagnosis of pneumonia. Novel RR counters (e.g., ChARM, Rad-G, uPM60) can count RR and detect FB automatically. However, absence of an appropriate reference standard to evaluate these devices is a challenge. If good quality videos could be captured and RR interpretation from these videos could be systematically conducted, this could be an ideal reference standard. This study is designed to develop a VEP as a reference standard to evaluate novel RR counters.Possible methodology: We will record the child’s chest movements, and these videos will be reviewed by VEP. A mechanism to interpret RR from the recorded videos will be established. This study will be carried out in Bangladesh. Eligible children will be 0-2 months old presenting with any illness and 2-59 months old presenting with suspected pneumonia (cough and/or breathing difficulty). We will take videos of child’s chest movements both with and without using ChARM. We will develop a standard operating procedure of capturing good quality videos, will make a set of reference videos and will train and standardise the VEP members using these reference videos. We will record videos from a selected hospital in Dhaka. We will also conduct a cross-sectional study among children presenting at first level health facilities in rural Sylhet for evaluation of the performance of ChARM. Questions to discuss: What will be procedure of videography? How will the VEP be trained and standardized? What will be the mechanism of interpretation of RR? What could be the possible challenges in this study? Service Development & Evaluation Abstract Declaration of Interest All authors have declared no competing interest.
