Masimo Rad-G® is helping doctors identify pediatric pneumonia in a large field trial in India

New Delhi (BUSINESS WIRE) – Nov 30, 2021-Masimo (NASDAQ: MASI) today announced the results of an in Clinical Medicine Insights: Pediatricspublished study in which Dr. Harish Kumar and colleagues at IPE Global in New Delhi, India shared their experience with the Masimo Rad-G ® Pulse Oximeter to help healthcare providers identify and treat pneumonia in more than 4,500 children under five with symptoms of acute respiratory infection ( ARI). Rad-G is a rugged, portable, hand-held Masimo SET ® Measure-through Motion and Low Perfusion ™ pulse oximeter and non-invasive breathing rate monitor made from the Pleth (RRp ®). The researchers found that Rad-G was “very acceptable to health workers” and aided in the “timely classification and treatment” of pneumonia – and helped themachieve correct case management in more than 91% of ARI cases and reduce the unnecessary use of antibiotics.

Study author Dr. Kumar commented, “Our decision to choose Rad-G as our pulse oximeter of choice to aid HWCs in screening pneumonia has proven to be a good one. The device is easy to use and maintain even in resource-poor environments, and because of its ability to accurately and reliably measure SpO 2 and RR, it has the potential to be used in the detection and treatment of pneumonia by healthcare professionals, including those who may not be doctors , to change. We hope that our study will help convince many more Indian states of the value of integrating the use of Rad-G and its technological advantages into their treatment practices and support nationwide efforts to Successfully diagnose and treat as many cases of pediatric pneumonia as possible. “

As the authors note, pneumonia – one of the leading causes of ARI in children – accounts for 15% of child deaths worldwide, with India accounting for 20% of those deaths. In resource-poor healthcare facilities where access to diagnostic tools is limited, health workers often rely on manual respiratory rate counts to make decisions about ARI management. In this study, researchers rated oxygen saturation (SpO 2) and respiratory rate (in line with WHO guidelines for effective pneumonia management) measured by Rad-G. Given the often “inadequate skills” of frontline health workers in resource-poor and rural settings – for example, it has been foundthat the majority of workers in Indian health and wellness centers (HWCs) “had no knowledge of how to properly assess a child with a cough or difficulty breathing” – the authors hoped that Rad-G could help health workers diagnose pneumonia more easily, Prove to be “good usability” and ultimately contribute to India’s goal of greatly reducing child mortality from pneumonia. Prove to be “good usability” and ultimately contribute to India’s goal of greatly reducing child mortality from pneumonia. Prove to be “good usability” and ultimately contribute to India’s goal of greatly reducing child mortality from pneumonia.

The researchers selected Rad-G from among other available pulse oximeters for a variety of reasons, most notably the integration of the respiratory rate from the Pleth (RRp) and the accurate and reliable SpO2. Before proceeding with this larger study, a first study in a only performed tertiary care hospital to assess the accuracy of RRp on Rad-G. This study found a 97% association between Rad-G RRp and the pediatrician-measured RR with high sensitivity, specificity and accuracy. 2 The authors also pointed out Rad-G’s long-life, rechargeable battery, LCD display, and the fact that a single sensor could be used on all children under five.According to the initial study, Rad-G was introduced in 19 HWCs in seven states in India and its implementation and usefulness (including ease of use and durability) were tracked over a 15 month period from June 2019 to August 2020. During this period, a total of 4,846 children between the ages of 2 and 60 months with symptoms of ARI visited the facilities. To help assess the cases, providers received shortened training in the Indian Integrated Management of Newborn and Childhood Diseases (IMNCI) program, which treats children with ARI as severe pneumonia (SpO 2 <90% or the presence of “general signs of danger”) , Pneumonia (rapid breathing or chest retraction), or neither (neither of the above).

Of the 4,846 children, 0.1% were diagnosed with severe pneumonia and 23% with pneumonia. When reviewing the cases on a monthly basis, the researchers found that 91.4% of all cases were treated correctly. In addition, 12 children with severe pneumonia who were referred would have been missed without the use of Rad-G pulse oximetry.

The researchers concluded, “The implementation of the pulse oximeter has been found to fit well with primary health care. The ruggedness and ease of use of the device is perhaps its greatest observed benefit, which has led some of the states to budget for PO [pulse oximetry] to grow in all districts. Government should consider rigorous assessment in full-scale facilities. The implementation tentatively shows that a systematic approach to diagnosing pneumonia is likely to improve case management. “

The authors also noted, “Given the importance of hypoxemia and rapid breathing as signs of serious illness, an ideal pulse oximeter is a device that functions as a point-of-care device, is durable, affordable, easy to maintain, and has fast, reliable non-invasive SpO 2 measurements. A device that measures respiratory rate should also be considered for wider use because it is difficult for medical personnel to measure respiratory rate manually. Improving case management of pneumonia at the primary care level by expanding ARI diagnostic aids while increasing IMNCI coverage, the strengthening of the referral channels and the improvement of the quality of care in referral facilities will contribute significantly to the SDG goal [Sustainable Development Goal] of reducing mortality under 5 years. “
