Low-cost, open source and point-of-care deployment of medical technologies

Key challenges that prevent transitioning medical technologies from bench-to-bedside include costs of product development, requirement of trained operators, point-of-care costs associated with administering the tests and lack of clear value propositions to patients and physicians. In a study published by us in the British Medical Journal, we evaluated significance and efficacy of advanced technology-enabled non-invasive diagnostic screening (TES) using smartphones and other point-of-care medical imaging devices vs. conventional vital sign examinations [1]. This study led to significant insights about strategies to develop technologies at MIT that are ready for deployment for effective and scalable primary care in the real world. For e.g. a) We have open-sourced the construction and the algorithm of porphyrin imaging devices and also created a cell-phone clip on that can use a mobile phone camera [2]. b) For biomarkers, such as matrix metalloproteinases-8 and -9 linked to periodontal diseases, that cannot be imaged, in collaboration with MIT Chemical Engineering, we have developed and published protocols for POC lateral flow diagnostic strip to detect it from human saliva samples [3]. c) Construction and validation of low-cost, point-of-care near-infrared imaging devices to diagnose dental caries, cracks and demineralization without use of ionizing X-rays has been published [4, 5]. d) A low-cost mask to screen for sleep apnea by physiological monitoring: respiratory activity (airflow and nasal air pressure) and sleep behavior (motion and noise) has been published [6].
