The document discusses an early warning system called Lifelight that uses smartphone cameras to predict health deterioration without any wearables or contact. It analyzes faces for 30 seconds to track National Early Warning Scores, which can alert if someone is at high risk of death within 24 hours. This allows for early intervention and prevention across care settings. A prototype has been developed and is undergoing clinical validation trials to calibrate it against standard ICU equipment. Next steps involve further development and seeking partners to trial its integration into local health systems and pathways.
