Pre-MET nurse & Charge Nurses will have follow up of Patients based on their MEWS Chart criteria and will track in Pre-MET Forms and inform the MET Team before activation of MET Calls. Data were collected and analyzed. It reveals that, Overall pre MET is 73.68% and MET is 26.32% in 3rd floor A & B Wards. Overall pre MET is 80.77% and MET is 19.23% in General Ward. Overall pre MET is 76.47% and MET is 23.53% in 1st Floor ward, General ward & 3rd Floor ward – 2024. Overall Mean percentage level of Pre MET & MET in wards is pre MET is 76.06% and MET is 23.94% in 1st Floor ward, General ward & 3rd Floor ward – 2024.
