It assigns numerical scores parameters including respiratory rate, oxygen saturation, body temperature, systolic blood pressure, heart rate, and level of consciousness. </span><br> <b><span lang="EN-MY">Methods:</span></b> A quasi-experimental design used to conduct this study in Emergency Department at Main Hospital, Assiut University, Egypt<span lang="EN-MY">, </span>purposive sample of 120 patients enrolled and randomly assigned in 1:1 ratio to a study group receiving Early Warning Score based care (n = 60) and a control group receiving routine care (n = 60) using simple coin-flip randomization. Data collected over six months (January&ndash;June 2025). Three tools used: tool I: patient assessment, tool II: Early Warning Score implementation, and tool III: patient outcomes.<br> <b>Results:</b> Patients in both groups were predominantly male (45.0% in the study group and 60.0% in the control group), with comparable mean ages (46.48 &plusmn; 8.38 vs. 45.93 &plusmn; 11.51 years). Study group experienced a substantial reduction in unplanned ICU admissions (23.3% vs. 68.3%, P < 0.<span lang="EN-MY"><span style="color:black">001</span></span><span lang="EN-MY">), </span>and significantly lower rates of emergency surgery, urinary tract infection and neurological complications (p < 0.01). However, the mean hospital stay was longer in the study group than control group (6.72 &plusmn; 2.31 vs. 4.25 &plusmn; 1.23 days; p < 0.001).<br> <b><span lang="EN-MY">Conclusions</span></b><span lang="EN-MY">: </span>although the study limited to a single acute care setting, findings suggest that structured physiological monitoring enhances early recognition of deterioration.</span></span></span></div> Acute care, Early Warning Score, Outcomes 9 9 http://jrh.gmu.ac.ir/browse.php?a_code=A-10-2857-1&slc_lang=en&sid=1 Ehlash Tag Aldin Ahmed EkhlasElkhteeb@gmail.com 1 100319475328460045800 Yes Asdiut University, Egypt Mona Aly Mona@aun.edu.eg 2 100319475328460045801 No Assiut University, Egypt Hanan Mahmoud Drhanan_abalrus@aun.edu.eg 3 100319475328460045802 No Assiut University, Egypt
