Evaluating an Intelligent Module for Pressure Injury Nursing Management

1.Number of newly admitted patients assessed within 2 h: The system automatically pulls timestamps from the Nursing Management System-start time = patient's arrival timestamp; end time = nurse's submission timestamp of the Braden assessment. Records with an interval ≤ 2 h are counted as "timely." 2.Total newly admitted patients in the period: The system extracts the total number of patients who completed admission procedures. 3.Formula:Braden Risk Assessment Timeliness Rate = (number of newly admitted patients assessed within 2 h ÷ total newly admitted patients in the period) × 100%

1.The required assessments based on the patient's Braden score: ≥19 (no risk): once on admission and once on discharge 15-18 (low risk): once per week 13-14 (moderate risk): twice per week (re-assessed on Tuesday and Friday) 10-12 (high risk): once per day 0-9 (very high risk): once per nursing shift (three shifts) Actual assessments: The assessments recorded in the nursing system. Missed assessments= required assessments - actual assessments 2.Formula:Braden Assessment Omission Rate =Missed assessments (required count - actual count) ÷ Required count

1.The system automatically pulls from the Nursing Management Information System all in-hospital and community-acquired pressure injury (PI) reports submitted every month. The wound-care specialists then identify-per NPUAP/EPUAP staging criteria-those records whose initial stage was judged "incorrect." 2.Total Reports: The system simultaneously extracts the total number of all PI reports submitted during the same month. 3.Formula: PI staging accuracy (%) = (correctly staged cases ÷ total reported cases) × 100%.

1."Monthly incident cases": Automatically extracted each month from the Nursing Management System-counts all newly acquired pressure injuries that have been reported during the month. "Total inpatient episodes for the same period": Simultaneously extracted the total cumulative inpatient episodes for the month, including transfers and deaths; same-day readmissions are counted only once. 3.Formula: Hospital-acquired pressure injury incidence (%) = (monthly new hospital-acquired cases ÷ monthly total inpatient episodes) × 100%.

• Annual wound outcome records: The system automatically pulls the wound outcome fields (healed / improved / unchanged / deteriorated) for all discharged patients with PIs in per year. 2.Total number of PI patients: The sum of all hospital-acquired plus community-acquired pressure injury cases in the same year, denoted as N. 3.Formula: • Healing rate (%) = (number of healed cases ÷ N) × 100% Improvement rate (%) = (number of improved cases ÷ N) × 100% Unchanged rate (%) = (number of unchanged cases ÷ N) × 100% Deterioration rate (%) = (number of deteriorated cases ÷ N) × 100%
