Objective To develop the management information system of recognition,prevention and control of incontinence-associated dermatitis(IAD) and to explore its application effects in the prevention and nursing management of clinical incontinence dermatitis. Methods The management group of IAD was established,and the management information system of IAD identification and prevention and control was constructed. The man-machine interaction technology was used to develop four modules,including evaluation,grading,decision-making and nursing documents,so as to realize the functions of evaluation and early warning,intelligent interpretation of grading judgment, decision-making guidance and record preservation. It was officially put into clinical application in July 2019. The time-consuming,timely rate,accuracy rate,update rate and incidence rate of IAD were compared before and after the application of the system. Results After the application of the information system,the time to implement risk assessment of patients by nurses was shortened from(2.88±0.38) min to(1.44±0.45) min;the timely rate of risk assessment of IAD increased from 52.5% to 82.5%;the accuracy rate of assessment increased from 57.5% to 85.0%,and the update rate of risk assessment of IAD increased from 17.5% to 77.5%(P<0.05). The incidence of IAD decreased from 16.0% to 11.8%(P>0.05). Conclusion The management information system of recognition,prevention and control of IAD can provide accurate and objective decision-making bases for nurses,shorten the time for risk assessment of incontinence-associated dermatitis,improve the timely rate and accuracy of assessment,the dynamic updating rate of risk assessment and grading assessment,and help to improve the quality of skin care for incontinence-associated dermatitis.
