Research on the application of evaluation and warning system based on Shewhart control chart in medical device related pressure injury / 中国医学装备

ABSTRACT

Objective:To explore the effectiveness of the Shewhart control chart-based assessment and early warning system in prevention of medical device-related pressure injury(MDRPI).Methods:152 critically ill patients admitted to Hebei Central Hospital from January 2020 to December 2021 were selected and divided into a control group and an observation group based on different methods of assessing MDRPI risk,with 76 cases in each group.The control group adopted the Braden scale to assess the risk of MDRPI.The observation group adopted a safety early warning system based on Shewhart control charts to assess the risk of MDRPI in patients.Nursing measures were undertaken according to MDRPI risk grade in both groups.The occurrence of adverse events of MDRPI,nursing safety quality and nursing comprehensive quality were compared between the two groups.Results:The incidence rate of head,neck and face adverse events of MDRPI and the total incidence of adverse events of MDRPI of the patients in the observation group were lower than those in the control group(x2=4.802,5.758,P<0.05).The safety quality and comprehensive quality of nursing of 20 nurses in the observation group were higher than those in the control group(t=6.654,7.172,P<0.05).Conclusion:The application of assessment and early warning system based on Shewhart control chart in clinical nursing management can effectively reduce the incidence of MDRPI adverse events and improve the quality of nursing safety and comprehensive nursing.
