Abstract:
Objective:To construct a risk assessment model based on probabilistic hesitant fuzzy set(PHFS)for pressure-related injuries in medical equipment,and analyze its application value in control and management for risk of pressure-related injuries in medical equipment in the department of emergency.Methods:The frequency of events caused by pressure-related injuries of equipment was counted as statistical method.Combined with the risk assessment factors of pressure-related injuries,the technique for order preference by similarity to ideal solution(TOPSIS)based on PHFS was used to evaluate the risk level of pressure-related injuries of equipment,and formulate corresponding measures for risk management of pressure-related injuries.A total of 120 used medical equipment at the Department of Emergency of the First Affiliated Hospital of Xi'an Jiaotong University from January 2024 to December 2024 were selected.Using the random number table method,60 equipment were managed with the conventional risk management mode for pressure-related injuries(conventional management mode),and the other 60 equipment were managed with risk assessment model based on PHFS(model management mode)for pressure-related injuries in medical equipment.The incidence of pressure-related injuries of equipment,scores of operational quality of equipment,incidence of pressure-related injuries at different staging were compared between two kinds of management modes.A self-made questionnaire was used to investigate the satisfactions of emergency doctors,nurses,patients,and medical engineers in the department of equipment,who used and managed equipment.Results:The scores of operational standardization,pressure controllability,and diagnostic comfort in the model management mode were respectively(93.36±4.56),(90.54±3.69)and(93.65±4.69)points,which were significantly higher than those in the conventional management mode,while the score of material sensitivity was(30.23±3.26)points,which was significantly lower than that in the conventional management mode(t=15.941,11.896,11.511,17.200,P<0.05).The incidences of occurring pressure-related injuries in the referred logs of diagnosis and treatment of respiratory equipment,monitoring equipment,infusion equipment,and oxygen supply equipment in the model management mode were significantly lower than those in the conventional management mode(x2=9.924,9.493,9.796,8.075,P<0.05).The incidences of stage 1,2,3,and 4 of pressure-related injuries of equipment in the model management mode were significantly lower than those in the conventional management mode(x2=7.209,6.985,8.048,7.473,P<0.05).The satisfactions of emergency doctors,nurses,patients,and medical engineers in the department of equipment for the clinical use of equipment in the model management mode were significantly higher than those in the conventional management mode(t=12.499,13.200,14.410,9.226,P<0.05).Conclusion:The risk assessment model based on PHFS for pressure-related injury of medical equipment can reduce the incidences of pressure-related injuries of medical equipment in the department of emergency,and improve the safety of using medical equipment,and enhance the service quality of clinical equipment,and increase the satisfaction for equipment in clinical applications.
