Abstract:
Objective:To construct a fuzzy failure mode and effects analysis(FMEA)combined multi-dimensional management mode to improve the management quality of orthopedic rehabilitation treatment equipment.Methods:14 types of failure modes in 5 aspects and 25 common situations in 7 aspects of failure causes of orthopedic rehabilitation equipment were selected as risk control objects.Fuzzy algorithm was used to evaluate the risk severity,probability of occurrence,detectability and priority value,and multi-dimensional management countermeasures were developed from the aspects of daily inspection,quality detection,maintenance and emergency management.65 units of rehabilitation treatment equipment in clinical use in the hospital were selected and divided into control group(49 units)and observation group(54 units,including 38 units in the control group and 16 newly added units)according to different management methods.The control group adopted traditional FMEA priority value management method,and the observation group adopted fuzzy FMEA combined multi-dimensional management method.The equipment failure ratio,FMEA risk assessment value and medical equipment service quality were compared between the two groups.Results:The proportion of failures due to abnormal power-on self-test,poor treatment operation quality,malfunction shutdown,unqualified quality inspection and external damage of the orthopedic rehabilitation treatment equipment in the observation group were(0.76±0.89)%,(1.72±1.35)%,(1.07±1.22)%,(2.19±0.93)%and(0.13±0.26)%,respectively,which was lower than that of control group,the difference was statistically significant(Z=2.455,Z=2.833,Z=2.236,Z=3.637,Z=2.014;P<0.05).The severity,incidence,detectability and priority values of orthopedic rehabilitation equipment risk in the observation group were(3.34±1.57)points,(2.56±0.94)points,(3.63±1.20)points and(31.29±20.80)points,respectively,which were lower than that in the control group,the difference was statistically significant(Z=2.117,Z=2.665,Z=3.149,Z=3.466;P<0.05).The results of 50 randomly selected patients,37 related medical staff and 120 random inspection showed that the patient satisfaction,medical staff recognition and random inspection standardization of the equipment in the observation group were 88%(44/50),97.30%(36/37)and 96.67%(116/120),respectively,which were higher than those in the control group,the difference was statistically significant(x2=4.882,x2=6.198,x2=8.819;P<0.05).Conclusion:Fuzzy FMEA combined with multi-dimensional management mode can reduce the failure rate of orthopedic rehabilitation equipment,control the severity,occurrence probability and detectability of equipment risks,and improve the equipment operation safety and clinical service level.
