Abstract:
Objective:To evaluate the application effect of management mode based on constraint theory for medical equipment in equipment management of vascular surgery. Methods:Based on five-step method of constraint theory,an operation evaluation system was formulated. An information management mode of medical equipment was constructed to manage quality of medical equipment in department of vascular surgery. A total of 60 sets used medical equipment in the Department of Vascular Surgery at The Second Affiliated Hospital of Xi'an Jiaotong University from 2021 to 2022 were selected. The conventional management mode was adopted to manage these equipment between January to December 2021,while equipment was managed by using medical equipment management mode based on constraint theory (constraint theory management) of the department of vascular surgery from January to December 2022. The quality scores of operation and maintenance of equipment,average incidence rates of risk,configuration effectiveness,and timeliness of equipment management were compared between the two management modes. Results:After constraint theory management was implemented,the average scores of operation and maintenance of equipment,which included success starting-up,operation,routine maintenance and fault repair,were respectively (90.69±8.65),(89.65±4.65),(88.65±5.63),and (90.58±6.01),all of which were higher than those of conventional management mode. The differences of them between two modes were statistically significant (t=13.482,17.867,14.552,14.449,P<0.05). The average incidence rates of the risks of testing equipment,treatment,monitoring equipment and auxiliary equipment of adopting constraint theory mode management were (0.89±0.22)％,(0.84±0.23)％,(0.74±0.32)％ and (0.75±0.32％),all which were lower than those of the conventional management mode,with statistically significant differences (t=9.162,17.745,19.469,15.019,P<0.05). The average utilization rate of equipment and the average amplification of cost benefit of equipment were respectively (88.69±5.54)％ and (50.36±2.69)％ after constraint theory mode was adopted,which were significantly higher than those of conventional management mode,and the average floating rate of using equipment of constraint theory mode was (1.23±0.97)％,which was lower than that of conventional management model,the differences of them between two modes were statistically significant (t=14.174,21.564,11.811,P<0.05). The average times of emergency management for risk events included the safety of power consumption of equipment,safety of diagnosis and treatment,biological safety and radiation safety were respectively (2.36±0.64)h,(3.26±0.78)h,(4.23±1.24)h and (2.26±1.23)h after the constraint theory mode was adopted,all of which were significantly less than those of conventional management mode,and the differences of them between two modes were statistically significant (t=16.704,13.421,9.029,13.971,P<0.05). Conclusion:The application of the management mode based on the constraint theory of medical equipment in department of vascular surgery can improve the quality of operation and maintenance of equipment for safety,and shorten the emergency response time of equipment,and reduce the incidence of equipment risk,and strengthen the effect of configuration for equipment.
