Research On Evaluation Model Of Use Efficiency With Medical Equipment In Field Medical Post

The field medical post is a kind of mobile health service organization,which is temporarily set up by the army in the operation or other tasks and take part in early treatment and part of the specialist treatment.It is cataloging preliminary by military hospital,also known as field medical team if the scale of field medical post is smaller.The field medical post is the core force of mobile health service unit,the medical equipment is the material basis for mobile health service unit to complete the peacetime/wartime health service support tasks,It directly affects the ability of health service support which whether it can play a real effect.Therefore,It is important to evaluate the use efficiency of medical equipment for the overall evaluation of health service support capability of the field medical post.Objective:Through the investigation to understand the actual situation of the field medical post drilling with actual arms and using of medical equipment.To establish the evaluation model of medical equipment use efficiency,and analyze the use efficiency of the model,To provide reference for the overall evaluation capability of health service support of the field medical post.At the same time,Find out the key factors that affect the efficiency,To provide the theoretical basis for improving the core competence of the health service unit.Methods:To combine with actual use of medical equipment in field medical post,And according the use characteristics of medical equipment to classification,It can be divided into three types:request type,occupation type and consumption type.Then,To establish the evaluation model of requesting medical equipment based on queuing theory and to analysis,To establish the evaluation model of occupying medical equipment based on linear programming and to analysis.Results:To establish use efficiency evaluation model of two types of medical equipment and to analysis it.First,the use of requesting medical equipment is regarded as a queuing process,and to establish two types models of M/M/1/?/?/FCFS and M/M/c/?/?/FCFS,and to calculate the service intensity,idle probability,queue length,waiting queue length,average residence time and average waiting time of the models.Then,to discuss the relationship between the number of service stations,service time,service intensity and the queue length and average residence time.Second,the occupying medical equipment is divided into hardware,work efficiency and loss of three subsystems,to establish the evaluation model based on linear programming.Then,to calculate and examine the model,After examination,It is proved that the model is effective and stable.Conclusion:Based on the analysis and discussion of the two types models,the Conclusions are as follows:First,for the use efficiency of requesting medical equipment,The average queue length and average residence time of a single service station queuing system model are related to service intensity and service time of the requesting medical equipment,It is a proportional relation;Normally,the service intensity of p under 0.8 is appropriate;And reduce service time of the requesting medical equipment can effectively improve system efficiency,The use efficiency of the service system can be significantly improved by the multi service stations than the single service station,But the idle probability of the service station is also greatly improved;When the number of service stations exceeds three,The average queue length and average residence time of the service system have little change,The results show that when the time of the sick and the wounded arrives at the service station and the requesting medical equipment service time is constant,A large increase in the number of equipment can not improve the use efficiency of the system;When the multi service stations service and Under the condition of constant service time,the single queue is superior to multi queues.Second,The use efficiency of occupying medical equipment is directly proportional to the working efficiency,And It is inversely proportional to the hardware index and loss index.The loss index has a great impact on the use efficiency of occupying medical equipment,If we want to improve the use efficiency of occupying medical equipment,It is necessary to improve the working efficiency,reduce the equipment failure rate or reduce the maintenance time.Only increase the number of equipment and can't improve the use efficiency of occupying medical equipment.Third,The two types models can be used to evaluate the use efficiency of medical equipment used in different field medical posts,Also can be used for medical equipment configuration decisions in field medical post.And according to the evaluation of medical equipment use efficiency in field medical post,May be find out the problems or weaknesses in training of the field medical post.Then,according the problems or weaknesses to guide base training of the field medical post.
