ABSTRACT
Carrying out the optimal location selection of medical equipment in the medical community plays an important role in scientifically allocating equipment resources and improving the service capacity of medical community. Aiming at minimizing the operating cost of the location selection and configuration of the portable color Doppler ultrasound instrument in the county medical community and the shortest time spent on medical visits for residents, the authors established the total value objective function of the medical community configuration according to the value engineering method; and considered the relevant constraints such as distance, time and personnel quality, the mathematical model of optimal planning for the selection and configuration of portable color Doppler ultrasound equipment in county medical community was constructed. The empirical research results showed that based on the established constraints, after 5 000 iterations, the model output 5 relatively optimized allocation points among the 9 allocation points, and when the allocation number of each allocation point was 1, the total allocation value in the medical community reached the maximum. This study could provide a new idea and feasible method for the allocation of equipment resources of county medical community in China.
ABSTRACT
Through screening of the literature,published time,published journals,research sites,research objects,research perspectives,influencing factors and countermeasures were listed by multi angle analysis of the bibliometrics method.The results show that the research on influencing factors of patients' selection of institutions in China has reached a certain level,but there are still some deficiencies.Follow-up studies need to define the following points which include the research heat is strongly related with the policy,the research of the patient's referral influencing factors should be strengthened,the depth of research needs to be improved,and the patients is the foundation of the countermeasures.
