A Study on the Expected Effects of Process Improvement for Reduction of Waiting Time at General Projection

Purpose : An increment in waiting time is one of the factors making patients inconvenient because of the overall improvement of service of medical institutions and the standard of public service. This is a critical factor in assessment by institution and customer on the service of the hospital and has been direct influence on the customer satisfaction survey. The purpose of this study is to increase the level of service satisfaction by minimize the inconvenient of patients through the improvement of process for the reduction of waiting time in general projection. Materials and Methods : The subjects were the visiting patients of this hospital. The waiting time before and after the process improvement of each projection room were measured and compared The way of improvement was determined by considering the staffs and equipments using the order of process improvement possibilities. The practice was carried out on the work and equipment separately. As a result, the data compiled on the general projection completion the number of cases before and after the process improvement of each projection room and compared and analyzed using the tool contained in 6-Sigma. Results : The improvements of waiting time derived from the improvement of both work and equipment were observed. The improvement of work efficiency was achieved by solving the problem of work overload imbalance through the improvement the effective assignment of projection room and staffs and continuous work training. The bottle neck phenomenon was released by the reduction in projection time due to operation of projection room only for whole spine or long bone, the improvement of productivity due to replacement of DR Type equipment, and the change of projection room only for IVP into general projection room The reduction of waiting time during peak time was reduced effectively. The change of waiting time were from 12min. to 11min. and from 23min. to 11min both for the chest projection and general projection, respectively. Conclusion : The most of general projection department of diagnostic radiology inspection are performed by the needs of medical treatment, therefore it is impossible to predict the amounts of work It was common, accordingly, for the patients of peal< time to wait long time due to the concentration of patients. This has negative effect on the level of customer satisfaction, therefore the reduction of waiting time is important in improving the level. It was shown that the improvement of process was most effective. It is concluded that the improvement of process leads to the productivity increment and effective management on staffs, ultimately, to the improvement of customer satisfaction.
