Construction and application of three-dimensional evaluation model of single bed efficiency in hospital / 中华医院管理杂志

ABSTRACT

Objective:To build a three-dimensional evaluation model of single bed efficiency in an obstetrics and gynecology hospital and provide reference for bed management in hospital.Methods:The sample ward and key indicators were determined through interviews. A two-level database was built according to patients′ data from hospital information system. K-means cluster analysis was used to get the beds classified by annual average vacancy(x), annual average turnover(y) and annual average case-mix index per capita(z). The authors built the three-dimensional bed efficiency model with x, y, z as boundaries and analyzed the bed efficiency by comparing the within group average point A k( x k, y k, z k) with the overall average point A0( x, y, z). Whereafter the bed efficiency of each medical work team was analyzed. Results:Thirty-six beds were classified into 4 categories according to utilization efficiency. 50% of the beds(18 beds) were well used, 28%(10 beds) had room for improvement, and 19%(7 beds) may have resource waste. Significant differences existed in bed efficiency among medical work teams.Conclusions:The model in our study can realize in-depth exploration by evaluating bed efficiency from two aspects of the whole ward and each medical work team. This model, which is mainly applicable to the situation where beds are under the charge of fixed medical work groups or doctors, can be adjusted and extended to meet different strategic needs of hospitals.
