Logistical function and quality control in a hospital service

The characteristics of Logistical Function are studied, and are applied to controlling the quality of attention in a Medical service of a Hospital. Three variables were studied: number of annual admissions, average stay and DRG coefficients. The unit of time employed was the period of one year. Within the parameters that define this Function, the value K denotes the maximum capacity of yield of the Service in relation to the studied variable. The exponential factor b is the indicator of the ascending or descending course of the variable, which is qualified by the absolute value of the same, as much in one sense as in the other. It is essential, to be able to apply this procedure, that the human and material resources of the service under study do not vary during the entire period of observation.
