A simulation model for evaluation and design of inpatient care facilities
Pages 373 - 377
Abstract
The complexity of activities and fluctuations in workload make prospective evaluation and design of inpatient care facilities difficult. This paper describes a simulation which allows the user to select a compromise between service availability and cost by comparing alternatives for different ward sizes, ancillary capacities and admission policies. Reporting includes not only occupancy and workload figures, but also statistics on over-loads and excess occupancy. The sequence of care administered to an inpatient is modeled as a Markov chain, whose states are patient level of dependency; ward workloads and ancillary usage depend on the patient's state. Different parameters in the basic model represent the sequences of care corresponding to distinct diagnosis classes; varying patient mixes can be simulated by adjusting arrival rates in the diagnosis categories. This paper focuses on the use of the simulation in comparing admission policies.
