Modelling healthcare internal service supply chains for the analysis of medication delivery errors and amplification effects
Abstract: Purpose: Healthcare
is a universally used service that hugely affects economies and the quality of
life. The research of service supply chains has found a significant role in the
past decade. The main research goal of this paper is to model and simulate the
internal service supply chains of a healthcare system to study the effects of
different parameters on the outputs and capability measures of the processes.
The specific objectives are to analyse medication delivery errors in a
community hospital based on the results of the models and to explore the
presence of bullwhip effect in the internal service supply chains of the
hospital.
Design/methodology/approach: System dynamics which is an approach for
understanding the behaviour of complex systems, used as a methodology to model
two internal service supply chains of the hospital with a sub-model created to
simulate medication delivery errors in the hospital. The models are validated
using the actual data of the hospital and the results are analyzed based on
experimental design techniques.
Findings: It is observed that the bullwhip effect may not occur in a
hospital’s internal service supply chains. Furthermore the paper points out the
conditions for reducing the medication delivery error in a hospital.
Research limitations/implications: Because of the community hospital’s
data availability the type of service supply chains modelled in this paper, are
small service supply chains, representing only the tasks which are done inside
the hospital. To better observe the bullwhip effect in healthcare service
supply chains, the chains should be modelled more generally.
Originality/value: The original system dynamics modelling of the internal
service supply chains of a community hospital, with a sub-model simulating the
medication delivery error.
