            Pre-hospital emergency network serves as a major gateway to the Accident and Emergency (AE) department of  hospitals which is affected by overcrowding, and majority of projects studying pre-hospital emergency care network  deal only with ambulance or fireman localisation as a means of addressing the problems confronting the Accident and Emergency (AE) department. However, this research work studied in detail the patient flow through the pre-hospital emergency care network. Taking into account not only fireman and private ambulances localisation, but also the other services performed in this network such as Emergency call service the service of the Emergency response team using Timed Coloured Petri Nets.

            In developing a Timed Coloured Petri Nets (TCPN) model for a pre-hospital emergency care network, the emergency service of the State of Osun (O’ambulance) was used as a case study. The developed pre-hospital emergency care network (TCPN) model consists of five sub modules. Arrival sub module modelled the arrival of emergency calls with different health cases. Sort call sub module modelled the call desk and how emergency calls are received by the available call desk agent (perm). Perm Decision sub-module modelled the decision of call desk agent (perm) based on the emergency cases. Rescue team (RT) Decision sub module modelled the decision and intervention of Rescue team. While the Rescue-to-hospital sub-module modelled the transportation of victims to hospital.  The developed TCPN model was simulated using CPN tools. The validation of the developed TCPN model was explored by carrying out the statistical analysis between the simulated and the observed emergency call cases under study.

            The simulation results of the developed TCPN model revealed the number of emergency cases that require immediate and urgent response as 2, 6 and 19 while those that require no immediate response as 8, 22, 64 for the first, second and third simulations respectively. Revealing that some emergency calls require no immediate response and patients do not need to be taken to the hospital. Statistically, there were no significant difference between the simulated and the observed number of emergency cases that require immediate and urgent response.


Conclusively, this research work has been able to develop a TCPN model for studying a pre-hospital emergency care network. Also, the developed Timed Coloured Petri Nets model, through its simulation, could help in predicting the number of patients that do not need to be taken to the emergency department hence, reducing overcrowding in  hospitals.

1.1                  General Overview

               The accident and emergency (AE) unit is one of the most sensitive and crucial departments in hospitals. Patients with severe conditions are admitted and treated without prior appointment and this department operate 24 hours a day, seven days a week. AE unit reason for being crucial can be accrued to the fact that it provides treatment to patients whose condition needs serious and immediate attention.  The sensitivity of the unit is as a result of the fast and important decisions that needed to be made by the medical practitioners, who are to attend to numerous patients with diverse medical conditions ranging from accidents like food poisoning, fire burn  and other emergency cases.

As a result of the nature of accident and emergency (AE) unit, it suffers from a lot of complexities, overcrowding and anomalies which must be paid attention to in order to deliver high quality care. AE unit overcrowding is due to many complex reasons that can be related to the pre-hospital emergency care network, the ED itself, or to the exit of the ED. Many studies tried to analyse this problem. Some of them deal with the improvement of the ED system (Yeh and Lin 2007). Other ones focus on the post-hospital care, especially the problem of allocation planning of hospital bed resources (Wang et al., 2007). Some other researchers are interested in studying the pre-hospital network emergency care which sorts out patient flow. In fact, a bad organization of this pre-hospital network may be an important cause of the ED overcrowding (Cotard 2002; La Cour des Comptes 2007).The majority of projects studying this network deal especially with ambulance or fireman localisation (Takeda et al. 2007). In this research work, a detailed study of the patient flow through the pre-hospital emergency care network was considered.  Taking into account not only fireman and private ambulances localisation, but also the other services performed in this network such as Emergency call service

A model of the actual processes of pre-hospital care network was developed, since modelling plays a key role in complex system development. Modelling is the use of a simple, but explicit form to represent discrete event system. Timed Coloured Petri Nets (TCPN) was chosen to simulate the developed model.

1.2    Statement of the Problem

         In hospital, problems occur due to  congestion and complexity in accident and emergency unit. A lot of anomalies such as overcrowding, long waiting time, and insufficient staffs coupled with wastage of available resources  affect the treatment of patients and the overall clinical processes of the accident and emergency department (Joumana et al., 2011).

        The previous area of research work studying pre-hospital emergency care network deal only with ambulance or fireman localisation as a means of addressing the problems confronting the Accident and Emergency (AE) department. However, this research work studied in detail the patient flow through the pre-hospital emergency care network. Taking into account not only fireman and private ambulances localisation, but also the other services performed in this network such as Emergency call service and the service of the Emergency response team. Timed Coloured petri nets (TCPN) was used to model the care flow in pre-hospital network.


1.3       Aim and Objectives

           The aim of this research work is to model and simulate a  pre-hospital emergency care network using Timed Coloured Petri Nets.

 The specific objectives are to:

i.                    develop a Timed Coloured Petri Net (TCPN) model for a pre-hospital emergency care       network using Osun State Emergency Service, Osogbo, as a case study;

ii.                  simulate the developed TCPN model using CPN tools;

iii.                validate the developed TCPN model on the basis of the simulated and the measured         emergency response rate.


1.4       Significance of the Study

 In this field of study, a concept is not studied directly but through a model of the system. By the manipulation of the representation, it is hoped that new knowledge about the modelled system can be obtained without danger, cost or inconvenience of manipulating the real system itself. Thus, the developed Timed Coloured Petri Nets model through its simulation could help in studying and improving pre hospital emergency  care service  and  hence, reduces overcrowding in Emergency department in hospitals. 


1.5       Scope of the Study

In this research work,  Osun State Emergency Service, was considered, having thirty ambulance vehicle distributed across the thirty Local Government of the State, with four ambulance vehicle stationed in strategic places  in the State Capital, Osogbo.  Timed Coloured Petri Nets was mainly used to model the  pre-hospital emergency care network with the use of CPN tools to simulate the model.  Validating the developed TCPN model on the basis of the simulated and the measured emergency response rate

1.6       Methodology

            The methods of the study employed in this research work are as follows:

i.                    Establishment of a theoretical foundation for the research through a sound literature          review.

ii.                  Identification of pre-hospital emergency care network process.

iii.                Discussion and Collection of record from pre-hospital emergency management.

iv.                Development of a model for the process.

v.                  The developed model was simulated three times using Timed Coloured Petri Nets                         tools.
