Medicine Drugs Circuit: Analyze Performance with Simulation Models

ABSTRACT gener Hospital mission is to insure patient safety and quality of care associated with any medical processor. Among to provide performance hospitals processors is medicine drugs circuit. Modeling and simulating is an excellent tool that allows understanding this complexity and analyzing performances. In this paper, we propose a simulation models with Colored Petri Net (CPN) of Medicine Drugs Chain. Being based on these models, we present a simulating Queue Patient model with CPN Tools which will allow some statistics measures. Keywords Hospital, medicine drugs chain, Colored Petri Net, performance. 1. INTRODUCTION The health sector in Morocco is largely depending on public demand. In fact, 85% of the medical equipment is issued by the Ministry of Public Health, the Ministry of Defense, the Security Fund (SF) and University Hospital Center (UHC). The majority of the demand coming mainly the Moroccan Ministry of Health (MMH) with a budget of nearly 10.5 billion Dirham in 2010 (against 9.8 billion Dirham’s in 2009), representing 5.5% of budget the state and 1.3% of global public expenses. However, distinguish the sector has a huge need in medical staff. MMH lists 10 933 physicians (generalists, plasticize and other specialties) and nurses, there are currently about 8.5 nurses per 10 000 inhabitants or approximately one nurse for every 1,134 inhabitants in the public area 1. In addition, Morocco has a low hospital capacity. Taking into account that private hospitals have a capacity of about 6900 beds, and the total capacity of public institutions ambulatory is about 3700 beds, and hospitals have about 26,000 beds, the supply country overall amount to almost 37 000 beds. In reporting this figure to the Moroccan population yields a ratio of about 11 beds for 10 000 inhabitants. This figure puts Morocco behind Algeria (17 beds/10 000), Tunisia (24 beds/10 000) but ahead of the Sultanate of Oman and Qatar (with 9 beds per 10 000 inhabitants) 2. In this context, the health sector is in rough conditions binding by weak financial and material resources. This requires urgent intervention in the aim to readdress these constraints and improve a service care to patients. In our case, we focus to important role of hospital supply and particularly medicine drugs chain. The medicine drugs chain is consisting of one hand of the medication chain whose goal is clinical care of patients and other hand hospital supply chain that is committed to insure the availability drugs to patients. The failing at the level of the process can generate of the undesirable effects and sometimes died of the patient. The safety of patient requires a safety clinical chain and an optimized hospital supply chain. For that, more authors resort ally to modeling and simulation as 3 , 4 5 - 6 and 7. That’s because it’s an excellent approach to provide the usual and efficient tool for the scheduling of capacities and the improvement of the efficiency. In this paper, in the same way, we propose simulation models of medicine drugs chain in Moroccan healthcare system with CPN Tools. The remainder of the paper is organized as follows. Section 2, we explain medicine drugs chain. Section 3, we propose several models of medicine drugs chain with Colored Petri Net and finally we simulate by CPN Tools plate-form.
