ABSTRAK

Jabatan Kecemasan Pusat Perubatan Universiti Kebangsaan Malaysia (PPUKM) menerima kedatangan pesakit yang ramai pada setiap hari menyebabkan jabatan ini kerap berdepan dengan masalah kesesakan. Justeru, objektif kajian ini adalah mengenal pasti model pengoptimuman terbaik untuk menambahbaik sumber bagi meningkatkan tahap kecekapan Jabatan Kecemasan PPUKM dan menyelesaikan masalah kesesakan jabatan. Kaedah simulasi digunakan bagi membina model jabatan kecemasan dengan pemboleh ubah yang digunakan dalam pemodelan simulasi ini adalah dikhususkan berdasarkan zon atau ruang rawatan. Alternatif penambahbaikan yang dicadangkan ini mengandungi konfigurasi bilangan sumber jabatan yang baru. Enam model gabungan yang digunakan terdiri daripada Model CCR dan Set Rujukan, Model BCC dan Set Rujukan, Model CCR dan Kecekapan-Super, Model BCC dan Kecekapan-Super, Model Bi-Objektif MCDEA-CCR dan Kecekapan Silang dan Model Bi-Objektif MCDEA-BCC dan Kecekapan Silang. Model Bi-Objektif MCDEA-BCC merupakan lanjutan kepada Model Bi-Objektif MCDEA-CCR daripada kajian terdahulu. Keputusan kajian menunjukkan Model Bi-Objektif MCDEA-BCC yang dibina telah memberikan bilangan alternatif penambahbaikan cekap yang paling kecil berbanding model-model gabungan lain. Melalui model gabungan ini juga satu alternatif penambahbaikan yang optimum yang telah dicadangkan dapat mengurangkan masa menunggu pesakit di Zon Hijau sebanyak 51% manakala peratusan penggunaan tenaga kerja sumber berjaya ditambahbaik agar lebih munasabah. Alternatif ini memerlukan susun atur kembali kedudukan sumber tanpa melakukan perubahan yang besar ke atas sistem asal.

ABSTRACT

The Emergency Department of Universiti Kebangsaan Medical Centre (PPUKM) receives a high number of patients daily resulted in numerous problems particularly overcrowding. Therefore, this study is designed to identify the best optimization model that improve resources in order to improve the efficiency level of the PPUKM Emergency Department and solve the overcrowding problem. Simulation technique is used to build a simulation model of the emergency department where the variables used in the model are specified by triage zones or treatment areas. The proposed alternative improvements contains a new configuration of department resources. Six combined models used are the CCR Model and Reference Set, BCC Model and Reference Set, CCR Model and Super-Efficiency, BCC Model and Super-Efficiency, Bi-Objective MCDEA-CCR Model and Cross-Efficiency and Bi-Objective MCDEA-BCC Model and Cross Efficiency. Bi-Objective MCDEA-BCC Model is a continuation of Bi-Objective MCDEA-CCR Model from previous studies. The results showed that the Bi-Objective MCDEA-BCC Model has derived the least number of efficient alternative improvements compared to other combined models. It also suggested an optimum alternative that can reduce the patient waiting time in the Green Zone by 51% while the percentage of resource utilisation has been improved to be more reasonable. This alternative needs redesigning the department’s resources without making major changes to the original system.
