Analysis of cost-benefit of Scientific Instruments in the Preclinical Laboratory of the Faculty of Medicine, Thammasat University.

Abstract

           The purpose of this research was to analyze the utilization and cost-benefit of scientific instruments in the Preclinical Laboratory of the Faculty of Medicine at Thammasat University during the fiscal years 2018-2022. Data were collected from the operational logbooks of various laboratories, including Anatomy, Physiology, Biochemistry, and Microbiology, to assess the use of scientific instruments in teaching. Statistical analysis of frequencies, averages, and percentages was performed using Excel.

           The results revealed that out of 314 scientific instruments, 206 (69.36%). The Microbiology Laboratory had the highest utilization rate at 81.43%, indicating the effective management of laboratory equipment to meet users' specific needs. Additionally, 93.69% of the scientific instruments were found to be older than the recommended 5-year age limit for scientific and medical equipment. The microscope was identified as the most cost-effective instrument, with a lifespan of 15 years and extensive use across multiple Health Center laboratories. The budget for purchasing and maintenance of microscopes was calculated at an average expenditure rate of 69.03 baht per student. The findings of this study provide insights into the usage and costs associated with scientific instruments in each laboratory. This information will be valuable for the Faculty of Medicine in managing its budget for purchasing new scientific instruments, replacing outdated ones, and maintaining existing equipment.
