This document outlines a study to establish financial performance benchmarks for hospitals in Thailand. The study analyzed financial statements and key ratios of 821 hospitals to identify benchmarks for expenses, revenues, and metrics like EBITDA, cash ratio, average collection period, average payment period, and service cost. The benchmarks will allow hospital managers and oversight agencies to evaluate financial performance and identify issues. While the model is still being developed, establishing these benchmarks provides a baseline for financial management and planning. Further refining the methodology is recommended to account for variations within hospital types.
