The PSS is crucial for several reasons. Firstly, it allows for the standardization in toxicology assessments across different healthcare settings. This standardization helps in accurately comparing and compiling data on poisoning cases. Secondly, the PSS aids in resource allocation by identifying patients who require intensive care and those who can be managed with less intensive measures. Lastly, it serves as a valuable tool for research and epidemiology, providing consistent data for studies on the impact and outcomes of various toxic agents.
