The purpose of this study is to assess the performance of Acute Physiology and Chronic Health Evaluation (APACHE) II, Simplified Acute Physiology Score (SAPS) II, Mortality Probability Model MPM II0 and MPM II24 systems in a major tertiary care hospital in Riyadh, Saudi Arabia. ⋯ In our ICU population: 1) Overall mortality prediction, estimated by standardized mortality ratio, was accurate, especially for MPM II0 and APACHE II. 2) MPM II24 has the best calibration. 3) SAPS II has the lowest calibration and discrimination. The local performance of MPM II24 in addition to its ease-to-use makes it an attractive model for mortality prediction in Saudi Arabia.

Acetaminophen toxicity, which can lead to hepatotoxicity, is a burden on our health care system and contributes significantly to intensive care unit admissions and cost of hospitalization. The aim of our study was to determine the epidemiology of various types of acetaminophen poisoning and analyze their outcome compared with their admission characteristics. ⋯ We recommend that the patients with suicidal acetaminophen overdose, without any concomitant poisoning, can safely managed on the medical floors.

The previous review in this series introduced the notion of data description and outlined some of the more common summary measures used to describe a dataset. However, a dataset is typically only of interest for the information it provides regarding the population from which it was drawn. The present review focuses on estimation of population values from a sample.
