Physiological stability index (PSI) is a score proposed to evaluate the severity of different diseases in pediatric intensive care units (PICU) by giving scores to the deterioration of 34 measurable physiological variables. In order to validate PSI, it was prospectively applied to 132 patients who entered our PICU. A significant difference (p less than 0.001) was found between the average score of those patients who survived (means: 6.1) versus those who did not (means: 21); No difference was found between theoretical mortality rates obtained by logistic regression analysis and those obtained according to PSI score ranks even thought direct hemodynamic measurements like cardiac output and capillary (wedge) pulmonary pressure were not considered in this study. In conclusion, the PSI is a useful method to measure the severity of illness in pediatric intensive care and to compare results among PICU.

A mandatory lecture course in emergency medicine, consisting of 13 lectures, was given to junior medical students over 3 years at Texas Tech University Regional Academic Health Center--El Paso. The performance of the students on a 25-question pretest and posttest was compared to a statistically similar group of their classmates on geographically separate campuses of Texas Tech University School of Medicine undergoing an otherwise comparable junior year clinical curriculum. Both groups exhibited improvement in posttest scores from pretest score values; additionally, students exposed to the lecture series at Texas Tech--El Paso performed significantly higher on the posttest, compared to the other campuses. We conclude that some emergency medicine material is successfully learned by junior medical students during their required third year clerkships; however, important learning objectives within the domain of emergency medicine can be most successfully taught if a mandatory junior year lecture course in emergency medicine is also incorporated into the third year curriculum.
