To identify factors predictive of patient load at major commercial concert first-aid stations, and to characterize the spectrum of presenting injuries and illnesses at such events. ⋯ Rock concert first-aid stations evaluated 2.5 times the patient load of non-rock concerts overall, although there was substantial concert-to-concert variability. Trauma-related complaints predominate at both rock and non-rock events. These data may assist individuals and organizations planning support for such events.

Survival analysis is a group of statistical methods used to analyze data representing the time to an event of interest, e.g., the duration of survival after an out-of-hospital cardiac arrest or the length of time a patient stays in the ED. Survival analysis properly accounts for patients who are lost to follow-up and for patients who have not yet experienced the event of interest at the end of the study's observation period (censored data). This article acquaints the reader with the terminology, methodology, and limitations of survival analysis. Specific methods discussed include life tables, the Kaplan-Meier product limit estimate, the log-rank test, and the multivariate Cox proportional hazards model.

Comparative Study
Retrospective review of emergency department patients with non-variceal upper gastrointestinal hemorrhage for potential outpatient management.
To determine the number of ED patients with non-variceal upper gastrointestinal hemorrhage (NVUGIH) who could have been managed as outpatients through application of previously developed clinical guidelines. ⋯ In a non-HMO urban teaching hospital, 18 patients with NVUGIH met criteria for outpatient management in a six-month period and none developed a complication during a mean in-hospital stay of 2.1 days.

To evaluate the quality of life of survivors of in-hospital and out-of-hospital cardiac arrest, and to correlate quality of life with clinically important parameters. ⋯ Although overall survival was poor, most survivors had acceptable health-related quality of life. Therefore, concerns about poor quality of life are not a valid reason to abandon efforts to improve the health care system's response to victims of sudden cardiac arrest. Further research is necessary to identify effective strategies for improving both survival and quality of life after cardiac arrest.

To determine the incidence of clinically significant intracranial injury in the anticoagulated patient suffering minor head trauma without loss of consciousness (LOC) or acute neurologic abnormality. ⋯ The incidence of clinically significant intracranial injury is extremely low in the anticoagulated patient suffering minor blunt head trauma without LOC or acute neurologic abnormality. CT scanning may not be necessary in these patients. Larger prospective studies are needed to confirm these findings.
