Paramedics often provide advance notice of patients with suspected acute myocardial infarction (AMI) so that emergency department (ED) staff can prepare for early aggressive management and expeditious thrombolysis, but the validity of this practice is unclear. Our objective was to determine the accuracy of prehospital AMI diagnosis by Paramedic Level III (ALS) attendants. ⋯ ALS paramedics can accurately identify patients likely to benefit from early aggressive AMI management. These data have implications with respect to prehospital triage of chest pain patients, "early notification" protocols and future prehospital thrombolytic strategies.

Aeromedical transport in northern areas may be associated with hypothermia. The objective of this study was to determine whether significant hypothermia (core temperature <35 masculineC) occurs in severely injured or ill intubated patients during transport by rotary wing aircraft. ⋯ During brief (<225 km) rotary wing aeromedical transport of severely injured or ill patients, significant hypothermia is uncommon and body temperature is generally well maintained with the use of simple passive measures. These findings do not justify recommendations for more aggressive core temperature monitoring during this type of aeromedical transport.

Clinical prediction rules are decision-making tools that incorporate three or more variables from the history, physical examination or simple tests. They help clinicians make diagnostic or therapeutic decisions by standardizing the collection and interpretation of clinical data. There is growing interest in the methodological standards for their development and validation. This article describes the methods used to derive the Canadian C-Spine Rule and provides a valuable reference for investigators planning to develop future clinical prediction rules.
