Derivation and validation of a risk adjustment model for predicting seven day mortality in emergency medical admissions: mixed prospective and retrospective cohort study.

ABSTRACT:

Objectives

To derive and validate a risk adjustment model for predicting seven day mortality in emergency medical admissions, to test the value of including physiology and blood parameters, and to explore the constancy of the risk associated with each model variable across a range of settings.

Design

Mixed prospective and retrospective cohort study.

Setting

Nine acute hospitals (n = 3 derivation, n = 9 validation) and associated ambulance services in England, Australia, and Hong Kong.

Participants

Adults with medical emergencies (n = 5644 derivation, n = 13,762 validation) who were alive and not in cardiac arrest when attended by an ambulance and either were admitted to hospital or died in the ambulance or emergency department.

Interventions
