Arm Type

Experimental

No Intervention

Arm Label

Focused sonography

Usual treatment and diagnostic work-up

Arm Description

Intervention group: After the primary evaluation by a physician in the emergency department, focused sonography of the patients heart, lungs and deep veins in the legs are performed. Hereafter the further examinations and treatment are done according to hospital guidelines.

Control group: After the primary evaluation by a physician in the emergency department. Hereafter the further examinations and treatment are done according to hospital guidelines.

Outcomes

Primary Outcome Measures

The number of patients with a correct presumptive diagnosis within 4 hours after hospital admission.
The 4-hour presumptive diagnosis are compared to the final diagnosis obtained by audit after the patient has been discharged from the hospital (gold standard).

Secondary Outcome Measures

Number of patients with a correct presumptive diagnosis after primary evaluation in the control group and after sonography in the intervention group.
Sensitivity, specificity, positive predictive values, negative predictive values and diagnostic accuracy of the primary evaluation and the "4-hour" presumptive diagnosis.
Number of patients receiving appropriate, inappropriate and no specific treatment 4-hours after admission
30 day mortality
In-hospital mortality
Number of patients transferred to an intensive care unit
Number of patients given an appropriate, inappropriate and no specific treatment after primary evaluation in the control group and after sonography in the intervention group
Time to diagnostic / therapeutic thoracocentesis
Length of hospital stay
