Primary Outcome Measures:
  • The number of patients with a correct presumptive diagnosis within 4 hours after hospital admission. [ Time Frame: 4 hours after hospital admission ] [ Designated as safety issue: No ]
    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. [ Time Frame: Participants will be followed for the duration of the hospital stay, an expected range of up to 5 weeks ] [ Designated as safety issue: No ]
  • Sensitivity, specificity, positive predictive values, negative predictive values and diagnostic accuracy of the primary evaluation and the "4-hour" presumptive diagnosis. [ Time Frame: Participants will be followed for the duration of the hospital stay, an expected range of up to 5 weeks ] [ Designated as safety issue: No ]
  • Number of patients receiving appropriate, inappropriate and no specific treatment 4-hours after admission [ Time Frame: Participants will be followed for the duration of the hospital stay, an expected range of up to 5 weeks ] [ Designated as safety issue: No ]
  • 30 day mortality [ Time Frame: 30 days after the patient has been admitted to the hospital ] [ Designated as safety issue: No ]
  • In-hospital mortality [ Time Frame: Participants will be followed for the duration of the hospital stay, an expected range of up to 5 weeks ] [ Designated as safety issue: No ]
  • Number of patients transferred to an intensive care unit [ Time Frame: Participants will be followed for the duration of the hospital stay, an expected range of up to 5 weeks ] [ Designated as safety issue: No ]
  • 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 Frame: Participants will be followed for the duration of the hospital stay, an expected range of up to 5 weeks ] [ Designated as safety issue: No ]
  • Time to diagnostic / therapeutic thoracocentesis [ Time Frame: Participants will be followed for the duration of the hospital stay, an expected range of up to 5 weeks ] [ Designated as safety issue: No ]
  • Length of hospital stay [ Time Frame: Participants will be followed for the duration of the hospital stay, an expected range of up to 5 weeks ] [ Designated as safety issue: No ]

Study Completion Date: April 2013
Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Focused sonography
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.
Other: Focused Sonography of the heart, lungs and deep veins
The patient is randomised to either a control group where usual treatment and diagnostic work-up is performed or to an intervention group where usual treatment and diagnostic workup are supplemented by a sonographic examination of the heart, lungs and deep veins are performed within one hour after the primary evaluation. The primary evaluation is defined as the first evaluation of the patient by a physician in the Acute Medical Admission Department.
No Intervention: Usual treatment and diagnostic work-up
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.
