  Purpose
Acute dyspnea is a common chief complaint of patients presenting to the emergency department. Patients with acute dyspnea display a high mortality rate. In-hospital mortality is as high as 10% during hospitalization and up to 30% within 6 months of follow-up. The Triple A Initiative Study is designed to improve the coordination of care for patients with acute dyspnea alerting the Emergency Medical Service (EMS). We hypothesize that the coordination of care starting at the EMS level including point-of-care testing of the cardiac biomarker NTproBNP will support preclinical and clinical diagnostic clarification. Treatment deriving from earlier diagnostic clarification will reduce length of stay in the hospital, treatment costs and improve patient's outcome.

Condition Intervention
Dyspnea Heart Failure Device: NTproBNP measurement with point of care device "Cobash232" in the POCT group

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: A Prospective Randomized Study of Coordinated Diagnostic Pathways and Treatment Algorithms for Patients With Acute Dyspnea Including Point-of-care Testing of a Cardiac Biomarker by the Emergency Medical Service Team

Primary Outcome Measures:
  • Days alive and out of hospital within 30 days [ Time Frame: 30 days ]

Secondary Outcome Measures:
  • Cost-effectiveness analysis evaluating both costs and effects of alternative therapies (NT-proBNP vs. control group) at day 30, 90 and 180 days [ Time Frame: 60 months ]
  • Diagnostic accuracy of chest ultrasound to detect patients with acute heart failure [ Time Frame: 1 month ]
  • In-hospital length of stay during follow-up of 30 and 90 days [ Time Frame: 3 months ]
  • Improvement of symptoms (dyspnea) 24h, 48h, 72h hours after admission [ Time Frame: 1 month ]
  • Need for ICU admission during initial hospitalization [ Time Frame: 6 months ]
  • B-type natriuretic peptide level and calculated glomerular filtration rate at discharge [ Time Frame: 6 months ]
  • Patients functional status at 30, 90 and 180 days (Barthel Index) [ Time Frame: 6 months ]
  • Mortality at 30, 90 and 180 days [ Time Frame: 6 months ]
  • Total treatment costs at 30, 90 and 180 days [ Time Frame: 6 months ]
  • Days alive and out of hospital at 90 and 180 days [ Time Frame: 6 months ]

Enrollment: 67

Arms Assigned Interventions
No Intervention: default group
Patients with the randomization result "default group" receive standard diagnostics
Active Comparator: POCT group
patients with the randomization result "POCT group" receive a NTproBNP measurement with point of care device "Cobash232" in the ambulance vehicle
Device: NTproBNP measurement with point of care device "Cobash232" in the POCT group

Detailed Description:

The aim of this prospective, randomized study is to evaluate the effects of point-of-care testing of NT-proBNP in patients presenting with acute dyspnea to the Emergency Medical Service (EMS).Patients will be enrolled in the Emergency Medical Services of participating German hospitals (Klinikum Nürnberg, Klinikum Fürth, Universitätsklinikum Jena). To be enrolled in the study, each patient must meet all of the following inclusion criteria and none of the exclusion criteria.

Patients with acute dyspnea randomized to the POCT group will get a NT-proBNP-POCT measurement in the EMS. The emergency physician of the EMS will decide to apply predefined treatment strategies according to the resulting working hypothesis. Patients with acute dyspnea randomized to the standard care group will NOT get NT-proBNP measurement at the scene. The emergency physician of the ED will construct the working hypothesis following current treatment recommendations. The major focus of the study is to initiate treatment of heart failure as early as possible.
