Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
To evaluate the role of B-type natriuretic peptide (BNP) in the management of patients presenting to the emergency department with the presenting symptom of shortness of breath (SOB). Patients randomised to the study group will have BNP levels tested. In the test group with a positive BNP result doctors will be encouraged to use a standardised approach to the optimum treatment of CCF. Blood is taken for BNP levels upon patient arrival and results will be available within one hour. The study duration is 18 months.

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Random number generation. Whether a patient was randomised to the study group or the control group is not concealed from the study participants or the treating physicians.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Excel program was used to generate random numbers. There was no restrictions. Excel was further used on the random numbers to randomly allocate them to the study or control groups.
