The web interface provides two different forms for each patient. The first form ("general sheet") is filled-in only at first presentation and consists of 12 items regarding disease and patient history, and initial symptoms of the disease. The second type of sheet ("current visit") can be generated once for each new patient visit and includes 52 items on characteristics of the current visit, current symptoms, diagnostic tests performed, confidence of the treating physician in the diagnosis on a subjective scale, left-ventricular function, therapy, complications, and follow-up care provider after discharge. Items primarily require yes/no responses via ticking respective boxes, allowing for completing each data sheet in <5 minutes when all data are available.
