Abstract

A healthcare tool allows a patient to record daily parameters associated with the patient'"'"'s clinical status, for example, body weight for congestive heart failure patients. A graph may be created showing the parameters on a control chart. The parameters are statistically analyzed against a control range, and when a parameter moves out of the control range, the system automatically creates a pop-up window alerting the patient that the parameter is outside the control range, and that the patient should consider informing a healthcare professional.
