We are collecting data on heart failure patients in order to develop algorithms detect changes in the heart failure and advise the patients and physicians. Thus, we need the daily data and additional background data about your particular condition. For this purpose, we do not need your name, location, or other identifying information. We do need your age (within a year) because the probabilities of disease change with age. We have found it useful to have an emergency name and address in order to communicate analysis information if you stop interacting for some reason (eg, hospitalization), but providing that information is up to you.
We promise that we will only use your data for research purposes (analysis and algorithm development). Any use of the data in research articles will be in the aggregate or small segments without any way of identifying the source. We will also maintain the data for your use on the Web site. You will have exclusive access to your data protected by password. The data will be stored in a database accessible only by the researchers on the project.
