Between study visits (at Weeks 1, 2, 3, 5, 6, 7, 9, 10, and 11), you will receive a phone call once a week. The phone system is "automated," and it asks you the same MDASI-HF questions as the questionnaire that you completed at the clinic. For all of the questions, you will enter a number on your phone's keypad to answer the questions. Completing the phone questionnaire should take about 10-15 minutes each time. At the end of the phone questionnaire, the system will direct you in scheduling your next call.
