D10 POWER ANALYSIS Power analyses for the primary hypotheses were conducted based on the following assumptions about sample size: 5 agencies; 4 nurse teams per agency, 5 nurses per team, and 5 patients subjects per nurse. These assumptions result in a patient sample size of 500 patients (5*4*5*5). We estimate that the number of patients who consent to research interviews will be about half of the patients who are eligible based in the agency's database data (i.e., 60% participation at baseline; 85% of baseline patients eligible for follow-up). Thus the number of patients in the agency's database that could be included in analyses using the this source of data will be at least 1,000.
