The demographics of home care pharmacists and the frequency and perceived importance of home care pharmacy tasks were studied. Two questionnaires were mailed in August 1994 to each of 1420 sites that provide home care pharmacy services. Home care pharmacists were asked to provide information on themselves and their companies and to rate 47 home care pharmacy tasks (administrative, clinical, distributive, and miscellaneous) on how often they are performed as part of the job and how essential they are for successful job performance. Of the 2840 surveys mailed to the 1420 sites, questionnaires for 87 sites were not deliverable, leaving an adjusted gross sample of 1333 sites. A total of 393 usable questionnaires were received from 326 sites (net site response rate 24.5%). Respondents tended to be male, have a B.S. degree only, and have more than six years' home care experience. The most commonly identified type of employer was an independent company. Some 34% of respondents said their company had only 1 site; another 33% stated more than 50 sites. Forty-three percent of locations had 2 pharmacist full-time equivalents. Distributive tasks had the highest frequency scores; clinical tasks were performed second most frequently. Distributive and clinical tasks also received high importance scores. The data suggests that, despite other demands on their time, home care pharmacists give considerable attention to tasks consistent with pharmaceutical care. A survey of home care pharmacists provided baseline information on demographics and the frequency and perceived importance of specific tasks.
