Telephone follow-up has been used in a variety of settings as a means of supporting patients post-discharge. This paper describes the implementation of a telephone follow-up service for cardiac surgical patients, both to monitor their progress and to bridge the gap between home and hospital. Surgical unit nurses called 1594 patients between May 1995 and October 1997. These calls were made a month after each patient had been discharged and a specially designed form was used as a guideline for the calls. This covered three main aspects of their recovery: discharge monitoring; medical problems; and convalescence problems. As well as providing a framework for the calls, the forms were then used for data collection. The forms were audited on a monthly basis with the results being communicated to the ward staff. Data gathered from the calls have highlighted areas where patient education needs to be improved, e.g. pain control, and this has been addressed. In October 1996, an evaluation of the service was performed. One hundred patients were sent a postal questionnaire asking for their views on the telephone service. Eighty-two of these were returned and the results of this survey are also contained in this report. Over time, the number of patients called each month has increased; information regarding support post-discharge has improved and the form used for calls has been revised to make the questions more appropriate.
