"Many patients attending a Chest Clinic need to do so only once. For others their condition merits regular review. Most of these people need to come to the clinic because they need chest x-rays, blood tests or breathing tests. However some patients return for review of their condition without needing any specialist investigations. We are keen to assess what proportion of our patients would be suitable for telephone consultations rather than face to face consultations and to see what advantages there might be for both patients and doctors. We are therefore interested to assess the use of telephone consultation where suitable and would like to know if you would be willing to try telephone consultation for your next appointment. In the case of telephone consultation you would be offered a day, date and time at which you would be phoned. Your consultant, would then ring you him or herself within half an hour of the appointed time {and procedurally it has been agreed by the trial participants that if, for any reason, during the trial period they are delayed with the previous patient they will excuse themselves to telephone the following patient to say that they have been delayed and they will ring them back within 15 minutes, for example} and with your clinical notes in front of them he or she would enquire in the usual way regarding how you feel, ask about your symptoms and give advice regarding any concerns you may have or advise regarding changes in treatment. You would subsequently receive a copy of the letter summarising the telephone consultation when it was sent to your general practitioner. If the telephone consultation suggested that you needed to be seen in the clinic you would be offered an appointment within two weeks of the telephone call."
