Patients to be included in the study would be those attending 3 respiratory clinics. The patients would be asked if they were willing to have a telephone consultation instead of their next face to face consultation and this would be explained to them.

“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.”

Demographic details and disease diagnosis would be recorded, for those not deemed suitable or for those not wishing to take part and they would continue to attend traditional face to face consultations. Those having a telephone consultation would subsequently revert to traditional consultation pending results of the trial. Frequency of planned consultation would be as per the consultant's usual practice.

Procedurally, it was agreed that for those patients agreeing to have their next consultation by telephone, the doctor would check the phone number which they wished for the investigators to use and this would be inserted in the notes at the end of the previous consultation with a large black box around it, so that it could easily be spotted at the time of the telephone consultation.

For all patients the following observations would be made: length of the telephone consultation, fail to be available when telephoned rate, and length of each face to face consultation.

For each face to face consultation the following information would be recorded: the time they left home; time of arrival at hospital, time spent waiting for consultation, expense of attendance, both travel costs but also any indirect costs such as babysitting charges and loss of earnings. For each telephone consultation the number of patients having to be reviewed within the next 2 weeks of the telephone consultation would be recorded, whether such expedited follow up was at the patient's or the doctor's behest.

After both the telephone consultation and their subsequent face to face consultation the patients would be asked to complete the post consultation patient satisfaction questionnaire, the MISS 21 questionnaire and the Howie Enablement Instrument. Patients would be posted these scales by first class post on the day of a telephone consultation and handed them for completion after a face to face consultation and on each occasion they would be given a stamped addressed envelope in which to return the completed scores.
