You have been placed on our waiting list for an operation.
To help prepare for this, you are asked to attend a Pre-Operative Assessment Clinic so that your medical and social needs can be assessed before your operation. This leaflet describes what will happen during this appointment, so that you know what to expect.
The date of your surgery is provisional pending the outcome of your pre-operative assessment appointment. If you are deemed fit after your assessment then you will proceed to your planned admission date. If you do not already have this date then you will be contacted by your consultants scheduler.
The Pre-Operative Assessment Clinic will:
- Make sure that you are medically fit for your operation or procedure.
- Provide some information about your treatment and answer your questions about your admission.
- Carry out tests needed before your operation or procedure.
- Find out whether you will have special requirements during your stay, or when you leave hospital.
Following your outpatient appointment with the surgeon you will be asked to complete a health questionnaire. The nurses will undertake an initial screening including; checking your blood pressure and weight, height, and take swabs to check for MRSA which will help us plan your pre-operative appointment.
The screening helps us to determine if you need to see an anaesthetist, nurse, or healthcare coordinator.
Your Pre Assessment appointment normally takes place 6-8 weeks ahead of your provisional date for admission. However, some patients will be asked to attend pre assessment without a planned date so you are confirmed as being fit or ready for surgery.
Your initial pre assessment appointment will be made via the telephone unless you are required to see an anaesthetist. You may be asked to attend the department following this appointment if further investigations are required.
Information regarding your surgical procedure is discussed with you by the surgeon at your outpatients appointment. Staff will be happy to discuss general questions regarding your admission, length of stay, and your return home after your operation. You may want to write down questions before you come to the pre assessment clinic so that you don't forget them when you arrive.
Your initial pre assessment appointment will be made via the telephone unless you are required to see an anaesthetist. You may be asked to attend the department following this appointment if further investigations are required.

If you are under the care of a doctor, for example a heart or chest doctor, and you have copies of clinic letters detailing your care / treatment / investigations, please bring them with you to your appointment.
