1 INTRODUCTION
This protocol has been produced to reflect and amalgamate existing policies produced by the kidney and pancreas transplant centres in the UK and has been endorsed by the UK Transplant Pancreas Task Force.
2 INDICATIONS FOR SIMULTANEOUS KIDNEY PANCREAS TRANSPLANT
2.1 Simultaneous kidney pancreas transplant should be considered when the following criteria apply

- Body Mass Index greater than 30
- insulin requirements >1.5 units/kg/day

3 INDICATIONS FOR PANCREAS TRANSPLANT ALONE
3.1 Criteria

3.2 Contraindications to pancreas transplant alone

- ejection fraction below 50%
- recent myocardial infarction
- non-curable malignancy (excluding localised skin malignancy)
- active sepsis

4 INDICATIONS FOR PANCREAS AFTER KIDNEY TRANSPLANT
4.1 Criteria
Patients with stable function of previous renal allograft that meet the criteria for pancreas transplant alone.
5 THE PANCREAS AND KIDNEY TRANSPLANT ASSESSMENT
5.1 Stages of assessment
- pre-transplant assessment
- decision
- transplant list.
5.2 Pre-transplant assessment
This may be conducted as either an inpatient or outpatient. The first assessment visit must be conducted within three months of referral (although the process may take longer) unless the patient is clearly unsuitable and a Consultant Physician/Surgeon has made this decision.
5.3 Objectives of assessment procedures
- The general principle of this assessment is attention to clinical detail and also avoidance of unnecessary tests if the patient is clearly deemed unsuitable for transplantation
- To assess the patient's clinical, social and psychological suitability as a transplant recipient
- To impart factual information to the patient and his/her family concerning all aspects of transplantation
- To meet hospital staff and transplant patients as appropriate
- To provide an opportunity for the patient, and his or her family, to begin to come to terms with the prospect of transplantation, and to be informed about the procedure and its aftermath.
5.4 Assessment
This will be carried out according to each unit's protocols and practices. The following serves as a guideline and is not intended to be exhaustive or prescriptive.
The importance of the multidisciplinary involvement in the assessment of the patient and care received is paramount. The assessment may involve a whole spectrum of healthcare professionals, including Physicians, Surgeons, Radiologists, Nurses, Transplant Co-ordinators, Occupational Therapists, Dieticians, Physiotherapists, Social Workers, Psychologists (if indicated, Psychiatrists) - everyone has a key role to play.

6 FINAL DECISION
6.1 This may be carried out according to each unit's protocols and practices. However, the principles should be that the decision to place a patient on the waiting list is a multidisciplinary one. The patient and their relatives will be informed of the outcome and given the opportunity to discuss it with a representative of the transplant team.
6.2 If the patient decides to go forward for transplantation, he or she is then registered with UK Transplant and placed on the waiting list. If the patient is not deemed suitable and/or declines the option of transplantation the appropriate clinician will explain to the patient and their family the options available to them. The GP and referring clinicians should be informed of the outcome of the assessment.
7 THE WAITING LIST
7.1 The patient should receive detailed explanations, which are consistent, and key information pertaining to the waiting period for transplantation. This will be carried out according to each unit's protocols and practice.
7.2 During the waiting period the transplant unit will maintain contact with the patient and his/her family to offer support, information and guidance according to their needs. Clinical review of patients on the waiting list will be as clinically indicated.
