Patient accepted and listed with UNOS. Now in maintenance or candidacy phase
Phase 3
Admitted for transplant procedure and inpatient stay
Phase 4
Discharged and posttransplant follow-up care
Registered Nurse Pre-transplant: Phase 1
During this phase of the liver transplant process, the RN transplant coordinator is responsible for the transplant candidate from referral to selection committee presentation. The RN coordinator is an integral part in assuring appropriate records are obtained and reviewed prior to the patient’s first visit and throughout the evaluation process, as records become available. Upon review of the records, utilizing critical thinking skills and protocols, the RN coordinator determines if additional information is needed and requests as necessary. Because the RN coordinator is an expert in the inclusion and exclusion criteria for liver transplantation , he/she has the ability to determine the need for additional records. The goal for the RN coordinator prior to the patient being seen is to assure that as complete a medical record as possible is available to the physician – this saves time for the patient and provider and avoids any unnecessary duplication of tests.
Once the patient is determined as an appropriate candidate, the RN coordinator manages the transplant evaluation, similar to a project management. Upon receipt of the physician’s order for evaluation, the RN coordinator works with various departments to schedule appointments and testing. This data is reviewed and prioritized to determine immediate needs and follow-up versus long-term or ongoing needs. For example, a lab value may be abnormal and require immediate action by the coordinator, or an abnormal cardiac test may require follow-up with a cardiac catheterization, which the RN coordinator will then assure, as scheduled, follow-up on those results and report to the appropriate provider. As the evaluation process continues, the RN coordinator collects data in a systematic manner assuring inclusion of the patient and family in this process. While scrutinizing the data, the coordinator identifies patterns in the patient’s history and status providing for a comprehensive assessment of the patient.
Patient education is one of the most important functions of the pre-transplant coordinator. Education of this population is not limited to the patient only but includes the family and others of the support system. Patient education focuses on disease processes; signs and symptoms of liver disease, including those that should be reported to the transplant program; symptom management; and specific information about the transplant process – from evaluation to long-term follow-up. This education is extremely important to the patient and family. Not only does it provide vital information to the patient but allows the formation of the nurse-patient relationship. This bond is vital in transplantation since these relationships are lifelong. The transplant education piece should include an overview of the transplant program, indications and contraindications of liver transplant, the evaluation process, selection committee, candidacy determination (accept, decline, defer for listing), and expectations for remaining or being removed from the list and issues that may lead to inactivation (status 7). Risks and benefits of the surgery should be part of the education process; however, these will be reviewed in depth during the surgical evaluation (American Nurses Association and International Transplant Nurses Society 2009; North American Transplant Coordinators Association 2009b). During this period the Model for End-Stage Liver Disease (MELD) score is described. The MELD score can be confusing to patients, so special attention is taken to explain and assure a basic understanding. Logistical information such as what to do when a liver becomes available, what to bring to the hospital, and expectations for the hospital stay is outlined. While patients and their families may not remember this information in detail, this discussion can help to serve as a reminder when the time comes for the actual transplant. A broad overview of the surgical procedure is provided as are expectations for the family before, during, and immediately after the transplant procedure. Potential complications are reviewed while it is suggested that the patient discuss these in detail with the surgeon.
The designation of a primary support and additional support persons is the most important part of patient education the transplant coordinator can discuss. Based upon programmatic considerations, the transplant coordinator has an in-depth educational session with the support person(s) to assure they have an adequate understanding of their expectations during all phases of the transplant process. The RN coordinator consults with the social worker regarding any issues that may have arisen during this education session providing continuity of care during the evaluation phase.
Medication plans and complications of immunosuppression are addressed at this time as well. Again, this provides an overview in order to manage expectations posttransplant (American Nurses Association and International Transplant Nurses Society 2009; North American Transplant Coordinators Organization 2009b).
There are regulatory requirements mandated by the Centers for Medicare and Medicaid (CMS) and/or UNOS that must be addressed during the pre-transplant phase. Often, it is simpler and more efficient to address these during the educational sessions. The first requirement is the consent for evaluation. The consent for evaluation must be signed by the patient or designee and includes acknowledgement of receipt of information from the transplant team concerning:
Overview of the entire transplant process, including required tests and evaluation
The donation process and waitlist
The surgical procedure and associated risks
Recovery expectations
Psychosocial risks
Emotional and personal stress
Financial implications
Compliance with a complex medical regimen
Alternative treatments to transplant
Right of refusal for testing, the transplant itself
Information about how recipients are selected (selection criteria)
Information about organ donor risk factors
Ability to be listed at multiple transplant centers at the same time
Ability to transfer waitlist time to another transplant center
Survival outcomes for the specific transplant center and nationally
Medicare-approved transplant facility
Acknowledgement of receipt of educational materials
Health Resources and Services Administration, Organ Procurement and Transplantation Network (2014a).
Multiple listing (wait-listing for transplant at more than one center) is acceptable according to UNOS policy (United Network for Organ Sharing 2008). However, UNOS allows each center to make the determination as to whether or not they will allow it. Therefore, documentation that multiple listing has been discussed with the patient is mandatory. This is the responsibility of the RN coordinator during the pre-transplant phase. Documentation that education has taken place is required as well and is completed during the pre-transplant phase.
After the evaluation is completed, the transplant coordinator gathers and reviews the testing data. Abnormal results are reported to the provider and a plan is created. It is typically the RN coordinator who implements and follows up on this plan. The evaluation data is collated into a standard format and is reviewed at the selection committee. At this committee, all members of the transplant team speak about their interactions with the patient and family. Once a decision is made, the RN coordinator is responsible for relaying the decision to the patient and for implementing any plans or recommendations brought forward by the committee. This ongoing process can last for months; therefore, organizational and follow-up skills are imperative in this position.
The pre-transplant coordinator lists the patient with UNOS via UNet (United Network for Organ Sharing 2014). The listing is based upon blood type, body size, and MELD score. Per UNOS policy, two identical ABO results with sign-off by two team members are required. Following listing, the transplant coordinator documents in the medical record and sends correspondence to the patient and referring provider. Additionally, the UNOS patient education letter is included in the correspondence (Health Resources and Services Administration, Organ Procurement and Transplantation Network 2014b).
Registered Nurse Pre-transplant: Phase 2
Once the determination of the selection committee is complete, the waitlist management begins. This may be done by the same RN coordinator or some programs have separate waitlist managers. In either scenario, the main focus of the waitlist coordinator is to manage those patients who are awaiting transplant (American Nurses Association and International Transplant Nurses Society 2009; North American Transplant Coordinators Organization 2009b). This can be a daunting task as there are many moving parts to keep a patient activated on the waitlist. Native MELD scores, MELD exceptions, appropriate x-rays, and lab data within required time periods along with symptom and side effect management are some of the main foci of this coordinator.
MELD Score
The MELD score is a numerical scale for patients aged 12 or older, with scores ranging from 6 to 40. A score of 6 indicates a less ill patient, while a score of 40 indicates serious illness. Calculation of this score determines how urgently a patient needs a liver transplant within 3 months of the calculation. The calculation for this score uses a formula with three lab tests: total bilirubin, INR/prothrombin time, and creatinine (Health Resources and Services Administration, Organ Procurement and Transplantation Network 2014c).
Each of these lab tests are routinely measured in patients awaiting liver transplantation.
Total bilirubin measures how well the liver is excreting bile; INR is a measurement of the body’s ability to make clotting factors; creatinine is a measurement of kidney function (United Network for Organ Sharing 2008; Taber’s 2005). Of note in this situation, an elevated creatinine is an indication of poor kidney function; poor kidney function is often associated with liver disease.
For pediatric liver transplant patients, the PELD (pediatric end-stage liver disease) scoring system is in place for patients 11 years and under. While similar to MELD, the PELD score uses different lab values and other measures to determine the score – total bilirubin, INR/prothrombin time, albumin, growth failure – and is the child less than 1 year of age (United Network for Organ Sharing 2008; Health Resources and Services Administration, Organ Procurement and Transplantation Network 2014b).
Albumin measures the nutritional ability of the liver (Taber’s 2005); growth failure and age recognize the developmental needs associated with children of this age category (Health Resources and Services Administration, Organ Procurement and Transplantation Network 2014). Both MELD and PELD scores increase and decrease over time as the patient’s liver disease may improve or worsen. The goal is for the donated organs to be transplanted into those patients who are the sickest (i.e., in greatest need at the time).
The formulae are:
The MELD/PELD system was implemented in 2002. Prior to that time, liver transplant candidates were categorized into four groups according to medical urgency. Those groups included some laboratory test results as well as symptoms of liver disease. The area of concern for this system was using symptoms as a means to gauge severity of liver disease because different physicians interpret symptom severity in different ways; therefore, this was not viewed as equitable. Because of this concern, this manner of scoring candidates could not categorize patients according to severity of liver disease and therefore those who were in greatest need of the transplant. Research studies were undertaken and showed that MELD and PELD scores more accurately predict patients’ short-term risk of death if they do not receive a transplant. The MELD/PELD scores are objective and can be easily verified, providing an equitable, consistent means for determining severity of illness and need for transplant (United Network for Organ Sharing 2008).
The MELD/PELD scoring system requires that the RN transplant coordinator have exceptional organizational and follow-up skills in order to maintain accurate MELD scoring. The transplant coordinator is notified by UNOS that a listed patient’s laboratory results require updating. If the update is not completed in the allotted time, according to UNOS policy, the patient’s MELD score drops to 6 which is the lowest applicable score and basically provides few to no options for organ offers. The most recent lab results, along with the result date, are entered into UNet and the patient’s score is updated or recertified. Those patients with MELD scores of 25 or above (for ages 18 or above) must have new lab results submitted every 7 days. Additionally, the lab results can be no more than 48 h old. For MELD/ PELD scores off 25 or above (for those under 18 years of age), the lab results must be submitted every 14 days and can be no more than 72 h old. For MELD/PELD scores 19–24, the lab values must be resubmitted monthly and can be no more than 7 days old. MELD/PELD scores of 11–18 must be updated every 3 months with lab results no more than 14 days old and MELD/PELD scores of 10 or less must have lab tests resubmitted annually with lab data no more than 30 days old (Health Resources and Services Administration, Organ Procurement and Transplantation Network 2014c; Table 2).
