Palliative Care for End-stage Renal Disease Patients - Taiwan Experience      [ 下載 PDF ]

By Dr. Tsai, Hung-bin

In December 2016, I was invited to attend the Korean Society for Hospice and Palliative Care (KSHPC) winter conference in Seoul, Korea, and shared about Taiwan’s policy, research and experience of renal diseases’ supportive care. In January 2016, the Korean government passed the Hospice Palliative Care Law and started implementing 2017. The hospice palliative care originally for advanced cancer patients only is now extended to non-advanced cancer patients, starting with heart failure and HIV patients. As for hospice and palliative care for the end-stage renal disease patients, it is still in its pioneering stage.


In order to ensure the right of the terminally-ill patients to die well, National Health Insurance (NHI) in Taiwan has expanded the coverage for palliative care from only cancer and motor neuron disease to include other illnesses such as dementia, other brain alteration, heart failure, chronic obstructive pulmonary disease, lung diseases, chronic renal disease, liver cirrhosis, and acute renal failure.

The purpose of my visit this time is to share about the renal supportive care consensus in Taiwan with the Korean participants. Many expressed their curiosity on how Taiwanese doctors communicate with patients and families regarding the removal of life-sustaining treatment, and why and how a nephrologist works with the palliative team. For example, the dialysis treatment in Taiwan is known for its quality, so why not choose dialysis treatment instead of renal supportive care?

From the standpoint of a nephrologist, if dialysis treatment is the best option, it is without doubt that I provide dialysis treatment of the best quality until the end stage even though the course of disease might be unstable. However, from a palliative doctor’s point of view, if a renal disease patient with either advanced cancer receives long term dialysis treatment—which causes vital organ failure and needs to depend on respiratory and 24 hour care in bed—or with serious infection that leads to inevitable death; two specialist physicians can evaluate if the patient has reached the end of life stage, and whether to focus on the quality of life or the quantity.

Taiwan is still facing a difficult bottleneck at the palliative care development of non-cancer patients. Take renal supportive care, for example, where many cannot face the fact that life is about to end. Out of filial piety, children are reluctant to talk about death with their parents, and hence, have no idea how to assist their parents to end their lives with no regrets. Besides, physicians are playing an important role as well. Though nephrologists have all received complete dialysis education and training, when facing end-stage renal disease patients, it is still hard for them to tell the ugly truth. What ugly truth? The truth that once you have decided to go for dialysis treatment, there will be pros as well as cons. If unfortunate, it is very likely that one’s lifespan will be shortened; and even if everything goes smoothly, patients might still not being able to meet the ideal quality of life.

Taiwan Society of Nephrology conducted a survey to all 367 nephrologists in Taiwan last year. One of the questions asked was: “How long do you think a terminally-ill patient will last?” Of the total, 42.8% said within six months, 33% said within three months and 12.8% said within a month.

The survey shows the different perspectives we have when compared with western medics. During my visit to Cicely Saunders Center for Palliative Care, I discovered that the ideal end of life stage for them should be at least a year, so that one can have enough time to prepare for it. They highly respect patients’ needs and are totally patient-centered. On the contrary, evaluating the remaining life expectancy is not a high priority. This is a huge difference compared to the US system which often relies on many scientific instruments to predict the remaining life expectancy.

Britain also has a very thorough palliative care system. For patients over seventy with serious renal diseases seeking medical advices from National Health Service, family practitioners are first introduced to patients to provide a detailed analysis on dialysis treatment, so that patients and physicians can both decide whether dialysis is the best option or if there is any supportive care to choose from. Whereas in Taiwan, doctors rarely provide detailed information on the possible complications that come with dialysis, and patients’ wills are often neglected and dominated by family members.

Foreign research shows that dialysis treatment can only support fragile elders with multiple diseases for only a one to two year lifespan, that is, two years for those in their eighties, and one year for those in their nineties. However, even though their lifespan is extended, the life quality is generally unsatisfactory. According to statistics, there is a total of seventy-five thousand patients undergoing dialysis treatment in Taiwan, and many patients die while still on dialysis treatment. This made me wonder, is dialysis really the best option for dying well?

When Renal Supportive Care was first introduced in Taiwan, it was hindered by many difficulties and challenges. As consensus has grown during the past two years, family meetings are often being called when long-term mechanically-ventilated patients with multiple diseases require dialysis treatment. Through the Shared Decision Making (SDM) mechanism, the advantages and disadvantages of dialysis treatment will help inform both patient and family members so as to achieve a common decision. As the complete care planning progresses, it will be less misunderstood and less likely to associate dialysis treatment as a sign of abandonment and hopelessness.

Taiwan Society of Nephrology is actively promoting the ideal of SDM, that besides improving the quality of renal disease care, it is also providing a more humane option for patients to choose palliative care instead of dialysis treatment.

From the perspective of integrated care provided for end-stage renal disease patients, palliative shared care is a feasible and ideal option backed by government policy. So who is the decision maker in palliative shared care, a nephrologist or a palliative physician? At National Taiwan University Hospital, patients are first evaluated by a nephrologist and then consulted by a palliative physician when needed. Being a nephrologist and also a palliative physician myself, I receive many referral patients from other nephrologists, and I believe if palliative shared care can be introduced in SDM, patients’ rights and autonomy can be respected and prevent conflict for the families.

I can still recall the instance with an elderly woman in her nineties, who had multiple chronic diseases. Every time she received dialysis treatment, she always groaned in pain. Her blood pressure was not stable and she seemed drowsy. When the treatment was completed, she seemed even weaker than before the dialysis. In fact, she even told the medics that since she was already in her nineties and had no regrets in life, she had had enough of this treatment; however, she continued doing it for her children.

Having less or stopping dialysis treatment does not mean to refuse all medical treatments, but to resort to palliative care in order to reduce patients’ discomfort (like edema, asthma, pain, restless and seizures) by reducing the IV amount or prescribing medications. According to the suggestions of Renal Physician Association (RPA), when patients show the following symptoms, there should be consideration to terminate or discontinue dialysis treatment and provide palliative care instead:

●    Patient unable to cooperate: e.g. advanced dementia patients might pull the dialysis needle causing the failure of dialysis treatment.
●    Patient is unstable when on dialysis: e.g. severe low blood pressure.
●    Other reasons causing life to enter end-stage: e.g. advanced cancer, dementia or other diseases.
●    Patients above the age of 75 with chronic renal diseases at stage 5 with poor prognosis, and with two of the criteria below:
1.    Surprise Question: e.g. not surprise if patients passed away after 6-12 months
2.    High clinical comorbidity
3.    Obvious malfunction in daily life: e.g. Karnofsky Performance scale < 40
4.    Severe chronic malnutrition: e.g. albumin < 2.5 g/dL

Taiwan Society of Nephrology has also proposed the following preliminary reference indicator: For patients on respiratory dialysis for more than 3 months (respiratory dependence) and coma scale < 8, physicians and family members should have comprehensive communication to consider the possibility of renal supportive care or limited-care dialysis and avoid the necessary treatment.
