Over the years those of us doing palliative care in Edmonton
have worked very hard to improve our assessment and management
of palliative care patients. Those of us who have the opportunity
to visit other palliative care programs around the world as
invited speakers or visitors, often return with a renewed
enthusiasm and appreciation for what we have accomplished.
Recently a hospice program in the USA invited me, to give
presentations both at two acute care hospitals in the area,
as well as to staff of this hospice organization. I was asked
to speak on the use of "Rehydration and Dehydration in
Palliative Care", as well as on "Pain Assessment:
Beyond the Basics". The main points I made in these presentations
are a well-known routine part of our clinical management in
Edmonton. We have learned how essential it is to make a multidimensional
assessment of pain that incorporates the psychosocial and
spiritual dimensions of suffering in planning a comprehensive
approach to patient management. While in many other areas
palliative care educators are still struggling with the basic
message of appropriate opioid prescribing, we have learned
the lesson of over reliance on pharmacological management
alone and the extremely unpleasant side-effects that can be
visited on patients by an overly simplistic management approach.
In addition we have understood that ignoring the fact that
decreasing oral intake will inevitably result in deterioration
in renal function and potential accumulation of medications,
will expose the patient to potentially very unpleasant side-effects.
While the benefits of parenteral hydration in terminally ill
patients may still be somewhat controversial for some practitioners,
the need to at least decrease medications that will be accumulating,
is generally well understood by the palliative care community
in Edmonton.
My physician hosts in invited me to join them on a ward round
of their in-patient hospice facility. At that point in my
visit they had all had the opportunity to hear my presentations.
We encountered the following clinical situation: -
A man in his 70s with lung cancer and bone metastases had
been admitted to the hospice a few days previously. As a result
of persistent pain and difficulty taking oral medication he
had switched to a continuous subcutaneous infusion of morphine,
which was running at 20 mg per hour. He had a large attentive
family, of whom two to three were always present at the bedside.
Over the previous 24 hours the patient had required increasing
use of prn morphine, and had received nine prn does during
this time. I was asked to express my opinion on the most effective
approach to this apparent pain crisis. I inquired as to the
location of pain as described by the patient, information
regarding the cognition or evidence of delirium such as hallucinations,
the presence of myoclonus, oral intake and possibility of
dehydration and renal impairment. The attending physicians
indicated that the patient was unable to localize his pain,
which was "all over" because of his bone metastases.
They thought his cognition was reasonably good, and that they
assumed he was likely dehydrated as his oral intake was minimal
but they never measure urine output or considered laboratory
investigations. A subsequent visit with the patient and history
obtained from the family at the bedside was very revealing.
The family indicated that the patient had been complaining
of increasing hallucinations over the previous week, and they
had also noted increasing myoclonus during this time. They
also indicated that his cognition had decreased to the point
that he barely recognized them, and they described agitated
behavior associated with some moaning which they interpreted
as increasing pain. The clinical examination revealed a minimally
responsive patient who was intermittently restless, and could
certainly not provide any useful information. Further discussion
with the family outside the room suggested unresolved psychosocial
issues involving the patient and his family. The patient's
family expressed severe distress with regard to the apparent
discomfort of their relative. Prior to entering the patient's
room, the attending physicians had intended to increase the
morphine dose further in response to the increasing prn use.
My questions, the family's answers, and my previous presentations
(I would like to think!) resulted in ready agreement to a
different approach. The morphine was discontinued and replaced
with hydromorphone with a 50% reduction in dose. The family
was also provided with an explanation of this approach, as
well as the need to differentiate as best as possible pain
from agitated delirium.
It was apparent that the approach of the staff in this hospice
organization to increasing opioid use was almost always to
continue to increase the opioid without a careful reassessment
of underlying causes. Any resulting toxicity would then be
treated with increasing antipsychotics and benzodiazepines.
Many of us will have seen this practice approach in many other
settings that we have visited. In Edmonton we have worked
hard to educate both ourselves as well as our colleagues,
for whom palliative care is a smaller part of their practice,
on the value to patients and families of a more sophisticated
assessment and management approach. We now often take for
granted the wide acceptance of the need to consider opioid
changes and the possible consequences of renal impairment
that is well known and incorporated into practice patterns
in Edmonton. Certainly we need to avoid complacency and continue
our educational efforts and work hard to maintain and improve
our practice standards. However an appreciation for what we
have achieved and a sense of pride in our Edmonton Palliative
Care Program is I believe, well deserved.
