Chronic pain sufferers are being interviewed in a supply closet and asked to wait years for treatment at one Vancouver clinic, a CTV News investigation has revealed.
Anesthesiologist Jill Osborn works in the acute and chronic pain division at St. Paul’s Hospital, one of few non-private providers of multidisciplinary assessment, consultation and treatment in the Lower Mainland.
But Osborn said a lack of funding has led to wait lists of between one and three years at the facility, depending on the severity of a patient’s condition.
“They are suffering and it’s not acceptable for them to be waiting that long for treatment,” she said, adding that extended periods of pain can affect a person’s emotions, social life, family and career.
“By the time a person’s had chronic pain for six years they are very depressed and have many social issues as well.”
Adding insult to injury, when patients arrive at St. Paul’s hospital for an assessment they have the option of being interviewed within earshot of other patients or, if they prefer privacy, being sat down at a wood table in a narrow supply closet.
“If nurses need something from the closet, they will knock on the door and the interview will be interrupted,” Osborn said. “They will go in and get what they need and they’ll leave and then we’ll start the interview again.”
“My concern is that we are not providing the right message to the patient – that they’re important to us – when they’re interviewed in a closet.”
Osborn said the hospital’s in-patient psychiatrists and rehabilitation medicine specialists also use the closet for interviews.
The problem for chronic pain patients extends far beyond the South Coast as well, as resources are even scarcer in B.C.’s Interior.
Eighty-three-year-old Sture Kallman recently drove eight hours to access a specialist at St. Paul’s after spending years on a waiting list.
“Two to three years seems like 10 to 15 years,” Kallman said. “It would have been nice if I would have been able to get in sooner… and maybe things would be better for me today.”
Different studies have pegged the number of Canadians suffering from pain disorder at anywhere from 10 to 44 per cent of the population, but B.C. doctors say their funding is falling far behind patients’ needs and there aren't enough specialists trained in the area of chronic pain.
Health Minister Margaret MacDiarmid acknowledged the “extremely difficult” wait time for pain patients and said the province is working on a solution.
“There have been some additional financial resources put in for the doctors who practice in this area… and some of that may be able to go to this,” MacDiarmid said.
She also said the planned redevelopment of St. Paul’s Hospital could result in shorter wait times and, potentially, a larger space that would eliminate the need for closet-space consultation.
“The end of that development is years away, but it will get started, and as the site is redeveloped there will be some moving around as services,” she said.
The minister could not say with certainty that chronic pain patients would be moved to a better facility, or when the move might take place.
MacDiarmid added that while the physical space at St. Paul’s may be lacking, “the standard of care that’s being provided is fantastic.”

Pain
is a hard thing to measure, and also quite mysterious: Two people may
experience very similar injuries and similar levels of initial pain, but
where one may recover the other may go on to experience a crippling
chronic condition.
Why does pain persist for some but not others?
Scientists at the Northwestern University Feinberg School of Medicine took an interesting look at this. Their work, just published in the journal Nature Neuroscience,
tracked brain activity in 40 people with new back injuries and found a
pattern of activity that could predict -- with 85% accuracy -- which
patients were destined to develop chronic pain and which weren't.
Study subjects, all of whom had an episode of back pain
that had lasted four to 16 weeks, were tracked for one year. Images of
their brains were taken at the study start and then several more times
over the year. After one year, they were divided into two groups: ones
whose pain appeared to be resolving and those whose pain was persisting.
At
the start, there wasn't much difference between the levels of pain
reported by the two groups. However, the persistent-pain group did
differ from the recovering group in terms of their emotional feelings
about the pain.
And when senior author neuroscientist A. Vania
Apakarian and colleagues looked at the brain patterns in these two
groups, they found differences that had been there right from the start.
Two parts of the brain -- the nucleus accumbens and the medial
prefrontal cortex -- were key in the pattern. The more connected these
two regions were, the more likely a person in the study was to develop
chronic pain later on, the authors found.
The nucleus accumbens
"trains the whole rest of the brain as to values, judgments and
motivations," Apakarian said in a phone interview. And the medial
prefrontal cortex includes regions known to be involved in both acute
and chronic pain.
The scientists speculate that strong connections
between the nucleus accumbens and the medial prefrontal cortex might
somehow teach the brain to develop chronic pain -- and that this process
deserves more attention from researchers trying to develop better pain
therapies. They note that most of the focus on chronic pain to date has
been on damage in the peripheral nervous system and spinal cord that
might set up nerves to send “I’m hurting” signals long past the time
when an injury actually happened.
The scientists also found -- as
had others before them -- that people with chronic pain lost more gray
matter in their brains over time compared with healthy controls and the
people whose pain was getting better.
There are two ways in which the new findings could be useful, Apakarian says.
One
is with prediction: "If you could tell a patient, 'Don't worry, your
pain will go away in a few weeks,' that would be fantastic," he said.
And the people whose brain scans portend chronic problems?
Doctors could focus therapeutic efforts on them -- although, Apakarian said, treatments are not yet very good.
Which
brings us to his second hope -- that the findings in his lab could help
improve matters. Identifying the crucial brain regions offers clues to
neurotransmitters that might be involved in setting up chronic pain, and
therefore ways to potentially interfere with targeted medications.
Apakarian has received money from the National Institutes of Health to investigate potential drug therapies, first in animal studies.
