Persistent Pain in Older Persons:
Challenges and Solutions
Stephen J Gibson
Deputy Director, National Ageing Research Institute
Professor, Department of Medicine, University of Melbourne
Why should we be interested in pain in older age? – Prevalence and impact.
Evidence-based treatment approaches. – Multidisciplinary pain clinics.
– Providing training and best integrated treatment in residential aged care.
– Treatment approaches for pain and its impacts in persons with dementia.

Under-treatment of pain in older persons
System wide under-treatment of pain across
multiple health care settings (hospital, sub-
acute, long term care facilities). • Fewer standing orders for post-operative analgesia. (Morrison & Sui
2000, Pasero & McCaffery 1996).
• Relative under-prescription of analgesics in those with metastatic
cancer. (Bernabei et al. 1998, Cleeland et al. 1994).
• 31% with moderate pain in residential aged care receive no analgesics.
Only 13% of PRN orders given. (McClean et al. 2002, Scherder 1997).
Age bias against treatment at multidisciplinary
pain clinics. (Kee et al. 1998). • 28% of clinics never admitted a person over 70.
• 40% had indirect age barriers (i.e return to work, no comorbidity).
• Based on fictitious clinical vignette, where only age differed, older
persons were judged to be 15% less likely to be suitable for admission
and 12.5% less likely to succeed with treatment.
Staff attitudes (old don’t need as much
care, nothing can be done, takes too much
time, limited treatment options).
Patient fears and beliefs (addiction,
institutionalization, polypharmacy,
complainer, >stoicism,>pain a normal part
of ageing).

The Melbourne Pain Clinic for Older Persons
• Clinic opened in 1987 within a comprehensive
aged care service.
• Conforms to IASP definition of a multidisciplinary
pain centre.
– Multimodal approach
– Caters for all types of chronic pain
– Several treatment specialties with communal case
conferencing (Dr, Physio, Psych, Nurse, OT, Pharm)
– Provides ongoing research and training
• Currently 3 pain clinics for older persons in
Melbourne and 10 throughout the World.
Melbourne Pain Clinic: Treatment Process

EBPRAC: Implementing the Australian Pain Society Guidelines
2007 2005
Aim of the Project
The major objective was to provide a comprehensive education and training program to aged care staff within five selected residential
aged care facilities and thereby establish a sustainable implementation of best practice pain
assessment and management.
Phase 1: Pre-operational activities: Involved securing ethics approvals; convening an expert working party, finalize access to facilities including recruitment of residents and development of project scheduling.
Phase 2: Facility specific audit , prepare for implementation: This phase involved the collection/analysis of current resident pain and management practice; pain documentation and management protocols; survey of staff, residents/families. The audit data was used to guide change management procedures and education activities.
Phase 3: Education, training and implementation: An intensive education program for all staff; familiarity with APS guidelines; use of pain-assessment instruments and revised in-house pain-management procedures. Activities involved dedicated 1:1 on-the-job training. The appointment of facility “pain champions” who coordinated activities within each facility.
Phase 4: Evaluation and sustainability: The collection of post-implementation data and comparing to baseline data. The evaluation addresses outcomes for residents, staff and the facility as well as sustainability as indexed by adoption of changes into institutional policy and practice.

APS Guidelines
Achieved? Comments
12. A combination of pharmacological and non-pharmacological treatment therapies are incorporated into pain management plans for residents.
Action Required
The range of non-pharmacological treatments is not comprehensive and is very limited availability. A coordinated non-pharmacological/pharmacological treatment plan does not exist for most
residents.
13. Pharmacological treatments are based on a diagnosis and consider co-existing medical conditions.
Yes
14. Medications are tailored to type of pain and it’s severity.
Action Required
Large number of PRN orders versus ATC orders for analgesics even in those with persistent pain.
15. There is around the clock
administration of analgesic medication for residents with persistent pain.
Action Required
See above
16. Residents who fail to respond to therapy and who continue to be distressed by pain should be referred to a pain medicine specialist or a multidisciplinary pain clinic.
Action Required
Note lack of use of external pain management resources.

Staff Outcomes: Knowledge
“I think what has changed is that I’m more aware of you know, signs
[of] pain, how to identify pain … So I would tell the nurses and they
would take it from there …but it’s more knowledge and the aware bit .”
“I think a lot of PCs realise they are responsible for it and not just the
RNs and ENs. That’s definitely changed. You’re seeing more hot packs
used, more rubs used, more repositioning. So they’re (PCAs) realising
they have more of a role to play with pain management, whereas that
was missing before. Yes, they’re more well informed..” RN
• Overall, approximately 350 aged care staff were involved
in the complete training program and over 4000 hours of
instruction and training were delivered across the project.

Pain and BPSD
• Unrelieved pain has been identified as a possible cause of BPSD
• Pain is associated with higher levels of BPSD
• Those suffering from pain and dementia are consistently prescribed and administered fewer analgesics than cognitively intact residents
• Can appropriate analgesic treatment reduce pain-related BPSD?
Aim of the study: Provide an
analgesic intervention to residents to
specifically monitor changes in pain
and consequent changes in the
frequency of BPSD
• 90 participants will be split into 3
groups of 30
• Placebo
• Paracetamol
• Paracetamol + Codeine
• Double blind - research staff
and aged care staff will be
unaware of which group the
resident is in.

Summary, Future Directions & Challenges
Pain is very common in older persons but is under-treated. It can have major impacts on mood, function, cognition and Q of L.
Our studies show that appropriate treatment can greatly reduce pain and suffering in older persons.
– Integrated multidisciplinary care in the community.
– Multimodal evidence-based programs in residential care.
– Reduced pain impacts in persons with dementia.
Further research and improved training is needed.
– Must implement current knowledge into better practice.
– Need widespread education on pain in older persons.
– Development of new treatment approaches.
“Although coordination of care can always be improved at the "micro" level via local initiative and the efforts of enlightened individuals, it is only with the improvement of national systems of care that the appropriate conditions and incentives for coordination and integration of care for older people will truly exist and flourish.”

Behavioral and Psychological
Symptoms of Dementia (BPSD)
• Definition: Symptoms of disturbed perception, thought content, mood or behavior that frequently occur in patients with dementia (Finkel & Burns, 1999)
• Challenging behaviors such as screaming, wandering, aggression, agitation, and physical violence
• Seriously effects quality of life
• A major cause of distress, burden and physical trauma in staff, other residents and family members
• Psychotropic medications/antipsychotic agents (suppression of symptoms) remain the most common form of management
• Associated with increased health care costs due to greater supervision, medical practitioner call-out, staff turn-over and absenteeism
There is growing international recognition that many BPSD are not
simply part of the dementing process but rather represent behavioral
symptoms of an unmet need
• Instead of normal
verbal communication, people with moderate
–advanced dementia
express their needs via
non-typical and often challenging behavioral
symptoms
• Understanding and
targeting the cause of the behavior provides a
better alternative than
trying to suppress the
behavioral symptom via chemical or physical
restraints
Resident Outcomes
“Yes I am regularly asked about the pain by all members
of staff. Different levels of staff ask about pain.”
“It’s surprising the amount of relief I get from just the wheat pack.
The heated wheat pack is marvellous. It is a really consoling
sort of treatment.”
“I’m quite happy with it [the TENS machine]… I’ve been told it won’t
cure it but it takes away a lot of that pain… there’s nothing more
that I can do as far as I am concerned because that has more or less
fixed me up for what I wanted.”
