Author: David E. WeissmanThe term
Pseudoaddiction was first used in 1989 to describe an iatrogenic syndrome
resulting from poorly treated pain. The index case was a 17y/o man with
leukemia, pneumonia and chest wall pain. The patient displayed behaviors
(moaning, grimacing, increasing requests for analgesics) wrongly
interpreted by the physicians and nurses as indicators of addiction,
rather than of inadequately treated pain. Put simply, Pseudoaddiction is
something that we do to patients, through our fears and mis-understanding
of pain, pain treatment and addiction.
Diagnostic Features
Behaviors that suggest to the health care provider the possibility of
psychological dependence (addiction):
--Moaning or other physical behaviors in which the patient is trying to
demonstrate to the provider that they are in pain;
--Clock-watching or repeated requests for medication prior to the
prescribed interval;
--Pain complaints that seem "excessive" to the given pain stimulus;
--Inadequately prescribed and titrated opioid analgesics; typically the
use of an opioid of inadequate potency (e.g. 50 mg of meperidine) and/or
at an excessive dosing interval (e.g. oral morphine q6 hours prn).
Anytime there is a suggestion, because of escalating pain behaviors, that
a patient on opioids may be "addicted", Pseudoaddiction should be
ruled-out. Perform a complete pain assessment and review the recent
analgesic history:
Is this a pain syndrome that typically responds to opioids?
Is the current opioid dose, route and schedule appropriate? If so, has a
reasonable attempt at dose escalation been made?
Is there any past medical history to suggest a substance abuse disorder?
Complete a comprehensive addiction assessment if such a disorder is
suspected.
Pseudoaddiction improves with the provision of adequate analgesia,
including opioids. In contrast, addiction gets worse when analgesia,
including opioids, is administered.
Management
If you believe the current problem is Pseudoaddiction, there are two key
management steps:
I. Establish trust-a primary issue in most cases is the loss of trust
between the patient and the health care providers. The physician and
nursing staff should meet to discuss how they will restore a trusting
therapeutic relationship; outside assistance from a pain or palliative
care service may be helpful. Plan to meet with the patient and openly
discuss the events leading up to the current problem; engage the patient
in the decision process about the current and future use of analgesics.
II. Prescribe opioids at pharmacologically appropriate doses and
schedules; aggressively dose escalate until analgesia is achieved or
toxicities develop (see FF # 18, 20, 36). Frequently re-evaluate progress
in pain management and ask for consultation assistance.
