While UDT is one marker of risk, there are numerous other indicators suggesting that a patient is being harmed, or is at risk of harm, from opioid medications…
While urine drug testing is one of the most objective markers of risk, there are other factors that need to be considered when weighing the risks and benefits. Chapter 9 covers how to act in the clinical context based on the overall balance, with a focus on UDT results. This section will focus on how other observations may contribute to a patient’s risk assessment.
It is important to note that not all aberrant behaviours indicate opioid misuse. Some patients may demonstrate aberrant behaviours such as drug hoarding or escalating doses without permission due to other reasons such as inadequate pain control. If pain is adequately treated, these behaviours may subside. It is important to consider alternative explanations for these behaviours within the patient’s context.1
Your patient has been escalating their dose twice now and you have other soft concerns for harm. You don’t think you have enough to justify tapering and stopping at this point, but you are worried and want to put an end to this pattern of dose escalation. What options do you have?
The real concern here seems to be the pattern of dose escalation. This could be from inadequately treated pain, or alternatively from opioid abuse/misuse. One thing we have found helpful in these particular scenarios is to use the Brief Pain Inventory as a means of measuring the patient’s pain and functional impairment (if dose is escalating then typically both scores will be high). If you escalate the dose and then 2 months later the patient comes back wanting another increase, you may apply the BPI again - if the score is the same or worse then naturally it looks like opioids aren’t helping. Most of us at the MFHT don’t use the BPI otherwise, but once an early habit of dose escalation has been started it’s helpful to have this as a means of pointing that out- by the patient’s own reports - opioids don’t seem to be helping and therefore further escalations are not justified. If your clinical Gestalt dictates that a further dose increase is reasonable, then certainly consider moving the person up the risk ladder as these dose escalations are soft concerns for harm and likely tilt your risk/benefit balance.
- Be aware of drug-related aberrant behaviours but keep in mind that not all behaviours are indicating drug misuse/abuse and consider alternative explanations within the patients current context.

Once red ﬂag behaviours have been identified, the next step is having a discussion with your patient. For guidance on those difficult discussions see the next appendix, VI: Diﬃcult Discussions with Patients..
