Title: Background information

Context:
The risk factors with the greatest impact on the development of opioid-related adverse events are the duration and dose of opioid analgesic use. Beyond duration and dose of OT, many factors increase the risk of adverse outcomes and must be considered prior to initiating or continuing OT (Box 1). Given the insufficient evidence of benefit for LOT, the clinician must carefully weigh harms and benefits and educate the patient as well as his or her family or caregiver prior to proceeding with treatment. As patient values and preferences may be impacted by other clinical considerations, some patients with one or more risk factors for adverse outcomes may differ with the clinician’s assessment that the risks of OT  outweigh the potential for modest short-term benefits. Thus, it is important to consider patients’ values and concerns, address misconceptions, express empathy, and fully explain to patients with one or more risk factors that they may not benefit from, and may even be harmed by, treatment with OT. Conditions that significantly increase the risk of adverse outcomes from LOT are listed below. Patients for whom LOT is initiated should be carefully monitored, and ongoing assessment of risk should be performed with vigilance for the development of additional risk factors and adverse outcomes (see Recommendations  7-9). Consider consultation with appropriate specialty care providers if there is uncertainty about whether the benefits of OT, such as improved function (e.g., return-to-work), outweigh the risks.

Question: Why must the clinician carefully weigh harms and benefits and educate the patient as well as his or her family or caregiver prior to proceeding with treatment?

Answer: Given the insufficient evidence of benefit for LOT
