Impact of eliciting treatment priorities on analgesic prescribing in older patients with high levels of polypharmacy

<p dir="ltr"><b>Background:</b><b> </b>Multimorbidity guidelines recommend tailoring care to patients' priorities. The Supporting Prescribing in Multimorbidity in Primary Care (SPPiRE) trial focused on optimizing medicines use in older adults with significant polypharmacy and tailoring prescribing and deprescribing to individual priorities. This study aimed to compare self-reported and general practitioner (GP)-recorded patient priorities and examine the impact of prioritizing pain on analgesic prescribing.</p><p dir="ltr"><b>Methods:</b><b> </b>This secondary cohort analysis of the SPPIRE trial and process evaluation assessed baseline participant-identified priorities and intervention group GP-recorded priorities during medication reviews with agreement assessed using Cohen's kappa. Analgesic prescribing patterns and daily morphine milligram equivalents changes during the study period were summarized. The impact of pain (self-reported, GP-recorded, and severe or extreme pain on the baseline EQ5D) on opioid intensification was analysed using multi-level models accounting for GP practice clustering and intervention effects.</p><p dir="ltr"><b>Results:</b><b> </b>A total of 403 patients (mean age 76.5 years) were included; 178 (44.2%) reported pain as a priority at baseline. Agreement between self-reported and GP-recorded pain was poor (kappa 0.118, P = 0.05). Most analgesic prescriptions decreased during the study, except for potent opioids, which increased in both trial arms. All three pain variables were associated with increased odds of opioid intensification at follow-up.</p><p dir="ltr"><b>Conclusion:</b><b> </b>In this older population of patients with significant polypharmacy, identifying pain as a priority was associated with an increased likelihood of opioid intensification, despite guidelines advising against their use for chronic pain. This study highlights the challenges faced by GPs treating pain in older adults with multimorbidity.</p>
