For many Americans, a routine surgical procedure represents their first exposure to opioid pain medications. Although most patients discontinue opioid use as they recover, a substantial proportion of individuals who were previously opioid-naïve continue using these medications well beyond the expected recovery period. This phenomenon, known as New Persistent Opioid Use (NPOU), has emerged as an important contributor to long-term opioid-related harm.
A recent systematic review and meta-analysis led by researchers at Penn Nursing and published in Pain Medicine sought to identify patient-level risk factors that predict the transition from short-term postoperative opioid use to persistent use. The study synthesized data from 27 high-quality studies, providing a comprehensive assessment of factors associated with NPOU. The analysis revealed four key predictors that significantly increased the likelihood of long-term opioid use following surgery: Medicaid enrollment, preoperative benzodiazepine use, mood disorders, and anxiety.
Among these factors, Medicaid enrollment and preoperative benzodiazepine use were the strongest predictors, each associated with a 77% increase in the odds of developing NPOU. Patients with a history of mood disorders, such as depression, experienced a 24% higher risk, while those with pre-existing anxiety disorders had a 17% increased likelihood of persistent opioid use. These findings highlight the critical role of social determinants of health and mental health conditions in shaping postoperative outcomes.
NPOU is defined as continued opioid use beyond three months after surgery and has been linked to increased morbidity, higher mortality, and long-term complications. Importantly, the study demonstrates that being opioid-naïve before surgery does not guarantee protection against prolonged use. By identifying high-risk patients prior to surgery, clinicians can implement targeted monitoring, alternative pain-management strategies, and supportive interventions. Integrating these evidence-based insights into preoperative screening practices may help reduce unintended opioid dependence and improve long-term patient outcomes.
