The retrospective study by Dr. Alrawashdeh and coinvestigators focused on electronic health record data for adults admitted to 373 hospitals in the United States between 2009 and 2015, including 375,479 who had sepsis.
Over time, there was a significant increase in the prevalence of OUD among those hospitalized for sepsis, from less than 2.0% in 2009 to more than 3% in 2015, representing a significant 77.3% increase. In general, the prevalence of sepsis was significantly higher among hospitalized patients with OUD compared with patients without the disorder, at 7.2% and 5.6%, respectively.
The sepsis patients with OUD tended to be younger, healthier, and more likely to be white compared with patients without OUD, according to the report. Moreover, the sepsis patients with OUD more often had endocarditis and gram-positive and fungal bloodstream infections. They also required more mechanical ventilation and had more ICU admissions, with longer stays in both the ICU and hospital.
The OUD patients accounted for 2.1% of sepsis-associated deaths overall, but 3.3% of those deaths in healthy patients, and 7.1% of deaths among younger patients, according to the report.
Those findings provide some clues that could help guide clinical practice, according to Dr. Martin. For example, the data show a nearly fivefold increased risk of endocarditis with OUD (3.9% versus 0.7%), which may inform screening practices.
“While we don’t necessarily screen every sepsis patient for endocarditis, if it’s an opioid use disorder patient – particularly one with a bloodstream infection – then that’s almost certainly something you should be doing,” Dr. Martin said.
The data suggest gram-positive bacterial and fungal infections will more likely be encountered among these patients, which could guide empiric treatment, he said.
Providers specializing in OUD should have a heightened awareness of the potential for infection and sepsis among those patients, and perhaps be more attuned to fever and other signs of infection that might warrant a referral or additional care, Dr. Martin added.
Dr. Alrawashdeh reported no disclosures related to the study.
