Among patients receiving outpatient parenteral antibiotic therapy, or OPAT, follow-up with an infectious disease physician within 2 weeks was associated with a lower risk for all-cause 30-day readmission, according to results from a pair-matched case-control study.
John J. Zurlo, MD, director of the division of infectious diseases at Thomas Jefferson University in Philadelphia, and colleagues said studies have shown that rates of of 30-day readmission often exceed 20% in OPAT patients.
“Prior guidelines for managing patients on OPAT suggested weekly follow-up. Yet that recommendation was based on expert opinion rather than hard data. Moreover, in practice, this recommendation was unlikely to be adhered to,” Zurlo told Infectious Disease News. “Our study was the first to show that early follow-up positively impacts an important outcome measure, that is 30-day readmission.”
For the study, Zurlo and colleagues included 1,102 patients enrolled in the OPAT program at Thomas Jefferson University between January 2012 and December 2014.
According to the findings, readmission within 30 days of discharge occurred for 18% of patients. Of the readmissions, almost 40% occurred within 7 days after discharge, and 46% of the patients were readmitted because of OPAT-related reasons. The most common reason for OPAT-related readmission was worsening or complication of the initial infection, according to Zurlo and colleagues.
An analysis showed a higher risk for readmission among patients with immunosuppression compared with nonsuppressed patients, the researchers reported. They said 30-day readmission appeared to be related to antimicrobial use, with patients receiving fluoroquinolones, metronidazole, antifungals or three or more antimicrobials experiencing higher risks for readmission. Conversely, Ceftriaxone use was associated with a lower risk for readmission, according to the study.
Zurlo and colleagues calculated that an ID follow-up within 2 weeks of discharge resulted in a significantly lower risk for 30-day readmission (adjusted OR = 0.33; 95% CI, 0.19-0.59) than if the patients were followed-up after 2 weeks or not at all.
“While our findings need to be validated by prospective study, we and others who manage OPAT patients should make a concerted effort to closely follow patients during the first 2 weeks following hospital discharge in order to detect the earliest signs of treatment failure or adverse reactions to the antibiotic(s) being administered,” Zurlo said. – by Marley Ghizzone
