The transition from intravenous (IV) to oral antibiotics is a crucial step in the treatment of patients with gram-negative bloodstream infections. However, a retrospective cohort study has revealed that fewer than half of hospitalized patients achieved this transition by day 7. This alarming finding raises concerns about the potential risks and burdens associated with prolonged IV antibiotic use. It also suggests that there may be disparities in the implementation of antimicrobial stewardship programs among hospitals, leading to varied rates of transition. In this article, we delve into the implications of these findings and explore the opportunities for improvement in managing gram-negative bloodstream infections.
The retrospective cohort study, which included over 4,500 patients across 24 hospitals, reported that only 43% of patients successfully transitioned from IV to oral antibiotics by day 7. Surprisingly, the rates of transition varied widely among the participating hospitals, despite their engagement in antimicrobial stewardship programs. This disparity raises concerns about the broader care landscape in the United States and the likelihood of even more significant challenges in institutions without access to infectious disease expertise or well-established antimicrobial stewardship programs. The variation suggests a need for standardized guidelines and protocols to ensure timely transitions and optimize patient outcomes.
Transitioning patients to oral antibiotics in a timely manner is critically important due to the potential risks associated with prolonged IV antibiotic treatment. These risks include phlebitis, venous thromboembolism, catheter occlusions, and catheter-related bloodstream infections. Furthermore, prolonged IV treatment poses significant inconveniences for patients and adds to the nursing workload. Recognizing the significance of timely transition, the authors of the study advocate for interventions aimed at facilitating early oral antibiotic transition.
Anurag Malani, MD, one of the researchers involved in the study, highlighted that even among the patients who remained on IV antibiotics, many were afebrile and clinically stable. This observation suggests that there are potential opportunities for earlier oral transition in this patient population. Implementing strategies to identify suitable candidates for oral antibiotics and actively engaging in their transition could significantly improve patient care and resource utilization.
The study included 4,581 hospitalized patients with gram-negative bloodstream infections from January through December 2019. The median age of the patients was 67 years, with 52.2% being men. Among those who transitioned to oral antibiotics, the most common sources of infection were the urinary tract, hepatobiliary sources, and intra-abdominal sources. In contrast, patients who remained on IV therapy had higher rates of comorbidities, fever or hypotension on day 5, the need for kidney replacement therapy, and delayed source control within 7 days.
A notable finding from the study was the shorter duration of treatment among patients receiving oral antibiotics. The median duration of antibiotic treatment for the oral antibiotic group was 11 days, compared to 13 days for the IV group. This significant reduction in treatment duration emphasizes the potential benefits of early oral transition in terms of patient recovery, resource optimization, and cost-effectiveness.
The study also outlined the most commonly prescribed oral antibiotics, which included fluoroquinolones, β-lactams, and trimethoprim-sulfamethoxazole. These findings suggest that these oral antibiotics are effective options for the treatment of gram-negative bloodstream infections. Further research and clinical trials are warranted to establish appropriate guidelines for the selection and dosing of oral antibiotics in this context.
The retrospective cohort study sheds light on the challenges associated with transitioning from IV to oral antibiotics in patients with gram-negative bloodstream infections. The disparities in transition rates among hospitals indicate a need for standardized protocols and guidelines to ensure timely transitions and improve patient outcomes. Early oral antibiotic transition presents an opportunity to optimize patient care, reduce risks associated with prolonged IV treatment, and streamline resource utilization. By actively identifying suitable candidates for oral antibiotics and facilitating their transition, healthcare providers can enhance the management of gram-negative bloodstream infections and improve overall patient wellbeing.
