Association between duration of antimicrobial prophylaxis and postoperative outcomes after lumbar spine surgery

Extended Postoperative Antibiotic Prophylaxis Is Associated with No Clinical Value and Higher Projected Cost Following Adult Spinal Surgery: A Stratified Meta-Analysis and Probability-Based Cost Projections

» We aimed to determine the cost-effectiveness of different protocols of extended postoperative antibiotic prophylaxis (E-PAP) following adult spinal surgery.

» Both stratified (randomized controlled trials only) and nonstratified (all studies) analyses demonstrated that E-PAP has no significant value in reducing the rate of surgical site infection (SSI), deep SSI, or superficial SSI.

» Notably, the E-PAP protocols were associated with a significant increase in the length of hospital stay, resulting in an additional expenditure of $244.4 per episode for the E-PAP 72 hours protocol compared with PAP 24 hours and $309.8 per episode for the E-PAP >48 hours protocol compared with PAP <48 hours.

» E-PAP does not demonstrate any significant reduction in the rate of SSIs following spine surgery. However, these extended protocols were significantly associated with an increase in the length of hospital stay and higher overall projected costs.

Surgical and procedural antibiotic prophylaxis in the surgical ICU: an American Association for the Surgery of Trauma Critical Care Committee clinical consensus document

The use of prophylactic measures, including perioperative antibiotics, for the prevention of surgical site infections is a standard of care across surgical specialties. Unfortunately, the routine guidelines used for routine procedures do not always account for many of the factors encountered with urgent/emergent operations and critically ill or high-risk patients. This clinical consensus document created by the American Association for the Surgery of Trauma Critical Care Committee is one of a three-part series and reviews surgical and procedural antibiotic prophylaxis in the surgical intensive care unit. The purpose of this clinical consensus document is to provide practical recommendations, based on expert opinion, to assist intensive care providers with decision-making for surgical prophylaxis. We specifically evaluate the current state of periprocedural antibiotic management of external ventricular drains, orthopedic operations (closed and open fractures, silver dressings, local, antimicrobial adjuncts, spine surgery, subfascial drains), abdominal operations (bowel injury and open abdomen), and bedside procedures (thoracostomy tube, gastrostomy tube, tracheostomy).

What Is the Ideal Duration for Surgical Antibiotic Prophylaxis?

Background: Surgical antibiotic prophylaxis practice became common in the 1970s and has since become almost universal. The earliest articles used three doses over 12 hours with the first being administered before the start of the operation. Conclusions: The duration of prophylaxis has varied widely in practice over time, but an increasing body of evidence has supported shorter durations, most recently with recommendations in influential guidelines to avoid administration after the incision is closed.

Using antibiotics wisely

PURPOSE OF REVIEW

This review will describe role of shorter antibiotic therapies, early switch from intravenous to oral therapy, and artificial intelligence in infectious diseases.

RECENT FINDINGS

There is evidence that shorter courses of antibiotics are noninferior to standard durations of therapy. This has been demonstrated with Enterobacterales bacteremia that can be treated with 7 days of therapy, community acquired pneumonia with 3 days and ventilator associated pneumonia with just 7 days of antibiotic therapy. The conversion from intravenous to oral therapy in treating bacteremia, endocarditis and bone and joint infections is safe and effective and reduces line complications and costs. Also, for clean surgical procedures only one dose of antibiotic is needed, but it should be the most effective antibiotic which is cefazolin. This means avoiding clindamycin, removing penicillin allergies where possible for improved outcomes. Finally, the role of artificial intelligence to incorporate into using antibiotics wisely is rapidly emerging but is still in early stages.

SUMMARY

In using antibiotics wisely, targeting such as durations of therapy and conversion from intravenous antibiotic therapy to oral are low hanging fruit. The future of artificial intelligence could automate a lot of this work and is exciting but needs to be proven.
