Background: Surgical site infection is a significant cause of morbidity and mortality following caesarean delivery. Objective: To determine whether standardising intraoperative irrigation with 0.05% chlorhexidine gluconate during caesarean delivery could decrease infection rates. Methods: This was a process improvement project involving 742 wo...

The standard of practice for perioperative hair removal is largely based on research that is outdated and underpowered. Although there is evidence to support the practice of clipping instead of shaving, current recommendations are to remove hair only when absolutely necessary. Human hair is bacteria‐laden and challenging to disinfect, and clipping...

Background: A growing body of research has demonstrated that manual cleaning and disinfection of the operating room (OR) is suboptimal. Residual environmental contamination may pose an infection risk to the surgical wound. This study evaluates the impact of a visible-light continuous environmental disinfection (CED) system on microbial surface con...

The current practice of perioperative hair removal reflects research-driven changes designed to minimize the risk of surgical wound infection. An aspect of the practice which has received less scrutiny is the clean-up of the clipped hair. This process is critical. The loose fibers represent a potential infection risk because of the micro-organisms...

Surgical site infections (SSIs) are among the most common and expensive of all health care–associated infections, and as many as 50% are considered preventable. Surgical care bundles, which involve a small set of reliably performed evidence-based practices, may effectively reduce SSI rates. However, closure of the surgical incision is one aspect of...

Accurate and rapid antimicrobial susceptibility testing with pathogen identification in bloodstream infections is critical to life results for early sepsis intervention. Advancements in rapid diagnostics have shortened the time to results from days to hours and have had positive effects on clinical outcomes and on efforts to combat antimicrobial re...

The development of navigation technology facilitating MRI-guided stereotactic neurosurgery has enabled neurosurgeons to perform a variety of procedures ranging from deep brain stimulation to laser ablation entirely within an intraoperative or diagnostic MRI suite while having real-time visualization of brain anatomy. Prior to this technology, some...

The global push to combat the problem of antimicrobial resistance has led to the development of antimicrobial stewardship programs (ASPs), which were recently mandated by The Joint Commission and the Centers for Medicare and Medicaid Services. However, the use of topical antibiotics in the open surgical wound is often not monitored by these program...

Neurosurgical laser ablation is a relatively new but rapidly growing application of stereotactic neurosurgery that allows neurosurgeons to treat many previously untreatable conditions with the added benefit of shorter hospitalizations and recovery times. The vast majority of these procedures, however, are performed using a multisite workflow patter...

Environmental disinfection has become the new frontier in the ongoing battle to reduce the risk of health care-associated infections. Evidence demonstrating the persistent contamination of environmental surfaces despite traditional cleaning and disinfection methods has led to the widespread acceptance that there is both a need for reassessing tradi...

Efforts to reduce the incidence of hospital-acquired infection (HAI) remain a significant focus for health care facilities, particularly in this era of drug-resistant organisms. With as many as 1 in every 25 hospitalized patients acquiring an infection, the need to minimize the risk of HAIs is widely recognized as critical. Advances in the fields o...

Efforts to reduce health care-associated infections (HAIs) have grown in both scale and sophistication over the past few decades; however, the increasing threat of antimicrobial resistance and the impact of new legislation regarding HAIs on health care economics make the fight against them all the more urgent. On-demand polymerase chain reaction (P...

Surgical wound irrigation has long been debated as a potentially critical intraoperative measure taken to prevent the development of surgical site infection (SSI). Unlike many other SSI prevention efforts, there are no official practice guidelines or recommendations from any major medical group for the practice of surgical irrigation. As a result,...

Objective: To assess the bioburden associated with surgical scrub garments separated into eight categories based on single-use/re-usable status, use status (prior to use versus after use), and, for re-usable scrub garments, laundering mechanism (facility-laundered, third-party laundered and home-laundered). The study's aim was to determine whether...
