New Clinical Study Finds MolecuLight i:X® Point-of-Care Imaging Improved Sensitivity of Detecting Bacterial Burden in Surgical Site Wounds by 11-Fold

18 Gennaio 2022

Authors Suggest that Fluorescence Imaging of Bacterial Burden is Positioned to Change Contemporary Paradigms of Post-Surgical Wound Management

TORONTO, Jan. 18, 2022 /PRNewswire/ -- MolecuLight Inc., the leader in point-of-care fluorescence imaging for real-time detection of wounds containing elevated bacterial loads, announced the publication of  "Uncovering the high prevalence of bacterial burden in surgical site wounds with point-of-care fluorescence imaging"1 in International Wound Journal. The publication reports on the results of an analysis of 58 imaged and biopsied surgical site wounds from the 350-patient multi-centre FLAAG (fluorescence imaging assessment and guidance) clinical trial2.

Key findings of the study include:

The incidence of surgical wound complications, including surgical site infections ("SSI"), continue to rise and the development of an SSI is associated with a marked increase in morbidity, a 2-to 11-fold increase in mortality rate, and prolonged hospital stays3. Approximately 2-5% of surgical wounds in the US develop an SSI7-10 at an annual cost of up to $10 billion4-7. This includes extended hospital stays, readmissions, and more resources required to manage complications."While early identification and management of high bacterial burden is critical for the prevention of surgical site infections, this study shows that pathogenic bacterial burden is present in most (>75%) surgical wounds that are referred to a wound specialist, but is largely asymptomatic and therefore goes undetected, delaying bacterial management strategies", says lead author Associate Professor Sandy-Hodgetts, Centre for Molecular Medicine & Innovative Therapeutics, Murdoch University & Senior Research Fellow, School of Biomedical Sciences, University of Western Australia and the Founder and inaugural President of the International Surgical Wound Complications Advisory Panel (ISWCAP). "Due to its ability to quickly and reliably detect bacterial burden at the point-of-care, fluorescence imaging using the MolecuLight device is positioned to change contemporary paradigms of post-surgical wound management".

These findings are part of an important initiative by the International Surgical Wound Complications Advisory Panel (ISWCAP) to study surgical site infections on a global scale and highlight the need for more objective diagnostic techniques to support the early and accurate detection of clinically concerning bacterial burden in surgical wounds. The authors note that this is the first study reporting the use of an advanced diagnostic device for the visualisation and diagnosis of bacterial burden in surgical wounds.

"MolecuLight fluorescence imaging technology allows clinicians to see into the wound. The point-of-care imaging device enables clinicians to detect and manage elevated levels of bacteria to inform our decision-making," says Dr. Thomas Serena, the publication's contributing author, Founder and Medical Director of The SerenaGroup®, and Vice President of ISWCAP.  "Management of bacterial burden should always begin with wound hygiene strategies (e.g., cleansing, debridement), and only escalate to antibiotics when essential."
