Positive Predictive Value (PPV) of Pseudomonas Aeruginosa
2020年3月4日 更新者：MolecuLight Inc.
A Prospective, Single-blind Evaluation of the Positive Predictive Value (PPV) of the MolecuLight i:X™ Imaging Device to Predict the Presence of Pseudomonas Aeruginosa in Chronic Wounds
This is a non-randomized, single-blind post market clinical follow-up study for which 65 patients will be imaged at Rouge Valley Centenary Hospital (Scarborough and Rouge Hospital) who present with a chronic wound and are receiving standard wound care treatment.
The MolecuLight i:X imaging device will be used by the study clinician as an adjunctive tool in the assessment of the wound and will be used to guide the targeted sampling of a wound (with curettage scraping), as per current standard of care in the principal investigator's wound care clinic.
The acquired tissue sample will then be analysed using conventional gold standard semi-quantitative culture methods to determine bacterial species present, also as per current standard of care in this clinic.

研究人群
Patients will be treated at the Scarborough and Rouge Hospital as per the standard of care, which includes use of the MolecuLight i:X imaging device and targeted sampling of regions with bacterial fluorescence for microbiological analysis.
Patients will be identified as candidates and consented by the study's principle investigator.
The images which would be acquired for this study are currently part of the routine clinical wound care assessment process in the principle investigator's wound care clinic.
However, during study enrollment subjects will be given as much time as required for their understanding of the basic study, to understand that their participation is optional, to understand that they will receive standard of care wound treatment whether or not they choose to participate, and to have any potential questions addressed.
描述
Inclusion Criteria:
- Male or female patients presenting with a chronic wound (wound duration > 4 weeks) e.g. diabetic foot ulcer, venous leg ulcer, pressure ulcer, or other acceptable aetiology
- 18 years or older
Exclusion Criteria:
- Treatment with an investigational drug within 1 month before study enrolment
- Inability to consent to medical photography (i.e. inability to understand consent process)
- Any contra-indication to routine wound care and/or monitoring
- Prior participation of the patient in this study (for the same wound or a different wound).
