CLINICAL DO'S & DON'TS: Obtaining a wound culture specimen
When a wound culture is deemed necessary, what's the best technique for obtaining S. Audit of wound swab sampling: why protocols could improve practice.what
While it is accepted accurate identification of infecting organisms is crucial in guiding treatment of periprosthetic joint infection PJI , there remains no consensus regarding the best method for obtaining cultures. We compared the yield of intraoperative tissue samples versus swab cultures in diagnosing PJI. Tissue and swab cultures three each were collected prospectively during a consecutive series of aseptic and septic revision arthroplasties from October to April The tissues and swabs were taken from standardized regions of the joint. After excluding 39 reimplantation procedures, we included cases 74 hip, 43 knee; 30 septic, 87 aseptic for analysis.
Wound management involves a comprehensive care plan with consideration of all factors contributing to and affecting the wound and the patient. No single discipline can meet all the needs of a patient with a wound. Age related skin changes see comparison figures below-normal on the left, aging on the right include thinning and atrophy of epithelial and fatty layers.

I see it all of the time. Wound care clinicians performing wound cultures incorrectly, or obtaining cultures just because there is an open wound. With this being said, there are certain health care settings where per protocol, swab cultures are taken on every wound, even without signs and symptoms of infection. But I want you to always ask yourself a few questions when determining if a culture is warranted: Are there signs and symptoms of infection? Is there an odor after the wound has been cleansed? Has wound healing stalled?
NCBI Bookshelf. Concordance in diabetic foot ulceration: a cross-sectional study of agreement between wound swabbing and tissue sampling in infected ulcers. Health Technology Assessment, No. For infected DFUs, the accurate identification of pathogens, rather than colonising bacteria, is a prerequisite for selecting targeted antibiotic therapy to ensure optimal patient outcomes and avoid the acquisition of antibiotic resistance. The primary objective of the COncordance in DIabetic Foot Infection CODIFI main agreement study was to assess the level of agreement and patterns of disagreement between culture results from specimens taken by both surface swabs and tissue sampling from DFUs with suspected infection. We were interested in comparing three major microbiological parameters:. Secondary objectives of the main agreement study were to compare rates of sampling-related adverse events AEs and the costs of sampling using each of the two techniques.

When and how to culture a chronic wound
Increased antibiotic resistance in many organisms makes it vital that any infection is treated in the most appropriate way. - When it comes to microbiologic monitoring of a wound, qualitative and quantitative cultures are the most commonly used techniques. In the outpatient wound care environment, you would generally obtain qualitative cultures As we all know, the swab method is easy, inexpensive and is a non-invasive method that gives you specific information about bacterial contamination in the superficial wound.

Chronic wound infections are a significant healthcare burden, contributing to increased morbidity and mortality, prolonged hospitalization, limb loss, and higher medical costs. For wound care providers, the goal is to eliminate the infection before these consequences arise. Most chronic wounds are colonized by polymicrobial aerobic-anaerobic microflora. However, practitioners continue to debate whether wound cultures are relevant. See Differentiating acute and chronic wounds. With chronic wounds, many clinicians find it more practical to treat local signs and symptoms, such as increased pain and drainage, erythema, friable granulation tissue, and edema.
