Can we ‘see’ biofilm in chronic wounds?

Dear Colleague,

I am a PhD student at the School of Nursing and Midwifery, University of Galway, Ireland, and my area of interest is diagnosis of biofilm in chronic wounds.

I have completed a comprehensive scoping review of the literature to derive a list of signs and symptoms currently reported to be indicative of biofilm in chronic wounds.

I have generated a list of signs and symptoms based on the results of the scoping review, and I now require your expert opinion to refine it further via a 2-round electronic Delphi survey in which you will be asked to rate each sign/symptom along a 9-point Likert scale ranging from ‘not likely’ to ‘highly likely’ to be indicative of biofilm in chronic wounds.

The results of this survey will be validated against a gold standard biopsy taken from consenting persons with diabetic foot ulceration in the clinical phase of my PhD project.

Should you wish to consider participating, I would direct you to the attached Participant Information Leaflet and if you decide to proceed, I would ask you to click on this link which will take you to round one of the survey.  You will receive a reminder to complete message one week after receiving this invitation, and we will send you a link to round 2 within six weeks followed by a single reminder to complete message.

I sincerely hope that you will agree to participate in this work, and I would ask you to consider forwarding this message to colleagues of yours in the field who may not be members of this organisation. 

For any queries you can contact me at

Yours sincerely,
