Background and study aims
Wound infections are a common complication after surgery, which are a major cost for the NHS. The skin usually acts as a barrier against infection, protecting the blood and internal organs. When a cut is made during an operation to allow the surgery to be performed (surgical site), bacteria can potentially enter the body causing an infection. Wound dressings are commonly used to prevent infections of surgical sites in adults, however this practice is controversial. There is not enough evidence to say that wound dressings can help prevent surgical site infections (SSI). For example, in children it is rare to use wound dressings after surgery and the rate of SSI’s does not seem to have been affected by this. Previously, healthcare professionals and patients were interviewed, in order to find out their opinions about different types of dressings. The aim of this initial study is to look at the use of different would dressings in order to reduce the amount of SSI’s. This study will also show whether it would be feasible to carry out a larger study looking at the use of different dressings on surgical wounds.
Who can participate?
Adult surgery patients who be having subcuticular sutures for wound closure.
What does the study involve?
Participants are randomly allocated into one of three groups. After undergoing their scheduled surgical procedure, the surgical site is sewn up with stiches (sutured) and then treated in different ways. For those in the first group receive a “simple dressing”. This involves a covering that it directly placed over the whole of a closed-up wound. Those in the second group receive a “tissue adhesive-as-a-dressing”. This is “glue” that is applied directly to the skin to “seal” the wound edges together. Those in the third group do not receive any covering of their wound after their operation. Thirty days later, all participants visit the clinic for a follow up examination of their wound.
What are the possible benefits and risks of participating?
This study does not have any specific benefits for participants, however it will help increase knowledge which could help future patients. There are no risks of participating in this study, as all three techniques are currently used by surgeons. If a wound problem occurs (e.g. infection or leakage) it will be treated in the normal way.

Scientific title | The Bluebelle Study: a feasibility study of three wound dressing strategies in elective and unplanned surgery – Phase B |
Study objectives | This pilot randomised controlled study is to establish whether it is possible to carry out a major randomised study to compare the effectiveness and cost-effectiveness of simple dressing, tissue adhesive-as-a-dressing and no dressing to: reduce surgical site infection (SSI) and improve aspects of wound management and patients’ experience of the care of their surgical wounds following elective and unplanned abdominal and obstetric (caesarean section) surgery. |
Ethics approval(s) | NHS Health Research Authority - NRES Committee South West - Frenchay. 24/02/2015, ref: 15/SW/0008 |
Health condition(s) or problem(s) studied | Surgical site infections |
Intervention | Participants, confirmed as having provided consent and as eligible for the study, will be randomised via a secure web-based database. Participants will be randomised to one of six groups, comprising all permutations of three wound dressing strategies (see below) and two times of disclosure of allocation to a dressing strategy (before or after wound closure). 1. Simple Dressing: A covering (opaque or transparent) that is directly applied to an already closed wound, over the entirety of the wound. It has adherent properties around its perimeter, or, its entire surface which is in contact with the skin. It may or may not have absorbent properties. 2. Tissue adhesive-as-a-dressing: Tissue adhesives are topical skin adhesives and in this study they will be applied to the surface of an already closed primary wound, acting as a dressing. They will not be applied with the intention to close the wound (i.e. below skin level), and will be applied according to the manufacturers’ instructions for use after wound closure. 3. ‘No’ dressing: For those allocated to no dressing, at the end of the operation when the skin has been closed, no dressing at all or tissue adhesive is applied to the wound. The wound is therefore left exposed without a covering as is the standard approach for many types of surgery. For all of the interventions, a simple gauze swab can be applied to an area that is, for example, oozing. This may be taped in place temporarily (but not around its entire perimeter) and will not have therapeutic properties. If the oozing continues the clinical team may apply any dressing of choice to the wound(s) (or re-suture it if necessary). This will be documented in the CRFs. Wounds will be treated pragmatically and dressings left on as per normal practice. The follow-up duration is 4-8 weeks from wound closure, (the same for the 3 arms) and includes: Completion of: a questionnaire measure relating to the participant's management of the wound by a health care professional within 24 hours prior to discharge) and a questionnaire relating to the experience of the wound(s) by the participant within 48 hours of discharge. (Day Cases: Completion of Wound Experience and Practical Wound Management questionnaires within 48 hours of discharge). On about day 15 and, where possible, at any time the participant considers there is a problem with their wound: Completion of an EQ-5D-5L (electronically or paper version if no access to electronic version). For the 4-8 week follow-up assessment (which can be by phone or at clinic visit/home visit for women who have had a C-section): Completion of a participant reported measure of SSI prior to a clinician assessment and a health status questionnaire (EQ-5D 5L) and provide information on any adverse events and use of health services since discharge from hospital. The clinician will complete a standard reference assessment and then the SSI measure. Wound photos may be taken, with appropriate consent and in adherence to local policy, by clinicians (in theatres and/or at 30 day follow-up) and/or participants (for 30 day assessment and at any time they consider there to be a problem with their wound(s). Photos will be submitted to a secure database and will facilitate the exploration of a method for remote and blinded assessment of wounds using digital photography. |
Intervention type | Procedure/Surgery |
Primary outcome measure | To establish whether recruitment into the main trial is possible, by recording the number of patients screened, eligible and randomised into the pilot trial. |
Secondary outcome measures | 1. Health status is measured using the EQ-5D-5L will be collected at baseline, day 15, 4-8 weeks and between these time points if a participant considers that there is a problem with the wound(s) 2. Participant symptom experience is measured using the Wound Experience Questionnaire will be completed within 48 hours of discharge 3. Practical wound management is measured using the Wound Management Questionnaire will be completed by a nurse up to 24 hours before discharge if the participant is an inpatient or up to 48 hours after discharge if the participant is a day case 4. Surgical site infection post discharge is measured using the Wound Healing (SSI) questionnaire will be completed by the participant and a member of the research team at the 4-8 week assessment. A member of the research team will also complete a reference SSI assessment at the 4-8 week assessment. 5. Qualitative research will be carried out alongside the trial to investigate facilitators and barriers to recruitment and possible reasons for non-adherence |
