I love and hate SSI prevention in equal measure. On the one hand, we have good evidence and strong guidelines around SSI prevention – but on the other hand, implementing these interventions to prevent SSI can be enormously tricky in practice. One key factor in preventing SSI is creating a well-closed wound in theatre. Surprisingly, there’s precious little data on how to measure what a well-closed surgical wound looks like. This qualitative study presents some potential indicators to measure good surgical wound closure in order to prevent SSI.
