Abstract

OBJECTIVE:

To compare healing outcomes at a wound healing centre both before and after the introduction of molecular pathogen diagnostics.

METHOD:

An IT consultant was recruited to analyse the medical records of patients at a wound healing centre, comparing patient groups from 2007 and 2009 - before and after the introduction of comprehensive molecular pathogen diagnostic methods.

RESULTS:

Before the implementation of molecular diagnostics, 244/503 patients (48.5%) healed completely, while after implementation 298/479 patients (62.4%) healed. Furthermore, based on survival analysis and after controlling for potential confounding factors, time to healing was significantly shorter in 2009 than 2007 (p<0.05). Specifically, biofilm-based wound care, along with the implementation of comprehensive molecular diagnostics for venous leg ulcers, pressure ulcers and diabetic foot ulcers and all wounds combined showed, respectively, 21%, 23%, 25% and 22% reductions in the time to healing. In addition, after implementing molecular diagnostics, the use of expensive fi rst-line antibiotics also declined in 2009, while a broader range of targeted antibiotics was used.

CONCLUSION:

The results of modern molecular pathogen diagnostic applications allow comprehensive evaluation of the microbial bioburden in chronic wounds. This comprehensive diagnostic in turn has led to a more precise and targeted therapeutic approach to wound care. With the comprehensive nature of molecular diagnostics future advances in topical patient specific therapeutics are now possible.
