The 1980's brought an increase of bacterial resistance to antibiotics, and MDT was revisited as a procedure to assist in the treatment of non-healing wounds that were recalcitrant to antibiotics and when surgical intervention was not an option. Dr Ronald Sherman, and associates from the Veterans Affairs Medical Centre, California, pioneered the reintroduction of MDT. His clinical trials indicated that MDT was several times more efficient at debriding infected and gangrenous wounds (and healing them more rapidly) when compared with other modern non-surgical treatments. In the last 15 years, thousands of patients with bedsores, leg ulcers, diabetic foot wounds and post surgical infections have been successfully treated by MDT. At present, health care facilities in the UK, Europe and the USA now produce thousands of medicinal maggots per week for therapists. In the UK alone, MDT has been estimated at saving the national health system over one billion dollars annually, and is now recognised as a procedure that can be officially prescribed and claimed on health care benefits.
