The Benefits of Evidence-Based Medicine
While it is always essential that any chosen medical intervention is as effective as possible, this is particularly true in times of economic difficulty when resources are limited and waste is not an option. To maximize the effectiveness of available resources, the practice of evidence-based medicine becomes increasingly important, as well as the use of guidelines that consider the cost-effectiveness of treatments.
What is Evidence-Based Medicine?
Evidence-based medicine has been defined as the “conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients.”1 The practice of evidence-based medicine involves combining individual clinical expertise with the best available external clinical evidence from systematic research.
A review of the effect of informed treatment decisions on improving patient care in wound management was recently published,2 based on a comprehensive Medline and OvidSP literature search using the MESH terms evidence-based practice and wounds and injuries.
Modern Therapies Save Money
The review found that certain modern therapies, although costly, can provide cost savings overall. One example is negative pressure wound therapy, which, although considerably more expensive than routine dressings in the treatment of diabetic foot ulcers and traumatic and postsurgical wounds, can lead to savings through fewer surgical procedures, less-frequent monitoring, and fewer outpatient treatment visits.3-6
Interestingly, however, the review also found that new and expensive interventions are not always necessarily more effective, despite an underlying expectation to the contrary. For example, although the use of modern dressings is widespread, these dressings have not always been shown to provide a clinical advantage over conventional dressings. The authors recommend, therefore, that wound care professionals resist the routine use of new and more expensive dressings in the absence of good quality clinical evidence for their benefit over existing products.
If you are interested in learning more about evidence-based medicine and how it may be used to enhance your own treatment practices, consider gaining a recognized certification in wound care.
