Outcome and Prognosis
Achieving a closed wound is the beginning of a lifelong struggle to prevent recurrent ulceration at the surgery site or at a new site. Recurrence rates in the literature are reported to be as high as 90%.
Future and Controversies
Promising research in the field of growth factors and wound healing has shed light on the complex interactions that ensue at the wound surface and in the affected organism as a whole. This has led to the introduction of becaplermin (Regranex), recombinant human platelet-derived growth factor. This topical agent has been approved by the US Food and Drug Administration (FDA) for the treatment of lower extremity, diabetic neuropathic ulcers that extend into the subcutaneous tissue or beyond. Studies are underway to possibly expand the approved indications for this drug to include other wounds. Other growth factors also are being evaluated for use in human clinical settings. This expanding field surely will contribute further applications of basic science to clinical wound healing, with improvement of our understanding and patient care.
Ethical considerations
As a final note, one should consider the ethics of pressure sore treatment. The aggressive treatment of pressure ulceration is outlined in this article. This treatment certainly is indicated for one subset of patients who have pressure ulceration, that is, acutely hospitalized patients with a recoverable illness.
For other persons, such as chronically or terminally ill patients with long-standing or recurrent ulceration, aggressive treatment may not be in their best interests. In these instances, the wishes of the patient or the patient's family should be weighed carefully. In many cases, medical care and the maintenance of patient comfort, rather than the institution of major invasive procedures, should be the goals.
