A comprehensive scoring system to evaluate patient-centred risk factors regarding lower extremity amputation

Care of the patient with a presumed life- or limb-threatening lower extremity wound poses many challenges. The mindset regarding potential outcomes of such conditions is mostly driven by the experiences and expertise of those providing the care. This mindset generally appears as two primary actions presented to the afflicted patient: attempted resolution of the problem via medical, surgical or combination treatment, with the hope of low recurrence risk, or exacerbation and amputation-amputations at a level sufficient to, at least in the mind of the surgeon, eliminate the problem. Achieving the former outcome is dependent on a number of factors associated with both patient and caregiver. If healing is achieved, the secondary goal of prevention of recurrence may be no less arduous, with failure most likely resulting in amputation. Clearly, these considerations appear to be based more on the health professionals perception, of the patient's physical and medical status rather than on patient-centred considerations. This article will review considerations and recommendations for lower extremity amputation, and the short- and long-term implications. Based on our research, there is clear need for a set of criteria against which to weigh not just the medical issues, but also definitive patient-centred issues when considering a lower extremity amputation. We offer a set of patient-centred, easily verified and recognised criteria that we believe addresses this need. The goal of the Miller-Newgent Amputation Scale (MENACE) is to provide a decision base from which to consider and evaluate all factors in determining the need for a lower extremity amputation. This involves identification of patient-centred issues, which are likely to produce satisfactory short- and long-term physical and quality-of-life outcomes if the amputation does proceed.
