The Impact of Decline in Activities of Daily Living (ADL) of Patients With Critical Limb Ischemia (CLI) After Endovascular Treatment

Prosthesis use and the change in activities of daily living following below-knee amputation in patients undergoing hemodialysis

INTRODUCTION

Patients undergoing hemodialysis are at an increased risk of peripheral arterial disease, amputation of lower extremities, and decline of activities of daily living. Although a prosthesis is used to support activities of daily living, no previous study reported the association of prosthesis use with the change in activities of daily living following leg amputation in hemodialysis patients. The purpose of this study was to compare the changes in activities of daily living following amputation between those who created a prosthesis and those who did not.

METHODS

This study was a single-center, retrospective observational study. We screened medical records for hemodialysis patients who underwent below-knee amputation (BKA) and activities of daily living were examined two times with the functional independence measure (FIM) before BKA and at discharge. They were divided into two groups according to the creation of a prosthesis.

FINDINGS

We identified 28 eligible patients, among whom 12 patients used a prosthesis (prosthesis group), whereas 16 patients did not (non-prosthesis group). The FIM score was significantly decreased following BKA in the non-prosthesis group, whereas it was not significantly changed in the prosthesis group. The change in FIM score was significantly different between the two groups, and the difference remained significant after considering potential confounders.

DISCUSSION

The results of this study showed that use versus nonuse of a prosthesis was an independent factor associated with changes in activities of daily living in hemodialysis patients following BKA, supporting the important role of a prosthesis in maintaining activities of daily living in hemodialysis patients who need BKA.

Prognostic factors for delayed healing of complex wounds in adults: A scoping review

Complex or hard-to-heal wounds continue to be a challenge because of the negative impact they have on patients, caregivers, and all the associated costs. This study aimed to identify prognostic factors for the delayed healing of complex wounds. Five databases and grey literature were the sources used to research adults with pressure ulcers/injuries, venous leg ulcers, critical limb-threatening ischaemia, or diabetic foot ulcers and report the prognostic factors for delayed healing in all care settings. In the last 5 years, a total of 42 original peer-reviewed articles were deemed eligible for this scoping review that followed the JBI recommendations and checklist PRISMA-ScR. The most frequent prognostic factors found with statistical significance coinciding with various wound aetiologies were: gender (male), renal disease, diabetes, peripheral arterial disease, the decline in activities of daily life, wound duration, wound area, wound location, high-stage WIfI classification, gangrene, infection, previous ulcers, and low ankle brachial index. It will be essential to apply critical appraisal tools and assessment risk of bias to the included studies, making it possible to make recommendations for clinical practice and build prognostic models. Future studies are recommended because the potential for healing through identification of prognostic factors can be determined, thus allowing an appropriate therapeutic plan to be developed.

WIfI Classification Based Analysis of Risk Factors for Outcomes in Patients with Chronic Limb Threatening Ischaemia after Endovascular Revascularisation Therapy

OBJECTIVE

The evaluation of limb status with the Wound, Ischaemia, and foot Infection (WIfI) classification and the assessment of patient risks combined with systemic factors, are recommended in patients with chronic limb threatening ischaemia (CLTI). However, there is little evidence of the application of the WIfI classification in the Chinese population. This study aimed to verify the use of the WIfI classification in a Chinese patient population, and to further identify local and systemic independent predictors of adverse CLTI outcomes.

METHODS

A total of 474 patients who underwent endovascular therapy (EVT) for CLTI in a tertiary hospital between July 2017 and September 2020 were included in this retrospective study. The outcomes included one year major adverse limb events (MALEs), one year all cause mortality, and one year amputation free survival (AFS). Cox regression was used to analyse the association between risk factors and adverse outcomes.

RESULTS

In total, 104 (21.9%) all cause deaths were recorded. The rate of MALEs was 17.5%, while the AFS was 71.9%. Multivariable analysis revealed that a body mass index (BMI) < 18.5 kg/m2 (p = .002), a left ventricular ejection fraction (LVEF) < 50% (p < .001), and WIfI wound grade (p < .001) were independent risk factors for MALEs, while age ≥ 77 years (p = .031), BMI < 18.5 kg/m2 (p < .001), coronary heart disease (p = .040), and WIfI clinical stages (p = .021) were independent risk factors for death in patients with CLTI. Age ≥ 77 years (p = .003), BMI < 18.5 kg/m2 (p < .001), coronary heart disease (p = .012), LVEF < 50% (p < .001), WIfI wound grade (p = .004), and WIfI clinical stages (p = .044) were independently associated with a decreased AFS rate.

CONCLUSIONS

This study has confirmed the predictive ability of the WIfI classification for Chinese patients with CLTI who underwent EVT. Wound grade was the most sensitive and important risk factor of the three components of WIfI. In addition, systemic factors should be considered to ensure a more accurate prognosis prediction and appropriate clinical decision making in patients with CLTI.

Physical and psychological functioning of patients with chronic limb ischemia during a 1-year period after endovascular revascularization

OBJECTIVE

Symptoms of peripheral artery disease (PAD) and patients' physical and psychological status are related in a vicious circle. The aim of this study was to determine the relationships between improvement in parameters of PAD after endovascular procedures and changes in patients' physical and psychological status.

METHODS

We studied 140 consecutive PAD patients: 50 patients with chronic limb-threatening ischemia (CLTI), 50 patients with intermittent claudication (IC) undergoing an endovascular procedure, and 40 IC patients who were not qualified for leg revascularization. All participating patients were assessed at the beginning of the study and at 3 and 12 months of follow-up; scores taken included: ankle-brachial index, 6-minute walking test distance, Barthel index, activities of daily living (ADL) index, instrumental activities of daily living (IADL) index, Mini-Mental State Examination (MMSE), and Hospital Anxiety and Depression Scale (HADS).

RESULTS

After 12 months of follow-up, an improvement in PAD-related symptoms following leg revascularization had been maintained in 56% of the patients with CLTI and in 68% of those with IC. Twelve months after endovascular leg revascularization, the scores in respect of ADL, IADL, and MMSE had increased, and scores for HADS had decreased in both CLTI and IC patients. A higher baseline score in the IADL index was associated with a reduction in the 1-year cardiovascular event risk (OR; 95% CI: 0.70; 0.54-0.91; P < .01).

CONCLUSIONS

In PAD patients, endovascular procedures not only improved PAD-related symptoms, but also ameliorated patients' physical state, improved cognitive function, and reduced depression.
