Comparison of the demographic and clinical characteristics, functional status and quality of life of lower extremity amputees to identify the reason for undergoing amputation

A Systematic Review of Cognitive Functioning and its Relationship to Outcomes Following Amputation Secondary to Vascular Etiology

Amputation is a major life event, impacting on all aspects of daily living, and has the goal of achieving maximal patient mobility and independence. The level of cognitive function of those patients who are assigned a prosthesis is an important consideration in the rehabilitation process. Therefore we set out to understand the relationship between cognitive functioning and functional and/or health outcomes following amputation secondary to a vascular condition. This systematic review searched five databases: PsycINFO, Cumulative index to nursing and allied health literature (CINAHL), Scopus, MEDLINE, and Web of Science for peer-reviewed English language articles that met the inclusion criteria. Two authors independently assessed suitability for inclusion, determined biases (Cochrane risk of bias assessment) and extracted data. Results are presented as associations determined on the balance of probabilities. A total of 14 studies were included, with a total of 6891 participants across six domains. Evidence of an association between cognitive function and prosthetic use, mobility and activities of daily living (ADLs) were found. Evidence revealed 83.3% association for cognition and mobility, 66.7% for cognition and ADL, and 62.5% for cognition and prosthetic use. The evidence was indeterminate for an association between cognitive function and living/discharge destination. There was insufficient weight of evidence to determine an association between cognitive function and general health or social participation. The associations found between cognitive function and prosthetic use, mobility and ADL highlight the need for cognitive assessment to form part of the postoperative pathway for vascular amputees.

Patient-reported Outcome Measures following Traumatic Lower Extremity Amputation: A Systematic Review and Meta-analysis

BACKGROUND

Outcomes after traumatic major lower extremity amputation (MLEA) have focused on surgical complications, despite the life-altering impact on patients. With advances in the surgical management of MLEA, a heightened need for consistent reporting of patient-centered outcomes (PCO) remains. This meta-analysis assesses articles for the prevalence and methods of PCO reporting among traumatic MLEA studies.

METHODS

An electronic database search was completed using Ovid MEDLINE for studies published between 2000 and 2020. Studies were included that reported any outcome of traumatic MLEA. Weighted means of outcomes were calculated when data were available. The prevalence of PCO was assessed in the categories of physical function, quality of life (QOL), psychosocial, and pain. Trends in PCO reporting were analyzed using Pearson's chi-squared test and analysis of variance when appropriate.

RESULTS

In total, 7001 studies were screened, yielding 156 articles for inclusion. PCO were evaluated in 94 (60.3%) studies; 83 (53.2%) reported physical function and mobility outcomes, 33 (21.2%) reported QOL and satisfaction measures, 38 (24.4%) reported psychosocial data, and 43 (27.6%) reported pain outcomes. There was no change in prevalence of PCO reporting when comparing 5-year intervals between 2000 and 2020 (P = 0.557).

CONCLUSIONS

Optimization of function and QOL following traumatic MLEA has become a cornerstone of surgical success; however, only 60% of studies report PCO, with no trend over the last two decades suggesting improvement. As healthcare progresses toward patient-centered care, this inconsistent means of reporting PCO calls for improved inclusion and standardization of instruments to assess function, QOL, and other patient-focused measures.
