Traumatic stress symptoms following a lower limb amputation in diabetic patients: a longitudinal study

Psychosocial patient perspectives following major lower-limb amputation due to vascular aetiology: a protocol for a systematic meta-aggregation study

INTRODUCTION

Persistent psychosocial problems in people with lower-limb amputation due to vascular aetiology indicate a great need for long-lasting holistic rehabilitation. An in-depth understanding of the psychosocial problems is essential for the guidance of health professionals in meeting and normalising patients' experiences and emotions. Furthermore, identifying the psychological problems may help develop effective rehabilitation and counselling programmes. This meta-aggregation study aims to explore the psychosocial perspectives of individuals who have undergone a major lower-limb amputation due to vascular aetiology during the post-discharge rehabilitation phase.

METHODS AND ANALYSIS

A systematic meta-aggregation study will be performed to identify full-text, peer-reviewed journal articles reporting on patients' psychosocial perspectives on major lower-limb amputation due to vascular aetiology from post-discharge to several years afterward. The databases Embase, CINAHL Ultimate, APA PsycInfo, PubMed and Scopus will be searched with no limitations regarding the publication year. Studies that satisfy the eligibility criteria will be critically appraised using an acknowledged checklist and synthesised using the Joanna Briggs Institute three-phase approach for the synthesis of meta-aggregation studies. The GRADE-CERQual (Grading of Recommendations Assessment, Development and Evaluation- Confidence in Evidence from Reviews of Qualitative research) tool will be used to determine the level of confidence in the qualitative evidence, and the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) reporting guidelines will be followed throughout the review process.

ETHICS AND DISSEMINATION

Ethical approval is not required for the study, as the review is built on pre-existing available data in the literature. Findings from the review will be disseminated through publication in a peer-review journal.

Dakin's solution in the treatment of severe diabetic foot infections

Acute necrotising diabetic foot (DF) infections are common, costly, and do not infrequently result in debilitating major lower-extremity amputations. Dakin's solution is a long-standing topical antiseptic that has shown benefit in this clinical setting, but its use is undermined by a presumed risk of cytotoxicity. In this single-centre case series, we retrospectively evaluated 24 patients with severe necrotising DF infections treated with a cyclical instillation of Dakin's solution at a referral multidisciplinary DF unit. Most patients achieved favourable outcomes in infection control and limb salvage, with only one patient (4.2%) requiring a major (at or above-the-ankle) amputation. The mean time to complete or near-complete wound granulation was 5.4 weeks. Of the 12 patients who completed 12 or more months of longitudinal follow up, only 2 (12.2%) had a wound recurrence. In this severe DF infection patient cohort, Dakin's solution led to a clinically meaningful improvement. No remarkable impairment in the wound-healing process was observed.
