The long-term objective is to quantify the journey of patients with hard-to-heal wounds to identify ideal intervention points that will lead to the best outcomes. This article summarises the findings, implications, limitations and suggestions for future research.</p><p><strong>Method: </strong>Qualitative data were self-reported from patients with hard-to-heal wounds (open for ≥4 weeks) in a pilot chatbot survey, (Wound Expert Survey (WES)) provided online in the US on Meta platforms (Facebook and Instagram) between 2021 and 2022.</p><p><strong>Results: </strong>The US national pilot survey attracted responses from 780 patients, 27 of whom provided a video testimonial.

Experiencing an ulcer, even for a few months, can have significant negative effects on a patient's QoL. Patients frequently had negative thoughts associated with their wound, and odour compounded these negative effects, leading to major or severe negative impacts on self-confidence. Households experienced a decline in income, due to both the direct reduction or loss of patient employment and the additional time spent by family members assisting in patient recovery. Thus, a variety of factors contribute to poor outcomes for patients with hard-to-heal wounds.

Among the many benefits of using MDT is its antimicrobial effect. Maggots secrete substances that are known to have antibacterial properties against both Gram-negative and Gram-positive bacteria. Clinically, this results in the effective eradication of pathogenic species and consequently, a faster healing process. The aim of this study was to evaluate the effect MDT has on the bacterial flora of hard-to-heal ulcers.</p><p><strong>Method: </strong>Patients with venous, mixed arteriovenous, decubitus, diabetic and neuropathic wounds were treated with larvae of <i>Lucilia sericata</i> enclosed in bags.
