Chronic wounds present a large burden to our healthcare system and are typically marked by a failure to transition out of the inflammatory phase of wound healing. Venous leg ulcers (VLUs) represent the largest portion of chronic wounds. A pilot study of eleven (11) patients with VLUs seen over a 12-week period was undertaken utilizing RNA sequencing of wound biopsies and plasma cytokine levels to determine if biomarkers could be identified that would distinguish between wounds which heal versus those that do not. Chronic wounds were found to have increased expression of genes relating to epithelial-to-mesenchymal transition (EMT), cartilage and bone formation, and regulation of apical junction. Plasma cytokine levels showed predictive potential for IL-15 and RANTES, which were found to increase over time in patients with healed wounds. Further research is needed to validate these biomarkers as well as additional study of other chronic wound models, such as diabetic foot ulcers (DFUs).

Introduction: Chronic wounds affect approximately six million people in the United States. Despite established multidisciplinary wound care protocols, patient adherence to follow-up care remains suboptimal. We aimed to understand the impact of social drivers of health on patient decision-making for improving wound care follow-up adherence. Methods: We conducted a retrospective review of all hospitalized patients who consulted in-house wound care staff at a tertiary care center between August 2017 and June 2020, regardless of primary admission diagnosis. Referred patients received standardized care from a multidisciplinary team at an outpatient wound care facility. Primary endpoints were pre-discharge scheduling and follow-up rates. Follow-up efficacy was assessed through 90-day hospital readmission rates. Results: Of 444 patients, 205 (46.2%) were readmitted or expired within 90 days. Adjusted analysis identified lack of follow-up care reception as an independent predictor of hospital readmission (hazard ratio 2.39; 95% CI, 1.45–3.89; p < 0.001). Among 156 (35.1%) patients who scheduled follow-up, 110 (70.5%) adhered to their appointment. Patients not scheduling follow-up were older (median age 79 vs. 70 years, p < 0.001), longer hospital stays (median 9 vs. 6 days, p < 0.0001), and more frequently discharged to skilled nursing facilities (47.6% vs. 26.3%, p < 0.0001). Among scheduled patients, skilled nursing home residents demonstrated lower follow-up adherence (OR 0.3; 95% CI, 0.14–0.65; p < 0.01). Conclusions: Pre-hospital discharge communication for scheduling follow ups serves as a critical intervention point in patient decision-making for wound follow-up. Considering the limitations of a retrospective single-center study, we find that pre-discharge education about follow-up scheduling for high-risk groups, including patients ≥ 80 years and skilled nursing facility residents, may improve follow-up adherence and reduce readmissions.
