Randomized Controlled Trial Multicenter Study
Mechanism and prevention of facial pressure injuries: A novel emergent strategy supported by a multicenter controlled study in frontline healthcare professionals fighting COVID-19.
Numerous healthcare professionals fighting COVID-19 worldwide are suffering from the protective respirators related facial pressure injuries. This study explored the mechanism and prevention of such injuries and devised a novel emergent strategy, which was supported by a multicenter self-controlled study in 1161 frontline healthcare professionals. In this study, according to the anatomy of the face and the characteristics of facial pressure injuries, a respirator liner was designed using a polyurethane foam to redistribute the pressure across the face. ⋯ The questionnaire investigation showed that pain score, wearing disturbance, and the incidence of pressure injury in the healthcare professionals were significantly correlated with wearing time (all ρ = 0.986). The new strategy significantly reduced the incidence of pressure injury from 84.7% to 11.1%, pain score IQR from 5 (2) to 1 (2), and wearing disturbance rate from 91.6% to 6.3%, and the results analyzed according to individual hospitals or different wearing time showed similar trends (all P < .0005). The protective respirators related facial pressure injuries can be effectively mitigated with this emergent strategy, which has also been applied in some European hospitals and can be popularized to help more healthcare professionals who are combating COVID-19 on the frontlines.

Randomized Controlled Trial
Prophylactic dressings in the prevention of pressure ulcer related to the use of personal protective equipment by health professionals facing the COVID-19 pandemic: A randomized clinical trial.
Device-related pressure injury (DRPI) is a serious problem that is affecting professionals working on the front lines against COVID-19 due to the prolonged use of personal protective equipment (PPE). In addition to the physical and psychological integrity of professionals, these injuries can compromise the quality of care. Therefore, using technologies to prevent this adverse effect is an urgent matter. ⋯ There was no difference between the groups regarding skin conditions and discomfort (P > .05). The average cost obtained was $ 5.8/person and $ 4.4/person in the foam group and the hydrocolloid group, respectively, considering the dressing measurements. The results show that foam and extra-thin hydrocolloid were effective in preventing DRPI associated with the use of PPE.

Randomized Controlled Trial Multicenter Study Comparative Study
Flaminal® versus Flamazine® in the treatment of partial thickness burns: A randomized controlled trial on clinical effectiveness and scar quality (FLAM study).
Although partial thickness burns are the most frequently reported burn injuries, there is no consensus on the optimal treatment. The objective of this study was to compare the clinical effectiveness and scar quality of Flaminal® Forte to silver sulfadiazine (Flamazine®) in the treatment of partial thickness burns. In this two-arm open label multicenter randomized controlled trial, adult patients with acute partial thickness burns and an affected total body surface area of less than 30% were randomized between Flaminal® Forte and Flamazine® and followed for 12 months. ⋯ More patients in the Flaminal® group developed wound colonization (78% versus 32%, p < 0.001), but the treatment groups did not differ regarding the incidence of local infections and use of systemic antibiotics. In terms of scar quality, no statistically significant differences between both treatment groups were found regarding subjective scar assessment (Patient and Observer Scar Assessment Scale (POSAS)), scar melanin and pigmentation (DermaSpectrometer®), and scar elasticity and maximal extension (Cutometer®) during 12 month postburn. In conclusion, time to wound healing did not differ, but the use of Flaminal® Forte seemed favorable because less dressing changes are needed which lowers the burden of wound care.

Randomized Controlled Trial
Evaluation of inguinal vascular surgical scars treated with closed incisional negative pressure wound therapy using three-dimensional digital imaging-A randomized controlled trial on bilateral incisions.
Scar formation is an important, permanent surrogate marker for wound healing. The main aim of this randomized trial was to evaluate the effects of incisional negative pressure wound therapy (iNPWT) on scar formation in uncomplicated wound healing with 3-dimensional (3D) digital imaging. ⋯ The present randomized trial showed that iNPWT and standard dressings on closed transverse inguinal incisions after EVAR resulted in equal subtle scar formation. Objective scar evaluation with 3D images showed good inter-rater agreement.

Randomized Controlled Trial Multicenter Study
Long-term scar quality in burns with three distinct healing potentials: A multicenter prospective cohort study.
The laser Doppler imager is used in cases of indeterminate burn depth to accurately predict wound healing time at an early stage. The laser Doppler imager classifies burns into three estimated healing potentials as follows: high, <14 days; intermediate, 14-21 days; and low, >21 days. At this time, the relationship between these healing potentials and long-term scar quality is unknown. ⋯ Scar quality was very similar in high and intermediate healing potential wounds. No positive effects were found on scar quality or on healing time in surgically treated wounds with intermediate healing potential, advocating a conservative approach. Further studies should focus on the optimal timing of surgery in low healing potential wounds.
