“…For instance, area measurement with planimetry was used in a phase IIa study of topical tofacitinib in the treatment of chronic plaque psoriasis, referred to as target plaque area . Transparency tracing and planimetry have also been employed in research involving localized scleroderma, vitiligo and burn wounds . Our results support the reliability of computerized planimetry as a tool to assess the area of DLE lesions, with excellent reliability found within raters, between raters and between computers.…”

“…Subjective assessment has often been used in the past in wound healing studies . Wounds can be assessed by simple tracings and ruler‐based measurements or by technological methods, such as digital image analysis, computerized planimetry, and three‐dimensional laser . The RCTs reviewed in Table generally used more technological methods, such as computerized planimetry for assessment, with a few trials using subjective assessment.…”

We investigate how wound closure is determined in recent randomized controlled wound trials and real-world studies, identify solutions to the current limitations of wound assessment, and propose a standard methodology to define and assess wound healing in research. We searched PubMed for randomized clinical trials using the terms "complete wound closure" and "wound healing rate" and for real-world studies using the terms "real-world wound healing," "real-world wound data," and "wound registries" dating from March 2010 through March 2018. We selected studies that had "complete wound closure" or "healed wound" as an endpoint. Sixty-five trial articles and 10 real-world articles met our criteria, from which we extracted the wound type studied, definition of healed wound used, wound assessment method, the number of weeks assessed, the number of wounds, and the percent of healed wounds in the study group(s) and control group. There were 7,194 trial wounds included. The most common definition of healing used by 26 studies (40.6%) was complete/full/100% (re)epithelialization or closure without discharge, drainage/scab, and/or dressing. Fiftytwo studies (81.2%) used blinded wound assessment, and at least 10 studies (15.6%) used blinded adjudication. The real-world studies analyzed more than 901,396 wounds. Only three studies (33.3%) defined a healed/closed wound, two of which used "complete epithelialization." Eight studies (88.9%) did not define the wound assessment method; none indicated a blinded assessment. We support the Food and Drug Administration definition: 100% reepithelialization of the wound surface with no discernable exudate and without drainage or dressing, confirmed at two visits 2 weeks apart, and we recommend blinded adjudication for wound assessment. The widespread adoption of a standard wound healing definition and assessment method in wound care research would allow for stronger comparisons of treatment effects across studies to improve the evidence base and strengthen the treatment decisionmaking process in clinical practice.

“…Classical and routinely used visual observation of the wound site is a subjective method, requires an expert clinician to infer and can often lead to the bias . Slight advancement in this method with image capturing of the wound, following ruler‐based measurement or computerized planimetry and digital image analysis , has also been reported earlier. Nevertheless, difficulty in color calibration and recognizing exact wound margin are the major drawbacks associated with the above methods restricting their use in case of complex wounds .…”

The focus of the current study was to interrogate the predictive potential of laser-induced autofluorescence (LIAF) by objectively assessing collagen synthesis in burn wound granulation tissues ex vivo. Prior grafting, granulation tissues (20 samples) following burn injury were collected from 17 subjects of age range 18 to 60 years with patient/donor consent and the corresponding autofluorescence spectra were recorded at 325 nm He-Cd laser (≈2 mW) excitations. The resulting endogenous collagen intensity from the above tissue samples was computed by normalizing the nicotinamide adenine dinucleotide levels. In addition, the hydroxyproline content was also estimated biochemically from the same granulation tissues. A comparative assessment of both LIAF and biochemical estimations for endogenous collagen by hydroxyproline resulted in strong positive correlation among them. The above relevant observations suggest that LIAF is equally informative as that of biochemical estimations, in evaluating endogenous collagen content in wound granulation tissues. Thus, it can be concluded that LIAF has the predictive potential, as a noninvasive objective tool to measure the endogenous collagen levels in wound biopsy tissues and provide complementary data conducive for making clinical decisions.
