Development of International Outcomes Instrument for Hand and Upper Extremity Burn Scar Contracture Release

Abstract

Burn scar contractures remain a common source of severe disability in resource-limited countries. However, existing outcome measurements are unable to fully capture the impact of the scar contracture and surgical attempts at correction. To that end, we have developed a new outcome instrument, the Stanford-ReSurge Burn Scar Contracture Scale-Upper Extremity that can be used as a measurement of disability and reconstructive procedure outcomes. The outcome instrument was created through item generation, item reduction, and preliminary field testing. We performed a literature review using multiple databases to gather a comprehensive list of existing burn contracture metrics, removed metrics that were inapplicable in resource-limited settings, and submitted remaining items to plastic and hand surgeons for evaluation of clinical and cultural relevance, comprehensiveness, and feasibility. The remaining items were field tested to evaluate patient comprehension and ability to detect change over 1 month. A literature review found 32 unique scales that were eventually reduced to a pool of 38 potential items that were field tested with patients. Patient feedback further reduced the item pool to the final 20-item scale. Patients who underwent burn scar contracture release of the upper extremity showed an average of 14 points improvement between the preoperative and 1-month postoperative time point. The Stanford-ReSurge Burn Scar Contracture showed clinical utility for assessing outcomes in burn scar contracture release of the upper extremity. Our goal is to develop a standardized outcome instrument for burn reconstruction in the world's poorest burn patients.

Subjective Tools for Burn Scar Assessment: An Integrative Review

“…Patient and Observer Scar Assessment Scale (POSAS) [22][23][24][25][26][28][29][30][31][32][33][34][35][36][37][38][39][40]42,51,63, Evaluate the appearance of the scar and assign a weight to the patient's opinion regarding the scale dimensions Vascularization, pigmentation, thickness, relief, malleability, surface area, pain, itching, color, stiffness, height, and irregularity Modified POSAS 53,106 Evaluate the quality and appearance of the scar and its impact on daily life Vascularization, pigmentation, thickness, relief, malleability, surface area, pain, itching, color, stiffness, height, irregularity, restriction, psychological stress, and general evaluation of the scar by the patient Vancouver Scar Scale (VSS) 9,23,28,45,46,48,[50][51][52][53][55][56][57][58][59]62,[64][65][66][73][74][75]…”

Die Verbrannte Hand – Neuheiten und aktuelle Forschung

“…Aus diesem Grund betonen Angehörige der Gesundheitsberufe nun die klinische Relevanz von Beurteilungen, die subjektive Messgrößen aus Patientensicht beinhalten [91,93,94]. Cai et al haben kürzlich ein neues Instrument für die Bewertung von Verbrennungen der Hand und der oberen Extremität präsentiert [95]. Dabei können sowohl der Grad der Behinderung durch Kontrakturen oder Deformitäten als auch der Erfolg von rekonstruktiven Eingriffen bewertet werden.…”
