چکیده
Objective: to compare the measurement area of venous ulcers using AutoCAD(r) and Image Tool software. Method: this was an assessment of reproducibility tests conducted in a angiology clinic of a university hospital. Data were collected from 21 patients with venous ulcers, in the period from March to July of 2015, using a collection form and photograph of wounds. Five nurses (evaluators) of the hospital skin wound study group participated. The wounds were measured using both software programs. Data were analyzed using intraclass correlation coefficient, concordance correlation coefficient and Bland-Altman analysis. The study met the ethical aspects in accordance with current legislation. Results: the size of ulcers varied widely, however, without significant difference between the measurements; an excellent intraclass and concordance correlation was found between both software programs, which seem to be more accurate when measuring a wound area >10 cm². Conclusion: the use of both software programs is appropriate for measurement of venous ulcers, appearing to be more accurate when used to measure a wound area > 10 cm². Objetivo: comparar a mensuração de área de úlceras venosas por meio dos softwares AutoCAD(r) e Image Tool. Método: trata-se de um estudo de avaliação de reprodutibilidade de testes, realizado em um ambulatório de angiologia de um hospital universitário. Os dados foram coletados de 21 pacientes com úlceras venosas, no período de março a julho de 2015, por meio de formulário de coleta e fotografia das feridas. Cinco enfermeiros (avaliadores) do Grupo de Estudos de Lesões de Pele do hospital participaram da pesquisa. As feridas foram mensuradas em ambos os softwares. Os dados foram analisados por meio do Coeficiente de correlação intraclasse, Coeficiente de correlação de concordância e procedimento de Bland e Altman. A pesquisa respeitou os aspectos éticos de acordo com a legislação vigente. Resultados: os tamanhos das úlceras apresentaram grande amplitude, porém, sem diferença significativa entre as mensurações, existe excelente correlação intraclasse e de concordância entre os softwares, os quais parecem ser mais precisos na mensuração de feridas com área > 10 cm². Conclusão: o uso de ambos os softwares é indicado para a mensuração de úlceras venosas, parecendo ser mais precisos quando utilizados para mensurar feridas com área > 10 cm².

BACKGROUND Tracking wound size is an essential part of treatment. Because a wound's initial size may affect apparent healing rates, its surface area (S) and its surface area-to-perimeter (S/P) ratio are useful to document healing. Assessments of these parameters can be made by computerized planimetry of digital images using suitable software. OBJECTIVE Because different caregivers often evalu...
