INTRODUCTION
Caring for patients with chronic wounds has been a major challenge in nursing clinical practice; resulting in high rates of morbidity and a significant impairment of quality of life. 1 These injuries affect a large portion of the world's population, generating high costs for public health in many countries. 2 Wound assessment is one of the basic stages for care planning in all healthcare levels: ambulatory, home or hospital. International guidelines for wound treatment recommend a minimum of weekly evaluation, using a standardized instrument that enables monitoring of the healing process. However, there is not yet consensus on the best way to evaluate the wound and its healing process. [3][4][5] The international literature offers instruments for evaluating wounds, including the: Pressure Sore Status Tool (PSST), 6 Pressure Ulcer Scale for Healing (PUSH), 7 Wound Healing Scale (WHS), 8 Sussman Wound Healing Tool (SWHT), 9 and Bates-Jensen Wound Assessment Tool (BWAT). 10 These instruments are validated, reliable, aid clinical practice, and can be used as decision tools by nurses for patient care. 1 Among the available instruments, the Pressure Sore Status Tool (PSST), developed in 1990, using the Delphi technique; aims to monitor the healing process of pressure ulcers. In 2001, the instrument was reformulated in order to be used for other wounds etiologies, and was renamed the Bates-Jensen Wound Assessment Tool (BWAT). 3 The current version of the BWAT contains 13 items assessing size, depth, edges, undermining, type and amount of necrotic tissue, type and amount of exudate, peripheral tissue edema and induration, skin color surrounding wound, granulation tissue, and epithelialization. The measuring scale is a five point Likert types, where 1 indicates the best condition of the wound and 5, the worst condition. The total score is obtained as the sum of all the items, and can range from 13 to 65 points, with higher scores indicating the worst wound conditions. Items such as size, depth, edges and detachment should be scored as zero when the lesions are healed. The instrument contains two additional items -location and shape -which are not part of the total score. 10 In its original format, a guide accompanies the BWAT with instructions for completion of each assessment of the wound items. This guide enables professionals to use the same criteria during the evaluation process, as it defines each characteristic to be observed. The BWAT has satisfactory validity and reliability indices, with a Cronbach's alpha of 0.90, sensitivity of 61%, specificity of 52%, and a positive predictive value of 65%. 10 Considering the recommendations from the main international consensus that guide the assessment of wound conditions through a reliable method, and the difficulty of nurses in clinical practice to assess and monitor the healing process of chronic wounds, this study aims to translate and adapt the Bates-Jensen Wound Assessment Tool instrument for the Brazilian culture, and to assess its feasibility.

METHOD
This was a methodological study, characterized by translation and adaptation of the BWAT to Brazilian culture, conducted after authorization from Bates-Jensen, the author of the original instrument.
The instrument and the completion guide were submitted for translation and a cultural adaptation procedure, in accordance with international recommendations, 11-12 using the steps: translation, synthesis, back translation, evaluation by a committee of experts, and testing of the translated version. The purpose of these steps was to ensure the quality of the adapted instrument and its equivalence with the original instrument.
Two independent translators, a nurse and a language teacher, fluent in English and having Portuguese as their first language, performed the first BWAT translation; only the language teacher was informed of the study objectives. A third translator, fluent in the instrument's source language, which produced the synthesis version of the instrument, assessed the first two translations.
In the third step, the translation synthesis was sent to two other translators, a nurse and a language teacher who were fluent in the target language (Portuguese), with English as their first language, to produce back-translations. The purpose of this step was to evaluate discrepancies between the original and the translated instrument.
The equivalence between the original and the translated BWAT versions was evaluated by a committee of five experts: a teacher with experience in the methodological process of translation and adaptation of instruments, a teacher with experience in caring for patients with wounds; two nurses and one generalist stomatherapy nurse. Committee members were invited to review the synthesis version according to its equivalence with the original version, indicating their agreement to each item and modifications necessary to adjust the item. For this procedure, experts received written guidance and a tool specifically developed for this analysis, also containing the original instrument and all versions produced.
The equivalence assessment was performed in a quantitative manner by individual responses of each of experts, for each of the items. The interrater agreement (IRR) was determined, expressed in percentage, calculated by: (number of experts who agreed with the item/number of experts) x100. The items were appropriate when the IRR was less than 80%. 13 Items with an IRR lower than 80% were modified in accordance with the committee's suggestions. The translated instrument was obtained after these steps, and named the

BWAT Brazilian version
The translated version of the BWAT was tested by nurses in adult and intensive care patients of a teaching hospital in São Paulo state. Generalist nurses and specialists with professional experience of more than five years integrating patients with wounds within their institutional commission were invited.
For assessment of the translated instrument, nurses received a sociodemographic characterization form, the modified Feasibility Assessment Tool, and the translated version of the BWAT Brazilian version. The sociodemographic form consisted of seven items: unit, age, sex, length of experience as a nurse in the institution and sector, and nurse education.
The practicality of the BWAT Brazilian version was assessed using a modified Feasibility Assessment Tool. 14 This instrument contains four items assessing the ease of understanding the instructions, items, completing the answers, and the interest in having a tool in clinical practice for evaluation of chronic wounds. All questions were evaluated using a five point Likert response scale: 1-strongly disagree, 2-partially disagree, 3-I have no opinion, 4-partially agree and 5-strongly agree. The analysis of responses was obtained by the percentage of response of participants for each of the items. The higher percentage of responses of "partially agree" and "agree", the greater the instrument feasibility. The BWAT Brazilian version modifications suggestions for the translated version were analyzed by the authors.

RESULTS
The translation and adaptation of the BWAT for the Brazilian culture followed the steps of translation, synthesis, back translation and testing of translated version. Translators did not report difficulties in producing versions of the instrument and completion guide.
Because 13 items achieved an IRR below 80%, a consensus reunion among experts was not necessary, as suggested modifications were specific and related to order and agreement between words. By consensus, the authors adjusted and formulated the final BWAT version according to suggestions of the experts. The words of the instrument that generated discrepancies between experts were modified with technical adequacy to the term of the English language, with semantic equivalence in respect to the original instrument in English. All experts agreed to maintain the layout and the original instrument name -Bates-Jensen Wound Assessment Tool (BWAT) -plus the term "Brazilian version", to facilitate international scientific access. The characteristics of the 28 participants in the testing of the translated version are shown in Table 1. Nurses who participated in the evaluation of the BWAT Brazilian version assessed the comprehension of items and the instrument completion guide. Participants reported difficulties with: completion of the shape, the location of the wound, mark on the body chart, the anatomical location of the lesion, and score wound status continuum. They also indicated the substitution of some terms and standardization of nomenclature, for example, replacing the term "round" with "circular".
Regarding feasibility, the BWAT Brazilian version had adequate feasibility according to the nurses, with most of answers of the four evaluation items marked as "partially agree" or "strongly agree" (Table 2). After testing the translated version, the original instrument author was consulted for changes in the items location, shape and the body chart. All the nurses and authors suggestions were accepted by Dr. Bates-Jensen and incorporated into the translated instrument. After items modification, instructions to mark the body chart and wound status continuum, the BWAT advanced version was produced, translated and adapted to the Brazilian culture (Annex 1).

DISCUSSION
Accurate assessment of a chronic wound is essential for identification of conditions and ap-propriate decisions regarding topical treatment. 10,15 The use of validated and reliable instruments enables proper documentation and therapeutic indication, 1,10 providing information exchange in the scientific community, and comparison of results in different countries. 12 These instruments, when properly used, support intervention and treatment effectiveness. 12 The BWAT was translated and proved to be a valid method for chronic wound assessment. 10 Steps of instrument translation and adaptation were satisfactory and resulted in the BWAT Brazilian version, after adaptation to the Portuguese culture and language, as recommended in the literature for instruments developed in other languages and / or cultures. 16 Replacement of terms and nomenclature standardization was performed, incorporating the author of original article in decisions regarding modification of the translated instrument.
Regarding the completion guide, agreement rates lower than 80% in eight items were found, determining specific changes suggested in the order and concordance of words. Studies show that an expert committee can modify guidelines and instrument format, changing and adding new items, 12 and that agreement rates lower than 80% are relevant, determining changes in the instrument. 13 The literature recommends that, for equivalency between the original and translated version, the expert committee should be composed of professionals with methodological experience in health and linguistics, who should evaluate the instrument according to the semantic, conceptual and idiomatic equivalences. 11 This research followed all recommended steps in the literature, and modifications suggested by experts were punctual and accepted.
There are few reliable and valid instruments for assessing chronic wounds in Brazil, and instrument incorporation for this purpose facilitates decision making by nurses about treatment and follow up of patients with wound in clinical practice. 4,15

CONCLUSION
The Bates-Jensen Wound Assessment Tool instrument was successfully translated and adapted to the Brazilian culture, following the literature recommendations, with good feasibility for use in clinical practice and research. Studies to verify validity and reliability of the BWAT Brazilian version are recommended.
