CLASIFICACIÓN DE LAS VENAS PERIFÉRICAS SUPERFICIALES EN ADOLESCENTES, ADULTOS Y ANCIANOS MEDIANTE LA TÉCNICA DELPHIThe process of developing and using a classification is not new to the profession; these classifications contribute to the establishment of a common language, providing comparable data or defining a precise denomination for a fact or event, whether in teaching, research or care.A classification needs to reflect its purpose, its conceptual domain; it needs to be logical, clear, relevant and useful. This process involves continuous development and refinement (8)(9) . Hence, this study is relevant to enable an agreement about peripheral puncture vein types through language standardization among nursing professionals. , so as to assure the same or a higher number of specialists when compared to the possibilities for the five levels that constituted the Likert scale we used. Therefore, the sample consisted of 35 participants: 14 nurses, seven angiologists, seven anesthetists and seven biochemists. A 90% agreement level was adopted for this phase to guarantee reliability.
OBJECTIVEIn the preliminary version, the instrument presented the different types of designations for the veins (definitions and titles), formatted according to a fivepoint Likert scale (11)(12)(13)(14)(15)(16) (1 = completely irrelevant/ inadequate; 2 = moderately irrelevant/inadequate; 3 = relevance/adequacy level similar to irrelevance/ or the use of indicated or self determined medicine a n d / o r i t s u n d e s i r a b l e e f f e c t s ( p u n c t u r e s , transfixions). Thus, they do not present inspection, palpation or measurement detectable evidences of content extravasation, nor is it possible to identify
