Abstract: Store-and-forward method has contributed for telemedicine as an efficient method to the clinical diagnosis acquisition. Studies in teledermatology demonstrated important outcomes, such as the use of computer systems based in asynchronous method for long-distance diagnosis, categorization, triage, or clinical outcomes agreements. However, for some issues there is no consensus between studies, such as the image parameters or the data that must be submitted to analyze. The aim of this study is propose the development of a web system that establishing patterns to construct web asynchronous system. A prototype was constructed to test a structure (clinical data and images) to obtain clinical diagnosis concordance in teledermatology. The preliminary outcomes showed that rate clinical diagnosis is nearly when we compare face-to-face method (76.6%) and store-and-forward (70.3%). The most effectiveness occurs to some diseases, who present easy clinical diagnosis in traditional consult. We expect that this system could introduce a numerical method, established in statistical data, to construct store-and-forward system. 1 INTRODUCTION The telemedicine was developed and based under the concept of the access to health-care using information technology in situations where the long distance is a critical factor (Craig and Patterson, 2005). The Internet extended this concept under the paradigm of the widely collaboration between health professionals. Due to traditional face-to-face method consultation, using visual observation of the patient and method to obtain date to realize an initial diagnosis hypothesis, specialties such as dermatology and ophthalmology (Finamor et al., 2005) are further adjusted to these requirements, widely documented (Ferguson, 2006). Several studies based in store-and-forward teledermatology have been performed and the outcomes are: • higher concordance rates in comparison to outcomes histological diagnosis (Du Moulin et al., 2003; Moreno-Ramirez et al., 2005; Chao et al., 2003); • categorization of outcomes (Piccolo et al., 2004); • clinical case triage, according to urgency level (Oakley et al., 2006); • fast reply (80% of submitted consultations in one day) to requisitions submitted to experts using a non-commercial network based in use of easy platform to teleconsultations services (Massone, 2006); • number of patients (51%) reduction referral for the consultation with the expert, when teleconsultations (data and image) are submitted from general practioner by email, to expert. This value is similar to the real time cases (Knol et al., 2006); • similar clinical outcomes in comparison to virtual teleconsultation (Pak et al., 2007). However, there is no agreement in several issues as the influence and minimum level of images quality (resolution and compression) for a compose efficient clinical diagnosis, minimum data set to be submitted, the composition of the patients history clinical and reply, the adequate specialties to asynchronous method, the restrictions to use, the level of complexity of the clinical cases that must be diagnostics efficiently, and the influence of expert’s experience. It’s necessary to implement a structure and vocabulary to the establishment of a computation system to realize experiments that allows the 231
