Since 2007, the Government of the State of So Paulo implanted a model of known clinical attendance as IT LOVES (Ambulatory Doctors of Specialties). Intention was to offer units of attendance that had modern equipment, as eletrocardiograma, electro-encefalograma, ergometric test, ray-x, ultrassom, mamografia, ssea densitometria and eletroneuromiografia, and that they could go facilitating and speeding the attendance of hospitals that are overloaded. This bigger rapidity happens IT LOVES because it makes possible that the patients pass, in the same date, for consultations and examinations, being that until the return with the doctor it can happen the same in day. Therefore, to congregate and to integrate all the ambulatoriais consultations, services, examinations and surgeries in an only system of information became essential for the functioning of these ambulatory ones. Joining the pioneirismo in invoicing SUS with the experience in the requirements of the invoicing of accounts, the Wareline, company specialized in development of systems of hospital computerization, it offers to AMEs a tool complete, capable to take care of the specific characteristics of this new modality of service created for the Government of the State. Its system registers all the information in an only handbook of the patient, giving subsidy for the remain of the attendance (guiding for surgery or other forms of treatment). The Wareline system also offers rastreabilidade and generates the cost of each taken care of patient, counts that it must obligatorily be presented the Government before the money view is carried through monthly. Another functionality is that, beyond obtaining to select this cost of each attendance carried through in the unit IT LOVES of it, the system also obtains to evaluate the hospital cost of all the unit. Currently, 26% of the AMEs of the State of So Paulo already use the System of Wareline Information, with prominence for the attendance of the units of Atibaia, Jump and Are Jose of the Black River.
