Despite the advantages that new technologies can bring, it has been observed that these new tools can contribute to over-prescribing unnecessary medications and treatments. Currently, contempt for the physician's clinical and intellectual capacity has increased and evidence-based medicine, medical guidelines, and large randomized studies have been valued. Despite the increasing aid of technology in medicine, the number of lawsuits for medical failure has increased, with diagnostic errors and technical failures being the most recurrent causes. Clinical examination and anamnesis can never be considered inferior to complementary exams. A good history and clinical examination are still unsurpassed since when performed properly they can reduce by more than half of complementary exams. Thus, in order to avoid over-examination requirements and financial resources to be spent more efficiently and effectively, medical expenditure management should not only focus on reducing costs, but should be the basis for better distribution and use of available resources, so that greater organizational effectiveness can be achieved and this reflects in improving the quality of health care of the population.
