Abstract in Portuguese
Anualmente são realizadas mais de 234 milhões de cirurgias no mundo com taxas de morbi e mortalidade relativamente elevadas. Os dados nacionais disponíveis de registros de operações não cardíacas são escassos e deficientes. O objetivo do nosso estudo foi avaliar o perfil epidemiológico dos pacientes submetidos a operações não cardíacas e a sua evolução nos últimos anos no Brasil. Selecionamos a partir do banco de dados de DATASUS, as informações de sistema público de saúde em caráter nacional para descrição epidemiológica de operações não cardíacas realizadas no país. As variáveis estudadas foram: número total de internações, gasto total por internação, gasto com transfusões sanguíneas, número de óbitos e tempo de internação hospitalar. O período estudado compreendeu os anos de 1995 a 2007. No período de 13 anos, foram realizadas 32.659.513 operações não cardíacas no país e houve um incremento de 20,42% no número de procedimentos realizados. De forma semelhante, os gastos hospitalares relacionados a estas cirurgias apresentaram aumento importante neste período (~ 200%), com gasto anual superior a 2 bilhões de reais. As despesas relacionadas às transfusões sanguíneas no perioperatório tiveram um aumento superior a 100%, com um gasto anual acima de 17 milhões de reais ao ano. A mortalidade hospitalar encontrada é bastante elevada no nosso país, com média de 1,77% e o aumento registrado foi mais de 30% no período. A única variável que apresentou redução ao longo dos últimos anos foi o tempo de internação hospitalar, com a média de permanência de 3,83 dias. Concluímos que há uma tendência no aumento de intervenções cirúrgicas no país. Apesar do aumento dos gastos hospitalares relacionados a estas cirurgias, a taxa de mortalidade encontrada ainda é bastante elevada. Estudos futuros são necessários para maior investigação e elaboração de estratégias complementares para melhorar os resultados cirúrgicos

Abstract in English
Worldwide, there were performed about 234 millions of surgeries annually with a relatively high surgical morbidity and mortality. Registry and information about non-cardiac operations in Brazil are scarce and deficient. The purpose of our study was to describe the epidemiological data of non-cardiac surgeries performed in Brazil in the last years. This is a retrospective cohort study that investigated the time-window from 1995 to 2007. We collected information from DATASUS, a national public health system database. The variables studied were: number of surgeries, in-hospital expenses, blood transfusion related costs, length of stay and case fatality rates. There were 32.659.513 non-cardiac surgeries performed in Brazil in thirteen years. An increment of 20.42% was observed in the number of surgeries in this period. The cost of these procedures has increased tremendously in the last years. The increment of surgical cost was almost 200% and the yearly cost of surgical procedures to public health system was superior to 1.2 billions of dollars (2 billions of reais). The cost of blood transfusion had an increment superior to 100% and annually approximately 10 millions of dollars (17 millions of reais) were spent in perioperative transfusion. Actually, in 2007, the surgical mortality in Brazil was 1.77% and it had an increment of 31.11% in the period of 1995 to 2007. The length of stay was the unique variable which had a reduction of its numbers in the period. In average, the mean time of surgical hospitalization was 3.83 days. We concluded that the volume of surgical procedures has increased substantially in Brazil through the past years. The expenditure related to these procedures and its mortality has also increased as the number of operations. Better planning of public health resource and strategies of investment are needed to supply the crescent demand of surgery in Brazil
