Background: Expenses with coronary artery bypass grafting (CABG) surgery and coronary angioplasty (CA) represented a significant cost to SUS., Objective: To analyze SUS expenses with CABG and CA and their performance in hospitals in the state of Rio de Janeiro (SRJ), from 1999 to 2008., Methods: The information came from paid HAA in hospitals with more than 100 revascularization procedures. Mortality rates were adjusted by Poisson (with covariates age, length of hospital stay and ICU expenses). Mean relative cost indices were calculated by dividing the mean value of the cost fraction spent in each hospital by the mean expense in the SRJ in U.S. dollars. Stata software was used for statistical analysis., Results: A total of 10,983 CABG and 19,661 CA were paid by SUS in 20 hospitals during the 10 years, with mean values of US$ 3,088.12 and 2,183.93, respectively. The mortality rate in CABG varied from 9.2%-1999 to 7.7%-2008, with ranges of 5.0%-9.2% and in CA, from 1.6%-1999 to 1.5%-2008, with ranges of 0.9%-2.3%. The hospitals decreased the number of CABG procedures and doubled CA procedures. Age, time of hospital stay and ICU costs significantly correlated with lethality in CABG and CA paid by SUS in the SRJ. On average, hospital service costs represented 41% of the total cost of CABG and 18% of CA, and with ortheses and prostheses, 55% in CA and 28% in CABG., Conclusion: It is clear the need to improve the quality of healthcare service in institutions that perform CABG and CA paid by SUS.

Objective: To estimate in-hospital mortality and prevalence of complications of percutaneous transluminal coronary angioplasty (PTCA) in public hospitals., Methods: Data for 2,913 PTCA were obtained from the Brazilian National Health System (SUS) Hospital Authorization Database in the city of Rio de Janeiro, Southeastern Brazil, between 1999 and 2003. After simple random sampling and data weighting, 529 medical records of patients undergoing PTCA, including all deaths, in four public hospitals (federal and state university, and federal and state reference hospitals) were studied. Comparison tests of mortality according to patient characteristics, comorbidities, complications, types of PTCA procedures, and indications for PTCA were performed using Poisson's regression models., Results: The overall in-hospital mortality was 1.6% (range: 0.9-6.8%). The age distribution of mortality was as follows: 0.2% in patients younger than 50; 1.6% in those 50-69; and 2.7% in those older than 69. High mortality was seen in primary and rescue PTCAs: 17.4% and 13.1%, respectively; and mortality in elective PTCA was 0.8%. The main complications during PTCA were dissection (5%; mortality: 11.5%) and artery occlusion (2.6%; mortality: 21.8%). Bleeding was seen in 5.9% of the patients (mortality: 5.6%) and 3.0% required blood transfusion (mortality: 12.0%). The complication of acute myocardial infarction was seen in 1.1% of patients (mortality: 38%) and stroke was associated with a mortality of 17.5%., Conclusions: The cardiac in-hospital mortality was high when PTCA was performed for a patient with ST elevation acute myocardial infarction. Elective PTCA had mortality and complications levels above the expected in four public hospitals in the main city of Rio de Janeiro.

This study analyzes hospital case fatality associated with percutaneous transluminal coronary angioplasties (PTCA) covered by the Brazilian Unified National Health System (SUS) and performed in hospitals in the State of Rio de Janeiro from 1999 to 2003. PTCA data were obtained from the State Health Department's database on Authorizations for Hospital Admissions. Case fatality rates were estimated according to age, gender, diagnosis, and hospital. Overall case fatality was 1.9% in 8,735 PTCAs. The lowest rate was associated with angina (0.8%) and the highest rates with acute myocardial infarction (6%) and other diagnoses (7%). In the 50-69-year bracket, case fatality was higher in women. In the over-70 group, it was almost three times that of the youngest group (4% versus 1.4%). There was great variability among PTCA case fatality rates in different hospitals (from 0 to 6.5%). Ongoing monitoring of PTCAs is thus necessary in clinical practice. In conclusion, PTCA performance was still unsatisfactory under the Unified National Health System.

Objective: To estimate the lethality rate of acute and chronic ischemic heart disease (IHD) procedures, coronary artery bypass graft (CABG) procedures and percutaneous transluminal coronary angioplasty (PTCA) procedures in the hospitals that are registered as service providers for the Hospital Information System/Single Healthcare System (SIH/SUS) plan in the state of Rio de Janeiro (RJ) between 1999 and 2003., Methods: The procedures considered as CABGs and PTCAs were provided by Datasus (SUS databank). The rates were standardized in accordance with gender, age, and disease severity. The common factors among these procedures are that they are highly complex cardiovascular procedures performed in RJ in the year 2000. The IHD groups are: angina, acute myocardial infarction, other acute IHDs and chronic IHDs., Results: Lethality rates for angina, acute myocardial infarction (AMI), other acute and chronic IHDs were 2.8%, 16.2%, 2.9% and 3.9%, respectively, in the RJ. The lethality rates for CABG and PTCA, adjusted by age, sex and diagnostic groups, were elevated ranging from 1.9% to 12.8% for CABG procedures and as high as 3.2% for PTCA. When medical therapy was performed the rates were 2.3% for CABG and 11.1% for PTCA., Conclusion: There has been a progressive increase in the number of CABG and PTCA procedures to treat IHDs in the RJ. Lethality rates were above the desirable level, mainly for chronic IHD hospital admissions (5.4% and 1.7%, respectively). Optimized medical therapy appears to be a worthwhile therapeutic option, reserving CABG and PTCA procedures for the cases with the worst prognoses. Lethality rates for AMI with medical therapy was comparable to current rates when thrombolytics were not used (16.7%).
