Comparison and Evolution of Medical Care of Inpatients with Acute Myocardial Infarction in Portuguese Public Hospitals Faculdade de Medicina da Universidade do Porto
Introduction Background and Justification • Acute myocardial infarction (AMI – ICD9 410) is one of the major causes of death among Western civilization. • Such studies are not widespread among Portuguese institutions • Access to hospitals’ admnistrative data.
Value • Understandingthe general qualityconcerningthetreatmentof AMI inPortuguesePublicHospitals. • Itmaycreatetheneed for improvement. • Stimulatingfurtheranalysisandfuturestudies. • Providing a guide for general population.
Age-standardised death rates per 100,000 population from AMI, from 1972 to 2002, in Portugal
AcuteMyocardialInfarction (AMI) • Medical term for heart attack. • Caused by the blockage of the coronary arteries which will lead to an insufficient blood suply to the heart muscle (myocardium).
Research Question and Aims RESEARCH QUESTION • What is the status of medical care system in Portugal for AMI and how has it evolved throughout the years? • What is the geographical distribution of AMI incidence in mainland Portugal? AIMS • Compare different Portuguese areas according to 2 criteria • Compare hospitals’ quality based on 2 criteria. • Evaluatetheimprovementsofmedicalcareinhospitals.
SampleEvolution Total number of admissions with AMI, fatality rate and median length of stay in the hospital, per year of admission (total n= 91133)
Sample LengthofStay Fatality/Survival rate
Participants and Methods Study Design • Transversal and longitudinal Study • Data: fromallPortuguesePublicHospitals, from 2000 to 2007.
Participants and MethodsData and Variables • Variables: • Number of admissions; • Lenght of Stay; • Fatality rate: FR = Number of deaths caused by AMI Number of Admissions by AMI Extract of the database’s codes
Hospitals’ Classification • According to the newest hospital classification: • Central hospitals– Including the main hospitals of the main regions in Portugal; • Distrital hospitals– Including the main hospitals of secondary regions in Portugal; • Level 1 distrital hospitals – Including the smallest hospitals.

Evolution ---- Median length of stay ___ Fatality rate The evolution of fatality rates and median length of stay throughout the years, for central, distrital and level 1 distrital hospitals
Discussion • EVOLUTION • Regarding the fatality rate: • No significant variation was observed for distrital and central hospitals. A slight increase was observed for type 1 distrital hospitals. • These results should not be linearly associated to a decrease in the quality of medical care provided as various factors could be related to this (ex: older population). • Regarding the length of stay: • a very slight decrease was observed, more evident between the years of 2000 and 2002 and between 2004 and 2006. • This can be connected to structural and organizational modifications in SNS hospitals, like the introduction of “Hospitais SA” in 2002 and “Hospitais EPE” in 2004.
Discussion • COMPARISON • As expected, there were significant differences between the three types of hospitals. • Admittance of an association between lower fatality rate and lower length of stay. • Possible indicators in the quality of care provided.
DiscussionLimitations • Information relative to the year 2007 (some changes may have occured since). • Possible information bias in the database. • No information ab0ut procedures.
