Análise da informa??o em saúde: 1893-1993, cem anos da Classifica??o Internacional de Doen?as
Laurenti,Ruy;
Revista de Saúde Pública , 1991, DOI: 10.1590/S0034-89101991000600001
Abstract: the analysis of mortality by cause, as well as of morbidity, calls for an instrument that groups the diseases according to common characteristics, that is to say, a classification of diseases. the who internatinal classification of diseases, in its ninth revision, is currently in use. this classification first appeared in 1893; its tenth revision is being proposed for 1993. this present paper describes the origins of this international classification, making special references to john graunt, william farr and jacques bertillon as well as describing the evolution that has occurred through its successive revisions. initially it was a classification that included only causes of death. after the sixth revision included all the diseases and causes of medical consultations, thus allowing its use in morbidity. for the tenth and later revisions, a "family" of classifications is proposed, for a great variety of uses in health services, administration and epidemiology. some critical observations on the current international classification of diseases are also presented.
Doen?as respiratórias como causa de morte no município de S?o Paulo, SP (Brasil)
Laurenti,Ruy;
Revista de Saúde Pública , 1981, DOI: 10.1590/S0034-89101981000400001
Abstract: mortality caused by respiratory diseases in the city of s. paulo (brazil) was studied. emphasis is given to the acute respiratory infections and their relative importance as compared to chronic respiratory disease. mortality data were corrected through research by which additional information was obtained; this correction led to a comparison between the official mortality data and the corrected data. this comparison showed that official statistics, based upon death certificates, did not reflect the magnitude of the problem; that is, acute respiratory infections were overestimated and chronic, underestimated. if the same distortion occurs in other areas of the world, the relative importance of mortality from acute respiratory diseases withing the whole group of respiratory diseases does not have the magnitude stressed by other authors, especially in a study where data from 88 countries were analysed.

Laurenti,Ruy;
Revista de Saúde Pública , 1987, DOI: 10.1590/S0034-89101987000300013
Abstract: data regarding infant, early neonatal, neonatal, pos-neonatal and perinatal mortality are presented for the usa, sweden and the state of s?o paulo, brazil, for the period from 1950 to 1982. sweden, throughout the period presents the lowest rates and the state of s?o paulo the highest. the rates for the state of s?o paulo can be considered very high and the data show that at the beginning of the 80's the infant mortality was similar to that observed in sweden half a century before and the mortality under one day of life was higher than that for all the first year of life. for the three populations there is a decline in all the rates, but in sweden and the usa, although presenting the hower rates, the decline is more pronounced.

Marcos referenciais para estudos e investiga??es em mortalidade materna
Laurenti,Ruy;
Revista de Saúde Pública , 1988, DOI: 10.1590/S0034-89101988000600007
Abstract: this paper deals with some issues related to maternal mortality as a public health problem and emphasizes others that should be considered when rates are used to measure this mortality. the main questions discussed are the small number of maternal deaths, even when the related rates are elevated; the accuracy of the data; cases where maternal death is suspected; the fertile period; the concept of maternal death and the 42-day period after delivery; the denominator of the rate; the direct, indirect and non obstetric causes of death and other variables of interest.
Fatores de erros na mensura??o da mortalidade infantil
Laurenti,Ruy;
Revista de Saúde Pública , 1975, DOI: 10.1590/S0034-89101975000400008
Abstract: among the traditionally used health indices the infant mortality rate is distinguished as the most important one. frequently it is used by the public health professionals for health level characterization and for the evaluation of programmes. there are, however, several error factors that affect its value, among which are the live birth definition and its true use; underregistration of deaths and births; the death register by place of occurrence; live birth definition in the year, and the wrong age information. there are also qualitative errors due to wrong information as regards the causes of death. several of these factors were discussed for s. paulo.
A análise da mortalidade por causa básica e por causas múltiplas
Laurenti,Ruy;
Revista de Saúde Pública , 1974, DOI: 10.1590/S0034-89101974000400008
Abstract: some aspects of mortality statistics based on underlying and multiple causes of death are analysed. a sample was drawn for study from deaths ocurred in hospitals using the official death certificates. with the help of additional information taken from medical records the death certificates were filled out again and compared with the original ones showing that the basic cause of death was incorrectly stated in 37.7% of the official death certificates and that there were some counterbalancing divergences. the average number of diagnosis per official death certificate was 1.9. with additional information it went up to 2.9. the longer the evolution of the basic illness, the greater the increase of the average number of additional diagnosis accompanying the basic cause. the multiple causes of death classification allowed acknowledgement of rare causes of death that very seldomly appeared as underlying causes of death. the mortality statistics by causes are not affected by the changes in the rules of death cause selection.
O problema das doen?as cr?nicas e degenerativas e dos acidentes nas áreas urbanizadas da América Latina
Laurenti,Ruy;
Revista de Saúde Pública , 1975, DOI: 10.1590/S0034-89101975000200014
Abstract: some health problems have been enhanced by the swift urbanization that latin america cities are going through at present. chronic and degenerative diseases besides accidents, moreover those caused by traffic and occupational hazards, in these areas have shown an increasing trend as regards incidence, measured by mortality rates. cardiovascular problems and malignant tumours, among the chronic diseases, reveal at times higher mortality rates than those observed in cities of highly developed countries. the incidence of traffic accidents and those due to occupational hazards is also discussed. these too are indeed more often than what is usually observed in developed countries. these aspects are increasingly demanding more services but are a problem as regards priorities for, in latin america, infeccious diseases still contribute with very high mortality rates, on the contrary of what goes on in highly developed countries where infeccious diseases have almost been abolished. thus, for example, in the city of s. paulo although there is a great demand for services to cope with chronic and degenerative diseases and accident hazards, a considerable ammount of public expenditures is directed towards infeccious diseases.

Laurenti,Ruy;
Revista de Saúde Pública , 1969, DOI: 10.1590/S0034-89101969000200012
Abstract: infant mortality rates in latin america are high. a thorough study of its causes and different aspects in several areas would be feasible only through coordinate continental investigations such as the "inter american investigation of mortality in adults". the pan american health organization is carrying out a study named "interamerican investigation of childhood mortality", in 13 areas of latin america, to investigate deaths of children of less than 5 years of age. these deaths are studied through interviews with the families, doctors and hospitals which were in contact with the children during the period of illness that led to death. thus, data and information are obtained, with relation to the basic and related causes of death, as well as an evaluation of the nutritional state of the children. simultaneously, an investigation is made on alive children of less than five years of age, through a random sampling technique of the houses in the area of study. s?o paulo participates in this investigation through the department of applied statistics of the university of s?o paulo school of public health. the area of study includes the district of the capital, which contains 93% of the population of the entire county.
