ABSTRACT

OBJECTIVE: To supplement the information on the underlying cause of death due to external causes through using news carried in newspapers.
METHODS: This study investigated 153 deaths due to external causes among people living in Belo Horizonte, Southeastern Brazil, in 2008. A database named "press" was constructed using information from large-circulation national and state-level newspapers, and this was correlated with the database of the Brazilian mortality information system. The data were analyzed using the EpiInfo and Link-plus software. The concordance of the results was assessed using the kappa coefficient.
RESULTS: A total of 1,530 news items on accidents and violence were located, and 201 of these items were matched with death certificates in the mortality information system; 153 items referred to people living in Belo Horizonte. The main causes of death identified in the databases were aggression and traffic accidents. In the press database, aggression and traffic accidents accounted for 86.3%, other accidents 7.8%, events of undetermined intent 4.6% and legal intervention cases 1.3%. After supplementation using the press database, there were increases in the numbers of deaths due to car accidents (220.0%) and motorcycle accidents (100.0%), which resulted in a decrease in the numbers of deaths due to indeterminate causes and unspecified traffic accidents notified in the mortality information system.
CONCLUSIONS: News in newspapers has great potential for qualifying and supplementing the information on the underlying cause of death due to external causes in the mortality information system, particularly regarding deaths due to traffic accidents.

INTRODUCTION

The impact generated by accidents and violence on the health of populations in Brazil and most other countries is known mainly through analysis on mortality data.10 External causes accounted for 13.6% of the deaths that occurred in Brazil in 2008, according to data from the Interagency Health Information Network.ª Although interiorization of violence is observed throughout Brazil, the proportion of mortality due to external causes continues to be higher in state capitals than in other cities in this country.15

The elevation and magnitude of the coefficients of aggression and traffic accidents in increasing young populations are striking characteristics of the Brazilian epidemiological pattern of mortality due to external causes. The rates are extraordinarily higher among adolescents and young adults, especially among males aged 15 to 29 years, than in the whole population.15

The cause of death is one of the most important items of information on death certificates, and this is fundamental for ascertaining the state of health of populations. In cases of violent or unnatural death, the death certificate, including the cause of death, should be furnished and filled out by the medical examiner service, as determined by the Brazilian penal codeb and guaranteed by Resolution nº 1601/00 of the Federal Medical Council.c When the cause of death is an injury with an external cause, the circumstance relating to the morbid event should be mentioned and selected as the underlying cause of death. The medical examiner often only mentions the nature of the injuries and does not make the circumstance of the death explicit.7 To fill this gap, the Medical Examination Institute (Instituto de Medicina Legal, IML) of Belo Horizonte, Southeastern Brazil, has been conducting systematic active searches of the information on the circumstances of deaths due to external causes, since 2000. The information sources used have been medical reports on bodies sent to the Institute, reports from other professionals and requests for expert opinions and medical expert reports. However, these sources are insufficient to adequately qualify the information on the circumstances of deaths due to external sources, i.e. accidents and violence.2,6,8,12,14 Because of this, deaths due to events in which the nature was indeterminate account for 10.1% of the deaths in this municipality, which was slightly higher than the Brazilian average of 8.7% in 2007.5 The quality of the analyses on mortality data is compromised when a considerable proportion of the causes of death are classified as events of indeterminate cause.11,12 Some Brazilian regions use news on accidents and violence published in large-circulation newspapers as complementary sources of information on the circumstances of the deaths.5 Information generated through news carried in newspapers is routinely compared with the information in the Mortality Information System (MIS) in the state of Rio de Janeiro and, in some cases, is incorporated into its database.9

The aim of the present study was to complement the information on causes of death due to external causes through using news carried in newspapers.

 

METHODS

This study investigated deaths due to external causes among large-circulation newspapers in Minas Gerais during the year 2008.

An active search for all cases of accidents and violence, independent of whether these resulted in death, was conducted by reading the news carried in three state newspapers ("Estado de Minas", "O Tempo" and "Hoje em Dia") and one national newspaper ("Folha de S. Paulo") every day. These sources were chosen because of their large circulation and potential coverage of such events. Each news item selected was logged in a data gathering tool named the "urgency and emergency notification file", which was used in a survey on accidents and violence in Belo Horizonte in 2007, as standardized by the Ministry of Health.d

The data recorded were the name, age, date of notification, date and place of occurrence (municipality, district and street address), nature (accident, violence or unknown), type of occurrence and nature of the injury. The data were input to a database name "press", which was developed within EpiInfo 2000, version 3.5.1. The circumstances of the death were obtained by means of a routine active search in the IML when necessary, followed by coding, done by technicians who were trained by the Brazilian Disease Classification Center.

The probabilistic relationship (linkage) between the press database and the MIS database was ascertained using the Link-Plus software, version 2.0. The variables used in this were the name, age, sex and date of death. Six groups were defined to assess the concordance between the causes of death obtained from each source, using the three-digit codes of the International Statistical Classification of Diseases and Health-related Problems, Tenth Revision (ICD-10):13 AGRES (aggression: X85 to Y09): ATRANSP (traffic accidents: V01 to V99): AUTO (self-inflicted: X60 to X84); INTIND (indeterminate nature: Y10 to Y34); OUTRO-AC (other accidents: W00 to X59); and LEGAL (legal intervention: Y35 to Y36). The pairs that presented 95% concordance between the pairing variables were considered to be true.

The newspaper news qualified the information from the MIS in cases of non-concordance between the causes of death in the databases, when the newspaper news provided better specification of the circumstances of the death, such as the place of occurrence, the type of weapon used, the type of accident (traffic, not traffic or not specified), the means of transportation (pedestrian, bicycle, motorcycle, tricycle, car, light truck, heavy truck, bus, other means of ground transportation, transportation on water, air transportation or space transportation) and the status of the victim (driver or passenger).

The Epidat 3.1 software was used to calculate the coefficient of concordance and whether the change in the underlying cause after investigation in the newspapers was significant. The statistical kappa coefficient was used to evaluate the concordance between the databases. Kappa measures the interobserver concordance and the degree of concordance above what would be expected by chance. Its maximum value is 1, representing total concordance, while values close to or below 0 indicate complete lack of concordance, or that the concordance was exactly what would be expected by chance. Thus, the latter values represented discordance, but without interpretation as intensity of discordance.4

This study was approved by the Research Ethics Committees of the Federal University of Minas Gerais (nº ETIC 638/08, on December 17, 2008) and of the Municipal Health Department of Belo Horizonte (nº CAAE 065.2008, on December 18, 2008).

 

RESULTS

According to data from the MIS, 1,853 deaths due to external causes occurred among people living in Belo Horizonte in 2008 (13.1% of the total number of deaths).

Among these, 1,530 deaths due to accidents and violence were identified; 13.1% were matched to death certificates, of which 76.1% occurred in Belo Horizonte. The remainder occurred in other municipalities in the state of Minas Gerais, or in other states.

Aggression and traffic accidents represented 79.0% of the deaths in the MIS (Figure 1). The events of indeterminate nature and the other accidents, such as suffocation, crushing, drowning, poisoning, intoxication and shock, among others, represented the remainder of these deaths. Aggression and traffic accidents were responsible for 86.3% of the deaths in the press database. Other accidents presented a greater number of deaths (7.8%) than shown by the events of indeterminate nature (4.6%). It should be noted that in the MIS database, none of the deaths were registered as legal interventions, but in the press database, 1.3% of the deaths were identified as this underlying cause. There was no matching of any self-inflicted death (suicide). The kappa coefficient was 0.80, thus indicating that there was significant concordance among all the causes of violent death in the two databases.

Differences were observed after investigating the concordance of the groupings according to aggression and other accidents (Table 1). Out of the 18 deaths of indeterminate nature in the MIS, the information on 12 of them was qualified after investigation: half of them were reclassified as aggression, around 42.0% as traffic accidents and 8.0% as legal intervention. It should be noted that out of these 18 deaths, 33.3% continued to be events of indeterminate nature.

There was moderate concordance between the databases (kappa = 0.41). There was an increase of 220.0% in the number of deaths involving cars and 100% in the number of accidents with motorcycles and bicycles (Figure 2). The 16 deaths attributed to individuals suffering injuries in accidents with unspecified vehicles (code V89.9) in the MIS could be identified from the press database: 11 cases relating to cars, three to motorcycles and two to being run over (Table 2).

 

DISCUSSION

Despite the significant concordance between the information from the press and the information from the MIS, the quality of the data on external causes of death in Belo Horizonte needs to be improved, even after routine investigation of deaths done at the IML. This is because of the high proportion of deaths of indeterminate nature and from unspecified traffic accidents that might be qualified through news carried in newspapers. The routine and systematic active search for information in the medical files at the IML was shown to be insufficient to qualify the circumstances of deaths due to traffic accidents, especially with regard to their magnitude and avoidability. Characterization of the means of transport is one of the most important factors for monitoring and prevention policies relating to traffic accidents, along with specifying whether the individual was a pedestrian, cyclist, motorcyclist, driver or passenger. There is a scarcity of information on the means of transport used by the victim, in the sources consulted (incident reports, hospital referrals, information from family members and other sources). As emphasized by Baullinger et al1 (2001), although analysis on newspapers presents some limitations, it assists professionals through qualifying the information on deaths and may be used as a complementary tool for surveillance.

The MIS has great potential as a source of data for analysis, with a view towards implementing and assessing public policies for reducing the numbers of violent deaths. This information system has presented large advances in the coverage and reliability of the data in Belo Horizonte and throughout Brazil. However, the importance of correctly filled-out data relating to referrals, medical files and death certificates for the professionals who forward bodies to the IML, police officers, healthcare professionals and medical examiners.5,6,9

A considerable proportion of the information on accidents or violence reported in the printed press does not form part of the matching with the MIS database, given that the newspapers may not have correctly identified the victims: they may have failed to include the complete name, sex, age and street address of the accident, who the driver or passenger was and the type of vehicle involved. Another limitation is in relation to self-inflicted deaths, because these are generally not published in newspapers because of ethical, family and legal issues, and for this reason they were not qualified in the study. Some external causes are practically not reported, or are left in the background when news or events of great importance for the state or the country are highlighted. This contributes towards possible quantitative losses in cross-referencing the data. Nonetheless, the interference due to data losses that were attributable to non-matching did not have an impact on the results obtained.

According to Kucinski,3 (2000) use of the press as an investigative source can be questioned. As a means of disseminating information to expand the public's knowledge about given facts or events, the media may be tendentious and speculative, thus overvaluing matters that have not yet been proven or explained. Souza et al16 (2006) emphasized that although the printed press may use information in an uncritical and sensationalist manner, it forms an alternative resource for complementing and enriching the data on mortality due to violence and accidents, particularly for an information system with problems regarding its quality.

Construction of a database from the printed press added important information to what was registered in the MIS, thus contributing towards complementing and qualifying the underlying causes of deaths due to external causes, especially with regard to events of indeterminate nature and other unspecified traffic accidents.

The high number of newspaper news items on accidents and violence registered in this study places values on this source of information. It becomes necessary to evaluate the quality of the news carried in the printed press, its capacity to diffuse reliable information and its potential for signaling preventive actions towards reducing the numbers of accidents and violent actions. News items should be added to public policies on urban transportation and public security for facing up to violence in large urban centers.

Routine use of surveillance of news items on external causes of death reported in newspapers is important for comparing and incorporating the information in the MIS. Linkages between the healthcare services and the media may strengthen this initiative.
