Completeness of notifications of accidents involving venomous animals in the Information System for Notifiable Diseases: a descriptive study, Brazil, 2007-2019

OBJECTIVE

to describe the completeness of notifications of accidents involving venomous animals held on the Notifiable Health Conditions Information System (SINAN), in Brazil and its macro-regions, from 2007 to 2019.

METHODS

we analyzed essential and non-mandatory fields for snakebite, spider bite and scorpion sting notifications, considering the following completeness categories: Excellent (≤5.0% incompleteness), Good (5.0% to 10.0%), Regular (10.0% to 20.0%), Poor (20.0% to ≤50.0%) and Very Poor (>50.0%). Proportional change in completeness between 2007 and 2019 was estimated.

RESULTS

1,871,462 notifications were investigated. The "localized manifestations", "systemic manifestations", "case classification", "case progression" and "zone of occurrence" fields had excellent or good completeness. Completeness was regular or poor for the "schooling" and "race/color" fields. The "occupation" field was predominantly poorly or very poorly filled in. There was a proportional worsening in completeness (PC<0) in most regions for the "zone of occurrence", "case progression" and "schooling" fields.

CONCLUSION

completeness of most fields improved, although socioeconomic and occupational fields require more attention.

Recovering missing mesothelioma deaths in death certificates using hospital records

BACKGROUND

In Brazil, underreporting of mesothelioma and cancer of the pleura (MCP) is suspected to be high. Records from death certificates (SIM) and hospital registers (SIH-SUS) can be combined to recover missing data but only anonymous databases are available. This study shows how common data can be used for linkage and as an assessment of accuracy.

METHODS

Mesothelioma (all sites, ICD-10 codes C45.0-C45.9) and cancer of the pleura (C38.4) were retrieved from both information systems and combined using a linkage algorithm. Accuracy was examined with non-anonymous databases, limited to the state of São Paulo.

RESULTS

We found 775 cases in death certificates and 283 in hospital registers. The linkage matched 57 cases, all accurately paired. Three cases, 0.4% in SIM and 1.3% in SIH-SUS, could not be matched because of data inconsistencies.

CONCLUSIONS

A computer linkage can recover MCP cases from hospital records not found in death certificates in Brazil.

Gathering Occupational Health Data from Informal Workers: The Brazilian Experience

This study describes how occupational health data have been gathered by the Brazilian Unified Health System (SUS) to provide morbidity and mortality estimates for formal and informal workers. In 2007, data on work-related diseases and injuries was incorporated into the compulsory notification system (SINAN) and analyzed by the SUS occupational health service network, which covers all Brazilian states. However, this work has not been fully implemented, resulting in the large-scale undercounting and underreporting of cases, particularly in relation to informal workers. This is suggestive of barriers that prevent access to services and good quality health care. The inclusion of work-related diseases and injuries in SINANs appears to be a feasible strategy for the collection of useful data for the surveillance of the entire universe of workers, particularly in countries where informal workers prevail within the labor force. Attention needs to be paid to the disparities in access and quality that affect low-paid, informal workers.
