Qualidade da informação sobre causas externas no Sistema de Informações Hospitalares

Abstract

OBJECTIVE:To analyze the coverage and quality of the data on hospitalizations due to external causes in the Hospital Information System of the Brazilian National Health System. METHODS:Hospitalizations recorded in the Hospital Information System of 11 hospitals in two municipalities (Londrina and Maringá, Southern Brazil), in 2004, were compared with hospitalizations identifi ed as consequences of external causes through investigating medical records, complemented with mortality and pre-hospital data. The crude agreement rate, sensitivity and positive predictive value were calculated. The profi le of groups of hospitalization causes recorded in the System was compared with that obtained from investigations. RESULTS:In Londrina, 3,002 hospitalizations due to external causes were recorded in the System and, in Maringá, 1,403. The investigations found 4,018 and 2,370, respectively. The System presented high positive predictive values for hospitalizations due to external causes in both municipalities: 97.7% in Londrina and 98.6% in Maringá. However, the sensitivity was low: 57.3% in Maringá and 73% in Londrina, thus denoting underrecording of these causes. Comparison between the profi les of the types of causes revealed that there was underestimation of some causes in the System, especially regarding accidents due to exposure to inanimate mechanical forces, assaults and intentional self-harm. CONCLUSIONS:Underrecording of hospitalizations due to external causes and some distortions regarding the types of causes occurred in the Hospital Information System in both municipalities. Detection of these defi ciencies may contribute towards the process of improving the quality of the information in this System.

Acidentes de trânsito em Belo Horizonte: o que revelam três diferentes fontes de informações, 2008 a 2010

“…Our findings show the liability of different sources with different purposes and point of view to collect data, and justify the increasing use of such databases. Linking information from different, more complete and trustworthy sources 10,11 can be a reliable strategy for the assessment and characterization of Information Systems, and also for the improvement of actions to reduce TA. All three databases lacked some information, which confirms the findings of previous studies on Information Systems 12 , reflecting inadequate fulfilling of data regarding important risk factors for severe and fatal accidents: alcohol intake by the driver and misuse of safety equipment 1 .…”

Perfil das internações e óbitos hospitalares por tuberculose

“…On the other hand, this use has advantages already mentioned in other studies, for example, making available data routinely collected for all hospitalizations of the Unified Health System, which represent approximately 70% of admissions in the country. (9) In the case of tuberculosis, mortality data of this system can be even more accurate than those contained in the Information System on Mortality, since for many cases tuberculosis is not the cause of death. Thus, this study on hospital mortality provides important epidemiological information that allows knowing aspects of the disease profile and the role of public health services.…”

“…But hospital admissions due to external causes coded as natural causes in the database were not included in the study. Tomimatsu et al 72 assessed coverage and quality of hospital admission information in Londrina and Maringá based on AIH medical reports. In Londrina there was high underreporting of RTA with an increase in the number of hospital admissions to 988 from 492 after reclassifi cation.…”
