Mortality within 1 year after hip fracture surgical repair in the elderly according to postoperative period: a probabilistic record linkage study in Brazil.

OBJECTIVE: The purpose of this study was to assess, by applying probabilistic record linkage (PRL) methodology, the excess mortality and underlying causes of death in a cohort of elderly patients who underwent hip fracture surgical repair during 1995 in Rio de Janeiro, Brazil. DISCUSSION: We searched the Brazilian Hospital Admission Information System (HAIS) for the city of Rio de Janeiro, identifying all cases of elderly patients who had hip fracture surgery between January 1 and December 31, 1995, and by means of the PRL methodology and RecLink software, crosslinked those data with the Brazilian Mortality Information System (MIS) for the same region for a follow-up period of 1 year. We calculated age- and gender-adjusted standardized mortality ratios (SMR) for three periods of time-1-30 days, 31-90 days, and 91-365 days after hospital admission-and analyzed the basic cause of death as reported in the death certificates and noted the death occurred at the index admission or after hospital discharge. RESULTS: We found an overall 21.5% (95% CI 18.2-24.9) mortality rate in 1 year and a statistically significant SMR of 1,080 (95% CI 794-1450) and 512.8 (95% CI 366.4-698.3) for the first two periods, 1-30 days and 31-90 days after hospital admission, respectively. For the last period the SMR displayed a statistically nonsignificant trend of 137 (95% CI 99-183). Even in the first 15 days after the index hospital admission, most deaths (55.1%) occurred after hospital discharge, reinforcing the importance of linking hospital mortality databases with general population mortality information systems. The leading three basic causes of death, as reported in death certificates, were cardiovascular events, falls, and infections. This study represents an example of the application of PRL methodology to produce relevant data on hip fracture, a subject of rising epidemiological importance in developing countries.

[Poverty and HIV/AIDS: anthropological and sociological aspects].

Focusing on the HIV/AIDS epidemic as a summation of several epidemics coexisting in the same space and drawing on Brazilian epidemiological data, we argue that the epidemic there shows variations already described elsewhere, such as feminization, pauperization, juvenization and interiorization, as a result of the deep inequalities characteristic of Brazilian society. We then examine the contributions of three bodies of sociological and anthropological literature related to HIV/AIDS: 1) sociological research and theory on the impact of recent global economic restructuring and social transformation, and its relationship to public health issues; 2) the cross-cultural and cross-national anthropological and sociological literature on structural factors shaping the course of the epidemic in different settings; and 3) the body of anthropological and sociological research on the synergistic effects of HIV/AIDS, social exclusion, and related social problems in pockets of extreme poverty in the large cities of core countries. We conclude that prevention policies for HIV/AIDS should deal comprehensively with diverse dimensions that determine differential vulnerabilities to the epidemic, thus requiring substantial social transformations.

[Reclink: an application for database linkage implementing the probabilistic record linkage method].

This paper presents a system for database linkage based on the probabilistic record linkage technique, developed in the C++ language with the Borland C++ Builder version 3.0 programming environment. The system was tested in the linkage of data sources of different sizes, evaluated both in terms of processing time and sensitivity for identifying true record pairs. Significantly less time was spent in record processing when the program was used, as compared to manual processing, especially in situations where larger databases were used. Manual and automatic processes had equivalent sensitivities in situations where we used databases with fewer records. However, as the number of records grew we noticed a clear reduction in the sensitivity of the manual process, but not in the automatic one. Although in its initial stage of development, the system performed well in terms of both processing speed and sensitivity. Although overall performance of algorithms was satisfactory, we intend to evaluate other routines in the attempt to improve the system's performance.
