Study designs based on the identification of cases are frequently utilized when undertaking epidemiological research. Traditionally these have been mainly based on identification of cases from hospital records. This paper discusses the use of study designs based on the identification of cases focusing on their application to research data derived from primary care. The designs are discussed in the context of using computerized clinical data derived from primary care. The traditional case-control design is considered, with emphasis on the identification of cases and the selection of controls. A common problem when using primary care research databases is that information about potential confounding variables is often limited. Case-only designs, specifically the case-crossover and the within-person case-series, offer alternative designs that aim to overcome problems with confounding. The principles underlying these case-only designs are presented along with examples of their use. The advantages and limitations of the different designs are discussed.

The response of healthcare services to new information systems depends upon, among other factors, their local organization. This study aimed at comparing the chemotherapy and radiotherapy production registers for the cities Rio de Janeiro and Belo Horizonte, Brazil, in the Ambulatory Information System of the Unified Brazilian Health System (in Portuguese, SUS) between November/1998 and February/2003. Both cities showed a pattern of increase for the chemotherapy production series, while the radiotherapy series showed such increase only for Rio de Janeiro. Comparing Box-Jenkins models for each series, Rio de Janeiro showed a delay of three months in recording production, due to public services. In Belo Horizonte, the delay was shorter than in Rio de Janeiro and there was no difference between public and non-public services. The observed differences between the cities seem to be associated with the fact that Belo Horizonte already had a mechanism to control and evaluate production before the introduction of the system in 1998.
