A mainframe relational database management system (RDBMS), ORACLE, has been applied to small animal clinical records to facilitate storage and querying of case data for clinical and epidemiological use. Coded records are entered into the computer via a “user-friendly” interface which validates the input. Clinicians' queries similarly utilise an interface that generates query commands from four simple queries. Epidemiologists' queries, in contrast, require considerable flexibility and so use the main RDBMS language, SQL*Plus. A data administrator manages the security and integrity of the RDBMS. 相似文献

A case-control study was conducted to investigate the efficacy of several vaccines in protecting against canine kennel cough. Cases and controls were selected from a random sample of veterinary practices in the UK, and relevant information was collected using postal questionnaires. The relationship between vaccinal status and the occurrence of kennel cough was examined using a linear logistic model. Vaccination against Bordetella bronchiseptica and canine parainfluenza virus was associated with reduced risks of the disease, as indicated by a decrease in the log odds (log relative risk) of disease in vaccinated animals, when integrated with usual vaccination strategies. Statistical interaction between these two vaccines and adenovirus vaccines was identified. 相似文献

Modelling the epidemiology of foot-and-mouth disease (FMD) has been undertaken since the early 1970s. We review here clinical factors and modelling procedures that have been used in the past, differentiating between those that have proved to be more relevant in controlling FMD epidemics, and those that have showed less significance. During the 2001 UK FMD epidemic, many previously developed FMD models were available for consideration and use. Accurate epidemiological models can become useful tools for determining relevant control policies for different scenarios and, conversely, inaccurate models may become an abuse for disease control. Inaccuracy presents two opposing difficulties. Firstly, too much control (in terms of animal slaughter for 2001) would negatively impact the farming community for many subsequent years, whilst too little control would permit an epidemic to persist. Accuracy however, presents the optimal permutation of control measures that could be implemented for a given set of conditions, and is a prerequisite to boosting public confidence in the use of epidemiological models for future epidemics. 相似文献
