The total work load of the sole cardiac surgery unit in South Australia has been analysed by means of a computer-based data retrieval system. The review covers the period 1949--75 inclusive. This study analyses the case-loads year by year, in total, and in different diagnostic categories, and has allowed conclusions to be drawn about surgical needs relative to population figures. From these figures future trends in requirements for cardiac surgical facilities have been deduced. There are many lessons to be learnt by maintaining an easily recoverable set of data for all the surgery performed in any cardiac surgery unit. This type of analysis makes it possible to maintain surveillance of demands on resources and of the results of the surgery performed. Because of the structure and situation of the community of South Australia and the fact that it is served by a single open heart unit, the pattern of this series may truly represent the optimum cardiac surgery case-load for any modern westernised community of comparable size.
通过一个基于计算机的数据检索系统，对南澳大利亚唯一的心脏外科单元的总工作量进行了分析。该综述涵盖了1949年至1975年（含）期间。本研究逐年分析了病例数量，包括总数以及不同诊断类别，并据此得出了相对于人口数据的手术需求结论。从这些数据中推断出了心脏外科设施需求的未来趋势。对于任何心脏外科单元所进行的所有手术，维护一组易于恢复的数据能让人学到很多经验教训。这种类型的分析使得监测资源需求和所实施手术的结果成为可能。由于南澳大利亚社区的结构和情况，以及该地区由一个单一的心脏直视手术单元提供服务这一事实，该系列的模式可能真实地代表了任何规模相当的现代西方化社区的最佳心脏手术病例数量。
