Health data and statistics are central to the provision of an efficient and effective health service. The health status and health needs of the population must be ascertained and delivery of services appropriately planned and targeted. In addition, service provision needs to be carefully monitored, and its contribution towards health and social gain assessed. These requirements are stated explicitly in the Department's recent statement of strategy and are reflected in improvements to the timeliness and comprehensiveness of existing information systems and in the development of new databases and analysis tools.
Some of the more important initiatives are as follows, but this is by no means an exhaustive list. The Hospital In-Patient Enquiry which captures detailed information on all hospital discharges from publicly-funded acute hospitals has been significantly improved in recent years. It has now reached very high levels of coverage and timeliness. It is an integral part of the Department's casemix system which is used in the allocation of hospital resources and is also a valuable source of clinical and epidemiological information.
A new public health information system has been established. This provides a minimum common data set of health indicators for morbidity and mortality by county and health board area. The system has its own software which includes mapping and graphics facilities. It has been developed in conjunction with the directors of public health in each health board and is an invaluable tool in examining trends in health on a regional basis. An up-dated version of the public health information system will be released in the next few weeks.
The health promotion unit of my Department recently commissioned the centre for health promotion studies at University College Galway to undertake the first National Lifestyle Survey — SLAN — in Ireland. This is now well under way and preliminary data on a range of health status measures will be available later this year.
