RESUMEN
We surveyed the generation rate of health statistics by medical records offices of the 78 hospitals and its automation rate using computerized hospital information system. Structured questionnaire was given to one medical record officer of each hospital. Items in the questionnaire was selected from statistics required for hospital service evaluation or OECD health statistics. More than 50% of the medical record office generated questioned health statistics, and most of them was automated. Because many of the medical record offices of the hospitals are producing essential health statistics and automated, there is a possibility that we can collect and use these datas to build up national health database if adequate standardization procedure can be implemented.
