BASCD surveys and computer communication. British Association for the Study of Community Dentistry.

The British Association for the Study of Community Dentistry (BASCD) has coordinated National Health Service surveys of the dental health of school children since 1985, when Wales and parts of England were included. Scotland joined in 1987 and Northern Ireland in 1994. This series spans an interesting time in the growth of accessible technology in both statistics and medical research. The purpose of this paper is to chart the development of this data base from pen and paper via microcomputers to the Internet. The annual work now involves calibration of examiners, data collection with portable computers or by manual transcription and subsequent 'punching', paper reports passed to regional coordinators who fill in spread sheets that are passed by e-mail or through posted discs to the data coordinating centre at the Dental Health Services Research Unit at the University of Dundee. The data is checked; statistical analyses are undertaken; a paper is prepared for print and the data is deposited on the BASCD Web Site. Four operating systems and at least eight software packages are used to produce and distribute the survey results.
