This was demonstrated in general practice computer databases by conducting a routine search and constructing a frequency distribution of the 20 992 blood pressure readings using mathematical software for a personal computer. The charts produced have a practical application in providing an audit tool whereby nurses and doctors can be made aware of this source of error, providing an opportunity for improving measurement technique and developing more refined and realistic protocols for blood pressure management in general practice. The same principles may be applied to other measurements made in the GP consultation such as peak expiratory flow rate. © 1995 Oxford University Press Part 2: Provider Issues nationallicence blood pressure nationallicence terminal digit preference nationallicence measurement in general practice nationallicence general practice computing nationallicence Mathematical Medicine and Biology: A Journal of the IMA Oxford University Press 12/3-4(1995-09), 275-281 1477-8599 12:3-4<275 1995 12 imammb https://doi.org/10.1093/imammb/12.3-4.275 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1093/imammb/12.3-4.275 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- WINGFIELD DAVID Department of Public Health and Primary Care, Charing Cross and Westminster Medical School, Chelsea, 369 Fulham Road, London SW10 9NH, UK NATIONALLICENCE 773 0- Mathematical Medicine and Biology: A Journal of the IMA Oxford University Press 12/3-4(1995-09), 275-281 1477-8599 12:3-4<275 1995 12 imammb Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
