The ''true'' number of strokes in the population was estimated by screening for non-stroke diagnoses in death certificates and hospital discharge records and by a period of intensified search for otherwise unrecognized non-hospitalized stroke cases. Applying strict stroke criteria, the proportion of false-positive diagnoses was 10% and false-negative 17% in official mortality statistics. Among patients discharged alive from hospital, there were 32 % false-positive and 6 % false-negative stroke diagnoses. In the MONICA registry, the proportion of false-negative cases was 6 % in fatal cases and 4% in non-fatal cases. Diagnostic information for subtyping stroke improved over time in non-fatal cases but remained essentially unchanged in fatal cases. We conclude that official mortality statistics give a reasonably good estimate of fatal stroke cases in Sweden, whereas hospital discharge records reflect poorly the incidence of stroke in the population. The overall quality of the population-based MONICA registry is good, although 4% of all strokes are missed. The proportion of unspecified stroke is substantial and changes over time; this makes longitudinal studies of stroke subtype difficult.<\/jats:p>","DOI":"10.1159\/000110933","type":"journal-article","created":{"date-parts":[[2007,11,7]],"date-time":"2007-11-07T05:12:54Z","timestamp":1194412374000},"page":"204-213","source":"Crossref","is-referenced-by-count":107,"title":["Measuring Stroke in the Population: Quality of Routine Statistics in Comparison with a Population-Based Stroke Registry"],"prefix":"10.1159","author":[{"given":"Birgitta","family":"Stegmayr","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kjell","family":"Asplund","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[1993,1,28]]},"container-title":["Neuroepidemiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/110933","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000110933","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T14:58:08Z","timestamp":1777647488000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000110933"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1993,1,28]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000110933","archive":["Portico"],"relation":{},"ISSN":["0251-5350","1423-0208"],"issn-type":[{"value":"0251-5350","type":"print"},{"value":"1423-0208","type":"electronic"}],"subject":[],"published":{"date-parts":[[1993,1,28]]}}}
