For bipolar disorder, the use has been more limited and no studies exist concerning accuracy of bipolar I diagnoses in registers. We have collected an unselected twin sample for a study of bipolar I disorder. We report here the diagnostic procedures and accuracy of bipolar I diagnoses in a nation-wide hospital discharge registry. We evaluated also the accuracy of the medical record-based best-estimate diagnoses, comparing these with the SCID interview diagnoses. From the National Hospital Discharge Register we identified all like-sex twins, born 1940-1957, (N=42), and all like- or opposite-sex twins, born 1961-1969, (N=15), who had at least once a diagnosis of bipolar I disorder. The best-estimate diagnoses based on medical records, and were made by two doctors blind to each other, and according to DSM-IV-criteria. Diag-noses were then confirmed by SCID interviews, with the mi-nimum follow-up time after the first admission being 6 years. The accuracy of bipolar diagnoses in the register was 92% and 87%, accordingly. When comparing the best-estimate diagnoses to SCID interview diagnoses, there was one false positive case in the first sample, 3.4% [95% CI 0.1% to 7.8%], and none in the second sample. Our study shows that a diagnosis of bipolar I disorder in the hospital discharge register, or if based only on medical records, is highly reliable and stable. These results strengthen the usefulness of regis-ters also in bipolar disorder.<\/jats:p>","DOI":"10.1017\/s0924270800035535","type":"journal-article","created":{"date-parts":[[2016,7,26]],"date-time":"2016-07-26T01:24:09Z","timestamp":1469496249000},"page":"106-109","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":49,"title":["Accuracy of register- and record-based bipolar I disorder diagnoses in Finland; a study of twins"],"prefix":"10.1017","volume":"12","author":[{"given":"T.","family":"Kiesepp\u00e4","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Partonen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Kaprio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"L\u00f6nnqvist","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2015,9,18]]},"reference":[{"key":"S0924270800035535_ref015","volume-title":"The Structured Clinical Interview for DSM-IV Axis I and II Disorders (SCID I-II)","author":"Spitzer","year":"1997"},{"key":"S0924270800035535_ref014","doi-asserted-by":"publisher","DOI":"10.1001\/archpsyc.55.6.492"},{"key":"S0924270800035535_ref013","volume-title":"Diagnostic and Statistical Manual of Mental Disorders","year":"1994"},{"key":"S0924270800035535_ref012","doi-asserted-by":"publisher","DOI":"10.3109\/07853899409147880"},{"key":"S0924270800035535_ref011","first-page":"179","article-title":"The Finnish Twin Registry: Formation and compilation, queslionnare study, zygosity determination procedures and research program","volume":"24B","author":"Kaprio","year":"1978","journal-title":"Progr Clin Biol Res"},{"key":"S0924270800035535_ref010","volume-title":"Diagnostic and Statistical Manual of Mental Disorders","year":"1987"},{"key":"S0924270800035535_ref009","volume-title":"Injuries and Causes of Death","year":"1967"},{"key":"S0924270800035535_ref006","first-page":"57","article-title":"Accuracy of register-based schizophrenia diagnoses in a genetic study","volume":"13","author":"M\u00e4kikyr\u00f6","year":"1998","journal-title":"Lump Psychiatry"},{"key":"S0924270800035535_ref005","doi-asserted-by":"publisher","DOI":"10.1192\/bjp.173.6.494"},{"key":"S0924270800035535_ref004","doi-asserted-by":"publisher","DOI":"10.1001\/archpsyc.55.1.67"},{"key":"S0924270800035535_ref003","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-8628(19970725)74:4<353::AID-AJMG3>3.0.CO;2-Q"},{"key":"S0924270800035535_ref002","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291700035856"},{"key":"S0924270800035535_ref001","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-0327(98)00049-4"},{"key":"S0924270800035535_ref008","doi-asserted-by":"publisher","DOI":"10.1001\/archpsyc.1993.01820210033004"},{"key":"S0924270800035535_ref007","doi-asserted-by":"publisher","DOI":"10.1192\/bjp.130.4.330"}],"container-title":["Acta Neuropsychiatrica"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0924270800035535","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,8]],"date-time":"2019-05-08T16:37:08Z","timestamp":1557333428000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0924270800035535\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2000,9]]},"references-count":15,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2000,9]]}},"alternative-id":["S0924270800035535"],"URL":"https:\/\/doi.org\/10.1017\/s0924270800035535","relation":{},"ISSN":["0924-2708","1601-5215"],"issn-type":[{"value":"0924-2708","type":"print"},{"value":"1601-5215","type":"electronic"}],"subject":[],"published":{"date-parts":[[2000,9]]},"assertion":[{"value":"Copyright \u00a9 Scandinavian College of Neuropsychopharmacology 2000","name":"license","label":"License","group":{"name":"copyright_and_licensing","label":"Copyright and Licensing"}}]}}
