There are few empiric data available on the number of measurements required to reliably estimate\n BP<\/jats:styled-content>\n on home\n BP<\/jats:styled-content>\n monitoring (\n HBPM<\/jats:styled-content>\n ).\n <\/jats:p>\n <\/jats:sec>\n \n Methods and Results<\/jats:title>\n \n We analyzed data from 316 community\u2010dwelling adults not taking antihypertensive medication from the\n IDH<\/jats:styled-content>\n (Improving the Detection of Hypertension) study who performed\n HBPM<\/jats:styled-content>\n for 14\u00a0days. The reliability of home\n BP<\/jats:styled-content>\n measurements was assessed using the intraclass correlation coefficient and as the percentage of participants with an absolute difference in home\n BP<\/jats:styled-content>\n <10\u00a0mm\u00a0Hg between weeks. The reliability of home hypertension status was assessed by the \u03ba statistic. In the\n IDH<\/jats:styled-content>\n study, 13.6% of participants had clinic hypertension and 18.0% had home hypertension. Mean home systolic and diastolic\n BP<\/jats:styled-content>\n exhibited excellent reliability and sufficient agreement using the average of 2 morning and 2 evening\n BP<\/jats:styled-content>\n readings for a minimum of 2\u00a0days of\n HBPM<\/jats:styled-content>\n and a single morning and single evening or 2 morning\n BP<\/jats:styled-content>\n readings for a minimum of 3\u00a0days. For diagnosing home hypertension, there was good agreement with a minimum of 3\u00a0days of\n HBPM<\/jats:styled-content>\n using the average of 2 morning and 2 evening measurements or a single morning and single evening\n BP<\/jats:styled-content>\n reading. A greater number of days was required for the other\n HBPM<\/jats:styled-content>\n strategies.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n \n Using the average of morning and evening readings, 3\u00a0days of\n HBPM<\/jats:styled-content>\n are needed to reliably estimate mean home\n BP<\/jats:styled-content>\n and diagnose out\u2010of\u2010clinic hypertension.\n <\/jats:p>\n <\/jats:sec>","DOI":"10.1161\/jaha.118.008658","type":"journal-article","created":{"date-parts":[[2018,10,5]],"date-time":"2018-10-05T05:00:46Z","timestamp":1538715646000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":35,"title":["Number of Measurements Needed to Obtain a Reliable Estimate of Home Blood Pressure: Results From the Improving the Detection of Hypertension Study"],"prefix":"10.1161","volume":"7","author":[{"given":"Natalie A.","family":"Bello","sequence":"first","affiliation":[{"name":"Department of Medicine Columbia University Irving Medical Center New York NY"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joseph E.","family":"Schwartz","sequence":"additional","affiliation":[{"name":"Department of Medicine Columbia University Irving Medical Center New York NY"},{"name":"Department of Psychiatry Stony Brook University Stony Brook NY"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ian M.","family":"Kronish","sequence":"additional","affiliation":[{"name":"Department of Medicine Columbia University Irving Medical Center New York NY"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suzanne","family":"Oparil","sequence":"additional","affiliation":[{"name":"Department of Medicine University of Alabama at Birmingham AL"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.
