These units have now been established in many countries and have been found to be effective and efficient, saving money and unnecessary emergency department visits and hospital admissions. To our knowledge, no such model has been described in the United States. A PubMed search using a combination of \u201cearly pregnancy unit,\u201d \u201cearly pregnancy assessment clinic,\u201d and \u201cUnited States,\u201d \u201cU.S.,\u201d and \u201cAmerica\u201d on May 14, 2017, yielded no results. Denver Health, a safety net hospital in Denver, Colorado, has established the first known early pregnancy unit in the United States. Patients with positive urine pregnancy test results who are in their first trimester by best estimation, have not had a prior ultrasound examination, and present to their primary care providers with pain, bleeding, history of an ectopic pregnancy, history of a tubal ligation, or conception with an intrauterine device in place are eligible to be evaluated in the early pregnancy unit. This article describes our clinical setup, methods, and findings in the first 2 years of the unit's inception with the intention of serving as a model for the establishment of more early pregnancy units throughout the United States.<\/jats:p>","DOI":"10.1002\/jum.14474","type":"journal-article","created":{"date-parts":[[2017,11,9]],"date-time":"2017-11-09T06:26:48Z","timestamp":1510208808000},"page":"1533-1538","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["An Early Pregnancy Unit in the United States: An Effective Method for Evaluating First\u2010Trimester Pregnancy Complications"],"prefix":"10.1002","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2042-601X","authenticated-orcid":false,"given":"Polina","family":"Rovner","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology University of Colorado School of Medicine Aurora Colorado USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Elaine","family":"Stickrath","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology Denver Health Medical Center Denver Colorado USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meredith","family":"Alston","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology Denver Health Medical Center Denver Colorado USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kirsten","family":"Lund","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology Denver Health Medical Center Denver Colorado USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2017,11,9]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM198807283190401"},{"key":"e_1_2_7_3_1","first-page":"46","article-title":"Ectopic pregnancy: United States, 1990\u20131992","volume":"44","author":"Centers for Disease Control and Prevention","year":"1995","journal-title":"MMWR Morb Mortal Wkly Rep"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajog.2012.12.038"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.302.6776.577"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/GRF.0b013e3180305ef4"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1701-2163(16)35184-2"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1479-828X.2009.00954.x"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11845-007-0013-2"},{"volume-title":"Ectopic Pregnancy and Miscarriage: Diagnosis and Initial Management of Early Pregnancy of Ectopic Pregnancy and Miscarriage. 5: Early Pregnancy Assessment Units","year":"2012","author":"National Collaborating Center for Women's and Children's Health","key":"e_1_2_7_10_1"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1701-2163(16)34302-X"},{"key":"e_1_2_7_12_1","unstructured":"United States Census Bureau.Quick facts: Denver County Colorado.
