The patients were admitted between 1995 and mid-2000 and were followed until December 2000 or discharge. Up to June 11, 1998, individual psychosocial counseling was provided; after this date individual counseling was replaced with group counseling. Clinical data were collected from patient records and from a laboratory database. Rates of drugpositive urine analyses during different time periods were measured.Results: The mean observation time was 2.5 years for all patients. The one-year retention rate was 84 percent, and the two-year rate was 65 percent, with no major differences between the two counseling groups. Almost all patients relapsed to illicit drug use. Discharged patients had a significantly higher rate of positive urine samples (21 percent versus 9 percent) than patients who remained in treatment. Also, low methadone dose and younger age predicted discharge from treatment.Conclusion: The frequent urine monitoring showed that illicit drug use was rather common, even in a program with structured psychosocial interventions, although it was lower than in other studies. This testing policy can be used for early identification of patients at risk for drop-out or discharge who should be offered complementary interventions.<\/jats:p>","DOI":"10.5055\/jom.2007.0036","type":"journal-article","created":{"date-parts":[[2018,2,2]],"date-time":"2018-02-02T17:07:48Z","timestamp":1517591268000},"page":"27-34","source":"Crossref","is-referenced-by-count":38,"title":["Patterns of illicit drug use and retention in a methadone program: A longitudinal study"],"prefix":"10.5055","volume":"3","author":[{"given":"Ingrid","family":"Davstad, MA","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marlene","family":"Stenbacka, PhD","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anders","family":"Leifman, MSE","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Olof","family":"Beck, PhD","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Seher","family":"Korkmaz, MD, PhD","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anders","family":"Romelsjo, MD, PhD","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3008","published-online":{"date-parts":[[2007,1,1]]},"container-title":["Journal of Opioid Management"],"original-title":[],"link":[{"URL":"https:\/\/wmpllc.org\/ojs\/index.php\/jom\/article\/download\/1163\/1175","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/wmpllc.org\/ojs\/index.php\/jom\/article\/download\/1163\/1175","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,5,2]],"date-time":"2023-05-02T18:17:35Z","timestamp":1683051455000},"score":1,"resource":{"primary":{"URL":"https:\/\/wmpllc.org\/ojs\/index.php\/jom\/article\/view\/1163"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007,1,1]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2007,1,1]]}},"URL":"https:\/\/doi.org\/10.5055\/jom.2007.0036","relation":{},"ISSN":["1551-7489","1551-7489"],"issn-type":[{"value":"1551-7489","type":"electronic"},{"value":"1551-7489","type":"print"}],"subject":[],"published":{"date-parts":[[2007,1,1]]}}}
