Abstract
BackgroundThere are few longitudinal follow-up studies of patients in opioid maintenance treatment (OMT). For this reason we performed a follow-up study of a cohort of 67 women who had used OMT-medications during pregnancy an average of ten years earlier. The aim of our study was to explore how the women were doing over time regarding OMT medication adherence and use of other legal and illegal substances, as well as to evaluate the mortality for the women and custody situation for the children in the cohort. MethodsParticipants were recruited from two cohorts in our previous pregnancy study covering women who gave birth from 2004 to 2009. Sixty-seven women agreed to be interviewed, which is 73% of the eligible women from our original study. We developed a questionnaire, which we used in the interview, that focused primarily on these women's current life situation (custody of child they had delivered, the use of medications in OMT and other legal and illegal substances, and several other health and social aspects of the participants' lives). ResultsTwo women had died prior to the follow-up. Eighty-one percent of the women had custody of the child they had delivered in our pregnancy study and half the women were single parents. Fifty-four percent of the women were employed. At follow-up, 42% of the women were in methadone maintenance treatment (MMT), 39% were in buprenorphine maintenance treatment (BMT), and 19% had left OMT. One-third of the women had changed their OMT medication during the follow-up period. The majority (77%) were satisfied with their current OMT medication. The women in MMT seemed to be more severe substance dependent than the rest of the participants. There was little use of legal and illegal substances at follow-up, especially among women with custody of their child. The frequency of substance use was low. Fourteen percent of the women were in the process of leaving OMT and another half of the women wanted to leave OMT, but had no plan for how and when. ConclusionThis follow-up study describes a predominantly well rehabilitated cohort of women who had given birth while in OMT ten years earlier. The majority of the women had custody of their children and used very few legal and illegal drugs. Our findings may be explained partly from a life course perspective, with the women having experienced turning points when starting OMT or becoming mothers.
