A B S T R A C TBackground: Historically, issues relating to problem substance use among older people have received little attention, and have only recently been recognised. Methods: A literature review of relevant material was conducted in November 2015 to assess current outcome research among older adults treated for opioid dependence. Multiple electronic databases were searched and results were supplemented by grey literature, library and online searches, and relevant references within selected articles. Retrieved articles were assessed for relevance against the inclusion and exclusion criteria. Results were reviewed to identify major findings and recommendations. Results: A total of 76 titles were included in the review. Most research conducted on older adults involves alcohol and prescription medications. Older drug users are growing in number and have a unique profile, with many presenting for treatment for the first time aged 50-70 years. Findings reveal (1) opioid treatment numbers are decreasing, however the average age of treatment admissions is increasing, (2) there is no consensus on what old is (3) two distinct types of older opioid substance users exist (early/late onset), (4) older clients achieve better treatment outcomes than younger counterparts, and (5) older women achieve better treatment outcomes than men. Conclusions: Findings suggest that little is known about treatment outcomes among older people. Problematic drug use (of which opioids make up the largest proportion) had been incorrectly assumed to end as patients age. Defining an age limit for 'older' is important. Addiction and healthcare services must anticipate and prepare for increased demand by this group.
BackgroundComprehensive information on the incidence and duration of hepatitis C virus (HCV) infection for people who inject drugs (PWID) in Ireland is not available. We created an incidence curve of injecting drug use in Ireland and subsequently estimated incidence of hepatitis C virus (HCV) infection.MethodsAnonymised data from the National Drug Treatment Reporting System (NDTRS) were used to identify all people who inject drugs (PWIDs) and who entered drug treatment for the first time between 1991 and 2014. A curve, estimating the incidence of injecting, was created to plot PWIDs by year of commencing injecting. The curve was adjusted for missing data on PWIDs in treatment and for PWIDs who were never treated. An adjustment was made to account for injectors who had never shared injecting equipment. The incidence of HCV infection and chronic infection in PWIDs was estimated by applying published rates.ResultsBetween 1991 and 2014, 14,320 injectors were registered on NDTRS. The majority were young (median age 25 years), male (74%), lived in Dublin (73%) and injected an opiate (e.g. heroin) (94%). The estimated total number of injectors up to the end of 2014 was 16,382. An estimated 12,423 (95% CI 10,799-13,161) were infected with HCV, and 9,317 (95% CI 8,022-9,996) became chronically infected. The estimated annual number of new HCV infections among PWIDs increased steeply from the late 1970s and peaked in 1998. By 2014, almost 30% of injectors were estimated to have been infected for over 20 years.ConclusionsThis is the first comprehensive national estimate of the incidence of HCV in PWIDs in Ireland and will inform planning and developing appropriate health care services.Electronic supplementary materialThe online version of this article (doi:10.1186/s41124-017-0024-1) contains supplementary material, which is available to authorized users.
By accessing addiction treatment services recorded in routine national drug treatment data, the characteristics of Irish Travellers were analyzed to understand their needs and develop policies to tackle issues faced by this community. The number of Traveller cases accessing services increased by 163% between 2007 and 2010. Alcohol and opiates were the most common problem substances reported. Traveller women reported high rates of problem opiate use and risky injecting behaviors, contrary to the perception that problem substance use is a predominantly male issue. This presents a challenge to services to provide targeted, effective services to Travellers with problem substance use.
<b><i>Introduction:</i></b> Given the increased prevalence of cannabis use in Ireland and increase in cannabis potency, this study aimed to estimate the size of the potential population in Ireland that may be in need of cannabis treatment and the percentage of people with cannabis use disorder (CUD) who actually access treatment. We also compared the profile of those with CUD in the general population to those who receive treatment for their cannabis use to explore whether certain subgroups are more or less likely to enter treatment. <b><i>Method:</i></b> This was a retrospective, multi-source database study. Data were obtained from (1) Ireland’s 2014/2015 national general population survey (GPS) on drug use and (2) treatment data from the Irish National Drug Treatment Reporting System (NDTRS) for 2015. The profiles of GPS cases with CUD and NDTRS cases were compared using 2-sided <i>t</i> tests designed for independent samples. <b><i>Results:</i></b> The prevalence of last year cannabis use among adults aged 15 and older was 6.5% and the prevalence of CUD was 2.6%, representing 94,515 of the Irish population. A total of 4,761 cases entered treatment for problem cannabis use. NDTRS treatment cases were significantly more likely than GPS cases to be unemployed (63.7% vs. 26.6%) and have no or primary level only educational attainment (56.3% vs. 21.2%). Over half (53.3%) of NDTRS cases first used cannabis before the age of 15 years, compared to 14.7% of CUD cases in the population. <b><i>Discussion/Conclusion:</i></b> Our findings suggest that earlier users and those with more complex or disadvantaged lives are more likely to seek treatment. A broad population health approach that engages multiple sectors such as health, social welfare, and education is recommended to ensure that there is increased opportunity for people with CUD to be identified and signposted towards treatment.
