This prospective patient-preference study examined the effectiveness in practice of methadone versus buprenorphine maintenance treatment and the beliefs of subjects regarding these drugs. A total of 361 opiate-dependent individuals (89% of those eligible, presenting for treatment over 2 years at a drug service in England) received rapid titration then flexible dosing with methadone or buprenorphine; 227 patients chose methadone (63%) and 134 buprenorphine (37%). Participants choosing methadone had more severe substance abuse and psychiatric and physical problems but were more likely to remain in treatment. Survival analysis indicated those prescribed methadone were over twice as likely to be retained (hazard ratio for retention was 2.08 and 95% confidence interval [CI] = 1.49-2.94 for methadone vs. buprenorphine), However, those retained on buprenorphine were more likely to suppress illicit opiate use (odds ratio = 2.136, 95% CI = 1.509-3.027, p < .001) and achieve detoxification. Buprenorphine may also recruit more individuals to treatment because 28% of those choosing buprenorphine (10% of the total sample) stated they would not have accessed treatment with methadone.
SummaryVery little attention has been paid to the invisible epidemic of substance misuse among older people in the UK. This article looks at the prevalence of substance misuse in the people over the age of 60. The reasons for difficulty in diagnosing substance misuse are explored and ways to improve diagnostic ability are discussed. Substance misuse leads to severe physical and psychiatric morbidity that is being managed by meagre resources. The article provides recommendations on specific issues related to interventions, biological and psychosocial, and training of psychiatrists.
Purpose -The aim of this study is to explore the characteristics of a group of patients over 50 years old who are entering a substitution treatment programme for opioid dependence and to compare the characteristics of this group with those aged under 50 who are enrolled in the same substitution treatment programme.Design/methodology/approach -This is a cross sectional survey involving 92 cases in the 50 and above age group and 194 cases in the under 50 age group from community drug and alcohol services. Data were collected on demographic details, substance misuse and treatment history and progress with treatment. All the data were analysed using the Statistical Package for the Social Sciences (SPSS), version 1.1. Statistical significance between fewer than 50 and 50 þ groups were assessed using Fisher's exact test.Findings -Amongst the 92 in the group 50 years and above, 67 (average dose ¼ 63.25 mg) were on methadone maintenance (average dose ¼ 63.25 mg) and 19 (average dose ¼ 10.37 mg) on buprenorphine. In total, 11 per cent started using opiates after the age of 50. Sixty per cent used other substances out of which 31 per cent used multiple substances. Benzodiazepines, cocaine and amphetamines were the common substances of misuse. Thirty seven were infected with HCV. Comorbid rates for physical and mental illnesses were 64 per cent and 62 per cent, respectively. Nearly 86 per cent achieved good compliance with the treatment programme. Statistically higher rates of being single, lacking stable accommodation, prescription of buprenorphine, high dose prescriptions and lower rates of blood-borne viruses, physical health and mental health, past forensic history were found in the under 50 age group compared with the 50 þ age group.Practical implications -There are a considerable number of patients above the age of 50 in maintenance treatment and they differ from the less than 50 age group. Old age and substance misuse psychiatrists should be aware of the prevalence of comorbid substance misuse, physical (including blood borne viruses) and psychiatric disorders in this population. Further research is required in this neglected area and a service provision should be based on such robust research.Originality/value -This is the first study to the authors' knowledge that compares the demographic and treatment profiles of under 50 and over 50 years by age of patients in a methadone maintenance treatment programme. It clearly points to significant differences in the profiles based on age which will have implications for service provision which will have to take into account these age-related differences in particular related to physical health and social needs.
