Is South Africa being spared the global opioid crisis? A review of trends in drug treatment demand for heroin, nyaope and codeine-related medicines in South Africa (2012–2017)

Abstract

IntroductionSouth Africa has seen a sharp increase in treatment admission trends for opioids despite beliefs that rates of opioid use remain low and do not represent a major problem. To advocate for the extension of Opioid Use Disorder (OUD) treatment and harm minimisation services in South Africa, better estimates of the extent of opioid use is needed. This paper responds to this need by describing (i) trends in treatment utilization for opioid-related problems in South Africa and (ii) differences in the profile of patients accessing treatment for different classes of opioids - heroin, ‘nyaope’ and codeine use. MethodsData were collected from 83 specialist treatment centres participating in the South African Community Epidemiology Network on Drug Use between 2012 and 2017. Descriptive analyses were conducted to describe the sociodemographic profile of patients and multiple logistic regression was used to explore socio-demographic and clinical factors associated with admission to treatment for opioid use disorders (OUD) . ResultsFrom January 2012 to December 2017, data from 11 2032 treatment episodes were collated. Of these, 20 319 (18.1%) were from patients admitted for an OUD. Over time, the proportion of overall opioid-related admissions increased significantly from 16.1% of all admissions in 2012 to 20.0% in 2017 (p <0.001). Data also suggests a significant increase in the overall proportion of patients reporting injection drug use, from 1.6% in 2013 to 3.5% in 2017 (p <0.001). Clear differences in employment status, referral sources between classes of opioids were also noted. ConclusionOver the last 5 years, South Africa has seen an increase in the proportion of opioid related disorders (OUD) treatment admissions. Public health interventions, evidence-based harm reduction approaches and improving access to treatment are among the interventions urgently needed to reduce the harms associated with the increased use of opioids in South Africa.
