Indicators of substance abuse treatment demand in Cape Town, South Africa (1997-2001)

The Opioid Epidemic in Africa And Its Impact

Purpose of review

Opioid use disorder (OUD) is a global phenomenon and is on the rise in Africa, denoting a shift from historical patterns of drug transport to internal consumption. In contrast, opioids for clinical pain management in Africa remain among the least available globally. This region also has the highest HIV and HCV disease burden, and the greatest shortages of health workers and addiction treatment. We undertook a systematic review of the literature to describe opioid use in Africa and how it is being addressed.

Recent findings

A total of 84 articles from 2000 to 2018 were identified. Descriptions of country-specific populations and patterns of opioid misuse were common. A smaller number of articles described interventions to address OUD.

Summary

OUD occurs in sub-Saharan Africa, with attendant clinical and social costs. Evidence-based policies and health system resources are needed to promote OUD prevention and management, and infectious disease transmission reduction.

Heroin treatment demand in South Africa: trends from two large metropolitan sites (January 1997-December 2003)

Accurate prevalence data on heroin use, that points to where problems exist and the extent of these problems, is necessary to guide the formulation of effective substance abuse policy and practice. The purpose of this study was to provide surveillance information about the nature and extent of heroin use in South Africa. Data were collected from 41 specialist alcohol and other drug treatment centres in two metropolitan sites (Cape Town and Gauteng Province) between January 1997 and December 2003. Treatment indicators point to a substantial increase in heroin use over time. Most heroin users in treatment tend to be white, male, between the ages of 21 and 24 years and tend to smoke rather than inject the substance. However, this profile is changing. These emerging trends point to the possibility of heroin use becoming a serious health and social issue in South Africa and demonstrate the need for continued monitoring of heroin use patterns in the future and the development of a strategic plan for intervening before the situation deteriorates further.

Substance abuse, treatment needs and access among female sex workers and non-sex workers in Pretoria, South Africa

Background

This study examined cross-sectional data collected from substance-using female sex workers (FSW) and non-sex workers (non-SW) in Pretoria, South Africa, who entered a randomized controlled trial.

Methods

Women who reported alcohol use and recently engaging in sex work or unprotected sex were recruited for a randomized study. The study sample (N = 506) comprised 335 FSW and 171 female non-SW from Pretoria and surrounding areas. Self-reported data about alcohol and other drug use as well as treatment needs and access were collected from participants before they entered a brief intervention.

Results

As compared with female non-SW, FSW were found to have a greater likelihood of having a past year diagnosis of alcohol or other drug abuse or dependence, having a family member with a history of alcohol or other drug abuse, having been physically abused, having used alcohol before age 18, and having a history of marijuana use. In addition, the FSW were more likely to perceive that they had alcohol or other drug problems, and that they had a need for treatment and a desire to go for treatment. Less than 20% of participants in either group had any awareness of alcohol and drug treatment programs, with only 3% of the FSW and 2% of the non-SW reporting that they tried but were unable to enter treatment in the past year.

Conclusion

FSW need and want substance abuse treatment services but they often have difficulty accessing services. The study findings suggest that barriers within the South African treatment system need to be addressed to facilitate access for substance-using FSW. Ongoing research is needed to inform policy change that fosters widespread educational efforts and sustainable, accessible, woman-sensitive services to ultimately break the cycle for current and future generations of at-risk South African women.

Cocaine treatment admissions at three sentinel sites in South Africa (1997-2006): findings and implications for policy, practice and research

BACKGROUND

Accurate prevalence data on cocaine use, that points to where problems exist and the extent of these problems, is necessary to guide the formulation of effective substance abuse policy and practice. The purpose of this study was to provide surveillance information about the nature and extent of problematic cocaine use in South Africa.

METHODS

Data were collected between January 1997 and December 2006 on admissions for drug abuse treatment through a regular monitoring system involving 56 drug treatment centres and programmes in Cape Town, Gauteng Province (Johannesburg and Pretoria) and the Eastern Cape every six months as part of the South African Community Epidemiology Network on Drug Use (SACENDU). A one-page form was completed by treatment centre personnel to obtain demographic data, the patients' primary and secondary substances of abuse, the mode, frequency and age of first use of substance, and information on prior treatment.

RESULTS

Treatment indicators point to a significant increase in cocaine related admissions over time in all sites, but with substantial inter-site variation, particularly in recent years. The data indicate high levels of crack cocaine use and high levels of daily usage among patients, most of whom were first time admissions. Patients with cocaine related problems continue to be predominantly male, with a mean age of around 30 years. Substantial changes in the racial profile of patients have occurred over time. Poly drug use is high with cocaine often used with alcohol, cannabis and other drugs.

CONCLUSION

These trends point to the possibility of cocaine use becoming a serious health and social issue in South Africa and demonstrate the utility of continued monitoring of cocaine treatment admissions in the future. They also highlight the need to address cocaine use in national and provincial policy planning and intervention efforts. In terms of treatment, the findings highlight the need to ensure that treatment practitioners are adequately trained to address stimulant problems, poly drug use, and HIV and other risk behaviour related to crack cocaine use. Possible gaps in access to treatment by certain sectors of the population should be addessed as a matter of urgency.

Treatment for methaqualone dependence in adults

BACKGROUND

Methaqualone is a potent quinazoline, a class of sedative-hypnotics, that has a high potential for abuse. While the oral use of methaqualone (Quaalude, Mandrax) has waned in western countries since the mid-late 1980's, the practice of smoking methaqualone is a serious public health problem in South Africa, other parts of Africa and India. In the context of diminishing resources devoted to substance abuse treatment in regions affected by methaqualone abuse, it would be desirable to base treatment on the best evidence available. This review aimed to provide health care workers, policy-makers and consumers with the necessary information to make decisions regarding effective treatment of this highly dependence-producing drug.

OBJECTIVES

To compare the effectiveness of any type of pharmacological or behavioural treatment administered in either an in-patient or out-patient setting compared with either a placebo or no treatment or a waiting list, or with another form of treatment administered in either an in- or out-patient setting.

SEARCH STRATEGY

The authors searched the following databases: Cochrane Drugs and Alcohol Group'Register of Trials (February 2004); Cochrane Central Register of Controlled Trials (CENTRAL-The Cochrane Library, Issue 2, 2004); MEDLINE (OVID - January 1966 to february 2004), PsycInfo (OVID - January 1967 to february 2004). Relevant conference proceedings and reference lists of relevant articles were hand-searched. Broad internet searches were conducted and contact made with experts in the field.

SELECTION CRITERIA

All randomised controlled trials and quasi-randomised trials of the effectiveness of treatment programmes (in- or out-patient) for methaqualone dependence and abuse were considered for inclusion in this review.

DATA COLLECTION AND ANALYSIS

The authors independently assessed study eligibility and quality.

MAIN RESULTS

No studies were found that met the inclusion criteria.

AUTHORS' CONCLUSIONS

To date, no randomized controlled trials appear to have been conducted. Consequently, the effectiveness of inpatient versus outpatient treatment, psychosocial treatment versus no treatment, and pharmacological treatments versus placebo for methaqualone abuse or dependence has yet to be established.
