Unveiling the Drivers of Antibiotic Misuse in South African Primary Care

In South Africa, primary healthcare (PHC) facilities serve as the first line of defense for millions seeking treatment for common ailments. However, a groundbreaking study published in Frontiers in Pharmacology has shed light on a critical issue fueling antimicrobial resistance (AMR): inappropriate antibiotic use. Titled "Factors associated with inappropriate antibiotic use in South African communities: findings from the CAMUS survey," this research reveals that misconceptions, social norms, and low health literacy are key culprits behind misuse in PHC settings.

The study, conducted by researchers from Sefako Makgatho Health Sciences University (SMU), University of Pretoria (UP), and Cape Peninsula University of Technology (CPUT), surveyed 1,283 adult patients across 25 public PHC facilities in two provinces. Using the validated Community Antimicrobial Use Scale (CAMUS) and Health Literacy Test, it quantified misuse patterns and identified independent factors via multivariable logistic regression.

The Alarming Prevalence of Misuse

A staggering 76.5% of participants believed antibiotics could treat colds and influenza—viral infections where they are ineffective. Nearly one-quarter reported non-prescribed use, with community pharmacies as the primary source (81.7%). This aligns with broader trends where antibiotics are prescribed in up to 87% of PHC visits, often unnecessarily.

In rural areas, similar patterns emerge: 78.7% of antibiotics dispensed without prescription, mainly for self-perceived sexually transmitted infections (STIs). Overprescribing rates reach 45.4% in private primary care, with only 8.8% deemed fully appropriate.

Key Factors Driving Inappropriate Prescribing

The CAMUS analysis pinpointed social norms and inadequate health literacy as strongest predictors. Patients with low health literacy were 13.86 times more likely to seek non-prescribed antibiotics (aOR=13.86, 95% CI: 2.60–73.93). Permissive family and community expectations pressure prescribers, while easy pharmacy access bypasses oversight.

• Social Norms: Expectations from patients and families favor antibiotics for quick relief.
• Health Literacy Gaps: Misunderstanding differentiates bacterial vs. viral infections.
• Pharmacy Practices: Over-the-counter dispensing without prescription.
• Prescriber Pressures: Time constraints and financial incentives in private sector.

These factors echo earlier studies showing patient demand and provider habits as major contributors.

The Devastating Impact of AMR in South Africa

AMR claims thousands of lives annually in SA. In 2021, 35,054 deaths were associated with bacterial AMR, including 8,485 directly attributable; children under 5 saw 5,003 associated deaths. By 2019 figures, 9,500 direct and 39,000 associated deaths highlight the crisis.

Economically, AMR burdens healthcare with higher treatment costs and productivity losses. Globally, hospital costs from antibiotic-resistant infections hit US$700 billion in 2019; SA faces similar strains amid high PHC reliance.

South African Universities at the Forefront of AMR Research

SA higher education institutions are pivotal. SMU leads with global AMR advocacy, including student researchers tackling resistance mechanisms. UP's Antimicrobial Stewardship Pharmacology Initiative trains prescribers and evaluates hospital programs.

CPUT contributes to surveys like CAMUS, while Wits University runs inpatient AMR burden studies, and UKZN's Antimicrobial Research Unit focuses on nurse roles in stewardship. These efforts develop curricula for pharmacy and medical students, the first undergraduate AMS program in SA.

National Strategies and Stewardship Progress

SA's National AMR Strategy Framework (2014-2024) promotes surveillance, stewardship, and awareness, aligning with WHO Global Action Plan. Recent AWaRe-based indicators assess PHC prescribing, rating 61 metrics appropriate for stewardship.

Initiatives include hospital AMS reducing consumption, with data-driven enhancements in 2026.

Actionable Solutions to Curb Misuse

• Enhance health literacy via community campaigns explaining viral vs. bacterial infections.
• Regulate pharmacy dispensing, train for symptomatic relief.
• Implement AMS in PHC with AWaRe tools and audits.
• University-led training for prescribers on evidence-based guidelines.
• Public-private partnerships for surveillance.

Case Studies Highlighting Real-World Challenges

In Cape Town Metro, primary care adherence to guidelines was low, with frequent prescriptions for upper respiratory infections. Rural Limpopo saw 78.7% non-prescribed antibiotics for STIs, underscoring access issues.

Private GPs prescribed inappropriately in 45.4% cases, driven by patient pressure.

Future Outlook: Research and Policy Convergence

With 2026 developments like faith-based AMR mobilization and advanced surveillance, SA is poised for progress. Universities must expand interdisciplinary research, integrating AI for prediction and training future stewards.
