Breakthrough Findings from South African Hospitals
A groundbreaking study published in The Lancet Regional Health – Africa has demonstrated the effectiveness of a simple yet powerful four-element bundle for perioperative pain management in South Africa. Led by researchers from leading universities including the University of Cape Town and Stellenbosch University, the registry-based quality improvement initiative involved 3,522 patients across ten diverse hospitals. This research addresses a critical gap in postoperative care, where moderate to severe pain affects up to 80% of surgical patients in resource-limited settings like South Africa.
The study, titled "Evaluating a perioperative pain management bundle in South Africa: a registry-based quality improvement study," utilized the internationally validated PAIN OUT registry to capture patient-reported outcomes on postoperative day one. Implementation of the bundle increased from just 9.2% at baseline to 39.1% post-intervention, leading to significantly better pain control, reduced interference with daily activities, and higher patient satisfaction.
Understanding Perioperative Pain in the South African Context
Perioperative pain refers to pain experienced by patients before, during, and after surgery. In South Africa, where surgical volumes are rising to meet global health goals outlined by the Lancet Commission on Global Surgery, inadequate pain management remains a persistent challenge. Studies show that 62-82% of postoperative patients experience moderate to severe pain, contributing to prolonged hospital stays, increased complications, and chronic pain development.
Resource constraints in public hospitals—staff shortages, limited training, and inconsistent guideline adherence—exacerbate the issue. The African Pain Research Initiative, spearheaded by University of Cape Town's Professor Romy Parker, has long advocated for patient-centered approaches. This bundle study builds on prior PAIN OUT data, proving that low-cost, adaptable interventions can yield measurable improvements even in district and tertiary facilities serving low-income populations.
Pain not only causes suffering but also hampers recovery: it interferes with breathing, mobility, sleep, and raises risks of infections and thromboembolism. By prioritizing pain as a quality metric, South African healthcare can align with ethical standards and enhance surgical outcomes.
🩹 The Four Elements of the Perioperative Pain Management Bundle
The bundle comprises evidence-based, easy-to-implement components tailored for local contexts:
- Patient Education: Informing patients preoperatively about pain expectations, reporting strategies, and non-drug techniques like relaxation or positioning.
- Intraoperative Techniques: Use of local/regional anesthesia (e.g., nerve blocks) or wound infiltration to minimize systemic analgesics.
- Non-Opioid Analgesics: Administering full daily doses of 1-2 non-opioids (e.g., paracetamol, NSAIDs) starting intraoperatively.
- Postoperative Assessment: Routine pain scoring with reassessment and goal-directed treatment adjustments.
Multidisciplinary teams—including anaesthetists, nurses, physiotherapists, and pharmacists—adapted delivery via micro-teachings, posters, and workflow integration. Opioids were rescue-only, promoting opioid-sparing care amid global concerns.
Study Design and Participating Institutions
Conducted as a pre-post observational study, baseline data from 1,808 patients preceded bundle training and rollout, followed by 1,714 post-implementation cases. Data came from obstetrics/gynaecology (49%), orthopaedics/traumatology (39%), and general surgery (13%), reflecting common procedures like caesareans and fracture repairs.
Hospitals spanned public district, academic tertiary (e.g., Groote Schuur linked to UCT), and private sectors, showcasing versatility. Universities played pivotal roles: UCT's Anaesthesia and Perioperative Medicine Department coordinated; UKZN, Stellenbosch, and Wits provided investigators. This collaboration underscores higher education's leadership in translating research to practice.
The PAIN OUT registry ensured standardized, anonymous PRO collection via the International Pain Outcomes Questionnaire in multiple languages, including isiXhosa and isiZulu.
Key Results: Dramatic Improvements in Pain Outcomes
Full bundle compliance quadrupled, with each element rising significantly (e.g., non-opioid use from 34% to 62%; patient info from 53% to 75%). Patients receiving all four elements scored 2.4 on the Composite Pain Score (CPS, 0-10 lower better) versus 3.4 for 0-1 elements—a clinically meaningful small-to-medium effect (SMD -0.36, p<0.001).
- Pain Severity: 3.6 vs 4.9
- Pain Interference: 2.2 vs 3.3
- Side Effects: Non-significant but trending better (1.4 vs 2.0)
Regression confirmed dose-response: more elements, better outcomes. Patient education emerged strongest, followed by non-opioids and infiltration. Routine reassessment was crucial; without it, benefits waned.

Patient Perspectives and Satisfaction Gains
Beyond scores, patients reported less desire for additional treatment and higher satisfaction. In resource-limited wards, where nurse-to-patient ratios strain care, the bundle empowered self-management and streamlined interventions. Qualitative feedback highlighted feasibility: teams valued visual aids and feedback loops.
This aligns with prior SA audits showing 65-80% pain prevalence post-caesarean or orthopaedic surgery. By measuring PROs, the study made pain "visible," shifting from reactive to proactive care.

South Africa's public hospitals face staffing shortages, formulary limits, and high patient loads—mirroring LMIC hurdles. Yet, bundle uptake succeeded via local adaptation: no new resources needed, just reprioritization. Training took minutes per staffer; digital prompts sustained change.
Barriers like low health literacy were tackled head-on with multilingual materials. This contrasts global trends where pain remains under-assessed in 50-70% of cases.
Universities like UCT, with Prof. Parker's Pain Management Unit, bridged academia-clinic gaps through capacity building.
Implications for South African Medical Education and Training
This study spotlights higher education's role: investigators from UCT, UKZN, SU, and Wits trained teams, integrating quality improvement into curricula. Future doctors, nurses, and physiotherapists must master bundles for opioid-sparing, equitable care—key for National Health Insurance goals.
Training programs could embed PAIN OUT tools, fostering research literacy. For aspiring professionals, opportunities abound in university jobs advancing pain science.
Broader Impacts and Scalability Across Africa
Aligning with Lancet Commission calls, the bundle supports surgical expansion without added suffering. Cost-effective (prior analyses show savings via shorter stays), it's scalable via networks like PAIN OUT Africa.
Potential: Reduce chronic pain risk (10-50% postop cases), boost mobility, cut readmissions. Policymakers could mandate bundles in surgical protocols.Read the full Lancet article.

Future Directions and Calls to Action
Next: Longitudinal tracking, bundle evolution (e.g., digital apps), pan-African rollout. Universities should lead RCTs, train via simulations.
