Although the global burden of ear, nose and throat (ENT) diseases is high, data relating to ENT disease epidemiology and diagnostic error in resource-limited settings remain scarce. We conducted a retrospective cross-sectional review of ENT patients’ clinical records at a resource-limited tertiary hospital. We determined the diagnostic accuracy and appropriateness of patient referrals for ENT specialist care using descriptive statistics. Cohens kappa coefficient (κ) was calculated to determine the diagnostic agreement between non-ENT clinicians and the ENT specialist, and logistic regression applied to establish the likelihood of patient misdiagnosis by non-ENT clinicians. Of the 1543 patients studied [age 0–87 years, mean age 25(21) years (mean(SD)], non-ENT clinicians misdiagnosed 67.4% and inappropriately referred 50.4%. Compared to those aged 0–5 years, patients aged 51–87 years were 1.77 (95%CI: 1.03–3.04) fold more likely to have a referral misdiagnosis for specialist care. Patients with ear (aOR: 1.63; 95% CI: 1.14–2.33) and those with sinonasal diseases (aOR: 1.80; 95% CI: 1.14–2.45) had greater likelihood of referral misdiagnosis than those with head and neck diseases. Agreement in diagnosis between the ENT specialist and non-ENT clinicians was poor (κ = 0.0001). More effective, accelerated training of clinicians may improve diagnostic accuracy in low-resource settings.

Background While ear, nose, and throat (ENT) diseases are a substantial threat to global health, comprehensive reviews of ENT services in Southern Africa remain scarce. Objective This scoping review provides a decade-long overview of ENT services in Southern Africa and identifies gaps in healthcare provision. From the current literature, we hope to provide evidence-based recommendations to mitigate the challenges faced by the resource-limited ENT service. Data Sources PubMed, Web of Science, EBSCOhost, Cochrane Library, Cochrane Library, and Scopus. Review Methods On several databases, we conducted a comprehensive literature search on both quantitative and qualitative studies on ENT services in Southern Africa, published between 1 January 2014 and 27 February 2024. The extracted data from the analyzed studies was summarized into themes. Results Four themes in the fourteen studies included in the final analysis described the existing ENT services in Southern Africa: 1. Workforce scarcity and knowledge inadequacies, 2. Deficiencies in ENT infrastructure, equipment, and medication, 3. Inadequate ENT disease screening, management, and rehabilitation and 4. A lack of telehealth technology. Conclusion The Southern African ENT health service faces many disease screening, treatment, and rehabilitation challenges, including critical shortages of workforce, equipment, and medication. These challenges, impeding patient access to ENT healthcare, could be effectively addressed by implementing deliberate policies to train a larger workforce, increase ENT funding for equipment and medication, promote telehealth, and reduce the patient cost of care.
