Theoretical Examination of Pain Undertreatment in Nigerian Hospitals: A Critical Ethnography of Clinical Practice, Institutional Culture, and Policy Failure

Undertreated pain is a pervasive and ethically significant problem in Nigerian hospitals, affecting surgical, oncological, obstetric, and palliative patients, yet the institutional mechanisms, clinical culture norms, and policy failures that sustain this practice have never been subjected to critical theoretical scrutiny at the level of the health system. This study theorises pain undertreatment in Nigerian hospitals through a critical ethnography conducted across six hospitals in four geopolitical zones over 24 months of embedded fieldwork. The ethnographic design includes prolonged participant observation in surgical wards, oncology units, and emergency departments, accumulating over 1,800 field observation hours. Semi-structured interviews are conducted with 200 clinicians, nurses, pharmacists, hospital administrators, and patients. Regulatory documents, opioid procurement records, and prescribing data are analysed alongside field notes. Critical Discourse Analysis is applied to institutional communications and national drug policy documents. Foucauldian power analysis, Critical Medical Anthropology, and the Social Construction of Pain Theory provide the multi-theoretical analytical framework. The study's original contribution is a theoretically grounded Institutional Pain Undertreatment Model that situates clinical practice within structural opioid availability constraints, regulatory stigmatisation, professional culture, and patient literacy factors unique to the Nigerian context. Findings will provide a comprehensive evidence base for advocacy targeting opioid policy reform, clinical pain education, and nursing empowerment for pain reassessment.
