Abstract The 2017 Sierra Leone National Nutrition Survey reported poor practice regarding the medical management of severe acute malnutrition and the provision of emergency food to patients, particularly in the northern city of Makeni. We developed a training package for paediatric nurses, aiming to design an easily reproducible format which could be utilised nationally. Our aims were to empower and educate staff to provide more consistent care by challenging the negative cultural perception of malnourished patients and increasing knowledge of key guidelines. A two-day course based around UNICEF guidance on malnutrition was developed with the financial support of the Sierra Leonean office of the World Health Organisation. We sought the advice of local staff on issues impacting the quality of malnutrition care, including cultural barriers, educational limitations and supply issues. Lectures and practical sessions were devised covering recognition, assessment and management. Communication skills were taught using role play, focussing on the key role of nurses in parental education, and nursing skills were reinforced using practical tasks. Local staff identified for their strong teaching and leadership were recruited as instructors and to provide feedback on session design and content. 21 candidates attended from across the region, with the majority based in inpatient feeding units. Candidates completed a pre- and post-course written examination and a qualitative feedback form. Pre-course exam results ranged from 35%-85% with an average of 65%; post-course results showed improvement with a range of 55%-100% and an average of 88%. Candidates rated the course on average 9.7 out of 10 and the written feedback was positive. We subsequently observed positive changes in clinical practice in the inpatient feeding units across the region. Based on these assessments the course achieved its aims. Further study is needed to know if noted clinical improvements were sustained. Key messages • Challenging local cultural perceptions of malnourished patients is crucial to establishing improvement in medical care for this group. • Sustainable educational intervention requires local instructors who can independently deliver teaching, and establishing this cohort at the course inception is critical to its ongoing success.
