40 years of impact: the British Paediatric Surveillance Unit (BPSU)

Dr Ifeanyichukwu Okike, Deputy Chair of the British Paediatric Surveillance Unit and honorary professor, provides insights into the profound impact of BPSU studies on child health over the past four decades. The discussion highlights how BPSU research has shaped health policy and clinical practice, with landmark studies influencing the utilization of liver centers, national screening programs for metabolic and endocrine disorders such as MCAD and congenital hypothyroidism, and patient safety initiatives—including investigations into the unexpected collapse of babies in postnatal wards. Dr Okike also discusses the critical role of BPSU studies during health emergencies, notably the COVID-19 pandemic, where findings informed public health messaging and management strategies. He acknowledges current challenges, including declining awareness among trainees and lower clinician response rates, and outlines ongoing efforts to embed BPSU participation in training curricula to sustain its legacy and maximize future impact. Dr Okike emphasizes the importance of translating research into policy to ensure that patients benefit directly from surveillance and research activities. This interview took place at the RCPCH conference 2025 in Glasgow, Scotland.
