Paediatricians and other child health professionals have a key role in identifying, preventing or mitigating the impacts of poverty on child health. Approaching a problem as vast and intractable as poverty can seem daunting. This article will outline how social determinants impact child health, and provide practical guidance on how to address this problem through a public health lens.

This article describes the rapid, system-wide reconfiguration of local and network services in response to the newly described paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS) (also known as multisystem inflammatory syndrome in children). Developing the model of care for this novel disease, whose natural history, characteristics and treatment options were still unclear, presented distinct challenges.We analyse this redesign through the lens of healthcare management science, and outline transferable principles which may be of specific and urgent relevance for paediatricians yet to experience the full impact of the COVID-19 pandemic; and more generally, for those developing a new clinical service or healthcare operating model to manage the sudden emergence of any unanticipated clinical entity.

Objectives: This study aims to review whether implementation of increased duration of consultant presence is associated with reduction in length of hospital stay (LoS) in children with an unplanned admission to hospital. METHOD DESIGN/SETTING/PARTICIPANTS/INTERVENTIONS/OUTCOME MEASURES: An observational before-and-after study of all unplanned general paediatric admissions to a UK hospital between 1 September 2012 and 31 August 2015, comparing LoS and readmission rates before and after implementation of a policy mandating consultant review within 12 hours of unplanned hospital admission.

Results: 5367 inpatient admissions were analysed: 3386 prior to implementation of the policy and 1981 afterwards.

Objective: To examine the contribution of recurrent admissions to the high rate of emergency admissions among children and young people (CYP) in England, and to what extent readmissions are accounted for by patients with chronic conditions.

Design: All hospital admissions to the National Health Service (NHS) in England using hospital episode statistics (HES) from 2009 to 2011 for CYP aged 0-24 years. We followed CYP for 2 years from discharge of their first emergency admission in 2009.

Education of health care professionals has given little attention to patient safety, resulting in limited understanding of the nature of risk in health care and the importance of strengthening systems. The World Health Organization developed the Patient Safety Curriculum Guide: Multiprofessional Edition to accelerate the incorporation of patient safety teaching into higher educational curricula. The World Health Organization Curriculum Guide uses a health system-focused, team-dependent approach, which impacts all health care professionals and students learning in an integrated way about how to operate within a culture of safety.

This review seeks to explore and explain what health policy research is and why it matters, through pooling the evidence and providing case examples. Alongside examining the types of research involved, and their rationale the paper identifies the challenges taking part in this sort of research may create. Finally the paper suggests how to make clinical research more accessible to policy makers.
