Population, Policy and Practice

We are a multi-disciplinary group of researchers with an international reputation for population-level and clinical research that influences public health policy and practice.

Our aim is to promote the health of children and young people and the adults they will become through conducting research:

  • across the life course
  • on common, chronic and complex conditions, in addition to rare disorders
  • on defining and measuring what matters for children, young people and their families
  • recognising the wider contexts of children's lives

Using Linked Administrative Health Databases

Pia Hardelid's interests are in using linked administrative health databases to examine the epidemiology of respiratory tract infections in children, infant and child mortality and quality of care for children with chronic conditions.

She holds a postdoctoral fellowship from the National Institute for Health Research to determine whether influenza vaccines, antivirals and antibiotics can prevent hospital admissions in children.
