ethnic population

and sickle cell
National Policy

screening programme for
haemoglobinopathies and sickle cell
disease”
To be in place by 2004
Organisation of Services in
London

Neonatal programme (roll out 2003)
• Mixture of universal and selective screening
• Mixture of cord, capillary and dried blood spot screening
• Implications for laboratories service

Antenatal programme (roll out 4/04)
• Uses local laboratories
• Selective screening in some areas based on ethnicity
• Many areas already universal screening

Some hospitals have linked programmes
Methodology of Study

Information groups in acute trusts in London
• Haematologists, paediatricians, midwifery representatives,
haemoglobinopathy counsellors, obstetricians, GPs

Individual interviews
• voluntary groups, counsellors, genetic services,
independent hospitals and midwives

Models of good practice identified
Analysis of data

29 acute trusts in analysis

London-wide report based on questionnaire

Flow charts for acute trusts and key
recommendations at Strategic Health
