Introduction

•What is the aim of the session?• Effective communication and collaboration

•What will be covered in the session?• Journey so far

• Little but giant steps

Screening

• Screening is defined as:

“a public health service in which members of a defined population, who do not

necessarily perceive they are at risk of, or are already affected by, a disease or it’s

complications, are asked a question or offered a test to identify those individuals

who are more likely to be helped than harmed by further tests or treatment to

reduce the risk of disease or it’s complication”

Newborn Screening

Why screen newborns for sickle cell disease?

•Early administration of prophylactic penicillin markedly reduces the incidence of pneumococcal sepsis

•Clinical monitoring reduces morbidity and mortality

•Neonatal screening for β-thalassaemia major and other thalassaemias useful but less important

Newborn Screening: Outcome

Overall outcome to be achieved

• Mortality rate in children of under 5 of less than 2 deaths per 100 affected infants

Others

• Cascade family screening

• To target at risk families and offer future genetic choice

• To allow better Health Service resource planning

Kaduna Sickle Cell Screening Programme – The ideal

1) Antenatal Screening Programme

AIM: Identify mothers at risk of having an affected fetus

-High Prevalence (fetal prevalence SCD ≥1.5 / 10,000 pregnancies)

-Low Prevalence (fetal prevalence SCD <1.5 / 10,000 pregnancies)

2) Newborn screening Programme

-Universal

AIM: identify babies affected by SCD

3) Prenatal Diagnosis and DNA diagnostic services

AIM: To give a definitive diagnosis

Ongoing

▪ Regular training workshops

▪ Policy review and updating

▪ Incident reporting and review

▪ Collection and review of key performance indicators

▪ Linking newborn and antenatal screening results

▪ Newborn outcomes project

Successes

• Government support and program approval• MoU between SCORE and KDSG

• Academic and other partner support (BDTH, KASU, ABU, ABUTH, MOH, SPHCDA, FantsuamFoundation, SSCF)

• ASH CONSA support

• ARISE Exchange/RCPAth LabSkill Africa Standardization of diagnosis and care

• Use of tools in management

Futuristic

• Ability to design a framework of inter-agency and intra-agency collaboration

• Being ready for partnership and collaboration (ASH education programme, BSH, Academic institution)

• Influencing national decision on guidelines for care of the sickle

• Develop framework/curriculum for holistic sickle care (Genetic counselling, school screening, pre-marital counselling)

• To use framework in standardizing care of other genetic disorders

Policy Framework

“There is no passion to be found playing small - in settling for a life that is less than

the one you are capable of living.”
