1/200 of us is born with
congenital heart disease…
A child is born in the US every
7.6 seconds…
1/10 extended families…
1 million ACHD survivors
A child with CHD is born in the US every
26 minutes…

CHD – Paradigm Shift
• 40,000 infants born with CHD/ year
• What is successful outcome?
– Surviving initial surgical repair
– Surviving to 1 year of age
– Normal childhood
– Normal adolescence
Surviving to / through Adulthood

CHB Transitioning Working
Group
• 30 clinicians throughout CHB representing all
outpatient clinics
• Numerous focus groups to identify key
transitioning education areas that are common
to a wide spectrum of pediatric diseases
• Established Goals
– 1). Assess the current state of preparing patients at
CHB for self-care in adulthood.
Current Practices for the Transition and
Transfer of Patients with a Wide Spectrum of
Pediatric-Onset Chronic Diseases
(Fernandes et al. 2011 Int Journal of Adol and Child Health)
• Single Center- CHB
• Random sample of 479 outpatient clinicians
• Overall response rate: 76.8% (368/479),
329/368 meet inclusion criteria

143 Physicians
157 Nurses/nurse practitioners
75 Social workers
26 Physician assistants
Table 1. Clinician Characteristics
(Fernandes et al. 2011 Int Journal of Adol and Child Health)
Transitioning Education
• 73% of clinicians stated their patients receive
transitioning education

71% Physicians
75% Nurses/Nurse Practitioners
80% Physician Assistants
60% Social Workers
• 92% provide transitioning education informally
• 61% begin transitioning education before age 16
years
(Fernandes et al. 2011 Int Journal of Adol and Child Health)
Perceptions of Transitioning and Transfer:
Results of a Survey of CHB Cardiology
Clinicians
• 31 Clinicians (16.9±9.7 years in practice)
– 16 MD
– 15 Nurses, NP’s, PA’s
• All cardiology clinicians stated that their
patients are provided with this
education/assessment
– 74.2% informally
– 22.6% checklist
– 13.0% unknown
Patient and Parent Perceptions of
Transitioning and Transfer @ CHB
• Recruitment of 16-25 year old patients with
pediatric onset disease likely to require life
long medical care and their parents
• 166 Patients
• 104 Parents
– 93 Matched Patient/Parent
Patient and Parent Perceptions of Transitioning
and Transfer in Cardiology @ CHB
• 30 Patients CHB Cardiology
– Mean age 19.5±3.0 years
– 14 Complex
– 6 Moderate
– 1 simple
– 2 HCM
– 3 CVG clinic
– 4 cardiac transplant
Transitioning EducationResources
• 90% of clinician’s support resources for the
development of transitioning education
programs
• 73% of parents identified the need for such
programs.
Parental Knowledge of LLCCC
• Multi-center study of 500 Parents

• 9 U.S. Centers
• Pediatrics, 2011 Nov 28 (Epub)

Key Findings
① The overwhelming majority of clinicians
believe they are providing their patients with
the necessary skills to become independent
adults capable of self care, although
informally.
① Patients and parents perceive such as
severely lacking.
① Clinicians, patients and parents
overwhelmingly support the need for
resources to improve the delivery of this type
of education.
