Insights
Infants with congenital heart disease (CHD) are often diagnosed late, missing optimal surgical timing. Parental income, not sex or education, influenced diagnosis timing in this study.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease Research
- Public Health
Background:
- Congenital heart disease (CHD) is a leading cause of infant mortality.
- Timely treatment is crucial for improving outcomes in CHD patients.
- Understanding diagnostic delays is key to optimizing interventions.
Purpose of the Study:
- To determine the age of first CHD suspicion and diagnosis confirmation.
- To assess follow-up rates at post-diagnosis outpatient clinics.
- To investigate the influence of patient sex, parental income, and education on diagnosis timing.
Main Methods:
- Retrospective study conducted over five years (2000-2004).
- Data collected from 214 patients at Kenyatta National Hospital.
- Analysis of patient demographics and diagnostic timelines.
Main Results:
- Mean age at referral to a pediatric cardiologist was 16.9 months.
- Mean age for CHD confirmation via echocardiography was 18.6 months.
- Higher parental income correlated with earlier suspicion of CHD (9.5 months vs. 19.1 months).
Conclusions:
- Late diagnosis of CHD may impede optimal surgical intervention.
- Parental income significantly impacts the timing of CHD suspicion.
- Patient sex and parental education did not show a significant influence on diagnosis timing.
Background:
Congenital heart disease (CHD) is a significant cause of death amongst infants. The timing of treatment in relation to the natural history of the disease correlates with the treatment outcome.
Objectives:
To determine the age at first suspicion of CHD, the age at confirmation of the diagnosis of CHD and the percentage follow-up at the first post diagnosis out patient clinic and to determine the influence of patient's sex, parental income and parental education have on the MP.
Design:
A five year retrospective study.
Setting:
Kenyatta National Hospital between January 1st 2000 and December 31st 2004.
Subjects:
Two hundred and fourteen patients were studied.
Results:
The overall mean age at referral to a paediatric cardiologist was 16.9 +/- 24.4 months [n = 102]. The mean age at which CHD was confirmed by echocardiography was 18.6 +/- 25.6 months [n = 202]. The mean age at which CHD was first suspected in patients from the province with the highest parental income was 9.5 +/- 5.1 months [n = 6]. The mean age at which CHD was first suspected in patients from a province with a significantly lower parent income was 19.1 +/- 23.2 months [n = 22], (p = 0. 046). The mean age at which CHD was confirmed in referred male patients was 16.0 +/- 17.6 months [n=48] and the mean age at which CHD was confirmed in referred female patients was 18.8 +/- 21.7 months [n = 52] (p = 0.25).
Conclusion:
The mean age at referral to a paediatric cardiologist was 16.9 months. This suggests that a significant number of patients may miss the opportunity to have optimal surgical intervention. Parental income appears to influence the MP, however, the level of parental education and patient sex did not.
