Insights
Simplified echocardiographic screening for rheumatic heart disease in children takes varying times. A single-view exam is fastest at 1.2 minutes per child, crucial for large-scale screening feasibility.
Area of Science:
- Cardiology
- Public Health
- Pediatrics
Background:
- Rheumatic heart disease (RHD) is a major cause of cardiovascular death in low- and middle-income countries, impacting millions.
- Simplified screening protocols show promise for accurately identifying at-risk children.
- The time efficiency of RHD screening protocols is a critical, underexplored factor.
Purpose of the Study:
- To compare the time required for different echocardiographic screening strategies for rheumatic heart disease.
- To assess the feasibility of large-scale RHD screening based on examination time.
Main Methods:
- An observational study was conducted in school-based screening programs in Kenya and Cameroon.
- Three distinct echocardiographic screening strategies were compared.
- The time taken for each screening strategy was recorded.
Main Results:
- A total of 911 children were included in the study sample.
- Single-view screening averaged 1.2 minutes per child.
- Two-view screening averaged 2.1 minutes per child, and multi-view screening averaged 5 minutes per child.
Conclusions:
- Significant differences exist in the time needed for various RHD screening protocols.
- The time efficiency of screening is a key consideration for implementing large-scale, population-based RHD screening programs.
Background:
Rheumatic heart disease affects 33 million people in low and middle income countries and is the leading cause of cardiovascular death among children and young adults. Evidence increasingly supports that simplified screening protocols can identify at risk children with good accuracy. One of the more proximal and pragmatic hurdles that has not been completely explored is the time required for executing the screening exam.
Methods:
We conducted an observational study comparing three different echocardiographic strategies in four separate school-based screening programs in Kenya and Cameroon.
Results:
In a sample of 911 children, we found that a single-view screening strategy can be obtained in an average time of 1.2 min/child, the two-view in an average of 2.1 min/child, and multi-view in an average of 5 min/child.
Conclusions:
Our study demonstrates that there are significant differences in the time required to execute different screening protocols and is an essential consideration in the feasibility of large scale populations based rheumatic heart disease screening programs.
