Parental response to repeat testing of infants with 'false-positive' results in a newborn screening program
Insights
Many parents of infants undergoing repeat newborn screening for metabolic disorders lack clear information about abnormal initial results. Improved communication about screening significance can reduce parental concern, even with normal follow-up tests.
Area of Science:
- Medical Genetics
- Pediatrics
- Public Health
Background:
- Newborn screening programs are crucial for early detection of metabolic disorders.
- Accurate parental understanding of screening procedures, especially retesting, is vital for informed consent and reduced anxiety.
- Previous studies highlight communication gaps in healthcare settings.
Purpose of the Study:
- To assess parental understanding of newborn retesting for metabolic disorders.
- To evaluate the impact of initial abnormal test result awareness on parental anxiety.
- To identify factors contributing to parental concern during the screening process.
Main Methods:
- Survey of 60 parents of infants undergoing repeat newborn screening for metabolic disorders.
- Interviews conducted before and after repeat test results were known.
- Analysis of parental awareness of initial abnormal results and reported anxiety levels.
Main Results:
- 45% of parents understood retesting was due to an abnormal initial result; 55% had incomplete or incorrect information.
- Awareness of an abnormal initial result did not increase parental anxiety during retesting.
- Parental concern about infant health post-retesting was linked to insufficient information, not awareness of the initial abnormal result.
Conclusions:
- Parental comprehension of newborn screening retesting protocols requires improvement.
- Clear, sufficient information about the screening process and its health implications is essential to mitigate parental anxiety.
- Effective communication strategies are needed to support parents navigating newborn metabolic disorder screening.
Abstract:
Forty-five percent of the parents of 60 infants being retested in a newborn screening program for metabolic disorders understood that their infant was undergoing retesting because the first test result was abnormal. Fifty-five percent had incorrect or incomplete information, believing that retesting was routine, or that mistakes had been made in the original testing procedure, or they report being told nothing specific about the testing. Parents who were aware that the initial test was abnormal were no more anxious or depressed while waiting for the repeat test results than other parents. At a second interview after learning the normal results of the repeat test, both those parents informed of the initial abnormal result as well as those not informed were less anxious and depressed. However, 36% of the parents of these normal infants reported concern about the health of their infant because of the repeat testing. This concern was not related to a parent's knowledge that the initial test result was abnormal, but was greater in parents reporting that they had not received sufficient information about the screening/testing process and its significance for the health of their infant.
