Clinical Trial Summary

The aims of this collaborative, interdisciplinary research project are to understand and describe the psychological impact of the announcement of a rare, serious disease present since birth and detected in the context of the systematic neonatal screening (DNS), in terms of the parents' experience, but also on the part of the medical team, in order to improve its process and the support it provides for the announcement of the diagnosis.

Description:

In France, newborn screening for phenylketonuria (PKU) has been offered systematically, but not compulsorily, since 1970. This enables the disease to be treated at an early stage, with presymptomatic treatment. While treatment can significantly improve the prognosis of affected children, ensuring normal cognitive development without neurological sequelae, the announcement of the suspicion of the disease and confirmation of the diagnosis can be painful, even traumatic, for parents, due in particular to the very specific context of the DNS. The screening results are not available until 10 days after the baby's birth, and given the urgency of the treatment, the announcement is made by a telephone call to the families when they have already returned home with their asymptomatic newborn. This call was made by an unknown doctor from a center of reference or competence for rare diseases (in this case hereditary metabolic diseases, HMD), whom the parents did not know, and who asked them to come to his department as a matter of urgency. This disease is not visible at the time of diagnosis, although intoxication is already present. This research follows on from a pilot study2 which showed the traumatic nature of this call, which; for the families, means that in an instant they are thrust into the field of a rare, genetic and chronic disease; for the teams, means that the care relationship will continue until the end of the patient's adolescence. The aims of this collaborative, interdisciplinary research project are to understand and describe the psychological impact of the announcement of a rare, serious disease present since birth and detected in the context of the DNS, in terms of the parents' experience, but also on the part of the medical team, in order to improve its process and the support it provides for the announcement of the diagnosis.

The analysis will be carried out under the responsibility of the researcher, her thesis supervisor (Dr Marco Araneda, MCU / Université Paris-Cité) and her thesis co-supervisor (Pr Pascale de Lonlay, PU-PH / APHP and Université Paris-Cité).

1. Analysis of qualitative data :

The interviews with the parents, doctors and midwives will be transcribed and then analysed using NVivo® software based on grounded theory methodology.

2. Analysis of quantitative data :

The data from the socio-psychological questionnaire will be analysed using simple, multidimensional descriptive statistics.

We will carry out an analysis of variance with repeated measures (IES-R) (time 1, time 2) to estimate the impact of time and care on the level of anxietý. A probabilitý level of 5% (p ≤ 0.05) will be considered́ significant for the results of the statistical tests. Statistical calculations will be performed using SPSS v.24 software, R y Mplus v. 8.3 statistical software.
