Trends in hospitalizations in congenital heart disease patients in France: A national PMSI database analysis

Introduction

Thanks to the progresses made in the management of congenital heart diseases (CHD), life expectancy of these patients has greatly improved, including those of patients with complex CHD. Epidemiology of this growing population is rapidly evolving. French data are needed to prepare each regional healthcare plan.

Objective

We aim to analyse national PMSI database to assess trends and projections.

Methods

We investigated the number of hospitalizations stay of children and adults with CHD over 10 years from 2013 to 2022 in France. Complexity of CHD was defined according to M3C classification.

Results/Expected results

Number of hospital stays of patients with CHD varied from 37,339 to 45,310 in total and from 9,320 to 11,006 for patients with complex CHD. Over 10 years, the latter represent 26.2% of all hospitalizations.

In children, it varied from 19,787 to 23,023 in total and from 5,714 to 6,987 for children with complex CHD. Over 10 years, the latter represent 30.6% of all hospitalizations. The number of neonates with CHD hospitalized is very stable over time ranging from 1380 to 1596. A similar trend is observed for children.

In adults with CHD, it increased continuously by 55.9% from 15,056 to 23,475 and from 3,564 to 4,294 for adults with complex CHD. Over 10 years, the latter represent 21.0% of all hospitalizations. There is an increase in hospitalizations in adults with CHD with a 5-year projection suggesting an increase up to 35%. In particular number of ACHD hospitalized for management of arrhythmia or for catheterization has almost doubled over 10 years (Figure 1).

Conclusion/Perspectives

Number of children with complex CHD seems to be very stable over time. On the other hand, there is a growing number of hospitalizations in adults with CHD. Next healthcare plan should contribute to develop facilities for the specific management of adults with CHD in these centres.
