Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this prospective population-based study is to evaluate the new disease description and management guidelines for breath-holding spells in children (Hellström Schmidt et al, Acta Paediatrica 2024) below the age of 5 years in southern Sweden. The main questions it aims to answer are:

* Does the disease description and management guidelines lead to the expected reduction in diagnostic interventions and are the clinical managements guidelines safe to use?
* If iron supplementation is given, does it reduce the frequency and severity of the spells?
* What information and support does parents to children with breath-holding spells need?

Participants will undergo evaluation by a medical doctor and if typical breath-holding spells are diagnosed, be managed according to the new guidelines. If iron deficiency is found, iron supplementation is recommended. Digital surveys will be distributed and parents of patients with frequent spells will be eligible for participation in an interview sub-study.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

NON_RANDOMIZED

Intervention Model

PARALLEL

Inclusion upon suspicion of Breath Holding Spell. Thereafter, allocation to either the group that has a defined typical Breath Holding spell, or the alternative (parallel) group that is not diagnosed with a typical Breath Holding Spell. Subsequent management of study subject in the Typical Breath Holding Spell group according to the management algorithm.
Primary Study Purpose

DIAGNOSTIC

Blinding Strategy

NONE

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Typical spells

Patients with typical spells should be investigated according to our guidelines

Group Type OTHER

Guidelines

Intervention Type DIAGNOSTIC_TEST

Participant with typical spells will be investigated according to our guidelines. These include that participants with heredity for or signs and symptoms of cardiac disease will be subjected to an ECG and participants with two or more spells should be subjected to blood tests for anemia and iron deficiency

Non-typical spells

Patients with non-typical spells will be investigated individually, as it is done today

Group Type NO_INTERVENTION

No interventions assigned to this group
