Parental psychological distress has been identified as a predisposing factor in attendance at and the inappropriate use of hospital pediatric emergency departments (PEDs). The aim of the study was to validate the Parental Stress Scale (PSS), a 12-item Spanish scale, in parents seeking care at PEDs. The study involved 270 participants with a mean age of 37.9 (SD = 6.76) years, of which 77.4% were women. The properties of the PSS were analyzed. The scale showed adequate internal consistency for the different factors (0.80 for the “Stressors” factor and 0.78 for the “Baby’s Rewards” factor) and optimal model fit (chi-square = 107.686; df = 53; CFI = 0.99; TLI = 0.98; RMSEA = 0.028; 90% CI = 0.00–0.05). The 12-item Spanish version of the PSS is a valid and reliable instrument for assessing the stress levels of parents seeking care in PEDs.

Background: Overcrowding in emergency services (ESs) is an escalating issue in many countries worldwide, and it is also evident in the paediatric context. Specifically, in paediatric emergency departments (PEDs) in Europe, there has been a noticeable upward trend in demand for care over the past decade, peaking at 9.1 million visits in 2020. Objectives: To identify interventions aimed at reducing non-urgent presentations (NUPs) and attendance rate PEDs. Methods: A systematic review of the last five years was conducted using various databases (Web of Science, PubMed, Scopus, and CINAHL) in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Results: A total of 15 articles were included in the final review, detailing five types of interventions: (1) telemedicine-based interventions, (2) the continuity of care interventions, (3) health literacy-based interventions, (4) interventions focused on establishing a point of access prior to emergency care, and (5) multidisciplinary interventions. Conclusions: The results of this review suggest the implementation of telemedicine-based interventions, the promotion of continuity of care, and the enhancement of parental health literacy as strategies to address the issue of overcrowding in PEDs.
