Evaluation of the Pattern of Use of a Pediatric Emergency Department in Italy.

Objectives: The aim of this study was to evaluate access to a pediatric emergency department (PED) in a large hospital, in particular to estimate the prevalence of potentially avoidable accesses and the characteristics of return visits.

Methods: Clinical health records from the PED of San Gerardo Hospital, Monza, Italy, were retrospectively reviewed. The study population was composed of subjects younger than 18 years who attended the PED during the period from October 1, 2017, to November 30, 2017.Accesses were defined nonurgent if characterized by white or green triage codes and patient's discharge as the outcome and were defined potentially avoidable if nonurgent and with no diagnostic/therapeutic procedures performed except a visit by the ED pediatrician.Return visits were defined as accesses that occurred within 72 hours of the first index visit.

Results: A total of 2064 children and adolescents younger than 18 years had at least 1 ED attendance between October and November 2017, for a total of 2364 accesses.The most frequent diagnoses were upper respiratory tract infections (29.5% of accesses), followed by gastroenteritis (7.0%) and abdominal pain (7.0%). In all, 1810 accesses (88%) were classified as "nonurgent," and 1228 (60%) potentially avoidable, 373 of which were probably avoidable because they occurred when the primary care physician was available.The number of return visits was 98 (5% of the accesses): 74 were nonurgent, 31 of which potentially avoidable. On 17 occasions, both index and return visits were potentially avoidable.

Conclusions: We confirm that most of the accesses to a PED are nonurgent and potentially avoidable. Interventions are needed to improve the appropriateness of use of emergency services.
