Armando A1 - AB - Adolescence is a time of increased vulnerability to mental health conditions, which may necessitate hospitalization. This study sought to identify and characterize patterns of adolescent (re-)hospitalizations. The one-year (re-)hospitalization patterns of 233 adolescents were analyzed. The sequences of hospitalization and discharge was examined using cluster analyses. Results revealed five distinct (re-)hospitalization patterns or clusters: Cluster A represented brief hospitalizations with 56 cases (24.03%) averaging 7.71 days; cluster B consisted of repetitive short hospitalizations involving 97 cases (41.63%) with an average of 19.90 days; cluster C encompassed repetitive medium hospitalizations included 66 cases (28.33%) averaging 41.33 days; cluster D included long hospitalizations with 11 cases (4.72%) and an average of 99.36 days; cluster E depicted chronic hospitalizations, accounting for 3 cases (1.29%) with an average stay of 138.67 days. Despite no age-based differences across clusters, distinctions were noted in terms of sex, diagnoses, and severity of clinical and psychosocial difficulties. The study identified characteristics of both regular and atypical adolescent hospitalization users, emphasizing the distribution of hospitalization days and their associated clinical attributes. Such insights are pivotal for enhancing the organization of child and adolescent mental health services to cater to the growing care requirements of this age group.
