BACKGROUND: Anemia occurs frequently in critically ill patients and it can impact on long-term outcome more so after a critical illness. Very little data are available about anemia in pediatric critical care survivors. Recent randomized control trials in children support the use of restrictive transfusion strategy in critically ill children. OBJECTIVES: This study aims to estimate the prevalence of anemia in pediatric critical care survivors, its causative factors and impact of restrictive transfusion strategy on its resolution. PATIENTS AND METHODS: In this retrospective observational study, patients who got discharged from pediatric intensive care unit (PICU), their clinical course, serial hemoglobin (Hb) level, and transfusion history were collected. Patients were divided into two groups according to transfusion strategy (restrictive and liberal group). Patients with anemia were followed up and persistence of anemia was noted monthly. RESULTS: In 54 cases enrolled in the study, 35 children had anemia (prevalence 35/54 = 64.8%). Statically significant difference between anemic and nonanemic groups was found in terms of duration of PICU stay and development of infection and no significant difference in age, gender, diagnosis, and requirement of mechanical ventilation. Among the 35 anemic children, restrictive transfusion strategy was followed in 21 and in 14 children liberal transfusion strategy was followed. Ten children were lost to follow-up. Anemia got resolved in 18 children (18/25 = 72%) and 7 children (7/25 = 20%) had persistent anemia. Among 25 children, 4 children in restrictive group (4/15 = 26.6%) and 3 children in liberal group (3/10 = 30%) had persistent anemia (statistically not significant; P > 0.05). CONCLUSIONS: A large proportion of PICU survivor children is anemic at discharge, this could be due to long duration PICU stay or acquired infection during hospital stay or following restrictive transfusion strategy but on a long-term follow-up no statistically significant difference was noted between two groups.
