Children with special healthcare needs, children with complex chronic conditions, children with medical complexity-a syndrome with several names, is an expanding patient population and represents an increasing number of inpatient admissions and healthcare expenditures (1, 2). As their overall inpatient admissions increase, so too do these children represent an increasing proportion of PICU admissions (3). Said differently, the PICU of 2023 is quite different than the PICU your grandparents knew in 1980. Many of the techniques and workflows of the 80s are now irrelevant or counterproductive.For example, a routinely used severity of illness scoring system (i.e., Pediatric Risk of Mortality [PRISM] [4]) was developed in the 80s and while updates are done periodically, there are many reasons these systems should be revamped. A major reason is that mortality has declined significantly since the 1980s (5, 6). Derivative scores were designed to identify severity associated morbidities (7) but not to identify latent safety threats (8) or to specifically risk stratify an individual complex patient. In this issue of Pediatric Critical Care Medicine, Verlaat et al (9) provide a concrete example; digging one layer deeper they discovered worrisome patterns of potentially preventable safety issues associated with new morbidities.As PICU lengths of stays push well into double and even triple-digit days, often within a subpopulation of children who simply cannot be cared for outside of the critical care setting, severity of illness scores at the time of admission predict little of what is to come. While outcomes in aggregate may improve with the use of such systems (10), it behooves us who care for these children with medical complexity to ensure we equitably recognize and address the potentially unique safety challenges this population presents.The study by Verlaat et al ( 9) explores the role adverse events may play in mortality among patients stratified as low risk for mortality at the time of their PICU admission. These "low-risk non-survivors" have a higher occurrence of adverse events than their counterparts who survived. Strikingly, this cohort of patients identified as low-risk are overwhelmingly patients with underlying complex chronic conditions-93% of low-risk nonsurvivors fall into this category. Their length of stay was considerably longer, more needed mechanical ventilation, and their duration of ventilation was longer than their low-risk surviving counterparts. This group of patients begs two important questions: do we underestimate the risk of mortality in children of medical complexity, and do we underrecognize important safety threats in this population? Or as Eulmesekian (11) commented on this group's earlier work (12), "Nevertheless, the article leaves readers with a clear message, which, while not new, is relevant: low-risk patients with [chronic critical conditions] are frequent PICU flyers, they may get worse, they may need intubation, they may die, and as we are not
