Predicting Delayed Shock in Multisystem Inflammatory Disease in Children: A Multicenter Analysis From the New York City Tri-State Region

OBJECTIVES

Patients with multisystem inflammatory disease in children (MIS-C) are at risk of developing shock. Our objectives were to determine independent predictors associated with development of delayed shock (≥3 hours from emergency department [ED] arrival) in patients with MIS-C and to derive a model predicting those at low risk for delayed shock.

METHODS

We conducted a retrospective cross-sectional study of 22 pediatric EDs in the New York City tri-state area. We included patients meeting World Health Organization criteria for MIS-C and presented April 1 to June 30, 2020. Our main outcomes were to determine the association between clinical and laboratory factors to the development of delayed shock and to derive a laboratory-based prediction model based on identified independent predictors.

RESULTS

Of 248 children with MIS-C, 87 (35%) had shock and 58 (66%) had delayed shock. A C-reactive protein (CRP) level greater than 20 mg/dL (adjusted odds ratio [aOR], 5.3; 95% confidence interval [CI], 2.4-12.1), lymphocyte percent less than 11% (aOR, 3.8; 95% CI, 1.7-8.6), and platelet count less than 220,000/uL (aOR, 4.2; 95% CI, 1.8-9.8) were independently associated with delayed shock. A prediction model including a CRP level less than 6 mg/dL, lymphocyte percent more than 20%, and platelet count more than 260,000/uL, categorized patients with MIS-C at low risk of developing delayed shock (sensitivity 93% [95% CI, 66-100], specificity 38% [95% CI, 22-55]).

CONCLUSIONS

Serum CRP, lymphocyte percent, and platelet count differentiated children at higher and lower risk for developing delayed shock. Use of these data can stratify the risk of progression to shock in patients with MIS-C, providing situational awareness and helping guide their level of care.

Pediatric ED departmental complexity: a different approach to the concept of ED crowding

OBJECTIVE

Emergency department (ED) crowding is a significant problem in Canada and internationally and is associated with the potential for patient harm. Although pediatric patients represent a significant proportion of overall ED visits, there is limited research on pediatric ED crowding. The Canadian Association of Emergency Physicians defines department crowding as a mismatch between the required and available resources to provide timely emergency care. We propose that rather than crowding, it is better to think of ED patient populations as being more or less "complex" as defined by proxies of the human and physical resources needed for patient management. The study objectives are to explore the utility of a simple and easily available retrospective metric of ED complexity, and to assess the relationship this measure has on patient outcomes in a pediatric ED.

METHODS

Using administrative data from a tertiary care pediatric ED, we developed a departmental complexity score based on patient registration number, triage acuity, and departmental length of stay as a proxy for the resources necessary to provide ED care. We then explored the relationship between this departmental complexity score and clinical care indices.

RESULTS

The score shows a strong relationship with the number of patients who left without being seen by a physician, as well as time to initial MD assessment, both measures which have been used to represent ED crowding in previous research. We found no association between our departmental complexity score and adverse impacts on patient care outcomes of hospital admission, pediatric ICU admission, or patients returning to the ED within 72 h of leaving.

CONCLUSIONS

The departmental complexity score has promise as a retrospective measure of departmental resource requirement and may have a role in the ongoing assessment of patient flow.
