Risk Factors Associated With Pressure Injury in Critically Ill Children With Congenital Heart Disease.

Background: Children with congenital heart disease have unique risk factors associated with the pathophysiology of an abnormal heart; hence, this population is most likely at increased risk of acquiring a pressure injury during hospitalization. Few studies have included patients with congenital heart disease or examined the factors unique to these patients.

Objective: To identify risk factors associated with pressure injury development in children with congenital heart disease.

Methods: This retrospective study used a convenience sample from hospital-acquired data at an urban, tertiary, free-standing children's hospital. Patients were admitted to the intensive care unit between 2011 and 2018 with a diagnosis of congenital heart disease. Chi-square analysis was done to compare risk factors between patients, and logistic regression analysis was used to predict the probability that a patient would acquire a pressure injury.

Results: Eighty-two (30.5%) of the 269 patients in this study acquired pressure injuries. Sixty-six patients with pressure injuries met the inclusion criteria for analysis; 82% of those patients had had corticosteroids prescribed, and 71% were receiving anticoagulants. The overall predictive model for acquiring a pressure injury indicated an odds ratio of 3.25 (95% CI, 1.58-6.65) with an anticoagulant and an odds ratio of 9.98 (95% CI, 4.68-21.3) with a prescribed corticosteroid (P < .001 for both factors). Inpatient mortality was significantly associated with pressure injuries.

Conclusions: Corticosteroid and anticoagulant use were contributing factors in the development of pressure injuries in children with congenital heart disease.
