Prevalence of malnutrition in pediatric pulmonary hypertension cohort and role for registered dietitian involvement
Abstract
IntroductionPediatric pulmonary hypertension (PH) is a serious condition with increased risk for malnutrition due to increased caloric needs and reduced energy intake. This combination of disease and dynamic elements make it particularly challenging to meet expected growth patterns. Pediatric PH patients require close monitoring and individualized nutrition interventions to best meet nutrient needs. The prevalence of malnutrition and effective nutrition interventions in pediatric PH has not been studied.MethodsUsing our electronic medical record (EMR) patient care dashboard, malnutrition prevalence was assessed by reviewing the active problem list of all active PH patients at our center. A chart review compared patients with diagnosed malnutrition in the EMR to those with malnutrition identified by a registered dietitian (RD) using a standardized tool. Chart reviews also assessed outcomes of RD interventions.Results195 patients were identified as active PH patients followed by our PH center during the study period (November 2021 to January 2023). Of these, 5% (10/195) had an ICD-10 code for malnutrition listed in their chart. However, upon further chart review of the remaining 185 patients, 22% (41/185) had malnutrition identified by a RD using Texas Children's Malnutrition Tool, totaling 51/195 (26%) malnourished patients. The PH RD saw 25/51 (49%) patients during PH clinic visits in the study period. At follow up visits (3–4 months after initial assessment), 56% (14/25) patients seen by the PH RD either improved or resolved their malnutrition status by z-score assessment.ConclusionMalnutrition is present in pediatric PH, although underappreciated and underdiagnosed. Managing malnutrition in pediatric PH requires close monitoring, multidisciplinary involvement, and individualized nutrition recommendations. This is best achieved by a dedicated PH RD who is familiar with the unique needs of this population and available to provide consistent nutritional assessments and interventions to reduce malnutrition in this population.
