Abstract

Prematurity is a risk factor for elevated blood pressure (BP). We performed a mixed-methods study of care patterns and awareness of early BP screening recommendations for infants born prematurely (IBP) by interviewing/surveying providers on practice- and provider-level BP screening. IBP's records were reviewed for BP screening documentation, demographics, and gestational age (GA). Visits <33 months were reviewed for anthropometrics, BP, and comorbidities. Chi-square analysis evaluated BP screening by GA and comorbidities. Twenty-six of 49 practices completed interviews; 81% had infant BP equipment available; 4% had BP measurement protocol for IBP. Twenty-eight of 86 providers were aware of screening guidelines; none reported routine assessment. Twenty-eight of 118 IBP had >/=1 BP documented; 43% had BP >/=90th percentile. Screening did not differ by GA group. Kidney-related diagnosis was associated with more frequent BP screening (P = .0454). BP is not routinely measured though often elevated before age 3 in IBP.
