Background: Pediatric high blood pressure (BP) predicts future cardiovascular disease events. High BP is improperly measured, underrecognized, and undermanaged especially in disadvantaged populations. In a large, diverse, academic pediatric practice, we detail the associations of a comprehensive initiative with high BP provider recognition.
Methods: A comprehensive BP initiative was promulgated including (1) retraining providers and staff on BP management; (2) deploying equipment at 55+ sites; and (3) electronic decision support tool alerting staff and clinicians and suggesting management. During the 14-month preintervention and 14-month postintervention periods, data on BP and patient characteristics were collected. The outcome was incident BP recognition defined as any of the following: BP-specific International Classification of Diseases, Tenth Revision, diagnosis; problem list entry; specialty referral; diagnostic testing; repeat visit; or antihypertensives. Dichotomized as under versus at or over 13 years of age, analyses utilized interrupted time series and multivariable-adjusted logistic regression.
Results: From preintervention (children, n=105 674; adolescents, n=54 365) to postintervention (children, n=87 917; adolescents, n=56 470), the proportion measured with high BP declined in children and adolescents (30% versus 14% and 30% versus 15%, respectively, each P<0.001). Post-intervention, high BP provider recognition was 58% higher in children (4.6%-7.3%) and 43% higher in adolescents (7.9% versus 11.3%; P<0.001 for both). The improvement was not different in disadvantaged race, ethnicity, or zip codes.
Conclusions: A comprehensive BP initiative was associated with more appropriate high BP measurement and recognition including in disadvantaged populations. Future work may address the low overall and nonsustained recognition and consideration of electronic decision support for pediatric BP management and mitigating disparities.
