Pediatric Blood Pressure Screening Practices in Canada: New Study Reveals Prevalence of Hypertension Among … – Medriva

A new study published in JAMA Network Open has shed light on the pediatric blood pressure (BP) screening practices in Canada, uncovering the prevalence of hypertension (HTN) among children, and the effectiveness of current hypertension guidelines. Led by senior author Rahul Chanchlani, MD, and his team, the study highlights a notable increase in pediatric blood pressure screening and hypertension prevalence after the introduction of the 2016 Hypertension Canada and 2017 American Academy of Pediatrics guidelines for pediatric hypertension.

The study, which involved 343,191 children and adolescents aged 3-17 years, discovered that the proportion of patients whose BP was documented at least once annually increased from 13.3% in 2011 to 20.2% in 2019. The results showcase a significant rise in the prevalence of hypertension among the participants, from 1.6% in 2011 to 8.2% in 2019. This rise in prevalence, coupled with increased BP screenings, reflects the influence of the new guidelines on clinical practice.

However, despite the introduction of the guidelines and the observed increase in BP screenings, the study found that follow-up by primary care physicians remained suboptimal. While there was a slight improvement in the documentation and follow-up of high BP measurements, these were still below the recommended levels, revealing gaps in clinical care.

One of the key insights from this study was the need to understand the role of pediatric subspecialists in hypertension management. As the studys authors noted, determining causality can be challenging based on the available data. However, the findings highlight the importance of better implementation and dissemination of the guidelines among primary care providers, signaling a need for improved awareness and adherence to the guidelines.

Interestingly, it was also noted that laboratory testing and prescribing decreased after the guidelines were published. While the reasons for this are not explicitly clear, it does raise questions about the influence of guidelines on clinical practice, and how they may be shaping pediatric hypertension care.

This study has important implications for the screening and management of pediatric hypertension. The findings indicate that while the new guidelines have had a positive impact on BP screening practices, there is still room for improvement, particularly in the areas of follow-up care and the role of pediatric subspecialists.

Moreover, this study emphasizes the importance of continued research into pediatric hypertension. As noted in a summary table provided by the University of Iowas Department of Pediatrics, understanding blood pressure values for different age groups and percentiles is crucial in the diagnosis, assessment, prevention, and treatment of pediatric hypertension. This, coupled with the exploration of new treatments such as zilebesiran, a small interfering RNA that has shown promise in lowering angiotensinogen levels and reducing blood pressure, underscores the need for ongoing research and innovation in this field.

In conclusion, while strides have been made in the screening and management of pediatric hypertension, there is a need for further improvements in clinical care and better adherence to guidelines. Continued research and innovation, coupled with better implementation of guidelines among primary care providers, hold the key to optimizing pediatric hypertension care in Canada and beyond.
