Trial Outcomes & Findings for Electronic Health Record-Based Clinical Decision Support to Improve Blood Pressure Management in Adolescents (NCT NCT01760239)

NCT ID: NCT01760239

Last Updated: 2019-10-22

Results Overview

Clinical recognition of hypertension as determined by one or more of the following; 1) hypertension or elevated BP as discharge diagnosis, 2) hypertension or elevated BP in the clinical note, 3) hypertension or elevated BP in discharge instructions, 4) hypertension or elevated BP added to the problem list.

Participant Flow

Primary care providers (physicians, physician assistants,nurse practitioners) as of April 2014 were eligible. Providers received a letter inviting them to complete surveys (pre and post intervention). Completing surveys was considered implied consent. Patient consent was waived as no direct contact between patients and study team occurred.

31,579 patients 10-17 years of age with \>=1 BP measurement were assessed for eligibility for the primary analysis. After excluding for non-incident hypertension, and restricting to patients with BPs at \>=3 visits with BP \>=95th percentile who meet case definitions for new onset hypertension, the analytic denominator equals 522.

Measure
Clincal Decision Support (CDS)
The Clinical Decision Support (CDS) tool will be activated when a BP is entered in the vital sign section of the electronic health record (EHR). Data is exchanged between the EHR and the CDS that runs the data through algorithms and returns a response with appropriate action to the EHR. The CDS tool, includes six key features: (i) prompts regarding the need for height data to classify the BP by percentile (ii) prompts to repeat any BP that is ≥90% or ≥120/80 mm Hg (iii) classification of BPs by percentile, including classification of those in pre-hypertension, stage 1 hypertension and stage 2 hypertension range (iv) review of previous hypertension diagnoses and BPs in order to classify elevated BPs as incident (first or second elevated BP) or persistent (third or greater elevated BP) (v) tailored CDS based on hypertension category and previous diagnoses (vi) graphical representation of current and historical BP data by age and BP percentile.
Control
Patients in this group will receive usual care from their clinic. The CDS tool will not be activated.

PRIMARY outcome

Timeframe: 6 months

Population: The sample was restricted to patients with blood pressures at \>=3 visits with blood pressure \>=95th percentile, who were then passively monitored for study endpoints. Patients with a previous hypertension diagnosis were excluded.

Clinical recognition of hypertension as determined by one or more of the following; 1) hypertension or elevated BP as discharge diagnosis, 2) hypertension or elevated BP in the clinical note, 3) hypertension or elevated BP in discharge instructions, 4) hypertension or elevated BP added to the problem list.
