Summary

To address the knowledge gap that exists among providers resulting in underdiagnosis of chronic thromboembolic pulmonary hypertension (CTEPH), the investigators have devised this 400-patient single-center Quality Improvement Initiative in the form of a randomized controlled trial of an EPIC Best Practice Advisory (BPA) on-screen alert versus no notification to increase echocardiographic screening for CTEPH and the diagnosis of CTEPH in patients with prior pulmonary embolism (PE) and symptoms/signs suggestive of pulmonary hypertension or recent pulmonary testing suggesting unexplained respiratory symptoms at 3 months.

Aim #1: To determine the impact of a Best Practice Advisory (BPA), using the EPIC Electronic Health Record computerized decision support (CDS) software, on echocardiographic screening for CTEPH in patient with prior PE and symptoms/signs suggestive of pulmonary hypertension or recent pulmonary testing suggesting unexplained respiratory symptoms.

Aim #2: To determine the impact of an EPIC BPA on the diagnosis of CTEPH in patient with prior PE and symptoms/signs suggestive of pulmonary hypertension or recent pulmonary testing suggesting unexplained respiratory symptoms.

Description

Study design: 400-patient single-center Quality Improvement Initiative in the form of a randomized controlled trial. The allocation ratio will be 1:1 for an EPIC Best Practice Advisory (BPA) on-screen alert versus no notification. Investigators will be assessing the impact of the EPIC BPA on echocardiographic screening for chronic thromboembolic pulmonary hypertension (CTEPH) and the diagnosis of CTEPH in the patients enrolled in this Quality Improvement Initiative. While investigators will randomize patients by Attending Physician of Record to minimize cluster-effect, the observational unit will be the patient.

Type of control : The control group will have no electronic alert notification issued to the responsible provider.

Number of subjects: 400 subjects will be enrolled with 200 subjects to be randomized to the alert group and 200 subjects to the control group in a 1:1 allocation ratio.

Primary Efficacy Outcome: Frequency of echocardiographic screening for CTEPH in patients with prior pulmonary embolism (PE) and symptoms/signs suggestive of pulmonary hypertension or recent pulmonary testing suggesting unexplained respiratory symptoms at 3 months. Investigators will review the order entry and cardiology test results sections of the Electronic Health Record (EPIC) to make this determination.

Secondary Efficacy Outcome: Frequency of CTEPH diagnosis at 3 months. The diagnosis of CTEPH will be confirmed by clinical notation in the EHR or a mean pulmonary-artery pressure greater than 25 mmHg that persists 6 months after PE diagnosis.

Safety Outcomes: Because there is no reasonable expectation for adverse events or patient safety concerns with this Quality Improvement Initiative focused on increasing provider awareness about the risk of CTEPH and the indication for screening with echocardiography, investigators will not collect any safety outcomes or variables.

Plan for statistical analysis: The primary statistical analysis will be the comparison of the frequency of echocardiographic screening for CTEPH in the alert group compared with the control (no alert) group. A secondary statistical analysis will be the comparison of the frequency of CTEPH diagnosis in the alert group compared with the control (no alert) group.
