Quality of Care in AS IMPULSE Study


Brief description of study

The purpose of this study is to narrow the gap between patients being diagnosed with severe aortic stenosis and those being appropriately monitored and treated. For this purpose a prospective survey of current practice (3 months) will be conducted followed by a six month period of intervention during which a variety of quality improvements measures will be implemented. There will then be a 3 month follow-up period during which the legacy of this initiative will be monitored during which no intervention will be carried out.

Detailed Study Description

All patients meeting pre-specified criteria (severe aortic stenosis whether with or without symptoms) will be collected. There will be three phases at each site observation A, intervention, observation B. Observation A: In this phase, the nurse identifies cases with severe AS at the hub AND the satellite and collects their data. Baseline data for each patient will be collected and a follow-up will be done after three months for each patient to determine his/her outcome and the treatment that was decided on. There will also be an optional telephone follow-up to find out the patient's outcome. Intervention: In this phase, the physician referring a patient for echocardiography will be notified of a finding of severe aortic stenosis: the nurse brings cases with severe AS to the attention of the referring physician within a week (via phone, e-mail or letter) to make them aware of the diagnosis. Baseline and follow-up data will be collected for each patient as before. Moreover, more detailed data with regard to the patient's health status will be documented. Observation B: Same as Observation Phase A
