Netherlands Institute for Health Services Research Primary care of hypertensive patients and the risk of acute events Irina Stirbu-Wagner Markus MJ Nielen MaaikeLangelaan Robert A. Verheij Joke C. Korevaar
Why this study • Hypertension is one of the most important risk factors for developing acute events • Studies focused mostly on treatment options to reduce risk of acute events • Treated hypertension patients have various outcomes
Objective • To establish which factors play a role in determining the risk of an acute cardiovascular event in hypertensive patients. • We compared two groups of hypertensive patients: those who were hospitalised with an acute cardiovascular event (stroke or myocardial infarction) and those who did not experience any acute cardiovascular event and assessed the difference in: • use of GP care • medication [quality of care] • clinical parameters • demographic parameters
Methods Population Register GP database (EMR) About 400,000 people Dutch Hospital database (national) 80% probability linkage on DbGP 448 patients hospitalized with AMI/Stroke 34328 patients with Hypertension
Methods • Age • Gender • Comorbidities • Utilization of care • Medication • BP Event 448 hospitalized with AMI/Stroke 365 day follow up period 33880 patients no acute events
Results: health care use Mean number of contacts with GP
Results: health care use Event
Conclusions • The risk of an acute cardiovascular event (AMI stroke) in hypertensive patients • Demographic parameters: older men • Clinical parameters: more comorbidities, less controlled BP • Use of GP care: more contacts with GP long before event • Medication: more drugs prescribed • Possibility to link different registries on patient’s level
