430Q - Research Paper

Abstract
Aim:
The aim of our audit was to distinguish subclasses of HTN that were identified by the ABPM results.

Method:
Retrospective audit: inclusion of patients with CKD stages 4-5, home-dialysis, or transplant with OBP >140/90 and patients who had symptoms of low BP on multiple antihypertensives.  Data was collected from ABPM reports.

Results:
A total of 28 ABPM reports were reviewed.  Mean age of patients was 63.  Female 35.7%.  Patients with diabetes 21.4%, and Maori and Pacifica 21.4%.  White coat HTN 35.7%, uncontrolled day time BP 78.5%, uncontrolled night-time BP 85.7%, nocturnal dipper 35.8%, non-dipper 46.4%, reverse dippers 17.8%.  Interestingly there were 0% cases of masked HTN.

Conclusion:
ABPM is a useful tool to detect sub-classes of HTN, this helps to optimise HTN treatments.  Referral criteria is modified to identify patients with masked HTN.  Data showed patients with diabetes, Maori & Pacifica background were underrepresented.  We are considering rural HTN clinics to address the issue of inequity in service delivery.
