Update: 16.3.2020

The Council on Hypertension of the European Society of Cardiology wish to highlight the lack of any evidence supporting harmful effect of ACE-I(Ramipril, Lisinopril, Perindopril & Enalapril) and ARB (Candesartan, Irbesartan, Losartan). in the context of the pandemic COVID - 19 outbreak.  The council of Hypertension strongly recommend that physicians and patients should continue treatment with their usual anti-hypertensive therapy because there is no clinical or scientific evidence to suggest that treatment with ACEi or ARBs should be discontinued because of the COVID-19 infection

Greenfield Medical CentreHas a practice population of 6900 patients.  There has been a practice on the site since the 1950's.  Originally 1 house at number 143 the practice expanded to include number 145 and over the years a process of modernisation was undertaken to completely link the 2 buildings.  The practice has 8 consulting rooms and 2 treatment rooms.  The building has a modern reception and administrative area.  The practice has car parking with disabled bays, disabled access and disabled toilet facilities.  

Situated within the London Borough of Barnet the practice sits at the most southerly end of the borough, bordering the neighbouring boroughs of Brent & Camden and on the main commuter routes into Central London.

The practice serves a mixture of patients from both affluent and deprived areas.  Over the years the cultural change has seen shift from a high proportion of Irish & Asian patients to a more Eastern European and Middle East Patients moving into the area.  Age ranges have also changed with the majority of our patients being under 65.

There are currently 2 clinical partners Dr Antonia Briffa and Dr Hilary Dunseath and 1 non clinical partner/Practice Manager  Jacqui Tonge.  The practice has 3 associate GP's 1 Nurse Practitioner and a Practice Nurse.  There are a team of 7 reception/admin staff who support all non-clinical aspects of the practice under the management of the non clinical partner/practice manager.

The practice is a "training practice" and currently hosts an ST3 registrar and 2 FY2 doctors.  During the autumn/winter 1st & 2nd year medical students also attend for 1/2 day a week.

The practice is also very involved in the Barnet GP Federation, with both Dr Briffa and Jacqui Tonge being part of the original board until stepping down in 2017.  They both retain an interest in the federation with training and governance roles.  The practice is a HUB for the federation's enhanced appointment scheme hosting a minimum of 3 times a week from 6.30 -9pm and 8-12 on a saturday morning at the surgery and across Barnet 7 days a week. The practice  is now part of The Primary Care Network working closely with 7 other practices.

Using Emis web as our clinical system the majority of our daily work is now paperless.  We refer via the Barnet Management Referral Service, and monitor our referrals internally for quality assurrance.

We encourage personal & professional development and believe that our staff are our greatest assett.

Practice meetings are open and transparent and we use this time to reflect on how we are doing.

We have an active patient participation group who have supported us with policy changes.

Out of hours care is provided by "Barndoc" via 111
