Our Clinical Team – a guide to new roles within our team

At Elm House Surgery, there has always been an ethos of learning and development for our staff. We have continued to achieve this over the years by welcoming GP trainees into the practice for their vocational training as well as employing staff across the Primary Care spectrum called Allied Health Professionals.

As part of the NHS Long-Term Plan, there has been a drive to increase the number of Allied Health Professionals within Primary Care. This is due to the ever-increasing demands on GPs and the need to ensure the right workforce, with the right skills, is in the right place to deliver high-quality care. As a patient, you may get seen by any one of these Allied Health Professionals when you have an appointment. We understand that some of the titles may be confusing.

So we have outlined the different Allied health professionals we employ at Elm House Surgery and their roles within the practice:

Our Clinical Pharmacists play a crucial role in medication management. They work closely with our doctors to optimise drug therapy, prevent medication-related issues, and educate patients about their medications. This collaboration ensures safe and effective treatment plans.

Advanced Nurse Practitioners (ANPs) are experienced nurses with specialised training, allowing them to diagnose and treat a variety of health conditions. They provide high-quality primary care, perform physical exams, order and interpret diagnostic tests, and prescribe medications, all while emphasising a holistic and patient[1]focused approach.

Physician Associates (PAs) are highly skilled healthcare professionals who work independently, and can diagnose, investigate and provide treatment plans for patients. They can approach our GPs for advice if required. Prescribing is not within their scope of practice. As such, any prescriptions will be signed off by a Clinical Pharmacist or a GP. PAs are integral members of our team, ensuring timely and efficient patient care.

First Contact Physiotherapists (FCPs) are qualified autonomous clinical practitioners who can assess, diagnose, investigate, treat and discharge a patient with any musculoskeletal complaint without a medical referral – where appropriate. They can also refer onwards for further intervention to the specialised Musculoskeletal Clinical Assessment and Treatment Service (MCATS) or to the Orthopaedic Team.

Mental Health Practitioners (MHPs) are experienced professionals who can support patients with either a diagnosed or undiagnosed mental health concern. This could be one or a number of mental health symptoms such as anxiety, low mood, loneliness, grief, hallucinations or stress.

As a training practice, our GP Trainees work as part of the clinical team. A GP Trainee is a qualified doctor who already has hospital experience and who is now undertaking specialty training for General Practice. Whilst they are with us, they are always working under the supervision of a fully trained GP. They will usually see you by themselves but will seek further advice from the supervising GP where needed.
