Working to improve the future of healthcare

The CLH Research team is the Primary Care research hub for Central London. It manages and develops this service on behalf of the National Institute for Health Research (NIHR) for Federation member and non-member Practices.

The NIHR is the nation’s largest health and care research funder and provides the people, facilities and technology that enable research to thrive. It works in partnership with the NHS, universities, local government, other research funders (including industry and charities), patients and the public to improve the health and wealth of the nation.

If you are a patient registered within a Central London GP Practice, and are interested in participating in research, please see information below about our active research projects.

Live Projects



Cancer remains a leading cause of death globally, with early diagnosis crucial for effective treatment. CLOCS-2, a novel study, investigates the potential of everyday loyalty card data to identify early cancer signs. Focusing on various cancer types, CLOCS-2 compares purchasing patterns of participants to develop early detection methods. This innovative approach marks a promising stride in improving cancer outcomes.

BED & BN in primary care


Binge Eating Disorder (BED) involves frequent episodes of consuming significantly large quantities of food, accompanied by a loss of control over eating behavior. These episodes are marked by eating a substantial amount of food within a discrete period, surpassing typical consumption, and a feeling of inability to control eating habits.

Bulimia nervosa (BN) is a severe and potentially life-threatening eating disorder marked by episodes of binge eating followed by compensatory actions, like self-induced vomiting, aimed at counteracting the consequences of overeating and preventing weight gain.

Re-appraising the use of Faecal calprotectin sample (FC)


Faecal calprotectin (FC) serves as a recognized marker of inflammation, consistently displaying elevated levels in the stool of patients with inflammatory bowel disease (IBD) compared to control groups. Its utilization is endorsed by NICE for patients presenting with new-onset lower gastrointestinal symptoms.  Through this research endeavor will contribute to refining referral pathways, especially concerning cases with borderline elevated results.



Measuring Loneliness study (INTERACT2)


Social isolation and loneliness (SI&L) have well-documented public health implications, impacting both physical and mental well-being. To address the rising incidence of SI&L, particularly in the London Borough of Hammersmith & Fulham (LBHF &F), our research aims to assess its prevalence across England using online tools. We will focus on vulnerable populations, including those with limited cognitive capacity, developmental disorders, dementia, and serious mental illnesses, to identify interventions that can effectively tackle this issue. Our findings, disseminated through peer-reviewed journals, aim to inform policies and practices to address SI&L in communities across England.


Tricorder Study


Tricorder represents a collaborative effort between The NHS North West London Integrated Care System, Betsi Cadwaladr University Health Board, and Imperial College London, aimed at advancing public health outcomes. The project seeks to evaluate the impact of equipping GPs with the Eko DUO device on early detection of heart failure (HF) among patients, as well as its potential cost-saving benefits for the NHS.



FluCamp is a dedicated research organization with a primary focus on enhancing comprehension of viral illnesses, particularly respiratory infections such as the flu. Through meticulously conducted clinical trials involving volunteers under strict supervision, FluCamp aims to evaluate new treatments and propel medical research forward in this domain. By actively engaging volunteers, FluCamp endeavors to deepen our understanding of common viral infections and develop more effective treatments, ultimately striving to improve public health outcomes.


Active Brains


‘Active Brains  is a new website aimed at assisting older adults in maintaining brain and body health to prevent cognitive decline. Through promoting simple lifestyle changes such as increased activity, brain training games, and healthier eating, the platform aims to empower users. Ongoing research will assess the website’s effectiveness and cost-efficiency in delaying cognitive decline, providing valuable insights for improving support for older adults’ cognitive well-being.

Petra Study


Many people visit their General Practitioner (GP) with excessive, unpleasant worrying or feeling generally anxious, nervous, or tense. This can be called Generalised Anxiety Disorder (GAD) and often occurs alongside depression and low mood. GPs often prescribe antidepressants for worry and anxiety, but about half of people do not experience a reduction in symptoms.

Diamond Study


The Diamond study is a programme that is developed for people with type 2 diabetes to help them achieve remission. This means that a person has a normal blood glucose level and does not require any medication to manage their diabetes.

Being in remission will greatly improve a persons quality of life and will help them avoid the long term risks of diabetes.



Approximately 30% of people get Herpes Zoster or “shingles” and it is more common in people over the age of 50. It causes a painful, blistering rash, which lasts up to four weeks. The most common complication of shingles is post-herpetic neuralgia, which can be disabling for months-to-years.

The aim of the ATHENA study is to find out whether a medicine called amitriptyline stops adults with shingles getting “post-herpetic neuralgia” (nerve pain after shingles)

Indigo Community


If you have been treated for any type of cancer at any time before 2022 we want your opinions. Just because your cancer treatment may have stopped, has its impact on your life stopped?

Children’s Health Check


Are you a parent of a child aged 3 -13 years old, registered with a GP in central London?

Did you know you are eligible for a one-time children’s health check?

Starting in June 2023, Healthcare Central London and Central London Healthcare are running the first-of-its-kind child health clinic Within the session, an advanced nurse practitioner will complete physical checks and reviews. This will be a unique opportunity to discuss any concerns regarding your child’s health and to get support with their future wellbeing.

All attending children are eligible to do a screening test for type 1 diabetes. This is completed by a simple finger stick blood test but it is completely your choice if you would like us to do this in the session. Please note, children with no family history of diabetes are still at risk of developing diabetes. This simple screening can indicate whether or not your child is at risk in the future.
