In community psychiatry, Clozapine clinics often serve as the backbone of care for patients with treatment-resistant schizophrenia. Yet, while these clinics provide specialist oversight and structured monitoring, the requirement for frequent full blood count (FBC) testing remains a persistent operational and clinical challenge. Regular venous blood draws can be distressing for patients, time-consuming for staff, and logistically demanding within already stretched NHS community services.
This whitepaper explores how Kent & Medway Mental Health Trust introduced the point-of-care CBC analyzer HemoScreen at its Maidstone Clozapine Clinic in early 2025. This compact system delivers laboratory-accurate FBC results from a simple finger-prick sample in minutes, addressing a critical barrier in Clozapine monitoring and reshaping what is possible in fast-paced community mental health settings.
The National Health Service (NHS) delivers mental health care primarily through regional NHS Foundation Trusts that integrate hospital, community, and social care services. Within this structure, community mental health teams (CMHTs) play a central role in delivering long-term psychiatric treatment, managing medication adherence, and ensuring continuity of care close to patients’ homes.
Clozapine clinics are typically operated within these CMHTs, serving as specialized outpatient facilities that conduct psychiatric reviews, blood sampling, and medication dispensing. However, many of these clinics face severe staff shortages and high patient volumes. The balance between clinical oversight and the operational challenge of managing frequent, time-sensitive blood testing remains a daily pressure on already stretched resources (NHS England).
The Kent & Medway Mental Health Trust (KMMH) provides mental health and social care services for over 1.9 million residents across Kent and Medway in South East England. The Trust operates more than 60 sites, including inpatient wards, community teams, and outpatient centers. Its network includes specialist Clozapine clinics in Maidstone, Canterbury, Dartford, and other locations.
The Trust’s community teams have earned recognition for their person-centered approach and commitment to improving accessibility to treatment. Within this context, the Maidstone Clozapine Clinic at Albion Place undertook a service evaluation in early 2025 to examine whether the introduction of the PixCell Medical HemoScreen point-of-care analyzer could enhance patient satisfaction, streamline clinic operations, and improve adherence to Clozapine monitoring protocols (Kent & Medway Mental Health Trust).
The service evaluation, conducted between February and March 2025, compared patient experiences using the new HemoScreen system with those of the previously used Sysmex pocH-100i device. HemoScreen, a compact, laboratory-accurate analyzer, performs a full 5-part differential FBC using a single drop of capillary blood collected via finger prick.
The test provides results in approximately five minutes through a self-contained cartridge system that requires no maintenance or calibration.
The evaluation concluded that introducing HemoScreen was “a game-changer” for Clozapine monitoring, particularly for patients with needle phobia or difficulty providing venous samples. Based on the overwhelmingly positive results, KMPT decided to expand HemoScreen deployment across all Clozapine clinics and inpatient units.
“We are extremely pleased with the results we’ve seen from HemoScreen. The addition of the finger stick option, alongside the ability to use venous samples, has been a significant benefit for our patients.
The finger stick option, in particular, has been a game-changer for patients with needle phobias, allowing us to offer Clozapine treatment to those who may have previously been reluctant due to any reasons.
The flexibility of HemoScreen in accommodating both types of samples has greatly enhanced patient adherence to treatment. By reducing the barriers associated with traditional blood draws, we have been able to support more patients in staying on track with their treatment plans, ultimately improving their care and outcomes.
Based on the roaring success of the trial, we are excited to be expanding the use of HemoScreen to additional locations across our trust.”

The successful deployment in Maidstone underscores a broader lesson for community mental health services across the UK. CBC testing, which is an essential but often underestimated component of psychiatric pharmacotherapy, can impose significant operational strain on clinics and emotional strain on patients.
By offering accurate, laboratory-grade results from a finger-prick sample within minutes, HemoScreen alleviates these barriers. It provides clinical teams with immediate, reliable data to continue Clozapine safely, while giving patients a less invasive, more dignified experience. The ease of operation and minimal training requirements make it ideally suited for multidisciplinary teams working outside major hospital laboratories.
In community psychiatry, where staff work tirelessly to deliver complex care within constrained budgets and time, technologies like HemoScreen offer more than convenience—they extend the reach and resilience of the NHS, supporting clinicians and patients alike.
