Challenges in Implementing AI in NHS Healthcare: Insights from Recent UK Research

Implementing artificial intelligence (AI) technologies within NHS hospitals has proven to be more complex and time-consuming than initially anticipated, according to a comprehensive UK study led by researchers from University College London (UCL). The research highlights significant hurdles related to governance, contracting processes, data management, integration with outdated IT infrastructure, staff training, and the selection of appropriate AI tools.

The study, published in eClinicalMedicine, aims to provide valuable lessons for the UK Government’s strategic plan to digitally transform the NHS over the next decade, a key component of which involves integrating AI solutions to enhance patient care.

In 2023, NHS England initiated a program deploying AI technologies across 66 hospital trusts in England to improve diagnostics, particularly for chest conditions like lung cancer. These diagnostic networks enable more equitable access to specialist assessments, with AI tools supporting priorities such as quick identification of critical cases and highlighting abnormalities on scans.

The research team, comprising experts from UCL, the Nuffield Trust, and the University of Cambridge, analyzed the procurement processes and early deployment phases of these AI tools. Their efforts included interviews with hospital staff and AI vendors, as well as observations of governance, planning, and training protocols.

Findings reveal that setup times for AI systems extended significantly beyond original estimates, with contracting delays ranging from four to ten months. By June 2025, approximately 18 months after the contract deadline, about one-third of the trusts had yet to integrate the technology into clinical practice. Challenges cited include heavy workloads for clinical staff, difficulties in embedding new systems into legacy IT infrastructure, and variable levels of understanding and confidence in AI among staff.

Despite these obstacles, the study identified factors facilitating smoother integration such as national leadership, resource sharing through imaging networks, strong commitment from hospital staff, and dedicated project management. The authors emphasized the importance of training, education, and ongoing support to address skepticism and concerns regarding AI decision-making and accountability.

The study’s lead author, Dr. Angus Ramsay, emphasized that AI tools, while promising, are not a panacea for NHS service pressures, and their successful implementation requires careful planning, education, and resource allocation. Similarly, Professor Naomi Fulop highlighted the heterogeneity of hospital needs and IT systems, underscoring the complexity of deploying AI solutions across diverse settings.

The researchers are now extending their investigation to evaluate AI’s effectiveness after initial deployment, including patient and caregiver perspectives to better understand the impact on care quality and equity.

Overall, this research underscores that while AI offers significant potential in healthcare diagnostics, realizing these benefits requires addressing practical implementation challenges through strategic planning, staff engagement, and robust governance.
