About Us
Our Vision

We help healthcare providers improve outcomes for patients by designing care that is safe, effective, efficient and person-centred. Using human factors, we strengthen decision-making, service design and organisational culture so you can achieve measurable reductions in harm and reliable improvements in performance.
Why Human Factors?
Healthcare is complex: patients’ needs vary, teams work under pressure, and care is delivered across very different settings. Human factors helps you understand how work is really done, design systems that support staff performance, and learn effectively from both success and harm. We build your capacity for complexity so care can be tailored to individuals while remaining practical and deliverable for teams.

Why Promethean HD?
We specialise in applying human factors in healthcare to help providers deliver safe, effective, affordable, person-centred care, and demonstrate to regulators that services are safe and well-led. We support you to:
-
Design and implement services, pathways, processes and work systems that work for patients and staff.
-
Investigate and learn from incidents, complaints and success, strengthening learning without blame.
-
Strengthen governance and assurance so decision-making is clear, evidence-based and insight-driven.
-
Build capability through coaching, mentoring and practical tools that teams can use day to day.
Every project is led by Chartered Ergonomist/Human Factors experts and delivered to consistently high professional standards. We have 20+ years’ investigation experience, including 13+ years focused on healthcare safety investigations. We help clinicians and leaders apply proven approaches from safety-critical industries to build high-performing, reliable organisations.
We also bring senior and executive governance experience from both NHS and independent healthcare. This means we can connect board assurance to the realities of frontline work, helping Boards apply the same design discipline to information, assurance and decision-making that safety-critical industries rely on.
