A convincing demonstration is only the beginning. The harder questions concern the problem being solved, the quality of the evidence and what happens when the product meets a busy clinical service.
Catena brings a clinician’s understanding of patient care together with technology and commercial judgement. The aim is to help you see where a product could be useful, what needs to be demonstrated and what it would take to adopt it responsibly.
Clarify the clinical problem, intended user and place in the care pathway. Examine product claims, shape an evidence plan and understand the workflow your product would need to fit. For teams that need continuing input, explore a fractional Chief Medical Officer or clinical advisory engagement.
Assess whether a tool addresses a meaningful service need and whether the evidence applies to your patients and setting. Define a pilot with useful measures, realistic staffing and clear responsibility for acting on the output.
Test the clinical case behind the commercial story. Examine the need, evidence, adoption barriers and unanswered questions that could change an investment decision.
From waiting lists and preoperative assessment to the operating theatre and recovery at home, technology is changing many different parts of the surgical journey.
The Catena landscape brings these tools together by the task they are intended to support. Each review explains what a product claims to do, how it works, what the available evidence tells us and the questions a buyer should ask next. The clinical reviews are being developed; their status and limitations are shown openly.
Stewart is a practising consultant anaesthesiologist, healthcare strategist and technology founder. His experience spans clinical care, NHS service improvement and Chief Medical Officer roles in health technology.
His MBA and experience building technology ventures inform the commercial side of the work: whether a product addresses a worthwhile need, can fit a viable service and gives people a reason to adopt it.
Catena brings those perspectives together in advice that is grounded in the working day of clinicians and the decisions facing a leadership team.
Sound advice also needs to be communicated clearly. Catena’s Knowledge Studio turns approved expertise and product material into onboarding, training and educational resources. It remains a supporting capability for organisations that need help explaining a complex product or changing how people work.
Whether you are developing a product, evaluating a tool or considering an investment, start with the decision and the questions you need answered.
We build academies that turn expertise into measurable outcomes.
SaaS teams cut time-to-value, lift activation, and reduce support load.
Professional Services firms standardise training and reduce operational risk.
Experts productise knowledge into credible courses that generate qualified leads.
