What were some of
the most important ‘tools’
that you used when you
first got involved
Early to mid 1990’s

As POCT evolves, needs will include:
Emerging Trends inPoint-of-Care and theirImpact on Data Management…

requirements for quality and competence
Non Hospital POCT – Primary care
Point-of-care testing` (POCT) -- Requirements for quality and competence
UKAS Individual Licence
1. Where are POCT diagnostics currently being used?
2. What are their benefits over lab based clinical
Depends on clinical context, circumstances & quality of
local POCT management
3. What are their current limitations?
Cost, IT networking capability, ?wireless, ease of use,
insufficiently “idiot-proof” and robust, range of tests
available. Need more non-invasive systems (eg bilirubin)
Little currently on the market for continuous minimally
invasive monitoring (eg for diabetes).
4.What features could be improved?
Simplicity of use, miniaturisation, robustness (device &
consumables), costs, IT connectivity, remote lockout for
unaccredited users, decision support software, inclusion of
quality materials within costs, training support. Suppliers to
encourage “whole system” approach to implementation as
part of local diagnostic support.
5. Do they provide clinically useful information? Are they what clinicians want?
Very dependent on appropriate implementation and
consideration of outcomes. Clinicians want ease of use,
reliability, low cost. Managers want improved capacity &
throughput, reduction of beds and staff costs.
6. Do the current POCT diagnostics provide the
required sensitivity and accuracy?
Requirements differ depending on circumstances; quality of
results dependent also on competent use
7. Will POCT diagnostics replace lab based
diagnostics or will it be the other way round?
NEITHER: both are an essential & integral part of
diagnostic provision and will continue to be in the
Major changes in profiles of healthcare provision, IT
developments, analytical technology, requirements of
Clinical Governance and risk management --> blending of
deliveries and need for increasing flexibility of systems.
