Introduction

Introduction

Point-of–Care-Testing (POCT)

  • Providesanalternative

    tolaboratorytesting

  • Thatiseasy, portable,

    andaccurate

  • Allowsfortestingeither

Point of care testing in home and hospital

Point-of–Care-Testing

  • Cost-effective for many disease ,such as diabetes, acute coronary syndrome

  • Results can be shared instantaneously with all members of the medical team through software interface enhancing communication by decreasing turn around time

Advantages of poct

Advantages of POCT

  • Reduce TAT

  • Reduce errors

  • Reduce paper

  • Smaller sample size(microliters vs. milliliters)


Poct advantages

POCT: Advantages

  • Faster stabilisation of life-threatening crises (drug overdose, electrolyte disturbance)

  • Closer therapeutic management (eg. diabetes)

  • Better patient compliance with therapy (diabetes, anticoagulation, hyperlipidaemia)

  • Reduce:

    • repeat clinic/practice visits

    • length of stay in hospital

    • complications (intra- & postoperative)

    • use of blood products (surgery)


Poct advantages1

POCT: Advantages

  • Reduces the risk of preanalytical errors

    • the handling

    • the labeling

    • the transportation of samples

  • No need laboratorian staff. ???


Poct disadvantages

POCT: DISADVANTAGES

  • Analytical performance can be inferior to lab (eg. glucose meters), so need lab backup

  • Risk of poor operator competence

  • Risk of poor quality patient information

  • Risk of poor equipment maintenance


Poct disadvantages1

POCT: DISADVANTAGES

  • Cost per test (>>lab), so look at clinical & economic OUTCOMES of patient episode

  • All depend on the way equipment is selected and used

  • Lack of adequate documentation

    • results may get mishandled or misplaced

    • have an affect on potential reimbursement issues.

What were some of

the most important ‘tools’

that you used when you

first got involved

with POCT?


Poct informatic tools

POCT Informatic Tools

Early to mid 1990’s

  • Bench-top analyzers

  • Touch screen PCs

  • Results sent to centrallaboratory for analysis

University of Virginia Health Science Center – Original Home of RALS Technology


What s driving poc informatics

What’s Driving POC Informatics?

  • Hospital POC growth rate

  • Decentralized patient testing

  • Reducing overall healthcare costs


The information revolution

The Information Revolution…

As POCT evolves, needs will include:

  • Instant information

  • Getting more data to the EMR

  • Continuous glucose testing and monitoring

  • Open IT standards

  • RF and web-based communication and connectivity

  • Optimum security

  • It’s not just glucose anymore…

  • Goodbye Paper…Hello e-Patient


Goodbye paper hello e patient

Goodbye Paper…Hello e-Patient!

It’s a “Paperless” World!

  • EMRs reduce overhead andimprove efficiency

  • EMRs increase patient care


Goodbye paper hello e patient1

  • It’s not just glucose anymore…

  • Goodbye Paper… Hello e-Patient

  • Zero Tolerance for Errors!


Zero tolerance of medical errors

Zero Tolerance of Medical Errors

The Need for Data Management

  • Total control of POCT Programfrom device to operator topatient to test order

  • Federal initiative launched to reducemedical errors and improve patient safety


In the future

In the Future….

Look for more patient outcome data

  • Statistics to validate quality

  • New reports to allow users to sort data on various criteria such as nursing unit, patient, result, etc.

  • POCT as a separate laboratory department

Poct closer to home

POCT Closer to Home…

  • 2 million+ on Anti-Coagulation therapy

  • Warfarin - 22nd most common drug

  • 1,100 Clinics growing at 20% a year

  • Indications

    • Atrial fibrillation

    • Heart Valve replacement

    • Stroke


The use of portable coag devices

The Use of Portable Coag Devices…

Bedside testing enables:

  • Home health providers to make immediate changes in coagulation therapy if necessary

  • Frequent testing = Fewer complications

  • Home testing with data communication= improved patient management

Data management at home

Data Management at Home

  • Provides direct oversight by the care provider

  • Eliminates patient transcription errors

  • Allows for timely medication adjustment

  • Improves patient satisfaction


Point of care testing in home and hospital

1. Where are POCT diagnostics currently being used?

2. What are their benefits over lab based clinical

diagnostics?

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).


Point of care testing in home and hospital

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.


Point of care testing in home and hospital

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

foreseeable future.

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.
