At The Heart Of Healthcare Technology For 48 Years!

As we celebrate our 48th year in business I’ve recently taken a nostalgic look back over the various innovative products PMS have introduced to the UK healthcare market since 1975.

Some of them really were ahead of their time and have led to the development of subsequent products still in use today. Here I take a look back at a few of the more notable ones.

1994 – A&D Medical TM-2421 24 Hour Blood Pressure Monitoring System

The UK’s first dual method, Korotkoff Sound/Oscillometric 24 hour BP monitor, it proved to be very popular from 1994 to 2007 when it was replaced by the improved A&D TM-2430 24 Hour BP monitor.

1995 – E – Z Therm The 3 Second Thermometer

This was one of the UK’s first Tympanic thermometers. It was very popular and sold in large numbers. The fast measurement time meant it was popular for use in children and as a replacement for Mercury thermometers.

1997- A&D Medical UA 767 Digital Blood Pressure Monitor

The classic low cost and easy to use three in one digital BP monitor that gave systolic, diastolic and heart rate simultaneously on a large LCD display. Clinically validated it was popular with GPs and Hospitals as well as being used for clinical research. The latest generation is the A&D Medical UA-767 + AFib still one of our most popular digital BP monitors used extensively by the NHS.

2003 – Meditech Merlin ECG watch

Ahead of its time and before Smartwatches were available the Merlin watch was a low-cost ECG event recorder designed to capture transient arrhythmias. It was easy to wear and activate and could store up to 15 minutes of ECG recordings. PMS sold the watch until 2013 when it was discontinued by Meditech. It led to the development of the Meditech CardiUP3! Holter ECG. The latest AliveCor KardiaMobile 1L and 6L are great examples of how mobile ECG technology has moved on.

2009 – Tidi Disposable Cuff Barriers

Originally introduced by PMS as a cost-effective alternative to expensive single use blood pressure cuffs and as a hygienic solution to using fabric cuffs. They are still by the NHS today and were especially popular during the COVID-19 pandemic.

Introducing these products helped establish the PMS Instruments ethos of being At The Heart Of Healthcare Technology and to the development our innovative product range which still includes 24 hour blood pressure monitors, waiting room and digital blood pressure monitors, and mobile, resting and Holter ECG monitors.

Does It Matter What Time You Take Your BP Medication?

The Treatment in Morning versus Evening (TIME) study has recently been published. The study compared the morning dosing of blood pressure lowering medication with evening dosing of the same medication for people with high blood pressure.

Previously it was thought that the time of day you took your medication influenced how effective it was.

However, the results of the TIME Study by the University of Dundee has shown that the time of day you take your medication does not have any impact in terms of heart attacks, strokes or cardiovascular death.

The study included 21,104 patients over the age of 18 with high blood pressure from across the UK (England, Wales, Scotland and Northern Ireland). Each participant was randomly instructed when to take their medication.

There were slight differences in side effects. Patients who took their medication in the morning were more likely to report feelings of dizziness, light-headedness, indigestion, upset stomach, diarrhoea and muscle aches. Those who took their medication in the evening were more likely to report an increase of visits to the toilet.

These results mean that a patient, with their doctor can choose which time of day to take their medication to minimise side effects and which time of day suits them the best.

The TIME study was sponsored by the University of Dundee and funded by the British Heart Foundation (CS/14/1/30659). In addition, the study was supported by the British and Irish Hypertension Society, SHARE, UK Biobank, and UK Clinical Research Networks (UKCRN).

Review of the Meditech ABPM-06

It’s not that often that Meditech introduce a new ABPM. The last one, the ABPM-05 was introduced in 2007 the year the iPhone was launched. When they do it’s worth the wait.

There is a lot of thought that goes into the design and features customers really want in a new monitor. As well as good design it is important the technical elements are addressed so that the 30 year plus reputation for reliability and accuracy that Meditech have and customers from around the world expect, is maintained.

We’re proud that Meditech chose PMS Instruments and the UK as their first launch partner for the new ABPM-06 so what’s it really like to wear, use and operate?

First impressions are good. It’s got the same familiar look as the ABPM-05 which means it’s compact and light.

It uses the same size and type of wipeable cuffs which means users of the old ABPM-04 and ABPM-05 can use their existing cuffs interchanging between units. The cuffs are durable and easy to wipe clean which is important for patient hygiene.

One major improvement is the type of PC interface cable the new ABPM-06 is supplied with. The old ABPM-04 and ABPM-05 used either a serial interface or USB optoelectronic fibre optic cable which was unique to Meditech. Although repairable these old cables are expensive to replace or purchase new.

As customers frequently want to use their ABPM in more than one treatment room the new ABPM-06 is now supplied with a standard mini USB A mini to USB B PC cable. This resolves any potential cable comms issues as there is only one way the cable will go in.

Meditech have taken the wise decision to integrate the ABPM-06 into their popular CardioVisions analysis software rather than offer a completely new software platform. This means the look and feel of the software, programming, downloading and printing will be familiar to users of the old ABPM-04 and ABPM-05 with no new software to learn.

Programming the ABPM-06 takes seconds and key patient information like name, date of birth and ID is retained in the monitor so there is no doubt who has worn the monitor.

In the interests of customers I have worn a new ABPM-06 twice now and found the monitor comfortable and unobtrusive throughout.

I programmed the monitor to record every 30 minutes during the day and hourly during the night as recommended by the latest NICE guideline NG136.

Of the 40 readings taken over 24 hours all were successful with no errors. I was aware of the monitor going off at night but the new SleepWell® function added to the new AA grade algorithm meant the device wasn’t uncomfortable and the measurement inflation and deflation time was quick.

Downloading the results took seconds and the automatic text reporting, trend graph and presentation of key metrics like average daytime reading value are clear.

Feedback from new and existing customers who have purchased the ABPM-06 since we introduced it has been very positive. For a free demonstration, loan or for more information just call or email us.

The twenty year wait has been worth it!

The new A&D Medical TM-2440 and TM-2441 Ambulatory Blood Pressure Monitors are now available to pre-order from lead distributor PMS Instruments. They replace the old TM-2430 which PMS originally introduced in 1998.

Engineered in Japan, they are the 4th generation of A&D ABPM monitor PMS Instruments have launched in the UK and easily the most advanced to date. Both new models have a number of new innovative premium features.

With the launch of 2 new ABPM monitors at once the twenty year wait has been worth it!

The A&D TM-2440 Classic abpm comes as standard with fast measurement time, silent operation and with a world first in an A&D ABPM, IHB (Irregular Heart Beat) analysis technology.

This ground breaking technology pioneered by A&D in 2001 is now used worldwide assisting in the opportunistic detection of arrhythmias – which include AFib (or Atrial Fibrillation). It features Oscillometric waveform measurement analysis and with the new analysis software you can check the waveform record for each measurement.

The TM-2441 Premium ABPM with it’s all in one design concept offers the clinician and patient complete flexibility, providing Ambulatory (ABPM), Home (HBPM), Office (OBP), Automatic Night Blood Pressure (ANBP), and Automatic Self Blood Pressure (ASBP) measurement/monitoring in one device.

In addition to the Irregular Heart Beat analysis technology, it records environmental factors including Activity using a built in Accelerometer, Temperature and Air Pressure. The new TM-2441 provides additional more insightful view of the patient beyond just blood pressure recording and heart rate information – helping build a better picture for clinical decision making.

Both models for the first time are available with 4 different cuff sizes small, adult, large adult and extra-large adult with sizes fitting an arm circumference from 15-22cm right up to 36-50cm.

The new AND Analysis software allows PDF reports to be exported to popular clinical management systems like EMIS and SystmOne and is compatible with the old TM-2430.

The TM-2440/TM-2441 feature both USB and Bluetooth communication, use just 2 AA batteries and at just 120g, the TM-2440 is one of the smallest, lightest ABPM monitors on the market.

Is 24 Hour ABPM Still An Indispensable Tool In The Management Of Hypertension?

Ambulatory Blood Pressure Measurement (ABPM) has been used increasingly in clinical practice over the last 30 years. With the rise and adoption of low cost home blood pressure monitoring is it still an indispensable tool in the management of hypertensives in General Practice?

I first asked this question in an article I wrote for Practice Management magazine in 2010. I concluded that it was but in the intervening years is this still the case?

In the light of clinical developments and the publication of guidelines like NICE Guideline CG127 on Hypertension in 2011 and latest update in November 2016 is it still relevant?

Some background

In recognition of the importance of ABPM, the British Hypertension Society (now the British and Irish Hypertension Society), the European Society of Hypertension and NICE CG127 have all published guidelines for the use and interpretation of ABPM in clinical practice.

Traditionally, hypertensive patients had been assessed using clinic based blood pressure readings by a Nurse or Doctor. This changed in 2011 and recognition was formally given to the importance of using 24 hour ABPM monitoring.

The old “snapshot” approach to blood pressure measurement could give inconsistencies and over-estimate a patient’s blood pressure by anything up to 30mmHg.

The so called White Coat Hypertension, leading to elevated blood pressure is well documented and can lead to unnecessary prescription of hypertensive medicines. This has a profound clinical and financial relevance to Primary Care and can lead to inappropriate diagnosis and treatment. Ambulatory Blood Pressure Monitors provide much more consistent readings over a 24-hour period and give multiple measurements throughout the day and night.

CardioVisions NICE Software keeps it simple.

Modern ABPM software can produce a plethora of statistics and data which even for experienced clinicians can be overwhelming.

As a response to this and in view of the 2011 NICE guidelines we introduced our CardioVisions NICE software. This provided a meaningful textual analysis ensuring clinicians got reporting continuity to a recognised clinical standard as well as importantly saving Doctor and Nurse time. It’s compatible with the Meditech ABPMs and a typical report may read something like this.

“The ABPM was worn by the patient for 24 hours. During this period the average daytime blood pressure was 169/118 and the pulse rate was 88 beats per minute. According to NICE guidelines the patient exhibits stage 2 hypertension. The examination was divided into day 06:00-22:00, night 22:00-06:00. 64 successful readings were taken during the daytime period and the NICE key quality requirement for 14 has been met. During the daytime there were 64 readings (100.0%) above the NICE guideline figure of 135/85. The highest reading was 202/134 recorded at 9:15 22/05/1997. During the night time period 24 successful readings were taken and the average blood pressure was 135/87.”

The detailed stats, graphs and readings are still there for those that want them but the textual analysis summary can be copied and pasted into the patient notes and also attached to popular clinical management systems like EMIS Web and SystmOne. There is no annual licence fee and multiple copies can be installed.

What about home blood pressure monitoring?

The cost of clinically validated home blood pressure monitors has fallen since 2010 and a number of GP Practices have been loaning monitors like the UA-767S-W to patients. Home monitoring is great for the small number of patients that find ambulatory blood pressure monitoring inconvenient or difficult tolerate but it’s not ideal for everyone and can be difficult to manage in practice.

For home blood pressure monitoring NICE recommend patients should measure their blood pressure twice a day, ideally once in the morning and once in the evening, while sitting down. Each time they do this, they should take two readings, 1 minute apart. They should continue to measure their blood pressure twice daily for at least 4 days and ideally for 7 days. Some patients may find this onerous and patient compliance can vary. A 24 hour monitor is only worn for 24 hours!

All the measurements taken after the first day are used to work out average day time blood pressure but again this can be time consuming and may be subject to error.

Whilst home blood pressure monitoring gives multiple readings, it relies on proper patient technique, patient training and compliance for up to seven days to give meaningful results.

As a complementary technique to 24 hour ABPM it can be useful to monitor patients with long term chronic conditions such as diabetes and coronary heart disease.

On the flip side the detail, automatic analysis and reporting, 24 hour ABPM provides with very little user or patient input just isn’t available with home blood pressure monitoring.

Night time readings cannot be recorded and for many 24 hour ABPM remains the “Gold Standard”.

So why doesn’t everyone use 24 hour ABPM?

For some the initial cost is off putting but the cost of 24 hour ABPM monitors has fallen since 2010.

The latest 24 hour BP monitors like the Meditech ABPM-04 and ABPM-05 are reliable with low running costs, long warranties and a low overall cost of ownership.

PMS Instruments now offer a flexible rental ABPM service which means cost can be spread over several months and for a low monthly fee service and calibration is covered.

“Is 24 Hour ABPM Still An Indispensable Tool In Management Of Hypertension?” my answer would still be yes.

The missing 5.5 million with undiagnosed high BP.

A new resource – Blood Pressure – How Can We Do Better? – has just been launched and can be accessed at the British Heart Foundation website.

It has been developed by stakeholders including GPs, nurses and pharmacists working with organizations including NHS England, Public Health England, the British Heart Foundation, the Stroke Association and the Royal College of General Practitioners.

It is well known that high blood pressure affects one in four adults in England and is one of the leading causes of premature death in England. At least half of all heart attacks and strokes are associated with high blood pressure.

Treatment thankfully is very effective – for every 10mmHg reduction in blood pressure, the risk of a life changing heart attack or stroke is reduced by 20%.

What’s the challenge?

Finding undiagnosed hypertensives, around 25000 in the average CCG or 5.5 million in England, unaware of their increased risk and not receiving treatment is the challenge. It’s also worth remembering that of those diagnosed with high BP, one in three, are not treated to target.

GP Practices and Clinical Commissioning Groups (CCGS) need to do things differently to improve detection and increase opportunistic screening.

What practical steps should GP Practices take?

Think BP! Whether in routine consultations, or in nurse led clinics, like COPD, asthma and diabetes. Encourage opportunistic screening and ensure identification of poor BP control is the responsibility of all clinicians.

Think BP! In accordance with NICE CG127 guideline on Hypertension always offer ambulatory 24 hour blood pressure monitoring or when appropriate home blood pressure monitoring to confirm a diagnosis of high BP. Ensure BP equipment is serviced and calibrated regularly by reputable third parties with experience of the devices you use.

Think BP! Use clinically validated waiting room self-test BP monitors like the A&D Medical TM-2657P to make it easier to collect BP data, save appointment time and empower patients to actively use this equipment.

Think BP! Advise patients of the option to buy clinically validated low cost blood pressure monitors like the UA-767S from established suppliers so they can monitor their blood pressure at home.

There is also a role for Clinical Commissioning Groups (CCGs) who need to do things differently to improve detection, support GP Practices and increase opportunistic screening.

They can use the BHF website to see how many people in their CCG have undiagnosed high blood pressure.

How do we diagnose more patients with high blood pressure?

Time pressured consultations and other clinical priorities are a factor and simply mean in many instances there isn’t enough time to record a blood pressure. The answer is the wider adoption of technology like the A&D Medical TM-2657P waiting room BP monitor and doing things differently.

How does it work?

Patient self-measurement of blood pressure using A&D waiting room blood pressure monitors have been used in the UK since PMS Instruments introduced them in 2002. They are an established part of many GP Practices hypertension diagnosis and management pathways. Put simply the patient records their blood pressure which is printed on a paper slip. This is then shown to the clinician during the consultation. The readings can be input to the patient’s clinical record.

What does the future for detection and management of high BP hold?

With no extra capacity at present the situation won’t be improved by GP’s working harder. It may be improved by doing things differently, changing the system and the wider adoption of new technology. If you are a GP Practice, CCG or GP Federation and want to find out more about the latest BP measuring technology contact me.

24/7 ABPM Guidelines Revisited

NICE clinical guideline 127 states that ABPM monitoring is the most accurate method for confirming a diagnosis of hypertension, and its use should reduce unnecessary treatment in people who do not have true hypertension. Originally published in 2013 it was updated in September 2015.

In a recent review with our technical support team I asked them what were the practical questions they were most frequently asked about the guideline and ABPM in general.

I thought I would share the results on our Blog as they may be of interest to other ABPM customers. In no particular order this is what they told me.
