Telemedicine in Singapore: from Humble Beginnings to an Essential Service

Telemedicine in Singapore: from Humble Beginnings to an Essential Service

Telemedicine in Singapore: from Humble Beginnings to an Essential Service

Humble Beginnings 

Telemedicine was created from the growing concerns about access to healthcare, together with advanced telecommunication and information technologies. With Telemedicine, there were no “physical barriers” and patients could consult doctors from far distances. 

Telemedicine allows for long-distance patient and clinical contact, monitoring, care and advice.

This greatly reduced the need for physical doctor visits and medication refills. Instead, we can now see doctors online from the comforts of home!

However, in its introductory stages, Telemedicine was not widely received. Being a new invention that is vastly different from its traditional counterpart, many doubted its effectiveness and accuracy.

In countries dominated by an ageing population, such as Singapore, where the majority of patients are not tech-savvy, there was a low need and demand for online healthcare. Rather, most found traditional doctor visits easier. 

Challenges Faced

Digital healthcare faced the challenge of breaking the misconception towards Tele-Consultation and online healthcare with worries on misdiagnosis without physical checks, lack of qualified doctors online and possible service disparities.

Coupled with the lack of funding support from local governments and few clinics willing to partner with Telemedicine corporations —

It was hard for Telemedicine to establish a significant foothold in the healthcare industry.

The Global Pandemic & A Hidden “Blessing”

However, with the emergence of Covid-19, it has since removed barriers to digital health.

Regular physical doctor visits became risky or impossible, and healthcare services were limited. Advised to stay home, many who needed doctor consultations or medication refills turned to online alternatives.


This marked the turning point for Telemedicine as more people began switching to Telemedicine for their health checks.

On average online visits have increased by more than 160% since the start of 2020 for many Telemedicine providers.

The ability to receive medical care from a safe distance, without risking infection, proved to be the most attractive factor that accelerated the acceptance of Telemedicine.

Online healthcare thus proved to be a hidden “blessing” for many from home. 

The Endless Possibilities with Telemedicine

Telemedicine serves beyond mere online consultations with doctors. The introduction of Tele-Consultation and Tele-Monitoring is starting to be used for remote patient monitoring and follow-up.

Tele-Monitoring allows for regular follow-ups with patients, especially those with chronic conditions, by regularly monitoring their health vitals daily. It allows both the doctor and the patient to take an active role in their care, while reducing their visits to hospitals. 

The growing global pandemic has caused healthcare systems worldwide to report strains in healthcare facilities and manpower. Telemedicine represents an important tool in helping reduce this burden.

Its role in the optimisation of healthcare resources, reduction in the number of visits to clinics and hospitals, and ability to deliver necessary medications to homes evidently shows its importance to the sustainability of healthcare systems.


Benefits of Telemedicine

There are many benefits of Telemedicine, establishing its position as a strong alternative to traditional healthcare such as:

1.  Safety from Home

With the emergence of Covid-19, many avoided visiting hospitals and clinics in fear of exposing themselves to risk of infection.

Regular doctor check-ups were missed and patients with chronic conditions were unable to get their medication refilled. 

However, with Telemedicine, patients can consult their doctors for non-serious illnesses from the safety of their home. They can stay well-protected, receive doctor’s advice and have medication delivered without having to leave the house.

2. Avoid the Queues

Experiencing cough, fever, headaches?

But lack the time and energy to travel to the nearest clinic and waiting in line?

Avoid the queues with Telemedicine and easily fix a consultation with your doctor with just a few taps without having to wait in line for your turn.

3. Seamless Convenience

Telemedicine is not bound by physical barriers.

Fix a consultation with your preferred doctor that can best fit into your busy schedule. 

No longer worry about time constraints as Telemedicine allows for your doctor “visits” to be seamlessly incorporated into your daily lives. Furthermore, if you feel unwell during the day, easily schedule a consultation and receive your doctor’s advice and medication by the end of the day!

4. Lifetime Coaching & Support

Daily self-monitoring is made possible with Telehealth platforms, like HeartVoice. Especially for long-term chronic patients who require extra care, self-monitoring from home allows your doctor to regularly check your health vitals and provide better advice and support catered to your health needs.

5. Personalised Treatment & Quality

Similarly, with home monitoring, your doctor can better tailor treatments for your health problems. Daily monitoring is crucial for doctors to check how well your body is responding to the treatment and if changes need to be made. In doing so, your doctor can personalise your treatment to be more effective and efficient.

Telemedicine improves quality of care delivery as doctors can better target your health problems with specific treatments and solutions.

Furthermore, with better information on your own body, lifestyle adjustments can be easier changed.

Your lifestyle habits can affect how your body feels — be it an exercise regime, diet or sleep habits. With regular monitoring of blood pressure, weight, body fat and skeletal muscle, you will be able to see the impact of your lifestyle changes and make data-based decisions.

6.  Remote Patient Monitoring

Tele-Monitoring also serves as monitoring for clinical signs of chronic diseases.

Early detection and early treatment is crucial in minimising the health impact of the disease. 

Active self-monitoring also serves to raise awareness within patients — leading to them taking more responsibility for their health by changing their lifestyle habits and diet. This reduces the chances of falling sick and having to see a doctor.

7. Access to Specialist Opinions

Telemedicine allows for the leverage of specialist opinions, on top of your doctor’s advice.

When it comes to serious health issues, it is best to gather the most information before making a decision. Even if these specialists are not near you, Telemedicine has created a platform to easily seek their advice without wasting extra time and money for transport. This allows you to make the best decision for your health.

A New Age

Telemedicine is undoubtedly the new age of healthcare worldwide.

The benefits that it brings are endless.

It is shifting the way doctors are treating their patients and how patients receive healthcare. As the world battles against Covid-19, Telemedicine is the key to sustaining healthcare systems. One thing is for sure:

Telemedicine is already on its way to becoming an essential service.

Hypertension and Why Monitoring Blood Pressure is Important

Hypertension and Why Monitoring Blood Pressure is Important

Hypertension and Why Monitoring Blood Pressure is Important

Hypertension is the most common preventable cause of cardiovascular disease. As high as 25% of Singaporeans aged 40 – 69 suffer from hypertension. That is a whopping 1 in 4 ratios! Health Promotion Board data from 2015 shows that 74% of patients who have had heart attacks had hypertension as a risk factor. 

Your heart is the most important organ in your body; and we should always love and care for it.

What exactly is hypertension?

Hypertension is the state of elevated blood pressure. 

Having attained the name “silent killer, hypertension shows almost no symptoms until it has done significant damage. 

You won’t even know you have it until it’s too late.

Watch out for these risk factors!

Modifiable risk factors include unhealthy diets (a diet high in saturated and trans-fat, high intake of processed food, colored drinks and sweetened foods, low intake of fruits and vegetables), lack of regular physical activity, and consumption of tobacco and alcohol.

Non-modifiable risk factors include old age (averagely above the age of 65) and a family history of hypertension.


Why should I be worried?

Many of us must be thinking, why should I be worried?

Long-term complications of uncontrolled and high hypertension are:

1. Heart attack, which occurs when the blood supply to the heart is blocked and heart muscles die from the lack of oxygen. 

2. Heart failure, which occurs when the heart is unable to pump sufficient blood and oxygen to the other organs in the body.

3. Stroke

4. Chronic renal failure or impairment, the failure of the kidney to filter waste and fluid from the blood (hypertension is one of the top 2 reasons for patients requiring renal dialysis)

How do you know if you have hypertension?

Check your blood pressure!

Traditionally, diagnosis is done in the doctor’s office with a blood pressure machine. Doctors then use this measurement to determine whether the patient is at risk of hypertension. However, there is a potential inherent inaccuracy with taking blood pressure the traditional way. The tendency to over-measure the patient’s blood pressure due to:

  • “White-coat” hypertension

Some individuals experience elevated blood pressure when in a medical setting due to the stress or anxiety of being in a doctor’s office. “White-coat” hypertension accounts for almost 20% of the total number of patients diagnosed with hypertension. 

  • Lack of adequate rest before the blood pressure is taken

Sleep helps your body regulate the stress hormones to maintain your nervous system. Lack of adequate rest could affect your body’s ability to manage your stress hormones, hence affecting your blood pressure. 

  • Smoking or caffeine intake before being tested

Smoking and caffeine can immediately raise your blood pressure temporarily, causing an inaccurate diagnosis of your true blood pressure.

How else can you better take your blood pressure?

Diagnosis is no longer limited to being at the doctor’s with the creation of the 24 hours Ambulatory Blood Pressure Measurement (ABPM) and the Home Blood Pressure Measurement (HBPM).

What is ABPM?

ABPM measures your blood pressure for 24 hours as you go about your daily life.


The machine checks your blood pressure every 30 – 60 minutes at fixed intervals and then takes the average.

By measuring your blood pressure over a 24-hour period, your doctor can get a more accurate representation of your true blood pressure throughout the day.

In doing so, it eliminates the risk of “white-coat” hypertension. Your doctor can then prescribe the proper medication for more effective treatment.

What about HBPM?

Most patients who have been diagnosed with high blood pressure should have been advised to monitor their blood pressure at home regularly. 

But I am sure many of us only seriously take our blood pressure the first few days and kick the practice to the curb after. Only to go back to the doctors a few months later and face their wrath for not taking better care of our heart. 

Blood pressure monitoring has never been easier with OMROM bluetooth blood pressure monitoring device and HeartVoice app. Your daily readings can be automatically synced into one app, making active monitoring possible with just a few clicks.

Self-monitoring at home has been shown to be lower than readings taken in the office and closer to the average blood pressure reading during the 24-hour ABPM.

What are the advantages?

  • Multiple readings can be taken over an extended period of time – the more blood pressure measurements, the more accurate the average result will be 
  • Avoid “white-coat” hypertension effect 
  • Ability to predict cardiovascular mobility and mortality much better than office blood pressure taking 
  • Allows the patient to better understand their management – the instant visual change in blood pressure numbers before and after taking their medication acts as a reminder and impresses upon them the importance of medication

However, there are disadvantages . . . 

  • Some home blood pressure monitors have been found to give inaccurate readings 
  • The patient may place the cuff at a position on the upper arm that will affect the accuracy of the readings – hence, it is important to educate the patient on proper cuff placement before he begins home-based monitoring 
  • Risk of treatment change by the patient themselves, based on their home blood pressure without the approval and guidance of the doctor 
  • Lack of nocturnal reading – 10 – 15% of individuals with high blood pressure suffer from night-time hypertension. If left undetected and untreated, they are at a higher risk of heart failure and other complications than those with day-time hypertension.

But, disadvantage does not mean ineffective!

In fact, HBPM is especially useful for anyone diagnosed with high blood pressure to consistently monitor their blood pressure and for those recently beginning with high blood pressure treatment to determine its effectiveness. 

Regular monitoring allows your doctor to adjust your medication as needed to properly treat your condition. 

Incorporating daily readings of your blood pressure – especially those already diagnosed – allows you to identify potential emergency situations and seek help promptly. 

Here’s how you can use blood pressure monitoring to self-diagnose at home! 

The National Institute for Clinical Excellence (NICE) has introduced guidelines one should follow to confirm a diagnosis of hypertension at home:

  • For each blood pressure recording, there has to be 2 consecutive measurements taken, at least 1 minute apart with the person seated
  • Blood pressure must be recorded twice a day – ideally, once you wake up in the morning and at night before you sleep, after resting for 5 minutes.
  • Blood pressure recording should be taken for at least 4 days – although recommended 7 days, of which the readings of the first day should be discarded
  • Take the average value of the readings on the remaining days to determine diagnosis

Hypertension should not be taken lightly.

Even if you are of a young age, it does not mean that you are any less likely to suffer from hypertension than someone in their 70s. Remember, 

90% of the time, hypertension shows no symptoms!

No matter your age, everybody benefits from having a healthy heart. Start taking care of your heart today, before it’s too late!
