I would like to again focus on the Hedley Environmental Index Dashboard provided by the University of Hong Kong. The determinants that constitute its success are described as follows,

Data: The dashboard system collects data from surveillance stations in real time and provides updates daily. This makes sure that the data is of high-quality,…[Read more]

I have not worked with a DSS before but I have experienced how it works during treatment. I personally have a drug allergy that is recorded in my EMR. So everytime I go to receieve chemotherapy, the health monitor reads my EMR and would immediately show a big red warning that I have a drug allergy. I think the system is quite useful as it is very…[Read more]

As people above have mentioned, I think the main problem lies with standardization. The ICD helps provide a coding standard in documenting diseases, such that different healthcare providers or peripheral stakeholders such as researchers and insurers could have a consensus of coding in referring to the same disease. If the ICD is not used, there…[Read more]

I am slightly surprised about this finding. I think it is important what we compare it to. Before adopting the EMR, healthcare workers still have to document everything on paper, which is even more time consuming, writing things down and sorting through paper files. I think by standardizing some of the input fields, EMR already helped save time…[Read more]

While the boundaries that define eHealth are blurry and there could be many interpretations and overlaps for its definition, I think my definition would be ‘the use of information technology to enhance health outcomes.’ This is a definition that is easy to understand and overarching enough to cover all kinds of work that is in the field of…[Read more]

An easy example I could think of would be Youtube Videos.

5Vs characteristics (Volume, Velocity, Variety, Veracity, and Value)
Volume: The volume of Youtube videos are enormous. 3.7 million videos are uploaded every day with 200,000+ hours of content.

Velocity: Since videos are constantly being uploaded, viewed, and shared in real-time with…[Read more]

1. Have you ever observed a health informatics project in your (other) organization? Please provide a brief introduction.
The Hong Kong Government has launched a health informatics project known as the Electronic Health Record Sharing System (eHealth) to provide an electronic platform that aims to build free and lifelong electronic health records…[Read more]

I think the advantages are very clear in terms of costs and resources. Since it was given that the hospital does not has an existing system architecture of servers nor the IT staff with expertise, it would have to spend an unimaginable amount of budget to buy all the new servers to host the app and also to hire a big IT team with expertise to…[Read more]

I have personal experience with three kinds of attacks

First is the DDoS attack, which stands for Distributed Denial of Service. For this attack, the attacker usually has control of a “zombie network” of computers, which he could control to send a huge amount of requests to the target, flooding the traffic and thus making the target network no…[Read more]

In Hong Kong, a contact tracing app was launched known as “LeaveHomeSafe”. All citizens are required to scan QR codes when entering public spaces such as malls, restaurants, and government facilities. Anyone found not using the app could be fined. The purpose of the app was to trace everyone that had been at the same location with a potential COV…[Read more]

I did my undergraduate degree in global health, where I was taught about the essentials of management, governance, and policy setting, and I frequently had to research the comparative health policies of different countries. I also did my second major in linguistics where I developed some deep learning language models. So it would appear that I…[Read more]

I think I would consider moving to cloud computing after making a judgment based on the techicalities (the budget, how to migrate/transition the current system to cloud, etc.). Cloud computing can drastically reduce the cost of IT hardware and maintanence, and is a lot more scalable. For example, if we expect a new hospital block to be built in…[Read more]

I will definitely ignore it. I think such scams are very common as pop-ups, even when you go to some reputable websites, these kinds of pop-up ads still exist. Common examples are those saying that your storage is full, your phone is infected with virus, or you are the winner of some big prize. If you believe these messages, you will most likely…[Read more]

While I have never been attacked by serious trojan horses and viruses, my computer was infected with spyware when I downloaded some sketchy Chinese software that was free (I forgot what it was for, but the fact that it could do what I needed made it attractive enough for me to download it). It then hijacked many things in my computer. For example,…[Read more]

I think a dashboard gives healthcare professionals a lot more intuitive view of the general picture and saves them time and effort to try to visualize the data in their brain. Neatly compiled data combined with visual input allows healthcare workers to make quick and informed decisions. For example, if a patient’s information such as his BP or…[Read more]

As a cancer patient myself, I really wanted a social network just for cancer patients, so that we can support each other, talk about our own experiences, and make new friends (very important for me, because my friends all started working after graduation while I am the only one who is staying at home without things to do). People often talk about…[Read more]

Even though I know Javascript is the answer for web apps as mentioned by Nichcha, I think I would use Python as a matter of personal bias. This is because I am already proficient at programming in Python, so I am inclined to use what I already know instead of learning a whole new programming language from scratch (which takes a lot of time!). From…[Read more]

Besides telehealth, I think the Internet has transformed a lot of aspects in health service delivery to make things more reliable and convenient for both workers and patients. In Hong Kong, the traditional way of scheduling a doctor’s appointment is to call in. This is now replaced by apps, where patients could fill in their information and make…[Read more]
