The Impact of Data Science on Healthcare in Hong Kong

Data science is a field that draws on statistics, mathematics, programming skills, and subject expertise to analyze and extract valuable insights from data. It can help companies improve operational tools, find new business opportunities and make more informed decisions.

For example, Google can predict flu outbreaks by analyzing people’s search queries. This helps authorities take precautions and prevent the spread of flu.

1. Patient Monitoring

Data science has sparked the development of patient monitoring tools that allow doctors to detect diseases and their symptoms earlier with minimal or no human intervention. This has resulted in better treatment outcomes and reduced medical costs.

During the SARS outbreak, public perceptions and behaviours towards the disease evolved rapidly and Hong Kong residents quickly adopted appropriate SARS prevention measures. Perceptions of risk in crowded places and public transport closely followed the number of reported cases-rising during the early phase and declining in later phases of the epidemic.

While household crowding is a strong predictor of poor health in some developed countries, its impact on healthcare demand remains largely underestimated by policy makers in Hong Kong. It is therefore important that it be made one of the consistent equity stratifiers for all healthcare surveys. This will provide a more accurate picture of health inequalities and help inform policy making. This is especially critical during a pandemic.

2. Predictive Analysis

Whether it is cell phone records, social media updates or e-commerce purchases, all sectors are racing to digitize any information they can. This constant stream of Data HK has led to the emergence of new fields of study and operational tools for every sector.

One of these is predictive analysis. Correlational analysis can identify patterns in a dataset to predict the future. It can be applied to any system, from car maintenance to the human body. A good example is Google Flu Trends which aggregates search terms to forecast influenza activity in real-time.

This type of data analytics is used in healthcare to help reduce waiting times, improve workflows, and ensure that patients receive the correct medication. For instance, a wearable device can detect an anaphylactic allergic reaction in real-time and deliver life-saving epinephrine automatically. This can help lower costs and reduce the need for hospital stays. In fact, one study showed that an algorithm was able to diagnose stage 0 breast cancer more accurately than human doctors.

3. Medical Applications

Using data science tools, healthcare professionals can easily extract information from the huge amounts of structural and unstructured data generated by medical systems. This data is a valuable asset for the medical industry as it can be used to improve patient outcomes and reduce medical costs.

One of the many uses of data science is to identify gene mutations that can lead to various diseases. In addition, it can also be used to develop new drugs and screening techniques.

Another example is the use of radiological modalities to monitor and detect aging-related chronic diseases like cardiovascular disease, neurodegenerative disorders, and cancer. Early detection and diagnosis enables better treatment and can prevent complications.

The adoption of eHR is a strategic 21st-century step towards making healthcare more modern, efficient and cost-effective. Nevertheless, it is important to reconcile patients’ legitimate concerns over privacy with the usage of healthcare technology to enhance health sector performance and population health. Stringent security measures are essential to protect patient data from being misappropriated, misused or lost.

4. Artificial Intelligence

AI has the potential to make healthcare more personalized, predictive, preventative and interactive. However, several obstacles remain at all levels of AI adoption. These include data collecting, technological development and clinical application. Furthermore, the ethical and societal concerns must be addressed.

For example, the Hong Kong-based biotech CK Life Sciences is developing an AI-powered cancer vaccine research platform. This solution will enable physicians to diagnose and treat patients in a more efficient manner. It will also help to alleviate the problem of a limited number of medical resources by prioritizing care for the most vulnerable patients.

Moreover, software platforms powered by artificial intelligence can provide healthcare organizations with real-time reports and metrics on resource usage and identify situations and seasons where scaling up is required. This will save valuable time and effort. Ultimately, AI-powered predictive modeling will also allow for a more accurate forecast of future demand and ensure that healthcare is able to continue its mission of improving health outcomes for all.
