1. How do you define precision medicine, and why is it considered a game-changer in modern healthcare?
Precision medicine is the future of healthcare. It would empower our providers with precise information and data to offer consultation, counselling, and treatment personalised and targeted to the person based on their unique genetic makeup, lifestyle, and environment. It opens a totally new avenue for providers to shift from the traditional one-size-fits-all approach towards a more personalised and preventive model of care.
Precision medicine is opening the floodgates in modern medicine to empower patients, personalising prevention, offering effective treatments, and, most importantly, reducing healthcare costs by being efficient and targeted, thus minimising wastage and potentially avoiding unnecessary treatments and hospitalisations.
2. What role does AI play in the development and implementation of precision medicine?
AI is the premium enabler and the engine powering the development and implementation of precision medicine. Precision medicine depends on big data analytics and algorithms to analyse the vast amount of complex genetic data, medical records, personal history, and determinants of health to lead to more personalised and effective treatments ultimately. With AI and the power of computing, we can now dive deep with speed to analyse drug discovery and development in clinical trials and medical imaging offerings, which are all the developing prospects of AI in precision medicine. Now, with Generative AI enveloping the transformation at breakneck speed, we are previewing the further offerings of a powerful new force in precision medicine, adding another exciting intelligence layer to the already transformative role of AI in this field. Generative AI is poised to be a game-changer in precision medicine, potentially and significantly revolutionising healthcare delivery and checking the rising cost by improving efficiency and accuracy.
3. Can you discuss some of the key benefits of precision medicine for patients compared to traditional treatment methods?
By using precision medicine for treatments, the treatment protocol shifts from the "one-size-fits-all" traditional approach, which could lead to treatments that may be ineffective or even harmful for some patients. Precision medicine minimises the risk of side effects, improving the overall treatment outcome by allowing the treating doctor to provide precise information about the patient, which was not available in the traditional space. It is also a patient-centric approach that personalises the treatment.
4. How does the integration of genetic information, medical records, and lifestyle factors contribute to the success of precision medicine?
Patient-centric medicine should be practised for the optimum benefit of the patient, and that should be value-based. Its success depends on comprehensive personal history (lifestyle factors), including family history and review of past medical records. Integrating genetic information is the icing on the cake for precision medicine, which takes a whole new holistic approach in tailoring the treatment to the individual.
5. What challenges do healthcare providers face when implementing precision medicine, and how can they be overcome?
Costs are a major challenge for healthcare providers when practising precision medicine. Precision medicine is driven by technological innovations, including the availability of genetic screenings and analytics to empower it. As precision medicine is in the developmental stage that is making unsurmountable progress, precision medicine treatments can be expensive and not available or accessible. To overcome these challenges, the initial stage would be for the government and public policymakers to invest in research and development of affordable precision medicine therapies and diagnosis, focusing initially on non-communicable diseases that consume almost 70% of the healthcare budgets globally.
6. Can you share some success storeys or case studies where precision medicine has significantly improved patient outcomes?
Cancer care has been at the forefront of offering precision medicine, and one good example is the discovery of the HER2 gene mutation, which led to the development of Herceptin. This targeted therapy has significantly improved survival rates for women with this specific form of breast cancer. In my experience working with doctors on genetic screening results for patients, we could precisely diagnose and offer treatment plans with supplements and lifestyle modification with targeted nutrition regimes to treat the conditions.
7. How do you see the role of precision medicine evolving in the next five to ten years, particularly in Malaysia?
I believe precision medicine will become a mainstream treatment protocol in Malaysia in the next five to ten years, a parallel development globally. Oncologists from several leading hospitals in Malaysia have been at the forefront in the last ten to fifteen years, offering precision medicine as targeted therapies as part of their cancer treatment options.
Cancer Research Malaysia is at the forefront, the first in Asia to collaborate with geneticists, gynaecologists, and oncologists to complete a study that began in 2017 for mainstream genetic counselling for genetic testing of BRCA1 and BRCA2 in ovarian cancer patients in Malaysia. The study has had a positive impact and has proven feasible for addressing the increasing need for genetic services in Malaysia and other Asian countries.
Many private companies in Malaysia are already offering genetic screenings, and the awareness among medical professionals is growing, especially with wellness and functional medicine clinics. This augurs well for precision medicine's growth in Malaysia as it takes its position in mainstream medicine practise. Moving forward, Malaysia needs greater participation from the public sector, especially to enhance primary and preventive care.
8. How can healthcare policies and regulations support the advancement of precision medicine?
Foremost, we must educate healthcare students and healthcare professionals on the latest developments in precision medicine. This requires funding as the government initiative to support the development and implementation of the training programmes. Technological advancement, especially in AI, greatly outpaces government-supported policies and regulations. This can create uncertainty and hinder the integration and adopting of new technologies like AI and genomics into mainstream healthcare.
The initial steps should be geared towards supporting the private sector's initiatives in developing precision medicine to empower healthcare professionals. I am reemphasising the importance of education and training, which does not consume big budgets. Only having healthcare professionals onboard would be the next step in implementing precision medicine as the treatment protocol for all providers.
This is the future of healthcare, and it promises to address many of its challenges. Thus, policies and strategies to cultivate a workforce of healthcare professionals with the knowledge and enthusiasm to embrace precision medicine will pave the way for its wider adoption and integration into standard treatment protocols, ultimately improving healthcare delivery for all.
9. What are the ethical considerations involved in precision medicine, especially regarding genetic data privacy?
As with any digital and data item, it raises ethical questions, particularly regarding genetic data privacy. The primary concern is who owns your genetic data and how it is stored and secured. The many recent data compromises, even from the high-security digital chambers, raise many concerns among healthcare professionals and patients. Data privacy is a work in progress that will continue and should be supported. However, it should not hinder or slow the adoption of precision medicine and implementation as the benefits to the population are overwhelmingly positive and are the pathway to improving the current disease burden and challenges.
Genetic information can imply potential discrimination, such as denying insurance coverage or employment opportunities. It could also result in social stigma, knowing your genetic predisposition for diseases, and result in psychological distress. While one standard solution commonly practised would be to strengthen the data privacy laws, a more engaging approach will be to raise public awareness about genetic privacy rights and empower individuals to make informed decisions about their data. We should address these ethical concerns to build trust and ensure responsible and equitable development of precision medicine.
10. How can healthcare providers ensure that precision medicine is accessible and affordable for all patients, regardless of their socioeconomic status?
This is a very challenging situation. It is only applicable to healthcare providers from the public sector. Private healthcare is driven as a business, sometimes with very minimal social elements infused. Thus, public policy should be in place for patients from lower socioeconomic status to gradually introduce precision medicine with the appropriate budget. In the long-term, investing in precision medicine will reap the benefits of better healthcare and reduce the cost of healthcare for severe chronic diseases that consume a major part of the budget.
For providers in the private sector, where most patients are insured, it is timely for insurers to consider the importance of precision medicine positively as the pathway to manage increasing healthcare costs. One potential model is shifting healthcare reimbursement towards rewarding positive patient outcomes (value-based). This will incentivise cost-effective treatments, including patients receiving precision medicine that improves patients' health and reduces long-term costs.
Precision medicine is evolving very fast, and the costs are reducing. With more healthcare providers adopting it (volume), the cost will decrease further and make it affordable for all categories of patients irrespective of their social status. Technology in areas like gene sequencing and AI analysis is improving rapidly, which will impact the overall cost of precision medicine. Let's hope this will come forth faster than we anticipate to move closer to a future where personalised healthcare is the norm for all.
11. In what ways can precision medicine contribute to preventive healthcare and the early detection of diseases?
I am glad we are in the era witnessing the groundbreaking developments in genomics. All of us are born with unique genetic makeup, our building block that predisposes us to certain diseases. Having this knowledge from the early stages of our lives gives us the opportunity to understand our health disposition and plan our lifestyles to focus on preventive health and wellness.
It is important to note that understanding your unique genetic profile helps the individual process this information and make informed decisions. Thus, precision medicine is an enabler to kick-start your journey to "take charge of your health" and plan for optimal health and well-being.
12. How can education and training programmes for healthcare professionals be adapted to include the principles and practises of precision medicine?
The principles and practise of precision medicine should be brought into the mainstream of medical schools' curriculum immediately. With the pace at which this future of medicine is evolving, medical students should be exposed in-depth to genomics, precision medicine principles, and ethical considerations of using patient data. Future healthcare professionals should be equipped with basic skills in interpreting genetic results using AI-powered tools to provide consultation and counselling. They should be prepared to embrace precision medicine in their practise for treatment.
For practising healthcare professionals, tailored training programmes on precision medicine should become a mainstream subject in seminars, workshops, and conferences as a continuous learning module. By integrating these training strategies, we can equip healthcare professionals with the knowledge and skills needed to deliver personalised and effective care using the tools of precision medicine. We empower the professionals, leading to better patient outcomes and a more efficient patient-centred healthcare system.
