As we stand on the cusp of what could be an era of recurrent pandemics or other healthcare emergencies, there is an immediate need for a rigorous assessment of these digital tools. Our focus here is to scrutinize their capabilities and limitations, providing actionable insights for improving preparedness for future healthcare crises.

Portable Ventilators

Background:?Amidst a surge in ICU admissions, portable ventilators were crucial, particularly in makeshift field hospitals. They provided mechanical ventilation to patients with inadequate respiratory function due to lung injuries or illnesses.

Efficacy:?While saving lives, mechanical failures and operational issues were frequent, partly because of the rush to produce and deploy these devices.

Limitations:?The rapid pace of production led to compromised quality control measures, thereby risking patient safety. Issues have included a lack of proper testing, certification and occasional technical malfunctions. Moreover, there is an additional risk of infection transmission if these devices are not paired with adequate ventilation systems.

Future Prospects: Adhering to international quality standards could significantly enhance the reliability and safety of portable ventilators. Moreover, integrating these devices with Remote Patient Monitoring solutions can improve overall patient care and monitoring.

3D Printing in Healthcare

Background: 3D printing technology has gained prominence in healthcare, notably for rapidly producing personal protective equipment (PPE) and essential medical supplies during the COVID-19 pandemic. The technology involves creating physical objects from digital models by depositing material in layers.

Scalability and Efficacy:?This technology has shown remarkable scalability, fulfilling urgent needs when traditional supply chains faltered. 3D printing applications have spanned the production of face masks, shields, protective eyewear, nasal swabs, and ventilator components. Additionally, physical models of the SARS-CoV-2 virus were created for research and educational purposes.

Limitations:?While 3D printing has demonstrated utility, challenges in material biocompatibility, quality assurance, regulatory compliance, and intellectual property rights remain. There are concerns about the safety and efficacy of 3D printed healthcare products, including potential risks such as infection and malfunction (Health Canada, 2021; FDA, 2021)

Future Prospects:?The advancement in bio-compatible materials and updated regulations could reinforce the legitimacy of 3D printing in healthcare. The technology is promising in personalized medicine, tissue engineering, organ transplantation, prosthetics, implants, and drug delivery systems.

Vaccine Distribution Algorithms

Background: Algorithms have been instrumental in managing vaccine distribution, prioritizing allocations based on factors like age, health status, and geographic location

Adaptability and Efficacy: Dynamic adjustments in these algorithms allow for real-time epidemiological data integration, addressing logistical issues like vaccine availability and storage. An evolutionary algorithm in China notably utilized a fuzzy deep-learning model for demand forecasting.

Ethical Concerns:?Despite their utility, these algorithms have faced criticism for overlooking social and racial equity. A Stanford algorithm notably prioritized administrators over frontline workers, raising ethical questions.

Future Prospects:??There is an increasing need for transparent, ethical algorithms that involve diverse stakeholder input and align with public health goals

Contact Tracing Apps

Background:?Contact tracing apps gained popularity as a tool for managing COVID-19 exposure but eventually faced trust issues. These apps use Bluetooth technology to notify users who have been in proximity to an infected individual.

Initial Uptake:?These apps saw quick adoption and were integrated into broader pandemic response strategies in countries such as South Korea and Singapore. In Canada, the COVID Alert app, launched in July 2020, attracted more than six million users.

Limitations and Failures:?Public trust eroded over time due to concerns about data privacy and false positives. Users became worried about the potential misuse or leakage of personal data, including their location and health status. Additionally, some apps generated false or misleading exposure notifications, creating confusion and concern among users.

Future Prospects: To regain public trust, there is potential for improvement in privacy features and the reliability of information. Apps could employ decentralized and anonymous data storage and encryption methods. Moreover, enhancing the apps with features such as test results, symptom checkers, and self-isolation guidelines could make them more useful.?

Telehealth Platforms

Background:?The pandemic has indisputably catapulted telehealth into the mainstream, transforming it into a staple of modern healthcare. Utilizing technologies like video consultations and remote patient monitoring, telehealth has become a vital component of healthcare delivery.

Surge in Services: Don't underestimate the power of necessity; telehealth has scaled dramatically to fill a void left by reduced physical consultations. Amid the COVID-19 crisis, its usage soared, with a staggering 38-fold increase reported as of July 2021 (Forbes, 2022). This was not a trend—it was a paradigm shift.

Limitations:?While telehealth is revolutionary, it faces tangible challenges. Obstacles like digital inequality, regulatory constraints, and the limitations of remote care for specific medical conditions are all in play.?

Specifically, in Canada, public health policies are still catching up. Several wartime measures, particularly those related to telehealth service reimbursements, have been scaled back or unfavourably modified, putting a strain on service availability. Further, following a virtual consult that requires a specialist, the physician has no insight whatsoever about specialty office capacity and availability proximal to the patient; hence, the physician would have to rely on manual office operations to find a suitable referral destination or pass the patient back into the wild with a referral note and fuzzy next steps.

Nonetheless, these challenges are not insurmountable; they are simply the next set of problems to solve.

Future Prospects: Make no mistake, the future is a blended healthcare model. Telehealth is not here to replace traditional services but to fortify them. Imagine a healthcare landscape where telehealth and in-person consultations coalesce into a seamless, patient-centered care model. That's not a pipe dream; it is an impending reality.

Mental Health Apps

Background:?Make no mistake, the COVID-19 pandemic has unequivocally accelerated the adoption of mental health apps. These platforms offer an expansive array of features, from robust self-assessment tools to peer support and psychotherapy, all aimed at enhancing mental well-being.

Efficacy:?User feedback and empirical studies confirm that mental health apps are effective to a degree. They have been proven to reduce levels of stress, anxiety, and depression for many users. These are not just novelties but serious tools with quantifiable benefits. However, let's be clear: while these apps add value, they have not undergone the level of rigorous testing and validation that professional mental health services have over the years.

Shortcomings:?The evidence is indisputable: mental health apps are not a silver bullet. They cannot, and should not, replace professional diagnostic and therapeutic services.?

Many mental health providers have reported that past the pandemic, most of their patients preferred to revert to traditional in-person care.

Future Prospects: The future of mental health care lies in the seamless integration of both apps and traditional services, not just one or the other. A significant gap exists in connecting the essential elements of a holistic approach to mental health care. Effective treatment often involves a blend of pharmacotherapy and psychotherapy, with ongoing adjustments to medication and therapy. This requires continuous coordination between the prescriber, the primary care provider, and the therapist.

Regrettably, there remains a critical shortage of mental health providers, especially psychiatrists, across the entire spectrum of care. Technology and intelligent program design offer a unique solution to this problem, enabling efficient care escalation. This is achieved by facilitating patient care coordination between readily available professionals like psychotherapists and those less available, such as general practitioners and psychiatrists.

By fusing the convenience of apps with the expertise available through traditional and virtual care channels, we are on the cusp of a revolutionary, holistic approach to mental health care. While this intelligent orchestration of care is not yet widely accessible, it represents the future of effective and scalable mental health care delivery.
