Case report
According to the World Health Organization
(WHO) global statistics as of early January 2024,
>774 million confirmed cases of coronavirus
disease 2019 (COVID-19) and >7 million deaths
have been reported worldwide during the
COVID-19 pandemic.1 At a global level, the
COVID-19 pandemic has now evolved into a steady
state of low-level transmission, with low numbers of
reported COVID-19 cases and deaths. The trend has
been maintained over the past 12 months, despite
a slight increase in the number of reported cases
during the most recent available 28-day period.1
Since the declaration of the Public Health Emergency
of International Concern by the WHO in January
2020, the global pandemic has caused widespread
and devastating economic and social turmoil, along
with extensive disruptions and backlogs affecting
health services in overburdened healthcare systems.
In the early months of the pandemic, global attention
focused on COVID-19 emergency response and
control efforts, such as case identification, contact
tracing, rapid diagnostic tests, and acute treatment.
As understanding has improved regarding the
COVID-19 pandemic and its effects, including post-acute
sequelae of COVID-19 (ie, long COVID), on
all aspects of healthcare,2 3 many countries have
shifted their focus to the establishment of longer-term,
dynamic, and sustained frameworks for health
emergency preparedness, response, and resilience at
national, regional, and global levels.
In the WHO Strategic Preparedness and
Response Plan for 2023-2025,4 a new strategy
consisting of five core components—(a) emergency
coordination; (b) collaborative surveillance; (c) community protection; (d) safe and scalable care;
and (e) access to countermeasures—has been
proposed with a strong emphasis on the mobilisation
of multisectoral partnerships for coordination,
planning, financing, monitoring, and evaluation.
Considering the potential for surges of new variants
with greater severity or transmissibility,5 the updated
WHO framework has been designed and positioned
to maintain sufficient capacity, operational readiness,
and system flexibility to scale up clinical care services
and multidisciplinary team support. This approach
builds on the response-driven pillars outlined
between 2020 and 2022 to address the complex
interactions of COVID-19 with an expanding range of
emerging long-term conditions and circumstances.
Extensive research has been conducted
regarding the effects of public health measures
intended to reduce the risk of COVID-19
transmission.6 The COVID-19–driven changes
and innovations in health practice have also been
captured in past issues of the Hong Kong Medical
Journal.7 In the Greater Bay Area, collaborative efforts
between mainland medical staff and their Hospital
Authority counterparts in a community treatment
facility and large makeshift hospital to combat
the fifth wave of the pandemic have highlighted
the potential for cross-border connectivity and
healthcare integration to benefit residents of Hong
Kong and Macau.7 In addition to government- and provider-level support for the expansion of
community-oriented and patient-centred healthcare
services, there have been dramatic increases in the
use and application of digital health technologies
during the COVID-19 pandemic. Such innovations have also substantially impacted the manners in
which clinical competencies are enhanced, patient
education is delivered, performance parameters
are evaluated, resilience-building environments
are created, and health practices are strengthened.
Studies have shown satisfactory perception and
acceptance of telemedicine consultations among
adults in Hong Kong; telemedicine users reported
positive experiences regarding physician diagnosis,
disease management, and resolution of barriers
to healthcare delivery.8 9 Transformative health
practices empowered by digital technologies,
including (but not limited to) computerised decision
support tools and clinical management systems,
may help to address clinical inertia and workload-related
factors, thereby facilitating efforts to improve
physician motivation and satisfaction in the post-pandemic
era.
The digital technology innovations also
contributed to the understanding of the dynamic
associations between regions with low average
number of daily COVID-19 cases and early public
awareness of WHO-recommended multiple
preventive measures. This has been shown in an
infodemiology study based on Google Trends data.10
The use of publicly available and aggregated
data retrieved from internet searches could offer
valuable insights into population-level behaviours
and their links to the spread of COVID-19 across
different time periods; these insights may support
risk communications, community engagement, and
response coordination.11 Post-pandemic cancer
care delivery should be tailored to accommodate
the diverse unmet needs of patient groups with
different psychological phenotypes, as suggested
by Hong Kong researchers who reported the use of
psychometric analysis as a tool to identify patients
with high risks of decline in physical, psychological,
and dietary wellness.12
In parallel with the explosive spread of
COVID-19 and the persistence of long COVID
symptoms over the past 4 years, the development
of artificial intelligence (AI) technology has
advanced at an unprecedented pace worldwide. In
preventive ophthalmology, there is evidence that
community-based diabetic retinopathy screening via
teleophthalmology, based on imaging examinations
with low-cost devices and remote interpretation, can
serve as an accurate and cost-effective alternative to
conventional face-to-face examinations; it achieves
similar clinical outcomes, broader population
coverage, and timely referral to ophthalmologists,
while maintaining high satisfaction rates.13 This
approach could substantially enhance workflow
efficiency across clinical settings and support clinical
decision-making by determining triage thresholds
and tailoring interventions using predictive analytics.
The use of telemedicine and AI has also received increasing attention; in particular, the
integration of clinical, biological, and genetic
data with long-term health outcomes will help to
elucidate the bi-directional relationship between
COVID-19 and the cardiovascular system.14 The
2023 updated position paper from the Italian Society
of Cardiology and Working Group on Telecardiology
and Informatics has highlighted the considerable
potential of AI-assisted clinical prediction models
in terms of enhancing cardiovascular illness
screening, diagnosis, monitoring, and adverse event
prevention.15 In both ambulatory and inpatient
settings, health practice innovations such as
telemedical care, mobile health applications, and
personalised wearable biosensors play key roles in
efforts to improve clinical decision-making, avoid
unnecessary hospital admission, reduce time to
treatment during cardiac emergencies, rationalise
healthcare services, and promote home care.15
The evolution of COVID-19 demands
sustained global commitment to building a well-prepared,
responsive, and resilient future. This
evolution also highlights the urgent need for
research that addresses the legal, regulatory, ethical,
and reliability challenges involved in transforming
‘big data’ and AI into innovative services that can
be implemented in clinical and real-world settings.
Important and open questions concerning the
management of COVID-19—particularly in relation
to its complex pathophysiology, risk factors, and
effective treatments, as well as long-term vaccine
safety and efficacy (and related issues)—continue to
require multi-channel collection of standardised data
supported by diverse, coordinated, and collaborative
efforts from biomedical and research communities
to inform practice and policy in the new digital era.
