Getting the wires uncrossed
The health system is complex and massive. Digital solutions can enhance service delivery by improving efficiency and increasing effectiveness, which in turn translates to better patient experience, cost savings and reduced carbon emission due to more efficient use of resources.
A good local example is the introduction of electronic medical records in our public health system. The Clinical Management System was launched in 1995, allowing clinical staff access patient data across different specialties and regions within seconds. The program has evolved into a digital platform that integrates information from the public and private sector.
Virtual care has gained much attention during the COVID-19 pandemic. In Canada, the proportion of primary care visits being virtual visits increased from 10-15% to 60% amid the outbreak. Because patients and staff did not need to travel to the same space for a consultation to take place, it was estimated the carbon emission reduction in 2020 was equivalent to taking 61,000 cars off the road for an entire year. Local studies in Hong Kong found patients received earlier medical attention with the use of telemedicine, leading to shorter waiting time for new case referrals, less emergency hospital attendance and shorter hospitalization days. This model of care has been welcomed by patients and their carers, mainly due to its convenience.
By harnessing the technological power,
the possibilities are endless
Another technological advancement is the hospital capacity management command center, typically focusing on bed management. The system helps getting beds ready and allocated to admitted patients, and removing barriers to discharge when a patient is ready to leave, reducing the wait-around time. It is comprised of a wall of analytics, where real-time data from multiple source systems across the hospital is displayed, and triggers coordinated action from staff of various disciplines stationed within the command center. Advanced algorithms can anticipate and resolve bottlenecks in care delivery, allowing better resource allocation and smoother patient journeys. By reducing system-wide inefficiencies, excess hospitalization days can be eliminated.
By harnessing the technological power, the possibilities are endless. Big data can be utilized to understand trends and trigger preemptive action. Integrating technology to supply chain organization can improve stock management and reduce wastage. The general public can monitor their health data trends with apps and modify their behaviour according to the feedbacks, empowering citizens to take care of their own health.
While such advancement is exciting, it is important to acknowledge that data demand and digital equipment constitute carbon footprint as well. Emission and pollution are associated with the manufacturing, distribution, operation and disposal of these equipment. To reduce the environmental impact of digitalization, we can:
-
Use energy consuming devices responsibly, including reducing excessive brightness of screens, switching off the devices when not in use, using smaller devices when possible (smartphones vs tablets vs desktop computers)
-
Use more energy-efficient equipment
-
Recycle or reprocess devices instead of disposing them
-
Advocate for a societal shift to clean energy
-
Embrace integrating technology into care pathways
-
Purchase environmentally-preferrable electronic products, in terms of energy efficiency, inherent carbon footprint, green disposal
-
Use energy responsibly, such as reducing screen brightness according to ambient light, and switching off devices when not in use
Some practical ideas
Successful stories
Healthcare at a distance
The community geriatric assessment team (CGAT) at Shatin Hospital trialed teleconsultation at a 200-bed nursing home in 1998 - 1999. Videoconferencing units were installed at the nursing home and Shatin Hospital. 1001 teleconsultations were made.
Productivity gains:
shorter waiting times for new referrals, more frequent review of old cases, increased total case-load
8.8% reduction in emergency hospital attendances, 10.6% reduction in hospitalization bed-days at the acute hospital
Service favoured by 96% of resident respondents
Nursing home staff felt more confident in caring for residents, and partnership between institution and CGAT is strengthened
Saved cost of HK$ 236,451
Clinical command center
Tampa General Hospital in the US launched a clinical command center in 2019. A multidisciplinary clinical team utilizes artificial intelligence and predictive analytics to coordinate patient care and reduce system-side inefficiencies.
Eliminated 20,000 excess patient days, reduced average length of stay by half a day
Additional 30 bed capacity without adding beds
Reduce emergency room diversion by 25% for the level one trauma center
