Introduction
The changing structure of the global Health System that has moved away from viewing critical care services as exclusively hospital-based to viewing critical care as a primary measure of national resilience has greatly affected the way in which ICUs will continue to evolve. This change can be seen through the combination of many of the clinical, demographic, regulatory, and technological aspects that are now present in the way hospitals build capacity, introduce innovation, and allocate resources. For example, the percentage of hospital expenditures allocated to critical care, as well as the number of ICU beds available, has increased within OECD countries over the last ten years due to a higher level of complexity of patients and longer hospitalization periods with older population demographics.
Likewise, as a continuation of the previous example, there is an increasing number of patients that will survive and continue to live with chronic conditions associated with these types of diseases based upon global population growth patterns. Due to the increasing numbers of patients that die globally from septic shock/sepsis, there is also an increased demand for the products that provide respiratory and renal support for patients who have acute respiratory illnesses, cardiovascular instability, or severe bacterial infections.
With evolving Federal and State governance structures in terms of clinical practice and emerging technologies, governments are investing heavily into building a digital healthcare infrastructure that supports the delivery of critical care services electronically while also improving the speed at which clinical care is delivered, improving patient safety, and improving clinical efficiencies. These governments are also developing new regulations that create a competitive marketplace for the development of AI systems, tele-ICU, and advanced life-support devices in the U.S., EU, and Asia-Pacific.
The ICU market is currently experiencing a transformation from many different directions due to a growing influence of structural, clinical, and technological changes representing the changing nature of critical care in today’s world. A major shift in this sector is the worldwide expansion of high acuity care due to the increasing prevalence of chronic disease. For example, hospitals in many countries in the Organization for Economic Cooperation and Development (OECD) have seen increases year over year in ICU admissions per capita as chronic disease continues to rise. Data from national health systems have demonstrated a steady rise in the percentage of patients who require organ support interventions during their hospital stay, with mechanical ventilation use increasing in numerous geographic areas over the last five years due primarily to an upward trend in respiratory illness, complexity of postoperative care, and the natural aging of the population.
One major trend is the rapid momentum that has been built around digitalization and telemedicine. Global investment by public healthcare systems in tele-critical care is on the increase. Significant improvements have been recorded by multiple large health systems, including the U.S. Veterans Health Administration, in terms of nighttime staff coverage and response times due to the development and deployment of virtual ICU command centers. The European Union and the Middle East also are beginning to adopt similar trajectories for digital health; emerging cross-border digital health frameworks are providing the basis for the establishment of interoperability among multiple hospitals. Government funding directed to predictive analytics, clinical decision support software, and connected device ecosystems are further reinforcing the transition to digital health.
As more countries recognize the need for the ICU community to be prepared for public health emergencies, the trend toward ICU preparedness as a public health responsibility grows. The majority of ICU preparedness programs were created following the impact of the COVID-19 pandemic, and many countries have modified their emergency response programs in response to this experience. New procurement guidelines in many countries now include the elements of equipment redundancy, local manufacturing capacity, oxygen autonomy, and modular ICU capacity. New areas of opportunity are now being opened for vendors to develop portable monitoring solutions, transport ventilators, and deployable negative-pressure environments in order to help meet the needs of hospitals and ICUs worldwide.
The need for advanced infection control systems driven by increased monitoring of antimicrobial resistance continues to push hospitals toward implementing advanced sterilization systems, closed-loop medication management systems, and contactless monitoring systems. Shortages of critical care staff in many hospitals are further accelerating the pace of innovation within the ICU, as increasing use of automation-first technologies to fill void created by shortages of trained intensivists and critical care nurses has easily become the norm.
Growth Parameters Mapped - Drivers
Rapid Population Ageing and Growth of High-Risk Cohorts
There is a Global demographic aging trend that indicates that population aging has put more than considerable pressure on Intensive Care Unit (ICU) services and: The WHO estimates that by 2030, there will be about 1 in 6 people aged 60 and over, resulting in the number of 60+ year-olds worldwide increasing from approximately 1 billion in 2020 and to 1.4 billion by 2030; by 2050, the estimated worldwide population of 60+ year-olds will double to 2.1 billion, and the estimated worldwide population aged 80+ year-olds will triple to approximately 426 million. In other words, the populations of 60+ year-olds and 80+ year-olds will continue to grow at nearly three times the overall population growth pattern. The elderly are also considered to be the most vulnerable populations, or the groups with the greatest potential for developing multiple organ systems failure (MSOF), sepsis and/or pneumonia.
The United Nations Department of Economic and Social Affairs (UN DESA) predicts in its 2023 World Population Aging Report that there are approximately 703 million people aged 65+ worldwide. The 2023 UN DESA report projects that by 2050, it is estimated to be approximately 1.5 billion people aged 65+ worldwide. In many areas, including high-income and upper-middle-income countries, the number of older adults (those aged 65+) is anticipated to be greater than 25% of the overall population. This demographic trend will have significant impacts on the case mix, or types of cases, presented to hospitals, with increasingly higher occurrences of older, frail, multi-morbid patients, and those with high-acuity needs. This trend will continue to impact the demand for equipment such as ventilators, hemodynamic monitors, renal support systems, and structured Geriatric ICU pathways.
Older patients tend to present with combinations of multiple chronic diseases such as coronary artery disease, chronic obstructive pulmonary disease (COPD), diabetes, renal impairment, and neurodegenerative diseases. The WHO indicates that these diseases produce age-related functional impairment, and because of these diseases, as well as polypharmacy and multiple chronic disease conditions, increase significantly the patient's risk of developing serious complications from a severe infection or acute medical event. Older patients tend to be at increased risk of requiring invasive ventilation or use of infusions/hypervolemia, hemodynamic support (vasopressors), and frequent fluid adjustment and continuous monitoring services that are typically provided in ICU facilities.
