Global healthcare spending is projected to reach 1.6 trillion by 2030, but outcomes remain hard to shift. In 2019, air pollution was linked to 10 million deaths, and hypertension affected 29.7% of the world’s population. HIV/AIDS still contributed an estimated 1.3 million deaths in 2022, alongside rising cyber risk where 47% of healthcare organizations reported ransomware as the most common threat in 2023.
