Surge in Global Healthcare-Related Harm: What This Study Reveals for Patient Safety

Between 1990 and 2019, the number of people harmed by medical procedures and treatments skyrocketed from 11 million to 18 million worldwide. That’s a 59% increase, which is notably higher than the 45% rise in the global population during the same period. Older adults, particularly those aged 65 to 69, faced the highest rates of these incidents.

In developed countries, over half of these patient harms are considered preventable. In developing nations, that figure jumps to 83%. These incidents not only impact individuals’ health and quality of life, but they also place a significant financial burden on healthcare systems and erode trust in medical institutions.

Current methods for tracking these adverse effects often rely on medical records and voluntary reports. This inconsistency makes it challenging to gather accurate data, which is crucial for shaping health policies. A study used information from the Global Burden of Disease (GBD) project, which assessed health data from 204 countries, hoping to create a clearer picture of patient harm trends.

The analysis indicated that the overall incidence rate of medical harm was about 232.5 per 100,000 people in 2019, growing by 10% since 1990. Notably, richer countries saw a striking increase in these rates, climbing from 515 to 823 per 100,000. France stood out with a decrease in incidents, attributed to a series of effective patient safety policies.

In lower-income regions, however, the overall patient harm incidents dropped by 14%, showing that some improvement is possible even in less affluent areas. Countries like the USA report a significantly higher rate of harm compared to nations such as Indonesia, suggesting that better monitoring in wealthier countries might drive these discrepancies.

The rise in patient harms among older adults can be linked to aging and the complexities of managing multiple medications. As individuals age, their bodies process drugs differently, which can lead to medication errors and complications. Factors like cognitive decline can further complicate adherence to treatment, increasing the risk of harm.

Despite these alarming trends, the study does have limitations. Many lower-income nations lack reliable data, leading researchers to make predictions rather than use concrete numbers. Additionally, the types and severity of harms were not analyzed, which could provide more insight into these trends.

As healthcare systems evolve and populations age, understanding and addressing these adverse effects must be a priority for ensuring effective and equitable healthcare worldwide. Addressing patient harm isn’t just a challenge for individual countries; it’s a global necessity.
