More than 2 billion people worldwide lack access to surgical services
ScienceDaily (July 5, 2010) More than two billion people worldwide do not have adequate access to surgical treatment, according to a new study from the Harvard School of Public Health (HSPH). The researchers also found that people living in high-income regions have far greater access to operating theaters (surgery sites) than those living in low-income regions and that surgical facilities in low-income settings often lack essential equipment.
A substantial amount of the global burden of disease comes from illnesses and disorders that require surgery, such as complicated childbirth, cancer and injuries from road accidents. The burden of treating surgical conditions is especially acute in low-income countries. The wealthiest third of the global population undergoes 75% of the estimated 234 million surgical procedures done each year, the poorest third just 4%.
“Our findings suggest that high-income regions have more than 10 times the number of operating theaters per person than low-income regions,” stated Luke Funk, research fellow in HSPH’s Department of Health Policy and Management and a surgical resident at Brigham and Women’s Hospital in Boston. “Addressing this disparity will be a large challenge, but global public health efforts have had a profound impact on other major sources of morbidity including malnutrition, infectious diseases, and maternal and child health. The same could be accomplished for surgical care.”
The study appears on-line July 1, 2010, on the website of the journal Lancet and will appear in a later print issue.
The researchers, led by Funk and senior author Atul Gawande, associate professor in HSPH’s Department of Health Policy and Management and a surgeon at Brigham and Women’s Hospital, obtained profiles of 769 hospitals in 92 countries participating in the World Health Organization’s Safe Surgery Saves Lives initiative, which aims to reduce surgical deaths and is led by Gawande. Based on the profiles they calculated ratios of the number of functional operating theaters to hospital beds in seven geographical regions worldwide. The researchers used pulse oximetry, a monitor that measures the amount of oxygen in patients’ blood during surgery and an essential component of safe anesthesia and surgery, as an indicator of operating theater resources.
The results showed that all high-income regions had at least 14 operating theaters per 100,000 people. In contrast, those in low-income regions had less than 2 operating theaters per 100,000 despite having a higher burden of surgical disease. In addition, pulse oximetry was unavailable in almost 20% of the operating theaters worldwide and absent more than half the time in low-income regions. The researchers estimated that around 32 million surgeries are performed each year without pulse oximetry, a basic standard of care that is available in more than 99% of operations done in high-income regions.
According to Gawande, “It is not news that the poor have worse access to hospital services like surgery. But the size of this population is a shock. Our findings indicate that one third of the world’s population remains effectively without access to essential surgical services–services such as emergency cesarean section and treatment for serious road traffic injuries. Surgery has been a neglected component of public health planning and this clearly needs to change.”
The study is an important step in understanding the critical need for better access to surgical services and for safer operations in low-income settings worldwide. “It is important for the public health community to close the gaps between rich and poor regions if it wants to address the burden of surgical disease in developing countries,” stated Funk. “This will become even more important in the next several decades as chronic diseases — which are often surgical conditions — increase with the aging of the global population.”
Support for this study was provided by the World Health Organization.
