Long-term (14-year) survival after discharge among people with spinal cord injury in Bangladesh
A 14-year cohort study in Bangladesh reveals that among wheelchair-dependent spinal cord injury survivors, long-term survival is poor with a 53% mortality rate, where pressure injuries are the leading cause of death and the standardized mortality ratio remains significantly elevated compared to the general population.

When a person suffers a severe injury to the spinal cord, the damage often stops the brain from sending signals to the body below the point of injury. This condition, known as spinal cord injury, can leave a person unable to walk or control their bladder and bowels. In many parts of the world, the immediate aftermath of such an injury is a race against time in a hospital, but the story does not end when the patient leaves the building. For those who survive the initial trauma and are discharged, the next challenge is living with a new reality for decades. In low-income countries, where resources are scarce and specialized medical care is not always available, the long-term outlook has historically been a mystery. Researchers have long suspected that survival rates in these regions are poor, but without reliable data, it has been difficult to know exactly how many people live long lives and what threatens their safety years after the accident.
A team of researchers set out to solve this mystery by following a specific group of people in Bangladesh for fourteen years. They focused on individuals who had been admitted to the Centre for the Rehabilitation of the Paralysed in 2011 with a recent spinal cord injury. To ensure they were studying the group most at risk, they selected only those who were still dependent on a wheelchair when they left the hospital. This group represents the most vulnerable survivors, as they face the highest risks of complications. The researchers tracked down every single person in this group, or their families, to find out if they were still alive fourteen years later. This level of follow-up is rare; in many studies, people simply disappear from the records, leaving gaps that make the results unreliable. Here, the team accounted for every single participant, creating a complete picture of what happened over more than a decade.
The results revealed a stark reality. Of the 222 people who were alive and in wheelchairs when they left the hospital in 2011, 117 had died by the 14-year follow-up. The researchers calculated that for every year a person in this group was followed, there was a significant risk of death, with the danger being highest in the first year after leaving the hospital. Even fourteen years after the injury, the risk of dying remained much higher than it would be for a person of the same age and gender living in the general population of Bangladesh. The study showed that while the risk decreases slightly over time, it never returns to normal levels.
The most surprising and troubling finding was the cause of death for the majority of these individuals. More than half of the deaths were linked to pressure injuries, also known as bedsores. These are wounds that develop on the skin when a person sits or lies in one position for too long without being moved. In a healthy person, the body shifts weight naturally, but for someone who cannot move their legs or torso, these sores can form quickly. If they become infected, they can lead to severe illness and death. The study found that pressure injuries were responsible for 57 percent of all deaths in this group. Other common causes included problems with the lungs, kidneys, and strokes. This pattern suggests that the primary threat to long-term survival is not the original injury itself, but the complications that arise from a lack of ongoing care and support.
The researchers noted that this group of patients was actually quite privileged compared to others in the country, as they had access to a specialized rehabilitation center that provided education and equipment. Despite this advantage, the survival rate was still low. This implies that for the many people with spinal cord injuries in Bangladesh who never reach such a center, the outlook is likely even worse. The study highlights that the problem is not just the injury, but the system of care that follows it. The high number of deaths from preventable conditions like pressure injuries points to a gap in long-term management. It suggests that if families and communities had better support, training, and resources to help people manage their daily needs, many of these deaths could be avoided.
This long-term study provides one of the most accurate estimates of survival for people with spinal cord injuries in a low-income country. It moves beyond the early days of hospitalization to show what happens over a lifetime. The findings confirm that while medical advances can help people survive the initial trauma, the journey is fraught with danger for decades afterward. The data serves as a clear signal that improving long-term survival requires more than just acute medical treatment; it demands a sustained effort to prevent complications and support individuals and their families in the community. Without these changes, the risk of premature death remains unacceptably high for those living with spinal cord injuries.
