Reasons for medication non-adherence among elderly patients with osteoporotic fractures: A qualitative study using the COM-B model
This qualitative study utilizing the COM-B model identifies that medication non-adherence among elderly osteoporotic fracture patients stems from interactive barriers across capability, opportunity, and motivation domains, including physical limitations, economic constraints, and negative treatment perceptions, necessitating multifaceted interventions to improve adherence and prevent re-fractures.

Every year, millions of older adults suffer broken bones from simple falls, a condition known as osteoporotic fracture. This happens when bones become so fragile that the weight of a standing fall is enough to snap them. While modern medicine offers powerful drugs to strengthen these bones and prevent future breaks, a stubborn problem remains: many patients stop taking their medication. Studies show that between 43 and 64 percent of elderly patients with these fractures do not stick to their treatment plans. This is not just a matter of forgetting a pill; it is a complex puzzle involving how people think about their health, the resources available to them, and their emotional drive to keep going. Without consistent treatment, the risk of a second, often more devastating fracture rises sharply, turning a manageable condition into a cycle of disability and pain.
To understand why this happens, researchers from the China-Japan Friendship Hospital and the Institute of Basic Medical Sciences in Beijing decided to listen directly to the patients themselves. Instead of relying on surveys that count numbers, they conducted a deep, qualitative study, sitting down with fifteen elderly patients who had been admitted to the spinal surgery department with confirmed osteoporotic fractures. They used a framework called the COM-B model, which breaks down human behavior into three parts: capability, opportunity, and motivation. In simple terms, capability asks if a person has the physical and mental ability to do something; opportunity asks if the world around them makes it possible; and motivation asks if they truly want to do it. By exploring these three areas through long conversations, the team uncovered the hidden reasons why so many patients abandon their treatment.
The first major barrier the researchers found was a lack of capability, both physical and mental. Many patients simply could not manage the logistics of their care. Some had lost the mobility to walk to a pharmacy or a doctor's office, while others struggled with memory loss that made it impossible to keep track of multiple daily pills. Beyond these physical hurdles, a deep misunderstanding of the disease itself played a huge role. Most patients viewed osteoporosis as a normal, unavoidable part of aging, like gray hair or wrinkles, rather than a treatable medical condition. This belief led to a dangerous pattern: patients would only take their medicine when they felt pain. Once the pain stopped, they assumed the problem was solved and stopped the treatment. They did not realize that the drug was working silently to prevent the next break, not just to relieve current symptoms. Furthermore, many patients feared the side effects of the medication, such as stomach upset or kidney stones, and chose to stop taking it rather than risk feeling unwell.
Even when patients wanted to take their medicine, the world around them often made it impossible, creating a lack of opportunity. The cost of long-term treatment was a heavy burden for many families, with some patients explicitly stating they could not afford the monthly expenses. For those who could pay, the logistics were still daunting. Getting to the hospital required time and transportation that many elderly people, often caring for grandchildren or dealing with their own health issues, simply did not have. The healthcare system itself contributed to the problem. Doctors in other departments, treating conditions like diabetes or pneumonia, often overlooked the osteoporosis, leaving patients without clear instructions on how to manage their bone health. The community offered little support, with few local lectures or screenings to keep the issue in the public eye. Without reminders from family or community programs, patients easily forgot to refill their prescriptions or lost the routine of taking them.
Finally, the researchers found that motivation was often weak because the benefits of the treatment were invisible. Unlike a painkiller that makes a headache vanish immediately, osteoporosis medication does not produce a noticeable feeling of improvement. Patients could not see their bones getting stronger, and without regular tests to measure bone density, they had no proof that the medicine was working. This lack of visible progress made it easy to prioritize other, more urgent health issues, like high blood pressure, over the silent threat of brittle bones. Some patients also felt a heavy sense of guilt, believing they were a burden to their children, which made them reluctant to spend money or time on their own health. The fear of being a burden, combined with the lack of immediate results, drained their will to continue the treatment.
The study concludes that fixing this problem requires more than just telling patients to take their pills. It demands a coordinated effort to address all three barriers. Patients need better education that explains why they must take medicine even when they feel fine, and they need help managing the physical and mental challenges of daily life. The healthcare system must provide clearer guidance and support, ensuring that osteoporosis is treated with the same seriousness as other chronic diseases. Most importantly, patients need a way to see the results of their efforts, perhaps through regular bone density checks that show them their bones are indeed getting stronger. By understanding the real, everyday struggles of these patients, doctors and families can build a support system that helps them stay on track, preventing the cycle of broken bones and preserving their independence for years to come.
