Empowering Singaporeans to better manage chronic heart failure: Protocol for a mixed-methods study
This protocol outlines a mixed-methods study in Singapore that employs a systematic review, qualitative interviews, a discrete choice experiment, and a cost-effectiveness analysis to develop and evaluate a contextually suitable, patient-preferred, and cost-effective empowerment-based intervention for managing chronic heart failure.

Chronic heart failure is a condition where the heart struggles to pump blood with enough force to meet the body's needs. It is not a sudden event like a heart attack, but a long-term state that often worsens over time, leading to frequent hospital visits, high medical costs, and a significant reduction in a person's quality of life. As populations age and lifestyle factors change, the number of people living with this condition is growing, placing a heavy strain on healthcare systems worldwide. In response, doctors and researchers have increasingly turned to the idea of patient empowerment. This approach does not simply tell patients what to do; instead, it provides structured support to help them understand their condition, build the skills to manage it, and actively participate in decisions about their care. The goal is to shift the dynamic so that patients feel capable of taking charge of their daily health routines, rather than feeling passive recipients of medical instructions.
In Singapore, a team of researchers is working to determine exactly how to design such an empowerment program for heart failure patients so that it fits the local culture and offers good value for money. They are not yet testing a specific treatment on patients, but rather mapping out a comprehensive plan to find the best possible approach. Their work is a multi-stage investigation that begins by looking at what has already been discovered globally, then listening closely to the experiences of local patients and their families, and finally using that information to predict which combination of support features would be most effective and affordable. The researchers are building a roadmap to create a tailored intervention that respects the unique social and medical landscape of Singapore, ensuring that the solution is not just theoretically sound, but practically useful for the people who need it most.
The first step in this journey involves a systematic review of existing scientific literature. The team is gathering and analyzing studies from around the world that have tested various empowerment programs for heart failure patients. They are looking specifically for evidence on whether these programs help patients live better lives, stay out of the hospital, or reduce medical costs. By focusing on studies published since 2020, they aim to capture the most current and relevant findings. This global survey of evidence will help them understand which types of support have worked elsewhere and which have not, providing a solid foundation of international knowledge before they turn their attention to the local context.
Once they have a clear picture of the global evidence, the researchers will shift their focus to the people living with heart failure in Singapore. They plan to conduct in-depth, one-on-one conversations with thirty to sixty patients and thirty to forty-five of their caregivers. These interviews will be conducted in English, Mandarin, Malay, or Tamil, depending on the participant's preference, to ensure that language is not a barrier to sharing their stories. The goal is to understand how these individuals experience their condition, what kind of help they feel they need, and what obstacles stand in the way of managing their health effectively. By listening to patients and families from different backgrounds and age groups, the researchers hope to uncover the specific cultural and practical nuances that a successful program must address.
The insights gained from the literature review and the local interviews will then be used to design a special survey known as a discrete choice experiment. In this survey, patients will be asked to make a series of hypothetical choices between different versions of a support program. Each version will offer a different mix of features, such as the frequency of check-ins, the type of information provided, or the level of involvement from family members. By observing which features patients consistently choose over others, the researchers can determine exactly what matters most to them. This process helps to quantify preferences, revealing whether patients would rather have more frequent contact with a nurse or more detailed educational materials, for example. It allows the team to build a program that is not just based on what doctors think is best, but on what patients actually want and are willing to use.
Finally, the team will use all the information gathered from the previous steps to run a computer simulation that estimates the cost and effectiveness of the proposed intervention. They will model how the program would perform over a ten-year period, comparing the costs and health outcomes of patients who receive the new support against those who receive standard care. This simulation will take into account factors like how many people are likely to join the program and how well they will stick to it, based on the preferences revealed in the earlier survey. The ultimate goal is to calculate whether the investment in this empowerment program would be worth it for the Singapore healthcare system, ensuring that the final design is not only patient-centered but also economically sustainable.
Throughout this entire process, the researchers are guided by a commitment to rigor and transparency. They have established clear rules for how they will select studies, interview participants, and analyze data to ensure their findings are reliable. They are also paying close attention to ethical considerations, ensuring that all participants give informed consent and that their privacy is protected. While the study is still in progress, with data collection expected to finish in early 2027, the methodical approach they are taking promises to deliver a clear and actionable answer. By combining global evidence with local voices and economic modeling, this project aims to create a blueprint for a heart failure support system that truly empowers Singaporeans to manage their health with confidence and dignity.
