Acceptability of community health worker-led hypertension care with independent prescribing in rural Lesotho: a mixed- methods study
This mixed-methods study demonstrates that community health worker-led hypertension care with independent prescribing, supported by a mobile clinical decision support system, is highly acceptable to patients in rural Lesotho, driven by trust and convenience despite minor concerns regarding confidentiality and interpersonal dynamics.

High blood pressure is a silent force that damages hearts and vessels, leading to millions of premature deaths every year. While effective medicines exist to control it, many people in rural areas never receive them. The barriers are often simple but insurmountable: the nearest clinic is a day's walk away, transport costs are too high, and there are not enough trained doctors to see everyone. To solve this, health systems have turned to community health workers. These are trusted neighbors who live in the villages they serve, already known for helping with vaccinations or maternal care. For decades, the standard approach has been to let these workers check blood pressure and remind people to take their pills, but to leave the actual prescribing of medicine to nurses or doctors at a distant clinic. This study asks a bold question: what if these trusted neighbors were trained and equipped to prescribe the medicine themselves, right there in the village?
In the rugged, mountainous countryside of Lesotho, where two-thirds of the population lives in remote villages, researchers tested this idea. They worked with a large group of adults who had high blood pressure. In some villages, the usual system remained in place, sending patients to clinics. In others, community health workers took on a new role. These workers were given special training and a mobile phone application that acted as a digital guide, helping them decide exactly which medicine to give and how to adjust the dose based on the patient's readings. The workers could start treatment, change the dosage, or stop it entirely, all without needing to call a doctor first. The goal was to see if this model was not only safe and effective, but also something the people would actually trust and accept.
The researchers asked hundreds of participants to share their thoughts after living with this new system for over a year and a half. They found that the answer was a resounding yes. More than 97 percent of the people surveyed said they found the care acceptable. Even more striking, nearly 97 percent said they would recommend this approach to others. The participants did not just tolerate the change; they embraced it. They described feeling comfortable and confident receiving medicine from a neighbor they knew, someone who lived in their village and could visit them at home. One participant noted that they felt safe because the worker was local, and another mentioned that help was available even in the middle of the night.
The appeal of this model lay in its simplicity and proximity. For the first time, people did not have to leave their homes to get their blood pressure managed. They saved money on transport and avoided long waits in crowded clinics. The digital guide on the worker's phone was also a key factor in building trust. Participants understood that the worker was not acting alone but was following a strict set of rules and had support from supervisors. This structure reassured them that the care was safe, even though the person handing them the medicine was not a doctor. The study showed that when the system is set up correctly, with proper training and digital support, people are willing to trust their neighbors with serious medical decisions.
However, the study also uncovered the human side of this arrangement. While almost no one doubted the worker's medical skill, some people worried about other things. The most common concern was not about competence, but about relationships. A few participants worried that a personal or family disagreement with their worker might affect their care. Others were concerned about privacy, fearing that neighbors might find out they had high blood pressure. These issues were not about the medicine itself, but about the social fabric of the village. The researchers noted that for this system to work on a larger scale, it would need to handle these interpersonal dynamics carefully, ensuring that confidentiality is protected and that people have other options if their relationship with a specific worker becomes difficult.
The study also revealed that the path to care was not always a straight line. Some people started with the community worker and stayed with them. Others began at the clinic and later moved to the worker. Some switched back and forth depending on their health needs or their ability to travel. This fluidity showed that people did not see the community worker and the clinic as enemies, but as parts of a single system that could adapt to their changing lives. When someone felt too sick or needed complex care, they could go to the clinic. When they needed convenience, they could stay with the worker. This flexibility was a major strength, allowing the system to serve people where they were, both physically and medically.
Ultimately, the research demonstrates that the boundaries of what a community health worker can do are wider than previously thought. In a place where doctors are scarce, these trusted neighbors can safely manage high blood pressure, including the critical task of prescribing medicine. The high level of acceptance suggests that this model is ready to move beyond a research project and become a real part of daily life for millions of people. It offers a way to bring essential care to the doorstep of those who need it most, provided that the system remains attentive to the trust and relationships that hold the community together.
