Geographic and behavioural determinants of healthcare facility choice among hypertensive patients in urban South India: a cross-sectional study
This cross-sectional study of hypertensive patients in urban South India reveals that facility choice is driven more by transport access, continuity of care, and residential location than by proximity alone, with the majority of patients bypassing their nearest government primary health centre in favor of higher-level or private institutions.

In cities across the developing world, a quiet tension exists between where people live and where they go for medicine. Public health systems are designed with a simple logic: a clinic should be built near a neighborhood, and the people living there should walk to it for their daily needs. This idea, known as a catchment area, assumes that distance is the primary force guiding a patient's choice. If a doctor is nearby, the patient will go there; if the doctor is far away, the patient will stay home. However, the reality of how people actually behave is far more complex. In the study of health geography, researchers look at how physical space, the availability of transportation, and the habits of daily life shape the decisions people make when they are sick. They ask whether a patient's location on a map truly dictates their path to care, or if other invisible forces—like trust in a specific doctor, the ability to afford a bus ticket, or the desire for a higher level of expertise—pull them in different directions. Understanding this is critical because when patients skip their nearest clinic to travel to a distant hospital, it can overwhelm the larger facilities while leaving the smaller ones empty and underused, creating a ripple effect that strains the entire system.
A team of researchers set out to map this invisible journey in Mysuru, a city in southern India, focusing on people living with high blood pressure. Hypertension is a condition that requires steady, long-term management, making it a perfect subject to study how people interact with their healthcare system over time. The researchers gathered information from 503 adults who had been diagnosed with high blood pressure and were actively seeking treatment. They did not just ask these patients where they went; they used technology to pin down the exact location of every patient's home and the exact location of every clinic or hospital they visited. By drawing straight lines between these points on a digital map, the team could calculate the precise distance each person traveled, removing the guesswork from self-reported answers. They then compared these real-world paths against the theoretical ideal: did the patients go to the government-run primary health center closest to their front door, or did they bypass it to go somewhere else?
The results revealed a striking pattern of movement that defied the simple logic of proximity. Contrary to the expectation that people would stick to the nearest option, 85 percent of the patients in the study did not visit the government primary health center closest to their home. Instead, they traveled to other facilities, often skipping the nearest one entirely. This behavior, known as bypassing, was not random. The study found that having a personal vehicle was a major factor; those who owned a car or motorcycle were significantly less likely to bypass their nearest clinic, suggesting that when people lack personal transport, they are more likely to bypass the nearest option, perhaps because they cannot easily reach it or rely on other factors to guide their choice. Conversely, those who had a regular follow-up routine with a specific doctor were much less likely to bypass their nearest facility, highlighting that trust and continuity often matter more than raw distance.
Interestingly, the study also uncovered what distance actually controls. While the distance a patient traveled did not seem to decide whether they chose a government clinic or a private one, it did strongly predict the level of care they sought. For every additional kilometer a patient traveled, their likelihood of going to a secondary or tertiary hospital—a facility equipped for more complex cases—increased significantly. This suggests that patients are willing to travel further when they believe they need a higher level of expertise, but they do not necessarily travel further just to switch sectors. The data showed a sharp drop-off in how often people traveled as the distance increased; for every kilometer added to the trip, the number of visits fell by approximately 43%. This "distance decay" meant that most care was concentrated very close to home, yet a significant portion of the population was still making long journeys. In fact, nearly half of all the visits in the study were concentrated at just three facilities: a government urban health center, a district hospital, and a private urban health center.
The researchers also discovered that where a person lived mattered more than their individual characteristics. Patients living in the same apartment building or housing cluster tended to make the same choices, traveling to the same facilities and bypassing the same clinics. This clustering accounted for a large portion of the variation in behavior, indicating that the neighborhood environment itself shapes health decisions in ways that individual factors like income or education cannot fully explain. The study concluded that the standard way of planning healthcare—drawing circles around clinics and assuming everyone inside will come in—does not match the reality of urban life. In this setting, facility choice was driven by access to transport, the stability of a relationship with a doctor, and the specific needs of the patient, rather than by the simple fact of who is closest. The findings suggest that to improve care for conditions like high blood pressure, health planners may need to focus less on building more clinics and more on ensuring that patients can easily reach the ones that already exist and that they trust.
