Doctors experiences of interruptions in UK secondary care outpatient clinics: a cross-sectional survey of prevalence, consequences and management strategies

In the busy world of a hospital outpatient clinic, a doctor's day is a constant stream of decisions. They must listen to a patient, recall medical history, weigh test results, and plan a treatment, all while the clock ticks forward. This mental effort is not just about thinking hard; it is about how much space that thinking takes up in the mind. Psychologists call this "cognitive load," a concept that suggests our brains have a limited amount of room for new information at any one time. When a doctor is deep in thought about a complex patient, their mental workspace is full. If something unexpected happens—a phone call, a colleague asking a question, or a nurse needing a signature—that extra demand pushes against the limits of that mental space. This is what researchers call an "interruption." While these breaks might seem like minor annoyances, they can force the brain to stop one task, switch gears to handle the new demand, and then try to find its way back to the original work. In a high-stakes environment like healthcare, where a single missed detail can affect a patient's safety, understanding how these interruptions feel to the doctor and how they change the flow of a consultation is vital.

A team of researchers at University College London set out to map this experience across the United Kingdom. They wanted to know how often doctors in secondary care hospitals are interrupted, how much mental strain these breaks cause, and what methods, if any, doctors use to cope. To find out, they sent an online survey to 465 doctors working in various specialties, from surgeons to psychiatrists. The participants ranged from those just starting their careers to those who had been practicing for over fifty years. The researchers asked them to rate their mental workload using a standard tool that measures different types of pressure, such as how hard they have to think, how much time they feel they have, and how frustrated they get. They also asked the doctors to describe how often they were interrupted, how difficult it was to get back to their work after a break, and whether they felt these interruptions helped or hurt their relationships with colleagues.

The results painted a picture of a workplace under constant pressure. More than sixty percent of the doctors said they were interrupted often or very often during their consultations. On average, the doctors reported a high level of mental workload, driven mostly by the need to think hard and the feeling of being rushed. The study found that the more often a doctor was interrupted, the higher their mental workload became. This was especially true for the sense of time pressure; interruptions seemed to eat up time that could not be recovered, making the day feel shorter and more frantic. The complexity of the patients also played a major role. Doctors dealing with patients who had multiple, complicated health issues reported higher mental loads, which makes sense given that these cases require more information to be held in the mind at once. However, the study revealed that the sheer number of interruptions was not the only factor. How disruptive the doctor felt the interruption was, and how hard it was to restart their thought process afterward, mattered just as much.

Perhaps the most surprising finding was that simply having a plan to deal with interruptions did not automatically make the workload easier. About thirty-nine percent of the doctors said they used strategies to manage these breaks, but the researchers found no consistent link between using a strategy and feeling less stressed. When the team looked closer at the written descriptions of these strategies, they found that "managing interruptions" was not a single thing. They identified three distinct ways doctors handled the situation. Some tried to "offload" the task, asking others to wait or writing things down to free up their memory. Others tried to "anticipate" the problem, perhaps by asking a colleague to handle a potential interruption before it happened. A third group used "blunt responses," directly shutting down the interruption, often with a tone of frustration or hostility. The emotional tone of these responses varied wildly. The doctors who used blunt, shutting-down tactics reported feeling more anger and sadness, while those who tried to anticipate and prepare felt more trust and anticipation. This suggests that the way a doctor reacts to an interruption is deeply tied to their emotional state, and that a simple "yes or no" answer about whether they use a strategy misses the whole story.

The social side of these interruptions also proved to be a powerful factor. While many doctors felt that interruptions damaged their relationships with colleagues and made teamwork harder, those who viewed the interruptions as positive social exchanges reported feeling less frustrated and performing better. It seems that if an interruption can be framed as a brief, helpful exchange rather than a rude disruption, it might actually protect the doctor's mood and focus. The researchers noted that experience did not offer the shield many might expect. Doctors with decades of practice did not report significantly lower mental loads than their junior colleagues. This suggests that the environment of the clinic, with its constant flow of demands, affects everyone regardless of how long they have been working. The study concludes that fixing this problem cannot rely on individual doctors trying to be better at coping. Instead, the solution likely lies in changing the system itself. This could mean creating clearer ways for teams to communicate so that necessary information is shared without breaking a doctor's concentration, or designing clinics that allow for protected time to handle complex cases. The goal is not to eliminate all interruptions, which is impossible, but to manage them in a way that respects the doctor's mental space and keeps the focus on the patient.
