Neighborhood Disadvantage and Same-Day Surgical Cancellation in Children: A Multispecialty Cohort Study

Imagine a child scheduled for a necessary surgery, one that has been planned for weeks. The family has taken time off work, arranged childcare for siblings, and prepared the child for the procedure. Then, on the morning of the operation, the hospital calls to say the surgery is canceled. This disruption is not just an inconvenience; it is a source of financial strain, emotional distress, and lost trust in the medical system. For years, doctors and hospital administrators have known that these last-minute cancellations happen more often for some families than others. The question has long been why. Is it simply that certain neighborhoods lack resources, or is there something deeper about who the patient is that drives these outcomes?

Researchers at a large children's hospital in Wisconsin set out to answer this by looking at the link between where a family lives and whether their child's surgery gets canceled on the day of the procedure. They focused on a concept called social vulnerability, which measures how much a neighborhood struggles with things like poverty, lack of education, and limited access to transportation. They also examined how race plays a role, knowing that in the United States, race and neighborhood disadvantage are often deeply connected. By studying tens of thousands of scheduled surgeries over five years, the team wanted to see if living in a disadvantaged area made a cancellation more likely, and if being Black remained a risk factor even after accounting for where a family lived.

The study looked at 72,489 elective surgical appointments for children between 2020 and 2025. These were planned procedures, not emergencies, spanning eight different surgical specialties from heart surgery to ear, nose, and throat operations. The researchers matched each child's home address to a national map of social vulnerability, which ranks neighborhoods based on census data. They then tracked what happened to every scheduled surgery: did it go ahead as planned, was it canceled days before, or was it canceled on the very day it was supposed to happen? They found that while only about 5.6 percent of all scheduled surgeries were canceled on the day of the procedure, the rate was not spread evenly. Children living in the most socially vulnerable neighborhoods faced a cancellation rate of 9.2 percent, more than double the rate of 4.0 percent seen for children in the least vulnerable neighborhoods.

When the researchers dug deeper into the data, they found that the risk was not just about the neighborhood. Even after adjusting for the social conditions of the area where a family lived, being Black remained a strong, independent predictor of a same-day cancellation. Black children made up 19 percent of the total group of patients in the study, but they accounted for 36 percent of the children whose surgeries were canceled on the day of the procedure. This pattern held true across different surgical specialties and remained consistent even after the peak of the pandemic, suggesting that the issue is not a temporary glitch but a persistent feature of the system. The study also looked at why these cancellations happened. In the most vulnerable neighborhoods, the reasons shifted away from clinical issues, like a child being sick, and moved toward logistical and behavioral factors. The proportion of cancellations attributed to families not showing up for their appointment rose from 2.7 percent in the least vulnerable areas to 14.1 percent in the most vulnerable areas. Similarly, cancellations due to families changing their minds or failing to follow pre-surgery instructions increased significantly with neighborhood vulnerability.

The researchers used a specific tool called the Social Vulnerability Index to break down neighborhood disadvantage into four categories: economic status, household characteristics, racial and ethnic minority status, and housing and transportation. They discovered that while all these factors were linked to cancellations in a general sense, the economic status of a neighborhood was the primary driver when the factors were analyzed together. This suggests that the root of the problem lies more in financial and resource constraints than in housing or transportation barriers alone. However, the fact that race remained a significant factor even when the neighborhood's economic status was taken into account points to a larger, structural reality. It implies that the challenges faced by Black families extend beyond the immediate statistics of their zip code, reflecting historical and systemic inequalities that affect their ability to navigate complex medical schedules.

The study also noted that the pandemic played a role in the early years of the data, with COVID-19 infections causing a large number of cancellations in 2020, 2021, and 2022. Yet, as the pandemic receded and those infection-related cancellations dropped to near zero, the gap between vulnerable and non-vulnerable neighborhoods did not disappear. The disparity persisted, indicating that the underlying social and racial inequities were not merely a result of the pandemic's chaos but were embedded in the routine functioning of surgical care. The authors concluded that these findings highlight a need for new approaches. Since the data shows that the risk is highest for specific groups and is often driven by issues like missing appointments or failing to prepare, they suggest that hospitals could use neighborhood vulnerability data to identify high-risk families before the day of surgery. By offering targeted support, such as better communication or navigation help, hospitals might be able to prevent these cancellations, though the study itself did not test whether such interventions would work. The work serves as a clear map of where the problem lies, showing that for many children, the path to surgery is blocked not by medical necessity, but by the social conditions of their lives.
