Sarah Remer, a general surgery resident at Loyola University Medical Center in Illinois, noticed something troubling: some hospitals were catching nearly all cases of post-surgery delirium in older patients, while others were missing half of them entirely. That gap—94.3% screening at accredited hospitals versus just 52.5% at non-accredited ones—reveals a quiet crisis hiding in plain sight across American hospitals.
Delirium after surgery is insidious because it often wears a mask. Rather than appearing as agitation or obvious confusion, it frequently manifests as withdrawal and lethargy—what Remer calls "the quiet form." A patient becomes drowsy and withdrawn, and clinicians mistake it for ordinary fatigue. Without routine screening, these cases slip through undetected, robbing patients of the early intervention that could change their recovery.
The American College of Surgeons' Geriatric Surgery Verification Program was created precisely to prevent this. Hospitals that meet its standards screen older surgical patients systematically using validated tools that take only minutes at the bedside—looking for signs like inattention, disorganized thinking, or altered consciousness. A new study published in the Journal of the American College of Surgeons reveals how effectively this approach works.
The data is striking. GSV-accredited hospitals screened 94.3% of older surgical patients, while non-accredited hospitals screened only 52.5%. Yet when both groups did screen, they found similar rates of positive delirium: 11.3% versus 12.5%. This suggests that non-accredited hospitals weren't finding fewer cases of delirium—they were simply missing them. Hospitals with the lowest screening rates had surprisingly high positivity rates among the few patients they did test, hinting at how many cases were slipping away undetected.
The real benefit emerged when researchers looked at patients who were screened. Those treated at GSV hospitals had shorter hospital stays and fewer prolonged hospitalizations. For patients who developed delirium despite screening, outcomes leveled out—but early detection had already bought them precious time for intervention and recovery. This suggests the greatest value lies not in screening alone, but in the standardized, multidisciplinary care processes that accredited hospitals use to prevent delirium from taking root in the first place.
Delirium carries a steep cost. It's associated with longer stays, worse outcomes, and higher healthcare expenses. Yet it's also largely preventable with attention to the basics: ensuring patients have their glasses and hearing aids back promptly, keeping clocks and calendars visible, maintaining natural light cycles, and encouraging daytime engagement.
Family members are crucial partners in this prevention. Delirium looks different from a person's baseline behavior, making loved ones often the first to notice something wrong. A daughter might catch the subtle change in a parent's thinking that a busy clinician misses. These family observations can alert the clinical team to sudden shifts and help patients stay oriented and engaged.
Remer's work illuminates a path forward: standardized screening, multidisciplinary care, and family involvement working together. The gap between 94% and 52% is not inevitable. It's a measure of how much difference intentional systems make—and how many older adults could benefit if more hospitals committed to catching delirium before it took hold.
