As the World Ages Faster Than Projected, a New Casebook Rethinks Geriatric Care Case by Case
In August 2026, the U.S. Census Bureau published An Aging World: 2025 (report P95-26-1), its first update to this flagship global demographic study since 2015 — and the headline finding is blunt: the world's population is aging faster than demographers envisioned just a decade ago. 77 countries now have 14% or more of their population at older ages, driven by a combination of falling death rates and falling fertility, and for the first time the Bureau extended its projections out to 2060 rather than 2050. Health systems built around a younger population pyramid are running out of runway.
Care of the Older Adult: A Clinical Casebook (Ronald M. Caplan, ed., Springer Cham, August 2026) answers a very practical version of that problem: how does a clinician actually make decisions for this patient population, case by case? Across 40 chapters, it departs from the usual disease-by-disease textbook structure and instead works the way real consults do — starting from a presenting scenario (a fall, delirium, a medication reaction in a frail patient) and walking through diagnosis, management, and prevention from there.
Three concrete uses for this casebook: ward and consult teams can pull individual chapters as quick-reference protocols for recurring scenarios such as falls, delirium, or perioperative risk in frail patients; residency and fellowship programs can assign cases directly as the basis for problem-based learning sessions; and primary care practices can use the frailty and polypharmacy-adjacent chapters to structure complex-patient visits that otherwise run long and unstructured.
For academic medical libraries, the timing matters as much as the content: this is a 2026, case-based companion to the standard geriatric medicine references, arriving in the same year the Census Bureau confirmed that population aging is outpacing prior projections almost everywhere data is collected. It is a natural addition to collections supporting geriatrics, internal medicine, and primary care training.

Q&A
Why is geriatric clinical training getting more attention in 2026?
The U.S. Census Bureau's August 2026 report An Aging World: 2025 found that global population aging is accelerating faster than projected a decade ago, with 77 countries now at 14% or more of their population at older ages.
What makes this casebook different from a standard geriatrics textbook?
It is organized by clinical scenario rather than by disease, walking through 40 real-world cases the way a clinician would actually encounter and work through them.
Who is this book written for?
Primary care physicians, geriatricians, internal medicine clinicians, fellows, residents, nurses, and the academic medical libraries that support them.
What clinical areas does it cover?
Falls and frailty, cognitive decline including Alzheimer's and Parkinson's disease, delirium, cardiac and pulmonary disease, stroke, diabetes, malnutrition, perioperative care, chronic kidney disease, and more.
