When an older adult arrives at a crowded emergency department, clinicians often have only minutes to decide who among them is quietly at risk of deterioration. A recent narrative review published in Frontiers in Medicine surveyed the short geriatric screening tools designed for exactly this moment, proposing a tiered, two-step strategy: a rapid screen first, followed by a more detailed multidomain assessment for those flagged as vulnerable. Now, in a commentary on that review, researchers from Hospital Sírio-Libanês and the University of São Paulo argue that one tool was left out of the picture, and that its omission matters.
The commentary, authored by Pedro K. Curiati, Thiago J. Avelino-Silva and Márlon J. R. Aliberti, takes no issue with the review’s overall framework. The reviewers, Cešljarac and colleagues, explicitly stated that clinical relevance and clarity were prioritized over exhaustive coverage. The commentary writers accept that pragmatic choice but contend that brevity carried a cost: the exclusion of composite instruments, most notably the PRO-AGE score, developed in Brazil in 2020. In their view, this tool is not an obscure addition but a clinically relevant option that fits squarely within the two-step approach the review endorses.
PRO-AGE is an acronym that maps directly onto its content. The score integrates six geriatric domains: Physical impairment, Recent hospitalization, Older age, Acute mental alteration, Getting thinner, and Exhaustion. It ranges from 0 to 8 points, blends brief patient- or proxy-reported information with clinical data already routinely available at the bedside, and can typically be calculated in less than two minutes. That speed is the point. Emergency departments operate under strict time constraints, and any screening instrument that demands lengthy assessment is unlikely to survive contact with a busy clinical workflow.
The evidence base behind the score has grown substantially since its derivation. According to the commentary, validation has progressed from the original single-center study to multicenter investigations across emergency care settings, collectively encompassing more than 7,800 older adults. Across these studies, the authors report, PRO-AGE consistently showed good discrimination for clinically meaningful outcomes, including hospital admission, prolonged length of stay, short-term mortality, and post-discharge functional decline.
The numbers in the accompanying summary table illustrate that performance. In the original derivation study published in Annals of Emergency Medicine, which enrolled 5,025 patients aged 70 and older in a Brazilian geriatric emergency department, the score achieved an area under the receiver operating characteristic curve of 0.74 for hospital admission, 0.79 for prolonged stay beyond seven days, and 0.89 for in-hospital death. It also outperformed two established screening instruments, ISAR and FRAIL, with a net reclassification improvement ranging from 16 to 46 percent.
Further validation followed in a different clinical context. A study in Age and Ageing examined 1,428 patients aged 50 and older admitted to COVID-19 wards at a tertiary university hospital in Brazil. There, PRO-AGE achieved an AUC of 0.70 for 60-day mortality, compared with 0.62 for ISAR, and improved mortality risk stratification when incorporated into illness-acuity measures such as the National Early Warning Score. A third study, a multicenter federated analysis published in the Journal of the American Geriatrics Society, followed 1,390 emergency department admissions aged 65 and older in the United States and Brazil. Patients in the upper PRO-AGE group strongly predicted 90-day mortality, with hazard ratios of 11.76 in the US cohort and 12.29 in the Brazilian cohort, and new disability in activities of daily living, with hazard ratios of 2.08 and 1.70 respectively.
Head-to-head comparisons form a recurring theme in this evidence. The commentary emphasizes that PRO-AGE demonstrated incremental prognostic value over ISAR and FRAIL across investigations, suggesting that its multidomain construction captures risk information that narrower screens miss. Rather than replacing comprehensive geriatric assessment, the authors position the score as an enhancer of the first step: by flagging specific deficits such as mobility or cognitive problems during the rapid initial screen, it may allow clinicians to target and tailor the second, more detailed evaluation intelligently.
The authors are candid about the tool’s limitations, and their honesty is instructive. PRO-AGE relies on patient or proxy recall for items such as unintentional weight loss and acute functional decline, information that can be difficult to obtain in an overcrowded emergency department when no reliable informant is present. Moreover, because the score deliberately prioritizes sensitivity for detecting vulnerability, its specificity is only moderate. The commentary argues this is not a flaw but a design feature: PRO-AGE is best used precisely as the review recommends, as an initial trigger for further assessment rather than a definitive diagnostic instrument. A high score should prompt focused evaluation of cognition, mobility, nutrition, medication use, and patient priorities, followed by interventions matched to the deficits identified.
Geography remains the most significant caveat. The current validation evidence is concentrated primarily in Brazil, supplemented by a smaller multicenter cohort in the United States. Whether the score performs comparably in European or other health systems, with different patient populations, care pathways, and baseline risks, is not yet established. External validation studies are currently underway in the European Union and the United Kingdom, and their results will be important for judging the tool’s broader international applicability beyond the Americas.
The broader argument of the commentary extends beyond a single instrument. As emergency departments increasingly adopt age-friendly models of care, the demand is growing for screening tools that combine efficiency with clinically meaningful multidomain information. The review’s own conclusion, endorsed by the commentary writers, is that no single screening instrument simultaneously achieves high sensitivity and specificity, and that effectiveness depends on integrating screening into routine workflows linked to actionable interventions. Within that evolving landscape, the commentary contends, including PRO-AGE alongside established instruments would give readers a more complete overview of contemporary strategies for rapid geriatric risk stratification in acute care, and ultimately help clinicians identify, within minutes, the older adults who most need a closer look.
