Sepsis in Frail Older Adults: Tailored Antimicrobial Stewardship and Individualized Care Approach

Frail older adults face an increased risk and severity of sepsis, which contributes to a notably high mortality rate. The management of sepsis in this population presents significant challenges, such as diagnostic complexity, a higher prevalence of multidrug-resistant pathogens, difficulties in achieving effective source control, and an increased risk of adverse events and toxicity associated with antibiotic therapy. In addition, accurate prognostic evaluation based on a comprehensive geriatric assessment is essential to determine the intensity of care required and to develop a personalized plan of care. Despite these considerations, frail older adults are still often underrepresented in randomized clinical trials and guidelines. In this narrative review, we discuss the main pillars of tailored antimicrobial stewardship in frail older adults. We propose a practical, stepwise approach to individualized care, delivered by a multidisciplinary team and based on a careful balance between treatment intensity and patients’ vulnerabilities, needs, and priorities.
