Five-Item Frailty Index Predicts ICU Care and Mortality in Geriatric Hip Fractures, Suggests Study

Geriatric hip fractures inflict substantial morbidity, mortality, and loss of functional independence, positioning frailty as a crucial determinant of surgical outcomes; yet, despite the clinical utility of the five-item Modified Frailty Index (5-mFI), its prognostic role within low- to middle-income countries (LMICs) remains insufficiently characterized. To address this clinical knowledge gap, Dr. Deepanjan Das and co-authors from the Department of Orthopaedics at a tertiary teaching hospital in India evaluated whether the 5-mFI effectively prognosticates perioperative acuity, functional recovery, and survival outcomes in older surgical candidates.

Therefore, the retrospective study of 138 elderly hip fracture surgical patients at an Indian tertiary hospital evaluated perioperative acuity, Intensive Care Unit (ICU) needs, and 1-year survival across 5-item Modified Frailty Index (5-mFI) tiers. Excluding incomplete records, researchers also assessed American Society of Anesthesiologists (ASA) physical status, 12-month functional recovery using the Harris Hip Score (HHS), and pain levels via the Visual Analogue Scale (VAS).

Key clinical findings from the study include:

• Heightened Perioperative Acuity: Investigators observed that higher 5-mFI scores significantly correlated with increased ICU admission rates (Spearman's ρ = 0.45, p < 0.001) and prolonged intensive care stays (ρ = 0.60, p < 0.001).
• Elevated Anesthetic Risk: The authors demonstrated a strong positive correlation between advancing frailty tiers and higher preoperative ASA grades (ρ = 0.54, p < 0.001).
• Reduced Long-Term Survival: Researchers recorded an overall 1-year mortality rate of 16.7%, noting significantly reduced 12-month survival among patients with high frailty (5-mFI ≥ 2) compared to low frailty cohorts (5-mFI 0–1) (log-rank p = 0.006).
• Unchanged Functional Recovery: Trial data revealed that baseline frailty status exhibited no significant association with 12-month postoperative joint function (HHS) or pain scores (VAS).

The results suggest that the 5-mFI is a practical and clinically relevant tool to stratify perioperative risk in geriatric hip fracture patients within LMICs, strongly predicting intensive care demands and 1-year mortality (16.7%). However, baseline frailty scores did not dictate long-term functional recovery or persistent joint pain at 12 months postoperatively.

Thus, the study concludes that clinicians can readily incorporate this straightforward 5-point assessment into routine preoperative workflows to identify vulnerable geriatric patients requiring vigilant perioperative monitoring and critical care support.

Although the single-center retrospective design represents a modest study constraint, conducting larger prospective multicenter trials will further validate the prognostic utility of frailty scoring across diverse surgical cohorts.
