Cumulative Illness Rating Scale — Geriatric (CIRS-G)
14-organ-system comorbidity scoring tool designed for older adults. Each system scored 0 (no problem) to 4 (extremely severe). Total score 0–56. Used for risk stratification, research, and clinical decision-making in geriatric medicine.
Score interpretation
Higher totals mean a greater chronic illness burden; the CIRS-G has no validated total cut-offs. Systems rated 3 or 4 mark severe or uncontrolled problems.
→ Use the total with the count of level-3/4 systems: any level 3–4 system or a high total supports comprehensive geriatric assessment, medication review (STOPP/START) and multidisciplinary care planning.
Interpretation bands for the CIRS-G. Apply clinical judgement and local guidance.
