Chronic Illness and Multimorbidity Management
Core concepts
Multimorbidity means multiple coexisting chronic conditions, and management shifts from single-disease guidelines to goal-concordant, patient-prioritized care. Key concepts: the difference between disease-specific targets and individualized targets (e.g., relaxed glycemic goals in frail elders to avoid hypoglycemia), the concept of competing risks (treating one condition may worsen another), and time-to-benefit (preventive therapies with long horizons may not help those with limited life expectancy). Understand the geriatric syndromes-falls, incontinence, pressure injuries, delirium, frailty, and polypharmacy-which cross disease boundaries. Recognize frailty and sarcopenia as drivers of vulnerability. Care should emphasize function and quality of life, shared decision-making, and avoiding treatment burden.
Traps
Questions test whether you prioritize the patient's goals over rigid guideline targets. A classic trap is intensifying glucose control in a frail older adult, increasing hypoglycemia risk. Another is adding a medication to treat a side effect of another medication. Watch for distractors that apply strict single-disease targets to a multimorbid patient.
Rule of thumb
For frail older adults, relax targets when tight control risks hypoglycemia, falls, or treatment burden-and always ask which condition the patient prioritizes.
Worked example
A frail 84-year-old on insulin has an A1c of 6.8% and recurrent hypoglycemia. The best action is to loosen the glycemic target and reduce hypoglycemia risk, not to tighten control-her target should reflect frailty and safety, not a younger-adult standard.
