A woman in her fifties with fixed airflow obstruction and no smoking history is not a diagnostic puzzle in most of India — she is a biomass exposure that nobody wrote down. Years of cooking on wood, dung cake or coal in an unventilated kitchen produce chronic bronchitis and emphysema by a different route to tobacco, and the exposure is ongoing at the moment of the consultation.
So ask three things: what fuel is used for cooking, whether the kitchen has a window or a chimney, and how many hours a day are spent there. Then ask whether an LPG connection exists and, if it does, whether it is actually used — many households keep a cylinder for guests and cook on wood because refills cost money.
The reason this is worth the ninety seconds is that it is one of very few modifiable exposures left in an established COPD diagnosis. Inhalers treat the consequence; the kitchen is the cause, and it is still running.
- Ask the fuel, the ventilation and the hours — all three, not just the first
- Ask whether an existing LPG connection is actually being used for daily cooking
- Record biomass exposure in the diagnosis line, not only in the social history
- Extend the question to heating fuel where winters are cold
- Involve whoever controls household spending in the conversation; the barrier is usually cost, not knowledge
Why it matters
It is the only part of a COPD consultation that addresses the exposure rather than its consequences.
