Help needed!

Hi all

Working out my PICO from today - can anyone help with my search terms?

My question is about the effectiveness of doubling dosage of steroid inhaler to prevent any exacerbation of asthma in a child less than 10 years old. It's how I enter 'double dosage' in MEDLINE - increased dosage maybe? (I will use MEDLINE's thesaurus and subject headings to help).

See you tomorrow.
