Doctor Patient Descrepancies In Asthma Care

According to the Asthma In America survey:

• 70% of doctors report regular spirometry use to measure patient airflow on an ongoing basis, but only 35% of patients report having spirometry in the past year.
• While more than 9 out of 10 of doctors stressed the importance of anti-inflammatory drugs for the treatment of asthma, less than 2 out of 10 of asthma patients reported anti-inflammatory medication use in the prior four weeks.
• While more than 8 out of 10 of doctors report prescribing peak-flow meters to their asthma patients, only 6 out of 10 patients have ever heard of a peak flow meter. However only 3 out of 10 asthma patients actually have a peak flow meter and only 1 in 10 actually use it at least once a week.
• While 7 out of 10 physicians report developing asthma action plans for their patients, less than 3 out of 10 patients report receiving an asthma action plan from their asthma care providers.

As a practicing physician that sees both adults and kids with asthma, this is pretty disturbing to me. Why do you think there is such a discrepancy between what physicians and their patients report? What do you think can be done to improve these numbers? What would you suggest?
