Most patients and parents view their asthma as serious, but their severity ratings differ from clinical measures. This highlights a need for better communication and shared goals in asthma management.

Area of Science:

  • Pulmonary Medicine
  • Epidemiology
  • Health Services Research

Background:

  • Limited epidemiological data exists on asthma severity distribution and patient-reported severity.
  • Understanding patient and parent perspectives on asthma severity is lacking.
  • Previous analyses have not focused on patient self-assessment of asthma severity.

Purpose of the Study:

  • To analyze patient-reported asthma severity using a large, nationally diverse sample.
  • To identify factors associated with self-reported asthma severity.
  • To compare patient perspectives with clinical definitions of asthma severity.

Main Methods:

  • Utilized data from the 1999 Medical Expenditure Panel Survey (household and event files).
  • Focused on a subgroup that completed the chronic disease portion of the survey.

  • Analyzed patient-reported asthma severity, healthcare utilization, medication usage, and personal characteristics.
  • Main Results:

    • 63% of adults and 65% of children reported their asthma as very or somewhat serious.
    • More severe self-reported asthma correlated with increased missed work/school days and lower health status.
    • Clinical criteria (NAEPP) explained less than 10% of the variation in self-reported asthma severity.

    Conclusions:

    • Patient and parent metrics for asthma severity differ from those used by clinicians.
    • A need exists for a more universally understood asthma severity measure.
    • Improved communication and shared therapeutic goals between patients and clinicians are essential.
