Don’t diagnose or manage asthma without spirometry.
|Rationale and Comments:||Clinicians often rely solely upon symptoms when diagnosing and managing asthma, but these symptoms may be misleading and be from alternate causes. Therefore, spirometry is essential to confirm the diagnosis in those patients who can perform this procedure. Recent guidelines highlight spirometry’s value in stratifying disease severity and monitoring control. History and physical exam alone may over- or underestimate asthma control. Beyond the increased costs of care, repercussions of misdiagnosing asthma include delaying a correct diagnosis and treatment.|
