Abstract
Objective To describe barriers to the successful use of the 1997 National Heart, Lung, and Blood Institute (NHLBI) asthma guidelines. Methods We conducted 3 focus groups to understand barriers to the use of 4 recommendations within the NHLBI guidelines (prescription of inhaled corticosteroids, recommendation of daily peak flowmeter use, smoking cessation screening and counseling, and allergen exposure counseling). Participants Twenty-one pediatricians and 1 nurse practitioner, who each followed an average of 47 patients with asthma, participated. Six participants (27%) had a faculty or adjunct appointment at a medical school. Nineteen (90%) of the 21 pediatricians were board certified. Results We identified 171 comments about barriers to adherence. Type of recommendation and physician year of graduation from medical school were related to which barrier was prominent. For corticosteroid prescription, senior physicians mentioned lack of agreement, whereas younger physicians described lack of confidence in dosing or recognizing contraindications. For peak flowmeter use, senior physicians emphasized lack of training. Only senior physicians described the inertia of previous practice as a barrier. All groups mentioned time limitations. Conclusions Efforts to improve adherence to asthma guidelines should consider the range of barriers that pediatricians face, such as lack of awareness, familiarity, or agreement, and external barriers owing to environmental, guideline, or patient factors. In addition, this study documents barriers not previously considered, such as lack of self-efficacy, lack of outcome expectancy, and inertia of previous practice, that prevent adherence. Because type of recommendation and physician demographics are related to which barriers are prominent, interventions to improve NHLBI guideline adherence should be tailored to these factors.
