National Heart, Lung, and Blood Institute Guidelines and Asthma Management Practices Among Inner-City Pediatric Primary Care Providers

Background and objective

Most surveys of pediatric outpatient asthma management obtain information from parents and caregivers. Studies based on surveys of primary health-care providers are sparse. Suboptimal outpatient management may play a role in the high hospitalization rates among inner-city asthmatic children. Asthma management practices were compared between hospital-based and community-based primary care providers (PCPs). Adherence to National Heart, Lung, and Blood Institute (NHLBI) guidelines was evaluated, along with practices not clearly defined in the guidelines such as use of oral cough medicines and albuterol suspension.

Design/methods

An 8-point questionnaire was administered to 48 community-based and 32 hospital-based PCPs practicing in inner-city neighborhoods. The questionnaire addressed three “positive” practices (classification of asthma severity, use of asthma action plan, and use of a spacer) and three “negative” practices (use of cough syrup, use of albuterol suspension, and preferential use of leukotriene modifiers instead of inhaled corticosteroids as the first line of preventive therapy). Response options were as follows: never, rarely, sometimes, and always, scored from 0 to 3. The two physician groups were compared on score means for the positive and negative practices using a t test with statistical significance set at p < 0.05.

Results

Overall, the rate of adherence to the positive practices was high, with no significant difference between the two groups. Negative practices, while present in both the groups, were reported significantly more often by the community-based group, particularly the use of cough suppressants and albuterol suspension.

Conclusions

Greater emphasis is needed to increase the awareness among PCPs of the NHLBI guideline recommendations, as suboptimal outpatient asthma management may contribute to the disproportionately higher hospitalization rates among inner-city asthmatic children. Clarification on the use of potentially harmful medications and those of doubtful value need to be incorporated in the guidelines. The extent to which these negative practices contribute to the elevated pediatric hospitalization rates warrants further investigation.
