Results of a program to reduce admissions for adult asthma

To determine the effect of an outpatient program designed to reduce readmissions for asthma exacerbations among adults with asthma.

Randomized patient selection with crossover.

Bellevue Hospital, New York City, New York.

We identified 104 adult asthmatics who had previously required multiple hospitalizations for asthma attacks. Forty-seven patients were randomly assigned to an intensive outpatient treatment clinic and 57 patients continued to receive their previous outpatient care. Nineteen patients from this latter group were then crossed to the intensive outpatient therapy clinic.

Attenders of the intensive outpatient treatment program were treated with a vigorous medical regimen and educational program. Emphasis was placed on teaching patients aggressive self-management strategies in case of marked asthma exacerbation.

The main measurement used to determine efficacy of the study program was readmission rate and hospital days used. Prospective comparison of treated compared with untreated patients indicated that program enrollment resulted in a threefold reduction in readmission rate and a twofold reduction in hospital day use rate (P less than 0.004 and P less than 0.02, respectively). Using retrospective data with patients serving as their own controls, we found a threefold reduction in readmission rate and in hospital day use (P less than 0.003) during a 32-month follow-up period. A similar magnitude of reduction in hospital utilization was found when patients were crossed over to the intensive treatment group (P less than 0.004).

By using a vigorous medical regimen and intensive educational program, we were able to decrease hospital use among a group of adult asthmatics who had previously required repeated readmissions for acute asthma exacerbations.
