Panic-fear in asthma: requests for as-needed medications in relation to pulmonary function measurements.

Requests for as-needed medications and treatments (PRNs) by asthmatic patients scoring high, moderate, or low on the Asthma Symptom Checklist panic-fear category were studied for days when patients were matched at normal, intermediate, and subnormal levels of pulmonary function. Low panic-fear patients were the least likely to request PRNs regardless of the pulmonary function level. In contrast, high panic-fear patients often requested PRNs each level of pulmonary function. Only moderate panic-fear patients made progressively more PRN requests on days when pulmonary functions were lower. These observations and others concerning the adverse influence of extreme panic-feat coping styles upon the treatment of asthma were discussed.
