Researchers conducted a pilot study to see if using Peak Expiratory Flow Rate (PEFR) values helped doctors treat patients with acute asthma in the emergency department. The study included 210 patients between the ages of 16 and 55 who did not have chronic obstructive pulmonary disease.
In one group, clinicians received PEFR values along with guideline-based recommendations. In the other group, clinicians were not shown these values and instead guided treatment based on symptoms alone. The results showed that both groups had similar success rates. Specifically, 72% of patients in both groups had none or mild asthma symptoms within 150 minutes.
There was also no significant difference in hospitalizations or the use of nebulized medications between the two groups. Because this was a small pilot study, the results are not enough to change standard medical practices yet. These findings suggest that adding PEFR values may not offer extra benefits for managing acute asthma in emergency settings.
