Clinical Outcome of Asthmatic Pediatric Patients Following Spirometry Assessment of Pulmonary Function in Pediatric Asthma Clinic Chaophrayayommaraj Hospital.
Keywords:
asthmatic control rate, peak expiratory flow rate, spirometryAbstract
Objective: The purpose was to compare the control level of asthma and peak expiratory flow rate which was measured by peak flow meters, before with after using spirometry assessment of pulmonary function in pediatric asthmatic patients.
Methods: This was a retrospective quasi-experimental study of asthmatic pediatric patients aged 5 years and over who were treated in pediatric asthma clinic at Chaophrayayommaraj Hospital from October 1, 2016 to September 30, 2019. Data were collected and divided into two groups, i.e., before and after 6 months of pulmonary function measurement, thereafter; comparing asthmatic control level according to GINA guideline 2019 and peak expiratory flow rate was done. Data were analyzed by chi-square test or Fisher exact test and unpaired t test.
Results: After 6 months of pulmonary function assessment, the number of partly controlled and uncontrolled asthmatic patients was found to be lower but no statistical significance (11.4% vs 1.9% and 6.3% vs 0% respectively, p-value < .445). By peak flow meters, mean % PEFR was higher (74.9 + 15.14 vs 81.2 + 12.74, p-value < .001) and the number of patients with PEFR > 80% predicted increased (38.6% vs. 60.8%, p-value < .001) with statistical significance. The amount of usage of the long-acting beta-2 agonist + corticosteroid also increased in 107 patients (67.7%) from 49 patients (31%).
Conclusion: Spirometry assessment improved asthmatic control better than using of clinical symptom only. It helped to adjust controlling drug more properly.
