Objectives: To assess the knowledge of asthma among the caregivers of asthmatic children and to evaluate the outcomes of preliminary education.
Material and Method: The caregivers of asthmatic patients aged 2-15 years who attended the pediatric chest clinic of King Chulalongkorn Memorial Hospital from January to December 2003 were randomly recruited to answer the questionnaire about asthma prior to the educational discussion with the investigators or nurses. The questionnaire was done again 6 months later. The significant factors associated with adequate knowledge and change of knowledge of the caregivers were identified.
Results: Among the 79 study caregivers, forty-two (53.2%) had sufficient knowledge of asthma (score ≥34 out of 44). The average pre-test score was 33±3.6 (24-42). The duration of caring for their asthmatic child was the only significant factor associated with adequate knowledge (p<0.05). After the educational session, the post-test score was significantly improved (36.0±2.6; p<0.001).
Conclusion: Half of the caregivers of the asthmatic children had insufficient knowledge of asthma. Education about asthma is still needed to improve their knowledge.
