This study concerns an analysis of the feasibility, validity, and repeatability of telephone interviews for the collection of data concerning health-related quality of life in asthma and patient reports of their use of asthma therapy. A computer-assisted hierarchical interview algorithm was developed that allowed rapid and precise recording of all aspects of asthma medication including drug, dose, and delivery system. This questionnaire was used together with the Symptoms and Impacts components of the St. George's Respiratory Questionnaire (SGRQ) in one face-to-face and then in three computer-assisted telephone interviews (CATIs) that took place 1, 3, and 13 weeks later. One hundred patients with asthma who had received inhaled steroids within the previous year were identified from general practice records. The intraclass correlation between the face-to-face interview and the first CATI for the SGRQ scores and the daily dose of inhaled steroid was approximately 0.8. For daily bronchodilator use, this value was 0.56. The intraclass correlation obtained between two CATIs 3 months apart was a little lower: SGRQ scores, 0.78; inhaled steroid dose, 0.67; bronchodilator use, 0.58. Telephone interviews can provide repeatable and efficient measurements of health and patient-reported drug use in asthma.
本研究旨在分析通过电话访谈收集哮喘患者健康相关生活质量数据以及患者哮喘治疗用药报告的可行性、有效性和可重复性。开发了一种计算机辅助分层访谈算法，可快速、精确记录哮喘药物治疗的各个方面，包括药物、剂量和给药系统。该问卷与圣乔治呼吸问卷（SGRQ）的症状和影响部分一起，先进行了一次面对面访谈，然后在1周、3周和13周后进行了三次计算机辅助电话访谈（CATI）。从全科医疗记录中确定了100名在过去一年中接受过吸入性类固醇治疗的哮喘患者。面对面访谈与第一次CATI之间，SGRQ评分和吸入性类固醇日剂量的组内相关系数约为0.8。对于每日使用支气管扩张剂的情况，该值为0.56。相隔3个月的两次CATI之间获得的组内相关系数略低：SGRQ评分，0.78；吸入性类固醇剂量，0.67；支气管扩张剂使用情况，0.58。电话访谈可为哮喘患者的健康状况及患者报告的药物使用情况提供可重复且有效的测量。
