简要总结
The overall goal of this randomized, controlled study is to compare a model written treatment plan with the usual care that is provided by a group of adult and pediatric pulmonologists and allergists in their practice settings. The written treatment plan is a form that allows a treatment regimen that is consistent with National Heart, Lung, and Blood Institute (NHLBI) guidelines to be conveyed to patients. Barriers to the use of written plans will be identified to better understand why some patients and physicians use written treatment plans more frequently and effectively than others. An additional goal is to assess how patients from different racial/ethnic backgrounds utilize treatments plans. Because asthma disproportionately affects African American and Latino patients, another goal of this study is to better understand if there are fundamental differences in the way patients from racial/ethnic minority groups self-manage asthma in comparison to their white counterparts. The study will also try to determine if differences exist in the way physicians care for minority patients. If there are differences, it is important to determine if the disparities can be overcome with the use of a written treatment plan form.
详细描述
BACKGROUND:
Effective self-management of asthma requires that patients, or their caregivers, recognize the early symptoms of an exacerbation and initiate appropriate interventions aimed at preventing the progression of symptoms. Most asthma clinical guidelines suggest that the incorporation of a written self-management plan is essential. Patients must possess, understand, and follow a written plan if they are to respond appropriately to changes in asthma status. Nevertheless, there are no controlled studies examining the efficacy of the written plan itself. Furthermore, even if written plans are an essential and effective component of successful self-management, the data suggest that few patients receive these plans. If patients and physicians are to increase their use of written plans, the barriers to the use of these plans need further investigation.
DESIGN NARRATIVE:
The three primary outcome measures of this study are as follows: 1) reduction in asthma symptom frequency; 2) reduction in urgent, unscheduled, and emergency visits for asthma; and 3) improved quality of life. These outcomes will be measured over a 12-month period.
The following four secondary outcome measures will also be examined: 1) hospitalizations due to asthma; 2) days with activity restriction; 3) the proportion of patients in the intervention group who are given the model written plan form during the initial visit; and 4) the proportion of patients in the intervention group who have the model treatment plan at the end of the follow-up period. These outcomes will be measured over a 12-month period.

结局指标
主要结局
Reduction in asthma symptom frequency
时间窗: Measured at 3 month intervals for 12 months
Using a 2-week recall period, asthma symptom frequency was measured in 3 ways: (a) the average number of days with asthma symptoms; (b) the average number of nights with symptoms; and (c) the average number of days the participant used a short-acting bronchodilator.
Reduction in urgent, unscheduled, and emergency visits for asthma
时间窗: Measured at 3 month intervals for 12 months
Emergency, urgent, and unscheduled visits for asthma were combined into a single measure and assessed using a 3-month recall.
Improved quality of life
时间窗: Measured at 6 and 12 months
Asthma QOL, using the Juniper Mini Asthma QOL Scale (MiniAQLQ) for adult participants and the Juniper Pediatric Asthma Caregivers QOL Questionnaire (PACQLQ) for parents, was assessed at 6 and 12-months follow-up.
次要结局
- Proportion of participants in the intervention group who are given the written asthma action plan form during the initial visit(Measured at the exit interview after the initial visit with the specialist physician)
- Hospitalizations due to asthma(Measured at 3 month intervals for 12 months)
- Proportion of patients in the intervention group who have the model treatment plan at the end of the follow-up period(Measured at 12 month interview)
- Days with activity restriction(Measured at 3 month intervals for 12 months)
