The purpose of this study was to determine the relationship between patients' perception of asthma control and generic and asthma-specific quality of life (QOL) post-completion of a behavior modification-based adult asthma education program. A secondary objective was to examine associations between changes in perceived control of asthma and generic and asthma-specific QOL. Outcome measures were collected via an asthma management questionnaire (AMQ), generic (SF-36) and asthma-specific (AQLQ) QOL questionnaires, and a perceived control of asthma questionnaire (PCAQ). The cohort (n = 55) consisted of predominately female (75%), married (56%), middle income (46%) patients with severe asthma (65%) who had completed a university or college education (20%) and were working full-time (42%). The mean age was 45.2 (SD = 17.5) years. Perceived control of asthma and generic and asthma-specific quality of life significantly improved after completing the behavior modification-based adult asthma education program. Significant associations were found between perceived control of asthma (PCAQ) and both generic (SF-36) and asthma-specific QOL (AQLQ). Baseline PCAQ was related to all four domains and the total score of the AQLQ and 5 of the 8 domains of the SF-36. PCAQ was related to 3 of the 4 AQLQ domains at 3 months and total AQLQ score at both 1 and 3 months post-education. PCAQ was related to all 8 domains of the SF-36 at 1 month; and 4 of 8 domains at 3 months. Change in PCAQ (deltaPCAQ) was related to change in symptom score, emotional functioning, and total AQLQ score from baseline to 1 month and change in symptom score from baseline to 3 months. In conclusion, perceived control of asthma in patients participating in a behavior modification-based asthma education program was related to generic and disease-specific QOL. An improvement in PCAQ was associated with improved QOL following asthma education. Using the PCAQ as part of an asthma educational needs assessment may be a quick, simple way to identify and target education towards asthma patients with low perceived control.

This e-version of the MiniAQLQ is valid and was preferred by most participants despite taking slightly longer to complete. Generalizabilty may be limited in younger (12-17) and older (>65) adults.

Objective: We sought to determine whether a standardized emergency department (ED) asthma care pathway (ACP) for adults would be accepted by ED staff, improve adherence to Canadian ED asthma management guidelines and improve patient outcomes. Methods: Ten Ontario hospital EDs (5 intervention, 5 control) participated in a 5-month pre-post intervention study. Emergency department management, admissions, repeat ED visits and ED length of stay were compared between sites and by ACP use versus nonuse at intervention sites. Results: The ACP was used in 101 of 383 visits (26.4%) at 5 intervention sites. Use of the ACP varied significantly between sites, ranging from 6% to 60% (p < 0.001). When compared with control sites, there were significant increases in the use of metered dose inhalers (MDIs), inhaled steroids, referrals, documentation of teaching, patient recollection of teaching (all with a p < 0.001) and oxygen (p = 0.001). Use of peak expiratory flow rate (PEFR) measurements decreased in both intervention and control sites. Increased PEFR documentation and systemic steroid use in the ED and on discharge were only found in patients who were on the ACP at intervention sites. Admissions increased from 3.9% to 9.4% at intervention sites in contrast to control sites, where they remained fairly stable (p = 0.016), but did not differ by ACP use. The length of stay for discharged patients increased by a mean of 16 minutes for ACP patients at intervention sites (p = 0.002). There were no statistically significant differences in repeat ED visits. Conclusion: Adoption of a standardized ED ACP for adults is highly variable. Despite modest uptake, which averaged 26%, beneficial changes in specific aspects of asthma care delivery were found, notably in referrals and recollection of teaching done during the ED visit, without a substantial increase in ED length of stay. These changes may lead to improvements in outcomes, such as reduced relapse rates, which this study was not designed or powered to detect. Provincial and national implementation strategies that address barriers to clinical pathway adoption are warranted and have the potential to improve adherence to guidelines and outcomes for asthma patients. RÉSUMÉObjectif : Nous avons voulu vérifier si un plan clinique standardisé pour le traitement de l'asthme chez l'adulte serait accepté par le personnel des urgences et s'il allait promouvoir l'observance des lignes directrices canadiennes pour la prise en charge de l'asthme aux urgences et améliorer le pronostic des patients. Méthode : Dix services d'urgence d'hôpitaux en Ontario (5 appliquant l'intervention et 5 témoins) ont participé à cette étude pré-et post-intervention d'une durée de 5 mois. Nous avons comparé la prise en charge, les admissions, les visites multiples et la durée du séjour aux urgences entre les différents services, selon qu'ils appliquaient ou non le plan clinique. Résultats : Cinq services d'urgence assignés au groupe appliquant l'intervention ont effectivement utilisé le plan clinique lors de 101 c...
