Impact of a standardized emergency department asthma care pathway on health services utilization

Résumé fourni par la source

BACKGROUND: An evidence-based standardized ED asthma care pathway (EDACP) was developed and implemented in Ontario, Canada. OBJECTIVE: To determine the impact of EDACP implementation and access to ED asthma management resources and specialists on return ED visits. METHODS: All 173 Ontario hospitals were surveyed regarding their access to community and ED asthma specialists and ED asthma management resources, including EDACP implementation date and status as of August 2017. Survey data were linked to provincial health administrative data to quantify acute health services utilization. A Poisson regression interrupted time series analysis was conducted. RESULTS: Of the 123 hospitals responding to the survey, 44 (35.8%) had approved the EDACP. Data were analyzed for the 5 years preceding (30,028 asthma visits) and 17 months following (7,916 asthma visits) implementation, with a 3-month implementation black-out period. After controlling for auto-regressive factors, EDACP implementation was associated with a 2% reduction in the absolute rate of return ED visits within 72 h (p = 0.0124), and within 7 days (p = 0.0295) at teaching hospitals. The same effect was not seen at community hospitals. Peak expiratory flow testing (available at 77% of sites) and spirometry (available at 45% of sites) were associated with 34% (p = 0.0071) and 23% (p = 0.028) reductions in the odds of return ED visits within 72 h, respectively. CONCLUSION: The positive results from this large-scale effort to implement an evidence-based knowledge translation initiative in diverse settings, suggests there is merit in continuing to invest time and resources to overcome barriers to adoption and implementation of this EDACP.
