  Purpose

The purpose of the study is to evaluate whether the Emergency Department (ED) Asthma Care Project (ACP) leads to improved asthma care delivery and patient outcomes in the ED setting.

Hypothesis: Implementation of a multi-disciplinary asthma strategy/clinical pathway for the treatment of asthma in the ED, based upon the 1999 Canadian Asthma Consensus Guidelines (and subsequent updates), will increase adherence with published management guidelines in the ED setting, reduce variations in the emergency management of acute asthma, increase utilization of specialized asthma services and improve outcomes for patients following ED visits.

Methods:

This observational, pre- post-intervention study will compare a stratified sample of 10 Ontario hospital EDs (5 intervention and 5 control sites). Chart abstractions will be performed on all adult visits for acute asthma over a 3 month period before and after implementation of the Ontario Hospital Associations (OHA)'s (now Ontario Lung Association's (OLA's) ED Asthma Care Map. Patient and provider surveys and provider focus group post intervention will also be conducted. Primary outcome measures are hospitalizations and repeat ED visit rates. Secondary outcome measures include: length of stay in ED, self-reported adherence with referral to specialized asthma services made during index ED visit, self-reported asthma control, and use of self-management strategies (including use of action plan), use of asthma management strategies promoted by the care map (such as use of objective measure of airflow rates, use of steroids, education, referral to specialized asthma services on discharge). Ease of implementation and barriers to implementation will also be evaluated.

Further study details as provided by Dr. Diane Lougheed, Queen's University:

Primary Outcome Measures:
  • % of ED visitors admitted to hospital for asthma [ Time Frame: At the end of the index ED visit (this is a dichotomous outcome. It is not possible to specify a "time frame"). ]
    The patient is either admitted or not at the end of the ED visit.

  • Repeat Emergency Department visit rate for asthma [ Time Frame: Within 24, 72h, 1 month ]

Secondary Outcome Measures:
  • Hospitalization length of stay [ Time Frame: From ED presentation to hospital discharge ]
    It is not possible to specify a 'time frame'; the length of stay is the outcome

  • Length of stay in ED [ Time Frame: From ED presentation to ED discharge ]
  • Self-reported adherence with referral to specialized asthma services made during index ED visit [ Time Frame: At folllowup questionnaire ]
  • Self-reported asthma control, and use of self-management strategies (including use of action plan) [ Time Frame: At followup questionnaire ]
  • Use of Asthma Management Strategies Promoted by the ED ACP: use of objective measure of airflow rates (PEFR or spirometry), and gas exchange (oxygen saturation, arterial blood gases) [ Time Frame: During index ED visit (between ED presentation and ED discharge). ]
    These are dichotomous outcomes describing actual care received during the ED visit.

  • ; types of asthma medications prescribed (bronchodilators, corticosteroids) in ED and upon discharge; route of medications prescribed (IV vs oral vs. inhaled steroids; MDI vs nebulized bronchodilators) [ Time Frame: During index ED visit (between presentation and discharge, including discharge orders and instructions). ]
    These are dichotomous outcomes describing actual care received during the ED visit.

  • ; documentation of assessment and teaching of device technique [ Time Frame: During index ED visit (between ED presentation and ED discharge) ]
    During index ED visit (between presentation and discharge, including discharge orders and instructions).

  • ; documentation of asthma action plan provision or revision [ Time Frame: During index ED visit (between ED presentation and ED discharge) ]
  • ; type of asthma education provided (e.g. environmental trigger avoidance, warning signs, medication use) [ Time Frame: During index ED visit (between ED presentation and ED discharge) ]
  • ; follow-up care recommendations or referrals (AEC, Asthma Clinic, Respirology Clinic, family physician) [ Time Frame: During index ED visit (between ED presentation and ED discharge) ]
  • Utilization of Specialized Asthma Services [ Time Frame: After discharge (within 12 months) ]
    Self-reported by patient on the followup questionnaire

  • ; referral rates (#/year) to local AECs and Asthma Clinics [ Time Frame: After discharge (within 12 months) ]
  • ; types of providers involved in emergency asthma care [ Time Frame: During index visit (between ED presentation and ED discharge) ]
  • Proportion of patients enrolled on the ED ACP (Overall, by patient age category and by physician specialty) [ Time Frame: During index visit (between ED presentation and ED discharge) ]
  • Differences in patient demographics, physician demographics, day of week, time of day between patients enrolled vs. not enrolled [ Time Frame: During index visit (between ED presentation and ED discharge) ]
  • Perceived utility of pathway (overall, by site, and by profession) [ Time Frame: At time of followup survey (wihtin 12 months) ]
