    Ojective:

    To achieve our goal of excellent emergency cardiac care, our institution embarked on a Lean process improvement initiative. We sought to examine and quantify the outcome of this project on the care of suspected acute coronary syndrome (ACS) patients in our emergency department (ED).

    Methods:

    Front-line ED staff participated in several rapid improvement events, using Lean principles and techniques such as waste elimination, supply chain streamlining, and standard work to increase the value of the early care provided to patients with suspected ACS. A chart review was also conducted. To evaluate our success, proportions of care milestones (first electrocardiogram [ECG], ECG interpretation, physician assessment, and acetylsalicylic acid [ASA] administration) meeting target times were chosen as outcome metrics in this before-and-after study.

    Results:

    The proportion of cases with 12-lead ECGs completed within 10 minutes of patient triage increased by 37.4% (p < 0.0001). The proportion of cases with physician assessment initiated within 60 minutes increased by 12.1% (p = 0.0251). Times to ECG, physician assessment, and ASA administration also continued to improve significantly over time (p values < 0.0001). Post-Lean, the median time from ECG performance to physician interpretation was 3 minutes. All of these improvements were achieved using existing staff and resources.

    Conclusions:

    The application of Lean principles can significantly improve attainment of early diagnostic and therapeutic milestones of emergency cardiac care in the ED.

    Objective: Some low-acuity emergency department (ED) presentations are considered convenience visits and potentially avoidable with improved access to primary care services. This study assessed the frequency and determinants of patients' efforts to access alternative care before ED presentation.

    Methods: Patients aged 17 years and older were randomly selected from 2 urban ED sites in Edmonton. Survey data were collected on use and characteristics of alternative care before the ED visit. Information was also collected on patient demographics and factors influencing their perception of whether the ED was the best care option.

    Results: Of the 1389 patients approached, 905 (65%) completed the survey and data from 894 participants were analyzed. Sixty-one percent reported that they sought alternative care before visiting the ED. Eighty-nine of the patients who attempted alternative access before the ED visit felt that the ED was their best care option. Results of the multivariate logistic regression analysis showed that injury presentation, living arrangements, smoking status and whether or not patients had a family practitioner were predictors for seeking alternative care before visiting the ED.

    Conclusion: Most ambulatory patients attempt to look for other sources of care before presenting to the ED. Despite this attempted access to alternative care, while patients wait for ED care, they perceive that the ED is their best care option at that point in time.
