Engaging patients and primary care providers in the design of novel opinion leader based interventions for acute asthma in the emergency department: a mixed methods study.

BACKGROUND: Multifaceted interventions driven by the needs of patients and providers can help move evidence into practice more rapidly. This study engaged both patients and primary care providers (PCPs) to help design novel opinion leader (OL)-based interventions for patients with acute asthma seen in emergency departments (EDs). METHODS: A mixed methods design was employed. In phase I, we invited convenience samples of patients with asthma presenting to the ED and PCPs to participate in a survey. Perceptions with respect to: a) an ideal OL-profile for asthma guidance; and b) content, style and delivery methods of OL-based interventions in acute asthma directed from the ED were collected. In phase II, we conducted focus groups to further explore preferences and expectations for such interventions with attention to barriers and facilitators for implementation. RESULTS: Overall, 54 patients completed the survey; 39% preferred receiving guidance from a respirologist, 44% during their ED visit and 56% through individual discussions. In addition, 55% expressed interest in having PCP follow-up within a week of ED discharge. A respirologist was identified as the ideal OL-profile by 59% of the 39 responding PCPs. All expressed interest in receiving notification of their patients' ED presentation, most within a week and including diagnosis and ED/post ED-treatment. Personalized, guideline-based, recommendations were considered to be the ideal content by the majority; 39% requested this guidance through a pamphlet faxed to their offices. In the focus groups, patients and PCPs recognized the importance of health professional liaisons in transitions in care; patient anxiety and PCP time constraints were identified as potential barriers for ED-educational information uptake and proper post-ED follow-up, respectively. CONCLUSIONS: Engaging patients and PCPs yielded actionable information to tailor OL-based multifaceted interventions for acute asthma in the ED. We identified potential facilitators for the implementation of such interventions (e.g., patient interaction with alternative health care professionals who could facilitate transitions in asthma care between the ED and the primary care setting), and for the provision of post discharge self-management education (e.g., consideration of the first week of ED discharge as a practical time frame for this intervention). Prioritization of identified barriers (e.g., lack of PCP involvement) could be addressed by the identification of potential early adopters in practice environments (e.g., clinicians with special interest in asthma).

Effectiveness of Interventions to Decrease Emergency Department Visits by Adult Frequent Users: A Systematic Review.

OBJECTIVES: Frequent emergency department (ED) users are high-risk and high-resource-utilizing patients. This systematic review evaluates effectiveness of interventions targeting adult frequent ED users in reducing visit frequency and improving patient outcomes. METHODS: An a priori protocol was published in PROSPERO. Two independent reviewers screened, selected, rated quality, and extracted data. Third-party adjudication resolved disagreements. Rate ratios of post- versus pre-intervention ED visits were calculated. Data sources were from a comprehensive search that included seven databases and the gray literature. Eligibility criteria for selecting studies included experimental studies assessing the effect of interventions on frequent users' ED visits and patient-oriented outcomes. RESULTS: A total of 6,865 citations were identified and 31 studies included. Designs were noncontrolled (n = 21) and controlled (n = 4) before-after studies and randomized controlled trials (n = 6). Frequent user definitions varied considerably and risk of bias was moderate to high. Studies examined general frequent users or those with psychiatric comorbidities, chronic disease, or low socioeconomic status or the elderly. Interventions included case management (n = 18), care plans (n = 8), diversion strategies (n = 3), printout case notes (n = 1), and social work visits (n = 1). Post- versus pre-intervention rate ratios were calculated for 25 studies and indicated a significant visit decrease in 21 (84%) of these studies. The median rate ratio was 0.63 (interquartile range = 0.41 to 0.71), indicating that the general effect of the interventions described was to decrease ED visits post-intervention. Significant visit decreases were found for a majority of studies in subgroup analyses based on 6- or 12-month follow-up, definition thresholds, clinical frequent user subgroups, and intervention types. Studies reporting homelessness found consistent improvements in stable housing. Overall, interstudy heterogeneity was high. CONCLUSIONS: Interventions targeting frequent ED users appear to decrease ED visits and may improve stable housing. Future research should examine cost-effectiveness and adopt standardized definitions.
