Patients frequently choose the ED for apparent non-emergent medical issues or injuries that after-the-fact could be cared for in a primary care setting. We seek to better understand the reasons why patients choose the ED over their primary care managers.</p><p><strong>Methods: </strong>We prospectively surveyed patients that signed into the ED at the Brooke Army Medical Center as an emergency severity index of 4 or 5 (non-emergent triage) regarding their visit. We then linked their survey data to their ED visit including interventions, diagnoses, diagnostics, and disposition by using their electronic medical record. We defined their visit to be non-urgent and more appropriate for primary care, or primary care eligible, if they were discharged home and received no computed tomography (CT) imaging, ultrasound, magnetic resonance imaging (MRI), intravenous (IV) medications, or intramuscular (IM) controlled substances.</p><p><strong>Results: </strong>During the 2-month period, we collected data on 208 participants out of a total of 252 people offered a survey (82.5%). There were 92% (n=191) that were primary care eligible within our respondent pool. Most reported very good (38%) or excellent (21%) health at baseline. On survey assessing why they came, inability to get a timely appointment (n=73), and a self-reported emergency (n=58) were the most common reported reasons. Most would have utilized primary care if they had a next-morning appointment available (n=86), but many reported they would have utilized the ED regardless of primary care availability (n=77). The most common suggestion for improving access to care was more primary care appointment availability (n=96). X-rays were the most frequent study (37%) followed by laboratory studies (20%). Before coming to the ED, 38% (n=78) reported trying to contact their primary care for an appointment. Before coming to the ED, 22% (n=46) reported contacting the nurse advice line. Based on our predefined model, 92% (n=191) of our respondents were primary care eligible within our respondent pool.</p><p><strong>Conclusions: </strong>Patient perceptions of difficulty obtaining appointments appear to be a major component of the ED use for non-emergent visits. Within our dataset, most patients surveyed stated they had difficulty obtaining a timely appointment or self-reported as an emergency.
