Brief summary

The goal of this observational study is to learn about the risk factors, costs, and operational impacts of emergency department boarding (patients admitted to the hospital but remaining in the emergency department awaiting placement on an inpatient floor) The main questions it aims to answer is: 1. What characteristics of patients make them more likely to experience ED boarding? 2. What is the impact of ED boarding on costs of health care? 3. How do high-boarding environments affect the clinical care of all patients in the emergency department, including those that do not board themselves. Data will be secondary in nature, collected in the regular Participants already taking intervention A as part of their regular medical care for RA will answer online survey questions about their joint pain for 5 years.
