Delays in diagnosis and treatment can lead to poor outcomes. In this population-based retrospective longitudinal study using inpatient and emergency department discharge data from four states, researchers found that non-Hispanic Black patients were at higher risk for delayed diagnosis of appendicitis compared to White patients. This increased risk for delayed diagnosis translated into higher risks for postoperative 30-day readmission rates. The researchers found that this risk was mitigated when Black patients received care at hospitals serving a more diverse patient population.
