If you have a serious, life-threatening illness or injury such as chest pain, uncontrolled bleeding, difficulty breathing or loss of consciousness, head straight for the emergency room or call 911. Unfortunately, many people go to the ER with problems that could be treated at an urgent care center, "quick care" clinic or even their doctor’s office. That drives up medical costs, because the hospital emergency room (ER) is generally the most expensive place to receive care (and often involves long waits.) If it’s not a life-threatening problem, always call your doctor’s office first for guidance on where to go for non-emergency medical issues. Another great resource: the "nurse line" services provided by many health plans. See the Learn More page for more help deciding on Hospital, ER or Urgent Care?
