In the age of so-called affordable care, we like the idea of checking with a nurse about what the doctor is or isn't telling us. Centura offers one of several nurse hotlines in the area. Unlike Denver Health's round-the-clock operation, the Speak to a Nurse Hotline is available just twelve hours a day, but if you're calling during business hours, you can generally count on the friendly, accessible manner of the knowledgeable staff, who boast an average of 22 years of experience.
