It can be frightening any time a child is sick, leaving parents to debate whether a trip to the emergency department is necessary.

Such doubt is OK. Not every circumstance requires hospital care, says Kelly Orringer, M.D., director of general pediatrics at University of Michigan C.S. Mott Children's Hospital.

"When you're not sure what to do, call your pediatrician," she says.

But a new C.S. Mott Children's Hospital Poll on Children's Health found that caretakers don't always do this — or know another appropriate course of action.

Sore throats or minor burns, for instance, can be handled by a child's primary care doctor or an urgent care clinic. An emergency department is best equipped to treat difficulty breathing, seizures and change in mental status and severe bleeding, among other ailments, as well as major injuries and trauma.

Choking or a suspected swallowing of pills demands quicker action: Parents should call 911 or poison control, respectively.

But in the poll's nationwide sampling of 2,051 parents, only half were confident they would know what to do if their child were choking. And roughly 1 in 10 said they would take their young child immediately to the ED for a minor burn or ingestion of pills.

Coupled with the fact that 40 percent of surveyed parents lack first-aid training, the knowledge gap suggests families may rely too much on ED care in less severe scenarios — even though it comes with longer wait times and higher medical costs.

"Many visits to emergency departments are for nonemergent conditions," says Nicole Sroufe, M.D., M.P.H., medical director and service chief of children's emergency services at Mott.

That's why it's important for families to know the proper place to seek care.

Here's a breakdown to help make the decision easier:
