At some point you may get this call: your older loved one is in the hospital and doctors are monitoring the situation to determine what’s going on. With luck, nothing dangerous or life-threatening will be found and perhaps your loved one will leave the hospital after a day or two.

What is “observation” care and how do you know when an older patient’s care falls in that category? Find out from Kaiser Health News Here.
