Frankly, such cases can happen, especially in private hospitals. But generally, the patient and the family members have to depend only on the attending physician. Only the doctor can actually know if ICU admission is required or not. Many a times the doctors prescribe ICU admissions even if not required. In such cases, the awareness of the family members comes to the help. If required, they can consult other doctors or change the hospital if the patient is not critically ill.
