Researchers of a recent study said that many patients are not satisfied with the care they receive at U.S. hospitals. In the study the authors studied the data collected by the Hospital Consumer Assessment of Healthcare Providers and Systems survey in an ongoing survey of patients at all hospitals that get Medicare payments. Six areas were covered which were communication with doctors, with nurses and about medications; and quality of nursing services, discharge information and pain management. Almost one-third of patients gave low ratings to pain management, and one-fifth gave low ratings to communication at discharge.
