In order to determine the status of Coronary Care Unit activity in California hospitals, especially as it pertains to nurse training, a survery was conducted by the California State Department of Public Health. More than 95 percent of hospitals that were questioned responded. Only one-third of the hospitals reported they neither had a unit nor plans to build one. All units in operation were either directed by an individual medical director or by a Coronary Care Unit Committee. The survey indicated that in some hospitals with operational units, nurses were not permitted to perform life-saving resuscitative procedures. All operational units reported in-service education programs of some type. Many hospitals indicated they would like to have Coronary Care Unit training programs to which they could send nurses. The reasons why nurses may not perform important resuscitative procedures are discussed as well as the need for Coronary Care Unit training programs for both physicians and nurses in California.
