BACKGROUND:A community hospital combined its medical and surgical patients with cancer on one unit, which resulted in nurses not trained in oncology caring for this patient population. OBJECTIVES:The Oncology Intensives Initiative (ONCii) involved the (a) design and implementation of a daylong didactic boot camp class and a four-hour simulation session and (b) the examination of nurses' worries, attitudes, self-efficacy, and perception of interdisciplinary teamwork. METHODS:A two-group, pre-/post-test design was implemented. Group 1 consisted of nurses who attended the didactic boot camp classes alone, whereas group 2 was comprised of nurses who attended the didactic boot camp classes and the simulation sessions. FINDINGS:Results of data analysis showed a decrease in worries and an increase in positive attitudes toward chemotherapy administration in both groups, as well as an increase in self-efficacy among members of group 2.
