The purpose of this study was to develop evaluation tools and monitor the quality of nursing care for oncological, para-oncological and medical surgical units. The survey of nursing care quality for oncological patients started on Oct. 1, 1994 and ended on Jan. 31, 1995. All medical and surgical wards from among 38 units were chosen as test units and a total of 210 oncological patients were monitored. Tests for inter-rater and intra-rater reliability were used. There was 90% agreement between 2 raters and 100% agreement in the observer herself for intra-rater reliability. The quality scores for Objective I "formulating nursing care plan" on oncological, para-oncological and medical-surgical units were 90.90, 83.90, 87.78; Objective II "attending patient's physical need" were 96.76, 96.05, 94.62; Objective III "attending patient's psycho-social-spiritual-culture needs" were 97.47, 96.05, 94.62 and Objective IV "the achievement of objectives" were 92.69, 90.80, 88.63. There were no significant difference on the quality of nursing care for the four types of patients on the same Objective scores except Objective III. There were significant differences on the quality of nursing care scores for Objectives 1, 2, 3, except the 4th type. The results helped nurses, nursing administrators, and educators know the strengths and weaknesses of nursing care and helped improve the quality of nursing care.
