Previous research has linked missed nursing care to nurses’ work environment. Ethical climate is a part of work environment, but the relationship of missed care to different types of ethical climate is unknown.

To describe the types of ethical climate in adult in-patient cancer care settings, and their relationship to missed nursing care.

A descriptive correlation design was used. Data were collected using the Ethical Climate Questionnaire and the MISSCARE survey tool, and analyzed with descriptive statistics, Pearson’s correlation and analysis of variance.

All nurses from relevant units in the Republic of Cyprus were invited to participate.

The research protocol has been approved according to national legislation, all licenses have been obtained, and respondents participated voluntarily after they have received all necessary information.

Response rate was 91.8%. Five types identified were as follows: caring (M = 3.18, standard deviation = 1.39); law and code (M = 3.18, standard deviation = 0.96); rules (M = 3.17, standard deviation = 0.73); instrumental (M = 2.88, standard deviation = 1.34); and independence (M = 2.74, standard deviation = 0.94). Reported overall missed care (range: 1–5) was M = 2.51 (standard deviation = 0.90), and this was positively (p < 0.05) related to instrumental (r = 0.612) and independence (r = 0.461) types and negatively (p < 0.05) related to caring (r = –0.695), rules (r = –0.367), and law and code (r = –0.487).

The reported levels of missed care and the types of ethical climates present similarities and differences with the relevant literature. All types of ethical climate were related to the reported missed care.

Efforts to reduce the influence of instrumental and independence types and fostering caring, law and code, and rules types might decrease missed nursing care. However, more robust evidence is needed.
