Spirituality and spiritual needs are integral parts of the human experience, but they are often particularly important for palliative care patients. Spirituality has numerous positive effects, especially for those dealing with serious illness. Nevertheless, the spiritual dimension is sometimes overlooked in patient care. This study aims to determine the frequency of addressing the spiritual needs of palliative care patients in Croatia and to investigate the self-perceived confidence of caregivers in this task. A quantitative cross-sectional study was conducted involving 194 nurses in specialised palliative care services across Croatia. A specially developed and validated questionnaire was used for this study. The most common intervention undertaken by respondents was “promoting hope and optimism in patients” (88.4%), while the least common intervention was “reading books and other publications to patients” (13.9%). No statistically significant differences were found in the frequency of spiritual care in relation to the respondent’s level of education, professional experience and nursing environment. Approximately two-thirds of the surveyed nurses stated that they “often” or “always” provided some kind of spiritual care to palliative care patients. However, study participants who indicated that they had received sufficient formal instruction in addressing spiritual needs and spiritual care interventions demonstrated a statistically significant tendency to engage in these practices, as well as greater confidence in their knowledge and skills in this area compared to those who lacked such training. The study suggests that there is a need to identify existing barriers to the provision of spiritual care and to develop strategies to overcome them. By placing emphasis on the spiritual needs and preferences of patients, nursing professionals and other healthcare providers have the opportunity to elevate the standard of holistic care and foster a sense of comfort and dignity among patients.
