Nursing homes provide services to an elderly person, who, due to permanent changes in physical and mental well-being, needs constant care of another person. In the Republic of Croatia, nursing homes are either publicly or privately owned. The main objective of this study was to examine whether psychiatric treatment of patients is different in publicly and privately owned nursing homes. I assumed that the proportion of patients who needed psychiatric care will not vary by age, gender, prior psychiatric treatment experience, and psychiatric diagnosis. Since the Nursing home Kantira is state-owned, I expected a significant difference in the psychiatric care of patients. Data was collected by reviewing the documentation of 200 patients of the Nursing home Kantrida in the period from 1 January 2018 to 31 December 2018; and 70 users of the Nursing home Nina in that same period. During that period, 35 patients of the Nursing home Kantrida home and 16 patients of the Nursing home Nina needed psychiatric intervention. The analysis of the data showed that there was no significant difference in average age, gender and patients who had previous psychiatric treatments. According to the established psychiatric diagnoses, there are more patients with an anxiety disorder in the Nursing home Nina, and the difference is statistically significant (p = 0.029). The only significant difference found was for the indication “weight loss, malnutrition ”, which was a significantly more frequent reason for seeking psychiatric intervention in the Nursing home Nina (p = 0.0269). No significant difference was found between the institutions with regard to the number of patients for whom a telephone consultation and psychiatric examination and hospitalization was requested. There is also no difference in the number of patients who were treated with a particular group of psychopharmaceuticals or were involved in psychotherapy. The number of psychiatric examinations is significantly higher in the Nursing home Kantrida. Most of the results were expected and in accordance with the set hypotheses. Appropriate professional care is provided for users with mental disorders in both institutions, which is shown by the small share of hospitalizations and the expected share of patients who received psychiatric care.
