The purpose of this paper was to determine the number and trend of hospitalisations caused by carcinoma in the Osijek-Baranja County, to to determine the proportion of these hospitalizations compared to all other hospitalization, as well as to determine the burden put on the hospitals by external patients (those not residing in the Osijek-Baranja County area). There has been an average of 10.1% of hospitalisations caused by carcinoma in the Osijek-Baranja County from 1998 to 2010. In the aforementioned period there have been an average 15.9% days of hospitalisation caused by carcinoma. Patients hospitalised due to carcinoma stay in hospital 5.3 days longer than other patients. The number of hospitalisations as a whole, as well as those due to carcinoma, is rising, while the number of days of hospitalisation per patient is decreasing. The number of hospitalisations which refer to men is slightly higher than for women (51.2%:48.8%). Almost one third of patients hospitalised are not residents of the Osijek-Baranja County due to a gravitational hospitalisation instance. Residents of northern Bosnia and Herzegovina are the most common patients being treated in our county. This burden has to be taken in to account when planning our health care due to the geographically, economically and politically specific situation of Osijek-Baranya County. This data has to be taken in to account when further planning our health care, as to relieve the acute medical situation hospitals of some of their burden, as well as to provide adequate care to patients suffering chronically from carcinoma. It is especially important to stress out that our county does not have a palliative care facility, nor a hospice for the terminally ill.
