Hospital Statistics as a Tool for Obtaining Data Necessary in the Healthcare Entity Management Process

Statistical methods used by healthcare entities enable the collection of various information about the structure and characteristics of treated patients. They are an important source of knowledge, and form a database that plays an important role in entity management theory. In the presented study, we analysed the hospital stays of patients treated in all hospital wards of the 3^rd City Hospital in Łodź during 2012. The following, in particular, were taken into account: admittance procedure, discharge procedure, age and sex of hospitalised persons. Patients in over 55% of cases were admitted using the sud- den admittance procedure. At the same time, over 3/4 of the stays ended with a referral for further treatment in ambulatory conditions, and death occurred in approx. 5% of hospitalisations. By comparing the discharge procedures, the percentage of deaths in the Anaesthesiology and Intensive Care Wards can be seen clearly (more than 70%). Internal wards are next in turn (10.6 and 16.6%). The biggest differences in the length of hospitalisation between the studied institution and the NFZ data (which are averaged values from all medical entities in Poland) concern the E77, A49, A48, A87, A33, D18, E16, E61 and G37 groups.
