title: Statistical analysis of the intracranial procedures in Poland in 2008-2009.
abstract: OBJECTIVE
  Quantitative and qualitative analysis of neurosurgical procedures provides important data for assessment of the development and trends in the field of neurosurgery. The authors present statistical data on intracranial procedures (IPs) performed in Poland in 2008-2009.
  
  
  METHODS
  Data on IPs come from reports of the National Health Fund, grouped according to the system of Diagnosis-Related Groups, group A - nervous system diseases. Data concerning the year 2009 include all IPs performed in Poland. Data from the second half of 2008 to 2009 (18 months) come from 35 neurosurgical centers in Poland, divided by provinces. We analyzed the number of IPs, the cost of procedures, duration of hospitalization and deaths.
  
  
  RESULTS
  20 849 IPs were performed in Poland in 2009. The most common procedure was A12 (6807; 32.65%), and the rarest was A04 (96; 0.46%). The annual cost of all IPs was 228 599 956 PLN. Average cost of the procedure ranged from 1578 PLN (A14) to 47 940 PLN (A03). Duration of the hospitalization ranged between 3 days (A14) and 12 days (A12). The highest percentage of deaths was reported for A01 (n = 1050, 19.06%). Reports from 35 neurosurgical centers in the second half of 2008 and 2009 showed the highest number of IPs per 100 000 population in Kujawsko-Pomorskie (93) and the lowest in Wielkopolskie (27) and Podkarpackie (27). The highest number of IPs (1669) was performed in neurosurgical center M1 (Małopolskie), and the lowest (99) in W1 (Wielkopolskie).
  
  
  CONCLUSIONS
  A significant disparity in the number of IPs performed in different centers in Poland was observed.
