The aim of this study was to estimate the frequency and rate of the first 50 common types of invasive procedures in Iran.


Data about the number of all invasive procedures and each type of procedure that were conducted in Iran in 2010 were collected using the main insurance organizations database. These numbers were sorted in an excel database, and the first 50 invasive procedures with the most common frequency were selected. Then according to the population covered by the given insurance organizations, and based on the total population of Iran in 2011, we estimated the number and rate of each invasive procedure for the selective procedures.


It was estimated that a total of 769,500 (1,026 per 100,000 population) natural vaginal delivery (NVD) was performed in Iran in 2011, followed by 416,790 cataract operation (556 per 100,000 population), 401,436 cesarean delivery (535 per 100,000 population), 260,514 coronary angiography disease (347 per 100,000 population), 181,836 varicocele (242 per 100,000 population), 144,918 appendectomy (193 per 100,000 population), 134,766 rhinoplasty (180 per 100,000 population) and 105,912 pilonidal cyst (141 per 100,000 population).


The result could be used to identify and select the most frequent invasive procedures in Iran, to calculate the average cost of each procedure and to use these costs to estimate hospital budget and improve policy-making.
