Summary: | Background: Global payment system is a first example of per-case payment system that contains 60 commonly
used surgical operations for which payment is based on the average cost per case in Iran.
Objective: The aim of the study was to determine the amount of reduction, increase or no change in the trend of
global operations.
Methods: In this retrospective longitudinal study, data on the 60 primary global surgery codes was gathered from
Tehran Health Insurance Organization within the ten-year period of 2005-2015 separately, for each month. Out of
60 surgery codes, only acceptable data for 46 codes were available based on the insurance documents sent by
medical centers. A quantitative analysis of time series through Regression Analysis Model using STATA
software v.11 was performed.
Results: Some global surgery codes had an upward trend and some were downwards. Of N Codes, N83, N20,
N28, N63, and N93 had an upward trend (p<0.05) and N32, N43, N81 and N90 showed a significant downward
trend (p<0.05). Similarly, all H Codes except for H18 had a significant upward trend (p<0.000). As such, K
Codes including K45, K56 and K81 had an increasing movement. S Codes also experienced both increasing and
decreasing trends. However, none of the O Codes changed according to time. Other global surgical codes like
C61, E07, M51, L60, J98 (p<0.000), I84 (p<0.031) and I86 (p<0.000) shown upward and downward trends. Total
global surgeries trend was significantly upwards (B=24.26109, p<0.000).
Conclusion: The varying trend of global surgeries can partly reflect the behavior of service providers in order to
increase their profits and minimize their costs. |
