Introduction: Due to the low tariff of diagnostic and treatment services in hospitals as well as the high costs of delivering the health care services, the necessity of receiving all incomes from the insurance organizations can be justified. The purpose of this study was to investigate the effect of employee training on the amount of insurance fractions at Firoozgar Teaching Hospital.

Methods: The present study was longitudinal, analytical, cross-sectional, and applied in nature. The population consisted of the insurance documents of all hospitalized patients insured by the two insurance organizations of ‘Social Security’ and ‘Treatment Services’ (1685 and 1330 files, respectively) in Firoozgar Teaching Hospital during spring 2007 and spring 2008. Data were processed by SPSS software and were analyzed using paired t-tests. Results: The average percentage of management errors in insurance documents was 1.38 and 3.25 before and after the training, respectively. Furthermore, the amount of fractions decreased from 9.13 to 9.6 before and after the training, respectively. The effect of training on errors was confirmed considering both insurance organization types (P ≤0.001).

Discussion: Employee training significantly decreased the number of errors in insurance documents and the amount of insurance fractions at Firoozgar Teaching Hospital. Obviously, the administration of continuous and systematic educational programs can enhance the employees’ efficiency and partnership in decreasing the insurance fractions resulting in developing positive interactions with the representatives of the insurance organizations.
