ABSTRACT
Objective:New approach and new methods on measuring disability weights of disease burden was developed and disability weights of diseases and injuries were calculated based on the sample of inpatient expenditure data in Beijing.Methods:Based on the inpatient medical records data of tertiary hospitals in Beijing from 2015-2017,diseases and injuries were classified according to the diagnosis and personal characteristics.Average expenditure of different diseases and injuries was calculated and relative disability weights were computed using the highest inpatient cost as the reference benchmark.The new methodology was developed for computing the relative weights of different diseases and injuries in burden of disease.Pearson correlation analysis was performed to test the consistency of the results.Results:The samples of 6.36 million inpatient medical records were analyzed and disability weights of 385 diseases and injuries were calculated with the results ranging from 0.020 to 0.995.The correlation coefficient between the results of 2012-2014 was 0.90.The results were consistent with the findings in other disability weights research,which made the classification of diseases and injuries more refined,reached to the most detailed classification level of diseases and injuries.Conclusions:The new approach was objective,simple,stable and repeatable with the low cost.It provided an innovative method for disability weights measurement.This was the first research to achieve the disability weights table of different diseases and injuries and it presented the key parameters for the research of burden of disease not only for China but also the other countries and regions.Furthermore,the new approach could be served as the significant reference for other countries and regions around the world to develop localized disability weights.
