Purpose Quality assessment of breast cancer treatment in South Korea showed the upward standardization of the grade since 2013, but treatment disparities still have existed. This study analyzed the 5-year trend between 2013 and 2017 in the assessment of breast cancer treatment practice using the Korean health insurance data.
Materials and Methods All the medical records including surgery, chemotherapy, and radiotherapy for 7,354 patients a year on average were evaluated. Twenty indices consisted of one structural, 17 process-related, and two result-related factors. We calculated the coefficient of variation (CV) annually to determine the variation in adherence rate of evaluation indices according to the type of institution (advanced vs. general hospital vs. clinic).
Results Based on the initial assessment in 2013, 10 out of 20 indicators showed significant variation among the types of institutions with a CV of less than 0.1%. Six of them had a CV decline of less than 0.1%. The CV was still 0.1% or higher in the four indicators, including the composition of professional staff, the implementation of target therapy, the average length of hospital stay, and the hospitalization cost. Regarding the first grade of assessment, there was a statistically significant relationship between the institution type (p=0.029) and region (metropolitan vs. province, p < 0.001).
Conclusion There were disparities in the structural and systemic treatment factors depending on the institutional type. The quality improvement of the regional institutions and multidisciplinary experts for breast cancer is necessary.
