Abstract:Purpose: National hospital volume standards are set to improve the quality of oncological care. The (changing) volume standards differ per tumor and treatment type. The purpose of this study is to analyze the development of tumor networks regarding hospitals within the region North East Netherlands in relation to the (changing) SONCOS volume standards over the period 2014 to 2019. Methods: This study focuses on volume standards regarding prostatectomy, lung cancer care, and breast cancer surgery. Social network analysis is applied to visualize and quantify the developments of the networks of these treatments. The key network characteristic is the density, which describes the proportion of present connections from all possible connections between hospitals in the network. The trend in density is compared to the change in volume standards. Breast cancer surgery had no change in volume standard over the period under study and was taken as a comparator. Results: For the three treatments, networks per year are visualized in sociograms. The number of hospitals inside the region North East Netherlands decreases. A reduction in density for the year 2019 with respect to 2014 is observed. Conclusions: Network development was observed for tumor types with (prostatectomy and lung cancer care) and without (breast cancer surgery) changing SONCOS volume standards. Reasons for this development are hospital mergers and changing SONCOS volume standards (for prostatectomy and lung cancer care).
