Introduction: The aim of this study was to quantify the effects of diabetes with pharmacotherapy-treated breast cancer on care resource use. Materials and Methods: The study was designed as a single institutional retrospective cohort study using hospital administrative data. The subjects were 152 patients admitted to a hospital from 2008 to 2012 diagnosed with breast cancer, and who underwent pharmacotherapy. We identified diabetes group and nondiabetes group in addition to other variables and quantified the effects of diabetes with breast cancer patients undergoing pharmacotherapy on care resource use, using a multilevel linear regression model. Results: Diabetes was significantly correlated to both longer length of stay (coefficient standard error: 0.75 [0.19], P < 0.001) and higher total hospital charge (0.72 [0.18], P < 0.001), controlled for age, pharmacotherapeutic agent, steroid use, admission route, procedures, and postpharmacotherapy events. Conclusion: This study showed that diabetes itself is a risk factor for greater care resource use after controlling for confounding factors. Pharmacotherapy for breast cancer may influence poor glycemic control, thus leading to greater care resource use. Early detection and careful monitoring of diabetes are essential in malignancy to eliminate this burden on the health care system.
