These infections are the sixth leading cause of death in the United States and the leading cause of mortality and morbidity in hospitals. Patients and hospitals will suffer financial consequences due to hospital-acquired infections, which will result in a longer length of stay and higher hospitalization costs. As a result, the aim of this study was to investigate the impact of hospital-acquired infections on hospital financial performance. Methods: This cross-sectional study examined hospital-acquired infections and their impact on hospital financial performance in 2019. We subtract hospital-acquired infections and financial performance data from the California Health and Human Services (CHHS) dataset. Hospital-acquired infection rate calculated in this study includes Clostridium difficile infections, Central Line-associated bloodstream infections (CLABSI), surgical site infections (SSI), and Methicillin-resistant Staphylococcus aureus bloodstream infections (MRSA-BSI). While operating margin, return on equity, and total asset turnover will be indicators of hospital financial performance. The researcher applied regression analysis to investigate the relationship between hospital-acquired infections and hospital financial performance. Results: According to the CHHS dataset, California has 438 hospitals, but only 362 hospitals reported their financial data. The study included 320 hospitals that reported CDI, 279 hospitals that reported SSI, 320 hospitals that reported CLABSI, and 322 hospitals that reported MRSA-BSI. The regression model shows that SSI has a marginally positive impact on operating margin (p<0.05). However, SSI has a negative impact on return on equity and total asset turnover, but the impact is insignificant (p>0.05). Other hospital-acquired infections, such as CDI, CLABSI, and MRSA-BSI, have a negative impact on operating margin, total asset turnover, or return on equity, but it is not statistically significant (p>0.05). Conclusion: Hospital-acquired infections may impact some hospital financial performance indicators. A longer length of stay, higher cost, and readmission due to HAI could be the cause. As a result, preventing HAI may reduce the negative impact on hospital financial performance. Keywords: Hospitals, infections, financial performance系所名稱：醫務管理學系碩士班thesis
