Objective To comprehensively explore the factors that affect the hospital average hospital stay and its quantitative relationship, so as to find targeted methods for the hospital, improve the hospital’s medical quality, and reduce the average hospital stay. METHODS: A total of 9176 patients were discharged from a large Beijing hospital in 1999. Multiple regression analysis was used to calculate the quantitative relationship between different factors and the day of hospitalization. Results The factors affecting the length of hospitalization are various, and the influencing factors include: the circumstances of the transfer, the number of days diagnosed, the year of birth, the incidence of multiple diseases, gender, the department of the hospital, the second diagnosis, marriage, hospitalization, and the date of admission. (P <0 0 5), but not related to Feibe, the third diagnosis outcome, the discharge month, the admission month, and the outcome of the first diagnosis (P > 0 05). Conclusion The plan to reduce the average length of hospital stay must be targeted and at the same time be based on the premise of ensuring the quality of medical care.
