This study examined the relationship between multidisciplinary team (MDT) care and emergency department visits for lung cancer patients. Results show that lung cancer patients participating in MDT had lower risk to visit an emergency department, and the incidence rate ratio decreased by 11%. Gender, monthly salary, urbanization of the residence area, comorbid conditions, catastrophic illness/injury, treatment method, number of outpatient visits, length of stay, hospital ownership, level of hospital, and the age of the patient’s physician were all significantly related to the frequency of ED visits
