Popis: 12073 Background: Thrombotic events are a common complication of lung cancer. We performed a retrospective analysis of an inpatient adult population (age ≥18) using the National Inpatient Sample (NIS) database from the years 2003-2014. Methods: The analysis was performed on the NIS database, using IBM SPSS Statistics 28.0.0.0 software. The cases for lung cancer were selected based on ICD-9(International Classification of Disease) codes for lung cancer. The cases were weighted by Weight to discharges in the universe. These cases were checked for a diagnosis of acute lower extremity Deep Vein thrombosis (DVT) and acute Pulmonary Embolism (PE) again using ICD-9 codes. Chi square tests were utilized to check the significance of association between mortality and DVT/PE. Independent T-tests were utilized to check the association of cost of hospitalization and length of stay with DVT/PE. Results: There were a total of 4,940,262 cases (53.0% male) of lung cancer from the years 2003-2014. 112,569 (2.3%) cases had a diagnosis of acute lower extremity DVT, and 164,208 (3.3%) cases had a diagnosis of acute PE. Overall, death for lung cancer cases was 516,070(10.5%). Death rate in patients with DVT was 12.4%(frequency = 13,943). DVT and death during hospitalization were positively associated, X 2 (1, N = 4,936,702) = 578.792, p 2 (1, N = 4,936,702) = 4540.012, p.000. DVT was associated with a prolonged length of stay ( M = 8.66 days, SD = 8.8.624), compared to cases without DVT ( M = 6.42 days, SD = 6.42), t(4,940,122) = 115.02, p =.000. DVT was also associated with increased total charges of hospitalization ( M = $ 62,950, SD = 85,105), compared to cases without DVT ( M = $ 41,764, SD = 55,410), t(4,864,517) = 124.09, p =.000. PE was associated with a prolonged length of stay ( M = 8.01 days, SD = 8.13), compared to cases without PE ( M = 6.42 days, SD = 6.41), t(4,940,122) = 97.89, p =.000. PE was also associated with increased total charges of hospitalization ( M = $ 56,161, SD = 76,585), compared to cases without PE ( M = $ 41,772, SD = 55,468), t(4,864,517) = 100.85, p =.000. Conclusions: DVT and PE are common complications of Lung Cancer. They are associated with increased mortality in these patients. DVT increases the mean LOS by 2.24 days, and mean charges by $21,186. PE increases the mean LOS by 1.59 days, and the mean charges by $14,389. Prevention of DVT and PE could help bring down the mortality, LOS and charges of hospitalization. This data provides support to the usage of prophylactic anticoagulation in patients with lung cancer as shown in recent trails with Direct Acting Oral Anticoagulants(DOACs), and further study of DVT/PE in Lung cancer patients would be warranted.
