Comparison between early and late stage lung cancer in relation to cost and mortality

Lung cancer (LC) is a life threatening disease associated with significant cost and high mortality. LC is diagnosed in either early stage or more frequently in late stage, the face of lung cancer. Objective: To make a comparison between early and late stage lung cancer (SLC) in relation to cost and mortality Methods: The study is a random effects data analysis of a historical dataset the Nationwide Inpatient Sample (NIS). The study is based on the time period 2002, 2006 and 2011. The primary outcomes of interest is cost (total cost per day) and mortality (died/did not die). Two replicates samples for the years 2002, 2006 and 2011 were taken. Demographic factors that influence cost and mortality were co-varied out of the analysis. Descriptive Statistical analysis and bivariate analysis were done for cost includes ANOVA and ANCOVA. A statistical analysis for mortality includes logistic regression. Cost and mortality for early versus late (SLC) were measured in isolation and after accounting for age, gender, race, socio-economic status, number of diagnoses, length of stay, and number of procedures.Results: In the three years, 3 samples of 2173, 13,032, and 15,771 including 3 replicate samples of 2060, 13,032 and 15,772 participated in the study. All significant relationships tested at an alpha level of (P
