Riddhi Vyas, Shankar Srinivasan

 Objective: The study reported here reviews the national trends of available procedures for inhospital treatment of lung cancer. Method: In this study the National Inpatient Sample (NIS) database from the year 2003 to 2011 was used and which has information about patients hospitalized with a principal diagnosis and with the principal procedure among other critical hospitalization related variables. The relevant data was extracted from NIS using the principal diagnosis ICD 9 code for lung cancer. The lung cancer procedures were classified into three categories (based on ICD 9 procedural code) as “Surgical”, “Non-surgical” and “Others”. Results: Overall it was found that 15,774 lung cancer patients were admitted to the hospital during the years 2003 to 2011. The percentage of “Non- Surgical” procedures and “Others” categories remained consistently lower (1.2%), whereas Surgical procedure increased by (6% to 8%) over the same period of time. Demographic factors of Age, Race, Gender and hospitalization outcomes of Length of stay in the hospital, Total charges, as also Type of admission to the hospital and Insurance Types were used alongside the review of the national trends to determine any significant association in the selection of treatment options for lung cancer. Total charges increased for all procedures over the period 2003 to 2011 (P-value<0.0001) while Length of stay reduced only for open surgery (P-value<0.0001). Gender, admission type and risk of mortality were found to play important roles in the selection of the treatment.
