Data Source
Data was obtained from the 2002 to 2007 Nationwide Inpatient Sample (NIS) datasets. NIS data represents the largest, all-payer, publicly available inpatient care database in the United States, providing a 20% random sample of US hospital discharges. The hospitals represented within these datasets are designated as “community hospitals” within the American Hospital Association annual survey. Data reported herein represents in-patient admissions for patients of all ages, races, income levels, and
Patient, Hospital, and Operative Characteristics
Descriptive statistics for select model covariates are presented in Table 1. Average patient age was 66.8 ± 10.5 years. Women accounted for 5.0% of the total study population. Among racial groups, whites underwent the large majority of operations (86.2%), followed by black (6.9%) and Hispanic (2.8%) races. The most frequent mean income quartile represented those earning more than $63,000 per year (mean income quartile IV). With respect to lung cancer resections, lobectomy was the most common
Comment
The present study reports on contemporary nationwide lung cancer resection outcomes in the United States as they relate to differences in gender, race, and socioeconomic status. These results suggest that after accounting for the potential confounding influence of more than 50 different variables, female gender was a significant, independent correlate of postoperative morbidity and mortality and was associated with reduced odds of death and postoperative complications compared with male gender.
