Colorectal cancer screening in hospitalized patients: results from the Nationwide Inpatient Sample.

Colorectal cancer (CRC) is preventable with regular screening. This study aims to determine estimates and predictors of inpatient CRC screening during hospitalization in the USA. This nationwide population-based study utilized data from the National Inpatient Sample database from 2005 to 2014 to examine rates of CRC screening among hospitalized patients. There were 6470 inpatient CRC screening nationwide from 129 645 394 inpatient hospitalizations. Multivariable analysis showed that higher rates of inpatient CRC screening were associated with: females compared to males [odds ratio (OR): 0.87; 95% confidence interval (CI): 0.78-0.97]; 50-59 years age group compared to 70-79 years (OR: 0.76; 95% CI: 0.62-0.94) and more than 80 years (OR: 0.47; 95% CI: 0.35-0.64); Charlson Comorbidity Index score of 0 compared to scores of 1-2 (OR: 0.79; 95% CI: 0.64-0.98), 3-4 (OR: 0.61; 95% CI: 0.49-0.76), more than 5 (OR: 0.61; 95% CI: 0.47-0.79); rural hospitals rather than urban teaching hospital (OR: 0.50; 95% CI: 0.39-0.63) and urban nonteaching hospitals (OR: 0.64; 95% CI: 0.49-0.82); hospitals in the Midwest region (OR: 1.56; 95% CI: 1.14-2.12) compared to the Northeast region; recent years of 2011/2012 (OR: 1.89; 95% CI: 1.44-2.49) and 2013/2014 (OR: 2.70; 95% CI: 2.14-3.41) compared to the period 2005/2006. The CRC screening rate among hospitalized patients admitted in US hospitals is low. There were no association of differences in racial, household income or health insurance status with inpatient CRC screening. Noninvasive screening methods in hospitalized patients like stool-based fecal immunochemical test provide a unique method of increasing cancer screening rates.
