Institutional review board statement: This retrospective cohort study utilized the 2016 and 2017 National Inpatient Sample (NIS) databases. The NIS is a database of inpatient stays derived from billing data based upon discharge abstracts. As such, it contains de-identified clinical and nonclinical elements at both the patient and hospital level. Making the need for an Institutional review board approval dispensable.
Informed consent statement: The National Inpatient Database was a public-use dataset, of which the informed consent was waived.

Abstract
BACKGROUND

Epidemiological studies of chronic pancreatitis (CP) and its association with pancreatic ductal adenocarcinoma (PDAC) are limited. Understanding demographic and ethno-racial factors may help identify patients at the highest risk for CP and PDAC.

AIM

To evaluate the ethno-racial risk factors for CP and its association with PDAC. The secondary aim was to evaluate hospitalization outcomes in patients admitted with CP and PDAC.

METHODS

This retrospective cohort study used the 2016 and 2017 National Inpatient Sample databases. Patients included in the study had ICD-10 codes for CP and PDAC. The ethnic, socioeconomic, and racial backgrounds of patients with CP and PDAC were analyzed.

RESULTS

Hospital admissions for CP was 29 per 100000, and 2890 (0.78%) had PDAC. Blacks [adjusted odds ratio (aOR) 1.13], men (aOR 1.35), age 40 to 59 (aOR 2.60), and being overweight (aOR 1.34) were significantly associated with CP (all with P < 0.01). In patients with CP, Whites (aOR 1.23), higher income, older age (aOR 1.05), and being overweight (aOR 2.40) were all significantly associated with PDAC (all with P < 0.01). Men (aOR 1.81) and Asians (aOR 15.19) had significantly increased mortality (P < 0.05). Hispanics had significantly increased hospital length of stay (aOR 5.24) (P < 0.05).

CONCLUSION

Based on this large, nationwide analysis, black men between 40-59 years old and overweight are at significantly increased risk for admission with CP. White men older than 40 years old and overweight with higher income were found to have significant associations with CP and PDAC. This discrepancy may reflect underlying differences in healthcare access and utilization among different socioeconomic and ethno-racial groups.

Core Tip: What is known chronic pancreatitis (CP) and pancreatic ductal adenocarcinoma (PDAC) rates are rising. Pancreatitis admissions costed 133 million dollars, and accounted for the 3rd leading cause of hospital admissions. There is lack of data identifying those at highest risk for admissions with CP and PDAC. What we found Black men between 40-59 years old and overweight are at significantly increased risk for admission with CP. White men with higher income were found to have significantly increased risk for admissions with CP and PDAC. Asians/Pacific Islanders had the highest risk for mortality from CP and PDAC.
