Objective: It is the purpose of this study to examine the relationship between hospital stays and a patient's race or social class with respect to the occurrence of appendicitis. These cases are drawn from the Healthcare Cost and Utilization Project of the 2004 Nationwide Inpatient Sample (NIS). Methods: We consider three outcomes: the amount of total charges the patient incurs; the length of the patient's stay; and whether or not the patient died. The sample was taken from 12,432 inpatient appendicitis cases from a 10% sample of the NIS. We used Kernel Density Estimates and multiple Logistic Regression Analyses to examine outcomes versus patient demographics and risk factors. Linear Regression Analysis examined charges and stay. Results: Patients in the second income quartile had the lowest total charges, but the highest rate of death. White patients had some of the lowest total charges, but again, the highest rate of death. There was no direct relationship between Patient Death and Race, Zip Code Income Quartile, Insurance or Primary Diagnosis. There was also no relationship between Length of Stay and Race, Zip Code Income Quartile, or Insurance. The Primary Diagnoses found to be directly related to Length of Stay were Rectosigmoid Junction Malignant Neoplasm, Volume Depletion, Hypopotassemia, Unspecified Anemia, Unspecified Congestive Heart Failure, Acute Appendicitis with Generalized Peritonitis, Acute Appendicitis with Peritoneal Abscess, Other Specified Gastritis, and all others combined. The remaining diagnoses— Pure Hypercholesterolemia and Diaphragmatic Hernia —were both inversely related to Length of Stay. However, no direct correlation may be seen between to lower the quality of health care and minority race or lower social class. Conclusion: In the end, it seems that demographic characteristics have little or no effect on quality of care in appendicitis cases. Length of Stay is largely determined, not surprisingly, by the patient's primary DRG code.
