Utilizing data from the 2010 Nationwide Inpatient Sample, Healthcare Cost and Utilization Project, the purpose of this study was to test the Sources of Healthcare Disparities Model by analyzing the relationship between race and ethnicity and the occurrence of Hospital-Acquired Conditions (HACs), after primary Total Hip Arthroplasty (THA) or Total Knee Arthroplasty (TKA) secondary to Osteoarthritis (OA). The effects of patient characteristics (gender, age, primary expected payer) and hospital characteristics (bed size, geographical region) were also considered.
Results suggest that increasing age is a significant (p = .038) predictor of the HAC catheter-associated urinary tract infection (β = 1.04, 95% CI [1.002, 1.08]). Further, increasing age (p < .001) was found to be a significant predictor of the HAC deep vein thrombosis or pulmonary emboli (β = 1.02, 95% CI [1.01, 1.02]). Hospital bed size was also shown to be a significant (p < .01) predictor of deep vein thrombosis or pulmonary emboli. Cases at medium bed size hospitals (β = 0.75, 95% CI [0.62, 0.9]) were less likely to suffer the HAC than those at small-size hospitals. Race (p < .001) showed significant influence on the occurrence of deep vein thrombosis and pulmonary emboli. Blacks (β = 1.02, 95% CI [1.01, 1.02]) and cases defined as ‘Other’ (β = 1.02, 95% CI [1.01, 1.02]) were less likely to be diagnosed with this HAC. Regarding manifestations of poor glycemic control, further research is needed to determine the influence of race and other factors.
