Disparities in access to care at high-volume institutions for uro-oncologic procedures
Menée aux Etats-Unis sur la période 2003-2007, cette étude analyse les disparités socioéconomiques et ethniques dans l'accès à des hôpitaux réalisant un haut volume d'opérations de nature uro-oncologique
BACKGROUND: Socioeconomic status represents an established barrier to health care access. Age, sex, and race may also play a role. The authors examined whether these affect the access to high-volume hospitals for uro-oncologic procedures in the United States. METHODS: Within the Nationwide Inpatient Sample (NIS), the authors focused on radical prostatectomy (RP), radical cystectomy, and nephrectomy (Nx) performed within the 5 most contemporary years (2003-2007). Logistic regression models were used to estimate the impact of the primary predictors on the likelihood of receiving care at a high-volume hospital. RESULTS: Between 2003 and 2007, 62,165 RP, 6557 radical cystectomy, and 28,062 Nx cases were recorded within the NIS. Patient age (P = .001), year of surgery (P = .001), Charlson Comorbidity Index (P ≤ .025), median Zip Code income (highest vs lowest quartile, P = .001), and insurance status (private vs Medicare, P = .008) were independent predictors of being treated at high-volume institutions. Moreover, black race was an independent predictor of decreased utilization of high-volume institutions for radical cystectomy (P = .012), and female sex was an independent predictor of decreased utilization of high-volume institutions for Nx (P = .016). CONCLUSIONS: On average, old, sick, poor, and Medicare patients were less likely to be treated at high-volume hospitals for uro-oncologic surgery. Similarly, black patients were less likely to have a radical cystectomy at a high-volume hospital, and female patients were less likely to have an Nx at a high-volume hospital. Selective referral of individuals who are less likely to receive care at such institutions may represent a health care priority intended to optimize outcomes across all population strata.
