Outcomes in hospitalisations of women with Turner syndrome compared to women without Turner syndrome.

OBJECTIVE To evaluate outcomes in patients with Turner Syndrome, especially those with cardiac conditions, compared to those without Turner syndrome. DESIGN Retrospective cohort study utilising hospitalisation data from 2006 to 2012. Conditional logistic regression models are used to analyse outcomes of interest: all-cause mortality, increased length of stay, and discharge to home. PARTICIPANTS We identified 2978 women with Turner syndrome, matched to 11,912 controls by primary diagnosis. RESULTS Patients with Turner syndrome were more likely to experience inpatient mortality (odds ratio 1.44, 95% confidence interval 1.02-2.02, p = 0.04) and increased length of stay (OR 1.31, CI 1.18-1.46, p = 0.03) than primary diagnosis matched controls, after adjusting for age, race, insurance status, and Charlson comorbidity index. Patients with Turner syndrome were 32% less likely to be discharged to home (OR 0.68, CI 0.60-0.78, p < 0.001). When restricting the sample of patients to those admitted with a cardiac diagnosis, the likelihood of mortality (OR 3.10, CI 1.27-7.57, p = 0.01) and prolonged length of stay (OR 1.42, CI 1.03-1.95, p = 0.03) further increased, while the likelihood of discharge to home further decreased (OR 0.55, CI 0.38-0.80, p = 0.001) in Turner syndrome compared to primary diagnosis matched controls. Specifically, patients with congenital heart disease were more likely to have prolonged length of stay (OR: 1.53, CI 1.18-2.00, p = 0.002), but not increased mortality or decreased discharge to home. CONCLUSIONS Hospitalised women with Turner syndrome carry a higher risk of adverse outcomes even when presenting otherwise similarly as controls, an important consideration for those treating them in these settings.
