title: The Relationship Between Social Deprivation and a Weekend Emergency Medical Admission.
abstract: BACKGROUND
  Deprivation increases admission rates; the specific effect of deprivation with regard to weekend admissions is unknown.
  
  
  METHODS
  We calculated annual weekend admission rates for each small area population unit and related these to quintiles of Deprivation Index from 2002-2014. Univariate and multivariable risk estimates were calculated using truncated Poisson regression.
  
  
  RESULTS
  There were 30,794 weekend admissions in 16,665 patients. The admission rate was substantially higher for more deprived areas, 12.7 per 1000 (95%CI 9.4, 14.7) vs 4.6 per 1000 (95%CI 3.3, 5.8). More deprived patients admitted at the weekend had a significantly lower 30-day in-hospital mortality (10.3% vs 14.5%, p<0.001).
  
  
  CONCLUSIONS
  Deprivation is a powerful determinant of weekend admissions, however these comprise a group of patients with better outcomes.
