Plunkett PK, Byrne DG, Breslin T, Bennett K, silke B, Increasing wait times predict increasing mortality in emergency medical admissions, European Journal of Emergency Medicine, 18, 2011, Notes: [Abstract: Background: The actual impact of emergency department 'wait' time on hospital mortality in patients admitted as a medical emergency has often been debated. We have evaluated the impact of such waits on 30-day mortality, for all medical patients over a seven year period. Methods: All patients admitted as medical emergencies via the emergency department between 2002 and 2008 were studied; we looked at the impact of time to medical referral and subsequent time to a ward bed on any in-hospital death within 30 days. Significant univariate predictors of outcome, including Charlson co-morbidity and Acute Illness Severity Score, were entered into a multivariate regression model, adjusting the univariate estimates of the readmission status on mortality. Results: We studied 23,114 consecutive acute medical admissions between 2002-2008. The triage category in the Emergency Department was highly predictive of subsequent 30-day mortality ranging from 4.8% (Category 5) to 46.1% (Category 1). After adjustment for all outcome predictors, including comorbidity and illness severity, both Door to Team and Team to Ward times were independent predictors of death within 30 days with respective Odds Ratios of 1.13 (95% CI 1.07, 1.18), and 1.07 (95% CI 1.02, 1.13). Conclusion: Delay to admission can be shown to independently adversely influence mortality outcome. We recommend maximal target limits of 4 and 6 hrs for referrals and admissions respectively, based on these mortality observations.], Journal Article, PUBLISHED  DOI  URL
