Chronic dialysis and death among survivors of XXXX requiring dialysis.

@entity1 @entity740 @entity810
CONTEXT: Severe @entity810 among hospitalized @entity1 often necessitates initiation of short-term dialysis. Little is known about the long-term outcome of those who survive to hospital discharge. OBJECTIVE: To assess the risk of chronic dialysis and all-cause mortality in individuals who experience an episode of @entity810 requiring dialysis. DESIGN, SETTING, AND @entity1 : We conducted a population-based cohort study of all adult @entity1 in Ontario, Canada, with @entity810 who required in-hospital dialysis and survived free of dialysis for at least 30 days after discharge between July 1, 1996, and December 31, 2006. These individuals were matched with @entity1 without @entity810 or dialysis during their index hospitalization. Matching was by age plus or minus 5 years, sex, history of @entity740 , receipt of mechanical ventilation during the index hospitalization, and a propensity score for developing @entity810 requiring dialysis. @entity1 were followed up until March 31, 2007. MAIN OUTCOME MEASURES: The primary end point was the need for chronic dialysis and the secondary outcome was all-cause mortality. RESULTS: We identified 3769 adults with @entity810 requiring in-hospital dialysis and 13 598 matched controls. The mean age was 62 years and median follow-up was 3 years. The incidence rate of chronic dialysis was 2.63 per 100 @entity1 -years among individuals with @entity810 requiring dialysis, and 0.91 per 100 @entity1 -years among control @entity1 (adjusted hazard ratio, 3.23; 95% confidence interval, 2.70-3.86). All-cause mortality rates were 10.10 and 10.85 per 100 @entity1 -years, respectively (adjusted hazard ratio, 0.95; 95% confidence interval, 0.89-1.02). CONCLUSIONS: @entity810 necessitating in-hospital dialysis was associated with an increased risk of chronic dialysis but not all-cause mortality.
