Survival was 63% following a deliberate overdose and 58% after therapeutic misadventure. For both groups, survival was independent of the level of alcohol consumption and the amount of paracetamol taken (Table 2). Renal dialysis was required by 54%
(278/515) of the deliberate overdose cases and 56%(21/38) of the therapeutic misadventure group, and there was no correlation with heavy alcohol consumption in either of the groups (Table 2). The need for inotropic support and the percentage of cases that fulfilled transplant criteria were similar in both groups, and also independent of the level of alcohol consumption (Table 2). Relatively few of those fulfilling transplant criteria had a transplant carried out: 37 in all (31 overdose, six therapeutic misadventure),and significant differences between the categories of alcohol consumption were not observed. There was no significant difference in the percentage of patients that developed grade III/IV encephalopathy (58% and 55% for therapeutic misadventure and deliberate overdose respectively) and there was no association with alcohol consumption (Table 2). Overall, there was no difference in the incidence of complications post deliberate overdose between drinkers and nonmembers drinkers, and the pattern of these complications was similar following both deliberate overdose and therapeutic misadventure
