Expected lives saved increased from 25.2 to 26.3 per 1,000. This was derived from the reduction in mean pain-to-needle (PTN) time, using the equation published by Boersma et al. 1996, (see 'Other Publications of Related Interest' below for bibliographic details).
The mean PTN time decreased from 219.8 (+/- 23.6) to 197.6 (+/- 22.4) minutes, (p non significant).
The door-to-needle (DTN) time decreased from 37.6 (+/- 5.9) to 27.6 (+/- 3.6) minutes after the intervention, (p=0.06)
A total of 0.06 lives (95% confidence interval, CI: -0.09 to 0.33) were saved per year, which is the equivalent of 0.94 life-years gained (95% CI: -1.45 to 5.10). The calculation of the life-years gained used an anticipated mean life expectancy of 15.41 years following thrombolysis for acute MI (Mark et al. 1995, see 'Other Publications of Related Interest' below for bibliographic details).
