Does cumulative hazard analysis of J-wire fracture in the Accufix series of atrial permanent pacemaker lead?
(1) The cumulative hazard function can be used to examine predictors of J-wire fracture and preliminary findings support the previously identified predictor of J shape; (2) Based on these analyses, the rate of J-wire fracture appears to decrease slightly as time from implant increases.
The lack of impact of the implementation process for a chest pain CPW on thrombolytic delivery or time to electrocardiogram in these rural hospitals can be explained by a ceiling effect in outcome measures but was also compromised by the small sample. Results suggest that quality of AMI treatment in rural emergency departments (EDs) is high and does not contribute to the worse mortality rate reported for AMIs in rural areas.
