|Abstract: ||Purpose: Our purpose was to explore two methods of expressing
the performance of IVF programs.
Methods: Using life-table methods, hazard and cure rates
and a “monthly fecundability rate” were calculated for an
Ontario IVF clinic. The rates were evaluated for their meaningfulness
as indicators of the clinic’s performance.
Results and Conclusions: While the hazard rate describes
monthly fertility among those who will eventually become
pregnant, the fecundability rate describes fertility for all patients
who enter the program, making it the more appropriate
index for program comparisons. However, from a prospective
patient’s perspective, both methods are valid indices for
summarizing a program’s performance.|
