A utilization analysis of maternal and newborn health service in Alberta (1997/1998 to 1999/2000)

It is dependent upon the quality of the data used to create the indicator and the frequency of the service event being looked at. [...] A delivery self-sufficiency index is created by dividing the number of deliveries provided to the residents of each of the provinces 17 RHAs in their home RHA by the number of deliveries provided to the region’s residents regardless of where they delivered in Alberta. [...] A larger distance between the top of the upper bar and the bottom of the lower bar represents greater variability in the accuracy of the point estimate. [...] The end of the bar closest to the black dot represents the value for a standard score of 1 or –1, while the end of the bar farthest from the dot represents the value for a standard score of 2 or –2. [...] Or to put it another way, we can be 95% sure that the true score for the indicator lies somewhere between the top of the upper bar and the bottom of the lower bar.
