To determine if the percentage of medication orders containing errors improved after the installation of a computerized medication-tracking system, it is most effective to compare the proportion of erroneous medication orders before and after system installation. However, this comparison should account for any changes in the number of patients, as variations in patient numbers could skew the raw data. By adjusting for the number of patients, one can ensure that the comparison is fair and unbiased, leading to a more accurate conclusion regarding the effectiveness of the new system.
Why not C? Wouldn't the proportion change if the number of patients varied before and after implementation?
Comparable periods must be taken into account.
Why not D?
