Pre-Post Switch Cost Analyses (N = 105). aNone of these differences were statistically significant. bDefinitions: Standard Pre-Post: Costs incurred during the 60 days leading up to the last day on the initial medication are defined as 'Pre' period costs. Costs incurred starting from the day after the initial medication was discontinued for the next 60 days are defined as 'Post' period costs. Removed Overlapping Costs (Remove Overlapping Acute Crisis Costs from Post Period): Costs of acute care services that began while on the initial medication but continued into the 'Post' medication period were excluded from the analysis. Otherwise, calculations were the same as for the Standard Pre-Post analysis. Excluded first 2 weeks Post (Exclude first 2 weeks of the Post Period): Calculations follow the Standard Pre-Post Switch analysis except that the first 14 days of the 'Post' period were excluded from the calculations. Post 14 Days to Pre (Assign first 2 weeks of Post Costs to Pre Medication): Calculations follow the Standard Pre-Post Switch analysis except that costs occurring in the first 14 days in the post period are assigned to the Pre-treatment period.
