Table 1 Start and end of analysis window within observation period for continuous, multiple interval, measures of medication availability
Adherence Measure | Start of Window | End of Window | Derivation |
|---|---|---|---|
CMA1 | Day of first prescription | Day before final prescription | \(\frac{\mathrm{Supply days obtained in window}}{\mathrm{Window duration}}\) |
CMA2 | Day of first prescription | End of observation period | \(\frac{\mathrm{Supply days obtained in window}}{\mathrm{Window duration}}\) |
CMA3 | Day of first prescription | Day before final prescription | minimum (CMA1, 1) |
CMA4 | Day of first prescription | End of observation period | minimum (CMA2, 1) |
CMA5 | Day of first prescription | Day before final prescription | \(\frac{\mathrm{Days with medication available in window}}{\mathrm{Window duration}}\) |
CMA6 | Day of first prescription | End of observation period | \(\frac{\mathrm{Days with medication available in window}}{\mathrm{Window duration}}\) |
CMA7 | Start of observation period | End of observation period | \(\frac{{\mathrm{Days with medication available }}^{a}\mathrm{ in window}}{\mathrm{Window duration}}\) |
CMA8 | Day that supply that was available at the start of observation period theoretically exhausted | End of observation period | \(\frac{{\mathrm{Days with medication available }}^{b}\mathrm{ in window}}{\mathrm{Window duration}}\) |
