| Measure | Time frame |
|---|---|
| The percentage of users of NSAIDS in the period 6 months before the intervention and in the period 3 to 9 months after the intervention in comparison with the control group.

Secondary
| Measure | Time frame |
|---|---|
| The number of Defined Daily Doses (DDDS) of an NSAID in the period 6 months before the intervention and in the period 3 to 9 months after the intervention in comparison to the control group. The number of DDDS is determined by means of the amount of NSAIDS dispensed in the period 6 months before and 3 to 9 months after the intervention. The intervention is to be considered effective, if the mean number of DDDS of an NSAID in the period 3 to 9 months after the intervention is reduced by half in comparison with the mean number of DDDS of an NSAID in the period 6 months before the intervention. The number of users of NSAIDS with no concurrent use of a PPI in the period 6 months before the intervention and in the period 3 to 9 months after the intervention in comparison to the control group. There is concurrent use of a PPI with an NSAID if the period of use of a PPI has a ¡Ý 2/3 overlap with the period of use of an NSAID. The use is determined by collecting dispensing data from pharmacies 6 months before and 9 months after the intervention. The intervention is to be considered effective if the number of users of NSAIDS with no concurrent use of a PPI is reduced by half in the period 3 to 9 months after the intervention in comparison with the period 6 months before the intervention. | — |
