In addition, the in-hospital setting of our
intervention may be questioned since the majority of
prescribing decisions occur in outpatient settings.
However, our choice of setting was based on several
assumptions: (1) in Sweden, patients are hospitalised
only if really ill, and thus we regarded such patients to be
at high risk of DRPs and likely to benefit from the
intervention; (2) we considered transition from inpatient
to outpatient settings a major area of concern,
and (3) a hospital setting provided a more practical
means to implement an intervention than an outpatient
setting. Indeed, a low probability of cost-effectiveness has
been shown for medication reviews in an outpatient
setting.2
